Title:
ELECTRIC BRAKE DEVICE AND ELECTRIC BRAKE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/159813
Kind Code:
A1
Abstract:
The present invention provides an electric brake device and an electric brake system in which power consumption can be reduced without increasing the size of an electric motor. In the present invention, an electric brake control device (2) is provided with a vehicle stop determination means (23d), a brake load commander (22), a brake load controller (24), and a brake power reducer (23). The brake load commander (22) outputs a target brake load Fr on the basis of a required brake force. The brake load controller (24) outputs a command value Ar of brake load retaining power applied to an electric motor (4) according to the target brake load Fr. The brake power reducer (23) reduces the command value Ar of the brake load retaining power, applied to the electric motor (4) on the basis of the required brake force Brk, compared to that in a vehicle stopped state.
