Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method and device for controlling the raising and lowering of vehicle windows. Background Technology

[0002] The car window lift system includes a lifter, a motor, and a controller. The controller sends commands to the motor to drive the lifter and raise / lower the window based on user instructions. The motor typically includes an automatic lifting and anti-pinch module, providing these functions. Currently, when communication between the controller and the motor is normal, the automatic lifting and anti-pinch functions work correctly. However, if communication between the controller and the motor fails, the motor enters a degraded state, reverting to factory mode. In factory mode, the motor loses its automatic lifting and anti-pinch functions. Users will find that the windows cannot automatically lift or lower or prevent pinching when controlling the windows via the vehicle's power switch, resulting in a poor user experience. Summary of the Invention

[0010] If the communication between the motor and the controller is valid, after receiving the window lifting signal, the motor sends the window lifting signal to the controller, so that the controller generates a window lifting command based on the window lifting signal and sends the window lifting command to the motor.

[0024] Optionally, generating the window raising / lowering command based on the window raising / lowering signal and the power supply includes:

[0025] If the power supply is higher than a preset threshold, then a window raising / lowering command is generated based on the window raising / lowering signal, and the number of windows is the total number of all windows.

[0026] If the power supply is lower than the preset threshold, then a window raising / lowering command with a window count of 1 is generated based on the window raising / lowering signal.

[0046] The embodiments of the present invention provide a method and device for controlling the raising and lowering of vehicle windows, thereby solving the technical problem of how to reduce the impact of the failure of the motor of the vehicle window regulator on the user experience.

[0047] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] like Figure 1 As shown, the window lifting control method applied to the window regulator motor of this invention includes:

[0049] Step S11: After the vehicle is powered on, determine whether the communication between the motor and the controller is effective;

[0050] Step S12: If the communication between the motor and the controller fails, the automatic window lifting and anti-pinch functions of the motor will be effective.

[0051] Step S13: After receiving the window lifting signal from the window lifting switch, control the window lifting based on the window lifting signal.

[0052] In this embodiment of the invention, there are multiple ways to control the raising and lowering of vehicle windows, such as control via a window switch inside the vehicle, voice control, or remote control. The window raising / lowering signal emitted by the window switch is received by the motor and can be directly executed by the motor. Voice control commands and remote control commands are received by the motor controller and executed by the controller. The window raising / lowering switch can be a physical button or a virtual button on a display screen, and the window raising / lowering signal can be a signal to control the window to rise or a signal to control the window to fall.

[0053] Considering that the vehicle's power window switches are only effective after the vehicle is powered on, step S11, where the vehicle is powered on, signifies that the basic conditions for the user to use the power window switches are met, indicating that the user may use the power window switches. The motor can determine whether the LIN communication between the motor and the controller is valid by sending a detection signal to the controller and checking whether it receives a feedback signal from the controller. If a feedback signal is received from the controller, it means that the communication between the motor and the controller is valid; if no feedback signal is received from the controller, it means that the communication between the motor and the controller is invalid.

[0054] If the communication between the motor and the controller fails, the automatic window raising and lowering and anti-pinch functions of the motor will automatically fail. At this time, if the automatic window raising and lowering and anti-pinch functions of the motor are active, the motor can restore the automatic window raising and lowering and anti-pinch functions.

[0055] The system receives a window lift signal from the window switch, indicating that the user has pressed or clicked the window lift switch. Window lifting and lowering control based on the window lift signal includes: raising the window based on the signal controlling the window to rise, and lowering the window based on the signal controlling the window to fall. Since the automatic window lifting and anti-pinch functions of the motor are already active and effective, the window can automatically lift and lower and prevent pinching when controlled by the window lift signal. This prevents the automatic window lifting and anti-pinch functions from failing when the user uses the window lift switch, reducing the impact of these functions failing on the user experience. It should be noted that if communication between the motor and controller fails, the voice control and remote control functions for the windows will also fail, as these functions require the controller to control the motor.

[0056] Of course, in some embodiments of the present invention, there is also a situation where communication between the motor and the controller is effective. In this case, the automatic window lifting and anti-pinch functions of the motor are effective, and there is no need to process the automatic window lifting and anti-pinch functions of the motor. The motor needs to send the window lifting signal to the controller for processing. Therefore, after step S11, the window lifting control method applied to the motor further includes: if the communication between the motor and the controller is effective, after receiving the window lifting signal, the window lifting signal is sent to the controller, so that the controller generates a window lifting command based on the window lifting signal and sends the window lifting command to the motor; and the window lifting is controlled based on the window lifting command.

[0057] When communication between the motor and the controller is effective, the raising and lowering of the window requires the cooperation of the controller and the motor. Therefore, embodiments of the present invention also provide, for example... Figure 2 The window lifting control method shown for the controller includes:

[0058] Step S21: In response to the window lifting signal sent by the motor, generate a window lifting command based on the window lifting signal;

[0059] Step S22: Send the window lifting command to the motor so that the motor controls the window lifting based on the window lifting command.

[0060] The controller generates window raising / lowering commands based on window raising / lowering signals, which may include: generating window raising / lowering commands based on window raising / lowering signals, and generating window lowering / lowering commands based on window lowering / lowering signals.

