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 ...
