First Claim
Patent Images
1. A hybrid vehicle comprising:
- vehicle wheels, first and second motor-generators, a combustion engine and an energy storage device;
a first coupler between said first motor generator and said engine and a second coupler between said first motor-generator and one of said vehicle wheels, and a coupling between said second motor-generator and said one or another one of said vehicle wheels;
a driver-operated pedal and a comparator for sensing a position of said pedal;
a master controller responsive to said position of said pedal and comprising a command signal output;
a current controller coupled between said energy storage device and one of said electric motor-generators, said current controller comprising a current control signal input;
a signal path between said command signal output and said current control signal input.

Abstract
In a high speed mode of operating and electric-gas hybrid car, the combustion engine is directly engaged to the wheels without a transmission and that vehicle speed is controlled without a throttle by electric generator loading of the engine.
