Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of motor overheating protection, and specifically to an overheating protection method, device and system for a motor of a vehicle-mounted lifting bracket. Background Art

[0002] As wireless charging technology matures and becomes more popular, more and more vehicles are equipped with wireless charging panels in the front row. The structure generally fixes the wireless charging module on the back of the charging panel. When the smart terminal is detected to be placed on the charging panel, the vehicle-mounted lifting bracket motor drives the charging panel and the wireless charging module to the lowest position for wireless charging; when the smart terminal is detected to leave the charging panel, the vehicle-mounted lifting bracket motor drives the charging panel and the wireless charging module to rise to the highest design position.

[0003] However, during use, frequent picking up and putting down of the smart terminal will cause the motor of the vehicle lift bracket to rise and fall repeatedly, causing the motor of the vehicle lift bracket to overheat, affecting the charging efficiency of the wireless charging module. In order to provide overheat protection in time, the commonly used method is to set a sensor on the motor of the vehicle lift bracket to detect the number of movements of the motor of the vehicle lift bracket, and trigger the overheat protection when the number of movements meets the protection condition.

[0004] However, the currently commonly used methods have the following technical problems: once the motor of the vehicle-mounted lifting bracket stops running, its temperature will gradually decrease. Therefore, the overheating protection is triggered only by the number of movements. The detected overheating protection state deviates from the actual state. Not only is the control accuracy of the overheating protection low, but the false triggering will affect user use and reduce the user experience. Summary of the invention

[0033] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0034] Figure 1 A schematic flow chart of a first embodiment of an overheating protection method for a motor of a vehicle-mounted lifting bracket provided by the present invention is shown. The method is executed by an overheating protection device for a motor of a vehicle-mounted lifting bracket.

[0035] In one embodiment, the overheat protection device of the vehicle-mounted lifting bracket motor may be a vehicle body domain controller (BDC). The body domain controller (BDC) may be connected to the vehicle-mounted lifting bracket motor and the wireless charging module respectively, and detect whether there is a smart terminal for wireless charging through the wireless charging module. If so, the lifting of the vehicle-mounted lifting bracket motor may be controlled.

[0036] like Figure 1 As shown, the method comprises the following steps:

[0037] Step 110: collecting time parameters of the motor of the vehicle-mounted lifting support, wherein the time parameters include: the running time of each movement of the motor of the vehicle-mounted lifting support and the downtime time of each stop movement.

[0038] In one embodiment, the time parameters of the motor of the vehicle-mounted lifting support may be obtained after the vehicle is started, and the time parameters include: the running time of each movement of the motor of the vehicle-mounted lifting support and the stopping time of each stop movement.

[0039] Among them, the running time is the total time that the motor of the vehicle-mounted lifting bracket moves continuously from starting to stopping. The downtime is the total time that the motor of the vehicle-mounted lifting bracket stops.

[0040] If the running time is short, the heat generated by the vehicle-mounted lifting bracket motor is small, and thermal protection may not be performed; similarly, if the downtime is long, the vehicle-mounted lifting bracket motor can dissipate more heat, and thermal protection may not be performed.

[0041] Before collecting time parameters, you need to determine the status of the vehicle and the vehicle-mounted lifting bracket motor. If the vehicle or the vehicle-mounted lifting bracket motor is abnormal, you can first deal with the abnormality and then perform overheat protection.

[0042] As an example, the step of collecting the time parameters of the motor of the vehicle-mounted lifting bracket may include the following steps:

[0043] Step 1101: When it is determined that the vehicle is powered on, the motor of the vehicle lift bracket has not fed back a fault state, the motor of the vehicle lift bracket is in a normal initialization state, and the motor of the vehicle lift bracket is in a moving state or in a stationary state, collect time parameters;

[0044] The fault state includes one or more of an open circuit fault, a voltage fault and a system fault.

[0045] Specifically, it can determine whether the vehicle is in a powered-on state (specifically, the body domain controller (BDC) feedbacks that the vehicle power is in the ON gear or the vehicle is powered on), whether the vehicle-mounted lifting bracket motor feedbacks a fault state, whether the initialization state of the vehicle-mounted lifting bracket motor is normal, and whether the vehicle-mounted lifting bracket motor is in motion or in a stationary state.

[0046] If it is determined that the vehicle is powered on, the motor of the vehicle lift bracket has not fed back a fault state, the initialization state of the motor of the vehicle lift bracket is normal, and the motor of the vehicle lift bracket is in motion or in a stationary state, then the time parameters can be collected.

