Embodiment 1

[0015] The car-following car tire blowout monitoring device includes an automatic driving control analysis system for realizing car-following driving, judging and analyzing the tire blowout state, and a state control device for controlling the driving state of the car. The first tire burst monitoring device and the second tire burst monitoring device with a different monitoring principle from the first tire burst monitoring device.

[0016] During the driving process of a car, the safe driving distance between two adjacent vehicles is 50 meters or even farther. With the increase of the number of existing private cars, the roads are becoming more and more congested, and the two cars in motion cannot reach the distance at all. To this distance, the problem can be alleviated by car-following technology. The present invention has been improved on the basis of the existing car-following convoy, that is, two redundant tire burst monitoring devices are added on the car-following car,...

Embodiment 2

[0018] On the basis of the foregoing embodiments, this embodiment is refined as follows, that is, the first tire blowout monitoring device includes an airflow velocity sensor in the tire, a first tire pressure sensor and a speed sensor. When the car is running, gas flows in the tires. The first tire blowout monitoring device in this embodiment detects the flow of gas in the tire to determine the blowout condition. The airflow velocity sensor in the tire, the first tire pressure sensor and the speed sensor respectively monitor the airflow velocity in the tire, the tire pressure of the tire and the running speed of the vehicle, and transmit them to the automatic driving control analysis system. There is a certain relationship between the air pressure and the airflow velocity in the tire. If the airflow velocity in the tire is abnormal, the automatic driving control analysis system will judge the tire burst and immediately control the state control device to control the driving c...

Embodiment 3

[0020] In this embodiment, when a tire blows out in the above-mentioned embodiment, the following car with a blown tire can take deceleration, change lanes, etc., that is, the automatic driving control analysis system controls the brakes, steering wheel and turn signals to process; When the vehicle is decelerating, in order to continue to follow the vehicle behind, the vehicle behind can change lanes, that is, control the brakes, steering wheel and turn signal; when the vehicle with a flat tire changes lanes, the vehicle behind can still maintain the same lane. .

[0021] The first tire blowout monitoring device and the second tire blowout monitoring device also include a signal processing circuit.

[0022] The second tire blowout monitoring device in this embodiment judges the blowout condition based on the relationship between the tire pressure and the unloaded tire pressure. The tire pressure sensor and the pressure sensor monitor the air pressure and wheel pressure in the...

Abstract

The invention discloses a following automobile tire burst situation monitoring device. The following automobile tire burst situation monitoring device comprises an automatic driving control and analysis system and a state control device, as well as a first tire burst monitoring device and a second tire burst monitoring device, wherein the automatic driving control and analysis system is used for achieving following driving and used for judging the tire burst state according to tire pressure data, pavement information and weight of an automobile self; the state control device is used for controlling the running state of the automobile; the first tire burst monitoring device and the second tire burst monitoring device are both connected with the automatic driving control and analysis system; the monitoring principle of the first tire burst monitoring device is different from that of the second tire burst monitoring device. According to the following automobile tire burst situation monitoring device, two tire burst monitoring devices of different detection principles are adopted to monitor the redundancy of tire burst situation of the automobile, and the response to tire burst monitoring is fast.

Description

technical field [0001] The invention relates to the field of safety control of a car-following car, in particular to a tire blowout condition monitoring device for a car-following car. 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...
