[0002] The embodiments of the present application are based on and claim priority to Chinese Patent Application No. 202410825521.4, filed on June 25, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the field of automotive electronics, in particular to a sleep method, device and vehicle of SOC chip. BACKGROUND

[0004] With the rapid development of automotive electronics, electronic architecture gradually evolves from traditional distributed architecture to domain centralized architecture, and intelligent cockpit domain emerges as the times require. The intelligent cockpit of the vehicle integrates operating systems such as instrument systems and car systems, and the instrument systems and car systems of the vehicle run on the SOC chip of the vehicle, thereby realizing one chip and multiple systems. The vehicle also includes an MCU for controlling the SOC chip. In order to improve the performance and user experience of the vehicle, it is required that after the vehicle is started, the instrument system and the car system can be quickly started and enter a normal working state, thereby introducing a sleep mode of the SOC chip. In the sleep mode, the vehicle meets the low power consumption requirement, and the vehicle can quickly restore to the state before shutdown according to the information saved in the memory when the vehicle is started next time, thereby reducing the startup time.

[0005] However, at present, when it is detected that the sleep condition is met, if the SOC chip fails to enter the sleep state, the SOC chip will be directly controlled to be powered off. In this way, after the SOC chip fails to sleep, when the SOC chip needs to be started, the SOC chip needs to be cold started, thereby causing the startup time of the SOC chip to be long and affecting the user experience. SUMMARY

[0006] The present application provides a sleep method, device and vehicle of SOC chip, which is used to solve the problem that in the prior art, after sleep fails, when the SOC chip needs to be started, the SOC chip needs to be cold started, thereby causing the startup time of the SOC chip to be long and affecting the user experience.

[0007] In a first aspect, the present application provides a sleep method of SOC chip, applied to a microprocessor of a vehicle, and the microprocessor of the vehicle is electrically connected with a SOC chip of the vehicle. The method provided by the present application comprises:

[0008] When it is detected that the sleep condition is met, a sleep instruction is sent to the SOC chip;

[0009] read a number of times of SOC chip hibernation failures when no hibernation success signal based on the hibernation instruction feedback of the SOC chip is received within a first preset time length;

[0010] perform a restart operation and control the SOC chip to perform the restart operation when the number of times of SOC chip hibernation failures is less than or equal to a set number threshold, wherein the set number threshold is greater than or equal to 2;

[0011] re-send the hibernation instruction to the SOC chip;

[0012] determine that the SOC chip hibernation is successful when the hibernation success signal based on the hibernation instruction feedback of the SOC chip is received within the first preset time length.

[0013] In a second aspect, the present application further provides a hibernation device of an SOC chip, configured in a microprocessor of a vehicle, and the microprocessor of the vehicle is electrically connected with an SOC chip of the vehicle. The device provided by the present application comprises:

[0014] a data sending unit configured to send a hibernation instruction to the SOC chip when it is detected that a hibernation condition is met;

[0015] a data reading unit configured to read a number of times of SOC chip hibernation failures when no hibernation success signal based on the hibernation instruction feedback of the SOC chip is received within a first preset time length;

[0016] a system restart unit configured to perform a restart operation and control the SOC chip to perform the restart operation when the number of times of SOC chip hibernation failures is less than or equal to a set number threshold, wherein the set number threshold is greater than or equal to 2;

[0017] the data sending unit is further configured to re-send the hibernation instruction to the SOC chip;

[0018] a hibernation success determination unit configured to determine that the SOC chip hibernation is successful when the hibernation success signal based on the hibernation instruction feedback of the SOC chip is received within the first preset time length.

[0019] In a third aspect, the present application further provides a vehicle comprising a microprocessor and an SOC chip, the microprocessor is electrically connected with the SOC chip, and the microprocessor is configured to perform the method provided by the first aspect of the present application.

