Patent ID: 7132806

Claim:
A motor control apparatus that controls a motor, which is mounted on a vehicle and outputs power to a drive shaft linked to drive wheels, said motor control apparatus comprising: an angular acceleration measurement module that measures an angular acceleration of either the drive shaft or a rotating shaft of said motor; a skid detection module that detects occurrence of a skid due to wheelspin of the drive wheels, in response to an increase in measured angular acceleration over a preset value; a first torque restriction control module that, in response to detection of the occurrence of a skid by said skid detection module, sets a certain torque restriction rate to restrict an output torque level for reduction of the skid and controls said motor with the restricted output torque level; and a torque restoration control module that restores the output torque level restricted by said first torque restriction control module and controls said motor with the restored output torque level at a predetermined timing when the angular acceleration measured by said angular acceleration measurement module has an increase in the course of convergence of the skid.
