Abstract
A travel control device includes an automatic braking device that automatically brakes an own vehicle; and a driving support ECU configured to acquire information on one of a curvature and a curvature radius of a traveling road in front of the own vehicle, calculate a target vehicle speed of the own vehicle based on the information, and automatically decelerate the own vehicle by the automatic braking device so that the vehicle speed of the own vehicle becomes the target vehicle speed when the vehicle speed of the own vehicle exceeds the target vehicle speed, wherein the driving support ECU suppresses the execution of the automatic deceleration when it is estimated that the driver is going to overtake the preceding vehicle.
Claims7
A travel control device comprising:
- a camera configured to capture an image of surroundings of a target vehicle;
- an automatic braking device configured to automatically brake the target vehicle;
- and
- a processor configured to
- acquire information on one of a curvature and a curvature radius of a traveling road ahead of the target vehicle based on the acquired information,
- calculate a target vehicle speed of the target vehicle based on the information,
- determine whether a vehicle speed of the target vehicle exceeds the target vehicle speed, and
- in a case where a determination is made that the vehicle speed of the target vehicle exceeds the target vehicle speed, execute automatic deceleration on the target vehicle by the automatic braking device to control the vehicle speed of the target vehicle to reach the target vehicle speed,
- wherein the processor is configured to
- suppress execution of the automatic deceleration in a case where the processor estimates that a driver of the target vehicle traveling on a first lane is to overtake a preceding vehicle from a second lane adjacent to the first lane,
- determine, based on information that is acquired from the captured image, whether the target vehicle returns from the second lane to the first lane and travels in front of the preceding vehicle for a predetermined period or more, while suppressing the execution of the automatic deceleration, and
- terminate suppression of the execution of the automatic deceleration in a case where a determination is made that the target vehicle returns from the second lane to the first lane and travels in front of the preceding vehicle for the predetermined period or more.
