A slip angle calculating unit calculates a slip angle of a vehicle body corresponding to a steering wheel angle and a vehicle speed, based on a vehicle wheel angle and the vehicle speed, by an observer of a preset vehicle motion model under a motion equation of a vehicle. A front wheel slip angle calculating unit calculates a front wheel slip angle based on the steering wheel angle, a vehicle speed, a yaw rate, and the calculated vehicle body slip angle. A self-aligning torque calculating unit calculates the self-aligning torque based on the hydraulic chamber pressure of the left side and the hydraulic chamber pressure of the right side in a power cylinder. The vehicle speed, an estimated front wheel slip angle, and the self-aligning torque are inputted to a road friction coefficient setting unit, and the road friction coefficient setting unit sets a road friction coefficient by referring to a map based on the input to output the set value. A road friction coefficient is estimated in wide ranges while reducing noises of sensors.
