Network controller of vehicle

Abstract

The invention relates to a controller, which aims at realizing the functions of the network controller that interconnecting different networks by gateway, collecting and analyzing the information of the systems in a vehicle and controlling output. The technical proposal of the invention is that the network controller of the vehicle comprises a micro-controller unit, a power management module connected with the micro-controller unit, a clock vibrator module, a reset module, a CAN communication module and/or a LIN communication module; wherein the micro-controller unit is communicated with equipment connected on the vehicle network through the CAN communication module or the LIN communication module to receive the information of the equipment and transmit control message to the equipment; the micro-controller unit is connected with other electronic devices, such as an instrument, a vehicle body control system and an upper computer in the vehicle through the CAN communication module on the micro-controller unit; a wireless access module is also arranged in the controller; and the micro-controller unit transmits the information to a remote terminal through the wireless access module, so as to forward a control command of the remote terminal to the devices in the vehicle.

Description

Technical field [0001] The invention relates to a controller, in particular to a network controller used in an automobile. Background technique [0002] With the development of the automobile industry and the degree of automation, more and more electronic control systems and communication systems are used in modern cars, such as body control systems, engine electronic control systems, automatic transmission control systems, anti-lock braking systems (ABS ), automatic cruise system (ACC) and on-board multimedia system. Data exchange is required between these systems, between the system and the display instrument of the car, and between the system and the car fault diagnosis system. For such a huge amount of data exchange, if the traditional data exchange method is still used, that is, the wire is used for point-to-point communication. The transmission method of the connection will be unimaginable, therefore, it becomes an inevitable choice to use the car network for data transmis...

AI Technical Summary

Problems solved by technology

The disadvantage of the existing gateway technology is that the traditional gateway only acts as a "translation" between devices of different protocols in the vehicle network system. It does not participate in the control of the vehicle network and cannot add new functions. No wireless access, no remote control and remote diagnosis functions; no fault storage and display functions
