Embodiment Construction

[0027] The following are specific embodiments of the present invention, and further describe the technical solution of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0028] Such as Figure 1-2 As shown, the active protection system for preventing the secondary injury of pedestrians includes: the collision sensor 2 is closely attached to the inner side of the vehicle bumper, and is used to detect the collision acceleration signal of the collided part when the vehicle collides; Information such as local collision acceleration and collision force. This system can also be matched with sensors such as vehicle-mounted electromagnetic wave mines, laser radars, and vehicle-mounted cameras 3 to facilitate the vehicle-mounted control unit 1 to make more accurate capture judgments. For example, the vehicle-mounted control unit 1 is also connected with a camera 3 for detecting image data of environment...

Abstract

The invention provides an active protection system and a method thereof for preventing secondary damage of pedestrians, belongs to the technical field of automobiles and solves the problem that pedestrians are not efficiently protected when vehicles and pedestrians collide in the prior art. The active protection system comprises a vehicular control unit, a collision sensor, an automobile forward sensor, a pedestrian protection air bag device and a capture device. The method includes steps of A, detecting collision acceleration of the collision sensor, and detecting property and prior-collision motion states of an object to be collided by the automobile forward sensor; B, controlling the pedestrian protection air bag device to inflate and unfold an air bag when collision intensity exceeds the threshold; C, predicting flight path of the object according to the collision strength and the collision position, so as to correspondingly simulate moving track parameters of a current capture net and controlling the capture device to capture and wrap the object according to the moving track parameters of the current capture net. By the active protection system and the method thereof, secondary damage to the pedestrians can be effectively prevented, and safety of the pedestrians is protected to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an active protection system and a method thereof for preventing secondary injuries of pedestrians. Background technique [0002] Among the people who died in road traffic accidents all over the world in recent years, pedestrians, cyclists, and motorcyclists accounted for 60% of the casualties in traffic accidents. Above-mentioned crowd is the vulnerable group in the traffic accident on the road. Although the current international mainstream car companies are trying to make a more reasonable design for pedestrian safety. For example, the bumper, engine cover, and front windshield are made relatively flat and soft. It has a certain protective effect on extremely high-speed collisions, but it has little effect on medium and high-speed collisions. Later, the design of installing pedestrian protection airbags appeared. [0003] For example, the Chinese patent document discloses a...
