, Description:FIELD OF THE INVENTION
[0001] Present invention relates to hybrid electric vehicles. More particularly, the present invention relates to a Smart Hybrid Accelerator (SHA) for hybrid electric vehicles.

BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] One of the greatest challenges being faced by the human race today is undoubtedly climate change and its potentially catastrophic consequences for humanity. The ever rising greenhouse gas emissions coupled with massive urbanization trends create a further challenge where large scale migration to urban areas is creating several high density population clusters that require tremendous resources for survival such as round the clock availability of utilities, products, and services to support such urban lifestyle. As a consequence, one of the highest contributors to global greenhouse gas emissions is the transportation sector, responsible for nearly a quarter of greenhouse gas emissions every year. The urban vehicular emissions not only affect the global temperature rise and the climate, but also the health of the urban populations as they inhale those harmful vehicular emissions that create health hazards including early deaths and COPD (chronic obstructive pulmonary disorders).
[0004] There has been strong scientific evidence and record of such health hazards and ailments which need to be addressed with a sense of urgency, by providing more workable solutions for sustainable mobility which reduces the quantum of harmful emissions. At the same time, the consumers of the automobile sector are used to certain conveniences with respect to ease of fuelling, long range on a full fuel tank, as well as certain driving features which can’t be taken away from them in an instant by switching to non-IC engine vehicles such as fully electric vehicles, which are short on features and conveniences keeping in mind the mass affordability factor. The fully electric vehicles have several shortcomings such as long recharge times, inconvenience of not having adequate charging facilities, range anxiety for drivers and passengers as a result of relatively short range on a single charge, load carrying limitations in steep uphill terrains, etc.
[0005] Therefore, there is a need to first migrate to an intermittent stage of hybrid electric mobility solution whereby all shortcomings of a fully electric vehicle as mentioned above can be effectively addressed and during urban and large parts of inter city transportation routes, the vehicles can operate on fully electric mode easily. This will create at least 80% more green miles by consumers switching to intelligent plug in hybrid electric vehicles and operating in zero emissions mode for most of the miles driven.
[0006] There is, therefore, a need in the art to develop solutions where transition from existing IC engine powered vehicles to hybrid electric vehicles gets seamless. To aid this, if the vehicle controls that are managed by the user such as speed control, steering control and braking for a hybrid vehicle be kept similar to IC engine powered vehicles then the acceptance by the masses to drive or ride such hybrid electric vehicles will be adequate and would make it much easier for these vehicles to acquire a mainstream position.

The EV sensor can be operatively coupled to the module, where the EV sensor can be configured to transmit the signal generated by rotation of the first cylindrical disc to the electric motor controller through the connector. The ICE sensor can be operatively coupled to the module, where the ICE sensor can be configured to transmit the signal generated by rotation of the second cylindrical disc through the connector to the IC engine throttle body valve in case where the throttle body valve is electronically controlled.
[0058] According to an aspect of the present disclosure, a mechanical mode can be operated when the cable arrangement is used to transmit the rotation of the second cylindrical disc, and provide motion for actuation of the IC engine throttle body valve. An electronic mode can be operated when signals are generated by the ICE sensor due to rotation of the second cylindrical disc, and the ICE sensor along with the ICE connector provides the signal to the IC engine throttle body mechanism.
[0059] FIG. 1 illustrates the general arrangement of the Smart Hybrid Accelerator (SHA), in accordance with an embodiment of the present disclosure.
[0060] According to an embodiment, a Smart Hybrid Accelerator (SHA) 100 is implemented in hybrid electric vehicles (also interchangeably referred to as hybrid electric vehicles either two wheelers, three wheelers or four wheelers or multi-axle vehicles). The Smart Hybrid Accelerator (SHA) 100 comprises a module 102, an input cable unit 104, a module cover 106, an EV sensor 108, an EV connector 110, an ICE sensor 112, an ICE connector 114, a cable arrangement 116.
