New energy vehicle whole vehicle fault detection and diagnosis system

Abstract

The invention provides a new energy vehicle whole vehicle fault detection and diagnosis system, which is provided with intelligent diagnosis equipment, and the intelligent diagnosis equipment is connected with a whole vehicle controller through a whole vehicle OBD (On-Board Diagnostic); the whole vehicle controller is connected with a battery management system BMS through a CAN1, and the battery management system BMS is connected with a power battery; the whole vehicle controller is connected with the integrated control module through the CAN4, and the integrated control module is connected with the driving motor; and the whole vehicle controller is connected with the remote monitoring terminal, the remote monitoring terminal is wirelessly connected with the big data platform, the big data platform and the intelligent diagnosis equipment are provided with diagnosis software, the intelligent diagnosis equipment is also connected with the mobile phone / tablet computer terminal through local connection, the mobile phone / tablet computer terminal is provided with APP / software, and the APP / software modularly displays a diagnosis result. The system solves the technical problems of three-electricity fault detection and intelligent analysis of different vehicle types, and is complete in function and suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of physical adjustment control program control systems, and in particular relates to a new energy vehicle fault detection and diagnosis system. Background technique [0002] The state proposes to "focus on encouraging enterprises to have special instruments and software for fault diagnosis of complete vehicles and vehicle-mounted energy systems, drive systems, control systems and subsystems (core three-electric systems)." At present, the imperfections of new energy vehicle detection and diagnosis equipment on the market lie in: the maintenance technology of new energy vehicle service channels is weak, the market service process relies heavily on the technicians of OEMs and three electric manufacturers, and different three electric manufacturers , There are technical barriers between models, so there is no new energy vehicle three-electric fault detection and diagnosis equipment in the market; the existing fa...

At present, the imperfections of new energy vehicle detection and diagnosis equipment on the market lie in: the maintenance technology of new energy vehicle service channels is weak, the market service process relies heavily on the technicians of OEMs and three electric manufacturers, and different three electric manufacturers , There are technical barriers between models, so there is no new energy vehicle three-electric fault detection and diagnosis equipment in the market; the existing fault detection and diagnosis equipment is a single detection system free of charge by three electric manufacturers, and cannot be integrated through the vehicle CAN bus. Vehicle system detection; single detection function, can only rely on social GPS positioning system for simple data display, view data and positioning, can not solve the technical problems of new energy vehicle energy, drive, control and its subsystems integrated detection and diagnosis technology
