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

Embodiment Construction

[0028] Such as figure 1 , 2 As shown in and 3, a method for evaluating the ground state of an autonomous vehicle includes the following steps:

[0029] The first step is to build the vehicle’s own positioning hardware equipment. First, according to the needs of use, a number of road surface detection devices 1 are installed on the outer surface of the vehicle chassis. A wireless data communication device 2, a detection data processing device 3 and a GNSS satellite navigation device 4 are installed in the vehicle, and then the detection data processing device 3 is respectively equipped with a wireless data communication device 2, a GNSS satellite navigation device 4, a road surface detection device 1 and a vehicle driving computer circuit. Electrical connections;

[0030] The second step is to construct the evaluation calculation function. After the first step is completed, the road surface movement resistance calculation function and the wheel slip rate calculation function ...

Abstract

The invention relates to a method for evaluating a ground state of an autonomous vehicle. The method comprises the steps of constructing vehicle self positioning hardware equipment, constructing an evaluation calculation function, performing road surface data acquisition, performing vehicle operation data testing, performing state evaluation and performing data feedback. According to the method ofthe invention, simple and easy-operating control operation, high data testing result, high data testing precision and high data processing capability are realized on one hand; and on the other hand,acquisition and operation can be effectively performed on the vehicle self operation state and the actual road surface state in a full vehicle operation process, thereby efficiently and conveniently acquiring the current road surface state parameter information in operation of the vehicle; and furthermore the calculated road surface state parameter information can be fed back to the control systemof the autonomous vehicle for guiding and adjusting parameters such as vehicle operation speed, thereby greatly improving safety and reliability in operation of the vehicle.
