[0008] In some embodiments, the child lock includes a first child lock and a second child lock. The response to the current control state of the child lock not matching the current control state of the rear window, generating an adjustment control instruction matching the current control state of the rear window, and sending the adjustment control instruction to the child lock includes: In response to the first child lock and / or the second child lock not matching the current control state of the rear window, determining the first child lock and / or the second child lock that does not match as a target child lock; Generating an adjustment control instruction matching the current control state of the rear window and sending the adjustment control instruction to the target child lock.

DETAILED DESCRIPTION

[0018] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0019] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood as the general meaning understood by those skilled in the art to which the embodiments of the present application belong. The terms “first”, “second” and the like used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components.

The terms “connect” or “connected” and the like are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “up”, “down”, “left”, “right” and the like are only used to represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships may also change accordingly.

[0020] HUT: Head Unit, host controller.

[0021] CAN line: Controller Area Network, CAN bus, which is a serial communication protocol bus for real-time applications.

[0022] LIN line: Local Interconnect Network, LIN connection line.

[0023] In the related art, the control of the child lock and the rear window is multiplexed with one control. Pressing the control, the rear window state (rear window glass lifting enablement) and the child lock (driving unlocking or locking) are both toggled once. Among them, the control signal of the rear window goes through the CAN line, and the control signal of the child lock goes through the hard line.

[0024] The related art will have the following three defects: Defect one, the user quickly presses the control twice in succession, for example, the first time is a locking signal, and the second time is an unlocking signal. Since the rear window response is a CAN network communication, the rear window response will be relatively timely and can be normally executed. The child lock is a child lock relay driven by the central electronic control module through a hard wire, and the child lock motor is driven by the output voltage of the child lock relay. The child lock motor needs a relatively long time (for example, about 300 ms) to drive and run, and other control instructions cannot be applied during the time when the child lock motor is driving and running, for example, the child lock motor cannot apply a locking control instruction triggered later during the execution of the unlocking drive. Thus, the state of the child lock may not be consistent with the state required by the user.

[0025] Defect two: during the unlocking process of the child lock, the child lock motor has power supply at both ends (the unlocking end and the locking end). Theoretically, the voltages at both ends should be the same, and the child lock motor remains in the unlocking state without action. The voltage is the voltage of the whole vehicle. If there is a voltage difference between the unlocking end and the locking end of the child lock (a voltage difference may be caused by different lengths of wire harnesses, different impedances, etc.), the voltage at the locking end is higher, and the lock catch of the child lock will move a little in the locking direction. Each time the vehicle is powered on, it will move a little in the locking direction. After a large number of times, the lock catch of the child lock will move to the locking position little by little, and the child lock will be locked without the user operating the child lock.

[0026] Defect three: when the child lock is unlocked, the child lock motor does not run to the position, causing the mechanical structure of the lock catch of the child lock to occasionally jam, which causes the user to want to unlock the child lock, but the child lock is not actually unlocked, so that the child lock remains in the locked state.

[0027] Based on the above, the embodiments of the present application will be described in detail in combination with the drawings.

[0028] Reference Figure 1 It is an application scenario diagram of a child lock control method of a vehicle provided by an embodiment of the present application. The application scenario includes an electronic controller 101, a control 102, a rear window 103, and a child lock 104. The rear window 103 communicates with the electronic controller 101 through a CAN line, and the child lock 104 communicates with the electronic controller 101 through a hard wire. The electronic controller 101, the control 102, the rear window 103, and the child lock 104 are all arranged on the vehicle.

[0029] The control 102 is connected with the electronic controller 101, used to receive the control operation of the user, and generate corresponding control instructions (including: an unlocking instruction or a locking instruction), and send the control instructions to the electronic controller 101 to control the rear window 103 and the child lock 104 to execute the corresponding control instructions. The control 102 is the same control for the rear window 103 and the child lock 104, and can control the locking or unlocking of the rear window 103 and the child lock 104 at the same time.

