Embodiment Construction
[0051] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0052] The solutions of the embodiments of the present invention are mainly: after detecting that an accident occurs in the autonomous vehicle, start a fault self-checking and analysis function; The fault self-test is carried out at the layer and the self-test result is generated; the corresponding accident description information is determined according to the self-test result, and the accident description information is fed back, which can improve the accuracy of sensor fault detection and avoid misjudgment. It leads to irreparable losses, ensures the safety of automatic driving, reduces the possibility of vehicle loss of control, avoids the waste of resources during fault analysis of automatic driving vehicles, reduces the cost of fault analysis and the accident rate of automatic driving, and improves automati...

The invention discloses an automatic driving vehicle accident fault self-checking method, device and equipment and a storage medium, and the method comprises the steps: starting a fault self-checking analysis function after an accident of an automatic driving vehicle is detected; according to the self-checking analysis function, fault self-checking is carried out on a sensing layer, a decision-making layer and an execution layer of the automatic driving vehicle in sequence, and a self-checking result is generated; the corresponding accident description information is determined according to the self-inspection result, and the accident description information is fed back, so that the accuracy of sensor fault detection can be improved, irreparable loss caused by misjudgment is avoided, the safety of automatic driving is ensured, the possibility that the vehicle is out of control is reduced, and the safety of the vehicle is improved. Resource waste of the automatic driving vehicle during fault analysis is avoided, the fault analysis cost and the automatic driving accident rate are reduced, and the automatic driving vehicle accident fault self-inspection speed and efficiency are improved.
Description
technical field [0001] The present invention relates to the technical field of automatic driving, and in particular, to a method, device, equipment and storage medium for self-checking an accident and fault of an automatic driving vehicle. Background technique [0002] Nowadays, accidents of vehicles equipped with automatic driving assistance systems are frequent. In order to learn from them, improve vehicles and meet the safety of road vehicles; for example, when an automatic driving vehicle is involved in an accident, the self-accident vehicle can complete the fault self-detection, and It is especially important to report the cause of the accident into a proprietary database of road traffic accidents. [0003] The existing scheme is that if the vehicle does not exit the automatic driving state, it is detected whether the map data exists when the vehicle fails, and if there is map data, the failure of the vehicle is classified to obtain the failure category of the vehicle; ...
