Title:
ELECTRIC BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/060005
Kind Code:
A1
Abstract:
The present invention improves operability and ability to conform to the target braking force and improves braking feel when applying a small braking force. A clearance-estimating means (13) for estimating the clearance, including negative clearances, between friction materials (45A, 45B) and the brake using a motor rotation angle (θ) is provided in a brake control unit (2). The target braking force (Fr) is compared with the switch-determining braking force (Frsw) and when the friction materials are near the brake, a situation in which the target braking force (Fr) is small, the brake control unit performs clearance control, that is, control using the target clearance (Cr). At or above the switch-determining braking force (Frsw), the brake control unit controls braking force.
