In order to improve the range, automobile manufacturers try their best to reduce the power consumption of each automobile electronic system. In order to reduce the power consumption, the automobile electronic system generally has two modes of sleep and work.

[0057] Embodiment one

[0058] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a wake-up system provided by an embodiment of the present application. As Figure 1 shown, the wake-up system can include a wake-up circuit 10 and a wireless communication module 20, the wake-up circuit 10 being connected with the wireless communication module 20;

[0059] The wireless communication module 20 is configured to send a first wake-up signal to the wake-up circuit 10 after receiving a remote wake-up signal sent by a terminal device.

[0060] The wake-up circuit 10 is configured to wake up a control module 30 when receiving the first wake-up signal sent by the wireless communication module 20.

[0061] The wireless communication module 20 can communicate wirelessly with a terminal device. The terminal device is a device that can communicate wirelessly. For example, a mobile phone and the like. When the wireless communication module 20 receives a short message sent by the terminal device or an incoming call initiated by the terminal device, the wireless communication module 20 sends a first wake-up signal to the wake-up circuit 10. When the wake-up circuit 10 receives the first wake-up signal sent by the wireless communication module 20, the wake-up control module 30 is awakened, thereby realizing the function of remote wake-up and improving the reliability of wake-up.

[0062] For example, the wireless communication module 20 can be a 5G wireless communication module 20.

[0063] In the embodiment of the present application, when the wireless communication module 20 receives a remote wake-up signal, a first wake-up signal is sent to the wake-up circuit 10, triggering the wake-up circuit 10 to wake up the control module 30, thereby realizing remote wake-up of the control module 30 and improving the reliability of wake-up.

[0080] In the embodiment of the present application, when the first wake-up sub-circuit 12 receives the first wake-up signal sent by the wireless communication module 20, the switch sub-circuit 11 is turned on, so that the battery 40 is connected to the first power module 50, so that the first power module 50 is powered on.

[0081] Example 4

[0082] See also Figure 4 , Figure 4 This is a structural diagram of another wake-up system provided in an embodiment of the present application. Figure 4 is Figure 3 Further obtained on the basis of Figure 4 As shown, the first wake-up sub-circuit 12 includes a first diode D1, the anode of the first diode D1 is connected to the third end of the switch sub-circuit 11, and the cathode of the first diode D1 is used to connect to the wireless communication module 20;

[0083] The first wake-up signal is a low-level signal.

[0084] In an embodiment of the present application, the first wake-up signal is a low-level signal, which can pull down the third end of the switch sub-circuit 11, thereby turning on the switch sub-circuit 11, so that the battery 40 is connected to the first power module 50, so that the first power module 50 is powered on.

If the voltage of the positive electrode of the battery 40 is VBAT, the voltage U1 of the third end of the first switch tube Q1 is R2*VBAT / (R1+R2). The resistance values of the first resistor R1 and the second resistor R2 can be designed to make the voltage of the third end of the first switch tube Q1 satisfy the high level, so that the first switch tube Q1 is turned on.

[0106] The control module 30 outputs the wake-up maintenance signal to the wake-up maintenance sub-circuit in the case that the wireless communication module 20 outputs the first wake-up signal, or in the case that the power supply 70 of the vehicle outputs a second wake-up signal, or in the case that the signal of the signal port of the CAN communication module 80 is a third preset signal.

The resistance values of the third resistor R3 and the fourth resistor R4 can be designed to make the voltage of the third end of the second switch tube Q2 meet the high level.

After the whole vehicle is powered off, the first power supply module 50 is powered off, at this time the wake-up circuit 10 can be remotely woken up through the wireless communication module 20, thereby making the first power supply module 50 powered on.

[0117] After the whole vehicle is powered off, the power-on power supply 70 is closed, the output end ACC of the power-on power supply 70 outputs a low-level signal, the third diode D3 is cut off, and in the case where the first switch tube Q1 is disconnected, the enable end of the first power supply module 50 is low level, and the first power supply module 50 is powered off.

[0118] Optionally, as shown in the figure, in the case where the CAN communication module 80 is not woken up, the signal of the receiving end of the CAN communication module 80 is a high-level signal. Figure 4

[0119] In the embodiment of the application, in the case where the CAN communication module 80 does not receive message data, the CAN communication module 80 is not woken up, the receiving end of the CAN communication module 80 is a high-level signal, so as to make the fourth diode D4 cut off, the positive electrode VBAT of the battery 40, the first biasing module 111 and the fourth diode D4 do not form a loop, the voltage of the voltage division node of the first biasing module 111 is a low-level voltage, that is, the voltage of the third end of the first switch tube Q1 is a low-level voltage, so that the first switch tube Q1 is disconnected.

[0120] In the embodiment of the application, in the case where the wireless communication module 20 is woken up, the output end of the wireless communication module 20 outputs a low-level signal, so as to make the first switch tube Q1 conduct, and make the first power supply module 50 power on.

[0121] In the case where the first power supply module 50 is powered on, the output end of the control module 30 outputs a high-level signal, so as to make the second switch tube Q2 conduct.

[0122] ​​In the embodiment of the present application, when the control module 30 is in the sleep mode, if the first switch tube Q1 is turned on, the enable end of the first power module 50 is a high-level signal, the wake-up module is woken up, the first power module 50 is powered on, the control module 30 enters the working mode, and the output end of the control module 30 outputs a high-level signal to make the second switch tube Q2 conduct, thereby keeping the first switch tube Q1 continuously conduct. When the control module 30 is in the working mode, if the first switch tube Q1 is turned off, the enable end of the first power module 50 is a low-level signal, the wake-up module is not woken up, the first power module 50 is powered off, the control module 30 enters the sleep mode, and the output end of the control module 30 outputs a low-level signal.