[0030] The electronic controller 101 acquires the rear window current control state of the rear window 103 and the child lock current control state of the child lock 104, and then determines whether the two states match. If the two states match, no adjustment is performed. If the two states do not match, it is proved that the child lock current control state of the child lock 104 is incorrect, and thus the corresponding adjustment control instruction is determined according to the rear window current control state. In this way, the adjustment control instruction can be sent to the child lock 104, so that the child lock 104 adjusts the child lock current control state according to the adjustment control instruction, so that the child lock 104 and the rear window 103 can be state-matched after adjustment.

[0031] The application scenario of the application is described below. Figure 1 It should be noted that the above application scenario is only shown for the purpose of facilitating understanding of the spirit and principles of the application, and the embodiments of the application are not limited in this respect. On the contrary, the embodiments of the application can be applied to any applicable scenario.

[0032] The child lock control method of the vehicle according to the embodiments of the application is proposed, and the unlocking or locking of the child lock and the rear window is controlled by the same control.

[0033] The control can be a hardware switch arranged in the vehicle interior, or a software switch arranged on the screen of the head unit (HUT). The user can trigger the control to achieve the unlocking or locking of the child lock and the rear window.

[0034] The control can switch between the unlocking and locking states by the number of touches, for example, the child lock and the rear window are in the unlocking state, and the hardware switch is touched to switch from the unlocking state to the locking state. Or, the child lock and the rear window are in the locking state, and the hardware switch is touched to switch from the locking state to the unlocking state.

[0035] In addition, the control can represent the current state of the child lock and the rear window.

[0036] For example, a locking icon is arranged on the hardware control, and the locking icon is on to indicate that the child lock and the rear window are in the locking state, and the locking icon is off to indicate that the child lock and the rear window are in the unlocking state.

[0037] For example, a corresponding display content is arranged on the software control, and the child lock and the rear window are in the locking state to display the locking-related text or symbol, and the child lock and the rear window are in the unlocking state to display the unlocking-related text or symbol.

[0038] The child lock control method of the vehicle according to the embodiments of the application is applied to an electronic controller on the vehicle, and the electronic controller is connected to the control, the rear window and the child lock, as shown in Figure 2 The method comprises: Step 201, obtaining the current control state of the rear window and the current control state of the child lock.

[0039] In implementation, the rear window communicates with the electronic controller through a bus (for example, CAN line), and the child lock communicates with the electronic controller through a hard line.

[0040] After the vehicle is powered on, the electronic controller obtains the current control state of the rear window and the current control state of the child lock in real time or at a fixed time. The current control state of the rear window is relatively accurate because the response is fast due to the control through the bus communication, and the current control state of the rear window can be used as a reference to judge the current control state of the child lock.

[0041] Step 202, judging whether the current control state of the child lock matches the current control state of the rear window.

[0042] In implementation, the current control state of the child lock is matched with the current control state of the rear window by taking the current control state of the rear window as a reference. If they are consistent, it is determined that the judgment result is that they match, otherwise, it is determined that the judgment result is that they do not match.

[0043] Normally, the current control state of the child lock is consistent with the current control state of the rear window, so if they are not consistent, it proves that the current control state of the child lock has a fault and needs to be corrected and adjusted.

[0044] Step 203, in response to the current control state of the child lock not matching the current control state of the rear window, generating an adjustment control instruction matching the current control state of the rear window, and sending the adjustment control instruction to the child lock for the child lock to adjust the current control state of the child lock according to the adjustment control instruction.

[0045] In implementation, if the electronic controller determines that the current control state of the child lock does not match the current control state of the rear window, it proves that the current control state of the child lock is incorrect and needs to be adjusted. In order to ensure that the rear window and the child lock always maintain the same state, the electronic controller generates a corresponding adjustment control instruction according to the current control state of the rear window, and then sends it to the child lock through the hard line. In this way, after receiving the adjustment control instruction, the child lock adjusts the current control state of the child lock, so that the adjusted control state of the child lock is consistent with the current control state of the rear window.

