Brake control device and brake control method

Abstract

A brake control device includes: an acquisition section that acquires a steering angle and a first steering angular velocity passed through a first low-pass filter; a braking processing section that decides to apply braking force to a wheel by a brake device when the absolute value of steering angle is not less than a predetermined angle and the absolute value of first steering angular velocity is not less than a predetermined velocity; and a control section that drives the brake device according to the braking processing section's decision. The acquisition section acquires a second steering angular velocity including higher frequency components than the first steering angular velocity, the braking processing section decides to execute predetermined preload control when the absolute value of second steering angular velocity is not less than the predetermined velocity, and the control section executes preload control on the brake device to improve the brake device's responsiveness.
