[0005] The signal detection circuit is used to detect the signal type of the received signal, generate a first control signal according to the signal type, and send the first control signal to the logic processing module. The logic processing module is used to generate a second control signal according to the first control signal and send the second control signal to the power management module or the autonomous driving start module.

[0034] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0035] Please refer to Figure 1 , Figure 1 This is a structural diagram of a vehicle-mounted terminal provided in an embodiment of this disclosure, such as... Figure 1 As shown, the vehicle terminal includes: a signal detection circuit 100, a logic processing module 200, a power management module 300, and an autonomous driving start module 400. The signal detection circuit 100 is connected to the logic processing module 200 and the power management module 300, and the logic processing module 200 is connected to the power management module 300 and the autonomous driving start module 400.

[0036] The signal detection circuit 100 is used to detect the signal type of the received signal, generate a first control signal according to the signal type, and send the first control signal to the logic processing module 200. The logic processing module 200 is used to generate a second control signal according to the first control signal and send the second control signal to the power management module 300 or the autonomous driving start module 400. The second control signal is used to control the autonomous vehicle to switch from a first state to a second state. The first state is any one of a working state, a sleep state, and a power-off state, and the second state is any one of the working state, sleep state, and power-off state other than the first state.

[0037] It should be noted that the signal detection circuit 100 can receive signals from the vehicle itself or from outside the vehicle. For example, signals from the vehicle itself can include, but are not limited to, signals transmitted via the Controller Area Network (CAN), such as ignition (IGN) signals, door opening signals, seat adjustment signals, and brake pedal pressing signals; signals from outside the vehicle can include, but are not limited to, signals transmitted via the vehicle Ethernet, such as vehicle system upgrade signals and in-vehicle application upgrade signals.

[0038] Optionally, such as Figure 1As shown, the vehicle terminal may further include a signal receiving module 600, which is connected to the signal detection circuit 100 and is used to transmit received signals from the vehicle itself or from outside the vehicle to the signal detection circuit 100. The signal detection circuit 100 is used to detect the signal type of the received signal, which includes, but is not limited to, ignition signals, vehicle control signals, etc. The vehicle control signals can refer to signals used to control the vehicle, including but not limited to: door opening signals, window adjustment signals, seat adjustment signals, air conditioning adjustment signals, vehicle system upgrade signals, etc.

[0039] Furthermore, the signal detection circuit 100 generates a first control signal based on the signal type of the received signal and sends the first control signal to the logic processing module 200. The logic processing module 200 then generates a second control signal based on the first control signal, thereby controlling the autonomous vehicle to switch from a first state to a second state. For example, if the signal type of the signal received by the signal detection circuit 100 is an ignition signal, and if the autonomous vehicle is in a powered-off or hibernation state at this time, it can be assumed that the vehicle needs to be ignited to enter the working state. In this case, the signal detection circuit 100 generates a power enable control signal (i.e., the first control signal) and sends it to the logic processing module 200. The logic processing module 200 generates a second control signal based on the power enable control signal and sends it to the power management module 300. This second control signal is used to control the power management module 300 to perform power-on, thereby controlling the autonomous vehicle to switch to the working state.

[0040] It should be noted that the signal type of the signal received by the signal detection circuit 100 can also be other possible cases. Therefore, the first control signal generated by the signal detection circuit 100 can also be other possible cases. Correspondingly, the second control signal generated by the logic processing module 200 and the function used by the second control signal can also be other possible cases. These will be explained in detail in subsequent embodiments, and will not be elaborated on here.

[0041] In this embodiment, the signal detection circuit 100 generates a first control signal based on the signal type of the received signal and sends it to the logic processing module 200. The logic processing module 200 generates a second control signal based on the first control signal and sends the second control signal to the power management module 300 and the autonomous driving start module 400. The power management module 300 can power on or off the autonomous vehicle, thereby enabling the autonomous vehicle to enter a working state or a sleep state when powered on and a shutdown state when powered off. The autonomous driving start module 400 can control the autonomous vehicle to start autonomous driving, thereby enabling the autonomous vehicle to enter a working state. Figure 2As shown, the second control signal can control the autonomous vehicle to switch between operating, sleep, and power-off states, effectively improving the flexibility of autonomous vehicle control. Furthermore, the autonomous vehicle can be controlled to switch from operating or power-off states to a low-power sleep state, thereby effectively reducing energy consumption. The ability to quickly switch from sleep to operating or power-off states also achieves the goal of rapid vehicle start-up or energy saving.

