Drive assist device

摘要

A drive assist device includes a driver state detection unit that outputs an emergency evacuation start signal, an consent confirmation unit that inquires of the driver, whether or not emergency evacuation control to stop a vehicle at a safe position regardless of a driving operation of the driver is permitted and receives a reply with respect to the inquiry from the driver, and a control unit that performs the emergency evacuation control when the reply which permits the performing of the emergency evacuation control is received from the driver by the consent confirmation unit. The control unit alleviates conditions for performing a preventive drive assist in which the risk for the traveling of the vehicle is avoided during a period from the time of receiving the emergency evacuation start signal to the time of receiving the reply of permitting the performing of the control by the consent confirmation unit.
