ELECTRIC VEHICLE CONTROL DEVICE

摘要

An angular acceleration monitor (37) may monitor whether or not an angular acceleration of a wheel (2) detected by an angular acceleration detector (39) is equal to or smaller than an acceptable angular acceleration (W) that is calculated with the following formula (1):
where k1 is a constant;
where Tt is a total drive torque that is a sum of drive torques of all motor units (6) that drive wheels (2) of the vehicle, m is vehicle mass, r is tire radius, and R is reduction ratio of a reducer unit (7) interposed between the motor unit (6) and the wheel (2). A slip-responsive controller (38) causes, if it is determined that the acceptable angular acceleration (W) is exceeded, a motor controller (33) to reduce a drive torque of the motor unit(s).
