VEHICLE DOOR CONTROL SYSTEM

BACKGROUND OF THE INVENTION

The present invention relates to a vehicle door control system with a touch panel display.

Vehicles comprise opening/closing members such as a plurality of doors, a trunk lid and a window glass in each of the doors. In the doors, in order to enhance vehicle accesibility of passengers, it is suggested to provide a vehicle control system for a vehicle door in which an electric door opening device with a power source such as a motor is driven to open and close a selected door electrically.

For example, in a vehicle door control system in JP2016-16813A, a vehicle door image on a touch panel display is selected by touching, and a touched finger slides to open and close a door. An electric door opening device is actuated to open or close the door, so that the door selected by the touch panel display is opened or closed.

In the vehicle door control system in JP2016-16813A, a user who operates the touch panel display is a driver at a driver's seat, and the operated door is a rear door. The operated door is behind the user, and if the touch panel display is operated to open the door without making sure backward, the rear door will be opened unexpectedly, so that a passenger at a rear seat is likely to get uncomfortable.

SUMMARY OF THE INVENTION

In view of the disadvantage, it is an object of the present invention to provide a vehicle door control system by which a door is safely opened by touching a touch panel display.

Then, procedures for operating the object using the touch panel display 14 in this embodiment will be described with a flow chart in FIG. 12.

The following description in FIG. 12 relates to the door 2C as the operating object, and can also be understood with respect to another door instead of the door 2C.

On the touch panel display 14 in which a map information of the navigation device is displayed, a certain display portion is touched, and the initial picture A in FIG. 3 is displayed on the touch panel display 14 as STEP S1.

“DOOR” is selected on the operating object selection area “a” in the initial picture A. With judgment in STEP S2, if it is determined that the door 2C is closed, it goes to STEP S3, and the operation object picture B1 in FIG. 4 is shown on the touch panel display 14. On the operating object picture B1, the area c for the door 2C shows that “DOOR OPEN”, and “DOOR LOCK”, “DOOR MIRROR”, “WINDOW GLASS” and “SEAT ADJUSTMENT” except “DOOR” get dark on the operating object selecting area “a”.

Then, the open extent adjusting portion “d” shown in the right-side operating object picture B1 is touched to adjust an open extent of the door, and then, the selection portion “c” for “DOOR OPEN” for the right-side door 2C of the plurality of selection portions “c” for “DOOR OPEN” is touched and determined in STEP S5.

If it is determined that the door 2C can be opened safely, by the judgment at a next step S8 or if the obstacle sensor 18 does not detect an obstacle in parking at ON of a parking range or at vehicle speed of less than 3 km/h, it goes to an operating object screen B3 In FIG. 6 and displays “DOOR OPENS” at a reporting part “e” of the touch panel display 14 to inform the user of alphabetic information that the door 2C opens.

Simultaneously with report of the alphabetic information displayed on the touch panel display, the control device 17 performs voice report control by which if is created through a voice that “RIGHT REAR DOOR OPENS” and informs a rear-seat passenger through the voice that the door 2C opens.

If the control device 17 determines that that the door 2C cannot securely be opened at the judgment process in the step S8 or if the obstacle sensor 18 detects an obstacle that the door 2C cannot be opened to make it impossible to get in or out of the vehicle or to make the vehicle run at speed over a predetermined speed, the report part “e” of the touch panel display 14 displays a message such as “THERE ARE AN OBSTACLE” or “STILL RUNNING” to inform one alphabetically that the door 2C cannot be opened and to make it impossible to open the door 2C owing to the electric door opening device 6C.

At the reporting process of the step S7, the user touches a determining portion f of the operating object screen B3 after one confirms safety, and a coordinate signal on the touched position or a door-opening signal is transmitted to the control device 17. The control device 17 drives and controls a releasing actuator (not shown) of the door 2C based on the door-opening signal from the touch panel display 14 and releases the door lock device of the door 2C, and then starts opening control for driving the electric door opening device 6C for the door 2C at a rotating amount corresponding a door-opening extent determined at an opening-extent adjusting portion “d” at the step S8.

The door 2C is opened at the step S9 by the electric door opening device 6C, and a pulse signal corresponding to an opening extent of the door 2C is transmitted to the control device 17 from an angular sensor of the electric door opening device 6C, Before the door 2C starts opening, the voice is formerly given from a loudspeaker 15 at the step S7 that the door 2C is opened, so that the door 2C can safely be opened without discomfort to the rear-seat passenger.

The control device 17 performs arithmetic calculation on the basis of the pulse signal transmitted from the angular sensor to find a moving direction and an opening position of the door 2C, so that image data for the opening position is transmitted to the touch panel display 14. Based on image data from the control device, the touch panel display 14 displays an animation on the operating object screen B3 as if a door image like the door 2C opens. Hence, the user can make sure on the touch panel display 14 that the door 2C opens.

If the obstacle sensor 18 does not detect an obstacle during opening of the door 2C in judgment of the step S10, the control device 17 compares a present door position calculated based on a pulse signal from the angular sensor with a predetermined open extent, and keeps door opening control if the present door position does not reach the predetermined open extent. The control device 17 stops the electric door opening device 6c if it is determined that the door reaches a predetermined open position at the step S11. Hence, the door 2C stops at the predetermined open position of the step S12.

If the obstacle sensor 18 detects an obstacle during judgment at the step S10, the electric door opening device 6C is controlled even before the door 2C reaches the predetermined open position, so that the door 2C is stopped just before the predetermined open position at the step S13.

If it is judged that the door 2C is open during the foregoing judgment in the step S2, it goes, to the step S4 in which an operating object picture B2 in FIG. 5 appears on the touch panel display 14. “DOOR CLOSED” appears on the word display “c” corresponding to the door 2C in the operating object picture B2.

“DOOR CLOSED” at a selecting portion “c” corresponding to the right rear door 2C on the operating object picture B2 is touched at the step 814, and a coordinate signal or a door closing signal for the operating object picture B3 is transmitted to the control device 17. The control device 17 receives the door closing signal from the touch panel display 14 and carries out closing control of the electric door opening device 6C corresponding to the door 2C at the step S15. Hence, the door 2C starts closing at the step S16, and a pulse signal with the number for an open extent of the door 2C is supplied from the angular sensor of the electric opening device 6C.

The control device 17 performs arithmetic calculation based on the information of the pulse signal transmitted from the angular sensor and calculates a moving direction and a door position of the door 2C to transmit image data corresponding to the door position to the touch panel display 14. Anytime, based on pictorial data from the control device 17, the touch panel display 14 displays an animation as if a door image like the door 2C is closed on the operating object picture B4. Hence, the user can make sure on the touch panel display 14 that the door 2C closes.

If the fully-closing switch defects that the door 2C is fully closed at the step S17, the control device 17 carries out stop control of the electric door opening device 6c. Thus, the door 2C stops at the fully-closed position at the step S18.

One embodiment of the present Invention is described as above, and without departing from claims, various modifications and changes may be made as below:

(a) The doors 2A-2D are sliding doors instead of the swinging doors.

(b) The touch panel display 14 is used only for the electric device.
