, Description:TECHNICAL FIELD
[0001] The present subject matter described herein generally relates to a vehicle. More particularly, a saddle type vehicle disclosed in the patent application number 202041052010. The present subject matter offers an improvement over the subject matter as claimed in the aforementioned patent application.

BACKGROUND
[0002] Typically, an Electronic Fuel Injection (EFI) system is coupled with an Electric control Unit (ECU) and uses various sensors to control an internal combustion engine towards reducing emissions, fuel economy as well as meeting driveability requirements of a vehicle. Further, to reduce excess fuel consumption, an Integrated Starter Generator (ISG) is also incorporated in vehicles. The ISG cranks the engine and generates assisting power as well as functions as a magneto to charge the vehicle battery and / or supply power to one or more electrical loads of the vehicle. In some cases, the ISG is also provided with automatic idle start-stop functionality. Accordingly, when the vehicle momentarily halts, the ISG senses the same and shuts off the engine to save consumption of the fuel. Once the user actuates throttle of the vehicle, the ISG starts the engine immediately thus reducing the fuel consumption. As such, the ISG is also coupled with the ECU which controls the operation of the ISG.

DETAILED DESCRIPTION
[00014] An ECU is a type of a control unit which is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a vehicle. Conventionally, the electronic engine control unit (ECU) is the central control unit and heart of the engine management system. It controls the fuel supply, air management, fuel injection and ignition. Due to the scalability of its performance, the control unit is also able to control the exhaust system as well as to integrate transmission and vehicle functions. The ECU manages all types of powertrain and topologies such as Gasoline, Diesel, CNG, Ethanol and also Hybrid and Fuel Cell system.
[00015] Therefore, the ECU is capable of managing, prioritizing and implementing nearly all requirements for the engine and overall powertrain in general. Examples of requirements include accelerator pedal position and exhaust system requirements for the mixture composition. Besides combustion relevant functions the electronic control unit also includes security, safety and diagnostics functions.
[00016] Types of ECU include engine control module (ECM), powertrain control module (PCM), Transmission Control Module (TCM), Brake Control Module (BCM or Electronic BCM EBCM), Central Control Module (CCM), Central Timing Module (CTM), General Electronic Module (GEM), Body Control Module (BCM), Suspension Control Module (SCM), control unit, or control module. Taken together, these systems are sometimes referred to as the vehicle's computer though technically there is no single computer but multiple ones. Sometimes one assembly incorporates several of the individual control modules. Some modern vehicles can have up to 80 ECUs installed in the vehicle body. Managing the increasing complexity and number of ECUs in a vehicle has become a key challenge for original equipment manufacturers (OEMs) and hence therefore is a need of an reliable and secure mounting of the ECU across vehicles given that these need to be packaged into the existing layout constraints of the vehicle. The challenge becomes more complex in case of a saddle type compact vehicle.
[00017] Generally, two-wheeler vehicles are provided with an integrated starter-generator (ISG). The ISG is an electrical machine that is capable of performing both the starting and generation operations. Typically, a single control unit is used in such vehicles as an integrated control unit, that can operate both the ISG and also as an engine control unit. There may be a single integrated control unit or two separate control units separately controlling the ISG and the engine depending upon the necessity and the design of the vehicle.
[00018] Usually in such two wheeled vehicle, design of a single integrated control unit makes it larger and bulky requiring considerable space to be mountd safely as well as securely within the vehicle. Similarly, when two separate control units are used, a separate defined space is required for both the control units controlling the engine and the ISG as well as considerable number of wiring harness.
[00019] Typically, some known arts disclose mounting of the control unit such as an ECU or an ISG control unit below a seat assembly of a vehicle. Some other known arts specifically disclose disposal of the ECU on a middle part of frame of a vehicle, which is usually positioned below the seat cushion, while the inner chamber of the ECU mount is usually sealed by the seat cushion.
[00020] Such disposal of the ECU below the seat of the vehicle occupies considerable space which further compromises with the intended utility space below the seat. This is a major challenge, especially in motor vehicles with a step-through layout as the user expects large amount of utility space below the seat considering the needs of accommodating two helmets or even a full mask helmet or other requirements related to storage.
[00021] Certain known arts also disclose about providing a fuel tank below the seat of the vehicle along with the utility unit. In such vehicles where already the utility space is limited because of the fuel tank presence; an additional provision for providing two control units or a single large integrated control unit either further compromises with the utility space or eats into volume of the fuel tank.
[00022] Also, other known arts disclose about usage of an additional bracket or a cross-member that needs to be provided to mount the control unit such as the ECU(s) or the ISG control unit on to the frame below the seat. In such scenarios if a bracket is provided for mounting the control unit, an extra space needs to be created for accommodating the bracket and the control unit. This extra space is usually between a style panel of the vehicle and the utility space. When such additional bracket is used, it again affects the utility space as the additional bracket mountd on the style panel runs across the rear frames of the vehicle. Therefore, because of such additional bracket either the utility space is compromised or the style panels of the vehicle are required to be made wider to mount the additional bracket.
