Abstract

The invention provides a system monitoring method and device. The method comprises the following steps that state information of a to-be-monitored system obtained; when the state information satisfiesa triggering condition, a to-be-adjusted subsystem in the to-be-monitored system and a target acquisition frequency of the to-be-adjusted subsystem are determined; an initial acquisition frequency ofthe to-be-adjusted subsystem is adjusted to be a target acquisition frequency, the state information of the to-be-adjusted subsystem is acquired according to the target acquisition frequency, for example, when the fault occurs, the acquisition frequency is increased; and if the subsystem runs normally, the acquisition frequency is reduced. Due to the fact that the probability of failure is relatively small, the storage space occupied by the collected state information can be effectively reduced, and the collection efficiency in the case of faults and the like is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a system monitoring method and device. Background technique [0002] The current Advanced Driver Assistance System (Advanced Driver Assistance System, ADAS) uses various sensors installed on the car, such as cameras and radars, to collect environmental data inside and outside the car at the first time, and perform static and dynamic analysis. The technical processing of object identification, detection and tracking, so that the driver can detect possible dangers in the fastest time, so as to attract attention and improve the active safety technology of safety. Therefore, remote monitoring of the functional status of the ADAS system has become an essential requirement. At present, data acquisition equipment can only collect the status information of the ADAS system at a single frequency, which wastes a lot of storage space and reduces the collection efficiency. In addition, when...