[0042] Optionally, the signal detection circuit 100 is configured to generate a power enable control signal based on the ignition signal when the received signal is detected to be an ignition signal, and send the power enable control signal to the logic processing module 200 and the power management module 300. The logic processing module 200 is configured to generate a second control signal based on the power enable control signal. The second control signal is configured to control the power management module 300 to perform power-on and to control the autonomous driving start module 400 to start autonomous driving, so as to control the autonomous driving vehicle to switch to the working state. The first control signal includes the power enable control signal, and the second state is the working state.

[0043] It should be noted that after generating a power enable control signal based on the ignition signal, the signal detection circuit 100 may send the power enable control signal to the power management module 300 and the logic processing module 200 simultaneously, or sequentially. In an optional embodiment, after receiving the power enable control signal, the power management module 300 performs a power-on operation on the autonomous vehicle. At this time, the power management module 300 supplies power to the autonomous vehicle. If the autonomous driving start module 400 is not activated, the autonomous vehicle may be in a dormant state.

[0044] Alternatively, in another implementation, when the power management module 300 receives a power enable control signal and a second control signal sent by the logic processing module 200, and when the autonomous driving start module 400 receives the second control signal, the power management module 300 performs a power-on operation on the autonomous vehicle, thereby controlling the autonomous vehicle to enter the working mode.

[0045] For example, an autonomous vehicle can be in a powered-off state. If the signal detection circuit 100 receives an ignition signal, it generates a power enable control signal and sends it to the power management module 300 and the logic processing module 200. The logic processing module 200 generates a second control signal based on the received power enable signal and sends it to the power management module 300 and the autonomous driving start module 400. The power management module 300 then performs a power-on operation based on the received power enable control signal and the second control signal. The autonomous driving start module 400 starts autonomous driving based on the received second control signal, thus putting the autonomous vehicle into operating mode. Alternatively, the autonomous vehicle can also be in a dormant state, where the signal detection circuit 100 and the logic processing module 200 switch the autonomous vehicle to operating mode upon receiving an ignition signal; this will not be elaborated further here.

[0046] In this way, when the signal detection circuit 100 receives the ignition signal, it generates a power enable control signal and sends it to the power management module 300 and the logic processing module 200. This enables the logic processing module 200 to generate a second control signal to control the autonomous vehicle to enter the working state, thereby enabling the autonomous vehicle to quickly switch from the power off state or the hibernation state to the working state, so as to realize the rapid start of the autonomous vehicle.

[0047] Optionally, the signal detection circuit 100 is configured to generate a wake-up signal based on the vehicle control signal and send it to the logic processing module 200 when the received signal is detected to be a vehicle control signal. The logic processing module 200 is configured to generate a second control signal based on the wake-up signal. The second control signal is configured to control the power management module 300 to maintain power supply so as to control the autonomous vehicle to switch to a sleep state, or the second control signal is configured to control the autonomous driving start module 400 to start autonomous driving so as to control the autonomous vehicle to switch to a working state. The first control signal includes the vehicle control signal, and the second state is either a sleep state or a working state.

[0048] It should be noted that the vehicle control signal can refer to a signal used to control the vehicle. For example, when the autonomous vehicle is in a powered-off state, if the signal detection circuit 100 detects a door opening signal, it generates a wake-up signal and sends it to the logic processing module 200. The logic processing module 200, based on the wake-up signal, knows that the autonomous vehicle needs to be woken up, and generates a second control signal to send to the power management module 300 to control the power management module 300 to maintain power supply, thereby controlling the autonomous vehicle to enter a sleep state. In this way, the autonomous vehicle can switch from a working state or a powered-off state to a sleep state according to the vehicle control signal, effectively reducing vehicle energy consumption and making the control of the autonomous vehicle more flexible, no longer limited to switching between working and powered-off states.

