[0042] To clarify the technical solution of this disclosure, the disclosure is illustrated through the following specific embodiments. However, it is not limited to these specific embodiments, and the features in each embodiment can be arbitrarily combined or replaced.

[0043] In an optional implementation, the door lock control system provided in this disclosure is used to connect to the line between the power module 30 and the door lock module 40.

This door lock control system controls the first switch unit 201 to close or the second switch unit 202 to close, so that the line between the power module 30 and the door lock module 40 is connected, thereby enabling the door to unlock normally even if the battery system fails, ensuring vehicle safety.

[0044] In specific implementation methods, such as Figures 1-13 As shown, the switch module 20 includes a first switch unit 201 and a second switch unit 202. The first switch unit 201 is a discharge MOSFET, and the second switch unit 202 is also a discharge MOSFET. The control module 10 includes a first control unit 101 and / or a second control unit 102. The control module 10 and the switch module 20 are electrically connected. The first control unit 101 is used to control the first switch unit 201 to close and control the second switch unit 202 to open, so that when the battery system is normal, the door can be unlocked normally through the first switch unit 201. Alternatively, the first control unit 101 is used to control the second switch unit 202 to close and control the first switch unit 202 to open. Unit 201 is disconnected so that the door can be unlocked normally via the second switch unit 202 when the battery system fails; the second control unit 102 is used to control the first switch unit 201 to close and the second switch unit 202 to open so that the door can be unlocked normally via the first switch unit 201 when the battery system is normal; or, the second control unit 102 is used to control the second switch unit 202 to close and the first switch unit 201 to open so that the door can be unlocked normally via the second switch unit 202 when the battery system fails. The control module 10 can ensure that the door can be unlocked normally under any circumstances.

When the first switch unit 201 is open, the control module 10 can control the second switch unit 202 to close, so that the door can be unlocked normally; when the second switch unit 202 is open, the control module 10 can control the first switch unit 201 to close, so that the door can be unlocked normally. That is, the parallel connection of the first switch unit 201 and the second switch unit 202 ensures that the door can be unlocked normally under any circumstances.

[0046] In specific implementation methods, such as Figure 1 , 2 As shown in Figure 3, the first switch unit 201 and the second switch unit 202 are connected in parallel. One end of the control module 10 is electrically connected to the first switch unit 201, and the other end of the control module 10 is electrically connected to the second switch unit 202. The first end of the first switch unit 201 is electrically connected to the power module 30, the second end of the first switch unit 201 is electrically connected to the door lock module 40, and the third end of the first switch unit 201 is electrically connected to the control module 10.

The parallel connection of the first switch unit 201 and the second switch unit 202 ensures that the control module 10 controls the second switch unit 202 to close when the first switch unit 201 is open, and controls the first switch unit 201 to close when the second switch unit 202 is open. This ensures that either the first switch unit 201 or the second switch unit 202 will always close normally, thus guaranteeing that the car door can be unlocked normally.

[0047] In one optional implementation, one end of the control module 10 is electrically connected to the first switch unit 201, and the other end of the control module 10 is electrically connected to the second switch unit 202. The control module 10 is electrically connected to both the first switch unit 201 and the second switch unit 202 simultaneously, which enables more precise control over the opening and closing of the first switch unit 201 and the second switch unit 202.

[0048] In specific implementation methods, such as Figure 1 , 2As shown in Figures 3, 4, and 5, the control module 10 includes a first control unit 101 and / or a second control unit 102.

One end of the first control unit 101 is electrically connected to the first switch unit 201, and the other end of the first control unit 101 is electrically connected to the second switch unit 202. One end of the second control unit 102 is electrically connected to the first switch unit 201, and the other end of the second control unit 102 is electrically connected to the second switch unit 202. The first control unit 101 is used to control the first switch unit 201 to close and control the second switch unit 202 to open, so that when the battery system is normal, the door can be unlocked normally through the first switch unit 201. Alternatively, the first control unit 101 is used to control the second switch unit 202 to close and control the first switch unit 202 to open.

The control module 10 is electrically connected to both the first switch unit 201 and the second switch unit 202 so that the control unit can control both the first switch unit 201 and the second switch unit 202, thereby ensuring that the door can be unlocked under any circumstances.

