Vehicle anti-scraping system and method for parking lot

Abstract

The invention discloses a vehicle anti-scraping system and method for a parking lot. The method comprises steps of S11, initializing the anti-scraping system; S12, judging whether the pressure value detected by at least one pressure sensor is in a preset threshold range or not, and if not, continuing to execute the step S12; if yes, executing the step S13; S13, generating a driving track according to the monitored pressure sensor, obtaining an air bag surface corresponding to the driving track based on a preset distance reference table, obtaining the distance between the position in the driving track and the air bag surface, judging whether the obtained distance is greater than a first safety distance or not, if yes, not processing, and continuing to execute the step S12; if not, executing the step S14; S14, whether the obtained distance is larger than a second safety distance or not being judged, if yes, a lamp panel arranged in an air bag changing color and flickering, and vehicle scraping being avoided; if not, the lamp panel arranged in the air bag changing the color and flickering, the air bag being deflated and contracted, and the vehicle being prevented from being scratched.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a vehicle anti-scratch system and method for a parking lot. Background technique [0002] There are many load-bearing columns in the indoor parking garage. If the car is close to the columns when making a sharp turn in the parking garage, it will often cause scratches. Although the front of the car has a certain distance from the pillar and can turn smoothly, the rear of the car can't get through, which is caused by the difference between the inner wheels. The inner wheel differential is the difference between the turning radius of the inner front wheel and the turning radius of the inner rear wheel when the vehicle is turning. Through calculation, it can be seen that for a model with a wheelbase of 3 meters, the inner wheel difference is about 1.1 meters when the front inner wheel steering angle is 40 degrees (the steering wheel is dead). In general, the inner wheel diff...

However, its thickness is only about 5 mm, which cannot effectively prevent scratches, and the passive warning reflective strip has limited effectiveness when the lights are not turned on. In fact, when the car enters the garage during the day, it often forgets to turn on the headlights

[0004] For example, the patent with the publication number CN211691704U discloses a parking lot protective device, including a protective body, the protective body is installed on the surface of the protected object, and the parking lot protective device includes a controller, a distance sensor, an air bag, a valve, a pressure sensor, a fan and a buzzer. Although the above-mentioned patent can achieve the purpose of anti-scratch by setting the airbag in the protective body, it uses a distance sensor. When pedestrians, animals or others pass by, the corresponding distance will also be detected. At this time, the airbag also will be ejected, causing unnecessary trouble to pedestrians or others; and passing the distance sensor in the parking lot will cause detection errors
