TRAVEL CONTROL DEVICE AND TRAVEL CONTROL METHOD

摘要

A travel control device includes rear obstacle detection sensors; side obstacle detection sensors; a warning unit providing warning about an obstacle detected by the sensors; and a control unit controlling the warning unit so that the warning is provided if a distance to an obstacle detected by the rear obstacle detection sensors is equal to or less than a first risk, or if a parameter based on a distance to the obstacle detected by the sensors is equal to or less than a second risk. If the parameter based on the distance to the obstacle detected by the sensors is greater than the second risk, the control unit increases a first warning threshold until a hold time elapses after the sensors become unable to detect the obstacle.

1. A travel control device comprising:
a rear obstacle detection unit which detects an obstacle entering an area rearward of a vehicle, and a distance to the obstacle; a side obstacle detection unit which detects an obstacle entering a predetermined lateral side detection region including an area laterally rearward of the vehicle, and a distance to the obstacle; a rearward movement preparation detection unit which detects the vehicle preparing to move rearward; a warning unit which provides warning about the obstacle detected by the rear obstacle detection unit or the side obstacle detection unit; and a control unit which controls the warning unit so that the warning is provided, if the distance to the obstacle detected by the rear obstacle detection unit is equal to or less than a first warning threshold, or if a parameter based on the distance to the obstacle detected by the side obstacle detection unit is equal to or less than a second warning threshold, wherein, if the rearward movement preparation detection unit detects the vehicle preparing to move rearward and the parameter based on the distance to the obstacle detected by the side obstacle detection unit is greater than the second warning threshold, the control unit increases the first warning threshold until a hold time elapses after the side obstacle detection unit becomes unable to detect the obstacle.
