[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0021] According to the first aspect of this application, Figure 1 As shown, an inductive antenna assembly is provided, including: a first antenna unit 110 and a second antenna unit 120. The first antenna unit 110 includes a first sensor 111 and a second sensor 112, and the second antenna includes a third sensor 123 and a fourth sensor 124. The distance between the first sensor 111 and the target plane is greater than the distance between the second sensor 112 and the target plane, and the distance between the third sensor 123 and the target plane is greater than the distance between the fourth sensor 124 and the target plane. The first sensor 111 and the fourth sensor 124 are adapted to be connected to the first pin 201 of the controller 200, and the second sensor 112 and the third sensor 123 are adapted to be connected to the second pin 202 of the controller. The target plane is the plane on which the target object carrying the induction antenna is placed.
[0022] By setting up the first antenna unit 110 and the second antenna unit 120, the sensing range is increased without causing an increase in parasitic capacitance. Each antenna unit is equipped with two sensors to detect kicking motions, which reduces false triggering and insensitive triggering, and increases the success rate. The first sensor 111 and the fourth sensor 124 share the first pin 201, and the second sensor 112 and the third sensor 123 share the second pin 202, which reduces design complexity.
[0023] By employing the above-described method, the staggered arrangement of sensors can significantly improve the detection accuracy of the antenna and reduce detection errors caused by vehicle body accessories and external interference. Furthermore, the fact that the first antenna unit 110 and the second antenna unit 120 share the same controller 200 can reduce hardware costs and layout complexity.
[0024] In some embodiments, the polarities of the first pin 201 and the second pin 202 are opposite.
[0025] In some embodiments, the target plane is the ground.
[0026] In some embodiments, the first sensor 111, the second sensor 112, the third sensor 123, and the fourth sensor 124 are elongated or U-shaped. Preferably, the first sensor 111, the second sensor 112, the third sensor 123, and the fourth sensor 124 are arranged laterally. This arrangement effectively increases the sensing range of the sensors.
[0027] In some embodiments, the first sensor 111, the second sensor 112, the third sensor 123, and the fourth sensor 124 are fixed to the vehicle body by an adhesive process.
[0028] According to the second aspect of this application, such as Figure 1 As shown, a foot-operated control device is provided, including a controller 200 and an inductive antenna assembly according to the first aspect of this application. A first antenna unit 110 is disposed in a first region of the vehicle body, and a second antenna unit 120 is disposed in a second region of the vehicle body. The controller 200 is configured to control the vehicle door to perform an action in response to the inductive antenna assembly detecting a foot-operated action. Distributing antenna units in two regions of the vehicle body increases the sensing range. For example, by distributing the first antenna unit 110 and the second antenna unit 120 on the left and right sides of the tailgate respectively, the tailgate can be opened or closed using either foot by performing a foot-operated action, without needing to perform the action in a specific location.
[0029] In some embodiments, the controller 200 is configured to: determine a target antenna unit based on the signal change amplitude and / or signal change frequency of the first pin 201 and the second pin 202, wherein the target antenna unit is the first antenna unit 110 or the second antenna unit 120; and call the signal of the target antenna unit to perform a kick judgment to determine whether a kicking action is detected.
[0030] In some embodiments, the controller is configured to: determine the target antenna element as the first antenna element 110 when the signal change amplitude of the first pin 201 is greater than the signal change amplitude of the second pin 202; and determine the target antenna element as the second antenna element 120 when the signal change amplitude of the second pin 202 is greater than the signal change amplitude of the first pin 201.
[0031] In some embodiments, the controller is configured to: determine the target antenna element as the first antenna element 110 when the signal change frequency of the first pin 201 is greater than the signal change frequency of the second pin 202; and determine the target antenna element as the second antenna element 120 when the signal change frequency of the second pin 202 is greater than the signal change frequency of the first pin 201.
[0032] In some embodiments, the controller is configured to: determine the target antenna element as the second antenna element 120 when the signal change amplitude of the first pin 201 is greater than the signal change amplitude of the second pin 202; and determine the target antenna element as the first antenna element 110 when the signal change amplitude of the second pin 202 is greater than the signal change amplitude of the first pin 201.
