Remote vehicle-mounted system and fault diagnosis, information acquisition and remote upgrading method thereof

Abstract

The invention discloses a remote vehicle-mounted system and a fault diagnosis, information acquisition and remote upgrading method thereof, and belongs to the technical field of networks, vehicle CANbuses and vehicle-mounted Ethernet. Technical key points are as follows: the system comprises a main controller, a diagnosis controller, an intelligent gateway, a wireless communication module, a remote server and an intelligent terminal, the main controller is connected with the diagnosis controller, the intelligent gateway and the wireless communication module. The wireless communication moduleis connected with the remote server, the remote server is connected with the intelligent terminal, the intelligent gateway is connected with the automobile ECU through the Ethernet, and the diagnosiscontroller is connected with the automobile ECU through a CAN bus, a K line and an LIN line. The beneficial effects of the invention are that the system irons out the fault diagnosis that a vehicle must enter a store or the bus support of other equipment is incomplete, can remotely obtain all related information of the vehicle, and solves a problem that the system cannot be upgraded during the operation of the vehicle.

Description

technical field [0001] The invention belongs to the field of network technology, vehicle CAN bus and vehicle Ethernet technology, and in particular relates to a remote vehicle system supporting vehicle Ethernet and methods for fault diagnosis, information acquisition and remote upgrade thereof. Background technique [0002] With the rapid development of network technology, using the network, people can not only realize long-distance communication and intercommunication, but also data transmission, video entertainment and so on. Everyone is now inseparable from the Internet.
