  • Publication number: 20220073045
    Abstract: The objective is to suppress a delay in the response of pressing force of an electric brake, when braking and non-braking are alternately repeated in an electric-brake control apparatus. An electric-brake control amount calculation unit of an electric-brake control apparatus according to the present disclosure calculates a control amount for securing a clearance between a brake pad and a brake disk, based on a position of the brake pad, calculated by a position calculator at a non-braking time, and secures the clearance by changing the control amount in two or more separate steps at a time when the braking is switched to the non-braking. As a result, it is made possible to obtain an electric-brake control apparatus that can suppress a delay in the response of pressing force of an electric brake, when braking and non-braking are alternately repeated.
