Safety early warning system for eliminating hidden danger of difference of radius between inner wheels of vehicle

Abstract

The invention relates to a safety early warning system for eliminating hidden dangers of vehicle inner wheel differences, and belongs to the technical field of vehicle operation safety. The system consists of an early warning system inside the cab and an early warning system outside the cab. By using the head-up display (HUD) technology, the driver can intuitively see the situation in the dangerous area of ​​the inner wheel difference, and the driver does not have to look down at the display screen, reducing driving fatigue; the buzzer at the rear end of the car sounds And the way that the LED lights at night illuminate the dangerous area of ​​the inner wheel differential can effectively remind pedestrians and vehicles to pay attention to the dangerous area of ​​the inner wheel differential during the day and night. The early warning inside and outside the cab in the safety early warning system is accurate, so that the vehicle can turn safely and avoid traffic accidents. Therefore, the safety early warning system has played a huge role in eliminating hidden dangers of vehicle inner wheel differential.

Description

technical field [0001] The invention belongs to the technical field of vehicle operation safety, and in particular relates to a safety early warning system for eliminating hidden dangers of vehicle inner wheel differential. Background technique [0002] With the continuous growth of the national economy, China's vehicle industry has developed rapidly, which has brought great convenience to people's life, but the hidden danger of inner wheel difference in vehicles has caused a lot of property loss or personal injury to people. The so-called inner wheel difference is the difference between the turning radius of the front inner wheel and the turning radius of the rear inner wheel when the vehicle is turning, that is, the movement trajectories of the front and rear wheels do not coincide when the vehicle is turning. The longer the vehicle body is, the greater the inner wheel difference will be. For large vehicles, the inner wheel difference can reach more than 2 meters due to th...

Problems solved by technology

[0004] Analyze the existing inner wheel differential warning system, which mainly serves as a reminder to the driver, but does not have any warning function for pedestrians or other obstacles located in the inner wheel differential dangerous area, so there is a problem of insufficient two-way reminder; Moreover, the driver needs to lower his head frequently to observe the LCD screen installed in the cab, which will obviously distract the driver's attention, thereby causing great danger.

In addition, the start of some early warning systems requires that the driver toggle the steering switch, which depends on the driver's driving habits to a certain extent. Sometimes the driver does not toggle the steering switch when turning, so no early warning will be generated at all. Therefore, the traditional Whether the early warning system is effective or not is largely due to human factors; the detection area of ​​the laser radar detection device installed on both sides of the truck body is approximately rectangular, while the dangerous area of ​​the inner wheel difference is fan-shaped, which seriously increases the possibility of false alarms; for The early warning system equipped with LED lights, due to the relatively strong daytime light, its projection area is not obvious, so the role of the early warning system cannot be fully utilized
