Description
Technical field
The present invention relates to field of automobile safety, be specifically related to a kind of bumper/spoiler terrain clearance control system and method thereof.
Background technology
Because the bumper/spoiler terrain clearance of car is different with the bumper/spoiler terrain clearance of sport utility vehicle SUV, in car collision or rear-end collision, frequent generation car pierces at the bottom of SUV car, cause damaged vehicle serious, as American Highway security insurance association (IIHS) once chose 7 groups of cars under same brand and SUV especially, carry out the low speed collision test of speed per hour 10 miles (about 16 kilometers), the collision damage that different bumper height causes is investigated by simulating the common low speed scene that knocks into the back, result shows: car front-body situation about getting under SUV bumper/spoiler can cause engine compartment cover and head light etc. all can be badly damaged, and when SUV knocks into the back car, the bumper/spoiler of SUV generally can cause damage to parts such as car tail railway carriage or compartment, taillights, the bumper/spoiler of car also easily damages the parts such as water tank, radiator fan of SUV.
The patent (CN201980173U) of Henan Huangma Vehicle Co., Ltd. discloses a kind of rear bumper of adjustment height for the rear bumper of cargo plane motor-car, should be less than or equal to 55 centimetres of current required standard regulations based on cargo plane motor-car rear bumper terrain clearance, the situation that rear bumper terrain clearance is higher is needed for the special occasions (as coal works needs the place of unloading) beyond highway, a kind of connecting device of design, its cross section is connecting panel or the flush type connecting panel of U-shaped, mounting hole is vertically interval with 3 at connecting device, rear bumper is arranged on connecting panel by mounting hole, but the obvious drawback of the existence of this patent: can only rely on when adjustment rear bumper height and regulate manually, namely when needs regulate bumper height, must adopt and manually unload bumper body, be mounted to again on the mounting hole of higher position.
Be different from air truck motor-car, car is because appearance and modeling requirement, bumper body is not directly installed on body exterior usually, manually bumper body is changed as adopted, remove and install very loaded down with trivial details, and the mode of manual regulation is applicable to this car active Automatic adjusument mode under steam, this is nonsensical for reducing the loss in vehicle collision.
Summary of the invention
In view of this, the invention provides a kind of bumper/spoiler terrain clearance control system and method thereof.
