Abstract
A braking control device applicable to a vehicle having an electric parking brake with a motor-driven wheel braking mechanism includes a control unit, an offset estimation unit, and an offset correction unit. Based on a target motor current value indicating a target value of 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 controls the current to the motor such that the detection value equals the target motor current value. The offset estimation unit determines an offset estimation value indicating an estimated value of offset of the detection value from the current sensor, based on 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 based on the offset estimation value.

6. A braking control device to be applied to a vehicle provided with an electric parking brake having a wheel brake mechanism to be driven by a motor, the braking control device comprising:
-
a control unit configured to execute motor current control of controlling, on the basis of a target motor current value, which is a target value of current to be input to the motor, and a detection value from a current sensor configured to detect the current to be input to the motor, the current to be input to the motor so that the detection value from the current sensor is equal to the target motor current value; an offset estimation unit configured to determine an offset estimation value, which is an estimated value of an 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 vehicle'"'"'s stoppage; and an offset correction unit configured to correct the target motor current value or the detection value from the current sensor on the basis of the offset estimation value. - View Dependent Claims (7, 8, 9, 10, 11, 12)
