Abstract
In a vehicle control device, a brake feedback control unit calculates a brake feedback torque Tusing a PID control model when a current state is a brake feedback use state. The brake feedback control unit stops the calculation of the brake feedback torque Twhen the current state is a brake feedback limitation state, and stores as an output value the brake feedback torque Tthat is output at a brake limitation start timing. At a brake limitation release timing, the brake feedback control unit restarts the feedback control using the stored brake feedback torque Tas an initial value. The brake mechanism can thereby generate a predetermined brake torque of not more than 0 [N·m] immediately after the brake limitation release timing.
