Instrument special for new energy automobile

Abstract

The invention provides a digital instrument for a new energy automobile, which comprises an instrument shell and an inner circuit, wherein the instrument shell consists of a base, a surface glass cover, a panel, a combination switch control mechanism and a thin film transistor (TFT) liquid crystal display screen; and the inner circuit is connected with an external interface which passes through the base to communicate with other parts of an automobile body or an upper computer. A central processing unit of the inner circuit communicates with other parts of the automobile through a control area network (CAN) bus communication protocol, and acquires running states and failure information of the other parts of the automobile through a signal acquisition module, an automobile sensor and a sampling unit, and the running states and failure information are displayed by the display screen which is driven by a video main control processor and a decoder. The digital instrument integrates functions of a vehicle-mounted microcomputer, a battery management system, a whole vehicle subsystem running state and fault early-warning system, rear view during backing, ranging during parking, and the like, and has the functions of detecting, managing and displaying the working states and parameters and detailed faults of a battery, a motor, a motor controller, a body composition monitor BCM and the like, and allowing a user to query and set data.

Description

technical field [0001] The invention relates to the field of new energy vehicles, more precisely, relates to a digital instrument specially used for new energy vehicles. Background technique [0002] With the growing shortage of petroleum energy and the increasingly serious problem of environmental pollution, the development and utilization of new energy that can replace petroleum and is more energy-saving and environmentally friendly has attracted more and more attention from governments, and new energy vehicles have also emerged as the times require. [0003] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. New energy vehicles include hybrid vehicles, pure electric vehicles (inclu...

AI Technical Summary

Problems solved by technology

This solution is a typical instrument for internal combustion engine vehicles, which cannot display the working status and fault information of important components such as power motors, power motor controllers, and power batteries of new energy vehicles.

[0006] At present, instruments that can be used for new energy vehicles have gradually appeared on the market, but they are limited to the directional thinking of instrumentation for traditional internal combustion engine vehicles. Only a small amount of modification is made on the basis, and it is still unable to fully display the huge and complex work of new energy vehicles. state
