Title:
ELECTRIC BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/262280
Kind Code:
A1
Abstract:
This electric brake device includes one caliper having at least two electric mechanisms for imparting a braking force to a vehicle and maintaining the braking force. The at least two electric mechanisms are driven by means of one drive circuit output, that is, by means of one output from one drive circuit. As a result, the number of drive circuits for driving the electric mechanisms can be reduced, thereby enabling cost to be suppressed, even if it is necessary for many electric mechanisms to be controlled, as is the case when the present invention is applied to a twin bore caliper, for example.
