Further, the main control module 130 may further include, but is not limited to, a plurality of output communication pins, and the plurality of output communication pins may be electrically connected to the power management module 120 and the power supply module 110, respectively, for outputting a control signal to the power management module 120 and controlling a circuit between the power supply module 110 and the main control module 130 to realize periodic conduction.

For example, referring to fig. 1, the main control module 130 may be provided with a first output communication pin (SCR-GPO 1) and a second output communication pin (SCR-GPO 2). The first output communication pin (SCR-GPO 1) may be electrically connected to a Wake pin in the power management module 120, so as to output a Wake instruction to the Wake pin, and control a level change of the Wake pin in the power management module 120. The second output communication pin (SCR-GPO 2) may be electrically connected to a circuit between the power supply module 110 and the plurality of input communication pins of the main control module 130, so as to control periodic conduction of the circuit between the power supply module 110 and the main control module 130 when the vehicle-mounted multi-wake-up source controller 100 is in the sleep mode, thereby reducing static power consumption of the vehicle-mounted multi-wake-up source controller 100.

It should be further noted that, the main control module 130 and the power management module 120 may be electrically connected through other communication pins. For example, referring to fig. 1, the power management module 120 and the main control module 130 may further include a data output pin (MASTER IN SLAVE Out, MISO), a data input pin (Master Out Slave In, MOSI), a Clock signal pin (SClk), and a chip select signal pin (CHIP SELECT, CS), respectively.

Referring to fig. 1, the vehicle-mounted multi-wake-up source controller 100 may further include at least one circuit control element 140, and the circuit control element 140 may be electrically connected to the power supply module 110 and the main control module 130, respectively, so as to perform periodic conduction processing on a circuit between the power supply module 110 and the main control module 130 under the control of the main control module 130, thereby reducing the static power consumption of the vehicle-mounted multi-wake-up source controller 100.

For example, referring to fig. 1, when the vehicle-mounted multi-wake-up source controller 100 is in the sleep mode, the main control module 130 enters the low power consumption state, and the main control module 130 can control the period of the circuit control element 140 in the off state to be 100 ms through the second output communication pin (SCR-GPO 2) to control the circuit between the power supply module 110 and the main control module 130 to be in the off state, so as to reduce the static power consumption during the whole vehicle sleep. However, the period in which the circuit control element 140 is turned off may be 150 ms, the period in which the circuit control element 140 is turned off may be 200 ms, or other values may be set as long as it is ensured that the circuit control element 140 is always turned on when the external switch is pressed. In addition, the period of the main control module 130 controlling the circuit control element 140 to be in the on state may be 100 seconds, or may be 300 seconds, or may be 400 seconds or other values. The circuit control element 140 may be provided with one or two or other number. That is, as long as the circuit control element 140 is provided with at least one.

Further, the circuit control element 140 may be a triode, but not limited thereto, and the circuit control element 140 may be other types of circuit components. When the circuit control element 140 is only provided with one and is a PNP transistor, the emitter end of the transistor may be electrically connected to the power supply module 110, the base end may be electrically connected to the output communication pin of the main control module 130, one side of the collector end is electrically connected to a plurality of different input communication pins, and the other side of the collector end is electrically connected to a plurality of external switches corresponding to the input communication pins. In addition, at least one resistor unit may be disposed on the circuit between the circuit control element 140 and the output communication pins, and at least one resistor unit is disposed on the circuit between the circuit control element 140 and each input communication pin, so as to prevent the circuit between the circuit control element 140 and the main control module 130 from being shorted.

For example, referring to fig. 1, in an embodiment of the invention, when only one circuit control element 140 is provided, the circuit control element 140 is a first transistor (T1), and the first transistor (T1) is a PNP transistor, the transmitting terminal of the first transistor (T1) may be electrically connected to the power supply module 110.

Further, the base end of the first triode (T1) may be electrically connected to the second output communication pin (SCR-GPO 2) of the main control module 130, and one side of the collector end of the first triode (T1) may be electrically connected to the first input communication pin, the second input communication pin, the third input communication pin and the fourth input communication pin of the main control module 130, respectively.

Further, the other side of the collector terminal of the first triode (T1) may be electrically connected to the first external switch, the second external switch, the third external switch and the fourth external switch, respectively. The first external switch can be electrically connected to the first input communication pin, the second external switch can be electrically connected to the second input communication pin, the third external switch can be electrically connected to the third input communication pin, and the fourth external switch can be electrically connected to the fourth input communication pin.

