The above and other objects, features and advantages of the present application will become more apparent through a more detailed description of the embodiment of the present application in conjunction with the accompanying drawings. The accompanying drawings are used to provide a further understanding of the embodiment of the present application, and constitute a part of the specification, and are used together with the embodiment of the present application to explain the present application, and do not constitute limitations to the present application.

Apparently, the described embodiment are only some of the embodiment of the present application, rather than all the embodiment of the present application. It should be understood that the present application is not limited by the exemplary embodiment described here.
This application can be applied to any technical field using automatic driving or assisted driving. For example, the embodiment of the present application can be applied to vehicles with automatic driving or assisted driving functions. During the driving process of the vehicle, there may be unexpected events such as the sudden change of the driving lane of the own vehicle or the sudden change of driving lanes of other vehicles. lead to traffic accidents, and the automatic driving or assisted driving functions are used to avoid similar traffic accidents or minimize the severity of accidents when they occur. However, the realization of automatic driving or assisted driving functions needs to be based on the planning of the vehicle's driving path, that is, the realization of automatic driving or assisted driving functions is based on determining the driving path of the vehicle, so as to determine whether the own vehicle is safe on the future driving path. hidden dangers (that is, whether there is a possibility of traffic accidents), and then take corresponding measures according to the occurrence status and probability of the safety hazards, such as forward collision warning, adaptive cruise control, automatic emergency braking, etc.
Usually, the realization of automatic driving or assisted driving is to plan a fixed driving route based on the map. For example, based on the high-definition map provided by the third party, the driving route is planned before driving, and the vehicle travels according to the driving route. However, since the high-definition maps provided by third parties are usually static maps, that is to say, the high-definition maps will not change in a short period of time. It will not be displayed, which will obviously lead to the fact that the driving path of automatic driving or assisted driving may not be optimal, or even unrealizable (for example, temporary road closures, etc. make the planned driving path impassable). Moreover, when driving on a planned driving route, the vehicle's own perception system is usually used to obtain the surrounding road condition information and proceed. In order to ensure the safety of the driving process, it is necessary to install sensors, radars and or cameras and other sensing devices, but even so, the vehicle still has a certain viewing angle, that is, there are certain safety hazards, and these sensing devices will inevitably lead to an increase in the cost of the vehicle, and multiple sensing devices are multiple failure points, namely There is a greater risk of failure of the vehicle.
