The invention discloses a method, a device, a vehicle and a storage medium for detecting a loose interface. The method includes: configuring a udev rule file, and the device manager udev passes the udev rule file and generates a device file and a symbolic link matching device attributes; through the symbolic link Access the corresponding device file; determine whether the device file corresponding to the symbolic link has changed; if there is a change, confirm that the interface corresponding to the symbolic link is loose. Through the embodiment of the present invention, the change of the corresponding relationship between the symbolic link and the device file is detected to determine that the interface is loose, the problem of the loose interface can be found in time, and the user is reminded to maintain the loose interface, thereby improving the reliability of the unmanned driving system. maintainability.
Description
technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a method, a device, a vehicle and a storage medium for detecting loose interfaces. Background technique [0002] At present, the host system on the driverless car is generally a linux system. The driverless system configures a device mapping rule for the corresponding USB or serial device through the configuration rules of udev. The application can still access the symbolic link configured in the configuration rule when the file handle allocated by the operating system to the serial device changes. for proper access. The change of the file handle allocated by the operating system to the serial device is often caused by the looseness of the device interface, and the looseness of the interface needs to be prevented and maintained in advance. If the looseness of the device interface cannot be detected and maintained in time, the device may be disconnected and cannot ...
