Title:
BRAKING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026893
Kind Code:
A1
Abstract:
This braking control device is applied to a vehicle provided with an electric parking brake having a wheel braking mechanism driven by a motor, and is provided with a control unit, an offset estimation unit, and an offset correction unit. On the basis of a target motor current value that is a target value of a current to be inputted to the motor and a detection value from a current sensor that detects the current to be inputted to the motor, the control unit executes motor current control of controlling the current to be inputted to the motor such that the detection value from the current sensor is equal to the target motor current value. The offset estimation unit determines an offset estimation value that is an estimated value of offset of the detection value from the current sensor, on the basis of a behavior of the vehicle after lock control at the time of the vehicle's stoppage. The offset correction unit corrects the target motor current value or the detection value from the current sensor on the basis of the offset estimation value.
