Abstract

A travel control device for a vehicle includes a vehicle speed detector that detects a vehicle speed of the vehicle, a recessed portion detector that detects a position and a length of a recessed portion present on a road surface in front of the vehicle, a suspension controller that controls suspension devices provided between a vehicle body and wheels and can change a distance between the vehicle body and the wheels in an up-and-down direction, and a determiner that determines whether the wheel can pass over the recessed portion based on the vehicle speed and the length of the recessed portion. In a case where the determiner determines that the wheel can pass over the recessed portion, the suspension controller retracts the suspension device corresponding to the wheel when the wheel reaches an edge of the recessed portion.
