[0028] Furthermore, the embodiments and features described herein can be combined with each other, provided there is no conflict.

[0029] Figure 1 is a schematic diagram of an electric cup lid provided in an embodiment of the present invention. As shown in Figure 1, the electric cup lid mainly refers to the central control cup lid installed in a vehicle. Its structure includes a cup lid plate 1, a slide rail 2, a position switch 3, a Hall element 4, a worm gear 5, a gear 6, and a motor 7. The motor mainly refers to a Hall motor, which works by detecting the position and speed of the motor rotor through Hall elements, thereby controlling the motor's operation through Hall counting. The triggering of the position switch signal, combined with the Hall signal emitted by the Hall element, can be used to perform stroke calculation, zero-point calibration, and Hall pulse calculation for the electric cup lid.

[0030] Figure 2 is a flowchart of an electric cup lid control method provided by an embodiment of the present invention. This embodiment is applicable to the control of electric cup lids in vehicles. Specifically, the electric cup lid control method can be executed by an electric cup lid control device, which can be implemented by software and / or hardware and integrated into an electronic device. The electronic device includes, but is not limited to, a controller, a microcontroller, an on-board computer, or an electronic control unit (ECU).

[0031] As shown in Figure 2, the method specifically includes the following steps:

[0032] S110. When the motor starts, control the motor to drive the electric cup lid to move in the opening direction, and determine the zero point position and anti-pinch area during the process of the electric cup lid moving in the opening direction to the hard stop position.

[0033] In this embodiment, the panel position of the electric cup lid can be self-learned, thereby calibrating the absolute position of the electric cup lid panel. Specifically, when the motor starts, the electric cup lid motor can be driven to move along the slide rail, and the entire movement stroke is calibrated during its movement to determine the zero point position and the anti-pinch zone. The zero point position can be understood as the extreme positions at both ends, and the anti-pinch zone can be understood as the area with anti-pinch function. Under normal circumstances, the anti-pinch zone is located in the middle part, and the boundary between the anti-pinch zone and the non-anti-pinch zone is the stopping point. In the non-anti-pinch zones at both ends, the electric cup lid moves at a slower speed, usually in the stage of slow start or slow stop, while in the anti-pinch zone, the electric cup lid can move at a faster speed and detect in real time whether an object is pinched or obstructing the movement of the electric cup lid. During this process, the Hall pulse signal emitted by the Hall element can be combined to accurately determine the zero point position and the anti-pinch zone.

[0034] S120. In response to the operation command, based on the pulse width modulation signal with adjustable duty cycle, the motor is controlled to drive the electric cup lid to move in a specified direction, wherein the specified direction is the opening direction or the closing direction, and the electric cup lid has an anti-pinch function when moving in the anti-pinch area.

[0035] In this embodiment, the operation command can refer to the user-input command to control the electric cup lid, such as opening or closing the electric cup lid. The operation command can be input via screen soft switch, hard switch button, remote command via mobile app, or voice, and the electric cup lid can be moved forward or backward by the motor according to the operation command. During this process, the speed of the electric cup lid can be adjusted using a pulse width modulation (PWM) signal, for example, controlling the electric cup lid to slow down and stop when it reaches a stop point, which can avoid structural noise. Furthermore, by collecting Hall pulse signals and monitoring current fluctuations during motor movement, the anti-pinch function of the electric cup lid can be implemented. In some embodiments, based on current, position switch signals, and Hall pulse signals, overcurrent protection, overload protection, and Hall reset calibration of the electric cup lid can also be implemented.

[0036] Understandably, each time the motor starts, it can learn and judge the starting current, running current, and whether the Hall effect sensor is faulty. During this period, the slow-down function and soft-stop function of the electric cup lid are turned off.

[0037] This invention provides an electric cup lid control method that electrically opens or closes the centrally controlled cup lid. When the motor starts, it learns the zero-point position and anti-pinch zone, thereby accurately controlling the movement position of the electric cup lid during actual operation. An adjustable duty cycle pulse width modulation signal controls the movement of the electric cup lid in each zone, achieving accurate control and ensuring safety. Furthermore, anti-pinch and speed adjustment effectively reduce noise during the movement of the electric cup lid and minimize collisions within the mechanism itself.

[0038] In one embodiment, determining the zero point position and the anti-pinch zone during the process of the electric cup lid moving in the opening direction to the hard stop position includes: when the electric cup lid moves in the opening direction to the hard stop position and the opening position switch is triggered before moving to the hard stop position, determining the position where the motor is in a stall state as the zero point position; determining the position where the distance from the zero point position at both ends of the motor slide rail is a specified number of Hall pulses as the slow stop point, and determining the area between the two slow stop points as the anti-pinch zone.

