Title:
電動駐車制動装置
Document Type and Number:
Japanese Patent JP6418097
Kind Code:
B2
Abstract:
An electric parking brake device generates pressing force by pressing friction materials against a brake disc by causing a piston to move by motor operation. A control device executes: parking processing wherein the motor increases the pressing force to an initial pressing force higher than a lower-limit pressing force; and re-drive processing wherein the motor is driven and the pressing force increased at a re-drive time, which is a predetermined time after the end of execution of parking processing. During parking processing, the control device uses one among the initial pressing force and the predetermined time, in addition to a pressing force decrease characteristic corresponding to an assumed temperature set for use in calculation, as a basis to calculate the other of the initial pressing force and the predetermined time such that the pressing force becomes equal to or less than the lower-limit pressing force at the re-drive time.