[0020] The application provides a sleep method and device of an SOC chip and a vehicle. When a sleep success signal fed back by the SOC chip based on a sleep instruction is not received within a first preset time length, it is indicated that the sleep of the SOC chip fails. At this time, the number of times of sleep failure of the SOC chip is read. When the number of times of sleep failure of the SOC chip is less than or equal to a set number threshold, it is indicated that the reason for the sleep failure of the SOC chip is probably caused by a system process. Therefore, the SOC chip is not powered off temporarily, but a restart operation is performed, and the SOC chip is controlled to perform the restart operation. The sleep instruction is sent to the SOC chip again. When the sleep success signal fed back by the SOC chip based on the sleep instruction is received within the first preset time length, it is determined that the sleep of the SOC chip succeeds, and the reliability of the sleep success of the SOC chip is improved. In this way, when the SOC chip is started, the SOC chip can be started hot, and therefore the start-up time of the SOC chip is shortened, and the user experience is improved.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. Hereinafter, the embodiments of the present application will be described with reference to the accompanying drawings.

[0034] The embodiment of the present application provides a sleep method of an SOC chip, applied to a microprocessor 101 of a vehicle, the microprocessor 101 of the vehicle (i.e. MCU) is electrically connected with an SOC chip 102 of the vehicle. As shown in FIG. 1, the SOC chip 102 includes an instruction interaction pin, a Sleep_Ready indication pin, a Sleep_Done indication pin, and a wake-up pin. The instruction interaction pin, the Sleep_Ready indication pin, the Sleep_Done indication pin, and the wake-up pin are electrically connected with the microprocessor 101 respectively.

[0035] The SOC chip 102 runs a vehicle machine system (such as an Android system) and an instrument system; the instruction interaction pin of the SOC chip 102 and the microprocessor 101 adopt serial port UART communication or SPI communication, for sending interaction instructions, such as sleep instructions and handshake instructions; after the vehicle machine system sleeps successfully, the microprocessor 101 can be notified by the Sleep_Ready indication pin that the vehicle machine system has slept successfully; after the instrument system sleeps successfully, the microprocessor 101 can be notified by the Sleep_Done indication pin that the instrument system has slept successfully; in addition, the microprocessor 101 can pull up the wake-up pin to wake up the SOC chip 102.

[0036] Specifically, as shown in FIG. 2, the method provided by the embodiment of the application comprises:

[0037] S201: When it is detected that the sleep condition is met, a sleep instruction is sent to the SOC chip 102.

[0038] Exemplarily, when the microprocessor 101 detects that the power supply of the whole vehicle stops or the whole vehicle network is disconnected, it is determined that the sleep condition is met, and a sleep instruction is sent to the SOC chip 102 based on the instruction interaction pin; the SOC chip 102 can start to perform a sleep operation in response to the sleep instruction. If the sleep is successful, the SOC chip 102 will feed back a sleep success signal to the microprocessor 101 based on the instruction interaction pin.

[0039] S202: It is judged whether the sleep success signal fed back by the SOC chip 102 based on the sleep instruction is received within a first preset time length; if yes, S203 is performed; if no, S204 is performed.

[0040] S203: It is determined that the SOC chip 102 sleeps successfully.

[0041] S204: The number of times of sleep failure of the SOC chip 102 is read.

[0042] S205: It is judged whether the number of times of sleep failure of the SOC chip 102 is less than or equal to a set number threshold; if no, S206 is performed; if yes, S207 is performed.

[0043] The set number threshold is greater than or equal to 2, for example, the set number is equal to 2 or 3 or 4 or the like.

[0044] S206: The SOC chip 102 is controlled to shut down, and the microprocessor 101 also performs a shutdown operation.

[0045] When the number of times of sleep failure of the SOC chip 102 is greater than the set number threshold, it is indicated that the sleep failure of the SOC chip 102 is not caused by the system process of the SOC chip 102, but caused by other physical reasons, and thus the SOC chip 102 is directly powered off, and the microprocessor 101 also performs the power-off operation. In this way, power consumption can be saved.

[0046] S207: performing a restart operation, and controlling the SOC chip 102 to perform the restart operation, and returning to perform S201.