[0049] In one optional implementation, the control module 10 includes a first control unit 101, which controls the first switch unit 201 to close and the second switch unit 202 to open; or, the first control unit 101 controls the second switch unit 202 to close and the first switch unit 201 to open. The first control unit 101 can control the first switch unit 201 to close or control the second switch unit 202 to close, and must simultaneously ensure that the second switch unit 202 is open when the first switch unit 201 is closed and the first switch unit 201 is open when the second switch unit 202 is closed. The first control unit 101 facilitates the door lock control system to control the closing of either switch unit, thereby ensuring that the door can be unlocked.

[0050] In specific implementation methods, such as Figure 1 , 2As shown in Figures 3 and 4, the control module 10 includes a first control unit 101, which may be a BMS controller. The first terminal of the first control unit 101 is electrically connected to the first switch unit 201, and the second terminal of the first control unit 101 is electrically connected to the second switch unit 202. The first control unit 101 is used to control the first switch unit 201 to close and control the second switch unit 202 to open, so that the door can be unlocked normally through the first switch unit 201 when the battery system is normal. Alternatively, the first control unit 101 is used to control the second switch unit 202 to close and control the first switch unit 201 to open, so that the door can be unlocked normally through the second switch unit 202 when the battery system malfunctions. The first control unit 101 can ensure that the door can be unlocked under any circumstances, thereby improving driving safety.

[0051] In an optional implementation, the control module 10 further includes a second control unit 102, which is used to control the first switch unit 201 to close and control the second switch unit 202 to open; or, the second control unit 102 is used to control the second switch unit 202 to close and control the first switch unit 201 to open. The second control unit 102 can control the first switch unit 201 to close or control the second switch unit 202 to close, and must simultaneously ensure that the second switch unit 202 is open when the first switch unit 201 is closed and the first switch unit 201 is open when the second switch unit 202 is closed. The second control unit 102 facilitates the door lock control system to control the closing of either switch unit, thereby ensuring that the door can be unlocked.

[0052] In specific implementation methods, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, the control module 10 also includes a second control unit 102. The second control unit 102 can be a mutual exclusion logic chip. The first terminal of the second control unit 102 is electrically connected to the first switch unit 201, and the second terminal of the second control unit 102 is electrically connected to the second switch unit 202. The second control unit 102 is used to control the first switch unit 201 to close and control the second switch unit 202 to open, so that the door can be unlocked normally through the first switch unit 201 when the battery system is normal. Alternatively, the second control unit 102 is used to control the second switch unit 202 to close and control the first switch unit 201 to open, so that the door can be unlocked normally through the second switch unit 202 when the battery system malfunctions. The second control unit 102 can ensure that the door can be unlocked under any circumstances, improving driving safety.

[0053] In one optional implementation, the control module 10 includes a first control unit 101 and a second control unit 102. The first control unit 101 is used to control the first switch unit 201 to close and the second switch unit 202 to open, and the second control unit 102 is used to control the second switch unit 202 to close and the first switch unit 201 to open; or, the first control unit 101 is used to control the second switch unit 202 to close and the first switch unit 201 to open, and the second control unit 102 is used to control the first switch unit 201 to close and the second switch unit 202 to open. The door lock control system has both the first control unit 101 and the second control unit 102. The redundant design of the first control unit 101 and the second control unit 102 can better ensure that either the first switch unit 201 or the second switch unit 202 will be closed under any circumstances so that the door can be unlocked.

[0054] In specific implementation methods, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, the control module 10 includes a first control unit 101 and a second control unit 102. The first control unit 101 can be a BMS controller, and the second control unit 102 can be a mutex logic chip. The first terminal of the first control unit 101 is electrically connected to the first switching unit 201, and the second terminal of the first control unit 101 is electrically connected to the second switching unit 202. The first terminal of the second control unit 102 is electrically connected to the first switching unit 201, and the second terminal of the second control unit 102 is electrically connected to the second switching unit 202. The first control unit 101 is used to control the first switching unit 201 to close and control the second switching unit 202 to open, and the second control unit 102 is used to control the second switching unit 202 to close. The first control module 101 controls the second control module 202 to close and the first control module 201 to open; or, the first control module 101 controls the second control module 202 to close and the first control module 201 to open, and the second control module 102 controls the first control module 201 to close and the second control module 202 to open. The first control module 101 and the second control module 102 coexist, which is a redundant design so that when the battery system is normal, either the first control module 10 or the second control module 10 can control the first control module 201 to close, and when the battery system fails, either the first control module 10 or the second control module 10 can control the second control module 202 to close. This better ensures that the door can be unlocked regardless of whether the battery system is normal or abnormal, thus improving safety.