[0061] According to an embodiment, the Smart Hybrid Accelerator (SHA) 100 is configured to perform the function of accelerator for both Electric and IC engine drives, thus providing an ease of operation to the user of the vehicle allowing them to maintain their driving habits. The Smart Hybrid Accelerator (SHA) 100 can be operated with both a twist type handle grip accelerator commonly used in two or three wheeler vehicles and a foot pedal type accelerator commonly used on four wheeler or multi-axle vehicles. The module 102 is connected to the twist type handle grip accelerator or the foot pedal type accelerator through the input cable unit 104. The EV sensor 108 can provide the signal to the electric motor drive controller through the EV connector 110. The ICE sensor 112 provides the signal to the IC engine throttle body through the connector 114 and alternatively the cable arrangement 116 can provide the necessary actuation for the IC engine throttle body valve in case the IC engine uses a cable type arrangement for its accelerator. Thus, the Smart Hybrid Accelerator (SHA) 100 can be used for both types of IC engine accelerators – the cable type as well as the electronic signal type. The module cover 106 can provide access to the elements inside the module 102 of the Smart Hybrid Accelerator (SHA) 100 at the time of service and repairs.
[0062] FIG. 2 illustrates the Smart Hybrid Accelerator (SHA) with cable type ICE accelerator (ICE side view), in accordance with an embodiment of the present disclosure.
[0063] FIG. 3 illustrates the Smart Hybrid Accelerator (SHA) with cable type ICE accelerator (EV side view), in accordance with an embodiment of the present disclosure.
[0064] According to an embodiment, the Smart Hybrid Accelerator (SHA) 100 includes the input cable unit 104, an EV sensor 108, an EV connector 110, a cable arrangement 116, an EV disc (interchangeably referred to as first cylindrical disc) 118, a cover disc 124, an ICE torsion spring 130, an ICE disc cable type (interchangeably referred to as a second cylindrical disc) 132.
[0065] In an embodiment, FIGs 2 and 3 represent the main components of the Smart Hybrid Accelerator (SHA) 100 which are assembled and contained inside the module 102. There are two sets of cylindrical discs, the first cylindrical disc 118 which includes a potentiometer type magnetic coupling and sensor arrangement that provides the speed control for the electric drive, and the second cylindrical disc 132 that provides the speed control for the IC engine drive. A cover disc 124 completes the assembly of the SHA 100 elements.
[0066] FIG. 4 illustrates the exploded view of the Smart Hybrid Accelerator (SHA) assembly (EV side view), in accordance with an embodiment of the present disclosure.
[0067] FIG. 5 illustrates the exploded view of the Smart Hybrid Accelerator (SHA) assembly (ICE side view), in accordance with an embodiment of the present disclosure.
[0068] According to an embodiment, the Smart Hybrid Accelerator (SHA) 100 includes the module 102, the input cable unit 104, an EV sensor 108, an EV connector 110, a cable arrangement 116, an EV disc (interchangeably referred to as first cylindrical disc) 118, an EV torsion spring 120, the cover disc 124, the ICE torsion spring 130, the ICE disc cable type (interchangeably referred as second cylindrical disc) 132, rivet pins (interchangeably referred as a set of pins) 134, and slot 136.
[0069] In an embodiment, FIGs 4 and 5 represent the exploded views of the Smart Hybrid Accelerator (SHA) 100 and its assembled components. The input cable unit 104 connects the external handle grip or foot pedal of the vehicle to the module 102 and thereby transmits the user’s inputs to the SHA. The first cylindrical disc 118 and the second cylindrical disc 132 are connected with the set of pins 134. The set of pins 134 is riveted to the flat surface of the first cylindrical disc 118, passes through the angular slots 136 provided on the flat surface of the second cylindrical disc 132, and are riveted at the other end to the surface of the cover disc 124. The second cylindrical disc 132 is thus sandwiched between the first cylindrical disc 118 and the cover disc 124 and is held together as a single assembly with the set of pins 134. Each of these cylindrical discs also has a groove on its cylindrical surface through which runs a cable. The input cable unit 104 is wound on the first cylindrical disc 118 and has its end locked into the end of the groove on this disc. Another cable arrangement 116 is wound on the second cylindrical disc 132 and has one of its ends locked into the end of the groove on this disc. The other end of cable arrangement 116 is connected to the throttle body valve mechanism of the IC engine. When the vehicle user operates the handle grip or foot pedal accelerator, the inputs are transmitted to the SHA 100 by the movement of the input cable unit 104. This movement of the input cable unit 104 causes the first cylindrical disc 118 to rotate and provides the necessary signal to the Electric motor drive controller through the EV sensor 108. The rotation of the first cylindrical disc 118 causes the set of pins 134 to rotate and when the set of pins 134 reaches the end of the angular slots 136 the second cylindrical disc 132 starts to rotate. The rotation of the second cylindrical disc 132 enables the cable arrangement 116 wound on it to transmit this motion for actuation of the IC engine throttle body valve. The lag in the start of the rotation of the second cylindrical disc 132 due to the travel of the set of pins 134 through the angular slots 136 provides the designed and desired phase lag for the accelerator control of the IC engine drive compared to the accelerator control of the electric motor drive. The angular slots 136 on the second cylindrical disc (132 and 122) are designed to provide a phase lag with of a configurable predefined threshold value (for example 10 degrees) while using the combined mode, where actuation of the speed control for the IC engine drive lags the actuation of the speed control of the electric motor drive by the predefined threshold value of 10 degrees. The torsion springs 120 and 130 ensures that both the cylindrical discs 118 and 132 return to their original state of rest when the vehicle user’s input through the input cable unit 104 is suspended.
