DETAILED DESCRIPTION
[00012] In the following description numerous specific details are set forth to provide a thorough understanding of the embodiments. One skilled in the relevant art will recognize, however, that the techniques described herein can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring certain aspects.
[00013] Typically, a hand twist throttle is located on a handle bar. The hand twist throttle is coupled to a prime mover to control vehicle acceleration and speed through mechanical linkages & cables. With the advent of electronics, mechanical systems are given enhanced controllability, e.g., electronically controlled throttle cable actuation system. Importantly, in electronically controlled throttle cable actuation system there is no direct mechanical coupling between the hand twist throttle and prime mover. In other words, the mechanical linkages were replaced by actuators/motors and sensors or can also be referred as drive-by-wire systems.
[00014] Typically, the electronically controlled throttle cable actuation system includes a throttle position sensor. The throttle position sensor senses hand twist throttle rotation and provides signals to an ECU. The ECU produces a prime mover control commands. The prime mover control commands are transmitted to the prime mover. Conventionally, a pulley is attached to the hand twist throttle. The pulley transmits throttle rotation movement to another pulley attached to throttle position sensor, via a cable. However, in the typically used electronic throttle cable actuation system, current technique for connecting the throttle position sensor to the hand twist throttle presents several disadvantages. The shortcoming of known electronic throttle cable actuation system is evident when the hand twist throttle in the vehicles is put to heavy use owing to various road as well as traffic conditions with multiple cycles of rotations. It is observed that repetitive manual operation of hand twist throttle leads to slackness in the cable. The slackness in cable affects the prime mover responsiveness due to delay in throttle response. The throttle response is a measure of how quickly a prime mover, can increase its power in response to a user’s request for acceleration. Therefore, the delay in throttle response causes an unpleasant driving/riding experience. However, the above issue can be addressed by periodic replacement of cable which involves significant replacement costs for the user. Therefore, many users tend to compromise on throttle response by running vehicle with poor prime mover responsiveness to save related service and labor cost. Additionally, the excess slackness in cable reduces vehicle safety performance characteristic. More specifically, the delay in throttle return response can cause more throttle to be applied unintentionally. This can lead to serious accident. Especially, in peak slopes and other slippery conditions where a slight over-rotation of hand twist throttle can cause too much prime mover acceleration which in turn can cause a loss in traction and control of the vehicle.
[00015] In addition to above, cable exhibit severe deterioration caused by corrosion. The corrosion comes about by exposure to humid air. To combat such cable deterioration, cable is encapsulated within a conventional sheath thereto i.e., insulation, often made of polyethylene. This results in significant increase in weight of cable due to additional protective material. The increased weight requires the cable to use dedicated support structures to avoid flexing. Therefore, the conventional method involves a considerable number of compromises and is also costly since additional material and dedicated support structures are required. Further, throttle position sensor and other periphery parts suffer from poor durability, high cost of repair cum maintenance etc. One of the reasons for poor durability is due to direct exposure to different environmental and road conditions. As per known art dedicated covers are used to protect the throttle position sensor from different environmental and road conditions. However, use of dedicated cover increases part count and weight of the vehicle. Thus currently known techniques do not provide a reliable electronically controlled throttle cable actuation system which is light in weight, durable as well as cost effective. Therefore, there is a need to provide an improved electronically controlled throttle cable actuation system to overcome the above-stated problems, and other problems of known art.
[00016] To this end, it is an object of the invention to provide a cost effective and reliable cable tension adjustment mechanism.

[00033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[00034] Figure 1 illustrates a perspective view of a handle bar assembly (100), as per embodiment, in accordance with one example of the present subject matter. The handle bar assembly (100) includes a handle bar cover (101), and cover member (102). The handle bar cover (101) extends in a lateral left-right direction perpendicular to a direction of a vehicle travel such that its major dimension is disposed in a lateral direction of the vehicle. The handle bar cover (101) is configured to have mounting provisions where one or more switches (105) are disposed on the both ends of the handle bar cover (101). The switches (105) are placed apart such that it comes within the reach of a user. The handgrips (103) are disposed at the both the ends of the handle bar cover (101). The hand grips (103) are ergonomically designed and are elliptical in cross sectional shape providing better grip to the user while driving. The cover member (102) is provided below the handle bar cover (101). The cover member (102) is detachably secured to at least a portion of the handle bar cover (101). The cover member (102) covers wires which are routed on the inner side of the handle bar cover (101) e.g. connecting wires for switches (105) etc. An instrument cluster (104) to indicate plurality of information is ergonomically accommodated in the handle bar cover (101).
