Abstract:
1. A motor control apparatus that drives and 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 of said drive shaft and a rotating shaft of said motor; a first skid detection module that detects a skid due to wheel spin of the drive wheels, based on the measured angular acceleration; a first torque restriction control module that, in response to detection of a skid by said first skid detection module, restricts torque output and controls said motor with the restricted torque output, so as to reduce the skid; a first integration module that integrates the angular acceleration, which is measured by said angular acceleration measurement module, to give a time integration thereof since detection of the skid by said first skid detection module; and a first torque restoration control module that, in response to at least a reducing tendency of the skid, restores the torque output, which is restricted by said first torque restriction control module, according to the time integration of the angular acceleration given by said first integration module and controls said motor with the restored torque output.
