Embodiment approach

[0130] As a possible implementation manner, the vehicle diagnostic device further includes:

[0131] A setting unit 607, configured to set a first display area and a second display area at the ECU node of the vehicle network topology map. Wherein the first display area is used to display ECU node information; the second display area is used to display ECU node fault code information.

[0132] In order to facilitate the user's diagnostic operation, the setting unit 607 sets up two display areas at the nodes of the vehicle network topology map, and distinguishes them with different color marks, for example, the first display area is marked in green to display the node information of the ECU ; The second display area is marked in red to display the fault code information of the ECU node, such as the number of fault codes. Of course, the description of the colors here is just for example, and this embodiment is not limited to these two colors, and other colors can also be used. ...

Abstract

The invention discloses a vehicle diagnosis method and a vehicle diagnosis device. The vehicle diagnosis method includes establishing the communication connection with a vehicle electronic control unit ECT; receiving the user's diagnosis command; transmitting the vehicle type reading command; determining the vehicle type information according to the information of the vehicle in response to the vehicle type reading command; drawing the whole vehicle network topological diagram of the vehicle; and performing a corresponding diagnosis operation based on the user's selection of the topological diagram ECT nodes. The vehicle diagnosis method and the vehicle diagnosis device can automatically identify the vehicle type, simplify the diagnosis operation, prevent the problem that the vehicle cannot be diagnosed due to the wrong selection of the vehicle type, and meanwhile, the diagnosis operation is simple.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle diagnosis method and vehicle diagnosis equipment. Background technique [0002] With the development of vehicle technology, the electronic control system ECU of existing vehicles is becoming more and more complex. Vehicle failure analysis increasingly relies on professional vehicle diagnostic equipment. At the same time, in order to meet the differentiated needs of different customers, vehicle manufacturers are producing more and more types of vehicles. Even the same vehicle manufacturer has hundreds of models. The current vehicle diagnostic equipment first lists all the vehicle models of the vehicle manufacturer. When the user performs vehicle diagnosis, he needs to select the corresponding vehicle model before proceeding with the diagnosis. However, it is not easy to accurately distinguish various models for the current huge number of various vehicles with small d...
