Automatic vehicle following system based on radar positioning and automatic vehicle following method thereof

Abstract

The invention discloses an automatic vehicle following system based on radar positioning. The automatic vehicle following system comprises a radar arranged on the front part of a vehicle, a processor used for processing radar data, an electromagnetic valve used for controlling the size of an accelerator and an electronic control brake mechanism. The automatic vehicle following system is characterized in that the electronic control brake mechanism comprises a servo motor, and the processor is respectively and electrically connected with the radar, the electromagnetic valve and the servo motor in the brake mechanism. According to the automatic vehicle following system, the radar is used for providing data for the processor in real time, the processor processes data and automatically controls actions of the electromagnetic valve or the electronic control brake mechanism according to the judgment, and the purpose of automatically driving a vehicle to follow a front vehicle is achieved. In addition, the invention provides an automatic vehicle following method of the system, and the method has the high operability and practicability.

Description

technical field [0001] The invention belongs to the field of locomotive automation control, and in particular relates to a vehicle automatic following system and a vehicle automatic following method based on radar positioning, which enable a vehicle to automatically follow a vehicle in front of it. Background technique [0002] With the development of urban modernization, automobiles are gradually popularized as people's daily means of transportation, followed by urban traffic congestion. In the "2008 Futian Index", the congestion cost of commuting to and from get off work in Guangzhou is 273.8 yuan per person per month, which is only the data calculated based on time and income, that is, time cost. As for the cost of fuel consumption in traffic jams alone, the most conservative estimate is that the annual cost of fuel consumption and traffic jams in Guangzhou is at least 1.8 billion yuan based on the current vehicle population of 1 million vehicles in Guangzhou. It is conc...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the purpose of the present invention is to provide a vehicle automatic follow system based on radar positioning. By installing the system on the vehicle, the driver does not need to manually control the accelerator and brake when the traffic is jammed. The accelerator and brake actions are completely controlled by the vehicle. The automatic control of the invented vehicle automatic following system is completed, and when an obstacle suddenly appears in front of the vehicle, or the vehicle in front brakes suddenly, the system of the present invention can quickly cut off the accelerator and perform the braking action, thereby solving the problem of fuel consumption of existing vehicles in traffic jams Large volume, manpower is required to control the vehicle, and automatic braking cannot be performed in case of emergency.
