FIG. 1A is a perspective view illustrating the positions of a camera unit and a door opening sensor outside a vehicle according to an exemplary embodiment of the present invention.
FIG. 1B is a perspective view illustrating the positions of an around view mode switch and a screen in the vehicle according to the exemplary embodiment of the present invention.
Referring to FIGS. 1A and 1B, in the control method for an around view stop mode, a camera 11 may be provided on an exterior of a vehicle 10 and a door opening sensor 12 may be included in one side of a vehicle door.
The camera 11 is provided on a front side, a rear side, and lateral sides outside the vehicle 10 and may photograph the exterior of the vehicle 10.
In this case, the camera 11 may adopt a superangle lens so as to photograph a maximum wide location, and flection may occur on a screen photographed by the lens due to a wide view angle, and images are composited so as to make the flection be shown flat and the composite image is transmitted to a monitor.
Meanwhile, the camera 11 is provided on the exterior of the vehicle 10, and a camera cover member may be formed on one side of the camera 11 so as to prevent the camera 11 from being damaged due to external impacts.
In this case, the camera cover member keeps a state in which a cover is closed so as to protect the camera 11 when the vehicle 10 is driven at a predetermined speed or more, and the cover member may be opened when the occupant intends to check the exterior of the vehicle 10 by using the camera 11.
The door opening sensor 12 is provided on one side of the door and may check whether the door is opened or closed.
A type of the door opening sensor 12 is not limited. For example, the door opening sensor 12 may be formed to sense an opening/closing state of the door by the pressure of the door of the vehicle 10 and may be formed to sense the opening/closing state of the door by the position of the door of the vehicle 10.
Meanwhile, the door opening sensor 12 senses whether the door is opened or closed to transmit the sensed opening/closing state to a monitor 14 to be described below.
In the around view mode, images photographed by the cameras 11 attached on front, rear, and lateral sides of the vehicle 10 are transmitted to the monitor to easily stop the vehicle 10.
In this case, an around view mode switch 13 is provided inside the vehicle 10, and when the occupant intends to operate the around view mode, the occupant presses the switch to operate the around view mode. However, a method of operating the around view mode by pressing a button is not limited. For example, the around view mode switch 13 may be operated by a rotary plug or the around view mode switch 13 may be operated by a touch panel. However, in FIG. 1B, a pressurized button is provided for easily understanding the present invention.
Meanwhile, when the around view mode switch 13 is operated, the camera 11 photographs a situation outside the vehicle 10 and the photographed images may be transmitted to the monitor 14.
The monitor 14 may be provided inside the vehicle 10 so as for the occupant to check the image photographed by the camera 11 with his/her naked eyes.
In detail, the monitor 14 is formed to be positioned at the center between a driver seat and a passenger seat to allow both a driver and an occupant who sits on the passenger seat to monitor the monitor 14.
Meanwhile, the monitor 14 may serve as a navigation display that may display a path guide for general driving and may show a screen of the exterior of the vehicle 10 photographed by the camera 11 when entering the around view mode.
FIG. 2 is a flowchart illustrating a control method for an around view stop mode according to an exemplary embodiment of the present invention.
Referring to FIG. 2, a control method for an around view stop mode includes stopping (S10), changing a gear to a P state or a parking brake to a brake-on state (S30), and outputting an image from a monitor (S70-1, S70-2, S70-3, and S70-4).
In the act of stopping (S10), an occupant operates an around view mode by pressing an around view mode switch 13 in order to stop a vehicle 10, and when the around view mode is operated, an image photographed by a camera 11 provided on an exterior of the vehicle 10 is output to a monitor 14 to safely stop the vehicle 10.
In the changing of the gear to the P state or a parking brake to the brake-on state (S30), when the gear of the vehicle 10 of which stopping is completed is changed to the P state or the parking brake is used, the around view mode may be switched to a stop mode.
In detail, when the gear of the vehicle 10 is positioned at a D, R, or N state, the around view mode is operated so as to easily stop the vehicle and when the gear of the vehicle 10 is positioned at the P state or the parking brake is used, the around view mode is changed to the stop mode to operate.
In this case, in the stop mode, when it is sensed that the door of the vehicle 10 is opened by a door opening sensor 12, a getting-on/off view screen may be output from the monitor 14, while when the opening of the door of the vehicle 10 is not sensed, a navigation screen may be output onto the monitor 14.
A detailed stop mode may be operated by four methods including outputting a top view and a rear view from the monitor (S70-1), outputting a left view and the rear view from the monitor (S70-2), outputting a right view and the rear view from the monitor (S70-3), and outputting the navigation screen from the monitor (S70-4).
The outputting of the top view and the rear view from the monitor 14 (S70-1) occurs when opening of a left door (S40) and opening of a right door (S60) are sensed by a door opening sensor 12 for the door of the vehicle 10, and the top view to check left and right situations of the vehicle 10 and the rear view to check a rear situation of the vehicle 10 may be output on the monitor 14.
The outputting of the left view and the rear view from the monitor 14 (S70-2) occurs when the opening of the left door (S40) is sensed, but the opening of the right door (S60) is not sensed by the door opening sensor 12 for the door of the vehicle 10, and the left view to check the left situation of the vehicle 10 and the rear view to check the rear situation of the vehicle 10 may be output on the monitor 14.
The outputting of the right view and the rear view from the monitor 14 (S70-3) occurs when the opening of the left door (S40) is not sensed, but the opening of the right door (S60) is sensed by the door opening sensor 12 for the door of the vehicle 10, and the right view to check the right situation of the vehicle 10 and the rear view to check the rear situation of the vehicle may be output on the monitor 14.
The outputting of the navigation screen from the monitor 14 (S70-4) occurs when the opening of the left door (S40) is not sensed and the opening of the right door (S50) is not also sensed by the door opening sensor 12 for the door of the vehicle 10, and it is determined that an occupant does not get on or off the vehicle 10 to output an existing navigation screen.
As described above, exemplary embodiments of the present invention have been described, but it will be appreciated by those skilled in the art that the present invention may be modified and changed in various ways by the addition, change, deletion or addition of constituent elements without departing from the spirit of the present invention described in the claims, and that the modifications and changes are included in the claims of the present invention.