[00023] Some other known arts disclose about accommodating the control units such as an ECU(s) or ISG itself within the side panels of the vehicle. Again, because of such accommodation within the style panels of the vehicle, the style panels needs to be made wider as well as stiffer to mount the control unit (s) both of which are undesirable owing to adverse impact on weight and compact vehicle layout.
[00024] Further, such location of the control unit (s) below the seat or within the side panels poses serviceability issue, as the utility box or the side panels or both require to be removed in order to access the control unit (s) making the whole servicing process cumbersome and time consuming.
[00025] Moreover, since in above disclosed known arts usually the electrical components, for example a battery is located at a different location than that of the control unit (s), such a configuration creates the problems in electrical fault detection due to long wiring harness. This is a major challenge because, the battery, ISG controller and the ECU(s) for controlling the ISG and the battery are critical components of the vehicle, and require time to time inspection of electrical connections between them to ensure timely electrical faults detection.
[00026] Hence, there is a need to create an improved layout design for configuring of the control unit (s) in the vicinity of the critical electrical components which overcomes all problems cited above and other problems from known art. The improved layout design needs to be also suitable for a compact saddle type vehicle while eliminating the need of the additional brackets, such that the improved layout achieves ease in accessibility, serviceability as well as fault detection in electrical components is achieved.
[00027] The present subject matter has been devised in view of the above circumstances as well as solving other problems of the known art.
[00028] The present subject matter discloses a saddle type vehicle comprising a rear panel and a control unit.

The upper portion on its rearmost region on both sides is configured with a dedicated housing for electrical components such as an ECU unit, an ISG controller, a battery controller or other electrical components such as a fuse, a relay, etc.
[00032] As per another aspect of the present embodiment, the fender unit includes one or more vertical outer or inner ribbed protrusions or both that run along the length of the fender unit from top to bottom of the fender unit.
[00033] As per another aspect of the present embodiment, the lower portion of the fender unit supports one or more rear indicator lamps, by means of one or more rear indicator mounting provisions.
[00034] As per another aspect of the present embodiment, a cut out is provided on the inner wall of fender unit, which aids in dissipating heat and enables flow of air inside the fender unit from the front portion of the fender unit.
[00035] As per another aspect of the present subject matter the battery unit is located on a central longitudinal axis of the saddle type vehicle.
[00036] As per another aspect of the present subject matter the control unit is disposed substantially above the battery unit and substantially parallel to the central longitudinal axis of the vehicle.

[00048] Fig. 1a to Fig. 1b illustrates a partial side and perspective view of a rear portion of a saddle type vehicle 100 in accordance with an embodiment of the present invention. The saddle type vehicle 100 includes a frame assembly 115to support different parts of the saddle type vehicle 100. In an upper portion of the frame assembly 115, a handlebar assembly (not shown) is rotatably integrally connected to a steering shaft (not shown). The handlebar assembly is used to steer the saddle type vehicle 100 and is connected to a front wheel (not shown) through the steering shaft and a front fork assembly (not shown). An upper portion of the front wheel (not shown) is covered by a front fender (not shown) which prevents mud and water from getting deflected towards the steering shaft (not shown). Further, the front fork assembly is supported on the front fender by means of a brace fender (not shown).
[00049] A seat assembly 105 is placed above the side panel assembly 125, 150 (shown in Fig. 1b). The seat assembly 105 includes a front rider seating portion and a pillion rider seating portion. The pillion rider seating portion is placed on the rear part of the frame assembly 115, where the rear part of the frame assembly 115 is covered by the rear panel 120.
[00050] For the safety of the rider and in conformance with the traffic rules, on the rear portion of the two wheeled saddle type vehicle 100 a tail lamp 130 and rear indicator lamps 135 are provided on the rear portion of the rear panel 120. Above the rear panel 120 and behind the seat assembly 105 pillion handle 110 is provided for the pillion rider to grab.
[00051] The suspension systems are provided for comfortable steering of the two wheeled saddle type vehicle 100 on the road. A rear suspension system (not labeled), which is a hydraulic damped arrangement, is connected to the frame assembly 115. The rear suspension system comprises of at least one rear suspension preferably disposed centrally in the longitudinal mid plane of the saddle type vehicle 100. However, in a saddle type vehicle 100 with two rear suspensions, the same may be disposed on the left side and the right side respectively of the saddle type vehicle 100.
[00052] The first power source, for example the engine assembly (not shown) is mounted to a front lower portion of the frame assembly115 by means of an engine mounting bracket (not shown).
[00053] Further, a swing arm (not labeled) extending rearwards is swingably connected to a lower rear portion of the vehicle 100. The rear wheel 145 is rotatably supported at a rear end of the swing arm (not labeled). Power from the engine assembly is transmitted to the rear wheel 145 through a power drive mechanism, such as a drive chain, so as to drive and rotate the rear wheel 145.
[00054] A fender 140 for covering an upper side of the rear wheel 145 is mounted to a rear portion of the saddle type vehicle 100 to prevent mud and water splashed by the rotating rear wheel 145 from entering a muffler assembly (not shown), the engine assembly and other parts disposed close by. To enhance the overall aesthetics of the saddle type vehicle 100 and to prevent undesired foreign particles from entering parts of the saddle type vehicle 100, a plurality of rear covers (not labeled) is attached to a rear portion of the frame assembly 115.
