VEHICLE CONTROL DEVICE

PROBLEM TO BE SOLVED: To reduce the response delay of actual acceleration to target acceleration in a vehicle control device. SOLUTION: A brake feedback control unit calculates brake feedback torque Tfb-BKusing a PID control model when a current state is a brake feedback use state (S330, S340). The...

Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the response delay of actual acceleration to target acceleration in a vehicle control device. SOLUTION: A brake feedback control unit calculates brake feedback torque Tfb-BKusing a PID control model when a current state is a brake feedback use state (S330, S340). The brake feedback control unit stops calculation of brake feedback torque Tfb-PTusing the PID control model when the current state is a brake feedback limitation state, and stores as an output value the brake feedback torque Tfb-BKthat is output at a brake limitation start timing (S360). At a brake limitation release timing, the brake feedback control unit restarts the feedback control using the stored brake feedback torque Tfb-BKas an initial value. The brake mechanism can thereby generate predetermined brake torque which is more than 0 [Nm] in a brake mechanism immediately after the brake limitation release timing. COPYRIGHT: (C)2010,JPO&INPIT