[0047] When the number of times of sleep failure of the SOC chip 102 is less than or equal to the set number threshold, it is indicated that the sleep failure of the SOC chip 102 is possibly caused by the system process of the SOC chip 102; and thus the restart operation can be performed, and the SOC chip 102 is controlled to perform the restart operation, so as to improve the reliability of the sleep success of the SOC chip 102.

[0048] Specifically, the microprocessor 101 can record the restart source of the sleep failure exception, and then the microprocessor 101 performs the restart operation and controls the SOC chip 102 to be powered off, the microprocessor 101 reads the restart source, and when it is determined that the restart source is the restart source of the sleep failure exception, the number of times of sleep failure is recorded, and the SOC chip 102 is powered on and awakened, so that the SOC chip 102 performs a cold start, and returns to perform S201.

[0049] In summary, the embodiment of the present application provides a sleep method of a SOC chip. When a sleep success signal fed back by the SOC chip 102 based on a sleep instruction is not received within a first preset time period, it is indicated that the SOC chip 102 fails to sleep, and the number of times of sleep failure of the SOC chip 102 is read. When the number of times of sleep failure of the SOC chip 102 is less than or equal to a set number threshold, it is indicated that the sleep failure of the SOC chip 102 is possibly caused by the system process, and thus the SOC chip 102 is not powered off temporarily, but the restart operation is performed, and the SOC chip 102 is controlled to perform the restart operation. The sleep instruction is sent to the SOC chip 102 again. When the sleep success signal fed back by the SOC chip 102 based on the sleep instruction is received within the first preset time period, it is determined that the SOC chip 102 succeeds in sleeping, and the reliability of the sleep success of the SOC chip 102 is improved. In this way, when the SOC chip 102 is started, the SOC chip 102 can be started hot, and thus the start-up time of the SOC chip 102 is shortened, and the user experience is improved.

[0050] In some embodiments, the SOC chip 102 runs a car machine system and an instrument system, as shown in FIG. 3, S202-S205 can include:

[0051] S301: In the first preset time length, it is judged whether the sleep success signal based on the sleep instruction feedback of the car machine system of the SOC chip 102 is received, if not, S302 is executed; if yes, S304 is executed.

[0052] S302: The number of sleep failures of the car machine system is read.

[0053] S303: It is judged whether the number of sleep failures of the car machine system of the SOC chip 102 is less than or equal to the set number threshold, if yes, S207 is executed, if not, S206 is executed.

[0054] S304: When the sleep success signal based on the sleep instruction feedback of the instrument system of the SOC chip 102 is not received in the first preset time length, the number of sleep failures of the instrument system is read.

[0055] S305: It is judged whether the number of sleep failures of the instrument system of the SOC chip 102 is less than or equal to the set number threshold, if yes, S207 is executed, if not, S206 is executed.

[0056] In addition, as shown in FIG. 4, after S201, the method provided by the embodiment of the application further comprises:

[0057] S401: When the wake-up event is detected, it is detected whether the sleep success signal based on the sleep instruction feedback of the SOC chip 102 is received in the first preset time length; if not, S402 is executed; if yes, S403 is executed.

[0058] S402: Wait for a second preset time length, and return to execute S201.

[0059] S403: Wake up the SOC chip 102.

[0060] Based on the above S401-S403, when the wake-up event is detected, if the sleep success signal based on the sleep instruction feedback of the SOC chip 102 is not received in the first preset time length, it is indicated that the SOC chip 102 is in the process of sleeping at this time, and the sleep process of the SOC chip will not be interrupted, and the SOC chip 102 is woken up after the sleep of the SOC chip 102 is completed, which can avoid the inconsistency of the time sequence of the microprocessor 101 and the SOC chip 102, and cause serious abnormalities such as wake-up failure.

[0061] Further, the SOC chip 102 runs the car machine system and the instrument system, as shown in FIG. 5, S401-S403 can be specifically implemented as:

[0062] S501: When the wake-up event is detected, it is detected whether the sleep success signal based on the sleep instruction feedback of the car machine system of the SOC chip 102 is received within the first preset time length; if not, S502 is executed; if yes, S503 is executed.

