Abstract

The invention provides a vehicle-mounted information system based on a master-slave mode and an implementation method thereof. The vehicle-mounted information system based on the master-slave mode comprises a master machine unit and a slave machine unit, wherein the master machine unit is based on a real-time operation system and the slave machine unit is based on an open source operation system. The vehicle-mounted information system based on the master-slave mode not only has the characteristics that a QNX system is high in operation safety, quick in start speed and high in reliability and also takes the characteristics of mobile internet, third-party application extension and openness of an android system; thus, the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle electronics, in particular to a vehicle information system based on a master-slave mode and its implementation method. Background technique [0002] At present, the mainstream operating systems used by the host computer of the vehicle information system include WinCE, QNX, Android system, etc., and the advantages and disadvantages of these operating systems are relatively obvious. The advantage of the QNX operating system is that it runs very fast and has reliable system security. It is a microkernel operating system that contains multiple layers or servers. Even if one of them is shut down or crashes, other layers or servers will not be affected. , with high stability and reliability. The QNX operating system has been selected by car manufacturers including Ford, Porsche, and BMW as the operating system for in-vehicle map, communication and entertainment systems. But as a relatively closed oper...