[0033] In some embodiments, the controller is configured to: determine the target antenna element as the second antenna element 120 when the signal change frequency of the first pin 201 is greater than the signal change frequency of the second pin 202; and determine the target antenna element as the first antenna element 110 when the signal change frequency of the second pin 202 is greater than the signal change frequency of the first pin 201.
[0034] In some embodiments, the first sensor 111 and the fourth sensor 124 are connected to the first pin 201 of the controller 200, and the second sensor 112 and the third sensor 123 are connected to the second pin 202 of the controller 200, as shown below. Figure 3 As shown, when the signal change amplitude of the first pin 201 of the controller 200 is greater than the signal change amplitude of the second pin 202, the signal of the first antenna unit 110 is invoked for kick detection; as Figure 4 As shown, when the signal change amplitude of the second pin 202 of the controller 200 is greater than the signal change amplitude of the first pin 201, the signal of the second antenna unit 120 is invoked for kick detection. When the signal change amplitude of the first pin 201 of the controller 200 is greater than the signal change amplitude of the second pin 202, it indicates that the sensor connected to the first pin 201 is closer to the object triggering the signal than the sensor connected to the second pin 202. Since the first sensor 111 is closer to the user than the second sensor 112, and the third sensor 123 is closer to the user than the fourth sensor 124, the signal is detected by the first antenna unit. When the signal change amplitude of the first pin 201 of the controller 200 is less than the signal change amplitude of the second pin 202, it indicates that the sensor connected to the first pin 201 is farther from the object triggering the signal than the sensor connected to the second pin 202. Since the first sensor 111 is closer to the user than the second sensor 112, and the third sensor 123 is closer to the user than the fourth sensor 124, the signal is detected by the second antenna unit.
[0035] In some embodiments, the controller 200 is configured to: when the target antenna element is the first antenna element 110, if the difference between the signal waveform of the first antenna element 110 and a preset waveform is less than or equal to a preset threshold, determine that a kicking action has occurred in the first region of the vehicle body; if the difference between the signal waveform of the first antenna element 110 and the preset waveform is greater than the preset threshold, determine that no kicking action has occurred. The signal collected by the first antenna element 110 is not necessarily triggered by a kicking action, so kicking judgment is required. The signal generated by the kicking action can be sampled and calibrated before the vehicle leaves the factory, and a reasonable difference threshold, i.e., the preset threshold, can be set.
[0036] In some embodiments, the controller 200 is configured to: when the target antenna unit is the second antenna unit 120, if the difference between the signal waveform of the second antenna unit 120 and a preset waveform is less than or equal to a preset threshold, determine that a kicking action has occurred in the second region of the vehicle body; if the difference between the signal waveform of the first antenna unit 110 and a preset waveform is greater than the preset threshold, determine that no kicking action has occurred. The signal collected by the second antenna unit 120 is not necessarily triggered by a kicking action, therefore kicking judgment is required. The signal generated by the kicking action can be sampled and calibrated before the vehicle leaves the factory, and a reasonable difference threshold, i.e., a preset threshold, can be set.
[0037] In some embodiments, the controller 200 is configured to: detect a kicking action when the door is open and control the door to close; detect a kicking action when the door is closed and control the door to open. A user kicking action typically indicates an intention to change the state of the door; therefore, the door is opened when it is closed and closed when it is open.
[0038] The following will combine Figure 2 The following examples illustrate the foot-kicking control process of this application: S101, Start; Enter S102; S102, Controller 200 pin receives antenna signal; proceed to S103; S103.

S104: Compare the signal of the first antenna unit 110 with the threshold of the first antenna unit 110 to determine the kick; proceed to S106; S105: Call the signal of the second antenna unit 120 and compare the threshold of the second antenna unit 120 to perform a kick judgment; proceed to S106; S106. Determine whether a kicking action occurred; if yes, proceed to S107; if no, proceed to S108.
