A method and device for a vehicle having wheels which are each assigned a sensor for generating wheel signals. The unit determines whether a wheel is affected by a failure of the corresponding wheel signal. The unit acquires wheel signals which are assigned to the wheels, and for a wheel affected by a wheel signal failure, the corresponding wheel signal is acquired in the form of a substitute signal. The unit calculates a target brake pressure for a wheel at which an increase in brake pressure is necessary. The increase in brake pressure takes place in accordance with the wheel signal which is obtained for the wheel and in accordance with the determination as to whether the wheel is affected by a wheel signal failure. The unit further determines a slip threshold for an anti-lock brake control operation applied to the wheel affected by the wheel signal failure.

A braking control device includes a target vehicle speed setting unit, a braking power control unit, and a low friction coefficient region recognition unit. The low friction coefficient region recognition unit recognizes a low friction coefficient region of a road surface between a current position of an own vehicle and a target position. The braking power control unit estimates a maximum deceleration rate assuming braking to be started after passage through the low friction coefficient region to cause deceleration to a target vehicle speed at the target position. On the condition that the maximum deceleration rate is smaller than a predetermined upper limit on a deceleration rate, the braking power control unit causes a start of generation of braking power after the passage through the low friction coefficient region.
