Vehicular safety apparatus
First Claim
1. A vehicular safety apparatus comprising:
- determining means for determining a collision prediction level of a vehicle based on a relative position between the vehicle and an obstacle ahead of the vehicle;
storage means for storing an amount of brake operation by a driver at a point where the collision prediction level determined by the determining means exceeds a predetermined threshold, as a reference level; and
actuation control means for actuating the safety apparatus in accordance with an increase of the amount of brake operation of braking by the driver from the reference level stored in the storage means.

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.

20. A vehicular safety apparatus capable of performing a braking assist process, the vehicular safety apparatus comprising:
-
a storage device that stores a reference braking amount by a driver of a vehicle; a collision predicting device that determines a collision prediction level of the vehicle based on a relative position between the vehicle and an obstacle ahead of the vehicle, a braking amount sensor, the braking amount sensor determining a present braking amount by a driver of the vehicle; a brake control calculation device that receives a result of the determination made by the collision predicting device and sets a brake assist amount; a brake actuator that generates a brake assist force based on the brake assist amount set by the brake control calculation device, wherein; the brake control calculation device sets the brake assist amount based on a difference between the present braking amount and the stored reference braking amount, and the present braking amount is stored in the storage device as the reference braking amount for a next cycle of the braking assist process.
