Description

A SADDLE-RIDE TYPE MOTOR VEHICLE

TECHNICAL FIELD

[0001] The present subject matter relates to a straddle-type vehicle. More particularly but not exclusively, to vehicle layout of the straddle-type vehicle for packaging of one or more control units in the vehicle.

BACKGROUND

[0002] In conventional vehicles, one or more control units are packaged on frame assembly of the vehicle. The packaging of the one or more control units are achieved by mounting the one or more control units by means of mounting brackets. The mounting brackets are welded on the frame assembly. The frame assembly consisting of mounting brackets is usually covered by plurality of body panels made of plastic or metals and the body panels are fastened at all intended joints. The plurality of body panels should be configured such that they can completely cover the frame along with the mounting brackets as desired, in the vehicle. Conventionally, the one or more control units along with their mounting brackets are disposed either on right side or left side of the vehicle.

DETAILED DESCRIPTION OF THE INVENTION

[00010] In conventional vehicles, in a known art, the mounting locations for one or more controllers, in particular, a controller to control generator, generally known as an ISG controller includes mounting of the ISG controller on one side of a main frame of a frame assembly of the vehicle. In the vehicle, the ISG controller lies between the side of the main frame and a side panel that covers the side of the main frame. Generally, as known in the art, the ISG controller is bigger in size and rectangular in shape. The ISG controller with bigger dimensions requires pre-defined space, wherein the space is capable of accommodating the ISG controller that is larger in size. To achieve the same, the shape and size of the side panel may undergo changes as required to facilitate packaging of the ISG controller. The requirement of change in the side panel, that is able to cover the length and width of the bigger ISG controller arises which can adversely impact the compact packaging and width of the vehicle. Further, in order to prevent changes in the shape and size of body panels of the vehicle, the size of the ISG controller has to be compromised, in turn, the requirement of incorporating the ISG controller of higher configuration has to be foregone which is undesirable.

[00011] Further, the ISG controller is mounted on the frame assembly. The mounting of the ISG controller on the frame assembly is facilitated by one or more brackets welded on the frame assembly. If mounted on the frame assembly, then typically the mounting is carried out only at one portion of the ISG. The mounting, wherein only a portion of the ISG controller is configured for mounting the ISG, facilitates usage of smaller brackets as mounting means and thereby eliminate undesirable bigger brackets. The bigger brackets require a bigger welded joint with the frame assembly. However, the conventional mounting means by means of a portion of the SIG controller, being used to mount the ISG controller on the frame assembly causes overhang of the ISG controller. The overhang produces unwanted vibrations that may adversely affect stable functionality of the ISG controller.

[00012] Further, the mounting of the ISG controller on any other portion of the frame assembly may cause compromise in utility space available for storage, in addition to compromise in storage space of a fuel tank assembly.

[00013] For example, in sleeker vehicles, a rear portion has shape that is comparatively compact. In such sleeker vehicles, the space available between the side panels and portion of the frame assembly is almost negligible. In this particular type of compact layout vehicle, the mounting of the ISG controller may have to be shifted towards a vehicle center line. The presence of the ISG controller closer to the vehicle center line has undesirable impact on the utility space and also adds to the requirement of modification in shape of a utility box to accordingly match with the profile of the ISG controller exists.

[00014] The ISG controller comprises of plurality pins to connect with one or more couplers and wiring harness from systems like a power source, an auxiliary energy source, etc.

[00015] The mounting of the ISG controller and the location of the ISG controller in the vehicle plays an important role. The orientation of the one or more couplers should be such that the accessibility of the one or more couplers is hassle free for ease of service, diagnostics, and maintenance. The accessibility of the one or more couplers is critical for service as well as wiring harness routing. However, in sleeker vehicles, as explained above, the one or more couplers, being disposed closer to the vehicle center plane and being away from the external surface of the vehicle body, cannot be accessed easily.

