Title:
STEERING CONTROLLER AND STEERING SPEED DETECTION METHOD
Document Type and Number:
Japanese Patent JP2014227143
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain a steering speed free from an offset error.SOLUTION: A steering controller comprises: a steering speed calculation unit 12 obtaining a first steering speed based on a current detection value of a current sensor 9 and a voltage detection value of a voltage sensor 10, calculates a correction value of the first steering speed based on a detection value of a steering angle, and correcting the first steering speed using the correction value to output the corrected first steering speed as a steering speed; a first steering auxiliary torque calculation unit 15 obtaining a first steering auxiliary torque for returning a steering system to a neutral position based on the steering speed; a second steering auxiliary torque calculation unit 17 obtaining a second steering auxiliary torque for assisting in driver's steering based on a driver's steering torque detected by a torque sensor 5; and a current driver 19 for driving a motor based on the first and second steering auxiliary torques.
