Embodiment 1

[0013] The GPS information parameters are output to the speed calculation module 2 by the GPS navigation module 1, and the instant average speed is obtained by the calculation value of the speed calculation module 2 and input to the central processing unit 3. At the same time, the environment sensing module 5 selects the laser distance measuring module according to the environmental conditions at that time 8. One or two of the ultrasonic ranging module 9, the infrared ranging module 6, and the radar speed and distance module 7 measure the distance of the driving direction, and input the speed signal and the distance signal to the information processing module 11, the central processing unit 3, or It is to select the image acquisition module 10, the image processing module 12 to input the information processing data into the central processing unit 3, and the central processing unit sends an early warning signal to the early warning signal module 4 and the display output 14, the ...

Embodiment 2

[0015] The GPS information parameter is output to the speed calculation module 2 by the GPS navigation module 1, and the instant average speed is input to the central processing unit 3 by the calculation value of the speed calculation module 2. Carry out ranging, and speed signal and distance signal input information processing module 11, central processing unit 3, central processing unit sends early warning signal to early warning signal module 4 and display output 14, display according to the calculation result of speed, distance early warning value formula screen 17, at this moment, the LCD display is switched to a distance warning pattern, and the warning power amplifier 22, the warning speaker 21 and the car power amplifier 18, the L speaker group 19, and the R speaker group 20 send out voice and warning tone, prompting the driver to decelerate. , when the intelligent vehicle-mounted GPS navigation collision avoidance warning system detects that the speed and distance are ...

Embodiment 3

[0017] The GPS information parameter is output to the speed calculation module 2 by the GPS navigation module 1, and the instant average speed is input to the central processing unit 3 by the calculation value of the speed calculation module 2. Carry out ranging, and speed signal and distance signal input information processing module 11, central processing unit 3, central processing unit sends early warning signal to early warning signal module 4 and display output 14, display according to the calculation result of speed, distance early warning value formula Screen 17, at this moment, liquid crystal display screen shows and switches to distance warning pattern, and early warning power amplifier 22, early warning loudspeaker 21 send out voice and warning tone, prompts the driver to carry out deceleration processing, and intelligent car GPS navigation anti-collision early warning system detects speed, When the distance is at a safe value, the LCD display is switched to a navigat...

Abstract

The invention discloses an intelligent vehicle-mounted GPS (global positioning system) navigation anti-collision warning system which consists of a GPS navigation module, a speed computation module, a central processing unit, an early warning signal module, an environment sensing module, an infrared distance measuring module, a radar speed distance module, a laser distance measuring module, an ultrasound distance measuring module, an image collecting module, an information processing module, an image processing module, a tail warning device, an audio video system, a display screen and an early warning power amplifier, wherein the speed is detected by the GPS, and the distance is detected by the distance measuring module, dangers which can cause tailgating at the front and at the back of a vehicle can be founded in time, so that a driver can be warned to travel normally and drive safely, functions of GPS navigation and audio video are realized, and no part of a vehicle control system needs to be changed.

Description

technical field [0001] The invention belongs to the field of automobile anti-collision early warning, in particular to an intelligent vehicle-mounted GPS navigation anti-collision early warning system. Background technique [0002] With the development of the automobile industry, the speed of automobiles is getting faster and faster, and road traffic accidents have become a worldwide social problem. Among them, the proportion of collision accidents is about 80%, so the research on automobile collision avoidance has become a worldwide topic. According to the analysis of automobile traffic accidents by experts, 80% of the traffic accidents are caused by the driver's untimely response and improper handling. Among them, 65% belong to the accident caused by automobile rear-end collision. On urban roads, drivers tend to relax their vigilance due to the slow speed of the vehicle, and rear-end collision accidents caused by being too close to the vehicle in front often occur. Altho...
