Abstract
A vehicular safety apparatus of the present invention is one actuated according to a collision prediction level of a vehicle. The vehicular safety apparatus of the present invention is provided with a determining device for determining a collision prediction level on the basis of a relative position between a vehicle and an obstacle ahead of the vehicle; a storage for storing a amount of brake operation by a driver at a point where the collision prediction level exceeds a predetermined threshold, as a reference level; and an actuation controller for actuating the safety apparatus in accordance with an increase from the reference level. This prevents the actuation of the safety apparatus from being excessive in the case where an increase of the amount of brake operation is low. Furthermore, in the case of the increase being high, the actuation is controlled so as to fully bring out the performance of the safety apparatus. Therefore, the performance of the safety apparatus can be suitably demonstrated without causing the driver to feel odd.
