  • Patent number: 5376868
    Abstract: A driving force controller for an electric motor vehicle which suppresses changes in behavior of a vehicle when a right or left driving wheel experiences trouble and detects vehicle conditions to independently control the driving force of each wheel so as not to deviate from a predetermined range. The driving force controller computes a driving force for each wheel in accordance to a demand value for driving force and a detected vehicle traveling condition to drive each wheel independently by electric motors. Motor drivers control the motors so that each motor generates power corresponding to the value of driving force computed therefor. A driving demand detector detects the value of driving force demanded for the vehicle and a vehicle condition detector detects a traveling condition of the vehicle. Wheel driving condition detectors detect conditions at the wheels.