[0061] Considering that users sometimes control all windows to rise or fall simultaneously with a single button, but this puts a significant load on the power supply, insufficient power can lead to low voltage, affecting the vehicle's normal operation and potentially preventing it from starting. To mitigate the impact of simultaneous window raising or lowering on normal vehicle operation, step S21, which generates a window raising / lowering command based on the window raising / lowering signal, may include: if the window raising / lowering signal is a simultaneous window raising / lowering signal, obtaining the motor's power supply level; and generating a window raising / lowering command based on the window raising / lowering signal and the power supply level. The window raising / lowering command includes the number of windows controlled to rise or fall simultaneously, and the number of windows is positively correlated with the power supply level. This means that the more power the battery has, the more windows can be controlled to rise and fall simultaneously. Assuming a total of four windows, the window raising / lowering commands generated based on the window raising / lowering signals and the battery level can include: if the battery level is above 30%, a command to control all four windows simultaneously; if the battery level is between 20% and 30%, a command to control three windows simultaneously; if the battery level is between 10% and 20%, a command to control two windows simultaneously; and if the battery level is below 10%, a command to control one window simultaneously. This provides four window raising / lowering modes.

[0062] In addition, the window raising / lowering command generated based on the window raising / lowering signal and power level can also include: if the power level is higher than a preset threshold, generating a window raising / lowering command with the total number of windows; if the power level is lower than the preset threshold, generating a window raising / lowering command with only one window. The preset threshold can be 10%. This effectively provides only two window raising / lowering modes: simultaneous raising / lowering of all windows and raising / lowering a single window, which can better meet the user's need for simultaneous raising / lowering of all windows.

[0063] Generally, vehicles frequently fall into water unexpectedly. If all windows are closed and the user cannot issue a command to open them, escape may be impossible. To increase the user's chances of escape when a vehicle falls into water, step S21 generates a window raising / lowering command based on the window raising / lowering signal. This can include: determining whether a vehicle falling into water signal has been received; if a vehicle falling into water signal has been received, generating a window raising / lowering command to open the window; if no vehicle falling into water signal has been received, generating a window raising / lowering command based on the window raising / lowering signal. The vehicle falling into water signal can be detected by a wading sensor, and the window raising / lowering command to open the window can be a command to open a single window or a command to open multiple windows. This allows the user to escape through the opened window, increasing the chances of escape.

[0064] Considering that the water level of each window may be the same or different when a vehicle falls into water, if all windows are flooded simultaneously or none are flooded, the window closest to the user should be opened to reduce the time required for the user to escape through the window. In this case, step S21 generates a window raising / lowering command to control the opening of the window, including: generating a window raising / lowering command to control the opening of the window closest to the occupants when all windows of the vehicle are flooded simultaneously or none are flooded. When a vehicle falls into water, it may tilt, resulting in some windows being flooded while others are not. Opening a flooded window in this case would allow water to rush into the vehicle through that window, reducing the chances of escape for the occupants. Therefore, it is necessary to open the windows that are not flooded. In this case, step S21 generates a window raising / lowering command to control the opening of the window, including: generating a window raising / lowering command to control the opening of the windows that are not flooded when some windows of the vehicle are flooded and others are not.

[0065] like Figure 3 As shown, embodiments of the present invention also provide a window lifting control device applied to a motor, comprising:

[0066] The judgment module is used to determine whether the communication between the motor and the controller is valid after the vehicle is powered on;

[0068] And for controlling the raising and lowering of the windows based on the window raising and lowering signal after receiving the window raising and lowering signal from the window raising and lowering switch.

[0071] The control module can also be used to control the raising and lowering of car windows based on window raising and lowering commands.

[0072] like Figure 4 As shown, embodiments of the present invention also provide a window lifting control device for use with a controller, comprising:

[0073] The generation module is used to generate window lifting commands in response to the window lifting signal sent by the motor.

[0074] The second sending module is used to send window lifting commands to the motor so that the motor can control the window lifting based on the window lifting commands.

[0075] Furthermore, the generation module can be specifically used for:

[0076] If the window raising / lowering signal is a signal for all windows to be raised / lowered simultaneously, then obtain the power supply of the motor;

[0077] The window raising / lowering command is generated based on the window raising / lowering signal and the power supply.

[0078] The window raising and lowering command includes controlling the number of windows that can be raised and lowered simultaneously, and the number of windows is positively correlated with the power supply.

[0079] Furthermore, the generation module can also be used for:

[0080] If the power supply is higher than the preset threshold, a window raising / lowering command is generated based on the window raising / lowering signal, with the number of windows equal to the total number of all windows.

[0081] If the power supply is lower than the preset threshold, a window raising / lowering command with a window count of 1 will be generated based on the window raising / lowering signal.

[0082] Furthermore, the generation module can be specifically used for:

[0083] Determine if a vehicle has fallen into the water signal has been received;

[0084] If a signal indicating that a vehicle has fallen into water is received, a command to raise or lower the windows to control the opening of the windows is generated.

[0085] If no signal of the vehicle falling into water is received, a window raising / lowering command is generated based on the window raising / lowering signal.

[0086] Furthermore, the generation module can also be used for:

[0087] When all windows of the vehicle are submerged in water or none are submerged, a window raising / lowering command is generated to control the opening of the window closest to the occupants.

[0088] When some windows of the vehicle are submerged in water while others are not, a command is generated to raise or lower the windows of the unsubmerged windows.