[0055] In an optional implementation, the switch module 20 further includes a third switch unit 203. One end of the third switch unit 203 is electrically connected to the first control unit 101, and the other end of the third switch unit 203 is electrically connected to the first switch unit 201. The first switch unit 201 is a discharge switch, and the third switch unit 203 is a charging switch. When the battery system is normal, the current from the positive terminal of the power module 30 flows through the third switch unit 203 into the first switch unit 201, and finally into the door lock module 40, ensuring the normal conduction and operation of the circuit.

[0056] In specific implementation methods, such as Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, the switch module 20 also includes a third switch unit 203. The first end of the third switch unit 203 is electrically connected to the first control unit 101, the second end of the third switch unit 203 is electrically connected to the first switch unit 201, and the third end of the third switch unit 203 is electrically connected to the power module 30. The third switch unit 203 is a charging switch, and the first switch unit 201 is a discharging switch. The third switch unit 203 is a charging MOSFET, and the first switch unit 201 is a discharging MOSFET. When the battery system is working normally, the first control unit 101 controls the first switch unit 201 to close, thereby unlocking the door. At this time, current flows out from the positive terminal of the power supply, flows through the third switch unit 203 to the first switch unit 201, and then flows to the door lock module 40. The existence of the third switch can ensure that the door lock module 40 works normally when the battery system is working normally.

[0057] In an optional implementation, the control system further includes a voltage regulating module 50, which is electrically connected to the first switching unit 201. The voltage regulating module 50 is used to reduce the high voltage output by the power supply module 30 to a preset low voltage. The setting of the voltage regulating module 50 can significantly improve the voltage regulation accuracy and stability.

[0058] In specific implementation methods, such as Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, the control system also includes a voltage regulating module 50. One end of the voltage regulating module 50 is adapted to be electrically connected to the first switching unit 201, and the other end of the voltage regulating module 50 is adapted to be electrically connected to the door lock module 40. The voltage regulating module 50 is used to reduce the voltage output by the power supply module 30 to a preset low voltage. The power supply module 30 outputs a voltage of 48V. The high-voltage current flows out of the power supply module 30, flows into the first switching unit 201, and then flows into the voltage regulating module 50. After being reduced to the preset low voltage by the voltage regulating module 50, it is generally 12-24V. The 12-24V low voltage flows into the door lock module 40 to supply power to the door lock module 40. The voltage regulating module 50 can improve the efficiency of voltage conversion and facilitate the reduction of high voltage to a low voltage that can be used by the door lock module 40.

[0059] In an optional implementation, the control system further includes a signal receiving module 60, which is electrically connected to the first control unit 101. The signal receiving module 60 is used to receive external signals and input them into the first control unit 101. The configuration of the signal receiving module 60 facilitates the first control unit 101 to receive external abnormal signals.

[0060] In specific implementation methods, such as Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, the control system also includes a signal receiving module 60. The signal receiving module 60 is electrically connected to the first control unit 101. The signal receiving module 60 is used to receive external signals and input them into the first control unit 101. The external signals include at least one of a collision signal, a passenger compartment smoke alarm, and a vehicle alarm signal. After the first control unit 101 receives the above-mentioned abnormal external signal through the signal receiving module 60, it controls the second switch unit 202 to close and the first switch unit 201 to open. Current is supplied to the door lock module 40 through the second switch signal to ensure that the door lock module 40 can work normally and unlock the door.