[0046] By the above scheme, because the unlocking or locking of the child lock and the rear window is controlled by the same control, and the state of the rear window is generally accurate, the current control state of the rear window and the current control state of the child lock are obtained, and then it is judged whether they match. If they match, no adjustment is made. If they do not match, it proves that the current control state of the child lock is incorrect, so the corresponding adjustment control instruction is determined according to the current control state of the rear window. In this way, the adjustment control instruction can be sent to the child lock, so that the child lock adjusts the current control state of the child lock according to the adjustment control instruction, so that the child lock and the rear window can match in state after adjustment, avoiding the situation that the child lock is in an incorrect state, improving the practicality of the child lock, and improving the user experience.

[0047] As a preferred embodiment, the above process is executed on the premise that the current control state of the rear window is accurate by default. However, the current control state of the rear window is not necessarily always accurate, so it is necessary to identify and judge the current control state of the rear window before step 201 is implemented. The specific process is as follows: Step A1, determine the current control state of the control and the current control state of the rear window.

[0048] In specific implementation, the current control state of the control includes: an unlocked state or a locked state. The current control state of the control is a control state that can directly indicate the user's demand.

[0049] Step A2, compare and judge the current control state of the control and the current control state of the rear window to obtain a judgment result.

[0050] Step A3, in response to the judgment result being consistent, it is determined that the current control state of the rear window is correct, and the process of steps 201 to 203 is continued.

[0051] Alternatively, step A4, in response to the judgment result being different, it is determined that the current control state of the rear window is incorrect. At this time, the current control state of the rear window needs to be adjusted to be consistent with the current control state of the control before the process of steps 201 to 203 is continued.

[0052] By the above scheme, the current control state of the rear window can always be consistent with the current control state of the control, ensuring the accuracy of the current control state of the rear window, so that the process of judging the state of the child lock based on the current control state of the rear window is more accurate.

[0053] In some embodiments, a counter for the number of times of execution of the adjustment control instruction is set in advance, and the counter is cleared when the vehicle is powered on.

[0054] In a specific implementation, the central electronic control module sets a counter for the number of times of execution of the adjustment control instruction, so as to count the number of times of execution of the adjustment control instruction, and to avoid excessive accumulation of the counter, the counter is reset when the vehicle is powered on.

[0055] Step 201 includes: Step 2011, determining whether the number of the counter is less than a threshold number of times.

[0056] Step 2012, in response to the number of the counter being less than the threshold number of times, obtaining the current control state of the rear window and the current control state of the child lock.

[0057] In a specific implementation, since the counter is reset each time the vehicle is powered on, the threshold number of times is the maximum number of times of execution of the adjustment control instruction after the vehicle is powered on, for example, the threshold number of times is set to 1, 2 or 3, preferably 1, and is set according to actual needs.

[0058] If the number of the counter is less than the threshold number of times, it proves that the processes of steps 202 and 203 can still be executed, and after the execution of steps 202 and 203 is completed, the number of the counter is increased by 1; if the number of the counter is greater than or equal to the threshold number of times, it proves that the maximum number of times of execution of the adjustment control instruction after the current power-on has been reached, so the process of obtaining the current control state of the rear window and the current control state of the child lock is stopped, and the processes of steps 202 and 203 are also stopped.

[0059] The number of times of execution of the above process of adjusting the child lock motor in one power-on cycle (i.e. one power-on to power-off cycle) cannot exceed the threshold number of times (for example, 1 or 2), in order to avoid repeatedly executing the above process when the child lock relay, child lock motor or other electrical components fail, so that the child lock relay, child lock motor or other electrical components are prone to ablation.

[0060] Through the above scheme, it can be ensured that the number of times of execution of the corresponding adjustment control instruction in each power-on cycle of the vehicle is less than or equal to the threshold number of times, so that if the child lock fails, the state of the child lock is adjusted frequently, which can prevent the failure of the child lock from being aggravated, and the repairability of the child lock when it fails is ensured.

[0061] In some embodiments, step 203 includes: Step 2031, in response to the current control state of the child lock not matching the current control state of the rear window, starting a timer.

