Initiative collision-prevention device for automatic driving type passenger vehicle

Abstract

The invention relates to an active anti-collision device for a self-driving passenger vehicle, comprising a positioning base, a buffer protection layer, an elastic telescopic rod, a rotating drive mechanism, an ultrasonic distance measuring device, a laser distance measuring device, a pressure sensor, a displacement sensor, and an angle sensor And the control circuit, the positioning base is embedded in the outer surface of the front and rear of the car, the buffer protection is connected to the front surface of the positioning base through elastic telescopic rods, the pressure sensor is embedded in the buffer protection layer, the displacement sensor is installed on the positioning base, and the angle sensor is installed In the rotary drive mechanism, the ultrasonic distance measuring device and the laser distance measuring device are respectively slidingly connected to the side surface of the positioning base through slide rails. On the one hand, the invention has good distance measuring and positioning operation ability, which is helpful to improve the obstacle avoidance and anti-collision ability during vehicle operation; ability.

Description

technical field [0001] The invention relates to a safety protection device, in particular to an active anti-collision device for a self-driving passenger vehicle. Background technique [0002] At present, in the operation of vehicles, especially during the operation of passenger vehicles, due to the high speed of the vehicle and the heavy load of the vehicle, it is easy to cause the braking ability of the vehicle to decrease and the braking distance to increase. Collision accidents between vehicles and obstacles, pedestrians, etc. caused by untimely movement, seriously threaten the driving safety and the personal and property safety of the people in the vehicle. The obstacle avoidance system realizes the vehicle's early detection of obstacles, early warning and early braking. Although this method can effectively realize the vehicle's braking and obstacle avoidance in a long-distance range, avoiding vehicle collisions, but Due to the failure of the braking system or the sudd...

Problems solved by technology

[0002] At present, in the operation of vehicles, especially during the operation of passenger vehicles, due to the high speed of the vehicle and the heavy load of the vehicle, it is easy to cause the braking ability of the vehicle to decrease and the braking distance to increase. Collision accidents between vehicles and obstacles, pedestrians, etc. caused by untimely movement, seriously threaten the driving safety and the personal and property safety of the people in the vehicle. The obstacle avoidance system realizes the vehicle's early detection of obstacles, early warning and early braking. Although this method can effectively realize the vehicle's braking and obstacle avoidance in a long-distance range, avoiding vehicle collisions, but Due to the failure of the braking system or the sudden appearance of obstacles on the vehicle's running line, once a collision occurs, the current obstacle avoidance system cannot effectively absorb and slow down the kinetic energy of the collision, resulting in vehicles and obstacles being damaged due to collisions. And the damage that causes can not get effective environment, thereby causes the harm that collision accident causes consequence to add, is unfavorable for forming safety, therefore for this problem, urgently needs to develop a kind of brand-new anti-collision device for vehicle, to satisfy actual use needs
