Title:
ELECTRIC BRAKE DEVICE, BRAKE CONTROL DEVICE, AND CONTROL PARAMETER CALIBRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/262278
Kind Code:
A1
Abstract:
In the present invention, a main ECU controls a brake force by driving an electric motor of a brake mechanism on the basis of a detection value of a thrust sensor that is provided to the brake mechanism. The main ECU calibrates (corrects) the detection value of the thrust sensor on the basis of a drive force when the drive force exceeds the brake force, the drive force being imparted to left and right front wheels constituting drive wheels in a state where the brake force is being imparted to a right rear wheel or a left rear wheel by the brake mechanism.
