In one embodiment, the vehicle-mounted device further includes a memory 15 storing an alarm audio file, and the microkernel 102 reads an alarm audio signal from the alarm audio file stored in the memory 15. In one embodiment, before the micro core sends an alarm audio signal to the power amplifier through the digital signal processing chip, the method further includes: the microkernel 102 determines the fault type of the vehicle with fault according to the vehicle state information, and determines the corresponding alarm type according to the fault type; and the microkernel 102 acquires a corresponding alarm audio signal according to the alarm type. It will be appreciated that for different types of fault, the corresponding warning audio signal may be different to facilitate driver differentiation between different fault warnings. For example, the warning audio signal for excessive engine water temperature and the warning audio signal for insufficient remaining fuel may be different.

In summary, in the vehicle alarm method provided in the above embodiment, when the control system running on the large core of the vehicle-mounted device is in a breakdown state, if the vehicle fails, the micro-core of the vehicle-mounted device controls the speaker in the vehicle to issue an alarm, so that the problem that the vehicle alarm sound cannot be played normally when the vehicle fails due to the system breakdown of the vehicle-mounted device is solved, a driver can acquire failure information in time, driving safety is improved, and user experience is improved. In addition, the cost of the vehicle-mounted equipment does not need to be additionally increased.
Based on the same inventive concept of the foregoing embodiments, the present embodiment describes technical solutions of the foregoing embodiments in detail through specific examples. In this embodiment, the vehicle-mounted device is taken as a vehicle-mounted device as an example for description. Referring to fig. 3, a schematic structural diagram of the car machine provided in this embodiment is shown, where the car machine uses a System-on-a-chip (SoC) 20 with multiple cores and multiple heterogeneous cores, and the SoC20 has multiple Central Processing Units (CPUs), that is, core controllers such as a large core 21, a Graphics Processing Unit (GPU), and a micro core 22. The microkernel 22 has the highest authority, has a Static Random-Access Memory (SRAM) that is shared by itself, can directly run without depending on an operating system, and has control and Access to a Double Data Rate Synchronous Random-Access Memory (DDR) 23, a Flash24, and a Power Management Integrated Circuit (PMIC) 25, has a serial port configuration that is controlled independently, and can perform work state monitoring and on-chip Power-on timing configuration for a CPU and a GPU in the SoC. Two groups of serial ports (I2C/SPI/UART and the like) output by the SoC are switched by the Switch26 and then communicate with the DSP 27. When the system normally operates, the big core 21 controls a group of common serial ports to control the DSP27, and various rich audio frequencies such as media sound, navigation sound, electric voice, system prompt sound, automobile alarm sound and the like can be played. When the system crashes, the big core 21 loses the control of the memory, the Flash24 and the serial port, and can not control the DSP27 to make sound.

At the moment, videos, audio such as navigation, multimedia and telephone cannot be played, but all alarm sounds can be played, so that driving safety is guaranteed.
Here, the process of the vehicle warning is as follows:
1) the SoC keeps serial port communication with the DSP through Switch in design, the system communicates with the DSP through a large-core serial port during normal operation, and communicates with the DSP through a micro-core serial port during system crash.
2) When the car machine works normally, the operating system runs on the big core, and the big core controls the DSP to send out various audios including multimedia sounds, navigation sounds, electric voices and the like.
3) When the system crashes, the microkernel is started and is communicated with the DSP through independent serial port configuration. The MCU keeps working and acquires the automobile state information through the CAN bus.
4) When the automobile has a fault, the MCU is informed to the MCU through the CAN bus, the MCU reports the information to the micro-kernel of the SoC, and the micro-kernel receives the information and then drives the loudspeaker to send out an alarm sound through the built-in power amplifier by utilizing the sound file in the memory.
In summary, in the vehicle alarm method provided in the above embodiment, the main controller, i.e., the large core and the micro core of the SoC, is used to control the memory and the DSP under normal and breakdown conditions of the system, and the speaker can continue to send out the alarm sound of the vehicle when the vehicle system is broken down through the bus information obtained by the MCU without adding additional hardware, so as to save cost, ensure driving safety, and avoid property and life loss.
