Problems solved by technology

In this network, the engine is controlled by the energy assembly controller directly through the throttle controller to control the throttle. At the same time, there are two electric components, the ISG and the motor, and the structure is relatively complicated. At the same time, since the engine can only be controlled through the throttle , with certain limitations

Embodiment Construction

[0013] A kind of hybrid vehicle CAN network structure that the present invention proposes, in conjunction with accompanying drawing and embodiment detailed explanation is as follows:

[0014] The structure of the present invention is as figure 2 As shown, it includes the upper controller and the engine control unit, ISG control unit, display control unit and battery management unit connected to it through the CAN bus. The double solid line in the figure is the CAN bus, the single solid line is the electrical connection, and the dotted line is the mechanical connection.

[0015] This embodiment adopts a network speed of 500Kbps and a standard frame structure. The upper controller adopts the 16-bit single-chip microcomputer of Motorola Company, and receives the information sent by each control unit through the CAN bus, so as to understand the working status of each component. After calculation, control commands are sent to the engine control unit, ISG control unit, battery ma...

Abstract

The device consists of upper controller used in controlling each part of car, the ISG control unit used in controlling ISG according to the command from upper controlling to implement the generation of electricity and output of torque in electric, the motor control unit used in controlling the motor according to command of upper controller, the battery management unit used in checking the state of battery pack and gives an alarm for the bad condition of battery and emergency situation, the displaying control unit used in receiving all kinds of signal from CAN bus and displaying the state parameter and failure.

Description

technical field [0001] The invention belongs to the technical field of automobile electronic equipment, and in particular relates to a field bus structure design in a vehicle. Background technique [0002] The existing hybrid vehicle controller area network (hereinafter referred to as CAN) network has different network characteristics according to the structure of the hybrid vehicle itself (parallel connection, series connection, hybrid connection) and the control components. For example, the technology disclosed in the article "Research and Implementation of CAN Network in Parallel Hybrid Electric Vehicle" in "Industrial Control Computer" 2004 07, its structural block diagram is as follows figure 1 As shown, the network is composed of ISG controller (integrated starter generator, ISG for short), energy assembly controller, battery management system, CAN monitoring module and motor controller (the motor is an ordinary motor, which is different from ISG), Several nodes each ...
