A vehicle controller includes an F/C control section, a battery voltage detection section, an AT control section, an alternator, and an ECU. The ECU determines the difference between a target deceleration for varying deceleration smoothly and a deceleration attained at each gear stage as a target deceleration which is generated by the alternator. The ECU compensates for the difference between target deceleration and the deceleration by the target deceleration to smooth variations in the deceleration of the whole vehicle, thereby improving drivability.
