Abstract

The invention belongs to the technical field of automobile collision safety, and relates to a novel pedestrian detection collision pre-judgment protection system. The system comprises a pedestrian recognition camera, a radar sensor, a pedestrian confirmation unit, a distance confirmation unit, a collision pre-judgment unit, an air bag detonation control unit and a pedestrian protection air bag. The pedestrian recognition camera is connected with the pedestrian confirmation unit. The radar sensor is connected with the distance confirmation unit. The pedestrian confirmation unit and the distance confirmation unit are respectively connected with the collision pre-judgment unit and transmit respective signals to the collision pre-judgment unit; an ignition detonation demand signal sent by the collision pre-judging unit is transmitted to the air bag detonation control unit; and the airbag detonation control unit sends an ignition instruction and transmits the ignition instruction to the pedestrian protection airbag. The system has the advantages that the possible collision condition of the pedestrian is pre-judged, the pedestrian protection air bag is pre-judged and detonated in advance, and the purpose of protecting the pedestrian is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile collision safety, and relates to a novel pedestrian detection collision prediction protection system. Background technique [0002] The existing pedestrian protection technology is to install a collision sensor on the front of the vehicle. When the vehicle has collided, the collision sensor will send a collision signal to the airbag control unit after the collision. The airbag control unit will analyze and process the signal after receiving the signal, and then send out The detonation signal detonates the pedestrian protection airbag, and protects pedestrians from secondary injuries by detonating the pedestrian protection airbag and other methods. [0003] The notification number is CN1315675C patent, which relates to a pedestrian protection device for protecting pedestrians collided by a moving vehicle by lowering the front of the vehicle and guiding the pedestrian on the front hood of the veh...
