This application claims the benefit of Korean Patent Application No. 10-2021-0116063, filed on Sep. 1, 2021, which application is hereby incorporated herein by reference.
The present disclosure relates to a door control system and method for a vehicle.
A camping activity, where people can rest in nature, has received a lot of attention from the old days as a leisure activity. Conventionally, camping meant spending time at a mountain, a beach, etc., with a tent. Recently, auto-camping using a sports utility vehicle (SUV), a recreational vehicle (RV), or the like, is also drawing attention.
In auto-camping, campers may enjoy camping with a tent, tarp, or lantern hung on a door or a tailgate of a vehicle. Camping equipment, food, etc., may be placed on an extension deck or an outdoor multi-level luggage board in a trunk room with the door or the tailgate opened.
In a vehicle with a power door, for example, a power tailgate on the rear of the vehicle can be automatically opened or closed by operating a remote key of the vehicle, such as a smart key, or a button provided on the tailgate side. An accident may occur if the smart key or the tailgate button is incorrectly operated by the user's negligence, etc., during camping with the tailgate opened. The tailgate closes automatically, which can injure people or damage objects.
To prevent such safety accidents, there is a need for a countermeasure enabling the door, such as the tailgate of the vehicle, to be kept open in spite of misoperation of the smart key or the button.
The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure and accordingly it may include information that does not form the prior art that is already known to a person of ordinary skill in the art.

As a non-limiting example, the out-vehicle switch 24 may be a key of the vehicle including a smart key wirelessly connected and exclusively communicating with a specific vehicle. As another non-limiting example, the out-vehicle switch 24 may be a mobile device that may nonexclusively communicate with the vehicle 1, such as a smart phone or a tablet device wirelessly connected to the vehicle 1. For example, when the mobile device and the vehicle 1 are paired, the mobile device may be configured to open or close the door 10 through a designated application.
The door control system according to embodiments of the present disclosure includes a controller 30. The controller 30 may be configured to receive an input from at least one switch 20 and to allow the door 10 to be operated based on the received input. According to an embodiment of the present disclosure, the controller 30 includes a communication unit 32 and a memory unit 34.
The controller 30 is configured to communicate with the at least one switch 20 through the communication unit 32. The controller 30 may receive input information of the in-vehicle switch 22 through the communication unit 32. Further, the controller 30 may be wirelessly connected to the out-vehicle switch 24, such as the smart key or the mobile device, to receive the input information through the communication unit 32. As a communication method between the controller 30 and the switch 20, a known connection method may be used and, therefore, the description thereof will be omitted.
The memory unit 34 is configured to store instructions executable by the controller 30. The controller 30 is configured to execute the instructions stored in the memory unit 34 with respect to a specific input by the switch 20 to perform a series of steps.
The controller 30 is configured to communicate with an interaction unit 50. A control mode of the door may be changed based on data input by the interaction unit 50. In an embodiment, the interaction unit 50 is a user interface provided on the instrument cluster of the vehicle to enable the user to change various settings of the vehicle. In another embodiment, the interaction unit 50 may be the mobile device configured to communicate with the controller 30 of the vehicle. When the user selects a specific setting through the interaction unit 50, the controller 30 may be operated based thereon. For example, the interaction unit 50 may be provided with a settings window of a keep-open mode to be described later.
A vehicle interior is provided with a room lamp 40. As a non-limiting example, the room lamp 40 may be provided on a rear portion of a headlining inside the vehicle. The room lamp 40 is provided to secure visibility inside the vehicle 1. The room lamp 40 may maintain the turned-on state if the door 10 is opened. According to embodiments of the present disclosure, the room lamp 40 may be turned on or off and the brightness thereof may be adjusted based on the user's input, more specifically, the user's input through the interaction unit 50. As described below, for example, the user's selection about the room lamp 40 may be input through the interaction unit 50, and the controller 30 may control the room lamp 40 depending upon the user's input.
Basically, a closing operation of the power door of the vehicle is shown in a flowchart of
Hereinafter, a door control method according to the door control system according to embodiments of the present disclosure will be described.
As shown in
The closing of the door 10 is input to the controller 30 through the switch 20 (S110). According to embodiments of the present invention, the keep-open mode may be set to prevent the door 10 from being accidentally closed. For instance, although the user does not intend to close the door 10, the user may operate the switch 20 negligently or incorrectly.
Therefore, the controller determines whether the keep-open mode is in an ON state if the door closing request is input (S120). As described above, setting the keep-open mode may be implemented through the interaction unit 50. Alternatively, setting the keep-open mode may also be configured to be implemented through the mobile device communicable with the vehicle. The keep-open mode refers to a settings mode in which the door 10 is not closed immediately even when closing is input through the switch 20 in the opened state. Therefore, it is possible to prevent the door 10 from closing due to the incorrect operation in camping, etc.
When receiving the closing input by the switch 20 when the keep-open mode is selected, the controller 30 first maintains the door 10 in the opened state (S130). At the same time, the controller outputs a guidance message to the interaction unit 50, the mobile device, etc. (S130). The message may be a voice message, a text message, or a combination thereof. For example, the message may be “In the keep-open mode. To cancel the keep-open mode, please press and hold the switch 20 for 3 seconds.” In other words, the controller outputs a preset message.
If there is no input by the user after the preset message is output, the door 10 is maintained in the opened state.
Conversely, when the user acts on output preset message after the message is output, the controller 30 closes the door 10 in accordance with the user's closing input. In other words, the controller 30 determines whether there is an additional operation by the user after the message is output (S140). In the above example, when the user presses and holds the switch 20 for 3 seconds and then presses the closing button again through the operation of the switch 20, then the controller 30 closes the door 10. If the user presses and holds the switch 20 for 3 seconds to cancel the keep-open mode, a message which notifies cancellation of the keep-open mode may also be output to the interaction unit 50 or the mobile device. Then the user may operate the switch 20 to close the door 10 (S150). In other words, when the user presses the switch 20 for 3 seconds and then the keep-open mode is canceled, the user may make the closing input by manipulating the switch 20 again to close the door 10.
Further, according to embodiments of the present disclosure, the controller 30 is configured to adjust the ON/OFF status and brightness of the room lamp 40. As shown in
The controller 30 according to embodiments of the present disclosure may be a single controller and may comprise multiple controllers. For example, one controller may be configured to control opening or closing of the door or the operation of the room lamp. Further, multiple controllers may also control the opening or closing of the door and the operation of the room lamp, respectively.
According to embodiments of the present disclosure, it is possible to implement the function by adding only the logic without increasing cost or weight caused by addition of the physical structure, thereby economically improving the merchantability of the vehicle.
Further, according to embodiments of the present disclosure, it is possible to prevent a safety accident that can occur in relation to the unintentional closing of the conventional tailgate.
The aforementioned present disclosure is not limited to the aforementioned exemplary embodiments and the accompanying drawings, and it will be apparent by those skilled in the aft to which the present disclosure pertains that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present disclosure.