Furthermore, a resistor unit R1 may be provided in the circuit between the first transistor (T1) and the second output communication pin (SCR-GPO 2). Two resistor units R2 and R6 can be connected in series on the circuit between the first triode (T1) and the first input communication pin. Two resistor units R3 and R7 can be connected in series on the circuit between the first triode (T1) and the second input communication pin. The circuit of the first triode (T1) communicated with the third input communication pin can be connected with two resistor units R4 and R8 in series. The circuit of the first triode (T1) communicated with the fourth input communication pin can be connected with two resistor units R5 and R9 in series. The resistor units R2, R3, R4, and R5 may be disposed on a side close to the transistor, and the resistor units R6, R7, R8, and R9 may be disposed on a side close to the main control module 130.

Referring to fig. 2, in another embodiment of the present invention, when two circuit control elements 140 are provided, the two circuit control elements 140 may be a first transistor (T1) and a second transistor (T2), the first transistor (T1) is a PNP transistor, and the second transistor (T2) is an NPN transistor, the second transistor may be disposed between the first transistor and the main control module 130, and the second transistor is electrically connected to the first transistor and the main control module 130, respectively.

Referring to fig. 2, specifically, the base end of the second triode may be electrically connected to a second output communication pin (SCR-GPO 2) of the main control module 130. The current collecting end of the second triode can be electrically connected to the base end of the first triode, and the emitting end of the second triode can be grounded. In addition, in order to avoid short circuit between the first triode and the second triode, a resistor unit R10 may be connected in series between the base end of the first triode and the collector end of the second triode.

Referring to fig. 1 and fig. 2, in an embodiment of the invention, when the main control module 130 detects that the level of the input communication pin changes due to the operation of the corresponding external switch, the action performed by the main control module is to send a wake-up instruction to the power management module 120. However, the main control module 130 may also generate corresponding product execution instructions when detecting that the level of the input communication pin changes due to the operation of the corresponding external switch. When the main control module 130 determines that the sleep instruction is received, the action it performs may be to send a power consumption switching instruction to the power management module 120.

Further, when the power management module 120 determines that the wake-up instruction sent by the main control module 130 is received, the power management module 120 performs the normal power supply process on the main control module 130, and generates a wake-up termination signal. When the main control module 130 determines that the wake-up termination signal is detected, it determines that the power management module 120 is wake-up successfully. In addition, when the power management module 120 determines that the power consumption switching instruction sent by the main control module 130 is received, the action performed by the power management module 120 may be to perform the sleep power-off process on the main control module 130, and generate a sleep termination signal. When the main control module 130 determines that the sleep termination signal is detected, it determines that the sleep of the power management module 120 is successful.

For example, referring to fig. 1, in an embodiment of the invention, one circuit control element 140 is provided, and the circuit control element 140 is a first transistor (T1). Four input communication pins may be disposed on the main control module 130, and each input communication pin is correspondingly and electrically connected to an external switch. The connection mode of the first triode and the four input communication pins and the number of the resistor units arranged on the circuit between the first triode and the input communication pins can be the same as the embodiment. One end of the external switch may be electrically connected to the input communication pin, and the other end thereof may be grounded. The first external switch is a wiper switch, the second external switch is a turn signal switch, the third external switch is a high beam switch, and the fourth external switch is a low beam switch.

Specifically, when the wiper blade needs to be opened, the first external switch can be manually pressed to lower the level of the first input communication pin electrically connected with the first external switch.

When the master control module 130 detects that the level of the first input communication pin is pulled down, the action performed by the master control module is to send a Wake-up instruction to the Wake pin of the power management module 120 through the first output communication pin, so as to pull down the level of the Wake pin of the power management module 120.

However, the main control module 130 generates a corresponding product execution instruction when it detects that the level of the first input communication pin is pulled down, and the product execution instruction is a wiper opening instruction. When the power management module 120 detects that the level of the Wake pin is pulled down, that is, it is determined that a Wake command is received, the power management module 120 resumes the normal power mode, performs normal power supply processing on the main control module 130, and generates a Wake termination signal. When the master control module 130 detects that the wake-up termination signal is generated on the INT pin of the power management module 120 through the fifth input communication pin, it is determined that the wake-up of the power management module 120 is successful, and the generated wiper opening instruction is issued to the wiper controller, so that the wiper controller executes the wiper opening instruction.

