Claim 9:
10. An electric vehicle control system, comprising:
a front drive motor configured to drive a front wheel;
a rear drive motor configured to drive a rear wheel; and
a control unit configured to drive and control the front drive motor and the rear drive motor, wherein
the control unit causes an electric vehicle to brake by applying a front braking torque to the front drive motor and applying a rear braking torque to the rear drive motor, and
the control unit executes:
during braking of the electric vehicle,
a distribution torque changing process that increases the front braking torque proportional to a decrease in the rear braking torque when a slip of the rear wheel is detected, wherein a sum of the front braking torque and the rear braking torque is substantially maintained during the distribution torque changing process, and
a torque limiting process that reduces the front braking torque and the rear braking torque when the slip of the rear wheel is eliminated by the distribution torque changing process and a slip of the front wheel is detected.
