Embodiment Construction

[0032] It can be known from the background technology that the appearance of a large number of after-installed peripherals has a great impact on the stability of the vehicle network in the prior art.

[0033] The inventor of the present invention has studied the method of information interaction between the vehicle network and peripherals in the prior art, and found that the on-board diagnostic system (OBD: On Board Diagnostics) in the prior art is directly connected to the vehicle network, and the peripherals can be directly connected to the OBD The interface is connected to the vehicle network. However, because a large number of after-installed peripherals have not been approved by automobile manufacturers, and after-installed peripherals are usually low in cost and uneven in quality, they have a great impact on the stability of the vehicle network. Considering the safety of vehicles, the security of vehicle network data is particularly important. In addition, in the existi...

Abstract

The invention discloses a system and a method for carrying out information interaction between a complete vehicle network and a peripheral. The system used for carrying out information interaction between the complete vehicle network and the peripheral comprises a gateway control module, wherein the gateway control module is connected with the complete vehicle network, and the gateway control module is configured to be suitable for receiving request information of the peripheral, determining whether the request information is legal based on whether the request information can pass encryption authentication, sending first request illegal information to the peripheral if the request information is illegal, and sending feedback information corresponding to the request information if the request information is legal. The system and the method for carrying out information interaction between the complete vehicle network and the peripheral can improve data security of the complete vehicle network.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a system and method for information interaction between a vehicle network and peripheral devices. Background technique [0002] With the development of automotive electronic technology, more and more control systems have been built into the vehicle network, from driving, braking, steering system control to safety system and instrument alarm system, so as to realize data sharing. [0003] Controller Area Network (CAN: Controller Area Network) is a widely used fieldbus technology, which is designed for controller communication in the automotive environment, exchanging information between electronic control units (ECU: Electronic Control Unit) in the vehicle , forming a vehicle electronic control network. For example, CAN control devices are installed in the engine management system, gearbox controller, instrument equipment and electronic backbone system to form a CAN network....
