Claim Text:
1. A braking control device for a vehicle, comprising: a first deceleration calculation unit that calculates a first estimated vehicle body deceleration by using a detection signal of a wheel speed sensor arranged on the vehicle; a second deceleration calculation unit that calculates a second estimated vehicle body deceleration by using a detection signal of a vehicle body acceleration sensor arranged on the vehicle, the vehicle body acceleration sensor being more distant from a wheel of the vehicle than the wheel speed sensor; an assist control unit that initiates an assist control, which assists increasing of a braking force that is applied to the wheel based on operation of a brake pedal of the vehicle so that the braking force is greater than a braking force applied to the wheel just by the driver's operation on the brake pedal, when the first estimated vehicle body deceleration exceeds a first deceleration determination value and the second estimated vehicle body deceleration exceeds a second deceleration determination value during operation of the brake pedal of the vehicle; an outer disturbance determination unit that determines whether a vibration component based on outer disturbance is included in the first estimated vehicle body deceleration; and a reference value correction unit that corrects the first deceleration determination value to a greater value when the first estimated vehicle body deceleration includes a vibration component based on outer disturbance than when such is not the case, wherein when the second estimated vehicle body deceleration is greater than the sum of the first estimated vehicle body deceleration and a deceleration specified value or when the first estimated vehicle body deceleration has a negative value, the outer disturbance determination unit determines that the first estimated vehicle body deceleration includes a vibration component based on outer disturbance.