[0047] In one embodiment, the fault state fed back by the motor of the vehicle-mounted lifting bracket may include: one or more of an open circuit fault, a voltage fault, and a system fault. When the motor of the vehicle-mounted lifting bracket feeds back any fault state, the time parameter is not collected.

[0048] When the vehicle is powered on normally and the motor of the vehicle-mounted lifting bracket is in normal condition, the collected time parameters are more objective, and subsequent evaluation and analysis can be accurately performed based on the time parameters to determine whether overheating protection is required.

[0049] Step 120: Calculate the total number of movements according to the time parameter and a preset statistical number of times, wherein the preset statistical number of times is the cumulative number of movements and stops of the motor of the vehicle-mounted lifting bracket after completing an overheat protection.

[0050] In one embodiment, whether the current movement or stillness can be counted can be determined based on the length of the time parameter. If it can be counted, the counted value and the preset statistical number value are used to calculate the total movement value of the vehicle-mounted lifting bracket motor. Finally, it is determined whether to perform overheating protection based on the total movement value of the vehicle-mounted lifting bracket motor to improve the accuracy of triggering protection.

[0051] The preset statistical number value is the cumulative number of movements and stops of the motor of the vehicle-mounted lifting bracket after completing an overheat protection.

[0052] In specific operation, when the vehicle-mounted lifting bracket motor completes an overheat protection, its previous movement times and stop times can be cleared and then counted from 0. Then the different accumulations are made until the overheat protection is triggered again.

[0053] In one embodiment, the preset statistical times values ​​include motion statistical values ​​and stop statistical values.

[0054] Specifically, the movement statistics value is the total number of movement times accumulated from the time node after the vehicle-mounted lifting bracket motor completes an overheating protection to the current time node; the stop statistics value is the total number of stop times accumulated from the time node after the vehicle-mounted lifting bracket motor completes an overheating protection to the current time node.

[0055] As an example, the step of calculating the total number of movements according to the time parameter and the preset statistical number of movements may include the following steps:

[0056] Step 1201: If the downtime is less than the preset clearing time, the running time and the movement statistics are used to calculate the corresponding movement times, and the downtime and the stop statistics are used to calculate the corresponding stop times.

[0057] It can be determined whether the downtime is less than the preset reset time. If the downtime is less than the preset reset time, it means that the motor of the vehicle lift bracket is stationary for a short time and the heat dissipation is small, so motion counting is required. On the contrary, if the downtime is greater than or equal to the preset reset time, it means that the motor of the vehicle lift bracket is stationary for a long time and the heat dissipation is large, so motion counting is not required.

[0058] Specifically, if the downtime is less than the preset clearing time, motion counting is required, and the corresponding motion count value can be calculated using the running time and the motion statistics, and the corresponding downtime value can be calculated using the downtime and the stop statistics.

[0059] Step 1202: Calculate the sum of the movement times and the shutdown times to obtain a total movement value.

[0060] Finally, the movement count value and the stop count value can be added together to get the total movement count value.

[0061] Specifically, the total number of movements can be expressed as follows:

[0062] EPPC=EPPC x+1 +EPPC y+1 .

[0063] Among them, EPPC is the total number of exercises, EPPC x+1 is the exercise frequency value, EPPC y+1 is the number of downtimes.

[0064] In order to accurately combine the length of the running time and the previously counted sports statistics to calculate the corresponding sports number value, as an example, the use of the running time and the sports statistics to calculate the corresponding sports number value may include the following steps:

[0065] Step 210: Calculate the ratio of the running time to the preset first time interval and take the integer to obtain the motion ratio.

[0066] Step 220: After calculating the product of the motion ratio and the preset motion coefficient to obtain the motion product value, the sum of the motion product value and the motion statistical value is calculated to obtain the motion count value.

[0067] Specifically, the ratio of the running time to the preset first time interval can be calculated first. If the ratio is an integer, the ratio is used as the motion ratio. If the ratio is not an integer, the determined integer can be rounded to the motion ratio.

[0068] Among them, the preset first time interval can be adjusted according to actual needs. If the movement frequency of the vehicle-mounted lifting bracket motor is high, the duration of the preset first time interval can be appropriately reduced. Conversely, if the movement frequency of the vehicle-mounted lifting bracket motor is low, the duration of the preset first time interval can be appropriately increased.

[0069] Step 220: After calculating the product of the motion ratio and the preset motion coefficient to obtain the motion product value, the sum of the motion product value and the motion statistical value is calculated to obtain the motion count value.

[0070] Specifically, after calculating the product of the motion ratio and the preset motion coefficient to obtain the motion product value, the motion product value and the motion statistical value are summed to obtain the motion count value.

