[0044] As described in the background technology, the existing opening and closing methods of external interfaces still need to be improved. This is because: the pressing method is usually a mechanical structure, and a single press can achieve the unlocking / locking operation of the external interface (such as the cover), but it cannot meet the modern car buyers' demand for a "high-tech feel" in cars; and the button method mainly controls the opening and closing of the cover through a button switch combined with a cover opening motor, which has a certain sense of technology, but requires reserving a button position, which will affect the appearance of the entire vehicle to a certain extent.

[0045] In order to solve the above technical problems, the present disclosure provides a control component, which can be applied to a car, and the control component can include a control device, a trigger device and a controller. When the trigger device is triggered, the electrical parameters of the trigger device can change, so the controller can generate a touch signal based on the electrical parameter change. Under the action of the touch signal, the driving device can generate a driving force to control the operation process of the control device. The control device is arranged on the car, so at least two different operations can be performed on the car (for example, opening or closing the door, opening or closing the fuel filler cover, or opening or closing the charging cover, etc.). In this way, there is no need to press or press buttons. When the trigger device is touched, the corresponding operation can be performed on the car, thereby improving the simplicity of car operation and further improving user experience.

[0046] And since there is no need to reserve space for buttons, it will not affect the overall appearance of the car, further improving the user experience.

[0047] In order to enable those skilled in the art to better understand and implement the present disclosure, the specific schemes, principles, advantages, effects, etc. of the present disclosure are described in detail through specific embodiments with reference to the accompanying drawings.

[0048] In some embodiments of the present disclosure, see Figure 1 A schematic diagram of the structure of a control component in an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the control assembly 100 can be applied to a car ( Figure 1 (not shown) to perform corresponding operations on the car (such as opening or closing the door, opening or closing the fuel door, or opening or closing the charging door, etc.). In this case, Figure 1 As shown, the control assembly 100 may include:

[0049] A control device 110 is provided on the vehicle, and the control device 110 includes at least two different control states;

[0050] The trigger device 120 is disposed on the control device 110 and is electrically connected to the vehicle, and when the trigger device 120 is touched, the electrical parameters of the trigger device 120 change;

[0051] The controller 130 is disposed on the vehicle and is electrically connected to the trigger device 120 , and is used to generate a touch signal based on a change in an electrical parameter of the trigger device 120 ;

[0052] The driving device 140 is disposed on the vehicle and is electrically connected to the controller 130 and the control device 110 , and is used to generate a driving force based on the touch signal to control the control state of the control device 110 .

[0053] Specifically, when the trigger device 120 is not touched, it means that the vehicle has not been subjected to any operation related to the trigger device 120 , and there is no need to trigger the control device 110 , and further, there is no need to perform any corresponding operation on the vehicle.

[0054] When the trigger device 120 is touched, it means that at least one of the operations needs to be performed on the car. At this time, the electrical parameters of the trigger device 120 are different from the electrical parameters when it is not triggered, that is, the electrical parameters of the trigger device 120 change. At this time, the controller 130 can receive the change in the electrical parameters, and then generate a corresponding touch signal. Under the action of the touch signal, the driving device 140 can generate a driving force, and then can control the operation process of the control device 110. Since the control device is set on the car, the corresponding operation can be performed on the car (for example, opening or closing the door, opening or closing the fuel filler cover, or opening or closing the charging cover, etc.). In this way, there is no need to press or press buttons. When the trigger device 120 is triggered, the corresponding operation can be performed on the car, thereby improving the simplicity of car operation and thus improving user experience.

[0055] It should be noted that, first, Figure 1 The relative positions of the control device and the trigger device shown are only examples, which are used to indicate that the trigger device can be set on the control device and should not be understood as a limitation of the present invention; second, the "trigger device being triggered" referred to in the embodiment of the present disclosure may refer to the entity directly contacting the trigger device, or may refer to a short distance between the entity and the trigger device, and the trigger device is triggered through the induction effect; third, no examples are provided for the functions implemented by the existing solutions in the control component; fourth, the control device, the controller and the drive device may be existing structures on the car. The present invention performs corresponding operations on the car by additionally setting a trigger device and linking it with the control device, the controller and the drive device.