[0039] Figure 3 is a schematic diagram of the key positions and areas during the movement of an electric cup lid according to an embodiment of the present invention. As shown in Figure 3, taking the case where the electric cup lid moves to the left as opening and to the right as closing as an example, in the self-learning process of the electric cup lid, the zero point position and anti-pinch area of ​​the stroke are first determined. When the motor starts, for example, when the vehicle is started with one-button start, IG ON, or the engine is ignited, the motor of the electric cup lid starts. The motor can drive the electric cup lid to move in the cup lid opening direction (to the left in Figure 3) until the opening position switch is triggered, and then continue to drive the electric cup lid to the hard stop point 1, where a stall occurs and it stops moving. The opening position switch can be connected to the processor through a hardware pin, so that when it is confirmed that the current trigger is the opening position switch, it can learn that the current movement direction is the opening direction, and the zero point position is successfully learned after a stall occurs. Similarly, for the closing case, the motor can drive the electric cup lid to move to the right until the closing position switch is triggered, and then continue to drive the electric cup lid to the hard stop point 2, where a stall occurs and it stops moving, and the zero point position is successfully learned. In addition, the position of a Hall pulse at a distance of a specified number (x, where x is a positive integer) from the two extreme positions can be set as the stop point. The area between the two stop points is the anti-pinch area. The anti-pinch function is not available in the non-anti-pinch area.

[0040] In one embodiment, the method further includes: real-time monitoring of the motor's operating current; and determining that the motor is in a stalled state when the operating current is the product of the starting current and a set percentage.

[0041] Specifically, each time the motor starts, it can learn the starting current and monitor the motor's operating current in real time. When the operating current is a set percentage of the starting current (e.g., 70%), it is determined that the motor is in a stalled state, the drive of the motor is stopped, stall protection is implemented, the motor is prevented from overheating, and the motor's service life is extended.

[0042] In one embodiment, controlling the motor to drive the electric cup lid to move in a specified direction includes: controlling the motor to drive the electric cup lid to move in a specified direction based on a pulse width modulation signal with an initial duty cycle; before controlling the motor to drive the electric cup lid to move to the anti-pinch area, adjusting the duty cycle of the pulse width modulation signal according to the real-time resistance and the Hall waveform of the motor, so that the electric cup lid reaches a first speed and passes through the anti-pinch area at the first speed; after controlling the motor to drive the electric cup lid to pass through the anti-pinch area, reducing the duty cycle of the pulse width modulation signal according to the real-time resistance and the Hall waveform of the motor, so that the electric cup lid reaches a second speed and moves to the zero position in the specified direction at the second speed.

[0043] Specifically, based on self-learning, the system can generate and adjust pulse width modulation (PWM) signals according to operation commands to control the motor driving the electric cup lid in a specified direction. It also features a soft-start / soft-stop function each time the electric cup lid opens and closes. For example, when the motor starts moving, it is driven with an initial duty cycle, which can be a preset or default value. Simultaneously, the system detects the current real-time resistance and the Hall waveform emitted by the motor. Based on the real-time resistance and the motor's Hall waveform, the system ensures the motor moves at a first speed. If the real-time resistance is high, the duty cycle of the PWM signal can be gradually increased. Based on this, the speed adjustment process is completed before the electric cup lid reaches the soft-stop point (entering the anti-pinch zone), and the subsequent movement speed remains constant at the first speed. When the electric cup lid reaches another soft-stop point (moving out of the anti-pinch zone), the PWM speed adjustment function can be activated again to gradually decelerate, eventually moving slowly to the second speed. This effectively reduces the noise impact when the electric cup lid stops moving.

[0044] In one embodiment, the vehicle voltage can also be detected, and a maximum duty cycle limit can be set accordingly. The duty cycle of the pulse width modulation signal is adjusted to always be less than the maximum duty cycle limit, thereby avoiding excessive noise during the opening or closing of the electric cup lid.

[0045] In one embodiment, during the process of controlling the motor to drive the electric cup lid to move in a specified direction, the method further includes: continuing to drive the electric cup lid to move for a fixed time after triggering the corresponding position switch, and clearing the Hall count of the motor to zero.

[0046] Specifically, after the position switch is triggered, the drive continues for a fixed duration (e.g., 0.5 seconds) to ensure that the electric cup lid actually moves to the extreme positions at both ends, that is, the electric cup lid is completely closed or opened. In this case, the drive motor can be stopped and the Hall count can be cleared, which can effectively avoid Hall offset after multiple movements.

[0047] In one embodiment, during the process of controlling the motor to drive the electric cup lid to move in a specified direction, the method further includes: when the electric cup lid is in the anti-pinch area, monitoring the operating current of the motor in real time in stages; in the first stage, if the operating current exceeds a first current threshold, the anti-pinch function is triggered; in the second stage, if the operating current exceeds a second current threshold, or the current change within a unit time period exceeds a third current threshold, the anti-pinch function is triggered; wherein, the second current threshold is higher than the first current threshold, and the first current threshold is higher than the third current threshold.

