Abstract

Embodiments of method performed in conjunction with a vehicular garage door control system are provided, as are embodiments of a vehicular garage door control system and a program product executed by a smartphone in communicating with such a garage door control system. The vehicular garage door control system may include an in-vehicle Garage Door Opener (GDO) signal generator, a wireless receiver, and a controller. In one embodiment, the method includes receiving, at the controller via the wireless receiver, a request signal originating from a remote electronic device requesting actuation of a GDO unit that, when actuated, moves a garage door between open and closed positions. In response to receipt of the request signal, a command signal is supplied from the controller to the in-vehicle GDO signal generator commanding the in-vehicle GDO signal generator to generate a GDO actuation signal requesting actuation of the GDO unit.

Claims

1. A method performed in conjunction with a vehicular garage door control system including an in-vehicle Garage Door Opener (GDO) signal generator, a camera, a wireless receiver, and a controller operatively coupled to the in-vehicle GDO signal generator, to the camera, and to the wireless receiver, the method comprising:

receiving, at the controller via the wireless receiver, a request signal originating from a remote electronic device requesting actuation of a GDO unit that, when actuated, moves a garage door between open and closed positions;

in response to receipt of the request signal, supplying a command signal from the controller to the in-vehicle GDO signal generator commanding the in-vehicle GDO signal generator to generate a GDO actuation signal requesting actuation of the GDO unit;

after generation of the GDO actuation signal by the in-vehicle GDO signal generator, receiving, at the controller, a picture or streaming video feed of an area in front of or behind the vehicle, as captured by the camera; and

transmitting the picture or streaming video feed from the controller to the remote electronic device for presentation on a display thereof.

2. The method of claim 1 wherein the request signal is transmitted from the remote electronic device to the wireless receiver over a wireless network.

3. The method of claim 2 wherein the remote electronic device comprises a smartphone, and wherein the request signal is transmitted from the smartphone to the wireless receiver over a cellular network when the smartphone is executing a software application and user input is received requesting actuation of the GDO unit.

4. The method of claim 2 further comprising:

determining, in the controller, if a change in garage door position has occurred; and

transmitting data from the controller, over the wireless network, to the remote electronic device data indicative of the change in garage door position.

5. The method of claim 4 further comprising supplying a command signal from the controller to the in-vehicle GDO signal generator commanding the in-vehicle GDO signal generator to generate a second GDO actuation signal if a garage door position change is not detected after generation of a first GDO actuation signal.

6. The method of claim 4 wherein the vehicular garage door control system comprises an obstacle detection sub-system deployed onboard the vehicle and operatively coupled to the controller, and wherein the method further comprises determining, in the controller, the position of the garage door utilizing the obstacle detection sub-system.

7. The method of claim 4 wherein the data transmitted from the controller, over the wireless network, to the remote electronic device data is indicative of the current detected position of the garage door.

8. The method of claim 4 wherein the data transmitted from the controller, over the wireless network, to the remote electronic device data indicates that a change in the position of the garage door has occurred after generation of the GDO actuation signal.

9. The method of claim 1 further comprising a telematics module deployed onboard the vehicle and including the receiver and the controller.

10. The method of claim 1 wherein the vehicular garage door control system further comprises a Remote Keyless Entry (RKE) module operatively coupled to the controller, wherein the receiver is included within the RKE module, and wherein receiving comprises receiving via the RKE module a request signal requesting actuation of the GDO unit from a keyfob.

11. The method of claim 10 further comprising identifying in the controller the request signal based at least partially upon the pattern of signals received from the keyfob, the duration of signals received from the keyfob, or a combination thereof.

15. The method of claim 4 further comprising:

repeatedly generating the GDO actuation signal until a garage door position change is detected or until a predetermined number of actuation attempts is exceeded; and

if the predetermined number of actuation attempts has been exceeded, transmitting an error signal to the remote electronic device over the wireless network.

12. A vehicular garage door control system for use in conjunction with a keyfob and a garage door opener (GDO) unit utilized to move a garage door between open and closed positions, the vehicular garage door control system comprising:

an in-vehicle GDO signal generator configured to generate a garage door actuation signal recognized by the GDO unit;

a Remote Keyless Entry (RKE) module including a wireless receiver configured to receive a wireless signal from keyfob requesting actuation of the GDO unit; and

a controller operatively coupled to the in-vehicle GDO signal generator and to the wireless receiver of the RKE module, the controller commanding the in-vehicle GDO signal generator to generate a garage door actuation signal when the wireless receiver receives a wireless request signal from the keyfob requesting actuation of the GDO unit;

wherein the controller identifies the wireless signal originating from the keyfob requesting actuation of the GDO unit based upon the pattern or duration of a signal transmitted from the keyfob when an input dedicated to a different type of function is actuated by a user of the keyfob.

13. A program product executable by a smartphone configured to communicate with a vehicular garage door control system over a wireless network, the program product comprising:

a smartphone software application comprising computer-readable instructions to;

generate on a display of the smartphone a virtual control enabling a user to request generation of a garage door opener (GDO) actuation signal by the vehicular garage door control system to open or close a garage door;

determine when the virtual control has been selected;

when the virtual control has been selected, transmit a request signal over the wireless network to the vehicular garage door control system requesting generation of the GDO actuation signal;

receive from the vehicular garage door control system a picture or streaming video feed of an area in front of or behind the vehicle, as captured by a camera included in the vehicular garage door control system; and

display the picture or streaming video feed on the display of the smartphone to enable the user to determine the position of the garage door; and

non-transitory computer-readable media bearing the smartphone software application.

14. The program product of claim 13 wherein the smartphone software application further comprises instructions to produce on the display of the smartphone a visual indication of the current position of the garage door, as detected by the vehicular garage door control system.

16. The program product of claim 13 wherein the smartphone software application further comprises instructions to automatically send a request to the vehicular garage door control system for a picture or streaming video feed of an area in front of or behind the vehicle upon initial execution of the software application.
