Abstract

The invention discloses an automatic detection system for tire blowout and undervoltage of an unmanned vehicle. The vehicle deviation detection module judges whether the vehicle is deviation; the vehicle body attitude abnormality detection module judges whether the body posture is abnormal; The detection module and the body posture abnormal detection module judge whether the tire is in an abnormal state of puncture or underinflation; after the alarm module detects the abnormal state information transmitted by the tire pressure detection module, it transmits the abnormal information to the remote platform, and at the same time controls the vehicle to stop safely . The advantage is that the detection system proposed in this patent does not require high-cost tire pressure monitoring sensors, and only needs to obtain existing information from the vehicle. The abnormal phenomenon of the attitude of the tire is monitored. At the same time, when a tire burst occurs, the driving direction can be corrected in time to prevent the vehicle from entering the reverse lane or leaving the road.

Description

technical field

[0001] The invention relates to the field of automatic driving technology and automobile safety technology, in particular to an automatic detection system and method for unmanned vehicle puncture / underpressure Background technique

[0002] In recent years, autonomous driving technology has developed rapidly. With the continuous improvement of vehicle safety performance requirements, the tire pressure of vehicle tires is an important consideration for vehicle safety performance, and tire pressure detection has become an essential part of ensuring vehicle safety. If the tire pressure is too low, the fuel consumption will increase, the steering wheel will be very heavy, easy to run sideways, the tire will be abnormally heated, the function of the cord and rubber will be reduced, the friction will be doubled, the temperature of the tire will rise sharply, and the strength will drop sharply, resulting in a blowout. If the consequences of a tire blowout are light,...

Embodiment Construction

[0027] Attached below Figure 1-3 The technology will be further described with specific examples to help understand the content of the present invention.

[0028] An automatic detection system for tire blowout and underpressure of an unmanned vehicle, including a vehicle deviation detection module, an abnormal body posture detection module, an abnormal tire pressure calculation module, and an alarm module;

[0029] The vehicle deviation detection module includes real-time acquisition of the reference track of the planning layer, vehicle position information and steering wheel angle data; the vehicle position information includes vehicle position coordinates and heading angle, and calculates the heading angle deviation between the center of mass of the vehicle and the reference track point Determine whether the vehicle is off-track;

[0030]figure 1 As shown, the vehicle deviation detection module obtains the current heading angle data through the vehicle's existing sensors,...
