Zusammenfassung:	PROBLEM TO BE SOLVED: To enable execution of control to suppress a dangerous situation for a vehicle without causing a driver to experience discomfort when an accelerator is erroneously operated, by setting an abnormality determination threshold for the accelerator operation to a value based on a degree of risk to the vehicle.SOLUTION: An accelerator position determination threshold is set to be lower when risk in the periphery of the vehicle is higher, intermediate when the risk is intermediate, and higher when the risk is lower (A). The accelerator opening is assumed to change shown by the solid line in (A). When the risk is higher, an abnormality determination is made upon the accelerator being lightly stepped on, and control is performed to suppress a dangerous situation. As the risk changes to intermediate and lower, the abnormality determination is made at a greater accelerator position (B). As a result, causing a driver to experience discomfort by execution/inexecution of control to suppress the dangerous situation can be suppressed.
