Motor Vehicle Radio Frequency Safety Systems

Abstract

The invention discloses a motor vehicle radio frequency safety system. The motor vehicle radio frequency safety system includes: a radio frequency identification tag installed in the front vehicle; an antenna, a reading and writing device and a control device installed in the vehicle; the radio frequency identification tag and the antenna can exchange information through radio frequency; the radio frequency identification tag is used to receive The electromagnetic signal sent from the vehicle, and return the echo signal corresponding to the electromagnetic signal; the reading and writing device is used to send the electromagnetic signal to the radio frequency identification tag through the antenna, and receive the echo signal returned from the radio frequency identification tag; the control device, Connected with the read-write device, it is used to obtain the safety performance status information of the vehicle by using the electromagnetic signal sent by the read-write device and the echo signal received. The motor vehicle radio frequency safety system of the invention can measure the vehicle distance in real time and transmit the safety performance status information of the vehicle ahead, thereby improving the driving safety of the motor vehicle.

Description

technical field [0001] The invention relates to the field of safety equipment in the automotive electronics industry, in particular to a radio frequency safety system for motor vehicles. Background technique [0002] With the increasing enrichment of people's material and cultural life, the number of motor vehicles in our country is on the rise every year. Motor vehicles bring great convenience to people's travel, but also bring a lot of harm to the society. One is to cause urban traffic congestion, and the other is that motor vehicle accidents cause casualties and bring misfortune to many families. According to statistics, 50% of motor vehicle accidents are due to vehicle collisions caused by rear-end collisions. Article 80 of the Regulations on the Implementation of the Road Traffic Safety Law of the People's Republic of China stipulates that when a motor vehicle is driving on an expressway and its speed exceeds 100 kilometers per hour, it should keep a distance of more t...

Problems solved by technology

[0003] The applicant realizes that the existing technology has the following technical defects: the current judgment of vehicle distance largely depends on the driver's own driving experience. This method has a relatively large error when driving in bad weather or on the expressway, especially For novices who are not very skilled in driving, this is very detrimental to the safety of motor vehicles
