Vehicle diagnosis method, server and diagnosis device

A vehicle diagnosis method applied to a diagnosis device, comprising:

• establishing a connection with a vehicle to be diagnosed and acquiring vehicle information;
• generating a request for acquiring diagnosis software based on a user instruction, wherein the request comprises the vehicle information and user information;
• sending the request for acquiring the diagnosis software to a server to cause the server to determine a corresponding diagnosis software function module list based on the vehicle information;
• receiving the diagnosis software function module list and presenting the diagnosis software function module list to the user, to determine a target diagnosis function module;
• sending information of the target diagnosis function module determined by the user selecting from the diagnosis software function module list to the server to cause the server to determine whether the user has an authorization qualification on the target diagnosis function module based on the user information and perform a corresponding operation for acquiring the target diagnosis function module based on a determining result;
• and
• receiving an operation result fed back by the server and diagnosing the vehicle to be diagnosed based on the acquired target diagnosis function module.

A server, comprising:

• a memory configured to store an executable computer program;
• a processor configured to call the executable computer program to:
• acquire a request for acquiring diagnosis software sent by a diagnosis device based on a vehicle to be diagnosed, wherein the request comprises user information and vehicle information of the vehicle to be diagnosed;
• determine a corresponding diagnosis software function module list based on the vehicle information;
• send the diagnosis software function module list to the diagnosis device, so that the diagnosis device presents the diagnosis software function module list to a user, to determine a target diagnosis function module;
• receive from the diagnosis device information of the target diagnosis function module determined by the user selecting from the diagnosis software function module list;
• determine whether the user has an authorization qualification on the target diagnosis function module based on the user information to obtain a determining result;
• and
• perform a corresponding operation for acquiring the target diagnosis function module based on the determining result and feedback the target diagnosis function module to the diagnosis device, so that the diagnosis device diagnoses the vehicle to be diagnosed based on the acquired target diagnosis function module.