[00035] Figure 2 illustrates an exploded perspective view of the handle bar assembly (100), as per embodiment, in accordance with one example of the present invention. The handle bar cover (101) receives a portion of a throttle tube (201) which is guided from one side and a portion of gear shift tube (not shown) from the other side. In illustrated embodiment, a right side of the handle bar cover (101) has the throttle tube (201), covered with the handgrip (103) to provide better hand hold. A primary pulley (202) is detachably attached to one end of the throttle tube (201) using a lock pin (203). The primary pulley (202) is provided with a key hole (204). The key hole (204) is configured to receive a primary cable barrel (205) of a cable (206). The primary cable barrel (205) securely fits into the key hole (204). Further, stopping means (not shown) are provided in the handle bar cover (101) for limiting the rotational movement of primary pulley (202) in assembled condition.
[00036] Figure 3 illustrates a top view and a side cut section view across A-A’ axis of the handle bar assembly (100) with a localized perspective view of the throttle position sensor (304) attached to a secondary pulley (301), as per embodiment, in accordance with one example of the present invention. The cable (206) connects the primary pulley (202) to the secondary pulley (301). The secondary pulley (301) is configured to have key hole (302). The key hole (302) receives a secondary cable barrel (303) of the cable (206). The secondary cable barrel (303) of cable (206) securely fits into the key hole (302). The secondary pulley (301) is operatively connected to a throttle position sensor (304). The secondary pulley (301) is a spring loaded type pulley. The secondary pulley (301) continuously exerts a predetermined force tending to oppose the rotation of primary pulley (202). Therefore, rotation of throttle tube (201) to which primary pulley (202) is attached requires a predetermined force above predetermined spring force. In illustrated embodiment, the rotation of throttle tube (201) in counterclockwise direction (when seen from a right side view of the vehicle) from its neutral position pulls the cable (206) to rotate the secondary pulley (301). The throttle position sensor (304) senses the rotational movement of secondary pulley (301) and generates the predetermined input signal. The input signal from throttle position sensor (304) is received by Vehicle Control Unit (VCU) (not shown) through wired or wireless communication medium. The received predetermined input signal is processed by the Vehicle Control Unit (VCU) (not shown) to generate a predetermined output command to a prime mover. Further, release of throttle tube (201), thereby releases the cable (206) which is pulled in reverse direction (clockwise direction) by the secondary pulley (301) until throttle tube (201) is returned to its idle position. As per an aspect of the present invention, to achieve compact packaging of vehicle, minimise cable length and response lag, the throttle position sensor (304) is disposed inside the cover member (102) and in close proximity of the steering axis (not shown).
[00037] A housing (304A) of throttle position sensor (304) comprises a base portion (304B). The base portion (304B) is configured to have flanged type profile. one or more circular shaped openings (304C) are provided in the base portion of the housing (304A). The throttle position sensor (304) is detachably and adjustably attached to a mounting bracket (305) using attachment means (306)Importantly, the mounting bracket (305) is serving as an interface between a handlebar tube (307), and the throttle position sensor (304).