[0049] Alternatively, please refer to further details. Figure 3 The signal detection circuit 100 includes a first chip 101 and an OR gate circuit 102. The first chip 101 is connected to the OR gate circuit 102, and the OR gate circuit 102 is connected to the logic processing module 200 and the power management module 300. The first chip 101 is used to send the received signal to the OR gate circuit 102, and the OR gate circuit 102 is used to generate a first control signal according to the signal type of the received signal, and send the first control signal to the logic processing module 200 and / or the power management module 300.

[0050] It should be noted that, such as Figure 3 As shown, the first chip 101 may include a CAN transceiver chip and an in-vehicle Ethernet physical layer (PHY) chip. The CAN transceiver chip is used to detect dominant levels from the vehicle's CAN network and convert them into high-level signals for output to the OR gate circuit 102. The in-vehicle Ethernet PHY chip is used to detect in-vehicle Ethernet message signals from the vehicle body or in-vehicle communication unit network and convert them into high-level signals for output to the OR gate circuit 102.

[0051] In this embodiment, after receiving a high-level signal transmitted by the CAN transceiver chip or the vehicle Ethernet PHY chip, the OR gate 102 performs an OR operation on the high-level signal to generate a first control signal. For example, it generates a power enable control signal and sends it to the power management module 300 and the logic processing module 200, or it generates a wake-up signal and sends it to the logic processing module 200. Furthermore, by performing an OR operation on the received high-level signal, different first control signals can be generated by the OR gate 102. This allows the logic processing module 200 to generate a second control signal with corresponding function based on the first control signal, thereby enabling the autonomous vehicle to switch between working, dormant, and powered-off states, improving the flexibility of autonomous vehicle control.

[0052] Optionally, such as Figure 3 As shown, the signal detection circuit 100 further includes an analog-to-digital (AD) acquisition circuit 103, which is connected to the first chip 101, the OR gate circuit 102, and the logic processing module 200. It should be noted that after receiving the first control signal sent by the OR gate circuit 102, the logic processing module 200 does not know which signal the OR gate circuit 102 received that generated the first control signal. Therefore, the logic processing module 200 can control the AD acquisition circuit 103 to acquire signals from the IGN signal transmission line, the CAN transceiver chip signal output line, and the vehicle Ethernet PHY chip signal output line via the AD input (AD-IN) signal path. This allows it to determine which output line the OR gate circuit 102 is based on for generating the first control signal. The AD acquisition circuit 103 then sends this result to the logic processing module 200, enabling the logic processing module 200 to determine which signal the first control signal is based on, and subsequently generate the corresponding second control signal. For example, if the first control signal is generated based on the ignition signal received from the IGN signal transmission line by the OR gate circuit 102, then the logic processing module 200 can generate a second control signal to control the power management module 300 to perform power-on and control the autonomous driving start module 400 to start autonomous driving, thereby controlling the autonomous driving vehicle to enter the working state and effectively ensuring that the autonomous driving vehicle can quickly and accurately achieve state switching.

[0053] Alternatively, please refer to Figure 4The logic processing module 200 includes a microcontroller unit (MCU) 201 and a real-time clock (RTC) circuit 202. The MCU 201 is connected to the RTC circuit 202, and the RTC circuit 202 is used to wake up the MCU 201 according to a preset wake-up period. The MCU 201 is connected to the OR gate circuit 102, the power management module 300, and the automatic driving start module 400. The MCU 201 is used to generate the second control signal.

[0054] It should be noted that the preset wake-up period can be set by the MCU 201. The MCU 201 and the RTC circuit 202 can be connected through an internal integrated circuit (I2C). The MCU 201 sets the preset wake-up period of the RTC circuit 202 through I2C. Thus, the RTC circuit 202 can wake up the MCU 201 based on the preset wake-up period in the sleep state, thereby ensuring that the MCU 201 can maintain power supply control in the sleep state and avoid the MCU 201 being completely powered off and shut down. This ensures that the autonomous vehicle can maintain a certain period of sleep state, reduce vehicle power consumption, and also enables rapid startup from the sleep state to the working state.

