VEHICLE TRAVEL SUPPORT DEVICE, VEHICLE, AND VEHICLE TRAVEL SUPPORT PROGRAM

摘要

Provided are a vehicle travel support device capable of continuing operation even when the lane mark recognition accuracy decreases, and the like. In a vehicle travel support device (10), the degree of control of the operation of a steering gear (14) or the like is set higher as the reliability of a lane mark is higher. In a state in which the reliability of a travel area demarcated by the lane mark is high, the traveling of a vehicle (1) in such a manner that the vehicle (1) does not get out of the travel area is relatively strongly or actively supported. Meanwhile, the degree of control of the operation of the steering gear (14) or the like is set lower as the reliability of the lane mark is lower. In a state in which the reliability of the travel area demarcated by the lane mark is low, the traveling of the vehicle (1) in such a manner that the vehicle (1) does not get out of the travel area is relatively weakly or passively supported.
