specific Embodiment approach 1

[0051] An abnormality management system for an automatic driving vehicle in this embodiment, such as figure 1 As shown, the management system includes an abnormality detection module 1, which is used to statistically collect fault information generated by each subsystem in the automatic driving system, and store it in a csv file in the form of a list; wherein, the fault information generated by each subsystem The information is generated through the same set of fault coding rules; among them, each subsystem in the automatic driving system includes the perception subsystem, the positioning subsystem, the decision-making subsystem, the control subsystem, and the communication subsystem;

[0052] The fault triggering module 2 is used to centrally judge all the fault information collected by the abnormal detection module 1, obtain the fault level of the fault information, and send it to the fault processing module; wherein, the fault levels are sorted from high to low as : normal,...

specific Embodiment approach 2

[0064] In the abnormality management system of an automatic driving vehicle according to this embodiment, the fault processing module 3 further includes a manual intervention interface for resetting or bypassing the fault when the vehicle triggers a fault so that it will not be triggered again.

specific Embodiment approach 3

[0066] In the anomaly management system of an automatic driving vehicle according to this embodiment, the fault coding rule of the fault information generated by the abnormal detection module 1 is as follows: the internal fault levels of each subsystem in the automatic driving system include hardware level faults and algorithm levels Fault; Among them, hardware-level faults are screened by detecting the working status of sensors and data content (data content detected by sensors), and judged by fusing multiple sensors; algorithm-level faults are judged by the internal logic of the system. When the system runs abnormally , output it in the form of fault code;

[0067] The fault code records four fault attributes: fault level, occurrence module, fault classification, and fault serial number; fault levels are divided into normal, warning, general fault, and serious fault, which correspond to INFO, WARN, ERROR, and FATAL respectively, and are represented by the initials Coding; th...

Abstract

The invention provides an abnormality management system of an autonomous vehicle and an abnormality handling method of the autonomous vehicle and belongs to the field of automatic driving. By the adoption of an existing automatic driving technology, the abnormality handling capacity is poor. An abnormality detecting module conducts statistics and collection of fault information generated by each subsystem in an automatic driving system and stores the fault information; a fault triggering module conducts concentrated judgment on the fault information collected by the abnormality detecting module, obtains fault grades of the fault information and sends the fault grades to the fault processing module; the fault processing module sorts the received fault grade information according to the fault grades from low to high and then processes the faults according to the fault grades from high to low, and whether the current fault is bypassed or not is judged; a data management module backups data after fault is triggered when abnormality happens. The abnormality management system of the autonomous vehicle and the abnormality handling method of the autonomous vehicle can rapidly find surrounding abnormal conditions and rapidly handle the abnormal conditions.

Description

technical field [0001] The invention relates to the management of automatic driving of vehicles, in particular to a management system and processing method for abnormal situations of automatic driving vehicles. Background technique [0002] Due to the advantages of saving labor costs, reducing accident rate, and reducing fuel consumption, all walks of life are currently working hard to promote the development of autonomous driving. With the development of various on-board sensor technologies and artificial intelligence technologies, autonomous driving technology is also increasingly commercialized. Especially in closed and semi-closed application scenarios, such as automated docks, airports, closed parks, etc., autonomous driving technology is expected to be the first to be commercially implemented, but at the same time it is also facing many problems. The stability of the product is the key to whether autonomous driving can be widely used in various industries; and how the...
