BACKGROUND
[0002] In automobiles, a chassis of the vehicle primarily consists of a frame, a suspension, a pair of wheels and brakes. The chassis determines the main structure of the vehicle, its rigidity & also sets the overall looks of the type of vehicle. The frame must be torsion resistant so that the frame should not buckle on uneven road surfaces and any distortion should not be transmitted to the body parts and other aggregates.
[0003] With advancement in technology, the extent of electrical and electronic devices being incorporated into a vehicle is increasing rapidly. Most vehicles today have at least one or more systems of the vehicle being controlled and operated by a controller also referred to as an Electronic Control Unit (ECU). While the major aggregates of the vehicle like frame, power unit, wheels, etc. have remained unchanged, the same vehicle now has a greater number of electrical hardware in form of sensors, controllers, wiring harness, etc. to be able to enhance the performance and reliability of the vehicle as a whole. Despite addition of electrical aggregates, the overall dimensions of the vehicle have been more or less the same or being reduced to design more and more compact vehicles. Designers are continuously innovating new layouts of the vehicles to be able to package additional hardware within the same major exterior dimensions of the vehicle.

DETAILED DESCRIPTION
[00013] Typically, saddle type vehicle includes a frame assembly comprising a main frame, a head pipe, a down frame, centre frame in front zone of the vehicle and, seat rails, pillion handle assembly in rear zone of the vehicle, The frame assembly provides stiffness and strength for withstanding the forces acting thereon. The head pipe supports a steering assembly along with a front telescopic suspension of the vehicle. The rear zone of the vehicle also includes a rear wheel, and a rear suspension assembly connected. A power unit is mounted between the down frame and centre frame of the saddle type vehicle. Therefore, the front zone and rear zone of the vehicle is subject to various forces from the front and rear wheel through the suspension and from the power unit in addition to the payloads arising out the occupants & goods. Moreover, the vehicle is provided with style parts that are mounted to the frame assembly for providing utility space and aesthetic appeal, which are mounted with minimal gaps & in a manner so as to withstand vibrations. The front zone and rear zone of the vehicle also includes various electrical components as per the requirements in the vehicle.
[00014] Further, electrical system of the saddle type vehicle has evolved over the years and it assimilates automatic computer control of the automotive systems. Earlier the saddle type vehicles comprised of basic wiring technologies that were used for distributing power to the other parts of the straddle type vehicle and today’s electrical system comprises of ISG controller, sensors, actuators, energy storage unit etc.
[00015] It is essential for the electrical components to be disposed in a rigid fashion, unmovable except by removal or adjustment through use of tools. It is imperative for the electrical components to be located in the vicinity capable of sensing data. The proximity of electrical components with neighboring components helps to perform its intended function in an efficient manner. The location of the electrical components and access to the air flow for effective cooling in the vehicle plays an important role in maintaining the efficiency and accuracy of the signal sent by the components and thereby determines the reliability of the electrical systems. A rigid mounting is necessitated to prevent undesirable displacement or loosening of the electrical components like energy storage unit, an ISG controller, or any other electrical equipment. Further, the rigid structure is necessitated to prevent one of the pluralities of equipment from interfering or damaging another of the plurality of components by change in position or angle of any of the plurality of equipment with respect to each other. Typically, in the vehicle, the electrical components like the ISG controller have to be disposed without any interference from the surrounding components and also should not compromise with the efficiency and functionality of the surrounding components. Additionally, electrical components need to be secured in a safe location so as to be avoid potential fire accidents as well as protect them from environmental factors like rain, mud splash etc.
[00016] Further, there is always a contradicting challenge of providing a stable mounting structure for the electrical components unit like energy storage unit, the ISG controller, and at same time enabling ease of assembly, access for manufacturing, service, diagnostics and being exposed to cooling air. Among the various controllers that are configured on a vehicle, the controllers which are prone to heat generation need special attention to be able to perform in a safe and reliable manner. For example, conventionally, the ISG controller is mostly mounted on the frame assembly of the vehicle, e.g. mounted below seat assembly between the seat rails behind the power unit, or anywhere in the compact location. The ISG controller in this location is without any air flow which may lead to overheating and safety hazards. Additionally, such layouts raise problem related to serviceability, assembly of the components, etc. The absence of flow of air affects the efficiency of the ISG controller as the heat generated by the ISG controller is not dissipated in the atmospheric air and hence the ISG controller might not perform satisfactorily. Also, disposing the ISG controller away from the main structural members of the frame like as power unit, energy storage unit etc. tend to decrease the efficiency of the ISG controller because of the heating of the ISG controller. Further, elongation of wire connection between the ISG controller and energy storage unit leads to voltage drop in the wires, which affects the efficiency of the ISG controller. Additionally vibration in vehicle can cause wires to break especially at the joints where the wire feeds into a connector. Moreover, there is often need to package other electrical components in close vicinity to the energy storage unit and power unit. Multiple means are provided on the vehicle structure to mount the electrical component which makes the system design complex, costly, difficult to manufacture & undesirable. Typically, the electrical components are disposed on the vehicle structure with plurality of mounting means that eat away into additional valuable layout space of the vehicle, adds to cost, increases number of parts & aggravates the ease of assembly & access to tools for mounting the battery unit to the vehicle. Further, the frame assembly is prone to vibration and noise, which also affects the efficiency of the ISG controller. So, there is a need of improved layout configuration of a vehicle to be able to mount the ISG controller in a frame assembly such that the efficiency and the accuracy of performance of the controller does not get hampered by the metal contact and also should not get hampered by the vibration and noise of the frame assembly. There is also a need to have a layout design of a vehicle with an ISG controller which cools effectively by enabling flow of air during usage of the vehicle.
