Vehicle safety assembly, method for improving vehicle safety performance and medium

Abstract

The invention relates to a vehicle safety assembly, a method for improving vehicle safety performance and a medium. The vehicle safety assembly comprises an engine hood jacking device and a front air bag module, the engine hood jacking device and the front air bag module can receive control signals, and the control signals are generated according to the collision state of a vehicle; the collision state of the vehicle comprises a first collision state and a second collision state; in the first collision state, a collision object of the vehicle is a pedestrian, a first control signal controls the engine hood jacking device to jack up an engine hood of the vehicle, and the front air bag is kept folded; and in the second collision state, the collision object of the vehicle is another vehicle, a second control signal controls the engine hood jacking device to jack the engine hood of the vehicle, and the front air bag is unfolded to the front of the vehicle.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a vehicle safety component, a method for improving vehicle safety performance, and a medium. Background technique [0002] In the field of vehicle safety, the requirements for road compatibility and protection of vulnerable road users (Vulnerable RoadUser, VRU) are getting higher and higher. The starting point of vehicle road compatibility is that for vehicle collision accidents, due to the differences in body height, weight, body structure, and even bumper height and shape of various vehicles on the road, one of the vehicles must have an active advantage in the collision accident. , one party has a disadvantage. How to protect your own safety and reduce the damage of the other party in a collision is the concept of vehicle road compatibility. In the 2021 version of the China-New Car Assessment Program (CNCAP), a penalty point requirement for road compatibility has been added. ...

AI Technical Summary

Problems solved by technology

[0006] However, the inventors found that the above solutions for improving road compatibility and protecting VRU cannot take into account both performances at the same time

Taking the front airbag as an example in the prior art, there are essential differences between the collision state of a vehicle and an obstacle compared with the collision state of a vehicle and a pedestrian, and the ability of an obstacle to withstand the impact of airbag deployment compared to a pedestrian. , therefore, regardless of internal pressure or size, the front airbags in the prior art for the protection of pedestrians are difficult to meet the road compatibility requirements of vehicles