[0048] Specifically, for the anti-pinch function of electric cup lids, a segmented current monitoring strategy can be adopted to address the issue of false pinching caused by excessive current fluctuations during operation. For example, the operating current can be monitored in five segments. The first four segments have relatively stable operating currents, and the anti-pinch current threshold (i.e., the first current threshold) can be uniformly set to 'a' (unit: A). If the motor's operating current exceeds 'a' in the first four segments, the anti-pinch function will be triggered. The last segment has larger operating current fluctuations, and the anti-pinch current threshold (i.e., the second current threshold) can be set to 'b' (unit: A), for example, 1.8 times 'a'. If the motor's operating current exceeds 'b' in the last segment, the anti-pinch function will be triggered. Furthermore, considering the larger anti-pinch force in the last segment, the current change over a short period (e.g., 50ms) can be compared within the last segment. If the short-term current change exceeds the third current threshold, the anti-pinch function will be triggered. The third current threshold can be set to 'c' (unit: A), where c < a < b.

[0049] Based on this, according to the motor's operating current, when an object is detected being pinched, the motor can immediately stop moving in its original direction and retract (i.e., move in the opposite direction) a certain distance. Furthermore, during the anti-pinch retraction process, the motor's operating current can also be used to monitor whether an object is pinched; if the anti-pinch mechanism is triggered again, the motor can be directly stopped. Optionally, if the anti-pinch mechanism is triggered a set number of times (e.g., 3 times) before the motor reaches its limit position, the motor can stop driving and await manual operation by the user.

[0050] In one embodiment, during the process of controlling the motor to drive the electric cup lid to move in a specified direction, the method further includes: counting the number of times the trigger switch is activated by a counter; if the cumulative number reaches a preset number, the frequent operation protection function is triggered, and the operation command is not responded to within a preset time period;

[0051] The counting of the number of times the switch is triggered using a counter includes:

[0052] If the position switch is triggered multiple times within a specified time period, and the time interval between two consecutive triggers is less than the first time interval, the count value is incremented by 1; otherwise, the count value is decremented by 1.

[0053] If the time interval between controlling the motor to drive the electric cup lid to move in two directions is less than the second time interval, the count value is incremented by 1;

[0054] If the time interval between controlling the motor to drive the electric cup lid to move in two directions is greater than the third time interval, the count value is reduced by 2;

[0055] After the frequent operation protection function is triggered, if there is no operation for a set period of time, the count value will be decremented by 2 until the count value is reduced to 0.

[0056] Specifically, the frequent operation protection function can refer to the protection function set for situations where the electric cup lid is frequently operated (such as children's unconventional operation or accidental touch by the user). After the frequent operation protection function is triggered, the user's operation can be suspended or refused.

[0057] For example, if the position switch is triggered multiple times within a specified time period, such as 15 consecutive triggers within 30 seconds, the count is incremented by 1 if the time interval between two consecutive triggers is less than the first time interval (e.g., 2 seconds); the count is decremented by 1 if the time interval between two consecutive triggers is greater than or equal to the first time interval; if the cumulative number reaches a preset number (e.g., 30 times), the system enters a frequent operation protection state and takes the first frequent operation protection measure, such as not responding to any operation command within 10 seconds.

[0058] Optionally, after the frequent operation protection function is triggered, if there is no operation for a set interval (such as every 10 seconds), the count can be decremented by 2 until it is reduced to 0.

[0059] For example, if the time interval between the electric cup lid moving in two directions is less than the second time interval (e.g., 2 seconds), and the time interval between the motor's movements in two directions is less than 2 seconds, then the count is incremented by 1; if the time interval between the movements in two directions is greater than the third time interval (e.g., 20 seconds), then the count is decremented by 2; if the interval time is within the second and third time intervals (2 seconds to 20 seconds), then the count remains unchanged; if the cumulative number of times reaches 30, then the system enters the frequent operation protection state and takes the second frequent operation protection measure, such as not responding to any operation command within 20 seconds.

[0060] Optionally, the frequent operation protection can be deactivated when the count drops to 0, IG is turned off, or the motor is powered on again.

[0061] Figure 4 is a structural schematic diagram of an electric cup lid control device provided in an embodiment of the present invention. As shown in Figure 4, the electric cup lid control device provided in this embodiment includes:

[0064] When the motor starts, the device can learn the zero position and anti-pinch zone, so as to accurately grasp the movement position of the electric cup lid during actual operation.

[0080] In the second stage, if the operating current exceeds the second current threshold, or the current change within a unit time period exceeds the third current threshold, the second trigger module will trigger the anti-pinch function.

[0081] Among them, the second current threshold is higher than the first current threshold, and the first current threshold is higher than the third current threshold.