[0062] In implementation, if the electronic controller finds that the current control state of the child lock does not match the current control state of the rear window, it is possible that the current control state of the child lock is wrong, or the child lock is in the process of state switching and has not completed the state switching process. In order to give the child lock a certain state switching time, timing is performed at this time.

[0063] For example, the child lock and the rear window, when the state is 0, it indicates an unlocked state, and when the state is 1, it indicates a locked state. If the current control state of the child lock does not match the current control state of the rear window, it is divided into: (1) the current control state of the child lock is 0, in the unlocked state, and the current control state of the rear window is 1, in the locked state; or (2) the current control state of the child lock is 1, in the locked state, and the current control state of the rear window is 0, in the unlocked state.

[0064] Step 2032, after the first predetermined timing duration ends, the current control state of the child lock is reacquired, and whether the reacquired current control state of the child lock matches the current control state of the rear window is judged again.

[0065] In implementation, a timer is provided in the electronic controller, and the timing of the first predetermined timing duration can be executed in two cases: First, after the current control state of the child lock does not match the current control state of the rear window, the electronic controller acquires the clock signal of the timer, adds the first predetermined timing duration to the clock signal as the termination time, and generates a termination time signal when the timer reaches the termination time to determine the end of timing.

[0066] Second, after the current control state of the child lock does not match the current control state of the rear window, the electronic controller sends a countdown instruction to the timer, and the timer starts the countdown of the first predetermined timing duration. When the countdown is 0, the timer generates a termination time signal to determine the end of timing.

[0067] The above two timing methods can be selected according to actual needs as the timing scheme of the first predetermined timing duration.

[0068] If the current control state of the rear window does not change during the timing of the first predetermined timing duration, the current control state of the child lock will be reacquired again after the first predetermined timing duration ends. In this way, the reacquired current control state of the child lock can be compared with the current control state of the rear window. If they are consistent, it proves that the child lock has returned to normal and there is no need to adjust the control. Otherwise, step 2033 will be executed.

[0069] In addition, if the current control state of the rear window changes during the timing of the first predetermined timing duration, the timing will be stopped, and the process will return to step 201 to start again.

[0070] In response to the re-acquired current control state of the child lock not matching the current control state of the rear window, step 2033 generates an adjustment control instruction matching the current control state of the rear window and sends the adjustment control instruction to the child lock.

[0071] In specific implementation, if the electronic controller determines that the re-acquired current control state of the child lock still does not match the current control state of the rear window after the first predetermined timing duration ends (i.e., the re-acquired current control state of the child lock is inconsistent with the current control state of the rear window), it proves that the current control state of the child lock is indeed incorrect, and the child lock needs to be adjusted. In order to ensure that the rear window and the child lock always maintain a consistent state, the electronic controller generates a corresponding adjustment control instruction according to the current control state of the rear window and then sends it to the child lock through a hard line. In this way, after receiving the adjustment control instruction, the child lock adjusts the current control state of the child lock so that the adjusted control state of the child lock is consistent with the current control state of the rear window.

[0072] For example, (1) the current control state of the child lock is 0 in the unlocked state, the current control state of the rear window is 1 in the locked state, and the electronic controller generates a lock instruction as the adjustment control instruction and sends it to the child lock to adjust the child lock from the unlocked state 0 to the locked state 1.

[0073] For another example, (2) the current control state of the child lock is 1 in the locked state, the current control state of the rear window is 0 in the unlocked state, and the electronic controller generates an unlock instruction as the adjustment control instruction and sends it to the child lock to adjust the child lock from the locked state 1 to the unlocked state 0.

[0074] Through the above scheme, when it is found that the current control state of the child lock does not match the current control state of the rear window, the situation of misjudgment can be avoided, the first predetermined timing duration is timed, and after the timing ends, it is determined that the current control state of the child lock does not match the current control state of the rear window. It can be accurately determined that the current control state of the child lock is indeed incorrect, and the child lock needs to be adjusted. Then, the adjustment control instruction corresponding to the current control state of the rear window is generated, the child lock is controlled by the adjustment control instruction to adjust the current control state of the child lock, and the control state of the child lock is adjusted to be consistent with the current control state of the rear window, so that the control state of the child lock is correct.

