Description

Technical Field

[0001] The present invention relates to a vehicle key control device, and more specifically, to a control device and method for realizing the function of a vehicle remote control by a mobile terminal.

Background Art

[0002] Conventional automobiles are equipped with an original key remote control for performing specific operations on the vehicle at the time of shipment. As shown in FIG. 4, which is a schematic diagram of a conventional key remote control, the key remote control is provided with a plurality of buttons 91 to 93 for operations such as locking, unlocking, and opening the trunk of the vehicle.

[0003] Conventional key remote controls are often carried by the vehicle owner at all times. However, if they are lost, forgotten, or accidentally left in the vehicle and locked, it will cause great inconvenience and discomfort to the vehicle owner.

Summary of the Invention

[0004] In view of the above problems, the present invention has devised a Bluetooth relay remote control technology for a vehicle remote control. According to this configuration and method, the user can avoid various inconveniences caused by directly using the vehicle key remote control by operating the vehicle key remote control via a Bluetooth device with their own mobile terminal.

[0005] To achieve the above object, a Bluetooth relay remote control device for a vehicle remote control according to the present invention includes a first circuit board, a processor provided on the first circuit board, and a signal transmission circuit provided on the first circuit board and electrically connected to an output end of the processor, and a remote control module which is a circuit module of a vehicle key remote control. A Bluetooth relay controller electrically connected to the remote control module includes a second circuit board, a Bluetooth processor provided on the second circuit board, a Bluetooth transceiver module electrically connected to the input terminal of the Bluetooth processor for receiving Bluetooth signals transmitted from a mobile terminal, and a signal output circuit electrically connected between the output terminal of the Bluetooth processor and the input terminal of the processor of the remote control module, The Bluetooth processor, upon receiving the Bluetooth signal from the Bluetooth transceiver module, controls the signal output circuit to generate a control signal based on the Bluetooth signal and transmit it to the processor of the remote control module, and drives the signal transmission circuit so that the processor transmits a wireless signal to control and operate the automobile based on the control signal.

[0006] To achieve the above objective, the Bluetooth relay remote control method for a vehicle remote control according to the present invention includes the following:

[0007] The remote control module, which is the circuit module for the vehicle key remote control, is physically and electrically connected to the Bluetooth relay controller.

[0008] The Bluetooth relay controller receives the Bluetooth signal transmitted from the mobile device.

[0009] The Bluetooth relay controller generates a control signal based on the Bluetooth signal and outputs it to the remote control module.

[0010] The remote control module controls the vehicle based on the control signals and performs the corresponding operations.

[0011] When a user attempts to control a vehicle to perform operations such as locking or unlocking, they send a Bluetooth signal from their mobile device to a Bluetooth relay controller. The Bluetooth relay controller then directly controls the remote control module (vehicle remote control) and generates a wireless signal to perform the predetermined operation. This method allows the user to operate the manufacturer's original vehicle remote control without modifying or damaging the vehicle. [Brief explanation of the drawing]

[Figure 2] This is a circuit block diagram of a Bluetooth relay remote control device for a vehicle remote control according to the present invention. [Figure 3] This is a circuit block diagram of another embodiment of the Bluetooth relay remote control device for vehicle remotes according to the present invention. [Figure 4] This is a schematic plan view of a conventional vehicle key remote control. [Modes for carrying out the invention]

[0013] As shown in Figure 1, the present invention is a flowchart of a Bluetooth relay remote control method for a vehicle remote control, which includes the following steps.

[0014] S01: The remote control module 10 of the genuine vehicle remote control is physically and electrically connected to the Bluetooth relay controller 20.

[0015] S02: The Bluetooth relay controller 20 receives the Bluetooth signal transmitted from the mobile terminal 30.

[0016] S03: The Bluetooth relay controller 20 generates a control signal based on the Bluetooth signal and outputs it to the remote control module 10.

[0017] S04: The remote control module 10 controls the vehicle based on the control signals and performs the corresponding operations.

[0018] As shown in Figure 2, the flow of the Bluetooth relay remote control method of the present invention can be realized by the apparatus shown in the figure, and the Bluetooth relay remote control device for a vehicle remote control according to the present invention includes a remote control module 10 and a Bluetooth relay controller 20 that can wirelessly communicate with a mobile terminal 30.

[0019] The remote control module 10 is a circuit module of the original key remote control and includes a first circuit board 11, a processor 12 provided on the first circuit board 11, and a signal transmission circuit 13 provided on the first circuit board 11. The processor 12 can receive touch signals from the function buttons of the original key remote control, and these function buttons are used to control the vehicle and perform corresponding operations, such as locking, unlocking, opening doors, opening the trunk, etc. In this way, the processor 12 controls the signal transmission circuit 13 to transmit a wireless signal based on the received touch signal, and causes the corresponding parts in the vehicle to perform the function corresponding to the function button. However, in the present invention, it is not necessary for the user to press these function buttons. Also, in other embodiments, these function buttons may not be provided on the first circuit board 11.

