In addition, since the magnitude of the impact current value and the current value when the window motor is blocked are relatively close during each startup and operation of the window motor, the magnitude of the impact current value can reflect the magnitude of the current value when the window motor is blocked to a certain extent. According to the current value when the window motor is running and the blocking threshold of this cycle, the reference threshold of the next cycle is determined in this scheme, and the blocking threshold of the next cycle is dynamically determined by the reference threshold of the next cycle and the impact current value of the next cycle. The blocking threshold is used to determine whether the window motor is blocked. In this way, the misjudgment of the operating state of the window motor due to the inappropriate blocking threshold can be avoided, and the accuracy of determining the blocking of the window motor is improved. Not only does it not need to calibrate the reference threshold of the actual vehicle, but it is also adaptive to different windows, and the accuracy of detecting the blocking of the window motor is higher, thereby improving the reliability of protecting the window motor.

[0045] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.
[0046] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0047] First, the driving circuit of the window motor of the present disclosure is described. The window motor mentioned in the present disclosure can be driven by a relay. For example, a double relay can be used to drive the window to achieve the effect of controlling the window to rise or fall.
[0048] Figure 1 FIG. 1 is a schematic diagram of a window motor driving circuit according to an exemplary embodiment. Figure 1As shown, the drive circuit may include a power module, a first relay, a second relay, a window motor, a current detection resistor, and a current detection amplifier circuit. The first relay includes a first moving contact 1a, a second moving contact 2a, and a first static contact 1b. The second relay includes a third moving contact 3a, a fourth moving contact 4a, and a second static contact 2b.
[0049] The positive electrode of the power module is connected to the first moving contact and the third moving contact respectively. The second moving contact is connected to the fourth moving contact. The first static contact is connected to the second static contact through the window motor. One end of the current detection resistor is connected to the fourth moving contact, and the other end of the current detection resistor is connected to the negative electrode of the power module. The current detection amplifier circuit is connected in parallel with the current detection resistor.
[0050] like Figure 1 As shown, if the first relay and the second relay are controlled to act, the first relay and the second relay are Figure 1 In the state shown (the first static contact is connected to the second moving contact, and the second static contact is connected to the third moving contact), the circuit channel between the power module and the window motor is connected. In this channel, the current flows from the positive electrode of the power module, through the second relay, the window motor, the first relay, the current detection resistor to the negative electrode of the power module. The direction of the current passing through the window motor is as follows Figure 1 The direction from bottom to top as shown by the arrow in the middle makes the window motor rotate forward. In this way, the window can be driven up.
[0051] Figure 2 is a schematic diagram of a vehicle window motor driving circuit according to another exemplary embodiment.
[0052] like Figure 2 As shown, if the first relay and the second relay are controlled to act, the first relay and the second relay are Figure 2 The state shown (the first static contact is connected to the first moving contact, and the second static contact is connected to the fourth moving contact) can also conduct the circuit channel between the power module and the window motor. In this channel, the current flows from the positive electrode of the power module, through the first relay, the window motor, the second relay, the current detection resistor to the negative electrode of the power module. The direction of the current passing through the window motor is as follows Figure 2 The window motor is reversed from top to bottom as shown by the arrow in the figure. In this way, the window can be driven down.
[0053] In this way, by controlling the first relay and the second relay, the forward and reverse rotations of the window motor can be controlled, thereby driving the window to rise and fall.
[0054] The current detection resistor is connected in series with the window motor to detect the current of the window motor. The current of the current detection resistor and the current of the window motor may have a fixed operation relationship.
[0055] The current detection amplifier circuit is connected in parallel with the current detection resistor and is used to amplify the current flowing through the current detection resistor so as to more accurately detect the current of the window motor.
[0056] Figure 3 FIG. 1 is a flow chart of a vehicle window motor control method according to an exemplary embodiment. Figure 3 As shown, the method may include the following steps:
[0057] In step S101 , the inrush current value when the window motor is started is determined.
[0058] When the window motor is started, an impact current is generated. The impact current value when the window motor is started can be determined by using the method in the related art.
[0059] In step S102, the current value when the window motor is operating is determined.
[0060] In the present disclosure, the current value after the window motor generates an inrush current and before it stops can be referred to as the current value during operation. The inrush current value and the current value during operation can be obtained using a current sensor.
