The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
In road traffic, there are many factors that affect the traveling of vehicle-mounted devices. For example, when the weather changes, the driving speed of the vehicle-mounted device is reduced due to the bad weather. For example, road surface obstacles, road surface maintenance, scratches and the like can cause lane occupation, and further influence the driving of the vehicle-mounted equipment.