[00016] Further, the location of the ISG controller in the vehicle should be such that the vehicle layout includes space for wiring harness that connects between the ISG controller and the systems like a power source, an auxiliary energy source, etc. The vehicle layout should be such that a various size of wiring harness can be accommodated. Additionally, the distribution of the wiring harness for various vehicle aggregates from the front most headlamp unit to the tail lamp unit tend to span over the length and breadth of the entire vehicle volume thereby leading to need of configuring plurality of wiring harness in the vehicle which can be in order of minimum 3 sets of wiring harness or more. Thus, there exists as challenge of minimizing the wiring harness sets as well as routing them in a hassle-free manner so that they do not entangle with each other, are easy for assembly, service, fault detection, as well as avoid any undesirable electromagnetic interference. The space for wiring harness available in the vehicle layout is an important factor to be considered. The wiring harness in the vehicle layout should be routed such that all the clearance requirements including non-interference with other parts in the vehicle and other sub systems is achieved.

[00017] The interference of the wiring harness with other sub-systems in the vehicle may cause undesired vibrations and loosening of various wires/cables involved in the wiring harness. Further, there might be chance of occurrence of short circuit due to constant pressure exhibited on the wiring harness through physical and/ or electromagnetic interference with the sub-systems.

[00018] Unwanted vibrations also directly affect the vehicle drivability condition.

[00019] The location of the ISG controller in the vehicle also should be such that the ISG controller is not affected by heat emanated by the sub-systems and surrounding parts that may adversely affect the performance of the ISG controller. Further, the

4 ISG controller should not be affected due to entry of water to avoid circuit damages due to short circuiting, etc.

[00020] The ISG controller unit mounting should be stable to avoid any unwanted vibrations which directly effects the vehicle drivability condition.

[00021] Ideally, the two wheeled vehicles should be standing upright. However, there is always small amount of unbalanced weight on either the right-hand side or on the left-hand side of the vehicle. Because of which, the two- wheeled vehicle tends to lean either on the right-hand side or the left-hand side depending on the unbalanced weight on that respective side of the vehicle. The location and mounting of the ISG controller in the vehicle should be such that the vehicle riding is not affected due to any such imbalance.

[00022] Therefore, there is a need for an improved layout and mounting configuration of an ISG controller which provides stable mounting of the ISG controller along with better accessibility location for the service in the vehicle layout that does not affect balance of the vehicle while overcoming all problems cited above and other problems of known art.

[00023] For vehicles with integrated starter generator (ISG) system, controllers are used to control the starter generator for electric start and charging application. The ISG controllers are complex for their functionality of being able to handle high current for the purpose of starting ISG. The ISG controllers for their complex functionality, are typically large in size. Due to its larger form factor and limited space in straddle type vehicle mounting the electronic component, with preference for the electronic component to be located closer to auxiliary energy sources in the vehicle, packaging a single integral controller as an electronic component closer to the battery is difficult wherein the battery is typically located behind the engine assembly in straddle type vehicles. In addition, any failure on one of the components leads to replacement of entire unit which will also be at higher cost to the consumer and the manufacturers. Further, locating such electrical/electronic components in the known areas such as behind the engine and in the vicinity of the battery also suppress the availability of natural air during the vehicle running condition, which will excessively heat up the electrical component and largely impede the functioning of such electronic devices.

[00024] Thus, there is a need to configure a vehicle layout with packaging of the electronic devices in layouts that has the above described limitations, while still being configure with an optimal mounting location, which overcomes the problem with respect to cooling of the electronic device without impacting on other parameters such as wiring harness length, wiring harness routing, and vehicle handling and other problems of know art.

[00025] Further, as per known art, the engine assembly is typically in an upright position. The ISG controller is placed behind an engine cylinder which is enclosed with a housing and a dedicated duct is provided in the housing for the purpose of air circulation. As the engine assembly is the power house of the vehicle, huge amount of heat is dissipated on its surface. As a result of which, placement of the ISG controller in the area surrounding the engine assembly requires immense amount of air circulation. Inadequate air circulation to the ISG controller could lead to heating of the controller thereby adversely affecting controller performance. The excessive heating of the controller could lead to internal component failure, if proper cooling arrangement is not provided.

