BACKGROUND 5
[0002] Generally, in motor vehicles with an internal combustion (IC) engine, power/torque is produced by combustion of air-fuel mixture. The air-fuel mixture is provided from an intake system and a fuel system. In order to start the IC engine, typically, a starter motor is used along with the IC engine for performing starting operation of the IC engine. Typically, the starter motor is mounted to a crankcase 10
of the IC engine. The starter motor is connected to a crankshaft of the IC engine through a gear system, which may include Bendix gear or the like. Additionally, a magneto is provided along with the IC engine, and the magneto is used as a generator. The magneto is used for charging an on-board battery or to power electrical equipment of the motor vehicle. In the recent times, an electrical machine, 15
which can operate both as a starter and a generator has gained prominence for use in IC engines. BRIEF DESCRIPTION OF THE DRAWINGS [0003] The detailed description is explained with reference to an embodiment of a two-wheeled saddle-ride motor vehicle along with the accompanying figures. The 20

[00010] Fig. 2 (f) illustrates a side perspective of a portion of a motor vehicle, in accordance with an embodiment of the present subject matter. [00011] Fig. 2 (g) illustrates another perspective view of a portion of the motor 10
vehicle, in accordance with an embodiment of the present subject matter. [00012] Fig. 2 (h) illustrates an enlarged view of an integrated-electrical casing, in accordance with an embodiment of the present subject matter. DETAILED DESCRIPTION [00013] Generally, in saddle-ride motor vehicles, the IC engine may include a 15
carburetor or a fuel injector, an ignition system, a valve timing system etc., which may be electronically operated. Further, an electrical machine is used along with the IC engine and the electrical machine is capable of operating as both a starter and a generator. The electrical machine needs to be electronically controlled to work in starter mode, generator mode and other operating conditions. Further, the 20
vehicle includes many other electrical systems like a battery, which is an energy storage device, used to charge and operate the electrical machine. [00014] In order to perform control operation of the electrical/electronic systems of the motor vehicle, a large sized controller may be required. Typically, in a saddle ride motor vehicle, style panels are mounted to a frame and hence, are closer to the 25
frame. Accommodation of the large sized controller is a major challenge considering compactness of the motor vehicles like saddle-ride vehicles. In the art certain attempts were made, to use two controllers instead of one large controller. However, accommodation of the two controllers in the motor vehicle is still a challenge. 30

4
[00015] For example, in certain designs, the controllers are disposed in a portion of the motor vehicle, which is with a zone of interaction of the rider. The zone of interaction includes a region where the rider sits or puts his/her legs. Disposition of the controllers in such a location, say below a seat, may require increasing gap between the style panels disposed near the seat or may result in compromising of 5
cushioning provided on the seat, which affects riding comfort and usage convenience. In order to retaining the cushioning, a seat height may have to be increased, this increases seating height thereby adversely affecting ground-reach for the rider. Moreover, the controller that operates the electrical machine gets heated up and disposing the controller rearward to IC engine, in the rider interaction 10
zone, further increases its temperature since most of the hot air flowing from the IC engine is directed towards controller. Excessive heating of the controller affects its operational performance and also creates discomfort to the rider, due to the heat dissipation. Further, to create a separate air flow or for forced cooling for the controller, additional space has to be created in the vicinity of the controller, which 15
again is in the zone of interaction of the rider. [00016] In yet certain other designs known in the art, a controller for operating the electrical machine is disposed ahead of a head tube of frame. This is done for natural cooling of the controller. Typically, the controller may be supported on a steering assembly or may be disposed ahead of a steering assembly. However, electrical 20
wiring has to pass by the head tube and reach the controller disposed ahead of the head tube. In such a configuration, the electrical wiring is subject to undue stress due to the steering operation. This may result in failure of the electrical wiring with time. Failure of operation of the controller may even affect the startability of the vehicle. Moreover, it is difficult to access the controller in such a configuration for 25
diagnosis during servicing or the like. Typically, a head lamp assembly, turn signal indicators and other electrical components are disposed ahead of the head tube. The region in vicinity of the head lamp assembly is populated and comprises corresponding wiring harness. Thus, ease of access and routing of electrical wiring for the controller becomes a challenge. 30

