Automobile rear-end collision prevention radar system

Abstract

The invention discloses an automobile rear-end collision prevention radar system. The system comprises a main vehicle, and a control device and an information acquisition system which are mounted on the main vehicle, the control device comprises a data processing system, an instruction execution system, an early warning system, a remote control system, a display device and a standby battery. The data processing system is composed of a high-speed microprocessor, a memory, an input / output interface, an analog-to-digital converter and a shaping and driving integrated circuit. Information input byan information acquisition device is quickly operated, processed and judged according to internal programs and data of the information acquisition device; an instruction is output to an instruction execution device; the data processing system calculates the collision time of the vehicle right behind and the main vehicle according to the real-time speed difference and the real-time interval distance of the two vehicles, according to the real-time distance and the real-time speed difference between the left vehicle and the right vehicle and the main vehicle, the distance between the time when the left vehicle and the right vehicle arrive at the tail side of the main vehicle at the real-time speed and the tail side of the main vehicle is calculated by combining the widths of the lanes of different levels and the basic widths of the vehicles, and then the calculated time and distance are transmitted to an early warning system for early warning.

Description

technical field [0001] The invention relates to an automobile electronic device, in particular to an automobile anti-rear collision radar system. Background technique [0002] With the continuous development of the social economy and the continuous improvement of people's living standards, the probability of people's travel is increasing, and the means of transportation used for travel are gradually transitioning from buses and subways to self-driving. With the continuous increase of traffic flow and the increasingly busy business dealings, the volume of vehicles on the road continues to increase, and the speed of vehicles continues to increase, so traffic accidents also continue to rise. In my country, more than 80% of traffic accidents are rear-end collisions. Rear-end collision accidents are generally caused by drivers deserting, low visibility in rainy and foggy weather, and inexperienced novices on the road. If an anti-rear-end collision device can be developed, not onl...

Problems solved by technology

The existing car anti-rear collision devices on the market all remind the driver of the car not to hit the vehicle in front, but there is no car anti-rear collision device that can not only remind the driver of the car in real time not to hit the car in front, but also remind the driver of the car behind Keep a safe distance from the vehicle in front
