Embodiment Construction

[0022] figure 1 Shown is the background image of the vehicle energy monitoring interface. The interface is divided into two parts: the upper part of the hybrid vehicle energy flow diagram and the lower part of the fault and alarm information prompt.

[0023] The vehicle energy flow schematic section lists the vehicle outline, engine, ISG motor, battery, wheel motor and other components, as well as the battery SOC status column bar, current value and voltage value display prompt area. The display of energy flow between the four main power system components of the engine, ISG motor, battery, and wheel motor is represented by the corresponding arrow area and the connecting rod area displaying different states. When there is energy flow passing through, the corresponding arrow or The connecting rod area is displayed in orange, otherwise, the background color is displayed or the outline of the arrow area is removed. In the interface, the engine and the ISG motor are connected to t...

Abstract

An integrative instrument system of a hybrid electric vehicle includes an instrument controller, a liquid crystal display terminal and a stepping motor instrument plate. The instrument controller includes a central processing module, a CAN information receiving and transmitting module, a serial communication module, a stepping motor drive module, a power voltage adjusting module and an external keystroke inputting module. The CAN information receiving and transmitting module receives the CAN information from a CAN bus interface and is connected to the central processing module, namely the CAN port of an SCM; the serial communication module is connected with the serial port of the SCM and the data receiving serial port of a colorful liquid crystal display terminal; the input end of the stepping motor drive module is connected with the I/O port of the SCM; the output end of the stepping motor drive module is connected with a 16-bus connector; the power voltage adjusting module converts an inputted 12V vehicle DC power into a 5V power to supply power for the power-consuming chips like the SCM, etc. The external keystroke inputting module is connected with one I/O port of the SCM for controlling the output of high-low levels. The integrative instrument system of a hybrid electric vehicle is characterized by multiple functions and low cost.

Description

technical field [0001] The invention relates to a comprehensive instrument system of a hybrid electric vehicle. Background technique [0002] The advancement of science is driving the progress of automotive instrumentation technology. With the development of electronics, optics and computer technology, especially the improvement of ECU performance, the full digital instrument controlled by ECU is mainly used on automotive instrumentation. As the electronic control unit, the single chip microcomputer plays the role of the core controller of the automobile instrument. Nowadays, the instrument panel centered on pointer instruments is common in traditional cars, including indications of some basic driving parameters, such as speedometer, engine tachometer, odometer, fuel gauge, water temperature gauge, various warning or warning lights, etc. . Due to the improvement of requirements for automobile environmental protection, safety, economy, intelligence, etc., car drivers need m...