Similarly, when the turn signal of the automobile needs to be turned on, the turn signal can be turned on by manually pressing the second external switch. When the high beam of the automobile needs to be started, the high beam can be started by manually pressing the third external switch. When the dipped headlight of the automobile needs to be started, the dipped headlight can be started by manually pressing the fourth external switch. Therefore, a plurality of different external switches are arranged to be respectively and electrically connected with a plurality of different input communication pins of the main control module 130, so that accurate identification of a plurality of vehicle-mounted signal sources can be realized, and signal delay is reduced.

Referring to fig. 1 and fig. 3, the present invention further provides an automobile, where the automobile 200 may include the above-mentioned vehicle-mounted multi-wake-up source controller 100, and the vehicle-mounted multi-wake-up source controller 100 is provided with at least one to achieve accurate wake-up of multiple signal sources of the automobile 200 and improve response speed of the signal sources, and further, by setting the vehicle-mounted multi-wake-up source controller 100, static power consumption during whole automobile dormancy can be reduced, and static energy saving is achieved.

Referring to fig. 1, in an embodiment of the present invention, an automobile power source may be selected as the power supply module 110, and a diode (D1) 111 may be disposed at an output end side of the power supply module 110. A power management module 120 and a main control module 130 are respectively disposed, and the output ends of the diodes (D1) 111 can be respectively electrically connected to the input end of the power management module 120 and the main control module 130, so as to convert the ac into the pulse dc with a single direction, so as to supply power to the power management module 120 and the main control module 130.

When the power management module 120 is awakened and in a normal operating state, the three power output ports of the power management module 120 can normally supply power to the main control module 130. When the power management module 120 is in a low power consumption state, only the main power rail between the power management module 120 and the main control module 130 can normally supply power.

Further, a data output pin (MASTER IN SLAVE Out, MISO), a data input pin (Master Out Slave In, MOSI), a Clock signal pin (SClk), and a chip select signal pin (CHIP SELECT, CS) corresponding to the power management module 120 may also be provided on the main control module 130. The data output pin, the data input pin, the clock signal pin and the chip select signal pin in the main control module 130 are electrically connected to the corresponding data output pin, data input pin, clock signal pin and chip select signal pin in the power management module 120, respectively.

Further, the main control module 130 may further be provided with five input communication pins and two output communication pins. Four input communication pins in the main control module 130 may be electrically connected to the power supply module 110, respectively, and four different input communication pins may be electrically connected to four different external switches. The four different external switches are respectively a wiper switch, a steering lamp switch, a high beam lamp switch and a low beam lamp switch.

Specifically, the main control module 130 may be provided with a first input communication pin (SCR-GPI 1), a second input communication pin (SCR-GPI 2), a third input communication pin (SCR-GPI 3), a fourth input communication pin (SCR-GPI 4), and a fifth input communication pin (SCR-GPI 5), respectively.

It should be further noted that the output communication pins of the main control module 130 may be a first output communication pin (SCR-GPO 1) and a second output communication pin (SCR-GPO 2), respectively. The first output communication pin (SCR-GPO 1) may be electrically connected to a Wake pin in the power management module 120, so as to output a Wake instruction to the Wake pin, and control a level change of the Wake pin in the power management module 120.

Further, a circuit control element 140 is further disposed between the power supply module 110 and the main control module 130, and the circuit control element 140 is electrically connected to the output end of the diode (D1) 111 and the second output communication pin (SCR-GPO 2) of the main control module 130, respectively, so as to realize the periodic conduction of the main control module 130 under the periodic control of the main control module. The circuit control element 140 is a first triode (T1) which is a PNP triode. When the vehicle-mounted multi-wake-up source controller 100 is in the sleep mode, the main control module 130 is in a low power consumption state, and the period of the second output communication pin (SCR-GPO 2) for controlling the circuit control element 140 to be in the off state by the main control module 130 is 100 milliseconds, so as to control the circuit between the power supply module 110 and the main control module 130 to be in the off state in the period of 100 milliseconds, thereby reducing the static power consumption of the whole vehicle.

Specifically, the transmitting end of the first triode is electrically connected to the output end of the diode (D1) 111, the base end is electrically connected to the second output communication pin (SCR-GPO 2) of the main control module 130, one side of the collecting end is electrically connected to the first input communication pin, the second input communication pin, the third input communication pin and the fourth input communication pin, and the other side of the collecting end is electrically connected to the first external switch, the second external switch, the third external switch and the fourth external switch, respectively.

