Description

Technical Field

[0001] The present invention relates to the technical field of vehicle door and window control, and in particular to a control method, device, equipment and readable storage medium for a door and window lifter motor. Background Art

[0002] The travel of the door glass is fixed, and it usually takes no more than 10 seconds for the glass to rise from the bottom to the top. In actual use, the glass lifting function will not be used for a long time, so the door and window lift motor is designed for short-term, high-current, intermittent operation, and its heat dissipation capacity is not enough to support long-term continuous operation. If the glass is repeatedly raised and lowered in a high-temperature environment, there is a risk of the motor overheating and burning.

[0003] To eliminate this risk, in the prior art, the door and window lift motor is generally equipped with a built-in thermal protection switch. When the motor temperature is too high, the thermal protection switch is disconnected to protect the motor from burning.

[0004] However, when the prior art solution sets a thermal protection switch inside the motor for thermal protection, the thermal protection switch is relatively sensitive and easily affected by surrounding electromagnetic interference, electrostatic interference, etc., which may cause its thermal protection function to be abnormal. In addition, some door and window lifters have an anti-pinch function. When the glass is blocked by a human body or other objects during its rise, the lifter motor automatically reverses to lower the glass to avoid hurting people. However, when the glass is blocked by a human body, the operating time will inevitably increase, and the heat will increase. If the temperature of the motor is high before the glass rises (such as when the ambient temperature is high in summer or the glass has been repeatedly raised and lowered several times), the motor temperature may exceed the working temperature of the thermal protection switch when the glass is blocked. If the thermal protection switch is disconnected and the power is cut off at this time, the anti-pinch function will fail, causing danger. Summary of the invention

[0005] The embodiments of the present invention provide a control method, device, equipment and readable storage medium for a door and window lifter motor to solve the technical problem in the related art that the existing door and window lifter motor is thermally protected by setting a thermal protection switch, which is easily affected by surrounding electromagnetic interference, electrostatic interference, etc., resulting in abnormal thermal protection function.

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The embodiment of the present invention provides a control method for a door and window lifter motor, which can solve the technical problem that the existing door and window lifter motor is thermally protected by setting a thermal protection switch, which is easily affected by surrounding electromagnetic interference, electrostatic interference, etc., resulting in abnormal thermal protection function.

[0049] See also Figure 1 As shown, an embodiment of the present invention provides a method for controlling a door and window lifter motor, comprising the following steps:

[0050] Step S10, after the vehicle is powered on, the current allowed number of operations of the window lifter motor is determined according to the current temperature of the cockpit.

[0051] Specifically, after the vehicle is powered on, the vehicle controller can obtain the current temperature of the cockpit through a temperature sensor arranged in the cockpit.

[0052] The step of determining the current allowed number of operations of the window lifter motor according to the current temperature of the cockpit comprises:

[0053] Step S101, determining the current temperature compensation operation times according to the current temperature of the cockpit.

[0054] Step S102, summing the normal temperature allowed operation times and the current temperature compensation operation times to obtain the current allowed operation times.

[0055] Among them, the window lift motor reaches the upper limit of the allowed number of operations at normal temperature (23°C) can be recorded as N1. N1 is an inherent property of the motor and can be obtained through prior calibration. When the ambient temperature (cockpit temperature) of the window lift motor is different, the number of times the upper limit is allowed is different. The lower the temperature, the more the upper limit is allowed. Relative to normal temperature, the number of times the upper limit of the motor is allowed to run at different temperatures can be recorded as N2. When the ambient temperature is lower than normal temperature, N2 is a positive value. When the ambient temperature is higher than normal temperature, N2 is a negative value. When the ambient temperature is normal temperature, N2 is 0. N2 is also an inherent property of the motor and can be obtained through prior calibration.

[0056] Specifically, see Figure 3 As shown, the step of determining the current temperature compensation operation times according to the current temperature of the cockpit includes:

[0057] The current temperature compensation running times are determined according to a preset relationship curve between the temperature compensation running times and the temperature and the current temperature of the cockpit. Figure 3 In the figure, when the ambient temperature is lower than the normal temperature, N2 is a positive value; when the ambient temperature is higher than the normal temperature, N2 is a negative value; when the ambient temperature is the normal temperature, N2 is 0. The lower the temperature, the more times the compensation can be performed.

[0058] Step S20, determining the current equivalent operation times of the window lifter motor according to the current temperature of the cockpit and the current actual operation times and the current stop operation time of the window lifter motor.

