Abstract

The invention proposes a vehicle fault inquiry system which comprises multiple node controllers, a display module and a fault inquiry controller. The multiple node controllers are respectively corresponding to multiple control sub-systems of a vehicle and are used for generating diagnostic messages and transmitting the diagnostic messages through CAN buses. The display module which is used for displaying an inquiry menu aiming at the multiple node controllers, receiving inquiry commands aiming at the inquiry menu, and generating inquiry messages according to the inquiry commands and transmitting the inquiry messages through a CAN bus. The fault inquiry controller is used for receiving the diagnostic messages and the inquiry messages, acquiring corresponding diagnostic messages according to the inquiry messages, and transmitting fault information in the corresponding diagnostic messages to the display module for displaying. The system can perform automatic diagnosis in advance, can perform early and real-time diagnosis, and at the same time can prevent faulty operation caused by misjudgment of faults during a maintenance process. A vehicle fault inquiry controller and a vehicle are also provided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle fault query system, a vehicle fault query controller and a vehicle. Background technique [0002] At present, when performing fault diagnosis on vehicles, the internationally popular diagnostic methods are mainly implemented based on diagnostic commands, mainly referring to ISO14229, ISO14230, etc., and diagnostic equipment such as OBD (On-Board Diagnostics, on-board diagnostic system) can also be used for reference.
