Zusammenfassung:	PROBLEM TO BE SOLVED: To solve a problem that brake feeling is deteriorated due to sudden slowdown of a vehicle when an assist control is started even if a brake is slowly operated and that steering feeling is deteriorated due to sudden slowdown in avoidance steering operation. SOLUTION: Master pressure P before start of control is always renewed and stored as a pressurizing amount reference value P2 (S124). When a collision prediction level α exceeds a threshold α2 (S116), the pressurizing amount reference value Ps stored at the time is set as a reference value and brake assist force according increase difference of master pressure P from the pressurizing amount reference value Ps is generated (S118, S120).
