Abstract
A motor-driven power steering control apparatus for determining pertinent timings for starting/stopping application of steering assist torque includes a motor for applying an assist torque, a sensor for detecting a steering torque, a driving unit for operating the motor in dependence on a detected steering torque, a command unit for commanding starting and stopping of operation of the motor, and a motor operation decision unit. When stopping of operation of the motor is commanded by the command unit, the motor operation decision unit stops driving operation of the motor while commanding the driving unit to stop application of the steering assist torque when a state in which a steering torque is not greater than a predetermined value for stoppage has continued for a predetermined time period.