In addition, a resistor unit R1 is connected in series to the circuit between the first transistor and the second output communication pin (SCR-GPO 2) to prevent the circuit between the first transistor and the second output communication pin (SCR-GPO 2) from being shorted. It is also necessary to connect two resistor units R2 and R6 in series in the circuit between the first transistor (T1) and the first input communication pin. Two resistor units R3 and R7 need to be connected in series in the circuit between the first transistor (T1) and the second input communication pin. It is also necessary to connect two resistor units R4 and R8 in series on the circuit where the first transistor (T1) communicates with the third input communication pin. It is also necessary to connect two resistor units R5 and R9 in series to a circuit in which the first transistor (T1) is connected to the fourth input communication pin, so as to prevent a short circuit from occurring between the first transistor and the input communication pin of the main control module 130.

Referring to fig. 1, in this embodiment, the switching of the vehicle-mounted multi-wake-up source controller 100 from the sleep mode to the wake-up mode will be described as an example. When the vehicle-mounted multi-wake-up source controller 100 is in the sleep mode, the power management module 120 and the main control module 130 are both in a low power consumption state, and the power management module 120 supplies power to the main control module 130 only through the main power rail.

When the signal source of the wiper on the automobile needs to be awakened, the first external switch can be manually pressed to pull down the level of the first input communication pin on the main control module 130. Since the main control module 130 controls the period of the first transistor (T1) in the off state to be 100 ms through the second output communication pin (SCR-GPO 2) and the time for manually pressing the first external switch is greater than 100 ms, when the first external switch is pressed, the circuit between the first transistor and the first input communication pin is in the on state, and the level of the first input communication pin is pulled down. When the master control module 130 detects that the level of the first input communication pin is pulled down, the action performed by the master control module is to send a Wake-up instruction to the Wake pin of the power management module 120 through the first output communication pin, so as to pull down the level of the Wake pin of the power management module 120.

Further, when the main control module 130 detects that the level of the first input communication pin is pulled down, it also generates a corresponding product execution instruction, and the product execution instruction is a wiper opening instruction. When the power management module 120 detects that the level of the Wake pin is pulled down, that is, it is determined that a Wake command is received, the power management module 120 switches from the low power mode to the Wake mode, and performs normal power supply processing on the main control module 130 by using the main power rail and the two auxiliary power rails, and generates a Wake termination signal. When the main control module 130 detects that the wake-up termination signal is generated on the INT pin of the power management module 120 through the fifth input communication pin, it may be determined that the power management module 120 is successfully waken up, so that the main control module 130 may issue the generated wiper opening instruction to an external wiper controller, so that the wiper controller may execute the wiper opening instruction.

Similarly, when the turn signal source of the automobile needs to be awakened, the second external switch can be manually pressed to realize the awakening of the turn signal source. When the high beam signal source of the automobile needs to be awakened, the third external switch can be manually pressed to realize the awakening of the high beam signal source. When the low beam light signal source of the automobile needs to be awakened, the low beam light signal source can be awakened by manually pressing the fourth external switch. Therefore, a plurality of different external switches can be arranged to be respectively and electrically connected with a plurality of different input communication pins of the main control module 130, so that accurate identification of a plurality of vehicle-mounted signal sources is realized, and meanwhile, due to the direct connection between the power supply module 110 and the main control module 130, preferential pre-awakening of the main control module 130 can be realized, so that signal delay is reduced.

Referring to fig. 1, in this embodiment, the switching of the vehicle-mounted multi-wake-up source controller 100 from the wake-up mode to the sleep mode may also be described as an example. When a lock key in the bluetooth key is pressed, the main control module 130 may receive a sleep command of the whole vehicle, and process the sleep command to send a power consumption switching command to the power management module 120 through a data output pin (MASTER IN SLAVE Out, MISO), a Clock signal pin (SClk), and a chip select signal pin (CHIP SELECT, CS). When the power management module 120 determines that the power consumption switching instruction is received, the action performed by the power management module may be to perform a sleep power-off process on the main control module 130, and generate a sleep termination signal.

Specifically, the power-off processing for the main control module 130 may be that the power management module 120 supplies power only through the main power rail between the first power output port of the power management module 120 and the first power input port of the main control module 130, and other power supply circuits between the power management module 120 and the main control module 130 are in a power-off state.

