Embodiment 1

[0030] figure 1 It is a flow chart of the abnormality detection method of the self-driving vehicle provided by Embodiment 1 of the present invention. This embodiment can be applied to detect whether there is an abnormality in the safety system of the self-driving vehicle. This method can be implemented by the abnormality detection device of the self-driving vehicle Execution, the device can be implemented by software and / or hardware, and generally can be integrated into computer equipment. Such as figure 1 As shown, the method specifically includes:

[0031] S110, acquiring the health information of the safety detection module of the vehicle.

[0032] Among them, self-driving vehicles are generally equipped with safety systems, which are used to check the abnormal conditions of various systems of the vehicle and the dangerous situations encountered by the vehicle at any time. For different inspection purposes, the safety system includes multiple safety detection modules (or...

Embodiment 2

[0061] On the basis of the above-mentioned embodiments, this embodiment provides an implementation manner of anomaly detection of a policy mechanism. The strategy mechanism sends strategy mechanism detection information to the vehicle control center at an interval set time, wherein the strategy mechanism detection information includes: strategy time and strategy count, and the strategy mechanism detection information is used to instruct the vehicle control center to follow the policy The agency detection information and the strategic agency comparison information determine whether there is an abnormality in the strategic agency.

[0062] Among them, the setting time refers to the time interval for the policy agency to give the policy. In fact, the time interval for the policy agency to give the policy is determined by the detection time interval of the security detection module, because the security detection module will report to the policy agency every time it detects , and ...

Embodiment 3

[0068] figure 2 It is a schematic structural diagram of an abnormality detection device for an automatic driving vehicle provided in Embodiment 3 of the present invention, as shown in figure 2 As shown, the device includes:

[0069] The health information acquisition module 210 is used to acquire the health information of the safety detection module of the vehicle;

[0070] A comparison information acquisition module 220, configured to acquire the comparison information of the safety detection module;

[0071] An information comparison module 230, configured to compare the health information with the comparison information;

[0072] The abnormality judging module 240 is configured to judge whether there is an abnormality in the safety detection module according to the comparison result.

[0073] Optionally, the device further includes: an information recording module, configured to record the detection count value of the safety detection module according to preset rules. ...

Abstract

The embodiments of the invention disclose an abnormal detection method and device of an autonomous vehicle, a system, equipment and a medium. The abnormal detection method includes the steps that health information of a safety detection module of the vehicle is obtained; comparison information of the safety detection module is obtained; the health information is compared with the comparison information; and according to comparative results, whether the safety detection module is abnormal or not is judged. According to the embodiments, through the health information of the safety detection module and the comparison information of a module abnormal detection mechanism for the safety detection module, whether the safety detection module is abnormal or not is judged, abnormal detection of thesafety detection module is realized, the abnormality can be found in time, thus the robustness of an unmanned system is higher, and the safety is more guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to automatic driving technology, and in particular to an abnormality detection method, device, system, equipment and medium for an automatic driving vehicle. Background technique [0002] At present, in self-driving vehicles, it is generally equipped with a safety redundant hot-standby system (referred to as a safety system). The detection function item for abnormal conditions is defined as a security detection item checker, referred to as checker for short. The checker will report the inspection results to the policy agency to formulate the next step strategy when encountering these abnormal situations. Therefore, when the unmanned driving system encounters some problems such as system failure, the safety system can take over the vehicle in time to ensure driving safety. [0003] However, if each checker of the safety system is abnormal, the information provided by it will be outdated or invalid, and there...
