PROBLEM TO BE SOLVED: To presume a state of a friction coefficient between a road surface and a tire before starting automatic brake control. SOLUTION: Slip of a driving wheel in accelerator operation is detected, acceleration of the driving wheel at the time of detecting the slip is detected, the state of the friction coefficient between the road surface and the tire is presumed in accordance with the detected acceleration, and braking force or braking deceleration is adjusted in accordance with a presumption result. The presumption result is divided into a plurality of stages in correspondence with a degree of the friction coefficient and output, and the braking force or the braking deceleration is divided into a plurality of stages in correspondence with the presumption result divided into a plurality of the stages and reduced.