Further, after the sleep power-off process of the power management module 120 on the main control module 130 is completed, the INT pin of the power management module 120 may generate a sleep termination signal and send the sleep termination signal to the fifth input communication pin (SCR-GPI 5) of the main control module 130. When the fifth input communication pin (SCR-GPI 5) of the main control module 130 determines that the sleep termination signal is detected, it is determined that the sleep of the power management module 120 is successful, and the external product is controlled to enter the sleep mode.

Referring to fig. 2, in another embodiment of the present invention, two circuit control elements 140 may be disposed in the vehicle-mounted multi-wake-up source controller 100, and the connection relationship between the power supply module 110, the power management module 120 and the main control module 130 may be set according to the above embodiments. The two circuit control elements 140 may be a first triode (T1) and a second triode (T2), respectively, where the first triode (T1) is a PNP triode and the second triode (T2) is an NPN triode.

Specifically, the base end of the second triode is electrically connected to a second output communication pin (SCR-GPO 2), the collector end of the second triode is electrically connected to the base end of the first triode, and the emitting end of the second triode can be grounded. In addition, in order to avoid short circuit between the first triode and the second triode, a resistor unit R10 may be connected in series between the base end of the first triode and the collector end of the second triode. In order to avoid a short circuit between the second triode and the second output communication pin (SCR-GPO 2), a resistor unit R1 may be connected in series between the second triode and the second output communication pin (SCR-GPO 2).

Further, the transmitting end of the first triode is electrically connected to the output end of the diode (D1) 111, one side of the collecting end is electrically connected to the first input communication pin, the second input communication pin, the third input communication pin and the fourth input communication pin, and the other side of the collecting end is electrically connected to the first external switch, the second external switch, the third external switch and the fourth external switch, respectively. The first external switch may be a bluetooth key switch, and the first external switch may be a relay switch, and the corresponding external execution unit may be a door handle lock. The second external switch may be a wiper switch and the second external switch is a manual switch. The third external switch may be a turn signal switch and the fourth external switch may be a high beam switch.

Further, when the vehicle-mounted multi-wake-up source controller 100 is in the sleep mode, in order to reduce the static power consumption of the whole vehicle, the main control module 130 may perform periodic pull-up response processing on the potential of the second triode (T2) through the second output communication pin (SCR-GPO 2) output control signal, and the period of the pull-up response is 100 ms, so that the circuit between the first triode and the second triode is in the open circuit state, thereby reducing the current in the main control module 130 and the resistor units R1 and R10, and further reducing the static power consumption of the vehicle-mounted multi-wake-up source controller.

Referring to fig. 2, in another embodiment of the present invention, the switching of the vehicle-mounted multi-wake-up source controller 100 from the sleep mode to the wake-up mode is illustrated. When the vehicle-mounted multi-wake-up source controller 100 is in the sleep mode, the power management module 120 and the main control module 130 are both in the low power consumption mode, and the power management module 120 supplies power to the main control module 130 only through the main power rail. The main control module 130 may output a control signal through a second output communication pin (SCR-GPO 2) to perform periodic pull-up response processing on the potential of the second triode (T2), where the period of the pull-up response is 100 ms.

When the door handle lock on the automobile needs to be unlocked, the unlocking key in the Bluetooth key can be pressed to close the first external switch on the on-board multi-wake-up source controller 100. When the first external switch is closed, the level of the first input communication pin on the main control module 130 may be pulled down. When the master control module 130 detects that the level of the first input communication pin is pulled down, the action performed by the master control module is to send a Wake-up instruction to the Wake pin of the power management module 120 through the first output communication pin, so as to pull down the level of the Wake pin of the power management module 120.

Further, when the main control module 130 detects that the level of the first input communication pin is pulled down, it also generates a corresponding product execution instruction, and the product execution instruction is a door handle unlocking instruction. When the power management module 120 detects that the level of the Wake pin is pulled down, that is, it is determined that a Wake instruction is received, the power management module 120 switches from the low power consumption mode to the normal power supply mode, and performs normal power supply processing on the main control module 130 by using the main power rail and the two auxiliary power rails, so as to generate a Wake termination signal and send the Wake termination signal to the fifth input communication pin. When the main control module 130 detects that the wake-up termination signal is generated on the INT pin of the power management module 120 through the fifth input communication pin, it may be determined that the power management module 120 is successfully waken up, so that the main control module 130 may issue the generated door handle unlocking command to an external door handle controller, so that the door handle controller may execute the door handle unlocking command.
