Example Embodiment

[0073] Example one

[0074] Figure 4 A schematic flow chart of an embodiment of a communication method for a vehicle-mounted gateway provided in this application, such as Figure 4 As shown, the communication method of the gateway provided in this embodiment is used for the conversion of messages between two protocols. Specifically, it may be the conversion from the Ethernet protocol to the CAN protocol. Among them, the first vehicle-mounted device may support the Ethernet protocol. The vehicle-mounted device, and the second vehicle-mounted device may be a vehicle-mounted device supporting the CAN protocol. The method specifically includes:

[0075] S101: The vehicle-mounted gateway receives the first message from the first vehicle-mounted device. The first message satisfies the first communication protocol supported by the first vehicle-mounted device, the first message is used to instruct the second vehicle-mounted device to perform a target operation, and the first message inc...

Abstract

The invention provides a communication method of a vehicle-mounted gateway, the vehicle-mounted gateway and an intelligent vehicle. When receiving a first message from a first vehicle-mounted device,the vehicle-mounted gateway identifies identification information in the first message, matches the identification information with preset identification information stored in the vehicle-mounted gateway, and does not send a second message unless matching is successful, and thus, the second message indicates a target operation executed by a second vehicle-mounted device. When the identification information of the first message cannot be matched with the preset identification information stored in the gateway, the vehicle-mounted gateway does not send the second information to control the second vehicle-mounted equipment to execute the target operation. Therefore, through the identification information of the first message set in the vehicle-mounted gateway of the automobile, the security threat brought to the vehicle-mounted network is reduced, and the security performance of the vehicle-mounted network of the automobile is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method of a vehicle-mounted gateway, a vehicle-mounted gateway and an intelligent vehicle. Background technique [0002] The controller area network (CAN) protocol is a serial communication protocol included in the ISO international standardization, and is widely used in the field of automotive technology to realize communication between on-board devices inside the car. Among them, each on-board device in the car is connected to the CAN bus to form the car's on-board network, and the on-board devices receive and send communication data based on the CAN protocol through the CAN bus. [0003] In the prior art, with the continuous development of communication technology and automobile technology, more and more vehicle-mounted devices provide the function of connecting to the Internet, so that automobiles can obtain more applications such as naviga...
