Disclosed is a driving support control device (ECU)capable of controlling a vehiclein accordance with any one selected from plural driving support modes by a driver. The driving support control deviceis configured to temporally repeatedly calculate a target traveling course (Rto R) along which the vehicleshould travel, and to, in a given one (preceding vehicle following mode) of the driving support modes, execute control of causing the vehicleto travel on and along the target traveling course, wherein the driving support control deviceis operable, in a situation where a current position of the vehicledeviates beyond a given distance dlaterally from the target traveling course, to, even when the driver selects the given driving support mode, prohibit transition to the given driving support mode.

Driving support control device

The driving support control device is configured to, when a preceding vehicle is detected (S: YES), be permitted to cause a transition to the preceding vehicle following mode, in response to a manipulation made by the driver to select the preceding vehicle following mode (S), and then control the vehicleto follow the preceding vehicle, and to, when edges of a traveling road are detected even though no preceding vehicle is detected (S: YES), be permitted to cause the transition to the preceding vehicle following mode, in response to the manipulation made by the driver to select the preceding vehicle following mode (S), and then control the vehicleto travel on and along a given target traveling course set based on the edges of the traveling road.
