Abstract
A collision obstacle discrimination device for a vehicle has at least one upper detection unit arranged between a bumper and side members and at least one lower detection unit disposed at a lower side of the upper detection unit. The upper detection unit detects at least a component of a side-member extension direction of a collision energy when an obstacle collides with the bumper. The lower detection unit detects a collision energy which is closer to the ground than the component of the side-member extension direction of the collision energy detected by the upper detection unit. A discrimination unit is further provided to sort-distinguish the obstacle by comparing the collision energy detected by the upper detection unit and that detected by the lower detection unit.
Claims18
A collision obstacle discrimination device for a vehicle, comprising:
- at least one upper detection unit which is arranged between a bumper and side members of the vehicle,
- the upper detection unit detecting at least a component of a collision energy when an obstacle collides with the bumper, the component being in an extension direction of the side member;
- at least one lower detection unit which is disposed at a lower side of the upper detection unit with respect to a direction perpendicular to a ground,
- the lower detection unit detecting a collision energy which is closer to the ground than the component of the side-member extension direction of the collision energy detected by the upper detection unit;
- and
- a discrimination unit which sort-discriminates the obstacle by comparing the collision energy detected by the upper detection unit and that of the lower detection unit.