[0055] Optionally, the logic processing module 200 may further include a storage chip, such as a flash memory chip 203, which communicates with the serial peripheral interface (SPI) of the MCU 201 to store the sleep and wake-up logs of the MCU 201.

[0056] Alternatively, please refer to Figure 5 The power management module 300 includes a first power supply 301 and a second power supply 302, which are connected to the MCU 201. The first power supply 301 supplies power to the MCU 201 and the signal detection circuit 100. The second power supply 302 supplies power to the autonomous driving start module 400, and the MCU 201 controls the power-on or power-off of the second power supply 302.

[0057] For example, the first power supply 301 may be a power management integrated circuit (PMIC) power supply, which supplies power to the MCU 201 and the signal detection circuit 100 to ensure that the autonomous vehicle is constantly powered in both operating and sleep states. Additionally, after the vehicle is turned off and enters the shutdown state, the MCU 201 can perform power self-holding control on the first power supply 301 to prevent it from completely losing power. The second power supply 302 may be a direct current to direct current (DCDC) power supply, used to power the autonomous driving startup module 400, thereby ensuring the normal startup of autonomous driving.

[0058] In this embodiment, the MCU 201 can control the power-on and power-off of the second power supply 302. For example, in the sleep state, it controls the second power supply 302 to power off, thereby effectively saving power consumption of the autonomous vehicle; in the working state, it controls the second power supply 302 to power on, so as to ensure that the second power supply 302 can supply power to the autonomous driving start module 400, and ensure the normal start-up and driving of the autonomous vehicle.

[0059] Alternatively, please refer to Figure 6 The autonomous driving startup module 400 includes a microprocessor unit (MPU) 401, a graphics processing unit (GPU) 402, and a random access memory (RAM) 403. The MPU 401 is connected to the logic processing module 200 (e.g., MCU 201), the GPU 402 is connected to the MPU 401 via an internal bus, and the RAM 403 is connected to both the GPU 402 and the MPU 401 via a double data rate (DDR) bus. For example, after receiving a second control signal from the logic processing module 200, the MPU 401 quickly completes the autonomous driving sensor initialization and then calls the GPU 402 to run the autonomous driving artificial intelligence (AI) algorithm, thereby starting autonomous driving. The RAM 403 stores the autonomous driving initialization program and the AI ​​algorithm business processing program; in sleep mode, the RAM 403 can retain the autonomous driving sensor initialization program, and upon being woken up, directly execute the AI ​​algorithm running phase, thereby ensuring that the autonomous vehicle quickly starts autonomous driving to enter the working state.

[0060] Optionally, such as Figure 1As shown, the vehicle terminal provided in this embodiment of the present disclosure also includes an autonomous driving sensor 500, including but not limited to cameras, radar, navigation and other devices, for providing external environment perception, thereby assisting autonomous vehicles in achieving autonomous driving.

[0061] This disclosure also provides an autonomous driving vehicle, including the in-vehicle terminal described in the above embodiments. The autonomous driving vehicle includes all the technical features of the in-vehicle terminal described above, and therefore can achieve the technical effects achievable by the aforementioned in-vehicle terminal. To avoid repetition, further details are omitted here.

[0062] Please refer to Figure 7 , Figure 7 This is one of the flowcharts of a control method for an autonomous vehicle provided in this disclosure, applied to the autonomous vehicle described above. For example... Figure 7 As shown, the method includes the following steps:

[0063] Step S701: When the autonomous vehicle is in the first state, switch the autonomous vehicle from the first state to the second state according to the signal detection state of the autonomous vehicle.

[0064] The first state can be any one of the following: working state, hibernation state, and power-off state. The second state can be any one of the following: working state, hibernation state, and power-off state, except for the first state. For example, an autonomous vehicle can switch from the working state to the power-off state or hibernation state, or from the hibernation state to the power-off state or working state, or from the power-off state to the working state or hibernation state.

