Abstract
A driving assist apparatus for a vehicle is provided. The apparatus includes a determination unit that determines a state of a traffic flow in a lane in which a ego-vehicle is driving, on the basis of acceleration of the ego-vehicle and inter-vehicle distances to other vehicles around the ego-vehicle. The apparatus also includes a drive control unit that controls a motion of the ego-vehicle and is capable of switching drive control according to a determination result by the determination unit. The drive control unit switches the drive control when the determination result indicates that the state of the traffic flow is a state of a critical region which is present in a transition period from a free-flow state to a mixed-flow state. Here, the free-flow state is a state in which the probability of occurrence of traffic congestion is low, and the mixed-flow state is a state in which a braking state and an acceleration state of a vehicle are mixed.
