Embodiment 1

[0015] A control method for a vehicle-mounted information terminal, the method is based on a dual-system architecture of a real-time operating system and a graphical interface operating system, and its flow chart is as follows figure 1 shown, including:

[0016] In step S1, the vehicle-mounted information terminal is powered on, and the real-time operating system starts and controls the hardware function modules of the vehicle-mounted information terminal by default.

[0017] In the embodiment of the present invention, when the user starts the car, the vehicle information terminal starts to be powered on.

[0018] In the embodiment of the present invention, the real-time operating system can be started relatively quickly, usually in about 3 seconds.

[0019] The hardware function module includes one or more of a bluetooth module, a 3G network module, a GPS module, a radio module, a DVD module, a reversing video module, a digital TV module and a touch screen module.

Embodiment 2

[0042] A vehicle-mounted information terminal 10, the schematic diagram of its logical structure is as figure 2 As shown, the vehicle-mounted information terminal 10 includes: a real-time operating system module 100, a graphical interface operating system module 200, and hardware function modules 1 to hardware function modules n (n≥2), wherein:

[0043] The real-time operating system module 100 is used to start and control the hardware function module by default after the vehicle-mounted information terminal 10 is powered on, and judge whether the graphical interface operating system module 200 has been started. Part of the hardware function modules or all hardware function modules of the terminal 10 are taken over by the graphical interface operating system module 200;

[0044] The graphical interface operating system module 200 is configured to take over all or part of the hardware function modules controlled by the real-time operating system module 100 after the startup is...

Embodiment 3

[0047] A vehicle-mounted information terminal 10', the schematic diagram of its logical structure is as follows image 3 As shown, the vehicle-mounted information terminal 10' includes: a real-time operating system module 100', a graphical interface operating system module 200', and a hardware function module hardware function module 1~hardware function module n (n≥2). In this embodiment, the The real-time operating system module 100' includes an application control module 110 and a status monitoring module 120, wherein:

[0048] The application control module 110 is used to control the driver program of the hardware function module through the upper layer application, and output the OSD interface image to the display screen; The module or all hardware function modules are handed over to the graphical interface operating system module 200' to take over;

[0049] The state monitoring module 120 is used to judge whether the GUI operating system module 200' has been started, and...

Abstract

The embodiment of the invention discloses a vehicle-mounted information terminal and a control method thereof. Based on a double-system architecture having a real-time operating system and a graphical interface operating system, the method comprises the following steps that: after the vehicle-mounted information terminal is electrified, the real-time operating system starts and carries out default control on hardware functional modules of the vehicle-mounted information terminal; the real-time operating system judges whether starting of the graphical interface operating system is finished; and if the starting is finished, the real-time operating system transfers parts or all of the hardware functional modules of the vehicle-mounted information terminal to the graphical interface operating system for control. By employing the double-system architecture having the real-time operating system and the graphical interface operating system, the vehicle-mounted information terminal and the control method thereof provided by the embodiment of the invention are characterized by quick start of the real-time operating system and rich functions of the graphical interface operating system, so that the functions of the information terminal are richer, and performance is higher.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic information, in particular to a vehicle-mounted information terminal and a control method thereof. Background technique [0002] With the development of electronic information technology, the use of vehicle-mounted information terminals greatly facilitates the user's operation.
