Background Art

[0002] With the development of intelligent vehicle body technology, many cars are equipped with PEPS (also known as comfort entry, or keyless entry) systems. When the driver carrying the original car remote control steps into the specified range, the door will automatically unlock when the driver pulls the door handle, and the door will automatically lock when the driver presses the door handle at the specified position. Generally, the original car is only equipped with one or two original car remote controls, which are almost impossible to copy, thus effectively preventing the car from being stolen. However, when multiple people share the same car, they need to reserve and obtain the original car remote control in advance, which is not convenient in actual application. Summary of the invention

[0003] In view of the above problems, the present invention is proposed to provide a device and method for opening and closing a lock outside a vehicle using an original vehicle remote controller inside the vehicle, which overcomes the above problems or at least partially solves the above problems.

[0004] In a first aspect, the present invention provides a device for opening and closing a lock outside a vehicle by using an original vehicle remote controller inside the vehicle.

[0005] The device for opening and closing the lock outside the vehicle by using the original vehicle remote controller inside the vehicle comprises:

[0006] The original vehicle remote controller is arranged in the vehicle, and can communicate with the device in the vehicle by receiving the first radio signal so that the vehicle can confirm whether the original vehicle remote controller is in the vehicle, and can communicate with the device in the vehicle by sending the second radio signal so as to transmit the control command of opening and closing the door lock to the vehicle;

[0007] A control box is arranged in the vehicle, and can prevent or interfere with the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, so that the vehicle cannot find the location of the original vehicle remote control;

[0008] The smart remote controller is capable of communicating with the control box by receiving a third radio signal so that the control box can confirm whether the smart remote controller is in the vehicle, and is capable of communicating with the control box by sending a fourth radio signal so as to transmit a control command for opening and closing the vehicle door locks to the control box;

[0009] After confirming that the smart remote control is outside the vehicle and receiving the control command of opening and closing the door locks transmitted by the smart remote control, the control box prevents or interferes with the original vehicle remote control from communicating with the equipment in the vehicle by receiving the first radio signal, and controls the original vehicle remote control to transmit the control command of opening and closing the door locks to the vehicle.

[0010] In one embodiment, the control box includes a signal receiving module, a signal sending module, a central processing unit, and a controller; the central processing unit is communicatively connected to the signal receiving module, the signal sending module, and the controller respectively; the signal receiving module is capable of receiving a fourth radio signal; the signal sending module is capable of sending a third radio signal; the controller is capable of sending a control instruction to the original vehicle remote control, and the original vehicle remote control transmits a control command for opening and closing the door locks to the vehicle according to the control instruction.

[0011] In one embodiment, the original vehicle remote control includes a first radio signal receiving antenna, and the control box also includes an analog circuit, which is communicatively connected to the controller and is used to short-circuit the first radio signal receiving antenna.

[0012] In one embodiment, the control box further includes an interference module, which is communicatively connected to the controller and is used to generate a radio signal with the same frequency as the first radio signal.

[0013] In one implementation, the interference module includes a single-chip microcomputer, an amplifier circuit, and a transmitting antenna, and the single-chip microcomputer, the amplifier circuit, and the transmitting antenna are electrically connected in sequence.

[0014] In one embodiment, the control box further includes an execution circuit, which is communicatively connected to the controller and is used to cut off the power supply of the original vehicle remote controller.

[0015] In one embodiment, the control box further includes an execution circuit, which is communicatively connected to the controller and is used to disconnect the first radio signal transmitting antenna of the vehicle.

[0016] The second method of the present invention provides a method for opening and closing a lock outside a vehicle by using an original vehicle remote controller inside the vehicle.

[0017] The method of using the original vehicle remote controller in the vehicle to open and close the vehicle lock comprises the following steps:

[0018] The smart remote controller outside the vehicle communicates with the control box by receiving a third radio signal so that the control box can confirm the location of the smart remote controller;

[0019] The intelligent remote controller communicates with the control box by sending a fourth radio signal to transmit a control command for opening or closing the vehicle door lock to the control box;

[0020] The control box arranged in the vehicle blocks or interferes with the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, so that the vehicle cannot find the location of the original vehicle remote control arranged in the vehicle, and controls the original vehicle remote control to communicate with the device in the vehicle by sending the second radio signal to transmit the control command of opening and closing the door lock to the vehicle.