[0061] In one optional implementation, the voltage regulating module 50 includes a DC-DC unit 501, one end of which is adapted to be electrically connected to the first switching unit 201, and the other end of which is adapted to be electrically connected to the door lock module 40. The DC-DC unit 501 is configured to achieve efficient and accurate voltage conversion.

[0062] In specific implementation methods, such as Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, 8, and 9, the voltage regulating module 50 includes a DC-DC unit 501. One end of the DC-DC unit 501 is adapted to be electrically connected to the first switching unit 201, and the other end of the DC-DC unit 501 is adapted to be electrically connected to the door lock module 40. Current flows out from the positive terminal of the power supply module 30, flows through the third switching unit 203 and the first switching unit 201, and then flows through the DC-DC unit 501. The DC-DC unit 501 reduces the high voltage to a low voltage of 12-24V, and then inputs it into the door lock module 40 to ensure the normal operation of the door lock module 40. The DC-DC unit 501 significantly improves the energy utilization rate of voltage conversion.

[0063] In an optional implementation, the voltage regulating module 50 further includes a transformer unit 502 and a rectifier unit 503.

[0066] In specific implementation methods, such as Figure 1 , 2 As shown in figures 3, 4, 5, 6, 7, 8, 9, 10, 11, and 13, the first end of the first switch unit 201 is adapted to be electrically connected to the second end of the third switch unit 203, the second end of the first switch unit 201 is adapted to be electrically connected to the DC-DC unit 501, and the third end of the first switch unit 201 is adapted to be electrically connected to the first control unit 101; the first end of the second switch unit 202 is adapted to be electrically connected to the positive terminal of the power module 30, the second end of the second switch unit 202 is adapted to be electrically connected to the door lock module 40, and the third end of the second switch unit 202 is adapted to be electrically connected to the first control unit 101; the first end of the third switch unit 203 is adapted to be electrically connected to the positive terminal of the power module 30, and the third ... door lock module 40 is adapted to be electrically connected to the door lock module 40, and the third end of the door lock module 40 is adapted to be electrically connected to the door lock module 40, and the third end of the door lock module 40 is adapted to be electrically connected to the door lock module 40, and the third end of the door lock module 40 is adapted to be electrically connected to the door lock module 40, and the third end of the door lock module 40 is adapted to be electrically connected to the door lock module 40, and the third end of the door lock module 40 is adapted to be electrically connected to the door lock module 4 The third terminal of component 203 is suitable for electrical connection with the first control unit 101. Under normal battery system conditions, the first control unit 101 controls the first switch unit 201 to close and the second switch unit 202 to open. Current flows out from the positive terminal of the power module 30, through the third switch unit 203, the first switch unit 201, the DC-DC unit 501, the transformer unit 502, the rectifier unit 503, and into the door lock module 40, thereby unlocking the door. Under abnormal battery system conditions, the first control unit 101 controls the second switch unit 202 to close and the first switch unit 201 to open. Current flows out from the positive terminal of the power module 30, through the second switch unit 202, and into the door lock module 40, thereby unlocking the door.

[0067] In an optional implementation, the third terminal of the first switch unit 201 is also electrically connected to the second control unit 102, and the third terminal of the second switch unit 202 is also electrically connected to the second control unit 102. The first switch unit 201 and the second switch unit 202 are respectively electrically connected to the second control unit 102.

[0068] In specific implementation methods, such as Figures 1-13As shown, the first terminal of the first switching unit 201 is adapted to be electrically connected to the second terminal of the third switching unit 203, the second terminal of the first switching unit 201 is adapted to be electrically connected to the voltage regulating module 50, the third terminal of the first switching unit 201 is adapted to be electrically connected to the second control unit 102, the first terminal of the third switching unit 203 is adapted to be electrically connected to the power module 30, the first terminal of the second switching unit 202 is adapted to be electrically connected to the power module 30, the second terminal of the second switching unit 202 is adapted to be electrically connected to the door lock module 40, and the third terminal of the second switching unit 202 is adapted to be electrically connected to the second control unit 102.

In the event of a battery system malfunction, switch 102 controls switch 202 to close and switch 201 to open, allowing current to flow out from the positive terminal of power module 30, through switch 202, and into door lock module 40, thus unlocking the door. The redundancy of switch 102 ensures that the door can also be unlocked via switch 102.

