Embodiment Construction

[0053] The gateway in the existing vehicle network is mainly for the routing of CAN network messages, and the design of its routing table mainly considers the interaction of CAN. And some slightly complicated hybrid gateways basically only realize the routing and forwarding between the same network, such as a gateway with both Ethernet switching and CAN switching, between Ethernet and CAN networks, can realize forwarding, but CAN The forwarding between Ethernet and Ethernet is mainly completed by the devices in each access network. As a result, the signal routing and forwarding efficiency between different buses is low.

[0054] The multi-bus hybrid routing method and gateway device of the present invention define a multi-bus, multi-protocol static routing scheme for the vehicle body network, and expand the method and mode of accessing the gateway in the vehicle body network on the basis of the current CAN static routing, and the routing of each bus The method can meet the ef...

Abstract

The invention discloses a multi-bus hybrid routing method and a gateway device. The method comprises the following steps of: receiving a first data unit from a source port in a current bus; matching afirst protocol corresponding to the current bus through a first preset rule, and analyzing the first data unit by adopting the first protocol to obtain data information in the first data unit and anID of a target port; based on the ID of the target port, matching a target bus where the target port is located through a second preset rule, the type of the target bus being different from that of the current bus; matching a second protocol corresponding to the target bus through the first preset rule, and packaging the data information by adopting the second protocol to form a second data unit;and sending the second data unit to the target port through the target bus. Routing of data unit transmission between different buses is achieved, and the data exchange and transmission efficiency isimproved.

Description

technical field [0001] The present invention relates to the technical field of new energy vehicle gateways, and more specifically, to a multi-bus hybrid routing method and a gateway device. Background technique [0002] Due to the rise of smart cars, the network architecture in vehicle systems is becoming more and more complex, and gateways with mixed high, medium and low buses such as Ethernet, CAN, and LIN have appeared. The routing and forwarding of signals between these different buses still rely on Each module has not yet defined a unified routing method for signal analysis and application layer forwarding. [0003] In the existing static routing gateway, only the processing of the CAN bus is defined, and the routing and forwarding of mixed buses such as LIN and Ethernet are not considered. The information transmission between various networks mainly depends on the terminal receiving the information The device analyzes and redistributes the information. As a result, v...