[00055] Area below the seat assembly 105 and the fuel tank assembly (not shown) of the saddle type vehicle 100 is covered on both sides by a side panel RH 150 (shown in Fig. 1b) on right hand side and a side panel LH 125 on the right-hand side of the saddle type vehicle 100.
[00056] Fig. 2 illustrates a rear view of the rear portion of a saddle type vehicle 100 in accordance with an embodiment of the present invention. The present figure illustrates the rear portion of the saddle type vehicle 100 without a rear panel 120 (as shown in Fig. 1a and Fig. 1b). As shown in Figure 9, the fender unit 140 includes an upper portion of the fender unit, herein called as a fender upper 140a and a lower portion of the fender unit 140, herein called as a fender lower 140b. Since the present illustration illustrates the rear portion of the saddle type vehicle 100 without the rear panel 120 (as shown in Fig. 1a and Fig. 1b), therefore the present illustration exposes the fender upper 140a, which is usually hidden behind the rear panel 120. The fender lower 140b is usually an exposed portion without any cover, as in case of the fender upper 140a. The fender lower 140b of the fender unit 140, is used as a cover over the wheels (front or rear) of the saddle type vehicle 100 to prevent mud, sand and dust being thrown on to the vehicle body, the occupants and the pedestrians.
[00057] The fender upper 140a is supported by the frame assembly 115 on the rear portion adjoining the seat assembly 105 and is disposed between the side panel RH 150 and the side panel LH 125.The fender lower 140b supports one or more rear indicator lamps 135, by means of one or more rear indicator mounting provisions (135a, 135b). The one or more rear indicator mounting provisions (135a, 135b) being disposed on the either side of the fender unit 140 along a horizontal plane AA’ (shown in Fig. 3) of the fender lower 140b of the fender unit 140.
[00058] As per an alternate embodiment the fender unit 140 at least partially extends rearwardly of a top portion of a rear wheel 145 of the saddle type vehicle 100, such that at least a portion of the rear wheel 145 is covered by the fender unit 140.
[00059] As per an alternate embodiment the fender upper 140a being configured to mount one or more electrical components.
[00060] Fig. 3 to Fig. 4 illustrate a rear view and a rear perspective view of the fender unit 140 of a saddle type vehicle 100, when viewed from the rear of the saddle type vehicle 100 in accordance with an embodiment of the present invention. As per the shown illustrations, the fender unit 140 includes a fender upper 140a and a fender lower 140b integrated as a single piece construction. The fender unit 140 is divided into the fender upper 140a and the fender lower 140b by a middle horizontal plane XX’. The fender upper 140a further includes a first portion a, and a second portion b.
[00061] The first portion a of the fender upper 140a includes a region Y (shown by horizontal 1st dotted rectangle in Fig. 3). The second portion b of the fender upper 140a includes a region Y’ (shown by horizontal 2nd dotted rectangle in Fig. 3) disposed above the 1st dotted rectangle. The second portion b of the fender upper 140a includes a region M (shown by horizontal dotted rectangle in Fig. 4).
[00062] The region Y has an approximately rectangular region or receptacle present at substantially center position of the fender upper 140a that includes a dedicated housing for the mounting of a battery unit 305. The region Y’ is located substantially above the region Y of the fender upper 140a of the rear panel 120. The region Y’ is a dedicated housing for the disposal of a control unit 300, for example an ECU unit or an ISG control unit, which is disposed substantially parallel to the horizontal plane XX’’. The ECU unit is mounted on the fender upper 140a and oriented horizontally overhanging from the region Y’ of the fender upper 104a. The control unit 300 is attached by suitable means such as a fastener 300a for ECU mounting. This configuration of the disposal of the battery unit 305 in the region Y and the disposal of the control unit 300 in the region Y’ aids in reduction of live wire and wiring harness length, because of the proximity of the region Y and region Y’ while still achieving a safe, reliable and secure design. Since, the battery unit 305 and the control unit 300 generate considerable amount of heat during functioning therefore the present configuration allows both units to be placed in proximity of each other but disposed in separate housings having separate well defined substantially orthogonal regions (Y, Y’).
[00063] As per another embodiment, the control unit 300 and the battery unit 305 are disposed in separate regions on the fender unit upper 140a. Such separation in layout allows both electronic components to function properly without affecting each other functions.
[00064] As per an alternate embodiment the Control unit 300 is disposed such that ports of the ISG control unit are facing downwardly towards the battery unit 305 of the saddle type vehicle 100. This downward configuration further aids in reduction of live wire and wiring harness length and enables ease of assembly and ease of access for servicing the ISG control unit.
[00065] As per another alternate embodiment, the control unit 300 and the battery unit 305 are disposed symmetrically about the vehicle longitudinal axis.
[00066] As per another alternate embodiment, the control unit 300 is inclinedly oriented with respect to a vehicle longitudinal axis.
[00067] As per another alternate embodiment the control unit 300 is a battery control unit.
[00068] As per another alternate embodiment the control unit 300 is a ISG control unit.