[0065] In this embodiment, the autonomous vehicle can switch from a first state to a second state based on signal detection status, such as whether an ignition signal is detected. For example, if the autonomous vehicle is in a powered-off state and detects an ignition signal, it can switch to an operating state or a sleep state; if the autonomous vehicle is in an operating state and does not detect an ignition signal, it can switch to a sleep state, thereby controlling the autonomous vehicle to enter a low-power mode and effectively saving power consumption. Of course, the switching between the operating state, sleep state, and powered-off state of the autonomous vehicle can also be other possible situations, which will be specifically illustrated in subsequent embodiments and will not be listed in detail here.

[0066] In this embodiment, the autonomous vehicle can switch between operating, sleep, and power-off states based on its own signal detection status. This allows the autonomous vehicle to move beyond simply switching between operating and power-off states, making its control more flexible. Furthermore, by adding a sleep state, the autonomous vehicle can enter a low-power mode, effectively saving power consumption.

[0067] Optionally, step S701 may specifically include:

[0068] When the autonomous vehicle is powered off, if the signal detection status indicates that a target signal has been detected, the signal type of the target signal is determined.

[0069] If the target signal is an ignition signal, control the autonomous vehicle to switch to operating mode; or, if the target signal is a vehicle control signal, control the autonomous vehicle to switch to sleep mode.

[0070] In this embodiment of the disclosure, if an ignition signal is detected when the autonomous vehicle is in a powered-off state, for example, if the signal detection circuit detects an ignition signal, it indicates that the vehicle needs to be started, and the autonomous vehicle is controlled to switch to a working state.

[0071] Alternatively, if a vehicle control signal, such as a door start signal, is detected when the autonomous vehicle is powered off, meaning no ignition signal is detected when the vehicle is powered off, it indicates that the vehicle is not intended to be started. In this case, the autonomous vehicle is switched from the powered off state to a low-power sleep state, thereby reducing the vehicle's power consumption and allowing the vehicle to be in a standby state. This enables the vehicle to quickly switch to the working state when an ignition signal is received.

[0072] Optionally, when the autonomous vehicle is powered off, if a target signal, such as an ignition signal or a vehicle control signal, is detected, the PMIC power supply in the power management module is powered on. The PMIC power supply supplies power to the logic processing module, thereby enabling the constant power section of the autonomous vehicle to start working, preparing for entering the working state or sleep state. The logic processing module further determines the signal type of the target signal. For example, the logic processing module uses the AD acquisition circuit in the control signal detection circuit to collect signals on different signal transmission lines to determine from which signal transmission line the target signal was collected, thus determining the target signal type. If the target signal is an ignition signal, the logic processing module fully powers on the DC-DC power supply in the power management module and sends a second control signal to the autonomous driving start module to start autonomous driving, thereby enabling the autonomous vehicle to enter the working state; or, if the target signal is a vehicle control signal rather than an ignition signal, the logic processing module controls the DC-DC power supply section and controls the autonomous driving start module to complete initialization, controlling the autonomous vehicle to enter the sleep state. This allows autonomous vehicles to switch to either operating or sleep mode by determining the type of the detected target signal when powered off. This makes the control of autonomous vehicles more flexible and allows them to move beyond just being powered off or operating, enabling them to enter a low-power sleep mode and effectively save power consumption.

[0073] Optionally, step S701 may further include:

[0074] If the signal detection status indicates that no ignition signal is detected while the autonomous vehicle is in operation, the autonomous vehicle is controlled to switch to a sleep state.

[0075] If the number of times the autonomous vehicle is woken up within a first preset time period is greater than a preset number when the autonomous vehicle is in a dormant state, the autonomous vehicle is controlled to switch to a shutdown state.

[0076] In this embodiment, when the autonomous vehicle is in operation, if no ignition signal is detected, it indicates that the vehicle may want to stop. Therefore, the autonomous vehicle is controlled to switch to a low-power sleep state to save power. After entering sleep mode, the autonomous vehicle can periodically perform a wake-up service based on a preset wake-up cycle. For example, this could be a wake-up of the MCU in the logic processing module. Wake-up refers to powering on the MCU to ensure it can control other modules or units. If the number of wake-ups within a first preset duration exceeds a preset number (i.e., no ignition signal to start the autonomous vehicle is received within the first preset duration), the autonomous vehicle is controlled to enter a shutdown state to avoid excessive power consumption due to excessive wake-ups. For example, each wake-up triggers a power-up on the MCU, and frequent power-ups waste power. Therefore, by judging the number of wake-ups within the first preset duration in sleep mode, the power consumption of the autonomous vehicle can be effectively reduced.