[0020] The Bluetooth relay controller 20 is a signal relay transmission device between the mobile terminal 30 and the remote control module 10, and is used to transmit operation commands sent from the mobile terminal 30 to the remote control module 10. In one embodiment, the remote control module 10 is substantially coupled to the Bluetooth relay controller 20 and is electrically connected to the Bluetooth relay controller 20.

[0021] Moreover, the Bluetooth relay controller 20 includes a second circuit board 21, a Bluetooth processor 22, a Bluetooth transceiver module 23, and a signal output circuit 24. The Bluetooth processor 22, the Bluetooth transceiver module 23, and the signal output circuit 24 are provided on the second circuit board 21. In one embodiment, the first circuit board 11 of the remote control module 10 is mounted on the second circuit board 21.

[0022] The Bluetooth transceiver module 23 is electrically connected to the input end of the Bluetooth processor 22 and performs wireless transmission of Bluetooth signals to an external mobile terminal 30.

[0023] The signal output circuit 24 is electrically connected to the output end of the Bluetooth processor 22 and the first circuit board 11, and outputs a control signal to the processor 12 of the remote control module 10.

[0024] Furthermore, in one embodiment, it is not necessary to provide a battery in the remote control module 10, and the Bluetooth relay controller 20 determines whether to supply power to the remote control module 10. The Bluetooth relay controller 20 may be provided with internal components of the Bluetooth relay controller 20 and a battery 25 for supplying power to the remote control module 10. In other embodiments, the Bluetooth relay controller 20 may be connected to a DC power outlet inside the vehicle, receive DC power from the vehicle, and be provided with a charging port 26 for supplying power to the Bluetooth relay controller 20 and the remote control module 10.

[0025] The mobile terminal 30 may be a user's mobile phone or other mobile terminal. The mobile terminal 30 has an application (APP) with at least one operation interface operable by the user installed thereon. Through the application, it can perform binding or authentication with the Bluetooth relay controller 20. Only after passing the binding or authentication is the operation of the Bluetooth relay controller 20 by the mobile terminal 30 permitted.

[0026] When supplying power to the remote control module 10 through the Bluetooth relay controller 20, any one of the following three power supply modes can be selected.

[0027] One, constant power supply: The Bluetooth relay controller 20 constantly supplies power from the battery 25 or the charging port 26 to the remote control module.

[0028] Two, connection power supply: As shown in Figure 3, the Bluetooth relay controller 20 includes a switch module 27 connected between the battery 25 and / or the charging port 26 and the remote control module 10, which can be switched on or off by the Bluetooth processor 22. When the connection between the Bluetooth relay controller 20 and the user's mobile terminal 30 is established, the Bluetooth processor 22 controls the switch module 27 to be switched on to supply power to the remote control module 10. On the other hand, when the connection between the Bluetooth relay controller 20 and the user's mobile terminal 30 is not established, the switch module 27 maintains the off state and does not supply power to the remote control module 10.

[0029] 3. Manual Power Supply Settings: The application's operating interface in the mobile terminal 30 has a setting function that allows the user to manually control the switch module 27 shown in Figure 3 to turn it on or off. When the user sets the switch module 27 to on, power is supplied to the remote control module 10. On the other hand, when the user sets the switch module 27 to off, no power is supplied to the remote control module 10 from the battery 25 or the charging port 26.

[0030] The aforementioned "connected power supply" and "manual setting power supply" can enhance the safety of operating the remote control module 10. Specifically, power is supplied to the remote control module 10 only when the mobile terminal 30 is properly connected to the Bluetooth relay controller 20.

[0031] In actual use, the Bluetooth relay remote control device according to the present invention is permanently placed inside the vehicle, eliminating the need for the user to carry it, thus reducing inconvenience. When the user wants to control the vehicle, they input an operation command via the operation interface of the mobile terminal 30. For example, when an unlock command is issued, the mobile terminal 30 transmits the Bluetooth signal of the operation command to the Bluetooth transceiver module 23. Upon receiving the Bluetooth signal, the Bluetooth processor 22 drives the signal output circuit 24 to generate an unlock control signal and transmit it to the processor 12 of the remote control module 10. The processor 12 then unlocks the vehicle based on the control signal.

[0032] Similarly, when a mobile device transmits different operation commands, such as locking the vehicle or unlocking the doors, the Bluetooth relay controller 20 receives the operation commands and then outputs control signals corresponding to the different functions to the remote control module 10. With this method, even if the user does not need to operate the buttons on the remote control module 10, or even if there are no buttons, the remote control module 10 can still receive different control signals, and the signal transmission circuit 13 can generate the corresponding wireless signals to control the parts of the vehicle.

[0033] The Bluetooth relay remote control technology according to the present invention has the following features.

[0034] 1. Users can operate the original vehicle remote control via a mobile device and perform the functions of the vehicle remote control without making any modifications or damage to the vehicle.

[0035] 2. The vehicle owner can control the vehicle remote control using a mobile device without having to carry the original vehicle remote control, thus avoiding inconvenience caused by losing the vehicle remote control or leaving it inside the vehicle and locking it in. [Explanation of Symbols]
