ELECTRIC MOTOR VEHICLE CONTROL APPARATUS AND METHOD FOR REDUCING THE OCCURRENCE OF WHEEL SLIP

摘要

An electric motor vehicle control apparatus has a control circuit which includes a slip/slide detection circuit. A minimum value among the wheel speeds is used to determine a slip condition whereas a maximum value is used to determine a slide condition. A control signal controlling each of the motors driving the wheels may thus be adjusted for the detected slip or slide condition. The control signal may also be generated based on different diameter wheels resulting from frictional induced diameter variations.
