Abstract
Abnormality determination for a driver is appropriately made in accordance with a peripheral state when lane keeping assist control is being carried out. When a no-driving operation state has continued for a period equal to or more than a set period, a driving support ECU determines whether or not a change inhibition condition set in advance in relation to a peripheral state of an own vehicle is satisfied. When the change inhibition condition is not satisfied, the driving support ECU sets a control mode of LKA to a “weaker mode” to decrease a control amount of the LKA. As a result, the own vehicle swerves in a lane, and a driver who has not fallen into an abnormal state can be prompted to carry out a steering wheel operation. Thus, it is possible to discriminate a driver who has fallen into the abnormal state and a driver who has not fallen into the abnormal state from one another. When the change inhibition condition is satisfied, the driving support ECU sets the control mode of the LKA to a “normal mode”.
