Vehicle fault diagnosis and data analysis system and vehicle

Abstract

The invention relates to a vehicle fault diagnosis and data analysis system and a vehicle. The system comprises a monitoring host and a fault diagnosis module disposed on a vehicle, wherein the monitoring host is provided with a communication interface for communication connection with a monitoring platform; the monitoring host is used for sampling connection with the whole vehicle CAN network toobtain vehicle state information; the fault diagnosis module is in communication connection with the monitoring host for acquiring the vehicle state information, performing fault diagnosis on the vehicle state information to acquire a corresponding fault type and sending the acquired vehicle state information and the corresponding fault type to the monitoring platform. Through arranging the faultdiagnosis module at the vehicle-mounted monitoring host side, the fault of a power battery can be diagnosed automatically according to the vehicle state information, a diagnosis result is obtained, and as the fault diagnosis result is completed at the vehicle side and does not depend on a remote transmission network, thereby effectively improving the fault diagnosis reliability.

Description

technical field [0001] The invention relates to a vehicle fault diagnosis and data analysis system and a vehicle, belonging to the technical field of electric vehicle monitoring. Background technique [0002] During the operation of the vehicle, in order to improve the safety of the vehicle and the passengers, it is necessary to detect and diagnose the possible faults of the vehicle in real time. Among them, in the fault diagnosis of new energy vehicles, the risk of power battery temperature and voltage faults is relatively high, and the timeliness and accuracy of diagnostic results are highly required. [0003] The new energy vehicle remote intelligent monitoring system provides effective data support for the safe operation and fault diagnosis of new energy electric vehicles, so that new energy electric vehicles can predict possible problems in advance during market operation, and can also quickly and efficiently locate the market Vehicle problems provide effective protect...
