Problems solved by technology

[0005] Due to the existence of redundant equipment, when a main equipment fails, the failure itself may not affect the automatic driving function, but the existing technology will still issue an alarm, which will undoubtedly increase the maintenance cost of unmanned equipment. It also reduces the efficiency of the use of unmanned equipment

Embodiment Construction

[0039] At present, the perception results that the automatic driving function of an unmanned device relies on are mainly the comprehensive perception results obtained through all the sensors and corresponding software of the unmanned device itself. For example, independent hardware such as lidar, millimeter-wave radar, inertial measurement unit, and camera on unmanned equipment first output their own single perception results, and then summarize and synthesize each single perception result through software to obtain the final synthesis Perception results, based on the obtained comprehensive perception results, automatic driving functions such as trajectory planning are realized.

[0040] However, for a single piece of hardware or software, when it fails or its performance decreases, will it reduce the accuracy of the comprehensive perception results? impact, which is difficult to quantify. This leads to the fact that in the prior art, only a single hardware and software can b...

Abstract

This specification discloses a fault detection method, device, storage medium, and electronic equipment. The embodiment of this specification no longer detects each hardware or software on the unmanned equipment separately, but obtains the current status of multiple unmanned equipment. Synthesize the sensing results, and determine the first difference between the current comprehensive sensing results of each unmanned device and the current comprehensive sensing results of other unmanned devices, and detect whether the unmanned device is faulty according to the first difference. Since the comprehensive perception result is not the result of a single hardware or software output, but the final perception result of all hardware and software, the above method can detect the unmanned device as a whole based on the final perception result of the unmanned device Whether there is a failure that will affect the automatic driving function can reduce the maintenance cost of unmanned equipment and improve the efficiency of unmanned equipment.

Description

technical field [0001] This specification relates to the technical field of automatic driving, and in particular to a fault detection method, device, storage medium and electronic equipment. Background technique [0002] At present, a lot of hardware is usually arranged on the unmanned equipment that can realize the automatic driving function, and the corresponding software is supplemented to realize the perception function of the unmanned equipment. For example, by arranging lidar, millimeter-wave radar, inertial measurement unit, camera and other hardware on unmanned equipment, supplemented by corresponding machine learning models, unmanned equipment can realize its perception of its surrounding environment. How to detect the faults of these hardware and software has become an urgent problem to be solved. [0003] In the prior art, when fault detection is performed on various hardware and software on the unmanned equipment, each hardware and each software is usually detec...
