In the concrete implementation, taking the preset rainfall threshold value as 17.36 microns/minute as an example, if the rainfall intensity is greater than or equal to 17.36 microns/minute, judging that the current rainfall is heavy rain or above, the water accumulation speed of low-lying road sections such as underground passages and tunnels is extremely high, and judging that the current vehicle has the water soaking risk in the water accumulation-prone road sections; if the rainfall intensity is less than 17.36 microns/minute, the current rainfall is judged to be below heavy rain, the water accumulation speed of low-lying road sections such as underground passages and tunnels is general, and at the moment, the current vehicle is judged to have no water soaking risk in the road sections with easy water accumulation. According to the scheme, the current rainfall intensity is determined according to the rainfall intensity information, the current rainfall intensity is compared with a preset rainfall threshold value, and a comparison result is generated; when the comparison result is that the current rainfall intensity is greater than or equal to the preset rainfall threshold, judging that the current vehicle has a water soaking risk in a section where water is easy to accumulate; the comparison result does current rainfall intensity is less than when predetermineeing the rainfall threshold value, judge that current vehicle does not have the bubble water risk in easy ponding highway section, whether the current vehicle of aassessment that can be detailed accurate has the bubble water risk, and then can be in the great rainy day of rainfall, automatic for the car owner replans and avoids easy ponding highway section, has avoided the vehicle to bubble water or has broken down.

And step S223, when the judgment result shows that the water soaking risk does not exist, the current planned path is not adjusted, and the current planned path is displayed.
It should be understood that, when the determination result is that there is no risk of water bubbles, that is, when there is no water bubbles or no anchor in the current vehicle, the current planned path may be directly used as the final target planned path without adjusting the current planned path.
