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.
本发明公开了一种基于路面积水的汽车底盘自动升降方法及系统,属于路面积水技术领域。本发明利用车载前置激光雷达持续对前方路段进行扫描,可以实时获得当前路况,特别是在雨天有积水路段,可以通过激光雷达发射红外光和蓝绿光,这两束激光到达空气与水面的分界面后,1064nm红外激光被水面反射返回,532nm蓝绿激光则穿透水面到达路面,后被路面反射,再穿过水面返回;通过计算回波时间差实时获得积水深度信息,进而利用域控制器对积水深度信息进行处理,然后向底盘升降装置发送升降信号,自动控制底盘的升降,无需驾驶员手动操作,减少了驾驶员的工作量,确保了驾驶员的行车安全。