[0061] In step S103, the stall threshold of the current cycle is determined according to the inrush current value and the reference threshold of the current cycle.
[0062] The reference threshold value of this cycle may be predetermined or stored after being updated in the previous cycle. For example, when the window motor is operated for the first time or the user clears the previously stored data, the reference threshold value of this cycle may be a fixed value. When the reference threshold value of the previous cycle is stored, the reference threshold value of this cycle may be a value determined based on the previous reference threshold value.
[0063] In step S104, the operation of the window motor is controlled according to the current value of the window motor during operation and the stall threshold value of the current cycle.
[0064] The stall threshold value can be used to determine whether the window motor is stalled. For example, if the current value of the window motor when running is greater than the stall threshold value, it can be considered that the running state of the window motor at this time is stalled.
[0065] If the current value of the window motor when it is running is greater than or equal to the blocking threshold of this cycle, it can be determined that the window motor is blocked, that is, the window reaches the limit, which may cause the thermal protection of the window motor to start and make the window motor fail. In order to ensure the normal operation of the window motor and to protect the window motor, when the current value of the window motor when it is running is greater than or equal to the blocking threshold of this cycle, the window motor can be controlled to stop running.
[0066] If the current value of the window motor when it is running is less than the stall threshold value of this cycle, it can be determined that the window motor is working normally. Therefore, the window motor can be controlled to continue to run.
[0067] In step S105, the reference threshold of this cycle is updated according to the current value of the window motor when it is running and the stall threshold of this cycle, and the updated reference threshold is used as the reference threshold of the next cycle.
[0068] This solution adds a new threshold parameter, namely, a reference threshold. That is, based on the stall threshold of this cycle, the reference threshold of the next cycle is determined by considering the influence of the current value of the window motor when it is running (in this cycle). The stall threshold of the next cycle is determined based on the impact current value of the next cycle and the reference threshold of the next cycle.
[0069] Through the above technical scheme, the operation of the window motor is controlled according to the current value when the window motor is running and the blocking threshold of this cycle, and the window motor can be closed in time to protect the window motor and avoid failure of the window motor. In addition, since the magnitude of the impact current value and the current value when the window motor is blocked are relatively close during each startup and operation of the window motor, the magnitude of the impact current value can reflect the magnitude of the current value when the window motor is blocked to a certain extent. According to the current value when the window motor is running and the blocking threshold of this cycle, the reference threshold of the next cycle is determined in this scheme, and the blocking threshold of the next cycle is dynamically determined by the reference threshold of the next cycle and the impact current value of the next cycle. The blocking threshold is used to determine whether the window motor is blocked. In this way, the misjudgment of the operating state of the window motor due to the inappropriate blocking threshold can be avoided, and the accuracy of determining the blocking of the window motor is improved. Not only does it not need to calibrate the reference threshold of the actual vehicle, but it is also adaptive to different windows, and the accuracy of detecting the blocking of the window motor is higher, thereby improving the reliability of protecting the window motor.
[0070] In some possible implementations, step S104 may include step 201 and step 202 .
[0071] In step 201, when the window motor operation time does not reach the first time, if the current value of the window motor when running is greater than the stall threshold value of the current cycle for a duration greater than the second time, the window motor is controlled to stop running.
[0072] The first duration can represent the maximum duration that the window motor is allowed to run. Within the first duration, the window motor can complete a rise or fall. That is, if the window motor runs for the first duration, it can be determined that the window has reached the limit and the window motor has been blocked. The second duration can be used to determine whether the state of the current value is stable. If the current value of the window motor when running is greater than the blocking threshold of this cycle for a duration greater than the second duration, it can be determined that the state of the current value is stable.
[0073] When the window motor operation time does not reach the first time, if the current value of the window motor when it is running is greater than the current cycle blocking threshold value for a duration greater than the second time, it can be determined that the current value of the window motor when it is running is stable and the window motor is blocked, and the window motor can be controlled to stop running. The first time can be set to 8s, and the second time can be set to 200ms.
[0074] In some possible implementations, when the window motor has not run for a first time, if the current value of the window motor when running is greater than the stall threshold of this cycle for a duration not greater than a second time, it can be determined that the current value state of the window motor when running is unstable, and it may be that current interference causes the current value during operation to accidentally exceed the stall threshold of this cycle. It can be determined that the window has not reached the limit, that is, the operating state of the window motor is normal, and therefore, the window motor can be controlled to continue running.
