Abstract
A dual-motor electric vehicle having a control section that determines whether three conditions are satisfied, (1) that a straight-ahead travel instruction has been supplied to the vehicle, (2) that an actual number of motor rotations of an electric motor is less than a target number of motor rotations, and (3) that a motor control signal for bringing the actual number of motor rotations closer to the target number has reached a predetermined upper limit output value. When all conditions are satisfied for at least one of the electric motors of the dual-motor vehicle, the control section performs a downward motor-rotation correction process for at least one of motors by incrementally reducing one of the target number of motor rotations and the upper limit output value of the motor control signal until the respective actual numbers of rotations of the left and right motors substantially coincide with each other.
