PROBLEM TO BE SOLVED: To accurately and adequately control a brake force according to brake requirement from a driver. SOLUTION: A target deceleration Gst is calculated based on a pushing stroke Sp of a brake pedal (S20), a target deceleration Gpt is calculated based on a master cylinder pressure Pm (S30), a weightαfor the target deceleration Gpt is calculated based on a final target deceleration Gt calculated at previous time (S40), a final target deceleration Gt is calculated as a weighting sum of the target deceleration Gpt and the target deceleration Gst (S50), a target wheel cylinder pressure Pti for each wheel is calculated as a value proportional to the final target deceleration Gt (S60), a wheel cylinder pressure Pti for each wheel is feedback controlled so as to be the target wheel cylinder pressure Pti (S70).
