Embodiment Construction

[0020] The central control single-chip microcomputer module receives the car control CAN bus information data packets sent by the engine, gearbox, motor and battery assembly controllers in the car on the CAN bus network through the CAN communication module, including engine speed, engine torque, motor speed, Real-time vehicle status information of motor torque, battery voltage, battery current, battery power and gear position;

[0021] Based on the above information obtained by the central control single-chip computer, according to the SAE J1939 protocol, the conversion of the display unit, the analysis of the multi-energy distribution status of the vehicle, the coordinate distribution of the real-time working point of the engine and the coordinate distribution of the real-time working point of the motor are calculated, and the memory is used to record the battery since the vehicle was started. The last 24 minutes historical operating status of the battery;

[0022] Through th...

Abstract

The present invention relates to a CAN bus meter vehicle controlling information processing method for a hybrid power driven passenger car, which belongs to the automobile electronic intelligent meter field. The method is by the LAN connection of the CAN bus interface unit inside a singlechip and a standard controller arranged in the vehicle to receive the information data packet sent on the CAN bus network by each controller in the vehicle; by controlling the singlechip program to collect the vehicle controlling information of the hybrid power driven passenger car; by calculating and concluding to analyze out the integrative information and the history operation state of the stored vehicle; by the lattice type color liquid crystal screen to realize animated cartoon in the form of characters, sliding bar patterns, and flowing vectorgraphs; by the form of dynamic coordinate point and the dynamic movement curve in the two dimensional coordinate chart to display the vehicle controlling information of the hybrid power driven passenger car. The prevention improves the safety and the economical effect of the vehicle greatly, and is applicable for the characteristic of complex state and large information volume of the mechanical and electrical hybrid power driven passenger car.

Description

technical field [0001] The invention belongs to the field of automotive electronic smart meters, and specifically relates to a full-digital smart meter which is composed of a control single-chip microcomputer, a liquid crystal screen and its control circuit, a touch screen and its control circuit, and CAN bus nodes to provide display and diagnostic tools for hybrid electric buses information processing methods. Background technique [0002] Electromechanical hybrid bus is a new type of bus that has been developed in recent years and has broad prospects. Its low fuel consumption, low emission, high efficiency, energy saving and environmental protection will make it a good market in large and medium cities. Hybrid electric bus is a highly complex system integrating internal combustion engine power and electric motor power. The special multi-energy management structure makes computer intelligent control very necessary. The commonly used method is that the information between t...
