Abstract

The invention discloses a vehicular double-system device and a starting method thereof. The vehicular double-system device comprises a Linux system and an Android system, wherein the Linux system is connected to a CAN system of a vehicle, the Linux system comprises a Linux kernel and a Linux sub-system; the Linux kernel is used for managing a power supply and a plurality of hardware drive programs; the Linux sub-system is used for loading a support library of a QT display framework and managing the QT display framework; and the Android system is in abutting joint with the Linux system and used for driving a plurality of application programs and sharing resources with the QT display framework. The vehicular double-system device disclosed by the invention has the beneficial effects that rapid response of important functions of the system is realized; an independent operation space is divided for an important function; a task is difficultly influenced by other tasks; and thus, the stability and the reliability of the task are ensured.

Description

technical field [0001] The present invention relates to the technical field of vehicle equipment, and more specifically, relates to a vehicle dual system device and a starting method thereof. Background technique [0002] With the increasing popularity of smart devices, the majority of users have increasingly higher requirements for intelligent programs for vehicle-mounted devices, and the original single-chip system is becoming more and more difficult to meet the increasingly rich market demand. At the same time, with the increasingly widespread application of the Android system, Android-based smart devices have gradually begun to appear on the automotive platform. However, due to the high complexity of the Android system, compared with the original single-chip platform, there are still some shortcomings. The application of the vehicle platform brings a series of difficulties. [0003] A kind of scheme that is more commonly used in the prior art is: use the MCU single-chip...
