In detail, the running position of the vehicle currently running, the running vehicle speed, and the destination of the vehicle are acquired, thereby obtaining the running condition of the vehicle. Wherein the data can be obtained through device detection or manual uploading. In detail, the driving position and the driving speed can be obtained in real time, and can be uploaded for a plurality of times at the same time. Wherein the destination can be uploaded after input by the navigation device. Multiple paths to the destination through the current initial travel position of the vehicle may be obtained by the navigation device. The method comprises the steps of dividing a path into a plurality of road sections, monitoring the traffic flow of different road sections, and estimating the traffic flow of the next road section in sequence according to the traffic flow of the previous road section. The preset speeds are respectively set by utilizing the traffic flow of different road sections, so that whether the vehicle is overspeed or not is judged according to the preset speeds, and the vehicle which is freely driven is regulated to a constant speed state when overspeed occurs, so that traffic danger caused by acceleration of a driver in the driving process is prevented.

Alternatively, the mobile terminal or the service terminal may calculate the speed of the traveling vehicle according to the speed and the traveling position of the traveling vehicle, thereby obtaining the traveling speed of the vehicle.
In some embodiments of the present application, the above-described running vehicle speed of the vehicle is detected by a vehicle speed sensor, and is uploaded to a server through a wireless network.

When the driving position reaches the next road section, the driving speed is uploaded by the vehicle speed sensor once, so that whether the driving speed of the vehicle exceeds the overspeed is judged through the service end. The server can analyze the running condition and road condition of the vehicle through the processor to obtain a vehicle speed judging result, and the vehicle control system is controlled to switch different driving modes through a signal sent out by the vehicle speed judging result.

In detail, by uploading the traffic flow to the server, the vehicle density of each road section can be estimated according to the traffic flow, so that the vehicle speed is controlled to achieve the effect of maintaining traffic safety.
In some embodiments of the present application, a plurality of vehicle speeds of different road segments are detected according to a plurality of speed measuring devices, and an average speed of each vehicle is calculated, when a next road segment of a current road segment in a road traveling direction is a plurality of road segments, a traveling distance of the vehicle in a next period is calculated according to the average speed of each vehicle, and the vehicle flow of different road segments is obtained according to the traveling distance of each vehicle.

In detail, when the road section of the current path in the road traveling direction is connected with the road sections of other paths, the next road section of the current road section is a plurality of road sections, the traffic flow of each road section is calculated according to the previous road section, and the preset speed for limiting the speed is obtained according to the traffic flow and the connected path quantity. Wherein the more paths, the larger the preset vehicle speed, and the less paths, the smaller the preset vehicle speed. Alternatively, the number of paths is 10km/h for two time preset vehicle speeds and 20km/h for three time preset vehicle speeds.
In some embodiments of the present application, whether the preset flow is exceeded is determined according to the vehicle flow, and when the preset flow is exceeded, whether the running vehicle speed exceeds the preset speed is determined.
In detail, whether the vehicle exceeds a preset value or not is judged according to the vehicle flow, when the vehicle does not exceed the preset value, the vehicle is in a free driving mode, and when the vehicle exceeds the preset speed, whether the running vehicle speed exceeds the preset speed is judged, so that whether the deceleration auxiliary driving is carried out or not is judged. The constant-speed driving mode is to keep the current speed of the vehicle, the deceleration driving mode is to uniformly decelerate the vehicle from the current speed to the preset speed, and the vehicle can be switched back to the free driving mode after a certain time. Alternatively, when the vehicle enters the next road section, it is again determined whether the vehicle speed is overspeed, so that the running mode of the vehicle is switched according to the determination result. When the traffic flow is large, the preset speed is utilized to limit the speed, and when the traffic flow is small, the vehicle can conveniently pass through the road section quickly through a free driving mode.