[0123] When the enable end of the first power module 50 is a high-level signal, the first power module 50 is powered on, and when the enable end of the first power module 50 is a low-level signal, the first power module 50 is powered off.

[0124] The first switch tube Q1 and the second switch tube Q2 are high-level conductive switch tubes.

[0125] In an optional embodiment, the first switch tube Q1 and the second switch tube Q2 can be one of a field effect tube and a triode. The field effect tube can include a metal-oxide-semiconductor field-effect transistor (MOSFET), which can be referred to as a MOS tube for short. Exemplarily, Figure 4 The first switch tube Q1 in the embodiment is a P-type MOS tube, the first end of the first switch tube Q1 is the drain of the P-type MOS tube, the second end of the first switch tube Q1 is the source of the P-type MOS tube, and the third end of the first switch tube Q1 is the gate of the P-type MOS tube. The diode between the source and the drain of the P-type MOS tube is the body diode of the P-type MOS tube. The P-type MOS tube can also be referred to as a P-channel MOS tube (abbreviated as PMOS). Exemplarily, Figure 4 The second switch tube Q2 in the embodiment is an NPN-type triode, the first end of the second switch tube Q2 is the collector of the NPN-type triode, the second end of the second switch tube Q2 is the emitter of the NPN-type triode, and the third end of the second switch tube Q2 is the base of the NPN-type triode.

[0126] When the output end of the wireless communication module 20 outputs a low-level signal, the first diode D1 is turned on, the positive pole VBAT of the battery 40, the first bias module 111, and the first diode D1 form a loop, and the voltage at the third end of the first switch tube Q1 is a high-level voltage, so that the first switch tube Q1 is turned on.

[0127] When the output end of the wireless communication module 20 outputs a high-level signal, the first diode D1 is cut off, the positive pole VBAT of the battery 40, the first bias module 111 and the first diode D1 do not form a loop, and the voltage at the third end of the first switch tube Q1 is a low-level voltage, so that the first switch tube Q1 is turned off.

[0128] When the wireless communication module 20 receives a short message or a call from a terminal device, the wireless communication module 20 can enter a working mode. If the wireless communication module 20 does not receive a short message or a call for more than a continuous set time, the wireless communication module 20 also enters a sleep mode in order to save power consumption. It can be seen that the first power module 50 is powered on by the wake-up circuit 10 after the wireless communication module 20 normally works, and the continuous power-on of the first power module 50 cannot be guaranteed. As shown in the figure, after the first power module 50 is powered on, the output end of the control module 30 outputs a high-level signal to turn on the second switch tube Q2. After the wireless communication module 20 enters the working mode, even if the wireless communication module 20 enters the sleep mode again, when the control module 30 enters the working mode, the control module 30 can control the continuous power-on of the first power module 50. Figure 5

[0129] Whether the control module 30 enters the sleep mode can be determined according to whether the whole vehicle is powered on. In the case that the whole vehicle is powered off, the first power module 50 is powered off, and the control module 30 can enter the sleep mode. In the case that the whole vehicle is powered on, the first power module 50 is powered on, and the control module 30 can enter the working mode.

[0130] The wireless communication module 20 can be a 5G wireless communication module 20. For example, the wireless communication module 20 can be an AG59xE module.

[0131] In an optional embodiment, the control module 30 can be a microcontroller unit (MCU). For example, the output end of the control module 30 can be an MCU_HOST pin, and the signal output by the MCU_HOST pin is an MCU_HOST signal. When the first power module 50 is powered on, the MCU_HOST pin of the MCU outputs the MCU_HOST signal as a high-level signal, and when the first power module 50 is powered off, the MCU_HOST pin of the MCU outputs the MCU_HOST signal as a low-level signal.

[0132] ​The output end of the control module 30 outputs a high level signal to complete the closed loop control. When the whole vehicle is powered off, the control module 30 enters the sleep mode by turning off the first power module 50. After the control module 30 enters the sleep mode, the output end of the control module 30 outputs a low level signal. After the control module 30 enters the working mode, the output end of the control module 30 outputs a high level signal.

[0133] The wake-up circuit 10 of the embodiment of the application simplifies the software control and improves the anti-interference capability.

[0134] The first bias module 111 can include at least two resistors in series. The second bias module 151 can include at least two resistors in series.

The external wake-up sources in the antenna include a low-level effective CAN wake-up source and an RI wake-up source and a high-level effective ACC wake-up source. When the control module 30 detects that the peripherals and the load are disconnected and the whole vehicle is powered off to reach the sleep condition, the MCU_HOST pin connected to the wake-up circuit 10 changes from high level to low level, the first switch tube Q1 of the wake-up circuit 10 is not conductive, the first power module 50 is powered off, the control module 30 does not work, and the antenna terminal enters the sleep mode. When the level state of the external wake-up source changes, the first switch tube Q1 of the wake-up circuit 10 is conductive, the first power module 50 is powered on, the control module 30 is powered on to work, and the MCU_HOST pin connected to the wake-up circuit 10 is set from low level to high level, so as to maintain the first switch tube Q1 of the wake-up circuit 10 conductive, thereby realizing the wake-up of the antenna terminal.