[00026] As per other known art, the straddle type vehicle has two controllers, one for controlling integrated starter generator and another controller for fuel injection. Configuring a single integrated controller requires larger space to be provided for packaging the same and in an area where air circulation is available for its operational efficiency and hence split controller configuration may be preferred. [00027] However, adapting the teachings of both the above-mentioned prior arts would still not enable a skilled person to solve the problems posed in front of him with respect to the existing vehicle layout. For instance, having two different controllers, i.e., one for controlling the generator and another for controlling the EFI and accommodating in the vicinity of the battery would still not solve the problem with respect to cooling, wire routing and vehicle handling.

[00028] Moreover, disposing the ISG controller behind the engine as taught by the know arts, would still continue to impact the cooling, ease of assembly and serviceability of the control unit.

[00029] Similarly, in yet another known art, mounting a control unit, in particular, an ABS control unit in front of an engine cylinder head and located behind the fuel tank, i.e., behind a vertical plane passing along the front end of the fuel tank is disposed. Further, the control unit in the above said known art, is located above the exhaust pipe and below an upper surface of the engine. Thus, the location being taught by the known art would still not enable a skilled person to overcome the problem with respect to the cooling of the controller as the presence of engine cylinder block and the exhaust pipe in its vicinity would only increase the temperature around the control unit. Further, some know art teach about covering the control unit with a cover member for protecting the control unit when it is placed in such a location which adds to number of parts and impede the cooling of the controller.

[00030] Thus, it is an objective of the present invention to overcome the above drawbacks of the prior arts and also eliminate the need for any additional component such as cover.

[00031] The present subject matter provides a layout configuration for disposing the electronic device. As per the present invention, the layout of the vehicle is configured to dispose electronic device ahead of the fuel tank above the cylinder block thereby allowing ease of access, low operating temperature as well as ease of routing high power cables.

[00032] According to the present subject-matter, the electronic device is located in front of the engine assembly. The electronic device is mounted and located such that it is placed forwardly to a frame member as well as forward to the fuel tank assembly. Thus, the electronic component is located adequately away from the heat generating sources in the vehicle.

[00033] According to another embodiment of the present invention, the electronic component is placed at a distance farther from the exhaust pipe where in a pre-defined gap between the electronic component and the exhaust pipe is configured to accommodate a mechanism to force cool the engine assembly. In the proposed layout, the electronic component is disposed farther from the heat source and placed positioned in the front region of the vehicle such that natural air flow is abundantly available and the location of the electronic component is not an obstruction for the continuous flow of atmospheric air to the engine assembly. In addition, for vehicles with heat exchangers for the engine assembly, the mounting location can be standardized between the electronic component and the heat exchangers thereby improving the assembly and eventually saving the assembly time.

[00034] The further explanation to the above said advantages of the present invention is provided in the detailed description of the figures below. The present subject matter is further described with reference to accompanying figures. It should be noted that the description and figures merely illustrate principles of the present subject matter. Various arrangements may be devised that, although not explicitly described or shown herein, encompass the principles of the present subject matter. Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof. [00035] Figure 1 illustrates a right-side view of a two-wheeled vehicle, for example, a motorcycle 100 according to an embodiment. The motorcycle 100 according to an embodiment includes a front wheel 101 steered by a handlebar 102 and a rear wheel 103 supported by a swing arm 104. Steering assembly parts including the handlebar 102 and the front wheel 101 are supported for pivotal steering operation on a head pipe 105 at the front end of the vehicle frame 106. A seat assembly 110 for a driver and a pillion is placed rearward to a fuel tank assembly 114 in the exemplary vehicle shown. The fuel tank assembly 114 is supported on a rearwardly extending portion of the frame structure 106. An engine assembly 113 is disposed below the fuel tank 114. A front fender 111 is provided above the front wheel 101 to avoid the said vehicle and its occupants from being splashed with mud. Likewise, a rear fender 112 is placed above the rear wheel 103, and to the outer side in the radial direction of rear wheel 103. Rear fender 112 inhibits rainwater or the like from being thrown up by rear wheel 103. The swing arm 104 along with a shock absorber 109 is supported at a front portion thereof for pivotal motion and upward and downward rocking motion on the rear side of a lower portion of the vehicle frame 106.

