Abstract
A starting clutch control device controls such that the transmission torque capacity of a starting clutch (clutch torque) becomes a value required to transmit a torque equal to an engine absorption torque at the time of power-off running. A control of gradually increasing a clutch torque is carried out with a delay after an accelerator pedal is depressed during power-off running, to thereby prevent the occurrence of surging vibrations when an accelerator pedal is abruptly depressed during power-off running.
Claims5
A vehicle starting clutch control device for arbitrarily controlling a transmission torque capacity of a starting clutch through an actuator, said vehicle starting clutch control device comprising:
- first control means for controlling said actuator so that said starting clutch is put in a state that said starting clutch completely transmits the output torque of an engine at the time of power-on running with an accelerator pedal being depressed;
- second control means for controlling said actuator so that the transmission torque capacity of said starting clutch becomes a value required to transmit a torque equal to an engine absorption torque corresponding to the engine speed at the time of power-off running without said accelerator pedal being depressed;
- third control means for controlling said actuator so that the transmission torque capacity of said starting clutch is gradually increased to shift said starting clutch to the completely transmitted state when said accelerator pedal is depressed during power-off running;
- and
- delay means for delaying the start of control based on said third control means until a predetermined time after said accelerator pedal is depressed.
