Embodiment approach

[0144] In this embodiment, the second terminal can screen a plurality of first risk values ​​based on vehicle body stability parameters, and select a reference risk threshold value for a relatively stable vehicle body during braking, which can improve the safety of passengers riding on the target vehicle. comfort.

[0145] In a possible implementation manner, the reference risk threshold is a reference braking moment, and the second terminal based on the motion information of the target vehicle in the virtual test scene, the motion information of the collision target in the virtual test scene, and the braking The dynamic performance parameter determines the initial braking moment of the target vehicle. When the target vehicle brakes with the maximum braking capacity at the initial braking moment, the target vehicle just does not collide with the collision target. The second terminal determines the reference braking moment of the target vehicle in the virtual test scene based o...

example 1

[0161] Example 1. In a possible implementation, the second terminal sends a test parameter acquisition request to the first terminal, the test parameter acquisition request is used to acquire the test parameters of the target vehicle, and the first terminal is the vehicle-mounted terminal of the target vehicle . In response to receiving the test parameter acquisition request, the first terminal sends the first test parameter of the target vehicle to the second terminal.

[0162] Example 2. The second terminal sends a test parameter acquisition request to the server, the test parameter acquisition request is used to acquire the braking test parameters of the target vehicle, and the test parameter acquisition request carries the identification of the target vehicle. In response to receiving the test parameter acquisition request, the server performs an inquiry based on the target vehicle identifier to obtain the first test parameter of the target vehicle. The server sends the f...

Abstract

The invention discloses a risk threshold determination method and device, equipment and a storage medium, and belongs to the technical field of computers. According to the technical scheme provided by the embodiment of the invention, in the process of determining the risk threshold value, the real braking performance parameters of the target vehicle are obtained. The reference risk threshold value is determined based on the braking performance parameter and the scene parameter of the virtual test scene, and the braking performance parameter and the virtual scene parameter are standard parameters in an ideal state, so that the determined reference risk threshold value is a theoretical risk value. According to the method, testing is carried out in a standard test scene based on the reference risk threshold value, a first test parameter is obtained, the standard test scene is a scene built based on the test standard, and then the obtained first test parameter can indicate whether the target vehicle can pass the test corresponding to the standard or not based on the reference risk threshold value. The reference risk threshold value is adjusted according to the first test parameter, so that the accuracy of the risk threshold value can be improved, and the safety of the vehicle is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, device and storage medium for determining a risk threshold. Background technique [0002] With the development of computer technology, automatic driving technology has been developed rapidly and widely used. In autonomous driving technology, vehicle safety is the area that deserves the most attention. [0003] In related technologies, various vehicle active safety technologies are used to improve the safety of vehicles during automatic driving. The active emergency braking system is an active safety technology. The active emergency braking system determines the collision risk value between the vehicle and the target in front through various sensors on the vehicle. The collision risk value determined in real time and the preset The risk value threshold is used to determine whether to perform automatic braking. The determination of the risk valu...
