<P>PROBLEM TO BE SOLVED: To provide a vehicle electric drive system which is responsive to or coordinated with the operation of the drive brakes. <P>SOLUTION: This invention relates to a vehicle electric drive system. There is a need for a brake responsive vehicle electric drive system. A vehicle electric drive system includes: an internal combustion engine 12; an electric motor/generator 14 driven by the engine; and drive wheels 26 and 30 driven by a traction motor/generator 24 and 28. The motor/generator 14 is controlled by a control system which receives signals from an operator speed control member 36, a wheel speed sensors, and a pair of brake pedal position sensors 58 and 60, each connected to a corresponding left or right brake pedal 57 and 59. In response to operation of the brake pedals, the controller coordinates operation of the electric drive system with operation of the brake pedals. <P>COPYRIGHT: (C)2008,JPO&INPIT |