[0075] In step S202, when the current value of the window motor during operation is not greater than the stall threshold value of the current cycle and the operation time of the window motor has reached a first time length, the window motor is controlled to stop operating.
[0076] When the current value of the window motor when running is not greater than the blocking threshold of this cycle, and the running time of the window motor has reached the first time, it can be determined that the window motor is blocked. This situation may be due to the fact that the blocking threshold value of this cycle is too large, resulting in the current value failing to reach the blocking threshold of this cycle when the window motor is actually blocked. The running time of the window motor has reached the first time, which can indicate that the window has reached the limit, that is, the window motor has been blocked. Therefore, the window motor can be controlled to stop running.
[0077] In some possible implementations, when the current value of the window motor during operation is not greater than the current cycle blocking threshold and the operation duration of the window motor does not reach the first duration, it can be determined that the window motor is operating normally. Therefore, the window motor can be controlled to continue operating.
[0078] In some possible implementations, step S105 may include step S301 and step S302.
[0079] In step S301, when the window motor operation duration has not reached the first duration, if the current value when the window motor is running is greater than the stall threshold of this cycle for a duration greater than the second duration, the reference threshold of this cycle is updated to the current value when the window motor is running that is greater than the stall threshold of this cycle.
[0080] When the window motor operation duration does not reach the first duration, if the duration of the current value when the window motor is running being greater than the stall threshold value of the current cycle is greater than the second duration, it can be considered that the current value when the window motor is running is stably greater than the stall threshold value of the current cycle, and the reference threshold value can be considered to be increased in the next cycle. The updated reference threshold value can be the current value when the window motor is running that is greater than the stall threshold value of the current cycle and lasts for more than the second duration.
[0081] In some possible implementations, when the window motor has not run for the first time, if the duration of the current value of the window motor being greater than the blocking threshold of the current cycle is not greater than the second time, it can be determined that the current value of the window motor is unstable, and it may be that the current interference causes the current value of the window motor to accidentally exceed the blocking threshold of the current cycle. It can be determined that the window has not reached the limit, that is, the running state of the window motor is normal, and therefore, the window motor can continue to be controlled.
[0082] In step S302, when the current value of the window motor when running is not greater than the stall threshold of this cycle and the running time of the window motor has reached a first time, the reference threshold of this cycle is updated to the current value when the running time of the window motor reaches the first time.
[0083] For example, when the current value of the window motor is running is not greater than the stall threshold value of this cycle, that is, the window motor stall is not detected according to the stall threshold value. When the window motor has been running for a first time, it is considered that the window has reached the limit and the window motor has been stalled, and it is considered that the stall threshold value of this cycle is too large. Therefore, the reference threshold value of this cycle can be updated to the current value when the window motor has been running for the first time, so that the reference threshold value of the next cycle is reduced on the basis of the reference threshold value of this cycle, which helps to obtain a lower stall threshold value in the next cycle.
[0084] In some possible implementations, after the window motor has been running for a first period of time, the window motor may be controlled to stop working, and the reference threshold may be updated to the current value when the window motor was last running.
[0085] In some possible implementations, when the current value of the window motor during operation is not greater than the current cycle blocking threshold and the window motor operation duration does not reach the first duration, it can be determined that the window motor is operating normally. Therefore, the window motor operation can continue to be controlled.
[0086] The increase in the number of window motor operation times and the aging of the rubber strip may cause the current value of the same window motor to increase or decrease with the increase in the number of operations. Correspondingly, the stall current value when the window motor is stalled may also increase or decrease. At this time, if the stall threshold value corresponding to the previous current value is still used to determine whether the window motor is stalled, it may lead to misjudgment of the window stall. Therefore, in order to accurately control the window motor, the reference threshold can be dynamically updated according to the change in the current value during actual operation. In this way, there is no need for actual vehicle calibration, and it can adapt to different windows, thereby improving the accuracy of controlling the window motor.
[0087] In some possible implementations, step S103 may include: determining the larger of the impact current value and the reference threshold of the current cycle as the stall threshold of the current cycle; or, determining the product of the larger of the impact current value and a coefficient less than 1 as the stall threshold of the current cycle.
