Description

Dual system vehicle central control information system

technical field

The invention relates to the technical field of automotive electronics, in particular to a dual-system vehicle central control information system.

Background technique

At present, with the progress and development of the automobile industry, automobile manufacturers and passengers are gradually no longer satisfied with the improvement of mechanical performance and ride comfort, and gradually turn their attention to the intelligence of automobiles. The vehicle central control system has become the most direct embodiment of vehicle intelligence. The current vehicle central control system basically realizes functions such as GPS navigation system, multimedia entertainment system, and communication system. The traditional central control uses single-core ARM as the processor, which is paired with the Android operating system or the QNX operating system.

The Android operating system has been very popular in mobile phones and tablets. It has high development and powerful functions. Because it is an open source system and the promotion of Google, its development environment is very mature and there are many developers. Based on the Android operating system Application software is also very rich. However, because the Android operating system is a time-sharing operating system based on the embedded Linux kernel, the real-time performance of the system is relatively poor, and there may be a sense of lag during the operation process, which is easy to fragment, and the more programs are run, the longer it will be. . Moreover, the macro kernel structure is adopted, and the kernel driver, file system and many protocols are directly placed in the kernel space, which makes the kernel space very large, and many kernel drivers, file systems and protocols are developed by third parties. If there is a problem with the code provided by the third party, it may cause the system to crash. This also causes the Android operating system to have certain risks in the underlying operation of the vehicle's central control.

The QNX operating system is a commercial Unix-like distributed real-time operating system that complies with the POSIX specification. It has a wide range of applications in military, aerospace, railway, medical and industrial control and other fields. It has a unique microkernel structure. Operating system modules such as drivers, network protocols, and file systems are relatively independent from the kernel. Any module failure will not cause the kernel to crash, and each module can be dynamically loaded and unloaded as needed. Recompile the kernel; however, because the use of the system requires a commercial license, the price of the license is high, and there are fewer development materials and developers, which also results in fewer applications and higher development costs.

In view of the problems existing in the prior art, it is of great significance to provide a dual-system vehicle-mounted central control information system.