[0071] In an operation example, the formula for the exercise number value can be shown as follows:

[0072] EPPC x+1 =2*[Tx / 0.7]+EPPC x .

[0073] Among them, EPPC x+1 is the number of exercises; EPPC x is the motion statistic value; 2 is the preset motion coefficient; 0.7 is the duration of the preset first time interval, in seconds; Tx is the running time, in seconds.

[0074] It should be noted that when rounding, the integer can be rounded up or down, preferably, the motion ratio can be rounded down to obtain the motion ratio. For example, the running time Tx is 1.5 seconds, the preset first time interval is 0.7, and the motion ratio is 2.14…5, which can be rounded to 2 to obtain the motion ratio.

[0075] Wherein, as an example, the use of the downtime and the stop statistics to calculate the corresponding downtime value may include the following steps:

[0076] Step 310: Calculate the ratio of the downtime to the preset second time interval and take the integer to obtain a downtime ratio.

[0077] Step 320: Calculate the difference between the stop ratio and the stop statistic value to obtain the stop count value.

[0078] Specifically, the ratio of the downtime to the preset second time interval may be calculated and rounded to an integer to obtain the downtime ratio. The rounding may be rounded to a larger integer or a smaller integer. Preferably, the downtime ratio may be rounded to a smaller integer.

[0079] Finally, the difference between the shutdown ratio and the stop statistics is calculated to obtain the shutdown times.

[0080] Specifically, the formula for the shutdown times value can be shown as follows:

[0081] EPPC y+1 =[Ty / 0.7]+EPPC y .

[0082] Among them, EPPC y+1 is the number of shutdowns; EPPC yis the stop statistic value; 0.7 is the duration of the preset second time interval, in seconds; Ty is the downtime, in seconds.

[0083] In an optional embodiment, the downtime may be greater than or equal to the preset clearing time, indicating that the motor of the vehicle-mounted lifting bracket is stationary for a long time, the heat dissipation is large, and the movement counting may not be performed. In order to adjust the previous movement times and stop times, as an example, the calculation of the total movement value according to the time parameter and the preset statistical number value may also include the following steps:

[0084] Step 1203: If the downtime is greater than or equal to the preset reset time, the movement times and the downtime times are reset, and the time parameters of the vehicle-mounted lifting bracket motor are re-collected.

[0085] Specifically, if the downtime is greater than or equal to the preset reset time, the movement times and the downtime times can be reset, and after reset, the time parameters of the vehicle-mounted lifting bracket motor are collected again and counted again.

[0086] In one operation mode, assuming that the downtime is 10 seconds and the preset zeroing time is 6 seconds, if the downtime is greater than or equal to the preset zeroing time, both the movement times value and the downtime times value can be reset to 0.

[0087] Step 130: When the total movement value is greater than or equal to the overheat protection threshold and the motor of the vehicle-mounted lifting bracket is at the bottom position, overheat protection is performed on the motor of the vehicle-mounted lifting bracket.

[0088] After the total movement value is calculated, it can be determined whether the total movement value is greater than or equal to the overheat protection threshold (assuming 50 times), and it can also be determined whether the vehicle-mounted lifting bracket motor is in the bottom position.

[0089] If the total motion value is greater than or equal to the overheat protection threshold and the vehicle lift motor is in the bottom position, the vehicle lift motor may be overheat protected.

[0090] If the total movement value is less than the overheat protection threshold or the vehicle lift bracket motor is in the top position, overheat protection may not be performed.

[0091] If the motor of the vehicle lift stand is not at the bottom position, it means that there is no smart terminal to charge temporarily. The motor of the vehicle lift stand can maintain the current position to continuously dissipate heat, and heat dissipation protection can be temporarily not performed.

[0092] When the motor of the vehicle lifting bracket is overheated, the driver can be reminded in time to prevent the driver from repeatedly triggering the movement of the motor of the vehicle lifting bracket. As an example, the overheating protection of the motor of the vehicle lifting bracket can include the following steps:

[0093] Step 1301: Stop sending motion instructions to the motor of the vehicle-mounted lifting bracket within a preset protection time, and control the central domain control module of the vehicle to display protection information to the user, so that the motor of the vehicle-mounted lifting bracket is stationary at the bottom position.

[0094] Specifically, the body domain controller (BDC) can stop sending motion instructions to the vehicle-mounted lifting bracket motor within a preset protection time (assuming 1 second), thereby controlling the vehicle-mounted lifting bracket motor to remain stationary at the bottom position. At the same time, it can control the vehicle's central domain control module to display protection information to the user to notify the user that the vehicle-mounted lifting bracket motor is overheated and protected and the vehicle-mounted lifting bracket motor is temporarily unavailable.