[0075] In some embodiments, the child lock includes a first child lock and a second child lock.

[0076] In specific implementation, the child lock on the vehicle is generally arranged on the rear door, and the child lock includes a first child lock and a second child lock. The first child lock is arranged on the left rear door, and the second child lock is arranged on the right rear door.

[0077] The first child lock and the second child lock are connected with the electronic controller, and the states of the first child lock and the second child lock are simultaneously controlled by the electronic controller according to the corresponding control.

[0078] Step 203 comprises: Step B1, in response to the first child lock and / or the second child lock not matching the current control state of the rear window, determining the first child lock and / or the second child lock not matching as a target child lock.

[0079] In specific implementation, the first child lock and the second child lock can appear: 1. Both of the current control states of the two child locks do not match the current control state of the rear window, and the corresponding target child lock is the first child lock and the second child lock; for example, the current control states of the first child lock and the second child lock are 0 in the unlocked state, and the current control state of the rear window is 1 in the locked state; for another example, the current control states of the first child lock and the second child lock are 1 in the locked state, and the current control state of the rear window is 0 in the unlocked state.

[0080] 2. The current control state of the first child lock does not match the current control state of the rear window, and the corresponding target child lock is the first child lock; for example, the current control state of the first child lock is 0 in the unlocked state, and the current control state of the rear window is 1 in the locked state; for another example, the current control state of the first child lock is 1 in the locked state, and the current control state of the rear window is 0 in the unlocked state.

[0081] 3. The current control state of the second child lock does not match the current control state of the rear window, and the corresponding target child lock is the second child lock; for example, the current control state of the second child lock is 0 in the unlocked state, and the current control state of the rear window is 1 in the locked state; for another example, the current control state of the second child lock is 1 in the locked state, and the current control state of the rear window is 0 in the unlocked state.

[0082] Step B2, generating an adjustment control instruction matching the current control state of the rear window, and sending the adjustment control instruction to the target child lock.

[0083] In specific implementation, in order to ensure that the rear window and the child lock always maintain the same state, the electronic controller generates a corresponding adjustment control instruction according to the current control state of the rear window, and then sends it to the corresponding target child lock through a hard line. In this way, the target child lock adjusts the current control state, and finally the current control states of the first child lock and the second child lock are consistent with the current control state of the rear window.

[0084] By the above scheme, the error state of the first child lock and / or the second child lock can be found in time, and the error state is adjusted to be consistent with the current control state of the rear window in time, so that the first child lock and the second child lock both maintain correct control states, and the practicability of the first child lock and the second child lock is improved.

[0085] In some embodiments, the generating of the adjustment control instruction matched with the current control state of the rear window in step 203 comprises: Step C1, determining that the current control state of the rear window is a rear window unlocking state, and generating a child lock unlocking control instruction.

[0086] In specific implementation, when it is determined that the current control state of the child lock is incorrect, if the current control state of the rear window is the rear window unlocking state, in order to ensure consistency with the current control state of the rear window, a child lock unlocking control instruction is generated and sent to the child lock, and then the child lock adjusts the current control state to the unlocking state according to the child lock unlocking control instruction, so that the current control state of the child lock is consistent with the rear window unlocking state.

[0087] Alternatively, step C2, determining that the current control state of the rear window is a rear window locking state, and generating a child lock locking control instruction.

[0088] In specific implementation, when it is determined that the current control state of the child lock is incorrect, if the current control state of the rear window is the rear window locking state, in order to ensure consistency with the current control state of the rear window, a child lock locking control instruction is generated and sent to the child lock, and then the child lock adjusts the current control state to the locking state according to the child lock locking control instruction, so that the current control state of the child lock is consistent with the rear window locking state.