[0056] In some embodiments of the present disclosure, the electrical parameter may refer to a capacitance parameter, and whether the trigger device is triggered may be determined based on a change in the capacitance parameter of the trigger device.

[0057] In some embodiments, the trigger device has a parasitic capacitance. When the trigger device is triggered, a touch capacitance is generated on the trigger device, and the characteristics of the touch capacitance corresponding to different media are different.

[0058] Specifically, see Figure 2 The trigger principle diagram of a trigger device in an embodiment of the present disclosure is shown in FIG. Figure 2 As shown, when the trigger device 120 is connected to the power supply circuit of the car, a parasitic capacitance Cp will be generated in the power supply circuit due to the characteristics of the trigger device 120 itself; and when the trigger device 120 is triggered, it will affect the overall capacitance of the trigger device 120, making the overall capacitance of the trigger device 120 larger. For example, when the trigger device 120 is triggered, the overall capacitance of the trigger device 120 increases the touch capacitance Ct, so that the state of the trigger device 120 can be determined based on the capacitance change of the trigger device 120.

[0059] Furthermore, combined with the performance of the trigger device 120 itself, the influence of the parasitic capacitance Cp can be effectively reduced, so that the touch capacitance Ct can be detected more effectively, the accuracy of the touch signal can be improved, and false touches can be prevented.

[0060] It should be noted that Figure 2 The illustrated structure of the trigger device 120 is for illustrative purposes only and is used to illustrate the capacitance change when the trigger device 120 is triggered and not triggered, and should not be construed as a limitation to the present invention.

[0061] In actual application, the inventors further discovered that for different media (eg, rain, snow, or people), when the trigger device is triggered, the characteristics of the touch capacitors corresponding to the different media are different.

[0062] Considering that the trigger device is generally located outside the car, there are situations where the trigger device is triggered by different media, and some situations need to be avoided. Therefore, it is possible to further determine whether the touch capacitance is biological capacitance (that is, the capacitance caused by human touch) or capacitance caused by other objects, thereby more accurately identifying human touch signals.

[0063] In other words, the controller may be configured to generate a touch signal when the characteristic of the touch capacitance is a preset characteristic.

[0064] In some optional examples, the controller may be configured to determine whether the characteristic of the touch capacitance is a preset characteristic according to an initial slope of a signal change curve corresponding to the touch capacitance.

[0065] Specifically, if it is the capacitance caused by human touch, the capacitance value is constant within a period of time, so the initial slope of the signal change curve corresponding to the touch capacitance is constant (can be approximated to 1), and then according to the initial slope, the characteristics of the touch capacitance can be determined as the preset characteristics, that is, the touch capacitance is a biological capacitance, and a touch signal can be generated at this time; if the initial slope of the signal change curve corresponding to the touch capacitance fluctuates and the slope is not 1, it is considered that the touch capacitance is the capacitance brought by other objects, and no touch signal is generated at this time.

[0066] In some optional examples, the controller may be configured to determine whether the characteristic of the touch capacitance is a preset characteristic according to a threshold range of the touch capacitance.

[0067] Specifically, when the trigger device is triggered by different media, the capacitance value changes caused are different. Therefore, based on the threshold range of the detected touch capacitance, when it is determined that the threshold range of the touch capacitance meets the requirements, it is determined that the characteristics of the touch capacitance are preset characteristics, and a touch signal can be generated at this time; otherwise, it is determined that the characteristics of the touch capacitance are not preset characteristics, or the touch capacitance is the capacitance brought by other objects, and no touch signal is generated at this time.

[0068] In some optional examples, the upper and lower limits of capacitance when the trigger device is triggered by different media can be obtained through pre-testing or historical experience, and then the threshold range of touch capacitance when the trigger device is triggered by the corresponding media can be determined.

[0069] In some optional examples, the controller may be configured to determine whether the characteristic of the touch capacitance is a preset characteristic according to a capacitance difference of the touch capacitance within a preset time.