[00017] In known art, electrical component like the ISG controller is mounted in vicinity of utility box in between the seat rails, which eats into space of surrounding components like utility box, air cleaner of the saddle type vehicle and also increases seat foam thickness which leads to compromise with ground clearance of the vehicle.
[00018] Further, in another known art, electrical component like the ISG controller is disposed in cover frame of the vehicle. It leads to additional problems like increased width of the cover frame. This leads to change in the layout of the vehicle and make the vehicle bulky. Further, the cover frame is provided with a slot to dissipate heat generated by the ISG controller and surrounding components. This hot air as dissipated by the slot hit the legs or thighs of a rider riding the vehicle, which leads to discomfort of the rider while riding the vehicle.
[00019] Thus, there exists a challenge of designing an improved vehicle layout and mounting scheme, which can satisfactorily accommodate electrical components like integrated starter generator controller within a compact layout of a saddle type vehicle while maintaining a constant air flow in the vicinity and ensuring ease of accessibility. Additionally there exists a challenge of designing a flexible platform architecture solution to mount the integrated starter generator which is to be implemented in a variety of vehicle variants & platforms without any major change in design and manufacturing set-up of the range of vehicles.
[00020] Therefore, there is a need to have an improved mounting scheme for the integrated starter generator for a saddle type vehicle which overcomes all of the above problems and other problems known in art.
[00021] The present subject matter discloses a mounting scheme for the integrated starter generator to ensure the stable, secure and safe mounting of the integrated starter generator and also, make it as theft proof.
[00022] As per one aspect of present invention, a frame assembly of the motorcycle type saddle vehicle comprises of a head pipe, a main frame, a down frame etc. The main frame is extended rearward from the head pipe. Further, as per one aspect of the present invention, a fuel tank assembly is mounted on the main frame with various attachment means, for example, fasteners. The down frame extended backward after it is extended downward from the front of the main frame. As per one aspect of the present invention, a frame reinforcement member is integrally attached with the main frame and the down frame. The frame reinforcement member extends from the head pipe and supports initial part of the main frame and the down frame. This configuration provides support to the main frame and the down frame of the frame assembly and thereby, ensuring the rigidity of the frame assembly. A power unit is mounted in space provided between the down frame and the centre frame in the vehicle.
[00023] Further, as per one aspect of the present invention, the frame reinforcement member is designed with a C shaped profile. As per one aspect of the present invention, electrical component like an ISG controller is detachably attached with the frame reinforcement member. The ISG controller is disposed inclinedly with respect to ground plane. The ISG controller has plurality of extended members A & B disposed at extreme right and left end of the ISG controllers. The extended member A is tilted towards the centre frame of the frame assembly. The extended member B is tilted towards the head pipe of the frame assembly. The extended member A and extended member B of the ISG controller is detachably attached to the left and right side of the frame reinforcement member with various attachment means like plurality of fasteners and are substantially equidistant in both longitudinal and lateral direction, ensuring rigid and stable mounting of the ISG controller with the frame reinforcement member of the frame assembly and preventing the ISG controller from sagging. This configuration ensures that the efficiency of the ISG controller is not affected by the vibration generated and eliminates any direct contact with the metal member of the frame assembly. This configuration also ensures ease of serviceability and ease of assembly of the ISG controller Further, the extended members of the ISG controller act as the self-guiding member as it is configured to overlap with the mounting provision present on left and right side of the frame reinforcement member, ensuring fool-proof or error proof assembly of the ISG controller with the frame reinforcement member. As a result, this restricts the wrong assembly of the ISG controller.
[00024] Further, as per one aspect of the present invention, the ISG controller has fins which channelizes atmospheric air to dissipate the heat generated by the ISG controller. The mounting of the ISG controller inclinedly increases surface area of contact of the ISG controller with the atmospheric air, ensuring proper flow of atmospheric air to the ISG controller as disposed in the vehicle. The configuration ensures the constant flow of air in the vicinity of the ISG controller.