[0021] In the embodiment of the present invention, the control box is used to prevent or interfere with the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, so that the vehicle cannot find the location of the original vehicle remote control. Therefore, even if the original vehicle remote control is arranged in the vehicle, it does not affect the operation of locking the vehicle outside the vehicle. After confirming that the smart remote control is outside the vehicle and receiving the control command of opening and closing the door lock transmitted by the smart remote control, the control box prevents or interferes with the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, and controls the original vehicle remote control to transmit the control command of opening and closing the door lock to the vehicle.

[0022] In the case where multiple drivers share the same vehicle, each driver can be equipped with an intelligent remote controller, and the driver can use his or her own intelligent remote controller to open and close the car door. This solves the problem that when multiple people share the same vehicle, they need to reserve and obtain the original vehicle remote controller in advance, which is inconvenient in actual use.

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but cannot be understood as limiting the present invention. A person of ordinary skill in the art may make various changes, modifications, substitutions and variations to these embodiments without departing from the principles and purpose of the present invention. The scope of the present invention is defined by the claims and their equivalents.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In addition, the terms "include", "comprises" and any variations thereof are intended to cover non-exclusive inclusions.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] At present, many cars are equipped with PEPS (also known as comfort entry, or keyless entry) systems. When the driver carrying the original car remote control steps into the specified range, the car door automatically unlocks when the driver pulls the door handle, and automatically locks when the driver presses the door handle at the specified position. Since the number of original car remote controls is limited, when multiple people share the same vehicle, they need to reserve and obtain the original car remote control in advance, which is not convenient in actual use.

[0029] To overcome the above problems or at least partially solve the above problems, the embodiments of the present application provide a device for opening and closing the door outside the vehicle using the original vehicle remote control inside the vehicle, through which the driver can open and close the door without carrying the original vehicle remote control. The embodiments are described in detail below.

[0030] Figure 1 The working principle diagram of a device for opening and closing the car lock outside the car using the original car remote control in the car provided by the embodiment of the present invention. The device for opening and closing the car lock outside the car using the original car remote control in the car includes the original car remote control, a control box, and an intelligent remote control.

[0031] The original vehicle remote control, that is, the original vehicle smart key, is arranged in the vehicle. It can communicate with the device in the vehicle by receiving a first radio signal to enable the vehicle to confirm whether the original vehicle remote control is in the vehicle, and can communicate with the device in the vehicle by sending a second radio signal to transmit the control command of opening and closing the door lock to the vehicle.

[0032] The driver carrying the original car remote control steps into the designated range, such as within 1 meter of the vehicle, and pulls the door handle. After the vehicle receives the unlocking signal, it sends the unlocking signal to the vehicle's low-frequency antenna. After the vehicle's low-frequency antenna receives the unlocking signal, it sends a first radio signal - a low-frequency trigger signal to the original car remote control. After the original car remote control receives the low-frequency trigger signal, it sends a second radio signal - a high-frequency unlocking signal. After the vehicle's high-frequency receiver receives the high-frequency unlocking signal, the door is unlocked. It should be understood that the first radio signal and the second radio signal can also be other radio signals, which are not listed here one by one.

[0033] Generally, when the original car remote controller is arranged in the vehicle, the device in the vehicle can confirm the position of the original car remote controller by communicating with the original car remote controller, so that the vehicle locking operation cannot be performed outside the vehicle. In this embodiment, the control box is used to prevent or interfere with the original car remote controller from communicating with the device in the vehicle by receiving the first radio signal, so that the vehicle cannot find the position of the original car remote controller. Therefore, even if the original car remote controller is arranged in the vehicle, it does not affect the vehicle locking operation outside the vehicle.

[0034] The smart remote controller can communicate with the control box by receiving the third radio signal so that the control box can confirm whether the smart remote controller is in the vehicle, and can communicate with the control box by sending the fourth radio signal so as to transmit the control command of opening and closing the door lock to the control box. After confirming that the smart remote controller is outside the vehicle and receiving the control command of opening and closing the door lock transmitted by the smart remote controller, the control box prevents or interferes with the original vehicle remote controller from communicating with the device in the vehicle by receiving the first radio signal, and controls the original vehicle remote controller to transmit the control command of opening and closing the door lock to the vehicle.