[00036] The vehicle frame structure 106 includes a head pipe 105, a pair of left and right main frames 107. The head pipe 105 is positioned at a front-end portion of the vehicle frame 106. The main frames 107 extend in a leftwar dly and rightwar dly branching state obliquely downwardly rearwardly from a lower portion of the head pipe 105.

[00037] Figure 2 illustrates a right-side view of the straddle-type, exemplary motorcycle. According to an embodiment of the present invention, an electronic component 202 is mounted in front of and forwardly to the engine assembly 113. The engine assembly 113 includes a cylinder block 113a and a cylinder head 113b. The cylinder head 113b is disposed above the cylinder block 113a in the engine assembly 113. The cylinder head 113b is comprising at least one input port and at least one exhaust port. In particular, the electronic component 202 is located above the cylinder block 113a, such that when viewed from the front of the vehicle, the electronic component 202 would not block the passage of traversing atmospheric air towards the cylinder block 113a of the engine assembly. In particular, the abundance of the atmospheric air around the at least one exhaust ports in the engine assembly is still maintained without any obstruction by configuring the electronic component 202 according to the proposed location.

[00038] According to an embodiment of the present subject matter, the optimal cooling from the natural air directed towards the electronic component 202 during the vehicle running condition is obtained due to the proposed mounting of the electronic device 202. This optimal layout configuration isolates the electronic component 202 from the engine assembly 113, especially the high temperature zones of the engine assembly 113 such as the exhaust pipe, cylinder head etc.

[00039] The optimal layout design, which ensures that the electronic component 202 does not act as a hurdle for the passage of natural air towards the engine assembly 113 and the availability of cool air for the heat exchanger, that is typically placed in front of the engine assembly 113, is achieved.

[00040] The layout as per the present invention does not adversely affect the vehicle handling, for example, locating the electronic component 202 optimally disposed along a central longitudinal axis of the vehicle, and above the heat exchanger 203 and not offset to any of the sides, ensures that the vehicle handling is improved.

[00041] The present invention, proposes a mounting location for the electronic device, which can be an ISG controller, or an integrated generator cum engine controller, or a switching unit of a controller.

[00042] According to an embodiment of the present invention, one or more energy sources 207 for powering one or more electrical components and other components in the vehicle is disposed below the seat assembly 110. [00043] Figure 3 illustrates a left side view of the straddle type vehicle. According to an embodiment of the present invention, a heat exchanger 203 and the electronic component 202 are placed in front of the cylinder head 113b and below the fuel tank assembly 114 of the vehicle.

[00044] Accordingly, the electronic component 202 is mounted in front of cylinder head 113b, the heat exchanger 203 is packaged in a horizontal manner below the electronic component 202 and above the exhaust pipe 206. The pre-defined space in between above the muffler 206 and the frame assembly (not shown) is configured for packaging both the electronic component 202 and the heat exchanger 203. The layout so invented for mounting the electronic component 202 above the cylinder block 113a and above the heat exchanger 203 ensures that the electronic component 202 does not interfere with the vehicular parts such as the front fender (111 shown in figure 1) in vehicle riding conditions such as a full bump condition.

[00045] The proposed layout of electronic component 202 is in the high air flow zone of vehicle 100, hence ambient operating temperature is lower, resulting in higher efficiency of operation for the electronic component 202.

[00046] The electronic component 202 is exposed from the front side of the vehicle 100 and thus no additional cover is required for thermal isolation from any other heat source of the vehicle. Additionally, the present layout provides ease of assembly, dismantling, diagnostics and service.

[00047] The electronic component 202 is mounted away from the rider’s reach while riding that improves the rider comfort due to less exposure of rider to heat dissipating components.