[0089] By the above scheme, the current control state of the rear window is taken as a correct reference, when it is found that the current control state of the child lock is incorrect, a child lock unlocking control instruction or a child lock locking control instruction corresponding to the current control state of the rear window is sent to the child lock in time, so that the child lock adjusts the control state to be consistent with the current control state of the rear window, and the correctness of the control state of the child lock is ensured, and the situation that the child lock cannot be corrected when the error state occurs is reduced.

[0090] In some embodiments, the child lock comprises a child lock relay and a child lock motor.

[0091] In specific implementation, the child lock motor comprises a first child lock motor and a second child lock motor, the first child lock motor is arranged on the left rear door and is used for unlocking or locking the left rear door, and the second child lock motor is arranged on the right rear door and is used for unlocking or locking the right rear door.

[0092] The electronic controller is connected with the child lock relay through a hard line, and the child lock relay is connected with the child lock motor through a hard line.

[0093] After step 203, the method further comprises: In step 204, the child lock relay receives the adjustment control instruction through the hard line, determines a voltage signal according to the adjustment control instruction, and sends the voltage signal to the child lock motor.

[0094] In step 205, the child lock motor receives the voltage signal and drives execution according to the voltage signal to adjust the current control state of the child lock.

[0095] In specific implementation, if the adjustment control instruction is a child lock unlocking control instruction, the child lock relay generates a first voltage signal for keeping the voltage across the child lock motor consistent, sends the first voltage signal to the child lock motor, so that there is no voltage difference across the child lock motor, and the child lock motor adjusts the current control state of the child lock to an unlocking state.

[0096] If the adjustment control instruction is a child lock locking control instruction, the child lock relay generates a second voltage signal for keeping the voltage across the child lock motor inconsistent, sends the second voltage signal to the child lock motor, so that there is a predetermined voltage difference across the child lock motor, and the child lock motor adjusts the current control state of the child lock to a locking state.

[0097] Through the above scheme, the child lock relay can cooperate with the child lock motor to accurately execute the adjustment control instruction, and then accurately complete the adjustment process of the current control state of the child lock, so that the control state of the child lock after adjustment is consistent with the current control state of the rear window, and the abnormal situation of the child lock is reduced.

[0098] In some embodiments, after step 203, the method further comprises: In step 206, after the second predetermined timing duration ends, it is determined whether the current control state of the child lock is adjusted.

[0099] In specific implementation, after the electronic controller sends the adjustment control instruction, the electronic controller starts a timing process of a second predetermined timing duration, and the timing process of the second predetermined timing duration is divided into two cases: In the first case, after the electronic controller sends the adjustment control instruction, the electronic controller acquires a clock signal of the timer, adds the second predetermined timing duration to the clock signal as a termination time, and generates a termination time signal after the timer reaches the termination time to determine that the timing ends.

[0100] Second, the electronic controller sends a countdown instruction to the timer after sending the adjustment control instruction, and the timer starts the countdown of the second predetermined timing duration. When the countdown is 0, the timer generates a termination time signal to determine the end of timing.

[0101] The above two timing methods can be selected according to actual needs as the timing scheme of the second predetermined timing duration. The second predetermined timing duration is greater than or equal to the first predetermined timing duration.

[0102] Timing for the second predetermined timing duration provides sufficient time for the adjustment process of the child lock. After the second predetermined timing duration ends, it is determined whether the current control state of the child lock is adjusted.

[0103] The specific method for determining whether the adjustment is completed is: (1) Determine whether the current control state of the child lock after the second predetermined timing duration is consistent with the current control state of the rear window. If they are consistent, it means that the adjustment is completed. If they are not consistent, it means that the adjustment is not completed.

[0104] Alternatively, (2) Determine whether the current control state of the child lock after the second predetermined timing duration is consistent with the state corresponding to the adjustment control instruction. If it is, it means that the adjustment is completed. If not, it means that the adjustment is not completed.

[0105] Step 207, in response to the child lock current control state not being adjusted, it is determined that the child lock has failed, and a fault information is generated. The fault information is prompted.