[00025] Further, as per one aspect of the present invention, the ISG controller is disposed such that couplers of the ISG controller are projected in one side of the vehicle with respect to vehicle mid plane axis. Further, an energy storage unit is also disposed on same side as the couplers, with respect to vehicle mid plane axis. This configuration of components ensures that routing of wiring harness in the vehicle is shortest and simplified and also eliminates tilting and pinching of the wiring harness. As the routing of wiring harness is shortest, hence it also minimizes the voltage drop in the wire. As the couplers and the energy storage unit are disposed on same side of the vehicle with respect to vehicle mid plane axis, it eliminates probability of breaking of wires at connector end.
[00026] As per one aspect of the present invention, the ISG controller is inclinedly disposed on the frame reinforcing member having C shape and above a cylinder head of the power unit. The ISG controller as disposed provides enough clearance to the surrounding components like the power unit, thus restricting the ISG controller from fouling with surrounding components like the power unit and facilitating ease of serviceability and ease of assembly of the surrounding components. Also, this configuration ensures that a front area of the power unit channelizes maximum air flow to dissipate heat generated in the power unit by directing the heated air away from the ISG controller.

The vehicle (100) having lighting means which includes Head lamp (127), Tail lamp (not shown), Turning indicators includes front side indicators (111) and rear side indicator (not shown) respectively. The rear fender (138) is projected outwardly of the vehicle systems to protect the pillion from mud splash as well as to protect the rear wheel (133) from external environmental damage. A power unit (125) is mounted to the lower portion of frame (200) with an ISG machine (125i) disposed thereat co-axially with the driveshaft axis (DA shown in Fig 4) of the power unit (125). In an embodiment, the power unit (125) is an IC engine. The fuel tank (103) is functionally connected to the power unit (125). A seat (132) is located at the back region of the fuel tank (103) and is extended in a longitudinal direction along the seat frames.
[00031] The frame assembly (200) of the vehicle (100) is provided with a head pipe (201) that includes a main frame (202) extended backward and diagonally downward from the head pipe (201), a pair of seat frames (204) extend backward from the rear of the main frame (202), a down frame (206) extends rearwardly downward from the front of the main frame (202), the power unit (125) is coupled between a pair of center frames (203) and the rearward end portion of the down frame (206). An area enclosed by the seat frames (204), the center frames (203) and a pair of sub frames (205) is substantially triangular in a side view.
[00032] The fuel tank (103) is provided across the main frame (202) and at the front region of the pair of seat frames (204) in a side view and covers the main frame (202) and partially overlaps the sides of the seat frames (204).
[00033] As per one embodiment of the present invention, a frame reinforcement member (208) is integrally attached with the main frame (202), the head pipe (201) and the down frame (206) of the frame assembly (200). The frame reinforcement member (208) extends from the head pipe (201) and supports initial part of the main frame (202) and the down frame (206). This configuration provides support to the main frame and the down frame of the frame assembly and thereby ensuring the rigidness of the frame assembly.
[00034] Fig. 3 is a partial exploded perspective view of front region of the frame assembly showing assembly of ISG controller with frame reinforcement member. Further, as per one embodiment of the present invention, the frame reinforcement member (208) has C shaped profile (C). As per one embodiment of the present invention, electrical component like an ISG controller (301) is detachably attached with the frame reinforcement member (208). In another implementation, electrical components power controller e.g. an EFI controller can be disposed on the frame reinforcement member. The ISG controller is disposed inclinedly with respect to ground plane of the vehicle, in a side view of the vehicle and is at least partially overlapped by the frame reinforcement member (208), in a front view of the vehicle. The ISG controller (301) has plurality of extended members A & B (302b, 302a) disposed at extreme right and left end portion of the ISG controller and being disposed substantially on the larger surface area CA of the ISG controller. As per an embodiment, the extended member A (302b) is oriented partially inclided towards the centre frame (203) of the frame assembly and the extended member B (302a) oriented towards the head pipe of the frame assembly. The extended member A (302b) and extended member B (302a) of the ISG controller is detachably attached to the left (208a) and right side (208b) (as shown in fig. 3a, 3b)of the frame reinforcement member with various attachment means like plurality of fasteners (303a, 303b. The ISG controller is disposed laterally symmetrically on the frame reinforcement member (208), ensuring rigid and stable mounting of the ISG controller with the frame reinforcement member of the frame assembly and preventing the ISG controller from sagging. This location and mounting method ensures that the efficiency of the ISG controller is not affected by the vibration generated and eliminates any direct contact with the metal member of the frame assembly thereby enhancing vibration isolation. This configuration also ensures ease of serviceability, ease of assembly of the ISG controller as well as does not adversely impact the handling performance of the vehicle. . Further, the extended members of the ISG controller act as the self-guiding member as they overlap in a abutting manner with the mounting provision present on the left and right side of the frame reinforcement member (as shown in fig. 3a & fig. 3b), eliminating need of additional components for mounting the ISG controller on the frame reinforcement member, eliminating overhanging of the ISG controller and ensuring fool-proof or error proof assembly of the ISG controller with the frame reinforcement member. The diagonal conjugate disposition of the mounting means (302a, 302b) on the controller and the corresponding mounting means on the frame eliminate and wrong assembly of the ISG controller. As per an aspect of the present invention, the ISG controller (301) as shown in Fig 2 is disposed substantially in the arc sector formed by the C shape of the frame reinforcement member (208). As per an aspect, more than half of the ISG controller (301) lies on the inner arc side of a line LL’ formed by joining the rearmost ends of the frame reinforcement member (208). The gap G created between the ISG controller larger surface and the C profile enables ventilation and cooling of the ISG controller thereby enhancing its efficiency and durability. As per another embodiment, the frame reinforcement member may be designed to have a profile which conforms to the abutting surface of the ISG controller (301).
