The invention discloses an automobile chassis automatic lifting method and system based on road surface accumulated water, and belongs to the technical field of road surface accumulated water. According to the invention, a vehicle-mounted front laser radar is used for continuously scanning the road section ahead, the current road condition can be obtained in real time, especially on the road section with accumulated water in rainy days, infrared light and blue and green light can be emitted through the laser radar, after the two beams of laser reach the interface of air and the water surface, the 1064nm infrared laser is reflected and returned by the water surface, the 532nm blue-green laser penetrates through the water surface to reach the road surface, is reflected by the road surface, and then penetrates through the water surface to return. The accumulated water depth information is obtained in real time by calculating the echo time difference, then a domain controller is used for processing the accumulated water depth information, then a lifting signal is sent to the chassis lifting device, lifting of the chassis is automatically controlled, manual operation of a driver is not needed, the workload of the driver is reduced, and the driving safety of the driver is ensured.
Description
technical field [0001] The invention belongs to the technical field of road surface water, and in particular relates to an automatic lifting method and system for an automobile chassis based on road surface water. Background technique [0002] When a car passes through a road section with deep water, the engine or other important components are often damaged due to water ingress in the engine room, which poses a great safety hazard to the driver's driving. Every year, a large number of soaked cars flow into the second-hand car market, which adds a lot of car buying traps to second-hand car transactions. In order to avoid this situation, it is necessary to equip the car with a device that can lift the chassis. [0003] Automobile chassis lifting devices are currently mainly divided into pneumatic lifting and hydraulic lifting types, and the principles of the two are relatively similar. At present, most high-end vehicles have been equipped with pneumatic chassis lifting syst...