[0059] Specifically, see Figure 4 As shown, the step of determining the current equivalent number of operations of the window lifter motor according to the current temperature of the cockpit and the current actual number of operations and the current stop time of the window lifter motor comprises:

[0060] Step S201, determining the current equivalent reduction times of the window lifter motor according to the current temperature of the cockpit and the current stop time of the window lifter motor.

[0061] Step S202, subtracting the current equivalent reduction times from the current actual operation times of the door and window lifter motor to obtain the current equivalent operation times of the door and window lifter motor.

[0062] When the window lift motor stops running, the motor temperature will gradually decrease during the stop time, and the speed of the motor temperature decrease will be different under different ambient temperatures. The window lift can increase the number of operations after stopping for a specific period of time. For example, assuming that the current equivalent reduction times of the window lift motor is N3, the current actual operation times of the window lift motor is N0, and the current equivalent operation times of the window lift motor is N=N0-N3. The window lift motor has built-in dual Hall sensors, which can determine the window lift operation stroke and door glass position in real time. The vehicle controller can determine whether the window lift motor has run once by reading this information, that is, the glass rises or falls more than 50% of the full stroke, so as to determine the current actual operation times of the window lift motor N0.

[0063] Step S30, judging whether the current equivalent operation times of the window lifter motor is less than the current allowed operation times. Specifically, judging whether the current equivalent operation times of the window lifter motor is less than the current allowed operation times, that is, comparing N0-N3 with N1+N2.

[0064] Step S40: If yes, determine that the door and window lifter motor is overheated, and control the door and window lifter motor to be powered off; if no, repeat the above steps S10 to S30 until the whole vehicle is powered off.

[0065] The control method of the window lift motor of the embodiment of the present invention, after the whole vehicle is powered on, firstly determines the current allowed number of operation of the window lift motor according to the current temperature of the cockpit; then determines the current equivalent number of operation of the window lift motor according to the current temperature of the cockpit and the current actual number of operation of the window lift motor and the current stop time; then determines whether the current equivalent number of operation of the window lift motor is less than the current allowed number of operation; finally determines whether the window lift motor is overheated according to the judgment result, and controls the window lift motor to cut off the power when it is determined that the window lift motor is overheated. That is, the embodiment of the present invention can realize the motor thermal protection through the logic control of the vehicle controller, without setting a thermal protection switch inside the motor, and will not be affected by the surrounding electromagnetic interference, electrostatic interference, etc., and the stability of the motor thermal protection function is good.

[0066] As an optional implementation, in an embodiment of the invention, see Figure 5 As shown, the step of determining the current allowed number of operations according to the current temperature of the cockpit includes:

[0067] Step S103, determining the current temperature compensation operation times according to the current temperature of the cockpit.

[0068] Step S104, summing the normal temperature allowed operation times, the current temperature compensation operation times and the reserved safety operation times to obtain the current allowed operation times.

[0069] Compared with the aforementioned method of summing the number of allowed operations at normal temperature and the number of operations with current temperature compensation to obtain the current number of allowed operations, in order to ensure that the anti-pinch function of the door and window lifter can be triggered normally, the embodiment of the present invention increases the number of reserved safe operations in the motor thermal protection. This reserved number of safe operations can be achieved by changing the current number of allowed operations. Generally, the reserved number of safe operations can be set to 2 times.

[0070] Furthermore, based on the above-mentioned reserved safe operation times, see Figure 6 As shown, if so, the step of determining that the door and window lift motor is overheated and controlling the door and window lift motor to be powered off includes:

[0071] Step S401, determine whether the door and window anti-pinch function is triggered. The anti-pinch function is triggered through touch and vision. The touch is when the door and window lifter senses a foreign object, the current sensor (Hall sensor) set in the door and window lifter is activated and triggered, and the information is sent to the vehicle controller. The vision is monitored by the optical system. The optical system will detect whether there is a foreign object within the range of the window movement and send information to the vehicle controller.

[0072] Step S402: If yes, first control the door and window lift motor to reverse a preset number of turns, then control the door and window lift motor to cut off power, and generate an alarm message of overheating of the door and window lift motor and send it to the instrument panel for display.

