Abstract

The embodiment of the application provides a vehicle diagnosis session maintaining method, device, equipment, storage medium and vehicle. The method comprises the steps that a diagnosis device establishes a diagnosis session between a gateway device and a module to be diagnosed, the diagnosis device periodically sends a first diagnosis service request to the module to be diagnosed through the diagnosis session, the gateway device determines the interval duration between the moment when the diagnosis device receives the first diagnosis service request sent last time and the current moment when the target communication connection between the diagnosis device and the gateway device is not disconnected, and when the interval duration is greater than or equal to a target duration threshold, the gateway device autonomously sends a second diagnosis service request to the module to be diagnosed, so that the module to be diagnosed responds to the second diagnosis service request to maintain the diagnosis session. The application can maintain the diagnosis session when the network connection is unstable.

Description

Vehicle diagnosis session maintaining method, device, equipment, storage medium and vehicle Technical Field The present application relates to the field of vehicle technologies, and in particular, to a method, an apparatus, a device, a storage medium, and a vehicle for maintaining a vehicle diagnosis session. Background In the electronic systems of vehicles, on-board diagnostics have become a central tool for vehicle maintenance, software upgrades and troubleshooting. With the development of on-board network technology, on-board diagnostics may be implemented in dependence on wireless diagnostic technology (e.g., wi-Fi). For example, a technician may establish a wireless connection with the vehicle through a Wi-Fi module-mounted diagnostic device (e.g., a handheld device or tablet) and send a diagnostic request to the vehicle electronic control unit (Electronic Control Unit, ECU) through a unified diagnostic service (Unified Diagnostic Services, UDS) to maintain a diagnostic session. However, wi-Fi networks have the natural characteristics of signal fluctuations. In the scenario of unstable Wi-Fi signals (the connection itself is not disconnected), the diagnosis service signals cannot reach the ECU in time, and further the ECU misjudges that the diagnosis session is interrupted, so that the vehicle-mounted diagnosis is interrupted. Disclosure of Invention The embodiment of the application provides a vehicle diagnosis session maintaining method, device, equipment, storage medium and vehicle, which are used for maintaining a diagnosis session when network connection is unstable. In a first aspect, an embodiment of the present application provides a vehicle diagnostic session maintenance method, the method including: the diagnosis equipment establishes a diagnosis session between the gateway device and the module to be diagnosed; the diagnosis equipment periodically sends a first diagnosis service request to the module to be diagnosed through the diagnosis session; The gateway device determines the interval duration between the time when the first diagnosis service request is last sent by the diagnosis device and the current time when the target communication connection between the diagnosis device and the gateway device is not disconnected; And when the interval time length is greater than or equal to a target time length threshold, the gateway device autonomously transmits a second diagnosis service request to the module to be diagnosed so that the module to be diagnosed responds to the second diagnosis service request to maintain the diagnosis session. Optionally, before the determining that the interval duration between the time when the diagnostic device last sent the first diagnostic service request and the current time is received, the method further includes: Periodically sending the interval duration of the first diagnosis service request by the diagnosis equipment as the target duration threshold; Or alternatively And dynamically determining the target duration threshold based on the network signal dynamic parameters of the target communication connection. Optionally, the method further comprises: and stopping sending the second diagnosis service request to the module to be diagnosed when the target communication connection is detected to be disconnected.
