VEHICLE CONTROL DEVICE

A vehicle control device includes a controller switching between normal and constant-speed control modes. The normal mode involves controlling a vehicle driving force in accordance with an acceleration-deceleration operation. The constant-speed control mode involves controlling the driving force regardless of the acceleration-deceleration operation to maintain a vehicle speed at a target vehicle speed. In the constant-speed control mode, the controller executes constant-speed control involving calculating the target driving force using integral control and controlling the driving force to the target driving force, interrupts the constant-speed control if a requested driving force corresponding to an accelerator-pedal opening degree exceeds the target driving force, executes override involving controlling the driving force to the requested driving force, and sets an integral-control component based on the requested driving force during the override if a wheel fails to pass over a step when the override is terminated and the constant-speed control is to be resumed.
