Patent ID: 7568551

Claim:
An electric power steering control apparatus, comprising: a motor for generating an assist torque for supplementing a steering torque exerted by a driver of a vehicle; steering torque detecting means for detecting the steering torque; vehicle speed detecting means for detecting a speed of the vehicle; addition command torque receiving means for receiving an addition command torque input from an external device; steering assist torque calculating means for calculating a steering assist torque for supplementing the steering torque; target assist torque calculating means for adding the steering assist torque and the addition command torque together to calculate a target assist torque of the motor; and motor driving means for driving the motor based on the target assist torque, wherein the steering assist torque calculating means calculates an added value of the steering torque and the addition command torque, and multiplies the added value by a gain corresponding to the speed of the vehicle to calculate the steering assist torque.