5
[00017] Hence, the present subject matter provides a motor vehicle that is aimed at addressing the aforementioned and other problems in the prior art. [00018] The motor vehicle comprises of a frame assembly. The frame assembly is configured to support a power unit. The power unit can be an internal combustion engine, an electric motor, or a combination of both. The motor vehicle includes an 5
electrical machine, which is either functionally mounted to the power unit or is acting as a prime mover of the motor vehicle. In one implementation, the electrical machine is connected to a crankshaft of the power unit. An electronic-controller, which is configured to control operation of the electrical machine, is provided. The electronic-controller is disposed ahead of the power unit and rearward to a steering 10
axis of the motor vehicle. [00019] The electronic-controller is disposed away from flow of hot air, which would be flowing from the power unit. Further, the electronic-controller is disposed rearward to the steering axis, whereby any electrical wiring related to the electroniccontroller is not extended ahead of the steering axis but is configured rearwards of 15
the steering axis. The electronic-controller is disposed away from a zone of interaction of the rider, whereby utility space below a seat assembly is maximised and sufficient cushioning can be provided for the seat assembly without increasing the seat height. [00020] In one embodiment, the frame assembly comprises a head tube and a first 20
member. The head tube is disposed in a front portion of the motor vehicle and the steering axis is defined about the head tube. The first member extends rearward from the head tube, and the first member undergoes a first bend and subsequent extending downward. In one embodiment, the power unit is fixedly mounted to the frame assembly and is supported by the first member. 25
[00021] Further, the electronic-controller is at least partially disposed within a firstsector region. The first-sector region being a region having a center when projected overlaps with the head tube. A radius of the first-sector region is equal to a first length, the first length being one of a length of the first member (taken between the head tube and the first bend) or a length of a second member. The electronic-30

6
controller disposed rearward to steering axis is at least partially accommodated within the first-sector region. [00022] In one embodiment, the frame assembly comprises a second member extending obliquely downward from a rear portion of the head tube. The electroniccontroller is disposed within the first-sector region and the first sector region 5
extends substantially between the first member and the second member of the frame assembly. Thus, the electronic-controller is securely disposed within the first-sector region and is guarded from the first member and second member of the frame assembly. Moreover, wiring harness towards the electronic-controller can be done securely along the first member or the second member. 10
[00023] In one embodiment, the first-sector region comprises a first sector angle that is in range of 15-85 degrees. [00024] In one embodiment, the electronic-controller is configured to operate one or more sub-system of the power unit, which is in addition to operation of the electrical machine. The first sector angle of the first-sector region enables 15
accommodation of a large controller without affecting zone of interaction of the rider. [00025] In one embodiment, the motor vehicle comprises a power unit-controller, which is independent of the electronic-controller. The power unit-controller is configured to operate one or more sub-systems of the power unit. The power unit-20
controller is also disposed within the first sector region. In case of two controller viz. electronic-controller & power unit-controller, both the controllers are disposed within the first-sector region. [00026] In one embodiment, the electronic-controller, the power unit-controller, the electrical machine, and an auxiliary power source (which gets functionally 25
connected to the electronic-controller, the power unit-controller, and the electrical machine) are at least partially disposed within the first-sector region. All the components that are electrically connected to each other are disposed within the first length/radius of the first-sector region being formed rearward of the steering axis. 30

7
[00027] In one embodiment, the motor vehicle comprises an integrated-electrical casing, which is configured to support an auxiliary power source and a power unitcontroller. The auxiliary power source and the power unit-controller are functionally connected to each other and further, functionally connected to the electronic-controller. Length of wiring harness for connection between the auxiliary 5
power source and the power unit-controller is kept minimal. Also, electrical connection from the electronic-controller to the auxiliary power source and the power unit-controller is kept optimal as the auxiliary power source and the power unit-controller are disposed in proximity. [00028] In one embodiment, the frame assembly comprises a steering-reinforcing 10
member. The steering-reinforcing member, which is part of the frame assembly, is secured to the head tube, a first member, and a second member of the frame assembly. The electronic-controller is disposed adjoining the steering-reinforcing member on one of a lateral side thereof. In one implementation, the steeringreinforcing member comprises flat outer lateral surface in order to accommodate 15
the electronic-controller adjoiningly threat. Need for an additional mounting boot is eliminated. [00029] In one embodiment, the electronic-controller is enclosed by a shroud assembly, which forms part of a fuel tank assembly of the motor vehicle. In one implementation, the shroud assembly is an external shell. The electronic-controller 20
is securely accommodated within the shroud assembly thereby protecting the electronic-controller form environmental parameters and from any impact. The shroud assembly comprises a first front member being disposed ahead of the electronic-controller and forming a front portion of the shroud assembly. [00030] In one embodiment, the first front member is provided with plurality of air 25
inlets to enable flow of air towards a power unit for cooling. The first front member defines an independent air inlet to enable flow of air towards the electroniccontroller. Thus, the air flow towards the power unit is undisturbed. [00031] In one embodiment, the first front member is detachable from the shroud assembly. The first front member, in a detached condition, provides access to the 30
electronic-controller for diagnosis during servicing.

