Abstract

The invention is suitable for the technical field of computers, and provides a vehicle diagnosis method and device, electronic equipment and a storage medium. The method comprises the steps of: obtaining an ECU selection instruction when a first communication link is in a connection state, and determining a target ECU; obtaining a function selection instruction, and determining a target function for the target ECU according to the function selection instruction; if the target function is a special function, destroying the first communication link; and calling a target dynamic link library corresponding to the special function, and transmitting the information of the target ECU and a target communication parameter to the target dynamic link library, so as to enable the target dynamic link library to create a second communication link according to the target communication parameter, and when the second communication link is in a connection state, executing the target function of the target ECU according to the information of the target ECU. According to the embodiment of the invention, vehicle diagnosis can be realized flexibly and conveniently.

Description

technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a vehicle diagnosis method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of automotive electronics, electronic control units (ECUs) are widely used in modern vehicles. While ECU improves vehicle economy, comfort and safety, it also makes the electronic and electrical systems in vehicles more and more complex, which also promotes greater development of automotive diagnostic technology. At present, the domestic mainstream vehicle diagnosis development method is that the development technicians use the code writing method to carry out function development according to the agreement provided by the manufacturer. This development method makes the subsequent vehicle diagnosis function only rely on the fixed developed code, resulting in the failure of vehicle diagnosis. Less flexibility. Content...
