Pattern projection system and method for car

Abstract

The invention discloses a pattern projection system for a car. The pattern projection system is internally arranged in the car. A specific static colorful pattern or dynamic logo pattern can be projected onto the road surface in front of the car according to the actual traveling road condition of the car, so that the temporary traffic dispersion effect and the visual forewarning effect on the carand pedestrians are achieved; under the severe weather situation, the effects of assisting traffic and ensuring safe intersection of traveling cars are achieved; and in addition, after used, the pattern projection system is stopped, the road surface recovers as before, and application is flexible and convenient.

Description

technical field [0001] The invention relates to an automobile projection pattern system, in particular to a projection system and a projection method which can select a projection pattern according to road condition information when the automobile is decelerating to ensure safe driving of the automobile. Background technique [0002] At present, the rapid increase in the number of cars and the sharp increase in traffic flow have put forward higher requirements for the safety and intelligent driving of cars. As a result, the demand for car-assisted safe driving has also begun to increase. When the car is running at night, in rainy and snowy weather, or in irregular lanes such as mountains and villages, there will often be pedestrians or animals crossing the road, especially in the case of poor road conditions, if there is no early warning And react quickly, prone to traffic accidents. [0003] In the prior art, the lighting of vehicles is generally used as a safety guarantee...

Problems solved by technology

When the car is running at night, in rainy and snowy weather, or in irregular lanes such as mountains and villages, there will often be pedestrians or animals crossing the road, especially in the case of poor road conditions, if there is no early warning And respond quickly, prone to traffic accidents

[0003] In the prior art, the lighting of vehicles is generally used as a safety guarantee in the case of poor vision, but when low beams are used, the driver's observation distance is insufficient; when high beams are used, pedestrians' sights will be affected, especially When multiple vehicles meet, pedestrians are more likely to make mistakes in judgment, which leads to tragic traffic accidents