[0073] On the basis of the above-mentioned reserved safe operation times, the embodiment of the present invention reserves 2 motor operations. When the door and window anti-pinch function is triggered, the door and window lifter motor is controlled to reverse the preset number of turns, and then the door and window lifter motor is controlled to be powered off. Compared with the existing thermal protection switch, the embodiment of the present invention can ensure the normal implementation of the anti-pinch function. In addition, after determining that the door and window lifter motor is overheated, the embodiment of the present invention generates an alarm message of the door and window lifter motor overheating and sends it to the instrument panel for display, which can give the driver a corresponding alarm reminder.

[0074] As an optional implementation, in an embodiment of the invention, see Figure 7 As shown, the step of determining the current equivalent reduction times of the window lifter motor according to the current temperature of the cockpit and the current stop time of the window lifter motor comprises:

[0075] Step S2011, determining the calculation coefficient of the current equivalent reduction times per unit time according to the current temperature of the cockpit.

[0076] Step S2011, dividing the current stoppage time of the door and window lifter motor by the calculation coefficient and rounding down to obtain the current equivalent reduction times.

[0077] Specifically, after the door and window lift motor stops running for a period of time, the door and window lift motor can increase the number of operations. The stop time and ambient temperature requirements required for each additional operation are shown in Table 1 below:

[0078] Table 1

[0079] Temperature range / ℃ -40～-20 -21～0 1～+20 +21～+40 +41～+60 t / min 1 2 3 5 10

[0080] Under the current ambient temperature conditions, the window lift motor can increase the number of operations by one every time the stop operation time reaches the above time requirement. The additional number of operations generated by the stop operation time is counted as N3. It can be seen that N3 = stop operation time / t (rounded down), and t is the calculation coefficient of the current equivalent reduction number per unit time. It should be noted that N3 returns to zero after each operation of the window lift, and re-enters the stop operation time determination.

[0081] It should be noted that in the actual application of the control method of the door and window lifter motor of the embodiment of the present invention, if the door and window lifter motor is not overheated and powered off after the vehicle is powered on, the above steps S10 to S40 are executed cyclically at intervals of a certain period. In order to ensure the accuracy of determining whether the door and window lifter motor is overheated, in the process of executing the above steps after the vehicle is powered on, it is also necessary to consider the equivalent number of operations of the vehicle when it was powered off last time and the time when the door and window lifter motor stopped running between the last power off and the current power on of the vehicle, and convert it into an initial number of operations of the door and window lifter motor in a manner similar to the above step S201 and add it to the current actual number of operations of the door and window lifter motor N0. Of course, if the time is too long, based on the above analysis, the equivalent number of operations of the door and window lifter motor when it was powered off last time can be ignored (if the time is too long, the number of operations of the door and window lifter motor is equivalent to zero).

[0082] See also Figure 8 As shown, an embodiment of the present invention further provides a control device for a door and window lifter motor, comprising a vehicle controller, wherein the vehicle controller comprises: a first determining unit, a second determining unit, a judging unit and a control unit.

[0083] The first determination unit is used to determine the current allowed number of operations of the window lifter motor according to the current temperature of the cockpit after the vehicle is powered on.

[0084] The second determining unit determines a current equivalent number of operations of the window lifter motor according to a current temperature of the cockpit and a current actual number of operations and a current stop time of the window lifter motor.

[0085] The judging unit is used to judge whether the current equivalent operation times of the door and window lifter motor is less than the current allowed operation times.

[0086] The control unit is used to determine if the door and window lifter motor is overheated and control the door and window lifter motor to be powered off; if yes, determine if the door and window lifter motor is overheated and control the door and window lifter motor to be powered off; if no, repeat the determination and judgment process of the first determination unit, the second determination unit and the judgment unit until the entire vehicle is powered off.

[0087] In the control device of the window lift motor in the embodiment of the present invention, after the whole vehicle is powered on, the first determination unit of the vehicle controller first determines the current allowed number of operations of the window lift motor according to the current temperature of the cockpit; the second determination unit of the vehicle controller then determines the current equivalent number of operations of the window lift motor according to the current temperature of the cockpit and the current actual number of operations of the window lift motor and the current stop operation time; the judgment unit of the vehicle controller then judges whether the current equivalent number of operations of the window lift motor is less than the current allowed number of operations; the control unit of the vehicle controller finally determines whether the window lift motor is overheated according to the judgment result, and controls the window lift motor to cut off the power when it is determined that the window lift motor is overheated. That is, the embodiment of the present invention can realize motor thermal protection through the logic control of the vehicle controller, without setting a thermal protection switch inside the motor, and will not be affected by surrounding electromagnetic interference, electrostatic interference, etc., and the stability of the motor thermal protection function is good.