[00038] Figure 4 illustrates an exploded perspective view of the handle bar assembly (100) and a localized view of the mounting bracket (305) as per embodiment, in accordance with one example of the present invention. The mounting bracket (305) comprises of a first plate portion (305A) and a second plate portion (305B). The first plate portion (305A) and second plate portion (305B) are substantially perpendicular to each other. The first plate portion (305A) is configured to have at least one opening (401) of predetermined shape. The predetermined shape includes arc shaped slots of predetermined radius of curvature. In illustrated embodiment, two arc shaped slots (401A, 401B) are provided. The arc shaped slots (401A, 401B) are configured to receive the attachment means (306) to connect the throttle position sensor (304) to the mounting bracket (305). The attachment means (306) as per an embodiment includes at least one threaded bolt (306A) & nut (306C) and washer (306B). In illustrated embodiment, two threaded bolts (306A) & nuts (306C) and washers (306B) are provided. A threaded portion of bolts (306A) passes through arc shaped slots (401A, 401B) and circular shaped openings (304C) configured on the throttle position sensor (304) respectively to detachably attach the throttle position sensor (304) to the first plate portion (305A) of the mounting bracket (305). Precisely, the bolts (306A) are inserted through arc shaped slots (401A, 401B) in the first plate portion (305A) and through two circular shaped openings (304C) to receive the nuts (306C). The nuts (306C) are tightened up uniformly on the threaded portion of the bolts (306A) to secure the throttle position sensor (304) and first portion (305A) of mounting bracket together. The bolts (306A) are secured in place by suitable nuts (306C), which engage washers (306B) against the outer face of first plate portion (305A). The washers (306B) prevent the displacement of the bolts (306A). The bolts (306A) are seated in the aligned circular shaped openings (304C) and arc shaped slots (401A, 401B). Further, the second plate portion (305B) is provided with one or more aperture (402). In the illustrated embodiment, two apertures (402) are provided. Threaded fasteners (403) pass through the apertures (402) in the second plate portion (305B) to secure the mounting bracket (305) to the handlebar tube (307).
[00039] Figure 5 illustrates side views of handlebar assembly (100), where few parts are omitted from the figure and a localized view of bolts (306A) assembled in the mounting bracket (305) shows different adjustment position as per embodiment, in accordance with one example of the present invention. As shown in figure 5 (a), the bolts (306A) are at central non adjusted position. Therefore, to adjust the tension in cable (206), the bolts (306A) are loosened and displaced from central non adjusted position for angular adjustment of the throttle position sensor (304) through movement of bolts (306A) in respective arc shaped slots (401A, 401B) as shown in figure 5 (b) and (c).Importantly, the adjustment is about an axis of actuation (not shown) of the throttle position sensor (304). The two arc shaped slots (401A, 401B) comprises upper half arc shaped slot (401A) and a lower half arc shaped slot (401B). As shown in figure 5 (b), the movement of bolt (306A) occurs towards the handlebar tube (307) in upper half arc shaped slot (401A) and corresponding movement of bolt (306A) away from handlebar tube (307) in lower half arc shaped slot (401B). This rotates the throttle position sensor (304) along with the secondary pulley (301) as a single unit towards the handlebar tube (307). Thereby, eliminates the slackness in the cable (206) and improves response as well as feel of response. Further, as shown in figure 5(c), similar movement of bolt (306A) occurs away from the handlebar tube (307) in upper half arc shaped slot (401A) and corresponding movement of bolt (306A) towards handlebar tube (307) in lower half arc shaped slot (401B). This rotates the throttle position sensor (304) along with secondary pulley (301) as a single unit away from the handlebar tube (307). Thereby, adjust excess tension in the cable (206).
[00040] According to above architecture, one of the primary efficacies of the present invention is the improved driving/riding experience. The improved driving/riding experience is ensured due to elimination of the delay in throttle response which improves the responsiveness of prime mover.
[00041] According to above architecture, one of the primary efficacies of the present invention is the improved reliability of electronically controlled throttle cable actuation system. The reliability is improved due to elimination of slackness in the cable through angular adjustment of throttle position sensor and secondary pulley as a single unit.
[00042] According to above architecture, one of the primary efficacies of the present invention is the improved durability of electronically controlled throttle cable actuation system. The throttle position sensor is attached to handlebar tube and enclosed within cover member which additionally covers wiring harness. Therefore, without use of dedicated cover the throttle position sensor is protected from water and foreign debris like dust. Further, the improved durability reduces the additional operation cost due to frequent replacement of the throttle position sensor.
[00043] According to above architecture, one of the primary efficacies of the present invention is the cost effective electronically controlled throttle cable actuation system configured so as to achieve a compact vehicle layout while still enabling simple adjustment or compensation of cable slack. The cable is enclosed within handlebar cover and cover member. Thereby, cable is protected against environmental influences, such as corrosion due to humid air without need of additional sheath. Therefore, reducing the overall weight of cable.
[00044] The above-described embodiments, and particularly any “preferred” embodiments, are possible examples of implementations and merely set forth for a clear understanding of the principles of the invention. It will be apparent to those skilled in the art that changes in form, connection, and detail may be made therein without departing from the spirit and scope of the invention. Like as per alternative embodiment the arc shaped slots can be provided in flange shaped base portion of throttle position sensor and holes in the brackets.
