Problems solved by technology

[0003] Many domestic manufacturers have begun to analyze the automotive communication protocol, but at present there is no effective and feasible analytical technology for the bus communication protocol, and more methods are used to design special working conditions and collect a large amount of data. When , the network communication protocol is obtained by trial and error, which is inefficient and consumes a lot of resources

Embodiment

[0065] Figure 5 , 6 They are respectively the topological diagrams of the vehicle control network before and after the gateway system is installed in the embodiment of the present invention. Below is the reference Figure 5 , 6 , with the goal of analyzing the clutch disengagement / engagement control command in the vehicle control network, the embodiments of the present invention will be described in detail.

[0066] Such as Figure 5 As shown, the bus topology of an unknown vehicle control network includes two CAN buses, and the network nodes involved in one of the CAN buses include: engine controller, gearbox controller, brake controller and vehicle control module. The transmission rate is 250Kbit / s, and it is named CAN250, such as Figure 5 , 6 As shown in the thin solid line; the network nodes involved in another CAN bus include: automatic clutch controller, motor controller, power controller and vehicle control module. The transmission rate of the CAN bus is 500Kbit...

Abstract

The invention discloses an automobile gateway system for inverse resolution of communication protocols. The gateway system is installed between a first network node and a second network node of an automobile control network, and comprises a first transceiver, a second transceiver, a third transceiver, a micro controller unit (MCU), a first memory, a second memory, a third memory and a fourth memory. Through the technical scheme, key control and state signals in the automobile control network can be effectively resolved, and accurate control of each key system is realized; and through the system, accuracy of protocol resolution is enhanced, the resolution efficiency is improved, and research resources are saved.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to an automobile gateway system for reverse analysis of a communication protocol of an automobile control network. Background technique [0002] There are more and more applications of bus technology in the domestic automobile market. As the cost of the industry decreases year by year, various development tools and solutions are gradually infiltrating, and there is no problem in the pure technical application level. The gap between China and foreign countries in terms of network development is mainly in the formulation and testing of communication protocols. The bus network design in foreign countries has been carried out for more than 20 years. The mature network communication protocols of various companies are obtained through years of accumulation, and many of them have formed network development protocols with their own characteristics. Domestic manufacturers need to develop i...
