ABSTRACT:
A riskiness reference value Riskm is corrected and calculated for each target object according the a road surface friction coefficient based on a vehicle-to-target time and a collision allowance time, and a riskiness Riskm (ΔAm) for each three-dimensional object is set based on the riskiness reference value Riskm with a range which uses a probability distribution given in an azimuthal angle direction where each target object exists, whereby a riskiness Risk (ΔA) is set for each azimuthal angle. Then, alarming and brake controlling are made to be executed according to a riskiness Risk (0) at an azimuthal angle of 0, and a steering angle control amount θstrt is obtained from the current riskiness Risk (ΔA) of each azimuthal angle and an estimated riskiness Risk (ΔA)e of each azimuthal angle after a set time period.
