A first risk potential field for a risk avoidance control is a sum of a risk potential field in which a valley of a risk value extends in a lane longitudinal direction and a risk potential field in which the risk value is maximum at a position of an object and decreases as a distance from the object increases. The steering control is executed such that a vehicle approaches a first minimum point that is a minimum point of the first risk potential field and that is searched for in a first search range. When a plurality of first minimum point candidates is present in the first search range, the first minimum point candidate that is present in a direction away from a foremost object as viewed from a previous minimum point and is the closest to the previous minimum point is selected as the current first minimum point.

Driving support system

A driving support device performs steering control and deceleration control for avoiding an object which is detected in front of a host vehicle. The driving support device performs: calculating a target lateral distance which is a target of the steering control and which is a lateral distance between the host vehicle and the object when the host vehicle passes by the object; and increasing target deceleration which is a target of the deceleration control and which is deceleration of the host vehicle when the host vehicle passes by the object as a lateral distance restraint value which is obtained by subtracting the target lateral distance from a threshold value increases when the target lateral distance is less than the threshold value.

A road marking recognition device recognizes a road marking from an image acquired by imaging a road surface of a road on which a vehicle is traveling. The road marking recognition device includes: a storage unit configured to store a plurality of templates each of which corresponds to a corresponding one of plurality of feature portions of a road marking as a recognition target and between which a relative positional relationship is known; and a recognition unit configured to detect a second feature portion corresponding to a second template among the plurality of templates when the first feature portion is detected from the image.
