Serial data bus communication control system and method for hybrid electric vehicle

Abstract

The invention discloses a serial data bus communication control system for a hybrid electric vehicle. A vehicle control unit integrates a gateway function and is used for realizing signal routing andmessage routing between a power network segment and a hybrid power network segment and online monitoring of all communication nodes on the power network segment and the hybrid power network segment; acombination instrument integrates a gateway function and is used for realizing signal routing and message routing between the power network segment and the vehicle body network segment and online monitoring of all communication nodes on the power network segment and the vehicle body network segment; T-box is connected to the vehicle body network segment through a vehicle body network segment communication end, and the T-box is connected to the hybrid power network segment through the hybrid power communication end; and the power network segment, the vehicle body network segment and the hybridpower network segment are all connected into a vehicle diagnosis interface. Real-time acquisition of new energy data can be ensured, and real-time performance and reliability of network signal transmission can also be ensured.

Problems solved by technology

The traditional electrical components on modern cars are gradually becoming electronically controlled, and there are more and more electronic systems on the car. In these electronic devices, a large amount of information needs to be shared and transmitted to each other. The traditional wiring method is non-bus type, and the controller The signals between the domain controllers are all hard-wired signals; if all the signals are hard-wired, a large number of controller interfaces and wiring harnesses are required. According to the traditional wiring method, the body wiring harness will be large and complex, the installation space will be scarce, and the operation reliability will be reduced. , the difficulty of fault maintenance increases, and the cost of the line speed system is high
