The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A tailgate control system 100 of a vehicle according to an embodiment of the utility model is described below with reference to fig. 1 and 2.
As shown in fig. 1 and 2, a tailgate control system 100 of a vehicle according to an embodiment of the present invention includes: the vehicle rear bumper comprises a first sensing device 10, a second sensing device 20, a third sensing device 30 and a control device 40, wherein the first sensing device 10, the second sensing device 20 and the third sensing device 30 are all arranged on a rear bumper 60 of a vehicle, the first sensing device 10 and the second sensing device 20 can respectively sense the kicking action of a user to output a first sensing signal and a second sensing signal, the third sensing device 30 can output a detection signal when detecting that a person is within a preset distance range of the vehicle, the control device 40 is in communication connection with the first sensing device 10, the second sensing device 20 and the third sensing device 30, and the control device 40 can recognize the first sensing signal and/or the second sensing signal as an invalid signal when receiving the detection signal output by the third sensing device 30 so as to enable a rear back door of the vehicle not to act.
Wherein, the first induction device 10, the second induction device 20, the third induction device 30 and the control device 40 can be connected through a plug connector 50, the first induction device 10, the second induction device 20 and the third induction device 30 are in a parallel state, the first induction device 10, the second induction device 20 and the third induction device 30 do not interfere with each other, a first threshold value and a second threshold value which are preset are stored in the control device 40, when any one of the first induction signal and the second induction signal output by the first induction device 10 and the second induction device 20 satisfies the first threshold value, the door opening and closing condition of the back door of the vehicle is satisfied, at this time, the control device 40 judges the detection signal output by the third induction device 30, when the value of the detection signal satisfies the second threshold value, the control device 40 identifies the first induction signal and/or the second induction signal as an invalid signal to make the back door of the vehicle not act, the back door control system 100 of the vehicle can avoid the misjudgment phenomenon, and when the value of the detection signal output by the third sensing device 30 does not satisfy the second threshold, the control device 40 recognizes the first sensing signal and/or the second sensing signal as the valid signal to open or close the back door of the vehicle.
Specifically, when the user places articles in the tailgate, the feet and the legs move, the first sensing device 10 and the second sensing device 20 sense the movement of the feet and the legs and output a first sensing signal and a second sensing signal, but because the distance between the human body position and the third sensing device 30 is short, the third sensing device 30 can output a detection signal, the control device 40 recognizes the first sensing signal and/or the second sensing signal as an invalid signal when receiving the detection signal output by the third sensing device 30 so as to make the tailgate of the vehicle not move, thereby preventing the tailgate from being automatically closed, and avoiding the tailgate from hurting the user. When the knees or legs of a user touch the rear bumper 60 carelessly, the rear bumper 60 vibrates, the first sensing device 10, the second sensing device 20 and the rear bumper 60 mounted on the rear bumper 60 can move relatively, so that the first sensing device 10 and the second sensing device 20 output a first sensing signal and a second sensing signal, but the third sensing device 30 outputs a detection signal because the distance between the human body position and the third sensing device 30 is relatively short, and the control device 40 recognizes the first sensing signal and/or the second sensing signal as an invalid signal when receiving the detection signal output by the third sensing device 30, so that the tailgate of the vehicle does not move, thereby preventing the tailgate from closing automatically and preventing the tailgate from injuring the user. When the back door is in a closed state, when a person walks along the rear bumper 60, the legs and the legs move, the first sensing device 10 and the second sensing device 20 sense the movement of the legs and output a first sensing signal and a second sensing signal, but the third sensing device 30 can preferentially sense the approach of the person and output a detection signal, and the control device 40 recognizes the first sensing signal and/or the second sensing signal as an invalid signal when receiving the detection signal output by the third sensing device 30 so as to make the back door of the vehicle not move, thereby preventing the back door from being automatically opened and avoiding the back door from injuring the user.
Therefore, the first sensing device 10, the second sensing device 20, the third sensing device 30 and the control device 40 are matched, so that the situation that the back door of the vehicle is injured by clamping or bumping a user can be avoided, and the user is prevented from being frightened.
Further, when the time that the detection signal output by the third sensing device 30 satisfies the second threshold is longer than the first preset time, the control device 40 does not determine whether the first sensing signal and the second sensing signal satisfy the first threshold, and when the time that the detection signal output by the third sensing device 30 satisfies the second threshold is longer than the second preset time, the control device 40 determines whether the first sensing signal and the second sensing signal satisfy the first threshold again, so that the determination accuracy of the back door control system 100 can be improved. Preferably, the first preset time may be set to 500 msec, and the second preset time may be set to 50 msec. This arrangement prevents erroneous judgment of the tailgate control system 100 of the vehicle when a person is approaching the trunk or is walking along the rear bumper 60.
