Car-following car with redundant puncture monitoring

Abstract

The invention discloses a following car with a redundancy tire burst monitoring function. The following car comprises a first tire burst monitoring device and a second tire burst monitoring device redundant with the first tire burst monitoring device, both the first and second tire burst monitoring devices are connected on an automatic driving analysis system, a following car state control device is connected on the automatic driving analysis system, the first tire burst monitoring device comprises a velocity sensor, a tire pressure monitoring device and an in-tire airflow velocity acquisition device, the second tire burst monitoring device comprises a road surface information acquisition device, a vehicle load acquisition device and a tire pressure acquisition device, a positioning device is further connected on the automatic driving analysis system, and a communication system communicating with the following car is further connected on the automatic driving analysis system. The following car has the redundancy tire burst monitoring function, reliable monitoring of tire burst is realized, fast response is adopted during tire burst, and occurrence of traffic accidents is avoided.

Description

technical field [0001] The invention relates to the field of car-following cars, in particular to a car-following car with redundant tire burst monitoring. Background technique [0002] Car-following is the driving state in which the vehicle behind follows the vehicle in front, that is, the vehicle in front and the vehicle behind achieve information communication, and the vehicle behind compares the parameters of the front and rear vehicles based on the information of the vehicle in front, and converts it into a driving plan for the vehicle behind to realize automatic driving. In automatic car-following driving technology, the car-following car drives according to the driving parameters of the vehicle in front. There will be many unexpected situations during the driving of the vehicle, such as: a tire blowout, and the consequences of a tire blowout during the driving process of the vehicle are very serious. In a car-following convoy, in order to accommodate more car-followi...

AI Technical Summary

Problems solved by technology

In a car-following convoy, in order to accommodate more car-following cars on a road with a certain distance, the safe driving distance between two adjacent vehicles can be shortened to 20 meters or even shorter, and the vehicle is exploded due to explosion during high-speed driving. It takes about 3 seconds for the car to lose its handling performance due to tires, which is basically consistent with the driving braking reaction time, and it is very important to realize the safety control of the following team in such a short distance. It only warns people when they are pregnant, and people's reaction speed is slow

And the situation of car blowout does not happen from time to time, the car is used for a long time, and the tire blowout monitoring device is prone to situations, that is, the monitoring of the blowout situation cannot be achieved.
