Title:
A steering controller and a steering auxiliary torque control method for the same
Document Type and Number:
Japanese Patent JP6058214
Kind Code:
B2
Abstract:
Provided is a steering control device capable of causing a steering torque to follow a target steering torque when a driver holds a steering wheel (1) for steering, thereby achieving smooth steering, and making an adjustment so that the steering wheel (1) returns to a neutral position at an appropriate speed, when the driver releases his or her hands from the steering wheel (1), thereby being able to achieve satisfactory steering feelings even in a steering state and in a hands-off state. A motor (6) is controlled based on a motor steering assist torque, which is a sum of a first steering assist torque, which is proportional to an integral value of a deviation between the target steering torque and the steering torque, and a second steering assist torque, which is proportional to a motor rotational angular velocity and acting in a direction of suppressing a return speed of the steering wheel (1) when the steering wheel (1) returns to the neutral position.
