Abstract:
1. A driving assist apparatus for a vehicle, comprising: a sensor which detects acceleration of an ego-vehicle, a radar which detects other vehicles around the ego-vehicle and provides a detection signal, and a processing unit having a processor and a memory, the processing unit being configured to: perform drive control for the ego-vehicle; calculate inter-vehicle distances to the other vehicles on the basis of the detection signal provided by the radar; determine a state of a traffic flow in a lane in which the ego-vehicle is driving, on the basis of the acceleration detected by the sensor and the calculated inter-vehicle distances; and switch the drive control when the determined state of the traffic flow is a state of a critical region which is present in a transition period from a free-flow state and a mixed flow state, wherein the free-flow state is a state in which the probability of occurrence of traffic congestion is low, and wherein the mixed-flow state is a state in which vehicles in a braking state and vehicles in an acceleration state of a vehicle are mixed, wherein the processing unit is further configured to: wherein the processing unit determines the state of the traffic flow on the basis of the correlation map.