[00048] Figure 4 illustrates a front view of the straddle type vehicle. According to an embodiment of the present invention, in order to facilitate heat exchanger 203. mounting below the electronic component 202, the first wiring harness 202w from the electronic component are drawn perpendicular to the electronic component 202,

11 along a side wise direction, towards left and right side when viewed from the vehicle front direction. The side wise routing of the first wiring harness 202w enables reduced tension in the wires due to minimum bending and curving and in addition, improves aesthetics of the vehicle. Further, the routing of cables in the first wiring harness 202w, like the high-power cable from the side of the electronic component 202 towards a the starter generator machine (not shown) is made shortest in terms of length of the cables, by having the wires out of one or more couplers as well as the couplers of the electronic component 202 along the same side as that of the starter generator machine. For instance, if the starter generator machine is disposed on a left side of the vehicle, then the wires out of the one or more couplers of the electronic component 202 are also oriented towards the left side. Additionally as per an aspect of the present invention, the routing of the first wiring harness 202w is carried along the down tube of the vehicle without interfering with other low power cables.

[00049] According to an embodiment of the present subject matter, the electronic component 202 and the heat exchanger 203 are sandwich mounted at one or more of the mounting positions 205 thereby reducing the number of components used for mounting and the number of operations required to assemble various components.

[00050] According to an embodiment of the present subject matter, the electronic component 202 is disposed such that an axial axis passing through the center of the electronic component 202 is perpendicular to the vehicle longitudinal plane passing centrally through the vehicle in a front-rear direction. Both the electronic component 202 and the heat exchanger 203 are extending in a vehicle width wise direction along a vehicle width axis R-L.

[00051] In another embodiment, the heat exchanger 203 is disposed substantially vertical and said electronic component 202 is disposed horizontally extending in a vehicle width-wise direction RL. [00052] Figure 5 illustrates a right-side view of a front portion of the straddle type vehicle. According to an embodiment of the present invention, a first vertical plane VP1 containing the electronic component 202 is disposed substantially forwardly of a second vertical plane VP2 containing the heat exchanger 203 when seen from a side of the vehicle 100. The frame assembly consisting of the downwardly extending frame member 106a is configured such that a predefined space is formed for packaging of the electronic component 202 and the heat exchanger 203 in two different planes. However, the length of the vehicle is maintained within a short wheelbase by achieving the above said configuration. Further, the predefined space provides enough freedom for steering of the front wheel as well, without any obstruction from the electronic component 202 and the heat exchanger 203. Further, both electronic component 202 and the heat exchanger 203 are adequately isolated by the heat dissipated or emanated from each other.

[00053] Figure 6 illustrates a left side view of a front portion of the straddle type vehicle. According to an embodiment of the present invention, the electronic component 202 derives energy from one or more energy sources 207 and converts the energy to an alternating current for motoring the starter generator machine 201 and vice versa during generation of the supply during operation of the engine assembly 113. In the process of energy conversion, the electronic component 202 is expected to dissipate heat in the form of losses. Similarly, when the electronic component 202 consist of one or more switching devices for the purpose of fuel injection, tends to dissipate more heat. The electronic component 202 is connected to the starter generator machine 201 using the high-power cables 201c to handle high current passing through the wires and devices. The electronic component 202 is configured in such a way that the high-power cables 201c are connected from the engine assembly 113 using a downwardly extending frame member, which is the downwardly extending frame member 106a of the frame assembly. The one or more couplers of the electronic component 202 are located optimally as described earlier such that the

13 high-power cable 201c lengths are shorter and provide ease of routing. The electronic component 202 can also be a switching unit with its controller located at a different position for eg: below the fuel tank assembly, and above the engine assembly 113 as indicated in the present embodiment. The controller to control the fuel injection (not shown) can also be a separate controller from the electronic component 202.

[00054] The electronic component 202 is located in front of the engine assembly 113, which also generates heat during its operation and kept outside the fuel tank assembly (not shown) to expose the electronic component 202 to the natural atmospheric air during the forward operation of the engine assembly. The electronic component 202 is located above the exhaust port in the engine assembly 113 and depending on the functional requirement, an engine force cooling unit can be configured between the exhaust port and the electronic component 202. The location of electronic component 202 is farther away from exhaust port there by it can be positioned without an additional cover to prevent exposure to radiated heat and the electronic component 202 is kept at a position forward with respect to exhaust pipe as well.

[00055] Although the subject matter has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. It is to be understood that the aspects of the embodiments are not necessarily limited to the features described herein.
