Embodiment Construction

[0035] Such as figure 1 Shown, in one embodiment, a kind of electric vehicle fault handling method comprises the following steps:

[0036] Step S101 , the motor system monitor monitors the operation of the motor system according to a preset frequency, obtains the operation status of the motor system, and sends a corresponding operation status signal to the vehicle controller according to the operation status of the motor system.

[0037] The motor system is the power system in the electric vehicle, which drives the driving of the electric vehicle. The vehicle controller is the central controller of the electric vehicle, which controls each device part of the electric vehicle.

[0038] The motor system monitor obtains the running status of each part in the motor system. When a fault occurs in one of the parts, it generates a running status signal corresponding to the fault in the part according to the preset format, and sends the generated running status signal to the vehicle....

Abstract

An electric automobile fault handling method comprises the steps of enabling a motor system monitor to monitor running of a motor system according to preset frequency, obtain a running state of the motor system, and send corresponding running state signals to a full automobile controller according to the running state of the motor system; enabling an energy storage system monitor to monitor running of an energy storage system according to preset frequency, obtain a running state of the energy storage system and send corresponding running state signals to the full automobile controller according to the running state of the energy storage system; enabling the full automobile controller to receive the running state signals of both the motor system and the energy storage system, analyze the received running state signals, search fault grades corresponding to the running state signals and send running instructions to the motor system according to the fault grades; and enabling the motor system to run according to the running instructions. In addition, an electric automobile fault handling system is further provided. According to the electric automobile fault handling method and system, the faults of the motor system and the energy storage system can be detected timely, and the electric automobile is controlled to run according to the fault grades.

Description

【Technical field】 [0001] The invention relates to the field of automobile control, in particular to a method and system for handling faults of electric automobiles. 【Background technique】 [0002] The main components of an electric vehicle include a motor system and an energy storage system. The motor system is the power system in the electric vehicle, driving the driving of the electric vehicle. The energy storage system is a device that stores energy and provides power for electric vehicles. In the prior art, when the electric vehicle or the energy storage system fails, the occurrence of the failure cannot be detected in time, and the operation of the electric vehicle is controlled according to the specific situation of the failure. 【Content of invention】 [0003] Based on this, it is necessary to provide an electric vehicle fault handling method that can detect the faults of the electric energy system and the energy storage system in time and control the operation of ...
