DRIVING SUPPORT SYSTEM

A driving support system installed on a vehicle includes: a roll back detection device configured to detect roll back of the vehicle; a stop-state detection device configured to detect stopping of the vehicle; a driving operation detection device configured to detect a driving operation performed by a driver of the vehicle; and a driving support control device configured to execute driving support control. The driving support control includes roll back suppression control that generates at least one of a driving force and a braking force to stop the vehicle when the roll back is detected. The driving support control device continues the roll back suppression control at least until the vehicle stops, even when the driving operation is performed during execution of the roll back suppression control.
