A control unit performs a lane departure suppression control when a host vehicle is about to depart from a traveling lane. The control unit determines whether a low impact collision has occurred. The control unit performs a secondary collision damage mitigation control when the low impact collision is determined to have occurred while the lane departure suppression control is being performed.

Driving assistance apparatus

A control unit determines whether a rapid acceleration pedal depression operation has been performed. The control unit determines whether a low impact collision has occurred. When it is determined that the rapid acceleration pedal depression operation has been performed and the low impact collision has occurred, the control unit executes a secondary collision damage mitigation control. Consequently, the secondary collision damage mitigation control can be appropriately executed even when a collision that does not cause an air bag to be inflated has occurred.

A driving assist apparatus comprises a driver monitor sensor which detects a state of a driver of an own vehicle installed with the driving assist apparatus. The apparatus determines whether the driver is in a drowsy state, based on the state of the driver detected by the driver monitor sensor. The apparatus determines that a light collision occurs when a light collision determination condition that at least one collision index value representing a level of a collision of the own vehicle is larger than a light collision determination threshold at which an airbag is not developed, is satisfied. The apparatus executes a secondary collision damage mitigation control to apply a braking force to the own vehicle or limit a driving force applied to the own vehicle when determining that the driver is in the drowsy state, and the light collision occurs.

A roll over detector for a vehicle is disclosed, which includes a roll over phenomenon detecting circuit that detects a roll over phenomenon of the vehicle based on a relationship between at least a type of physical quantity representative of a roll state of the vehicle and a predetermined threshold; a reacting roll phenomenon detecting circuit that detects a reacting roll phenomenon of the vehicle based on a predetermined criterion, which reacting roll phenomenon occurs in reaction to the roll phenomenon in an opposite direction; and a threshold changing circuit that changes the predetermined threshold from a first threshold to a second threshold so that the roll over phenomenon becomes difficult to be detected by the roll over phenomenon detecting circuit if the reacting roll phenomenon is detected by the reacting roll phenomenon detecting circuit.