[0077] It should be noted that if an ignition signal is received when the autonomous vehicle is in a dormant state, it indicates that the vehicle needs to be started. The autonomous driving start module is then controlled to activate the autonomous driving system, thereby controlling the autonomous vehicle to enter the working state.

[0078] Optionally, step S701 may further include:

[0079] When the autonomous vehicle is in operation, if the signal detection status is a power-off signal detected, determine whether an ignition signal is detected within a second preset time period.

[0080] If no ignition signal is detected within the second preset time period, the autonomous vehicle is controlled to switch to the power-off state; or, if an ignition signal is detected within the second preset time period, it is determined whether an ignition signal is detected again within the second preset time period.

[0081] In this embodiment, when the autonomous vehicle is in operation, if a shutdown signal is detected, it will not immediately shut down. Instead, it will further determine whether an ignition signal is detected within a second preset time period. If not, it indicates that autonomous driving is no longer desired, and the DC-DC power supply in the power management module will be switched off to control the autonomous vehicle to the shutdown state. If an ignition signal is detected within the second preset time period, it indicates a possible erroneous operation, and the process of determining whether an ignition signal is detected within the second preset time period will continue until the autonomous vehicle switches to the shutdown state. In this way, by determining whether an ignition signal is detected within the second preset time period, accurate switching of the autonomous vehicle's state can be achieved, avoiding the impact of erroneous operations on the state switching of the autonomous vehicle.

[0082] Optionally, step S701 may further include:

[0083] If, while the autonomous vehicle is in a dormant state, the signal detection status indicates that an ignition signal has been detected, the autonomous vehicle is controlled to enter the operating state; or...

[0084] If the signal detection status indicates that no ignition signal or vehicle control signal is detected when the autonomous vehicle is in a dormant state, and the number of times the autonomous vehicle is woken up within a first preset time period is greater than a preset number, the autonomous vehicle is controlled to switch to a shutdown state.

[0085] In this embodiment of the disclosure, when the autonomous vehicle is in a dormant state, it can periodically perform a wake-up service based on a preset wake-up cycle. In the dormant state, if an ignition signal is detected, indicating a desire to start autonomous driving, the vehicle is controlled to enter a working state. If no ignition signal or vehicle control signal is detected, and the number of wake-ups within a first preset duration exceeds a preset number, the vehicle is controlled to enter a shutdown state. This avoids excessive power consumption due to excessive wake-ups, such as the MCU powering on once per wake-up, which wastes power. Therefore, by judging the number of wake-ups within the first preset duration in the dormant state, the power consumption of the autonomous vehicle can be effectively reduced.

[0086] Optionally, the method further includes:

[0087] If a vehicle control signal is detected but no ignition signal is detected while the autonomous vehicle is in a dormant state, the autonomous vehicle shall remain in the dormant state.

[0088] In this embodiment of the disclosure, when the autonomous vehicle is in a dormant state, if a vehicle control signal, such as a door opening signal or a seat adjustment signal, is detected, but an ignition signal is not detected, it indicates that only the control of the vehicle itself is required, rather than the start of autonomous driving. Therefore, the autonomous vehicle is kept in a dormant state, thereby maintaining the autonomous vehicle in a low-power standby state.

[0089] To better understand, the following examples illustrate the switching process between working, dormant, and powered-off states of autonomous vehicles.

[0090] Please refer to Figure 8 , Figure 8 This is a second flowchart of a control method for an autonomous vehicle provided in this disclosure embodiment, as shown below. Figure 8 As shown, when the autonomous vehicle is in a powered-off state, the method includes the following steps:

[0091] S11. Detect whether an ignition signal (IGN) or vehicle control signal is received, that is, whether a vehicle wake-up source signal is received.

