A hydrogen energy vehicle vehicle network system

Abstract

The invention provides a whole vehicle network system for hydrogen energy vehicles, including a gateway controller, a vehicle brake module, a vehicle management module and an on-board automatic diagnosis system, wherein the gateway controller includes a first CAN network, a second CAN network, a third CAN network, and a third CAN network. The CAN network, the fourth CAN network, the first gateway encryption module and the second gateway encryption module, the input end of the first gateway encryption module is electrically connected to the first CAN network, and the output end of the first gateway encryption module is connected to the first gateway encryption module. The three CAN networks are electrically connected, the input terminal of the second gateway encryption module is electrically connected to the second CAN network, the output terminal of the second gateway encryption module is electrically connected to the fourth CAN network, and the vehicle brake module is electrically connected to the third CAN network. A CAN network is electrically connected, the vehicle management module is electrically connected to the second CAN network, the vehicle-mounted automatic diagnosis system includes a sixth CAN network and a seventh CAN network, the sixth CAN network is electrically connected to the third CAN network, The seventh CAN network is electrically connected to the fourth CAN network.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy vehicles, in particular to a hydrogen energy vehicle vehicle network system. Background technique [0002] With the vigorous development of hydrogen energy vehicles, more and more hydrogen energy vehicles have appeared in people's field of vision. However, due to the lack of protection awareness for the information security of hydrogen energy vehicles, competitors can simply intercept the matrix report of the entire vehicle. The text data cracks the control strategy and some algorithms of the vehicle, leading to information leakage; at the same time, due to the lack of information protection functions, functions such as remote start of the vehicle are easily used by illegal elements to steal vehicle or owner information. [0003] CAN is the abbreviation of Controller Area Network (hereinafter referred to as CAN), which is an ISO international standardized serial communication protocol. In...