[0069] In one optional implementation, when the door lock control system is powered on at low voltage and the first switch unit 201 is working normally, the first control unit 101 is used to control the first switch unit 201 to close and control the second switch unit 202 to open. The first control unit 101 supplies power to the door lock module 40 through the first switch unit 201, which facilitates the unlocking of the door lock module 40 when the battery system is normal.

[0070] In specific implementation methods, such as Figures 1-13 As shown, after the door lock control system is powered on at low voltage, the first end of the first switch unit 201 is adapted to be electrically connected to the second end of the third switch unit 203, the second end of the first switch unit 201 is adapted to be electrically connected to the DC-DC unit 501, and the third end of the first switch unit 201 is adapted to be electrically connected to the first control unit 101.

The normal operation of the first switch unit 201 also includes the unlocking of the car door. At this time, the current flows out from the positive terminal of the power module 30, flows through the third switch unit 203, the first switch unit 201, the DC-DC unit 501, the transformer unit 502, the rectifier unit 503, and flows into the door lock module 40 to unlock the car door. The arrangement of the first control unit 101 and the first switch unit 201 facilitates the unlocking of the car door when the battery system is normal.

[0071] In one optional implementation, when the door lock control system is powered on at low voltage and the first control unit 101 receives a fault signal from the first switch unit 201, the first control unit 101 controls the second switch unit 202 to close and controls the first switch unit 201 to open. The first control unit 101 supplies power to the door lock module 40 through the second switch unit 202, which facilitates the unlocking of the door lock module 40 when the battery system is abnormal.

[0072] In specific implementation methods, such as Figures 1-13 As shown, after the door lock control system is powered on at low voltage, the first end of the second switch unit 202 is adapted to be electrically connected to the positive terminal of the power module 30, the second end of the second switch unit 202 is adapted to be electrically connected to the door lock module 40, and the third end of the second switch unit 202 is adapted to be electrically connected to the first control unit 101.

Current flows out from the positive terminal of the power module 30, through the second switch unit 202, and into the door lock module 40, thereby unlocking the door. The arrangement of the first control unit 101 and the second switch unit 202 facilitates unlocking the door in the event of a battery system malfunction.

[0073] In one optional implementation, when the door lock control system is powered on at low voltage and the first control unit 101 receives an external signal, the first control unit 101 controls the second switch unit 202 to close and controls the first switch unit 201 to open. The first control unit 101 supplies power to the door lock module 40 through the second switch unit 202, which facilitates the unlocking of the door lock module 40 when the battery system is abnormal.

[0074] In specific implementation methods, such as Figures 1-13 As shown, after the door lock control system is powered on at low voltage, the first end of the second switch unit 202 is adapted to be electrically connected to the positive terminal of the power module 30, the second end of the second switch unit 202 is adapted to be electrically connected to the door lock module 40, and the third end of the second switch unit 202 is adapted to be electrically connected to the first control unit 101.

The first control unit 101 controls the second switch unit 202 to close and the first switch unit 201 to open. Current flows out from the positive terminal of the power module 30, flows through the second switch unit 202, and flows into the door lock module 40, thereby unlocking the door. The arrangement of the first control unit 101 and the second switch unit 202 facilitates the unlocking of the door when the system receives an external emergency signal.

[0075] In one optional implementation, the external signal includes at least one of the following: collision signal, passenger compartment smoke alarm, vehicle alarm signal, and door status signal. The collision signal, passenger compartment smoke alarm, and vehicle alarm signal are all relatively intuitive and can reflect the abnormality of the vehicle, which makes it easier for the first control module 10 to receive and control the second switch unit 202 to close.

[0076] In specific implementation methods, such as Figures 1-13 As shown, the control system also includes a signal receiving module 60, which is electrically connected to the first control unit 101. The signal receiving module 60 is used to receive external signals and input them into the first control unit 101. The external signals include at least one of a collision signal, a passenger compartment smoke alarm, and a vehicle alarm signal. After the first control unit 101 receives the above-mentioned abnormal external signal through the signal receiving module 60, it controls the second switch unit 202 to close and the first switch unit 201 to open.