[0063] Or, if yes, wake up the SOC chip 102.

[0064] It can be understood that when the wake-up event is detected, if the sleep success signal based on the sleep instruction feedback of the car machine system of the SOC chip 102 is not received within the first preset time length, it means that the car machine system of the SOC chip 102 is in the process of sleeping at this time, and the sleep process of the car machine system of the SOC chip 102 will not be interrupted, but the SOC chip 102 will be woken up after the car machine system of the SOC chip 102 is completely slept, which can avoid the inconsistency of the timing of the microprocessor 101 and the SOC chip 102, and cause serious abnormalities such as wake-up failure.

[0065] S502: Wait for a second preset time length, and return to execute S501.

[0066] S503: Detect whether the sleep success signal transmitted by the instrument system is received, if not, S504 is executed; if yes, S505 is executed.

[0067] S504: Wait for a second preset time length, and return to execute S503.

[0068] S505: Wake up the instrument system and the car machine system of the SOC chip 102.

[0069] It can be understood that when the wake-up event is detected, if the sleep success signal based on the sleep instruction feedback of the instrument system of the SOC chip 102 is not received within the first preset time length, it means that the instrument system of the SOC chip 102 is in the process of sleeping at this time, and the sleep process of the instrument system of the SOC chip 102 will not be interrupted, but the SOC chip 102 will be woken up after the instrument system of the SOC chip 102 is completely slept, which can avoid the inconsistency of the timing of the microprocessor 101 and the SOC chip 102, and cause serious abnormalities such as wake-up failure.

[0070] In addition, after S203, as shown in FIG. 6, the method provided by the embodiment of the application further comprises:

[0071] S601: When the wake-up event is detected, send a wake-up instruction to the SOC chip 102.

[0072] S602: Determine whether the wake-up success signal based on the wake-up instruction feedback of the SOC chip 102 is received within the first preset time length, if yes, S603 is executed; if not, return to execute S601.

[0073] S603: It is determined that the SOC chip 102 is successfully woken up.

[0074] Understandably, when the wake-up success signal based on the wake-up instruction feedback by the SOC chip 102 is not received within the first preset time length, it indicates that the wake-up of the SOC chip 102 fails, and multiple wake-ups of the SOC chip 102 can improve the probability of successful wake-up of the SOC chip 102.

[0075] Exemplarily, the SOC chip 102 runs the instrument system and the car machine system, as shown in FIG. 7, S601-S603 can be specifically implemented as:

[0076] S701: It is determined whether the wake-up success signal based on the wake-up instruction feedback by the instrument system of the SOC chip 102 is received within the first preset time length; if not, S702 is executed; if yes, S703 is executed.

[0077] S702: The instrument system of the SOC chip 102 is restarted, and S701 is returned.

[0078] Understandably, when the wake-up success signal based on the wake-up instruction feedback by the instrument system of the SOC chip 102 is not received within the first preset time length, it indicates that the wake-up of the instrument system of the SOC chip 102 fails, and multiple wake-ups of the instrument system of the SOC chip 102 can improve the probability of successful wake-up of the instrument system of the SOC chip 102.

[0079] S703: It is determined whether the wake-up success signal based on the wake-up instruction feedback by the car machine system of the SOC chip 102 is received within the first preset time length after the wake-up success signal feedback by the instrument system of the SOC chip 102 is received; if not, S704 is executed; if yes, S705 is executed.

[0080] S704: The car machine system of the SOC chip 102 is restarted, and S703 is returned.

[0081] S705: It is determined that the SOC chip 102 is successfully woken up.

[0082] Understandably, when the wake-up success signal based on the wake-up instruction feedback by the car machine system of the SOC chip 102 is not received within the first preset time length, it indicates that the wake-up of the car machine system of the SOC chip 102 fails, and multiple wake-ups of the car machine system of the SOC chip 102 can improve the probability of successful wake-up of the car machine system of the SOC chip 102.

[0083] It should be noted that the first preset time length and the second preset time length mentioned in the embodiments of the present application can be counted by a timer.