[0070] Specifically, if it is the capacitance caused by human touch, within the preset time, the person always touches the trigger device, so the capacitance value caused is constant or fluctuates slightly, so that the capacitance difference of the touch capacitance within the preset time is small, or even close to 0, so the characteristics of the touch capacitance can be determined as the preset characteristics based on the size of the capacitance difference.

[0071] As can be seen from the above, at least one of the above three methods can be used to determine the characteristics of the touch capacitor, which improves the flexibility of the judgment process, and can be applied to different application scenarios as needed, and accurately identify the touch capacitor human touch signal with preset characteristics.

[0072] It is to be understood that the above-mentioned examples for selecting a touch capacitor with preset characteristics are merely illustrative and should not be construed as limiting the present invention.

[0073] In actual application, for some control devices (such as hidden door handles and charging port covers), it is very easy to freeze in winter or in bad weather conditions (such as freezing rain), or the ambient temperature around the control devices is too low, which will cause the control devices to fail to open normally. When such a situation occurs, it is difficult to open the cover regardless of pressing or pressing the button, which will cause great trouble to the owner when traveling.

[0074] In this case, the trigger device in the embodiment of the present disclosure also has a heating function, so that the control device can be heated by the trigger device to melt the ice on the control device and the surrounding area, so that the control device can be opened normally.

[0075] In other words, the trigger device has both heating and touch sensing functions. In actual application, the inventor further discovered that when the trigger device is heating, the current flowing through the trigger device is relatively large, and it is not suitable to touch the trigger device at this time, that is, the capacitive touch sensing cannot be performed, otherwise a large current will flow into the capacitor sampling pin, thereby burning the controller.

[0076] In order to improve the safety and stability of the control component during operation, the control component may further include a switch device located on the path between the trigger device and the controller.

[0077] Correspondingly, the controller can also be used to output a gating control signal to the switch device according to the acquired electrical parameter changes of the trigger device, so as to control the on-off state of the switch device.

[0078] Furthermore, when the gating control signal is a heating control signal, the switch device is in a gating state, and the controller is used to control the heating process of the trigger.

[0079] Specifically, when the strobe control signal is a heating control signal, it indicates that the trigger device is not touched and the electrical parameters of the trigger device are not changed, so the heating operation can be performed.

[0080] When the selection control signal is a parameter detection signal, the switch device is in an off state, and the controller executes a process of generating the touch signal.

[0081] Specifically, when the strobe control signal is a parameter detection signal, it indicates that the trigger device is touched and the electrical parameters of the trigger device change. At this time, a touch signal needs to be generated to execute the process of controlling the control state of the control device.

[0082] In some embodiments of the present disclosure, the working process of the trigger device can be determined based on the following method: when the controller determines that the electrical parameters of the trigger device have not changed, the controller outputs a heating control signal that puts the switching device in an on state, that is, the trigger device is in a heating process; and when it is determined that the electrical parameters of the trigger device have changed, the controller outputs a parameter detection signal that puts the switching device in a disconnected state, so as to execute the process of controlling the control state of the control device.

[0083] More specifically, when it is determined that the electrical parameters of the trigger device have not changed, the controller outputs an enable control signal that puts the switching device in an enable state to execute the heating process of the trigger device. When it is determined that the electrical parameters of the trigger device have changed, the controller outputs an enable control signal that puts the switching device in an off state to execute the process of acquiring the electrical parameters of the trigger device and generate the touch signal.

[0084] That is to say, when the electrical parameters of the trigger device have not changed, it means that the trigger device has not been triggered. At this time, the switch device can be put into an on state, and the heating operation is performed while the switch device is on; and when the electrical parameters of the trigger device change, it means that the trigger device is triggered. At this time, the switch device is disconnected, and the touch signal generation operation is performed while the switch device is off. Therefore, the use of this patrol scheme can achieve the two effects of heating and capacitance detection, and realize the multiplexing of multiple functions of the trigger device, which can improve the integration of the control components and reduce the overall volume of the control components, so as to further reduce the impact on the appearance of the car.

[0085] It should be noted that, in the case where there is a strong demand for heating (such as when the car is just started), the duty cycle of the selection control signal can be adjusted to increase the heating time, thereby improving the heating efficiency.