[0035] For example, when a driver carrying a smart remote control steps into a designated range, such as within 1 meter of a vehicle, the control box sends a third radio signal, such as an RFID 125KHZ low-frequency signal, to the smart remote control. After receiving the third radio signal, the smart remote control sends a fourth radio signal, such as an FSK 394MHZ high-frequency signal. After receiving the fourth radio signal, the control box blocks or interferes with the original vehicle remote control from communicating with the equipment in the vehicle by receiving the first radio signal, so that the vehicle cannot find the location of the original vehicle remote control, and controls the original vehicle remote control to transmit control commands for opening and closing the door locks to the vehicle, such as controlling the original vehicle remote control to send a second radio signal - a high-frequency unlocking signal to the vehicle's high-frequency receiver. After the vehicle's high-frequency receiver receives the high-frequency unlocking signal, the door is unlocked.

[0036] Specifically, the control box may include a signal receiving module, a signal sending module, a central processing unit, and a controller. The central processing unit is communicatively connected with the signal receiving module, the signal sending module, and the controller respectively. The signal receiving module is capable of receiving a fourth radio signal, and the signal sending module is capable of sending a third radio signal. The controller is capable of sending a control instruction to the original vehicle remote controller, and the original vehicle remote controller transmits a control command of opening and closing the door lock to the vehicle according to the control instruction.

[0037] In one embodiment, the original vehicle remote controller includes a first radio signal receiving antenna. The control box may also include an analog circuit, which is communicatively connected to the controller and is used to short-circuit the first radio signal receiving antenna, so that the original vehicle remote controller cannot send the first radio signal, thereby preventing the original vehicle remote controller from communicating with the device in the vehicle by receiving the first radio signal, so that the vehicle cannot find the location of the original vehicle remote controller.

[0038] In another embodiment, the control box may further include an interference module, which is communicatively connected to the controller and is used to generate a radio signal with the same frequency as the first radio signal, so as to interfere with the original vehicle remote control communicating with a device in the vehicle by receiving the first radio signal, thereby making it impossible for the vehicle to find the location of the original vehicle remote control.

[0039] The interference module may include a single-chip microcomputer, an amplifier circuit, and a transmitting antenna, and the single-chip microcomputer, the amplifier circuit, and the transmitting antenna are electrically connected in sequence.

[0040] In another embodiment, the control box may further include an execution circuit, which is communicatively connected to the controller and is used to cut off the power supply of the original vehicle remote control, so as to prevent the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, so that the vehicle cannot find the location of the original vehicle remote control. For example, when the control box confirms that the smart remote control is outside the vehicle and receives the control command of opening and closing the door lock transmitted by the smart remote control, the power supply of the original vehicle remote control is cut off for 3 seconds, so that the vehicle cannot find the location of the original vehicle remote control.

[0041] In another embodiment, the control box may further include an execution circuit, which is communicatively connected to the controller and is used to disconnect the first radio signal sending antenna of the vehicle to prevent the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, thereby preventing the vehicle from finding the location of the original vehicle remote control.

[0042] In this embodiment, the control box is used to prevent or interfere with the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, so that the vehicle cannot find the location of the original vehicle remote control. Therefore, even if the original vehicle remote control is arranged in the vehicle, it does not affect the operation of locking the vehicle outside the vehicle. After confirming that the smart remote control is outside the vehicle and receiving the control command of opening and closing the door lock transmitted by the smart remote control, the control box prevents or interferes with the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, and controls the original vehicle remote control to transmit the control command of opening and closing the door lock to the vehicle.

[0043] In the case where multiple drivers share the same vehicle, each driver can be equipped with an intelligent remote controller, and the driver can use his or her own intelligent remote controller to open and close the car door. This solves the problem that when multiple people share the same vehicle, they need to reserve and obtain the original vehicle remote controller in advance, which is inconvenient in actual use.

[0044] The embodiment of the present invention also provides a method for opening and closing a lock outside a vehicle by using an original vehicle remote control in the vehicle, and the method is implemented by using the device for opening and closing a lock outside a vehicle by using an original vehicle remote control in the vehicle in the above embodiment. The method specifically includes the following steps:

[0045] 1) The smart remote controller outside the vehicle communicates with the control box by receiving a third radio signal so that the control box confirms the location of the smart remote controller.

[0046] 2) The intelligent remote controller communicates with the control box by sending a fourth radio signal to transmit a control command of opening or closing the vehicle door lock to the control box.

[0047] 3) The control box arranged in the vehicle blocks or interferes with the original vehicle remote control from communicating with the device in the vehicle by receiving the first radio signal, so that the vehicle cannot find the location of the original vehicle remote control arranged in the vehicle, and controls the original vehicle remote control to communicate with the device in the vehicle by sending the second radio signal to transmit the control command of opening and closing the door lock to the vehicle.
