Abstract
A method of controlling a powertrain for a hybrid vehicle, the method including providing an internal combustion engine, providing a motor generator operatively coupled to the internal combustion engine, providing an automatic transmission operatively coupled to the internal combustion engine, and actuating the motor generator to a certain speed to restart the vehicle.
Claims21
A method of controlling a powertrain for a hybrid vehicle, the method comprising:
- providing an internal combustion engine;
- providing a motor generator operatively coupled to said internal combustion engine;
- providing an automatic transmission operatively coupled to said internal combustion engine;
- and
- actuating said motor generator to a certain speed to prime said automatic transmission.
A hybrid vehicle powertrain system comprising:
- an internal combustion engine having a crankshaft;
- an automatic transmission having a torque converter coupled to said crankshaft;
- a motor generator coupled to said crankshaft;
- a throttle position sensor for detecting the position of a throttle plate operatively coupled to said internal combustion engine;
- a pedal position sensor for detecting the position of an accelerator pedal located within the hybrid vehicle;
- a manifold pressure sensor located in said internal combustion engine;
- and
- at least one controller for controlling said internal combustion engine and said motor-generator, said controller including software to control said motor-generator to actuate said torque converter.
A method of starting a hybrid vehicle equipped with an automatic transmission, the method comprising:
- providing an internal combustion engine in the hybrid vehicle;
- providing a motor generator coupled to said internal combustion engine;
- providing an automatic transmission having a torque converter coupled to said internal combustion engine;
- actuating said internal combustion engine by actuating said motor generator, whereby said torque converter is actuated and primed;
- and
- starting said internal combustion engine.
