Pedestrian protection safety system for vehicles and control method

Abstract

The invention discloses a pedestrian protection safety system for vehicles and a control method, and relates to the field of vehicle safety. The pedestrian protection safety system comprises an image acquiring device, an image processing device, a safety net and a controller. The image acquiring device is used for acquiring the images in front of the vehicles. The image processing device is used for judging whether pedestrians exist or not in front of the vehicles. The safety net is surrounds a front compartment of the vehicles and the side face of a passenger compartment after being unfolded. The controller is arranged to control the safety net to be unfolded when it is judged that pedestrians exist in front of the vehicles. The invention further provides the corresponding control method. The safety net is arranged, at the moment that the vehicles and the pedestrians collide and then drivers are thrown out of the vehicles, and the safety net is quickly unfolded between a vehicle wheel fender and an pillar A, so that protection is achieved between the ground and the heads of the pedestrians. The heads of the pedestrians are in contact with the safety net first, and then the pedestrians fall into the ground after a large amount of collision energy is buffered. Accordingly, the acute injury degree due to the hitting to the heads of the pedestrians is effectively lowered.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a vehicle pedestrian protection safety system and a control method. Background technique [0002] In road traffic, more and more attention has been paid to the safety of pedestrians. Accidents caused by hitting pedestrians account for a large proportion of all traffic accidents every year. While the victims lose economic benefits, they also suffer great physical and mental injuries. Therefore, more and more Leading enterprises and vehicle research institutions have conducted effective research on vehicle pedestrian protection devices. [0003] At present, most vehicle pedestrian protection devices take into account the pedestrian protection effect of the vehicle itself, that is, the protection of the injury caused by the assumption that the pedestrian hits the vehicle. For example, the pedestrian airbag is used to absorb the energy when the pedestrian hits the vehicle. Deploy the a...

Problems solved by technology

[0004] However, in actual pedestrian-vehicle traffic accidents, there are many uncertainties in the motion posture of pedestrians when they collide with vehicles, which leads to the vicious death of pedestrians who are thrown out of the vehicle and hit the ground with their heads in many cases.