[0095] In specific operations, the central domain control module can display protection reminder information on the vehicle's screen.

[0096] After the overheat protection is completed, in order to allow the user to call the vehicle-mounted lifting bracket motor again in time, as an example, after the step of overheating protection of the vehicle-mounted lifting bracket motor, the method may further include the following steps:

[0097] Step 140: When the time that the vehicle-mounted lifting bracket motor remains stationary at the bottom position exceeds the preset protection time, if the wireless charging module of the vehicle-mounted lifting bracket motor detects that there is no smart terminal for wireless charging, it resumes sending motion instructions to the vehicle-mounted lifting bracket motor.

[0098] Specifically, when the time when the motor of the vehicle lifting bracket is stationary at the bottom position exceeds the preset protection time (assuming that it exceeds 1 second), if the motor of the vehicle lifting bracket is at the bottom position, the wireless charging module detects that there is no smart terminal for wireless charging temporarily, and the body domain controller (BDC) can resume sending motion instructions to the motor of the vehicle lifting bracket, and the body domain controller (BDC) can send motion instructions to the motor of the vehicle lifting bracket, so that the motor of the vehicle lifting bracket is reset to the top position, so that the user can put the smart terminal on the charging panel for wireless charging.

[0099] The present invention can collect the operating time and downtime of the motor of the vehicle-mounted lifting bracket; calculate the total movement value according to the operating time and downtime; and then trigger overheating protection in combination with the size of the total movement value and the position of the motor of the vehicle-mounted lifting bracket. Compared with the prior art that only triggers overheating protection by detecting the number of movements of the motor of the vehicle-mounted lifting bracket through a sensor, the present invention not only calculates the number of movements more accurately, but also can perform overheating protection in accordance with the actual use of the motor, which can improve the control accuracy of the overheating protection, avoid false triggering, and effectively improve the user experience.

[0100] Figure 2 The flowchart of the second embodiment of the overheat protection method of the motor of the vehicle-mounted lifting support provided by the present invention is shown, and the method is executed by the overheat protection device of the motor of the vehicle-mounted lifting support. Figure 2 As shown, the method comprises the following steps:

[0101] The first step is to determine that the body domain controller (BDC) feedbacks that the vehicle power supply is in the ON gear (the vehicle is powered on), that the vehicle lift bracket motor does not feedback the open circuit fault state, that the vehicle lift bracket motor does not feedback the voltage fault state, that the vehicle lift bracket motor does not feedback the system fault state, that the vehicle lift bracket motor initialization state is normal, and that the vehicle lift bracket motor is in motion or in a stationary state, so as to collect the operating time and downtime of the vehicle lift bracket.

[0102] In the second step, if the downtime is less than the preset clearing time (assuming 6 seconds), the movement times value is calculated according to the running time (optionally, it can be counted by a counter after calculation), and the stop times value is calculated according to the downtime (optionally, it can also be counted by a counter after calculation). If the downtime is greater than or equal to the preset clearing time (assuming 6 seconds), the movement times value and the stop times value are cleared.

[0103] The third step is to calculate the sum of the movement times and the shutdown times to obtain the total movement value. If the total movement value is greater than or equal to the preset statistical times (assuming 50 times), it is determined that the vehicle-mounted lifting bracket motor is at the bottom position; if the total movement value is less than the preset statistical times, return to the first step.

[0104] In the fourth step, if the motor of the vehicle lifting bracket is at the bottom position, the body domain controller (BDC) can send an overheat protection signal to the central domain controller (CDC) of the vehicle, so that the central domain controller can provide a text prompt on the vehicle screen, and the central domain controller (CDC) stops sending motion instructions to the motor of the vehicle lifting bracket. If the motor of the vehicle lifting bracket is not at the bottom position, return to the first step.

[0105] Figure 3The structure diagram of the first embodiment of the overheat protection device for the motor of the vehicle-mounted lifting bracket provided by the present invention is shown. Figure 3 As shown, the device 300 includes a parameter acquisition module 310 , a value calculation module 320 and an overheat protection module 330 .

[0108] The overheat protection module is used to perform overheat protection on the motor of the vehicle-mounted lifting bracket when the total movement value is greater than or equal to the overheat protection threshold and the motor of the vehicle-mounted lifting bracket is at the bottom position.

