The present invention provides a downsized vehicle control apparatus which is capable of controlling two DC separately excited motors. An armature of a first motor, an armature of a second motor and an armature chopper element for controlling the drive of the motors which is common to both of those motors are connected in series between the ends of a battery, and a drive circuit turns on/off the common armature chopper element for controlling the drive of the motors and a plurality of field chopper elements for the respective first and second motors to control the armature currents and the field currents in the first and second motors, respectively, thereby driving both of the motors with the desired rotational frequency or torque. The drive circuit controls the on/off operation of an armature chopper element for controlling regenerative braking which is connected in parallel to the series circuit consisting of the armature of the first motor and the armature of the second motor at the time of the regenerative braking to control a current flowing in the armatures of the first and second motors.