[0106] In specific implementation, if the child lock current control state is not adjusted after the second predetermined timing duration, it proves that the child lock has failed and cannot perform control state adjustment. At this time, a fault information is generated and sent to the car machine (HUT) for display to remind the user that the child lock has failed and needs to be repaired.

[0107] Through the above scheme, the adjustment process of the child lock is provided with a second predetermined timing duration, so that the child lock has sufficient time to complete the adjustment process. After the second predetermined timing duration ends, if the current control state of the child lock is still not adjusted, it proves that the child lock cannot perform control state adjustment, and the child lock has failed. Then a fault information is generated to prompt the user, so that the user can know the fault condition of the child lock in time, and then repair the child lock in time to avoid the faulty child lock affecting the user's riding experience.

[0108] The child lock control method of the vehicle of the embodiment of the application is described below with a specific embodiment. As shown in the structure schematic diagram of Figure 3 The specific process is as follows: The user can trigger the control 102 to unlock or lock the child lock 104 and the rear window 103, which includes: The hardware control 102 is arranged in the vehicle and is connected to the electronic controller 101 through a LIN line. Alternatively, the software control 102 is arranged on the screen of the head unit (HUT), and the head unit (HUT) is connected to the electronic controller 101 through a CAN line.

[0109] (1) The electronic controller 101 receives the current control state of the rear window (for example, the current control state of the rear window is in the unlocked state) through the door module 1031 and the rear window lifter 1032 through the CAN line. At the same time, the electronic controller 101 also receives the current control state of the first child lock fed back by the first child lock motor 1042 arranged on the left rear door, and the current control state of the second child lock fed back by the second child lock motor 1043 arranged on the right rear door.

[0110] (2) The electronic controller 101 compares the current control state of the first child lock and the current control state of the second child lock with the current control state of the rear window.

[0111] (21) If the current control state of the first child lock and the current control state of the second child lock are consistent with the current control state of the rear window, the electronic controller 101 does not act.

[0112] (22) If at least one of the current control state of the first child lock and the current control state of the second child lock is different from the current control state of the rear window, the electronic controller 101 starts timing for a first predetermined timing duration (for example, 500 ms); after the timing is over, the electronic controller 101 compares the current control state of the first child lock and the current control state of the second child lock with the current control state of the rear window again.

[0113] (221) If the current control state of the first child lock and the current control state of the second child lock are consistent with the current control state of the rear window after the comparison, no action is taken.

[0114] (222) If at least one of the current control state of the first child lock and the current control state of the second child lock is different from the current control state of the rear window, an adjustment control instruction corresponding to the current control state of the rear window is generated; the adjustment control instruction is sent to the child lock relay 1041, the child lock relay 1041 generates a corresponding voltage signal according to the adjustment control instruction, and sends the voltage signal to the first child lock motor 1042 and the second child lock motor 1043, so as to adjust the current control state of the child lock by the first child lock motor 1042 and the second child lock motor 1043.

[0115] For example, the rear window current control state is the unlocking state, and the corresponding adjustment control instruction is the child lock unlocking control instruction. The child lock relay 1041 generates a first voltage signal that keeps the voltage across the child lock motor (i.e., the first child lock motor 1042 and / or the second child lock motor 1043) consistent, sends the first voltage signal to the child lock motor, so that there is no voltage difference across the child lock motor, and the child lock motor adjusts the current control state of the child lock to the unlocking state.

[0116] In addition, the number of times of executing the above process of adjusting the child lock motor in one power-on cycle (i.e., one power-on to power-off power consumption cycle) cannot exceed the number threshold (for example, 1 or 2), so as to avoid repeatedly executing the above process when the child lock relay, the child lock motor or other electrical elements fail, so that the child lock relay, the child lock motor or other electrical elements are prone to ablation.

[0117] In summary, the abnormal locking or unlocking of the child lock can be avoided, and the accuracy of the corresponding control state of the child lock can be effectively improved.

[0118] It should be noted that the method of the embodiments of the present application can be executed by a single device, such as a computer or a server.
