Embodiment Construction
[0016] 2-3 illustrate components according to a preferred embodiment of the present invention. The internal combustion engine 1 acts as the main torque source for driving the drive train including the gearbox 3, the associated drive shaft, the differential between the drive wheels and, in the case of a four-wheel drive vehicle, splitting the torque between the front and rear axles Supplied transfer case 5. A regenerative torque source (12) is used to provide required assist torque to the drive train and to store energy during deceleration / vehicle braking. In a preferred embodiment, a torque accumulating device (eg, integrated pump / motor) (10) is positioned between the engine and the gearbox.
[0017] The invention is particularly suitable for the on-demand transfer of complementary torque to a drive train. The amount of torque delivered to the transmission is the sum of the torque provided by the engine and the torque provided by the regenerative torque source. The regenera...

A complementary regenerative torque system exists for a vehicle including an engine having an accelerator pedal position sensor; a transmission unit; and a drive shaft for driving a pair of wheels for propelling the vehicle. The regenerative torque system selectively stores and supplies energy to the drive train to provide on demand complementary torque thereto. The regenerative torque system may be either hydraulic or electric in nature and may be disposed upstream or downstream of the transmission relative to the engine. A regenerative torque control module is disposed between the accelerator pedal position sensor and the engine control module and intercepts the accelerator pedal position signal and modifies it in response to the mode of operation of the regenerative torque system and forwards the modified throttle signal to the engine control module. Likewise, the regenerative torque control module intercepts signals from the engine control module and modifies the same prior to broadcasting them to the rest of the vehicle's control modules.
Description
technical field [0001] The present invention relates to a controller for a complementary Regenerative Torque System (RTS, Regenerative Torque System) for a vehicle, an interface to existing vehicle components and its associated control. Background technique [0002] Conventional vehicles have an internal combustion engine as the single source of torque. FIG. 1 shows a flow chart of signal and torque flow and related controls for a conventional four-wheel drive vehicle. An accelerator pedal position (APP) sensor is often employed to indicate desired engine torque, while an engine control module (ECM) controls the engine in response to APP and other sensed conditions. The ECM communicates with the Transmission Control Module (TCM), which controls the transmission based on APP, engine output torque, engine speed, and vehicle speed, among other conditions. Such assemblies are well known in the art. These prior art systems do not have the ability to provide complementary or co...
