Abstract

The invention relates to the technical field of electric vehicles, in particular to an electric drive fault diagnosis system based on an artificial intelligence algorithm. According to the technical scheme, the system comprises an operation terminal, an electric drive detection confirmation module, a fault confirmation module, a diagnosis module, an automatic repair module and a manual repair module, and the operation terminal, the electric drive detection confirmation module, the fault confirmation module, the diagnosis module, the automatic repair module and the manual repair module are connected in sequence. The fault confirmation module is used for confirming faults of the electric drive, the diagnosis module is used for judging and analyzing specific faults of the electric drive, and the manual repair module is connected with the operation terminal. According to the method, the fault of a certain part of the electric drive can be quickly confirmed, the obtained diagnosis result of the electric drive is more accurate, the timeliness is obviously improved, the effectiveness of labor can be improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric drive fault diagnosis system based on an artificial intelligence algorithm. Background technique [0002] The electric drive system includes a motor, a motor controller and a transmission mechanism. Some electric vehicles have electric motors that drive the wheels directly. The electric drive mode of electric vehicles can basically be divided into two types: motor central drive and electric wheel drive. The motor central drive is a motor central drive system composed of an electric motor, a fixed speed ratio reducer, and a differential. In this drive system, since there is no clutch and transmission, the volume and quality of the mechanical transmission can be reduced; another type of motor The central drive system, which is similar to the layout of a fuel car with a front-wheel drive and laterally pinning the engine, integrates the electric motor, fixed s...
