Vehicle fault remote diagnosis method and system and storage medium

The invention provides a vehicle fault remote diagnosis method and system and a storage medium, and the method comprises the steps: determining a fault source of a vehicle end based on a fault detection signal of the vehicle end, determining a remote diagnosis command corresponding to the fault source, and transmitting the remote diagnosis command to the vehicle end; receiving fault detection data generated when the vehicle end executes the remote diagnosis command; and determining a fault maintenance scheme corresponding to the fault detection data and a maintenance end corresponding to the fault source, and sending the fault maintenance scheme to the maintenance end. The cloud can monitor software faults and hardware faults in the running process of the vehicle in real time, and when the faults occur, fault information can be reported to the cloud immediately. And for hardware faults and software faults, appointment maintenance or remote upgrade repair can be performed, so that the manual participation degr