In some embodiments of the present invention, the third sensing device 30 is disposed behind the first and second sensing devices 10 and 20 in the front-rear direction of the vehicle. It should be noted that the third sensing device 30 may be disposed at the rearmost side of the rear bumper 60, and since the third sensing device 30 needs to detect whether a person is present within a predetermined distance range of the vehicle, the third sensing device is disposed at a position behind the first sensing device 10 and the second sensing device 20 so as to be closer to the person. The arrangement can enable the third sensing device 30 to output a stronger detection signal when detecting that a person is in the preset distance range of the vehicle, and the third sensing device 30 can detect in a larger range, so that the situation that the back door control system 100 misjudges can be avoided.
In some embodiments of the present invention, as shown in fig. 1 and 2, the third sensing device 30 is disposed at a height higher than the first sensing device 10 and the second sensing device 20 in the height direction of the vehicle. It should be explained that the third sensing device 30 may be disposed at the highest point of the rear bumper 60, and since the third sensing device 30 needs to detect whether a human being exists within a preset distance range of the vehicle, it may be positioned higher than the first and second sensing devices 10 and 20 to be closer to the human body. The arrangement can enable the third sensing device 30 to output a stronger detection signal when detecting that a person is in the preset distance range of the vehicle, and the third sensing device 30 can detect in a larger range, so that the situation that the back door control system 100 misjudges can be avoided.
In some embodiments of the present invention, the first sensing device 10 and the second sensing device 20 are both provided on the lower surface of the rear bumper 60. It should be noted that, the positions of the first sensing device 10 and the second sensing device 20 need to be close to the feet of a user, when the user needs to open or close the back door, the user performs a kicking action, and the first sensing device 10 and the second sensing device 20 can sense the kicking action of the user and output a first sensing signal and a second sensing signal respectively. Set up like this and to make first induction system 10 and second induction system 20 respond to first induction signal of output and second induction signal's intensity stronger when user's the skirting action, first induction system 10 and second induction system 20 can detect at bigger within range, and the user need not to press close to first induction system 10 and second induction system 20 and do the skirting action to can improve user's use and experience.
In some embodiments of the present invention, the first sensing device 10 may be disposed in front of the second sensing device 20 in the front-rear direction of the vehicle. It should be explained that the first sensing device 10 can be used for sensing the instep, and the second sensing device 20 can be used for sensing the ankle, and since the instep is located in front of the ankle in the front-rear direction of the human body, the front-rear direction of the human body is the same as the front-rear direction of the vehicle when the user performs a kicking motion, the first sensing device 10 is disposed in front of the second sensing device 20. So set up and to output first induction signal and second induction signal's intensity when can making first induction system 10 and second induction system 20 response user's the skirting action stronger, first induction system 10 and second induction system 20 can detect at bigger within range, and the user need not to be close to first induction system 10 and second induction system 20 deliberately and do the skirting action to can improve user's use and experience.
In some embodiments of the present invention, as shown in fig. 1 and 2, the second sensing device 20 is disposed at a height higher than that of the first sensing device 10 in the height direction of the vehicle. It should be noted that the first sensing device 10 can be used for sensing the instep, and the second sensing device 20 can be used for sensing the ankle, and since the position of the ankle is higher than the instep in the height direction of the human body, when the user performs the kicking action, the height direction of the human body is the same as the height direction of the vehicle, so the height of the second sensing device 20 is set to be higher than the set height of the first sensing device 10. So set up and to output first induction signal and second induction signal's intensity when can making first induction system 10 and second induction system 20 response user's the skirting action stronger, first induction system 10 and second induction system 20 can detect at bigger within range, and the user need not to press close to first induction system 10 and second induction system 20 and do the skirting action to can improve user's use and experience.
In some embodiments of the present invention, the first sensing device 10, the second sensing device 20, and the third sensing device 30 each extend in a length direction of the rear bumper 60, the length direction of the rear bumper 60 is a width direction of the vehicle, and the first sensing device 10, the second sensing device 20, and the third sensing device 30 are parallel to each other. Further, the lengths of the first sensing device 10, the second sensing device 20 and the third sensing device 30 may be set to be the same length, and the distance between the first sensing device 10 and the second sensing device 20 is smaller than the distance between the second sensing device 20 and the third sensing device 30, that is, the third sensing device 30 is disposed as far away from the first sensing device 10 and the second sensing device 20 as possible, and the first sensing device 10 and the second sensing device 20 are disposed proximate to and close to the lowest portion of the rear bumper 60. It is understood that the present invention is not limited thereto, and the lengths of the first sensing device 10, the second sensing device 20 and the third sensing device 30 may be set to different lengths as long as the first sensing device 10, the second sensing device 20 and the third sensing device 30 can accurately sense the human body. By the arrangement, the third induction device 30 can be prevented from being influenced by a kicking action, the first induction device 10 and the second induction device 20 can be prevented from being influenced by a human body, the first induction device 10, the second induction device 20 and the third induction device 30 can be prevented from being interfered, and therefore the control accuracy of the back door control system 100 can be improved.