[0086] In some embodiments of the present disclosure, as can be seen from the foregoing content, when icing occurs or the ambient temperature around the control device is too low, a heating operation can be performed.

[0087] To this end, this solution also provides an icing detection solution.

[0088] Specifically, as cars develop towards a smarter direction, the scenarios and functions of human-computer interaction are also richer. Therefore, the disclosed embodiment can determine whether the control device is frozen according to the ambient temperature and the corresponding stall current when the control device is operated, and then remind the user to turn on the heating function in advance.

[0089] Specifically, the car or the control device also has a temperature detection device, and the temperature detection device is used to detect the ambient temperature of the car or the control device.

[0090] Correspondingly, the controller is electrically connected to the temperature detection device, and can also be used to determine the freezing condition on the control device based on the ambient temperature and the set temperature value, as well as the starting current and the stall current when the control device is operated.

[0091] Specifically, the temperature detection device can detect the ambient temperature of the vehicle or the control device, and can generate a temperature detection signal corresponding to the ambient temperature to the controller. The controller then determines the freezing condition on the control device based on the ambient temperature and the set temperature value, as well as the starting current and the stall current when the control device is operated.

[0092] In some embodiments, when it is determined that the ambient temperature is lower than a set temperature value (e.g., 0°C) and the starting current is greater than a preset stall current, it is determined that there is ice on and around the control device; otherwise, it can be considered that there is no ice on and around the control device and no heating operation may be performed.

[0093] It should be noted that, first, the stall current in the embodiment of the present disclosure may refer to the current passing through the stator winding of the motor when the rotor of the motor is fixed or "stall", and the stall current can be known in advance; second, for different application scenarios, the set temperature value is different.

[0094] In some embodiments of the present disclosure, the temperature detection device is any one or more of a temperature sensor and a thermistor on a control device.

[0095] More specifically, when a temperature detection device is provided on a car, the temperature detection device is a temperature sensor; when a temperature detection device is provided on a control device, the temperature detection device is a thermistor, so the type of the temperature detection device can be flexibly selected according to the position of the temperature detection device.

[0096] In some optional embodiments of the present disclosure, the functions of the control component may be further expanded so that the control component can better perform the operation of the vehicle.

[0097] For example, there is a situation where a car is parked on the side of the road and the engine is not turned off or in other states, and another user accidentally touches the trigger device. Then, according to the original configuration logic, a series of related operations will be performed, which may be what the user (or car owner) does not want to happen.

[0098] In order to avoid the above situation, the car is also provided with a storage device for storing user fingerprints, and the storage device is electrically connected to the controller.

[0099] The user may refer to the car owner or another person associated with the car owner. The embodiment of the present invention does not limit the user and is specifically set according to the car owner.

[0100] Correspondingly, the controller may also be configured to generate a touch signal when the trigger device is triggered and when it is determined that the detected fingerprint of the current user matches the stored user fingerprint.

[0101] Specifically, a fingerprint recognition sensor can be set in the area where the trigger device is touched, and then the fingerprint recognition sensor can transmit the recognized fingerprint to the controller, so that the controller can perform a matching verification operation. In this way, when it is determined that the detected fingerprint of the current user matches the stored user fingerprint, it means that the current user really wants to perform at least one of the operations on the car, and thus a touch signal can be generated.

[0102] In some embodiments of the present disclosure, the trigger device may include an electric heating element. By making the trigger device an electric heating element, when the electric heating element is touched, it can respond quickly and change its own capacitance value in a very short time to shorten the reaction time of the control component. The electric heating element can be heated quickly and has high heating efficiency.

[0103] In an optional example, the electric heating element can be an element that meets the heating requirements, such as a heating wire, a conductive cloth, etc.

[0104] In some embodiments of the present disclosure, the material of the electric heating element is a conductive material, for example, at least one of copper, nickel-chromium alloy, and tungsten. By using such a material with a lower resistivity as the electric heating element, the heating efficiency can be improved and it is beneficial to detect the effective contact capacitance change value.

[0105] In some other embodiments, the conductive material may also be other metals, such as silver, aluminum, etc., which are not illustrated one by one here.

