Embodiment 2

[0059] see image 3 , image 3 It is a schematic structural diagram of a pedestrian safety protection system provided by Embodiment 2 of the present invention. Embodiment 2 includes the following structure:

[0060] The pedestrian identification device 1 in front of the vehicle is used to identify the pedestrians in front of the vehicle through face recognition technology, so as to obtain the distance and angle of the pedestrians in front of the vehicle relative to the vehicle;

[0061] The vehicle speed obtaining device 2 is used to obtain the vehicle speed of the automobile;

[0062] The avoidance judging device 3 is used for determining that the vehicle speed is within the preset vehicle speed judgment range, and the acquired distance of the pedestrian relative to the car is within the preset valid distance range, and the acquired angle of the pedestrian relative to the car is within the preset valid angle range , then start the active avoidance device 4;

[0063] The ac...

Abstract

The invention discloses a pedestrian safety protection method. The pedestrian safety protection method comprises the steps that a pedestrian in front of a vehicle is recognized through a face recognition technology, and the distance and angle of the pedestrian in front of the vehicle relative to the vehicle are obtained; the speed of the vehicle is obtained; and when it is judged that the speed of the vehicle is within the preset vehicle speed judgment range, the obtained distance between the pedestrian and the vehicle is within the preset effective distance range, and the obtained angle of the pedestrian relative to the vehicle is within the preset effective angle range, active braking and active speed limiting of the vehicle are started. Correspondingly, the invention provides a pedestrian safety protection system. The pedestrian safety protection method and system can effectively achieve active avoidance before the vehicle collides with the pedestrian, ensure pedestrian safety and reduce accidents.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a pedestrian safety protection method and system. Background technique [0002] Pedestrians and cyclists are at high risk of injury on the road, with the majority of accidents involving pedestrians or cyclists colliding with the front of the vehicle, causing serious injury if their head hits the hood; and, Pedestrian collisions due to driver negligence or visual blind spots also occur from time to time. [0003] The prior art generally adopts passive protection measures for the above situation, such as setting up a safety net strategy, and after the collision between the pedestrian and the vehicle, the safety net installed on the vehicle is deployed to the extent that the pedestrian's head is hit and severely injured. [0004] The existing technology focuses on how to reduce the damage after a collision, and lacks an active protection strategy before the collision. Contents of th...
