Abstract

The invention discloses a failure diagnosis method, a fault diagnosis instrument and a system thereof, and also discloses a new energy vehicle, wherein, the fault diagnosis instrument comprises a receiving device, a processing device and an acquisition device; the receiving device is used for receiving collecting data of a battery and a driving motor through a communication interface; the processing device is used for obtaining diagnosis data after calculation according to the collecting data; and the acquisition device is used for determining state results of the battery and the driving motor according to the diagnosis data. By adopting the invention, all functions of a conventional OBD-II instrument (OBD is short for On-Board Diagnostic) can be achieved, and whether typical parts of the battery and the driving motor in the new energy vehicle operate normally can also be read and diagnosed, and so that the functions of the fault diagnosis instrument can be perfected.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a fault diagnosis method, a fault diagnosis instrument and its system, and a new energy vehicle. Background technique [0002] With the development of the modern automobile industry, the degree of electronicization of automobiles is increasing day by day, and the electronic control unit ECU (Electrical control unit) is widely used. dedicated microcontroller. It is the same as ordinary single-chip microcomputer, it is composed of microprocessor (CPU), memory (ROM, RAM), input / output interface (I / O), analog-to-digital converter (A / D), and shaping, driving and other large-scale integration. Circuit composition. [0003] The wide application of ECU makes the electronic control system (fuel injection system, automobile brake anti-lock braking system, safety air bag, etc.) increase continuously. These systems make the maintenance of automobiles extremely difficult. In order to facilitate ...
