Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted technology, and in particular to a method for sleeping and waking up a vehicle-mounted terminal device. Background Art

[0002] Automotive on-board devices refer to various devices installed on the car for the purpose of improving driving experience, enhancing vehicle functions, ensuring driving safety or providing entertainment and leisure. During the use of automotive on-board devices, it is often necessary to quickly start the on-board devices. At the same time, when the vehicle is not in use, the on-board devices must maintain relatively low power consumption.

[0003] In actual applications, the application of the vehicle-mounted device should be able to run quickly after being awakened when it is dormant, and the software system after awakening should be completely reliable, and consistent with the functional safety of cold start. However, the existing method cannot make the device enter the dormant state quickly and maintain very low power consumption. Moreover, when interactive use is required, the screen cannot be quickly turned on to start the vehicle-mounted application. Summary of the invention

[0004] The purpose of the present invention is to provide a method for sleeping and waking up a vehicle-mounted terminal device, aiming to solve the technical problems in the prior art that the device cannot quickly enter a sleep state, maintain very low power consumption, and cannot quickly light up the screen to start the vehicle-mounted application when interactive use is required.

[0005] To achieve the above object, the present invention adopts a method for sleeping and waking up a vehicle-mounted terminal device, comprising:

[0006] The vehicle-mounted equipment detects whether a specific sleep instruction from the main power control module is received in a normal working state;

[0007] When it is detected that a terminal in a normal working state has received a sleep command, the vehicle-mounted terminal is controlled to sleep;

[0008] The main power control module detects whether a wake-up command has been received;

[0009] When the wake-up command is received, the vehicle terminal device wake-up process begins.

[0010] Among them, when it is detected that the terminal in the normal working state has received a sleep instruction, the specific method of controlling the vehicle terminal to sleep is:

[0011] When it is detected that a terminal in a normal working state has received a sleep command, the vehicle terminal state is switched to a sleep preparation state, and the vehicle terminal is detected by the vehicle device to see whether the preset sleep conditions are met, and the vehicle terminal is controlled to sleep according to the detection result;

[0012] When the vehicle terminal enters the sleep state normally, each module enters the sleep exit and sleep power-off procedures in turn, and the vehicle device system saves the currently running memory to the storage;

[0013] When the vehicle terminal is forced to enter the dormant running state, the information of the unsatisfied conditions is saved, the delayed dormant time notification is broadcast, and the applications that do not meet the conditions are locked and dormant and exited; after all applications enter the dormant state, the dormant running state is entered;

[0014] The main power control module always detects whether the system current has reached the threshold value of the dormant state;

[0015] If the above threshold value is maintained for 10 seconds, it is marked as entering the sleep state. If it exceeds 120 seconds and the above threshold value is not reached, or the minimum current gate is not maintained for 10 seconds, it is marked as the sleep timeout mode, the main control power supply is cut off, and the forced power-off state is entered.

[0016] Among them, the specific method of detecting whether the vehicle terminal meets the preset sleep condition through the vehicle-mounted device and controlling the vehicle terminal to sleep according to the detection result is:

[0017] If the sleep conditions are met, a broadcast notification is sent to all modules and the system enters the sleep state. If the sleep conditions are not met, a broadcast notification is sent to all modules and the system enters the forced sleep state.

[0018] Among them, when the wake-up command is detected, the specific method of entering the vehicle terminal device wake-up process is:

[0019] When receiving the wake-up command, the main power control module determines whether the current state is in the sleep state. If it is in the sleep state, it will enter the power-on wake-up process;

[0020] If it is not in sleep mode, the vehicle-mounted device will enter the cold start power-on process.

[0021] During the power-on wake-up process, the kernel first wakes up and starts powering on each module. At the same time, the system copies the pre-wake-up data originally stored in the memory to the memory to resume execution.

[0022] Among them, the specific power-on process of the vehicle-mounted equipment entering the cold start is as follows:

[0023] The vehicle-mounted device is powered on and powered on. After the vehicle-mounted device is powered on, it performs functional tests and calibrations, and then loads and initializes the operating system to prepare for the running of the application program.

[0024] After that, load and start the application and activate the display;

[0025] The user interface then loads into standby mode.

[0026] Among them, the main power control module will automatically monitor the operating status when in use, and will sound an alarm if any abnormality occurs in the operation.

[0027] Among them, after powering on, the on-board equipment undergoes functional testing and calibration, including sensor, camera, and microphone functional testing, camera clarity inspection, and microphone volume calibration.

[0028] A method for hibernation and awakening of a vehicle-mounted terminal device of the present invention, the vehicle-mounted device detects whether a specific hibernation instruction of a main power control module is received in a normal working state; when it is detected that the terminal in a normal working state has received a hibernation instruction, the vehicle-mounted terminal is controlled to hibernate; after hibernation, the main power control module detects whether a wake-up instruction is received; when it is detected that a wake-up instruction is received, the vehicle-mounted terminal device wake-up process is entered, and the system used in the method for hibernation and awakening of a vehicle-mounted terminal device of the present invention is: a vehicle-mounted system capable of hibernation and awakening, including a low-power MCU main control power control module and a host SOC, wherein the MCU receives external hibernation and awakening instructions, and detects the working state of the host SOC and the system current at the same time, and the host SOC completes the hibernation and awakening process of controlling each application and functional module, completes the wake-up and hibernation operations of data storage and rapid recovery of the program, so that the whole set of equipment can quickly enter the hibernation state, maintain very low power consumption, and can quickly light up the screen to start the vehicle-mounted application when interactive use is required;

[0029] The MCU receives the car's wake-up and sleep commands through CAN or signal lines, and detects the status and current of the host SOC at the same time; when the entire machine enters sleep mode, the MCU notifies the host SOC to enter sleep mode, performs a safe or forced sleep process, and finally saves the memory data before sleep mode to the storage device, so that when it is woken up, it can be written back to the memory for fast execution and recovery. This method solves the technical problems in the prior art that the device cannot quickly enter sleep mode, maintain very low power consumption, and cannot quickly light up the screen to start the vehicle-mounted application when interactive use is required.
