After the collected vehicle yaw rate value is compared with the vehicle yaw rate value threshold value, if the vehicle yaw rate value is greater than the vehicle yaw rate value threshold value Then continue to execute the judgment. Comparing the value of the vehicle yaw rate response time with the vehicle yaw rate response time threshold, when the vehicle yaw rate response time is greater than the vehicle yaw rate response time threshold, output a dynamic flag, which can be 1, 1 means that the dynamic marking of the current driving section is activated, and the information of the dynamic marking of Xinhua Road as activated is uploaded to the cloud platform. The cloud platform collects the dynamic markings of Xinhua Road uploaded by different vehicles. When the dynamic marking is activated, the record If the ratio of the number (50) to the sum of the records that are dynamically marked as active (50) and the number of records that are dynamically marked as inactive (25) is greater than 50% of the threshold, then it is determined that Xinhua Road is a dynamic road section.

Switch the driving mode in the driving mode pushed by the cloud platform. On this road section, switch the current driving mode to the sports mode to ensure driving safety; if the all-terrain system switch is triggered at this time, it means that the driver has not Switching the driving mode of the vehicle through the all-terrain system switch, the driver may not know that the Xinhua Road in front is a sharp curve section, and actively executes the switching of the driving mode through the all-terrain system switch through his own judgment. The mode is switched to sports mode to ensure driving safety. By judging whether the road is a dynamic road section, when the vehicle travels to this area, it will remind the driver to ensure the safety of the driving process.
