Embodiment Construction

[0081] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0082] Such as figure 1 As shown, the present invention provides a car rear-end collision prevention device based on front and rear cameras, which includes a perception layer, a decision-making layer, and an execution layer. The perception layer is composed of a front CCD camera, a rear CCD camera, and an ultrasonic sensor, which are used to obtain information on obstacles in front of the vehicle, information on obstacles behind the vehicle, and the time-to-time distance between obstacles and the vehicle body, and transmit the acquired perception information To the integrated controller ECU, after the controller ECU makes a decision, it transmits the signal to the executive layer, and the executive structure electronic accelerator pedal, electronic brake pedal, and electromag...

Abstract

The invention discloses a car tailgating prevention device based on a front camera and a rear camera. The device comprises a plurality of electromagnetic, pneumatic and hydraulic buffering devices which are arranged in the middle of a rear end panel on the tail portion of a car and in inner cavities on the two sides. The electromagnetic, pneumatic and hydraulic buffering devices comprise boss bases, telescopic cylinders, rubber blocks and safety air bags. The plane sides of the boss bases are fixedly connected with the tail portion of the car. One end of each telescopic cylinder vertically andhermetically sleeves a protrusion of the corresponding boss base. The rubber blocks are parallel and opposite to the protrusions of the boss bases and are hermetically connected with the other ends of the telescopic cylinders; the safety air bags are arranged in the rubber blocks. The electromagnetic, pneumatic and hydraulic buffering devices are arranged in the middle of the rear end panel on the tail portion of the car and in the inner cavities on the two sides, so that car collision and tailgating accidents are avoided, and the safety of car driving is greatly improved. The invention alsoprovides a control method of the car tailgating prevention device based on the front camera and the rear camera. Car conditions and road conditions are acquired, and work states of a brake pedal, an accelerator pedal and the electromagnetic, pneumatic and hydraulic buffering devices are determined on the basis of a BP neural network.

Description

technical field [0001] The present invention relates to the field of vehicle active safety, and more specifically, the present invention relates to a car rear-end collision prevention device based on front and rear cameras and a control method thereof. Background technique [0002] With the rapid development of economy and society, there are more and more vehicles on the road. As of the first half of 2018, the number of motor vehicles in the country has reached 319 million. The increase in the number of vehicles has led to more frequent traffic accidents. According to statistics, car rear-end accidents Accounting for more than 70% of the total number of accidents, the existing safety protection devices can no longer meet the needs of protecting vehicles from driving safely. [0003] At present, the driver mainly checks the driving conditions of the vehicles behind by observing the rearview mirror, and takes corresponding measures to avoid rear-end collisions. Some reduce th...