In some embodiments of the present invention, the first sensing device 10 and the second sensing device 20 may be both provided as sensing antennas. It should be noted that, the first sensing device 10 and the second sensing device 20 are made of the same material, the first threshold may be set as a capacitance value, the first sensing device 10 and the second sensing device 20 are set as sensing antennas for sensing the kicking motion of the user, when the user performs the kicking motion, the instep and the ankle of the user are close to the sensing antennas, therefore, the capacitances of the first sensing device 10 and the second sensing device 20 are changed, when the control device 40 senses that the capacitance of the sensing antennas reaches the first threshold, the first sensing signal and/or the second sensing signal satisfy the first threshold, and the control device 40 controls the back door of the vehicle to be opened or closed. The induction intensity of the first induction device 10 and the second induction device 20 can be improved, the kicking action of a user can be better induced, and the use experience of the user is improved.
In some embodiments of the present invention, the third sensing device 30 may be configured as a camera or a radar or an inductive antenna. It should be explained that, when the third sensing device 30 is configured as a camera or a radar, the second threshold is a distance length, and when the distance between the third sensing device 30 and the person is lower than the second threshold, that is, the detection signal satisfies the second threshold, the control device 40 recognizes the first sensing signal and/or the second sensing signal as an invalid signal to disable the tailgate of the vehicle. When the third sensing device 30 is set as the sensing antenna, the second threshold is a capacitance value, when the human body approaches the sensing antenna, the capacitance of the sensing antenna changes, and when the capacitance value of the sensing antenna exceeds the second threshold, that is, the detection signal satisfies the second threshold, at this time, the control device 40 recognizes the first sensing signal and/or the second sensing signal as an invalid signal so as to disable the tailgate of the vehicle.
Further, when the third sensing device 30 is configured as an inductive antenna, the tailgate control system 100 can counteract the electromagnetic interference caused by the signal tower, when the vehicle stops under the signal tower, the signal tower emits periodic sinusoidal electromagnetic waves, and the sinusoidal electromagnetic waves can trigger the first sensing device 10, the second sensing device 20, and the third sensing device 30 at the same time, that is, the time difference for triggering the first sensing device 10 and the second sensing device 20 is 0, and when the human body performs a kicking motion to trigger the first sensing device 10 and the second sensing device 20, because the setting height of the second sensing device 20 is higher than the setting height of the first sensing device 10 in the height direction of the vehicle, the kicking motion triggers the first sensing device 10 first and then the second sensing device 20, and the time difference for triggering the first sensing device 10 and the second sensing device 20 is larger, based on this principle, when the difference between the triggering time difference for triggering the first sensing device 10 and the second sensing device 20 and the exiting time difference for exiting the first sensing device 10 and the second sensing device 20 is within 50 ms, the control device 40 determines that the first sensing device 10 and the second sensing device 20 are interfered by the electromagnetic wave, and the first sensing signal, the second sensing signal and the detection signal have the same value, the control device 40 subtracts the detection signal from the first sensing signal or the second sensing signal, when the first sensing device 10 and the second sensing device 20 are only interfered by the electromagnetic wave, the value obtained by subtracting the detection signal from the first sensing signal or the second sensing signal is 0, and when the first sensing device 10 and the second sensing device 20 sense the kicking action, the first sensing device 10 and the second sensing device 20 are not only interfered by the electromagnetic wave but also affected by the kicking action, the third sensing device 30 is not affected by kicking, and the value obtained by subtracting the detection signal from the first sensing signal or the second sensing signal is a signal value affected only by kicking of the user, and when the signal value satisfies the first threshold, the control device 40 controls the back door of the vehicle to open or close. The arrangement can counteract the interference of electromagnetic waves, so that the back door control system 100 of the vehicle is not influenced by the environment, and the use experience of a user can be improved.
In some embodiments of the present invention, the third sensing device 30 may be provided in plurality, and a plurality of the third sensing devices 30 are respectively provided to the back door and the rear bumper 60. It should be noted that the plurality of third sensing devices 30 are disposed on the back door and the rear bumper 60 relatively far away from the first sensing device 10 and the second sensing device 20. The intensity of the output detection signal is stronger when a person is detected within the preset distance range of the vehicle by the plurality of third sensing devices 30, and the plurality of third sensing devices 30 can be detected within a larger range, so that the situation that the back door control system 100 misjudges can be avoided, and the back door can be prevented from being pinched or bruised.
