Abstract: In a vehicle control device, a brake feedback control unit calculates a brake feedback torque Tfb-BK using 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 Tfb-BK when the current state is a brake feedback limitation state, and stores as an output value the brake feedback torque Tfb-BK that 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 Tfb-BK as 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.

An engine and a motor for outputting driving power are controlled to drive the vehicle at the target vehicle speed V*.

In response to the driver's subsequent release of the brake pedal, the drive control sets the vehicle speed V at the moment to the target vehicle speed V* (step S510) and restarts constant-speed drive (cruise drive).

Abstract: When a deceleration intention detector detects that an occupant has apprehension about a condition ahead of his own vehicle and attempts to decelerate the own vehicle, a detection area setter enlarges a detection area in which a control object is detected, upon a command from a control object determinator.
