Control system for electric vehicle
 When the voltage of a battery is dropped down to a first threshold value (9.5 V) or less, the driving force of a motor is decreased to a level Y(0)-Y(7) of a limit power determined in accordance with a remaining capacity of the battery. When the voltage is not restored even after a predetermined time is lapsed from the decreasing of the driving force to the level Y(0)-Y(7), the driving force is further decreased down to a lower level Y(0)-Y(7). When the voltage of the battery is restored to a second threshold value (10 V), the driving force of the motor is gradually increased up to a level Z(0)-Z(7) of a limit power determined in accordance with the capacity of the battery. Thus, it is possible to prevent a deep discharging of the battery, while minimizing the influence on the traveling of the vehicle.
