Embodiment 1

[0033] This example provides a dual-control vehicle terminal device based on X86 and ARM, including at least one CPU using the X86 architecture and one MCU using the ARM architecture;

[0034] Wherein, the CPU is used to run the android system and is connected with the display screen;

[0035] The MCU is used to monitor the CAN bus of the car and is connected to the CPU. The MCU feeds back the data of the car CAN bus to the CPU through the serial port in real time, and the CPU displays the data of the car CAN bus on the display through the vehicle condition information module. At the same time, the MCU controls the power supply state of the CPU through the power supply chip, and when the car stops, the power supply of the CPU is automatically turned off, and the MCU enters a deep sleep mode.

[0036] The structure diagram of this example is as follows figure 1 As shown, in this example, the MCU controls the power supply chip to supply power to the CPU. When the car is parked,...

Embodiment 2

[0040] On the basis of Embodiment 1, this example also includes a program detection module, which is used to detect and control the program run by the CPU; the MCU automatically detects whether the program run by the CPU is a necessary program, and if it is not a necessary program, then close the program And use hardware to cut off the peripheral device corresponding to the program; if necessary, wake up the program through a wake-up signal.

[0041] In the existing vehicle-mounted terminal devices, although the foreground shows that there are relatively few running programs, in fact, many programs are running in the background, and most of these programs are unnecessary, at least in the current state. The program running in the background will inevitably cause a lot of energy waste; in this example, the program detection module can automatically detect whether the program is running in the foreground or whether it has been running in the last few minutes. Minutes are running ...

Embodiment 3

[0044] This example provides a kind of method based on X86 and ARM dual control vehicle-mounted terminal device, at least comprises a CPU that adopts X86 architecture and an MCU that adopts ARM architecture; And comprises the following steps,

[0045] Automobile state judging step, described MCU controls the power supply state of CPU according to automobile state and by power supply chip, if automobile state is to stop the power supply of CPU, MCU enters deep sleep mode simultaneously; Otherwise enter monitoring step;

[0046] Monitoring step, the MCU monitors the CAN bus of the car, and feeds back the data of the CAN bus of the car to the CPU through the serial port in real time, and the CPU then displays the data of the CAN bus of the car on the display screen through the vehicle condition information module, and enters if a traffic accident occurs. SOS steps;

[0047] In the step of calling for help, both the CPU and the MCU can call the 3G module to send an emergency distr...

Abstract

The invention provides a dual-control vehicle-mounted terminal device and a method based on X86 and an ARM (Advanced RISC Machine). The dual-control vehicle-mounted terminal device at least comprises a CPU (Central Processing Unit) adopting an X86 framework and an MCU (Micro Controller Unit) adopting an ARM framework, wherein the CPU is used for running an android system and connected with a display screen; and the MCU is used for monitoring a CAN (Controller Area Network) bus of a vehicle and connected with the CPU. The MCU feeds the data of the CAN bus of the vehicle back to the CPU in real time, and the CPU displays the data on the display screen through a vehicle condition information module; and meanwhile, the MCU controls a power supply state of the CPU through a power chip, automatically turns off a power supply of the CPU when the vehicle is stopped, and enters into a deep sleep mode. According to the invention, the android system can be run through the CPU, the power consumption is effectively reduced, and the remote anti-theft function is also comprehensively achieved to meet the security and protection demands at the same time.

Description

technical field [0001] The invention relates to a vehicle-mounted terminal, in particular to a dual-control vehicle-mounted terminal device based on X86 and ARM, and to a method for a dual-control vehicle-mounted terminal device based on X86 and ARM. Background technique [0002] The entertainment effect of the traditional vehicle terminal system is average. After the introduction of the android system, the entertainment of the system can be greatly enhanced, but the android system cannot communicate with the CAN bus of the car, and the security function cannot be guaranteed, that is, the audio-visual entertainment of the android device, It is difficult to balance the basic functions such as telephone and navigation with the security function of the vehicle system at the same time; moreover, the power consumption of android devices is high, which is also a major challenge to the vehicle system. Contents of the invention [0003] The technical problem to be solved by the pr...