[0092] S12, the OR gate circuit receives any wake-up source (i.e., IGN or vehicle control signal);

[0093] S13 then controls the PMIC power supply to start and power on, and,

[0094] S14. Steps to start the acquisition wake-up source via MCU;

[0095] S15. Determine if the wake-up source is IGN;

[0096] S16. If so, the DC-DC converter is fully powered on by the MCU, and the autonomous driving module is fully activated, and the autonomous driving sensors enter the working state.

[0097] S17. Control the autonomous vehicle to enter the working state;

[0098] S18. After step S15, if it is determined that the wake-up source is not IGN, that is, the wake-up source is the vehicle control signal;

[0099] S19. Control the MCU to enter the RTC periodic wake-up mode, thereby periodically waking up the MCU through a preset wake-up period;

[0100] S20, autonomous vehicles enter hibernation mode.

[0101] In this embodiment of the disclosure, when the autonomous vehicle is in a powered-off state, it can be controlled to enter a working state or a dormant state based on the received ignition signal or vehicle control signal, thereby achieving flexible control of the autonomous vehicle.

[0102] Please refer to Figure 9 , Figure 9 This is the third flowchart of a control method for an autonomous vehicle provided in this disclosure embodiment, as shown below. Figure 9 As shown, when the autonomous vehicle is in operation, the method includes the following steps:

[0103] S21. Detect whether an ignition signal (IGN) has been received;

[0104] S22. If not, the DC-DC section in the power management module is powered down by the MCU, and the MPU in the automatic driving start module is put into standby mode by the MCU.

[0105] S23. Control the MCU to enter the RTC periodic wake-up mode, thereby periodically waking up the MCU through a preset wake-up period;

[0106] S24. Autonomous vehicles enter hibernation mode;

[0107] S25. In sleep mode, determine whether the number of MCU periodic wake-up cycles is greater than the preset number;

[0108] S29. If yes, control the autonomous vehicle to enter the shutdown state; if no, control the autonomous vehicle to remain in the dormant state.

[0109] Alternatively, when the autonomous vehicle is in operation, the method may further include the following steps:

[0110] S26. After detecting that the MCU has received a shutdown command, wait for IGN;

[0111] S27. Check if IGN has been received;

[0112] S28. If yes, proceed to step S26; otherwise, power off the PMIC and DC-DC in the power management module via the MCU.

[0113] S29. The autonomous vehicle enters the shutdown state.

[0114] In this embodiment of the disclosure, when the autonomous vehicle is in operation, it can enter the shutdown state according to the received shutdown command, or it can control the autonomous vehicle to enter the sleep state according to whether the ignition signal is received, and determine whether to control the autonomous vehicle to enter the shutdown state based on the judgment of the number of MCU wake-up cycles in the sleep state, thereby realizing flexible control of the autonomous vehicle.

[0115] Please refer to Figure 10 , Figure 10 This is the fourth flowchart of a control method for an autonomous vehicle provided in this disclosure, as shown in the following embodiment. Figure 10 As shown, when the autonomous vehicle is in a dormant state, the method may include the following steps:

[0116] S31. Determine whether the number of times the MCU is periodically woken up is greater than the preset number;

[0117] S32. If not, control the autonomous vehicle to remain in sleep mode; if yes, control the autonomous vehicle to enter shutdown mode.

[0118] Alternatively, when the autonomous vehicle is in a dormant state, the method may further include the following steps:

[0119] S33. Check if IGN or vehicle control signals are received;

[0120] S34. If not, control the autonomous vehicle to remain in sleep mode; if yes, wake up the MCU, start the MCU and collect the wake-up source (i.e., IGN or vehicle control signal).

[0121] S35. Check if IGN has been received;

[0122] S36. If not, control the autonomous vehicle to remain in sleep mode; if yes, control the autonomous vehicle to enter working mode.

[0123] In this embodiment of the disclosure, when the autonomous vehicle is in a dormant state, it can be controlled to enter a shutdown state based on the determination of the number of times the MCU is woken up in a cycle, so as to save energy consumption; or, it can be controlled to enter a working state based on whether IGN is received, so as to achieve rapid start-up of the autonomous vehicle.
