Automobile gateway controller and control method thereof

Abstract

The invention relates to an automobile gateway controller, which comprises a plurality of network control units used for receiving and transmitting network messages; the hardware network acceleration unit judges the type of the network message received by the network control unit and divides the network message into a forwarding message and an analysis message; the network control units notify the hardware network acceleration units after receiving the network messages, if the network messages are forwarding messages, the hardware network acceleration units directly forward the forwarding messages to the corresponding network control units in the multiple network control units, and if the network messages are the analysis messages, the hardware network acceleration units directly forward the forwarding messages to the corresponding network control units in the multiple network control units. And the hardware network acceleration unit sends the analysis message to a real-time core. According to the invention, through the automobile gateway controller based on the hardware network acceleration unit, forwarding messages which can be forwarded directly and analysis messages which need to be analyzed by an application layer are distributed to different hardware units for processing, so that the real-time performance and the stability of in-automobile message forwarding are improved.

Description

technical field [0001] The invention belongs to the field of automotive electronics, and relates to an automotive gateway controller and a control method thereof, more specifically, to an automotive gateway controller capable of distributing different types of network messages inside a vehicle to different hardware units for processing and a control method thereof. Background technique [0002] With the emergence of autonomous driving and smart cars, car functions are becoming more and more complex, and there are more and more electronic control units in the car. The automotive electronic architecture is developing towards a centralized architecture. According to different functions in the car, it is divided into different domain controllers. The automotive electronic unit is connected to the corresponding domain controller through the bus network, and the domain controllers are connected to the automotive gateway through the bus network. [0003] In order to support the var...
