Problems solved by technology
[0002] With the promotion and use of unmanned driving technology, unmanned vehicles have been gradually promoted and applied. However, in the current operation of unmanned vehicles, the road surface status has a great impact on the safety and reliability of vehicle operation. When the vehicle speed When the matching between the vehicle running state and the road surface state such as the turning radius and turning radius is poor, on the one hand, it will easily lead to relatively poor running comfort of the vehicle, and on the other hand, it will also easily lead to safety accidents during vehicle running. To solve this problem, there is currently a lack of a A road condition evaluation method that can match the whole road condition with the vehicle operation along with the vehicle operation, resulting in a large safety hazard when the autonomous vehicle is running. Therefore, in view of this situation, it is urgent to develop an unmanned vehicle. State evaluation method to meet the needs of practical use