[0070] FIG. 6 illustrates the Smart Hybrid Accelerator (SHA) with electronic type ICE accelerator (ICE side view), in accordance with an embodiment of the present disclosure.
[0071] FIG. 7 illustrates the Smart Hybrid Accelerator (SHA) with electronic type ICE accelerator (EV side view), in accordance with an embodiment of the present disclosure.
[0072] According to an embodiment, the Smart Hybrid Accelerator (SHA) 100 includes the module 102, the input cable unit 104, an EV sensor 108, an EV connector 110, an ICE sensor 112, an ICE connector 114, an EV disc (interchangeably referred as a first cylindrical disc) 118, an ICE disc (electronic) 122, and the cover disc 124.
[0073] In an embodiment, FIGs 6 and 7 represent the main components that are assembled and contained inside the module 102 for the alternative design of the SHA 100, when the IC engine accelerator control uses an electronic type arrangement 122 in place of a cable type accelerator control.
[0074] FIG. 8 illustrates exploded view of the Smart Hybrid Accelerator (SHA) assembly for electronic type ICE accelerator (EV side view), in accordance with an embodiment of the present disclosure.
[0075] FIG. 9 illustrates exploded view of the Smart Hybrid Accelerator (SHA) assembly for electronic type ICE accelerator (ICE side view), in accordance with an embodiment of the present disclosure.
[0076] According to an embodiment, the Smart Hybrid Accelerator (SHA) 100 includes the module 102, the input cable unit 104, an EV sensor 108, an EV connector 110, an ICE sensor 112, an ICE connector 114, an EV disc (interchangeably referred to as first cylindrical disc) 118, an EV torsion spring 120, an ICE disc (electronic) 122, the cover disc 124, the ICE torsion spring 130, rivet pins (interchangeably referred as a set of pins) 134, and slot 136.
[0077] In an embodiment, FIGs 8 and 9 represent the exploded views of an alternative design of the SHA 100 and its assembled components. FIGs 4 and 5 operate based on the second cylindrical disc 132 that provides the accelerator control to the IC engine drive. In the alternative design, the second cylindrical disc 122 has a potentiometer-type magnetic coupling and sensor arrangement instead of cable arrangement 116. The rotary motion is imparted to the second cylindrical disc 122 by the first cylindrical disc 118 in the same way by the riveted pins 134 and angular slots 136. The rotation of the second cylindrical disc provides the necessary signal to the IC engine throttle body mechanism through the ICE sensor 112.
[0078] In another embodiment, the present invention the Smart Hybrid Accelerator (SHA) 100 provides the accelerator control for both the electric and IC engine drives of the hybrid electric vehicle and for all modes of operation – electric mode, IC engine mode and combined mode through a single modular unit.
[0079] Although this present invention has been described herein with respect to a number of specific illustrative embodiments, the foregoing description is intended to illustrate, rather than to limit the invention. Those skilled in the art will realize that many modifications of the illustrative embodiment could be made which would be operable. All such modifications, which are within the scope of the claims, are intended to be within the scope and of the present invention.