8
[00032] In one embodiment, the shroud assembly encloses a duct, which is configured to have an inlet aligned with an air inlet of the first front member. The duct comprises an outlet for directing air towards a power unit. In one implementation, the duct is a passage and the air inlet of the first front member may include louvers, air guides, perforations etc. 5
[00033] In one implementation, the duct is disposed adjacent to the electroniccontroller and the duct overlaps with at least a portion of the electronic-controller in a side view of the motor vehicle. Thus, air flow can simultaneously enter the duct and towards the electronic-controller. [00034] In one embodiment, the electronic-controller comprises a first-arm, which 10
is provided on a top portion. The electronic-controller enables suspending of the electronic-controller from the steering-reinforcing member and for securing thereto. In one implementation, as second-arm is provided at a bottom portion of the electronic-controller for securing it to the second-member of the frame assembly for secure mounting. 15
[00035] In one embodiment, the electronic-controller comprises a plurality of cooling fins, which are disposed in a vertical orientation, and the cooling fins are provided on an outward facing side of the electronic-controller. The cooling fins, which are disposed away from an air entry portion are longer when compared to the cooling fins that are in proximity thereof for effective cooling across the electronic-20
controller. [00036] In one embodiment, the electronic-controller is disposed such that one of two large surface areas (surface not having cooling fins) is abutting the steeringreinforcing surface thereby occupying less spae in width direction of the motor vehicle. This ensures that there no blockage of air flow towards other parts. 25
[00037] In one embodiment, the electrical machine is functionally mounted to the power unit and the power unit being an internal combustion engine. The electrical machine is configured to operate as a starter of the power unit and it operates as a generator to charge an auxiliary power source when the power unit is in running condition. 30

9
[00038] In one embodiment, the electrical machine acts as a prime mover of the motor vehicle thereby acting a significant part of the power unit, which may further include transmission and other systems. The electrical machine acting as the prime mover drives the motor vehicle. [00039] Arrows wherever provided in the top right corner in the drawings depicts 5

The cylinder portion 121 may include a cylinder head, a cylinder block and a cylinder head-cover (not marked). Further, an intake-manifold 5
222 (as shown in Fig. 2 (b)) gets connected to the cylinder portion 121 of the power unit 120 and a fuel-injector (not marked) may be mounted to the intake-manifold 222. In one implementation, the intake-manifold 222 is having a straight path. In another implementation, the intake-manifold 222 is having a curved path. In the depicted embodiment, the power unit 120 is a forwardly included type, which 10
implies , a cylinder axis C-C’ of the power unit 120 is forwardly inclined. The effect of heat dissipated from the power unit 120 is minimal to negligible on the electronic-controller 205 as it is disposed away and ahead of the power unit 120. In one embodiment, the electronic-controller itself can be configured to control the one or more sub-system of the power unit 120. However, in the depicted 15
embodiment, the motor vehicle 100 comprises of a power unit-controller 210 that is configured to control and operate the one or more sub-systems of the power unit 120 and thereby control operation of the power unit 120. For example, some of the operations include fuel injection timing, fuel injection start time, amount of fuel to be injected, spark ignition timing, and may include feedback control from data 20
received from a lambda sensor, or an on-board diagnostics (OBD) system. [00047] The electronic-controller 205 is configured to enable charging of the auxiliary power source 215 when the electrical machine 125 is operating in generator mode. In one embodiment, the auxiliary power source 215 is mounted to the first member 135, and is disposed subsequent to the first bend 136, downward 25
thereof. Further, the auxiliary power source 215 is disposed at an offset from a centre, in a width wise direction or lateral direction RH-LH, of the vehicle 100. The auxiliary power source 215 is disposed at the offset in order to enable routing of the intake-manifold 222 (shown in Fig 2 (b)). The intake-manifold 222 and the auxiliary power source 215 are disposed on either side effectively configuring it 30

[00050] Further, the electronic-controller 205 is disposed ahead of the power unit 120, which is substantially disposed below the fuel tank assembly 164 (shown in Fig. 1). The electronic-controller 205, which is disposed rearward to the steering 25
axis S-S’ receives air for natural cooling and at the same time has minimal effect of heat dissipation from the power unit 100. During operation of the motor vehicle 100, the direction of flow of air would be in front to rear direction FW->RW and the hot air from the power unit 120 flows in a rearward direction. [00051] Further, the electronic-controller 205 is at least partially disposed within a 30

Further, the first-sector region 230 comprises of a first radius 232 equal to a first length, which is taken along the first member 135 till the first bend 136. In other embodiment, the first length is a length of the second member 140. Further, as per 5
the depicted embodiment, the power unit-controller 210 is at least partially disposed within the first-sector region 230. In other words, the first-sector region overlaps with the electronic-controller 205. [00052] Further, the power unit-controller 210 is also at least partially disposed within the first-sector region 230. Further, the first-sector region 230 overlaps with 10
the electrical machine 125 and the auxiliary power source 215, at least partially. The electronic-controller 205, the power unit-controller 210, the electrical machine 125 and the auxiliary power source 215 are each at least partially disposed within the first-sector region 230, which spreads between the first member 135 and the second member 140.

Preferably, the first-sector angle is the range of 15-85 degrees. These aforementioned components are in proximity enabling ease of electrical connections therebetween. A wiring harness is routed about the first 20
member 135 and the second member 140 between two or more components with ease. For example, wiring harness 240 from the electronic-controller 205 is routed along the first member 135 towards the auxiliary power source 215, the power unitcontroller 210 and the electrical machine 125 securely therealong. Further, in one embodiment, the motor vehicle 100 comprises an integrated-electrical casing 245, 25
which is configured to support the auxiliary power source 215 and the power unitcontroller 210.