[00035] Further, as per embodiment of the present invention, the ISG controller (301) has fins (301a) on its larger surface CA which channelizes atmospheric air to dissipate the heat generated by the ISG controller. The mounting of the ISG controller inclinedly increases surface area of contact of the ISG controller with the atmospheric air, ensuring proper flow of atmospheric air to the ISG controller as disposed in the vehicle. This configuration ensures the constant flow of air in the vicinity of the ISG controller. This mounting means also ensures the rigid mounting of the ISG controller. In another implementation, the vehicle is provided with a shroud (304) which channelizes atmospheric air towards the electrical component (301) as disposed on the frame reinforcement member (208), ensuring efficient cooling of the electrical component (as shown in fig. 3c). As per one embodiment of the present invention, the electrical component like the ISG controller (301) is at least partially overlapped with the fuel tank (103), in a top view of the vehicle, ensuring location of the ISG controller is theft as well as tamper proof.
[00036] Fig. 4 is a top view of the vehicle as per one embodiment of the present invention. As per one embodiment of the present invention, the ISG controller is disposed such that couplers (301b) of the ISG controller are disposed at least partially on one side of the vehicle with respect to vehicle mid plane axis (XX’). Further, an energy storage unit (401) is also disposed in same side as the couplers, with respect to vehicle mid plane axis (XX’). This configuration of components ensures that routing of wiring harness in the vehicle is shortest and simplified and also eliminates tilting and pinching of the wiring harness. As the routing of wiring harness is shortest, hence it also minimizes the voltage drop in the wire. As the couplers and the energy storage unit are disposed on same side of the vehicle with respect to vehicle mid plane axis, it eliminates probability of breaking of wires at connector end. This configuration also provides ease of accessibility, ease of assembly and disassembly of couplers and connection of diagnostic tool with the couplers without disturbing mounting of surrounding components. As per another embodiment, the ISG machine (125i) is configured on one of a left and a right side of the vehicle mid plane axis (XX’) such that the ISG machine is on the same side as that of the energy storage unit or on the opposite side. Various permutations of the disposition of the ISG machine and the energy storage unit are feasible based on the layout requirements of a vehicle and the manufacturer. Vehicle layout can be formed such that an opposite disposition of the ISG and the energy storage unit enables enhanced mass balance of the vehicle. A same side disposition enables enhanced wiring harness of the high as well as the low voltage routing to enable ease of assembly, eliminate safety hazard as well as avoid electromagnetic interference thereat.
[00037] Fig. 5 is a left side view of the vehicle with assembled ISG controller as per one embodiment of the present invention. As per one embodiment of the present invention, the ISG controller (301) is inclinedly disposed on the frame reinforcement member having C shape profile and above a front part and upper part (shown by YY’) of the power unit, i.e., e.g. above a cylinder head (125a) of the power unit (125) wherein the line YY’ is substantially parallel to the uppermost portion of the power unit. More precisely, lower end of the ISG controller is above upper end of the cylinder head of the power unit. The ISG controller as disposed provides enough clearance to the surrounding components like the power unit, thus eliminating any fouling of the ISG controller with surrounding components like the power unit and facilitating ease of serviceability and ease of assembly of the surrounding components. Also, the lateral attaching means to mount the ISG controller as per the present invention enables ease of ingress and egress of the ISG controller from the space between the C shape profile of the frame reinforcement member and the power unit. This configuration also ensures that a front area of the power unit & the ISG controller channelizes maximum air flow to dissipate heat generated in the power unit as it maintains gap between the ISG controller and the power unit in the vehicle.
