摘要： An electric power steering apparatus that achieves a manual steering even if a steering intervention is performed by a driver during an automatic steering, ensures more safety when a driver steers urgently, and enables both an assist control and a steering angle control. The apparatus includes a steering angle control section that calculates a steering angle control current command value for the steering angle control, and calculates the current command value using at least the steering angle control current command value; this control section has a position control section to calculate a basic steering angular velocity command value, a steering intervention compensating section to obtain a compensatory steering angular velocity command value, and a steering angular velocity control section to calculate a steering angle control current command value with the basic steering angular velocity command value, the compensatory steering angular velocity command value and an actual steering angular velocity. The steering intervention compensating section comprises a compensating map section having a steering intervention compensating map that determines a characteristic of the compensatory steering angular velocity command value to a steering torque, and obtains the compensatory steering angular velocity command value by the steering torque.

摘要： Provided is a steering control apparatus capable of executing driving assistance control even during rotation angle sensor-less control. When an induced voltage generated in a motor is equal to or lower than a threshold voltage at an early stage of execution of the rotation angle sensor-less control and when the driving assistance control is executed based on a command value from a higher-level control apparatus, a second pre-addition angle that is based on the command value is used as a second addition angle in place of a first pre-addition angle that is based on a steering torque. Therefore, even in a situation in which the steering torque is not detected due to, for example, execution of driving assistance, an estimated electrical angle of the motor is calculated by integrating the second addition angle. Then, driving of the motor is controlled based on the calculated estimated electrical angle.