[0088] If the impact current value is greater than or equal to the reference threshold value of this cycle, the impact current value can be determined as the stall threshold value of this cycle. If the impact current value is less than the reference threshold value of this cycle, the reference threshold value of this cycle can be determined as the stall threshold value of this cycle.
[0089] The product of the larger of the inrush current value and the reference threshold value of the current cycle and a coefficient less than 1 can be determined as the stall threshold of the current cycle. The coefficient less than 1 can be set to 0.95. Setting the product of the larger of the inrush current value and the reference threshold value of the current cycle and the coefficient less than 1 can appropriately reduce the stall threshold and avoid the stall threshold being too large.
[0090] In a possible embodiment, determining the impact current value when the window motor is started (step S101) may include: determining the maximum current value within a third time period from the start of the window motor start as the impact current value when the window motor is started.
[0091] If, according to experiments or experience, the surge current is generated within a predetermined time (e.g., 100 ms) after the window motor starts, the maximum current value within the predetermined time after the window motor starts can be determined as the surge current value when the window motor starts.
[0092] In this embodiment, the impact current value is determined by detecting the maximum current value within a period of time. The method is simple and the processing speed is fast.
[0093] In a possible embodiment, determining the current value of the window motor when it is running (step S102) includes: determining the current value after the third time period from the start of the window motor as the current value of the window motor when it is running.
[0094] After the third time period from when the window motor starts to start timing, it can be considered that the window motor is running stably, and the detected current value can be used to determine whether the motor is stalled. In this embodiment, the current detected after a period of time from when the window motor starts to start timing is used as the current value when the window motor is running, thereby avoiding misjudging the impact current value as the current value during normal operation, thereby improving the accuracy of determining whether the window motor is stalled.
[0095] Figure 4 FIG. 1 is a flow chart of a window motor control method according to another exemplary embodiment. Figure 4 As shown, the method may include the following steps:
[0096] 1) Start the window motor.
[0097] 2) Determine the inrush current value when the window motor starts and the current value when it is running.
[0098] 3) The product of the larger one of the impact current value and the reference threshold value of this cycle and a coefficient less than 1 is determined as the stall threshold value of this cycle.
[0099] 4) Determine whether the window motor operation time reaches a first time time.
[0100] 5) If the running time of the window motor reaches the first time, the window motor is controlled to stop running, and the reference threshold of this cycle is updated to the current value when the window motor stops.
[0101] 6) If the window motor operation time does not reach the first time length, further determine whether the current value of the window motor when it is running is greater than the stall threshold value of this cycle, and whether the duration is greater than the second time length.
[0102] 7) If the current value of the window motor when running is greater than the stall threshold value of this cycle and lasts longer than the second duration, the window motor is controlled to stop running, and the reference threshold of this cycle is updated to the current value when the window motor stops.
[0103] 8) If the current value when the window motor is running is not greater than the blocking threshold of this cycle, or the duration of the current value when the window motor is running being greater than the blocking threshold of this cycle is not greater than the second duration, the window motor can be controlled to continue running and the current value when the window motor is running can continue to be detected.

[0120] Through the above technical scheme, the operation of the window motor is controlled according to the current value when the window motor is running and the blocking threshold of this cycle, and the window motor can be closed in time to protect the window motor and avoid failure of the window motor. In addition, since the magnitude of the impact current value and the current value when the window motor is blocked are relatively close during each startup and operation of the window motor, the magnitude of the impact current value can reflect the magnitude of the current value when the window motor is blocked to a certain extent. According to the current value when the window motor is running and the blocking threshold of this cycle, the reference threshold of the next cycle is determined in this scheme, and the blocking threshold of the next cycle is dynamically determined by the reference threshold of the next cycle and the impact current value of the next cycle. The blocking threshold is used to determine whether the window motor is blocked. In this way, the misjudgment of the operating state of the window motor due to the inappropriate blocking threshold can be avoided, and the accuracy of determining the blocking of the window motor is improved. Not only does it not need to calibrate the reference threshold of the actual vehicle, but it is also adaptive to different windows, and the accuracy of detecting the blocking of the window motor is higher, thereby improving the reliability of protecting the window motor.
