Problems solved by technology
[0005] After the engine cover pops up, on the one hand, the instrument panel will give an alarm, causing the driver to dare not continue to drive. On the other hand, most current active pedestrian protection engine covers use an irreversible gunpowder pop-up system, which needs to be replaced with a new one. The maintenance price On the high side

Embodiment
[0053] In the prior art, whether the active hood pop-up device is detonated is judged by the collision sensor installed at the position of the front bumper. The vehicle ECU can send an ignition command to the jack according to the received collision signal, and the jack After the detonation, lift the hinge of the cover, so that the rear end of the cover bounces up in a slope shape, buffering the impact on the pedestrian's head, and at the same time avoiding the pedestrian's secondary injury to the glass.
[0054] Since the collision sensor at the front bumper cannot identify the target, when the vehicle hits a target other than a pedestrian, as long as the collision sensor at the front bumper generates a collision signal similar to hitting a person's leg, the engine can be triggered. The cover lifter pops up. At present, most active pedestrian protection bonnets use an irreversible gunpowder pop-up system, which cannot be reused. After popping up, a new hood needs to be replac...

The invention discloses a method, device and equipment for preventing an engine hood from bouncing by mistake and a storage medium. The method comprises the steps that a road type corresponding to a vehicle driving road is obtained; if the road type is a first road type, a jacking device is communicated with a vehicle electronic control unit; when the jacking device is communicated with the vehicle electronic control unit, the jacking device can receive a hood bouncing signal sent by the vehicle electronic control unit so as to allow the engine hood to bounce; if the road type is a second roadtype, the jacking device and the vehicle electronic control unit are disconnected; and when the jacking device is disconnected with the vehicle electronic control unit, the jacking device does not respond to a hood bouncing signal sent by the vehicle electronic control unit. According to the invention, the occurrence probability of the explosion of the jacking device caused by the collision between the non-pedestrian target object and the vehicle can be reduced, so that the utilization rate of the active engine hood bouncing device is optimized.
Description
technical field [0001] The present invention relates to the technical field of pedestrian protection, in particular to a method, device, equipment and storage medium for preventing an engine cover from popping up by mistake. Background technique [0002] In a car-pedestrian crash, the vehicle components that collide with the pedestrian are usually the front bumper first and then the hood leading edge. During this process, the lower limbs accelerate toward the direction of the vehicle under the action of the collision force, and the upper body rotates relative to the vehicle while accelerating toward the direction of the vehicle. Finally, the front edge of the hood and the hood collide with the pelvis and chest, respectively, while the head collides with the hood or the front windshield area. Pedestrian head injuries are the leading cause of pedestrian serious injury or death, and the hood area is the primary location for pedestrian head injuries. [0003] In order to achie...