[0109] In an optional manner, the preset statistical number value includes a motion statistical value and a stop statistical value; and the calculating the total motion value according to the time parameter and the preset statistical number value includes:

[0110] If the downtime is less than the preset clearing time, the running time and the movement statistics are used to calculate the corresponding movement times, and the downtime and the stop statistics are used to calculate the corresponding stop times;

[0112] In an optional manner, the using the running time and the motion statistics to calculate the corresponding motion times value includes:

[0113] Calculate the ratio of the running time to the preset first time interval and take the integer to obtain a motion ratio;

[0114] After calculating the product of the motion ratio and the preset motion coefficient to obtain the motion product value, the sum of the motion product value and the motion statistical value is calculated to obtain the motion count value.

[0115] In an optional manner, the using the downtime and the stop statistics to calculate the corresponding downtime count value includes:

[0116] Calculate the ratio of the downtime to the preset second time interval and take the integer to obtain a downtime ratio;

[0117] The difference between the shutdown ratio and the stop statistic value is calculated to obtain the shutdown number value.

[0118] In an optional manner, the calculating the total number of movements according to the time parameter and a preset statistical number of times also includes:

[0119] If the downtime is greater than or equal to the preset reset time, the movement times and the downtime times are reset, and the time parameters of the motor of the vehicle-mounted lifting bracket are collected again.

[0120] In an optional manner, the overheat protection of the motor of the vehicle-mounted lifting bracket includes:

[0121] Stop sending motion instructions to the vehicle-mounted lifting bracket motor within the preset protection time, and control the vehicle's central domain control module to display protection information to the user, so that the vehicle-mounted lifting bracket motor is stationary at the bottom position.

[0122] In an optional manner, the device further includes:

[0123] The recovery sending instruction module is used to resume sending motion instructions to the vehicle-mounted lifting bracket motor after the step of overheating protection of the vehicle-mounted lifting bracket motor, when the vehicle-mounted lifting bracket motor is stationary at the bottom position for more than a preset protection time, if the wireless charging module of the vehicle-mounted lifting bracket motor detects that there is no smart terminal for wireless charging.

[0124] In an optional manner, the collecting of time parameters of the motor of the vehicle-mounted lifting bracket includes:

[0125] When it is determined that the vehicle is in a powered-on state, when it is determined that the motor of the vehicle lift bracket has not fed back a fault state, when it is determined that the initialization state of the motor of the vehicle lift bracket is normal, and when it is determined that the motor of the vehicle lift bracket is in a moving state or in a stationary state, the time parameters are collected;

[0126] The fault state includes one or more of an open circuit fault, a voltage fault and a system fault.

[0127] Figure 4 FIG. 1 is a schematic structural diagram of a first embodiment of an overheat protection system for a motor of a vehicle-mounted lifting bracket provided by the present invention. Figure 4 As shown, the overheat protection system of the vehicle-mounted lifting bracket motor may include: a vehicle screen, a central domain controller, a body domain controller, a vehicle-mounted lifting bracket motor, a charging panel, and a wireless charging module;

[0128] The vehicle screen, the central domain controller and the body domain controller are connected in sequence, the vehicle-mounted lifting bracket motor, the charging panel and the wireless charging module are connected in sequence, and the body domain controller is connected to the vehicle-mounted lifting bracket motor and the wireless charging module respectively;

[0129] The vehicle body domain controller is applicable to the overheat protection method for the motor of the vehicle-mounted lifting bracket as described in the above embodiment.

[0130] In actual operation, the body domain controller can send motion instructions through the LIN bus to start the vehicle lift bracket motor to move. At the same time, the open circuit fault flag, voltage fault flag, system fault flag, motor initialization status, motor motion status and motor position signal of the vehicle lift bracket motor can also be fed back to the body domain controller through the LIN bus. The body domain controller can determine whether the vehicle lift bracket motor is in motion based on the feedback LIN signal. If so, it can record the motion time and cumulative motion counter. When the body domain controller detects that the motion counter exceeds the threshold, the body domain controller triggers the thermal protection flag of the vehicle lift bracket motor and sends an overheating protection signal to the central domain controller. The central domain controller drives the vehicle screen to give a textual prompt. At the same time, the body domain controller stops sending motion instructions to the vehicle lift bracket motor, and the vehicle lift bracket motor remains stationary at the lowest position.

[0131] When the thermal protection of the vehicle lifting bracket motor is triggered 1 second later, the charging panel is at the lowest position, and the wireless charging module detects that there is no wireless charging mobile phone, the body domain controller clears the thermal protection flag and can resume sending motion instructions to the vehicle lifting bracket motor.
