Complementary regenerative torque system and method of controlling same
First Claim
1. A vehicle having a regenerative torque system comprising:
- a drive train including;
an engine having an accelerator pedal position sensor for sensing accelerator pedal position, said accelerator pedal position sensor generating an accelerator pedal position signal representative of said accelerator pedal position;
a transmission unit driven by said engine for driving at least a pair of wheels for propelling said vehicle;
a regenerative torque unit for storing and supplying energy to said drive train to selectively supply on demand complementary torque thereto, said regenerative torque unit disposed upstream said transmission relative to said engine, an engine control module for controlling said engine in response to operating conditions;
a regenerative torque control module disposed between said accelerator pedal position sensor and said engine control module, said regenerative torque control module intercepting said accelerator pedal position signal and modifying said signal in response to a mode of operation of said regenerative torque unit.

Abstract
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.