[0106] In the disclosed embodiment, the resistance of the electric heating element should not be too large or too small. If the resistance of the electric heating element is too large, the electric heating element itself consumes more energy and the heating efficiency is low; if the resistance of the electric heating element is too small, it is easy to cause excessive instantaneous current and there is a possibility of burning the electric heating element. Based on this, the resistance of the electric heating element can be 1Ω to 5Ω.

[0107] In addition, the resistance of the electric heating element is set to 1Ω to 5Ω because the electric heating element needs to have the ability to conduct large currents. Current passenger car batteries are usually powered by 12V. Considering short-term overcurrent conditions, the heating wire needs to have a current conduction capacity of at least 10A.

[0108] In some embodiments, the control device may include one or more of an interface cover, a door handle and a tailgate. By making the control device include one or more of an interface cover, a door handle and a tailgate, different operations can be performed on the car. For example, the door handle is used to open and close the door, the interface cover is used to open or close the charging port (charging port or refueling port), and the tailgate is used to open and close the rear compartment, so as to further improve the convenience of car operation.

[0109] In a specific embodiment, the interface cover may include: a fuel filler cap or a charging port cap.

[0110] In the disclosed embodiment, the trigger device can be arranged along the circumference of the control device, which makes less improvement to the control device, and the trigger device is located closer to the edge of the control device, which has a better heat transfer effect, and when the trigger device is used as a heating device, the selection of the ice melting point is more targeted.

[0111] To facilitate understanding, the following description will be given using specific examples.

[0112] In some embodiments of the present disclosure, see Figure 3 A schematic diagram of the relative relationship between a control device and a trigger device in an embodiment of the present disclosure is shown in FIG. Figure 3 As shown, when the control device 110 is an interface cover, the trigger device 120 can be set at the circumferential edge of the control device 110. In this way, the trigger device 120 is located closer to the edge of the control device 110, the heat transfer effect is better, and when the trigger device 120 is used as a heating device, the selection of the ice melting point is more targeted.

[0113] It should be noted that when using Figure 3In the arrangement shown, a groove can be made on the periphery of the control device 110, and after the trigger device 120 is embedded, it can be sealed and fixed.

[0114] In some embodiments of the present disclosure, in order to further improve the convenience of automobile operation, corresponding unlocking solutions can also be adopted to achieve corresponding operations.

[0115] For example, combined with Figure 1 and Figure 3 , see Figure 4 A schematic diagram of the relative relationship between a control device and a trigger device in an embodiment of the present disclosure is shown in FIG. Figure 4 As shown, the manipulation assembly 100 further includes a first sensor device 150 located on a surface of the manipulation device 110 and electrically connected to the controller 130 .

[0116] The first sensor device 150 is used to detect the movement path of the control device 110 (eg, the interface cover) when it is touched, and to generate a corresponding detection signal to the controller.

[0117] Specifically, the trigger device 120 can be arranged according to the original scheme, except that the arrangement position of the first sensor device 150 (such as a touch sensor) can be arranged according to Figure 3 The first sensor element 150 can be designed in the style shown, and the first sensor element 150 can be designed in a style similar to a "slider" sensor.

[0118] For example, when a finger or the like touches a corresponding area, the amount of signal generated will be significantly different from that in other areas.

[0119] Correspondingly, the controller 130 may also be configured to perform an unlocking operation when it is determined that the moving path corresponding to the detection signal is the same as a preset path.

[0120] Specifically, the detection signal generated by the first sensor device 150 can be transmitted to the controller 130. The controller 130 can determine the signal amount caused by the sliding of an object in combination with the algorithm of the preset slider solution, thereby realizing an unlocking solution of a specific shape.

[0121] It should be noted that Figure 4 The distribution position, shape, etc. of the illustrated first sensor device 150 are all examples, which are used to indicate that the first sensor device 150 can be used to detect the movement path of the control device when it is touched. Different patterns can be set at different positions on the surface of the control device to better reflect individuality, and it should not be understood as a limitation of the present invention.

[0122] In some embodiments of the present disclosure, see Figure 5 Another schematic diagram of the relative relationship between the control device and the trigger device in the embodiment of the present disclosure is shown in FIG.
