Abstract

A method of providing a vehicle rear seat reminder using a vehicle rear seat reminder system is provided. The method includes exposing a user input device of the vehicle rear seat reminder system by opening a door of a vehicle. The user input device is accessible to a user with the door in an open condition. The user input device being inaccessible to the user with the door in a closed condition. The user input device is actuated with the door in the open condition thereby initiating an alert program.

Claims

1. A method of providing a vehicle rear seat reminder using a vehicle rear seat reminder system, the method comprising:

exposing a user input device of the vehicle rear seat reminder system by opening a door of a vehicle,

wherein the user input device is accessible to a user with the door in an open condition, the user input device being inaccessible to the user with the door in a closed condition; and

actuating the user input device with the door in the open condition thereby initiating an alert program through user actuation of the user input device;

wherein the alert program is inactive until user actuation of the user input device;

wherein the user input device is on a shut face panel of the door located between an interior panel and an exterior panel of the door that carries a door latch assembly.

2. The method of claim 1 providing a signal to a controller upon actuating the user input device, the controller initiating the alert program in response to the signal.

3. The method of claim 2 comprising the controller receiving engine information from an engine sensor for determining an engine OFF event.

4. The method of claim 3 comprising detecting an engine OFF event using the controller based on the engine information.

5. The method of claim 4 comprising providing a signal to the controller using a door sensor when a driver door is closed after the engine OFF event and the controller initiating a time delay sequence of a preselected period of time in response to the signal from the door sensor.

6. The method of claim 5, wherein the door is a rear door of the vehicle, the method comprising providing an alert if the rear door remains in the closed condition for the preselected period of time using an alarm component.

7. The method of claim 1, further comprising concealing the user input device of the vehicle rear seat reminder system by closing the door of the vehicle.

8. The method of claim 1, wherein the door is a rear door of the vehicle.

9. The method of claim 1, wherein the user input device is connected to the door at a shut face panel of the door.

10. A method of providing a vehicle rear seat reminder system for a vehicle, the method comprising:

providing a user input device at a location on the vehicle such that the user input device is concealed with a rear door of the vehicle in a closed condition and is exposed with the rear door of the vehicle in an open condition; and

providing a signal to a controller of the vehicle to initiate an alert program when the user input device is actuated by a user with the rear door in the open condition;

wherein the alert program is inactive until user actuation of the user input device;

wherein the user input device is on a shut face panel of the door located between an interior panel and an exterior panel of the door that carries a door latch assembly.

11. The method of claim 10, wherein, with the rear door in the closed condition, the user input device located between a shut face panel of the rear door and a body component of the vehicle.

12. The method of claim 11, wherein the body component is part of a door frame.

13. The method of claim 12, wherein the user input device is connected to the door frame.

14. The method of claim 11, wherein the user input device is connected to the rear door at the shut face panel of the rear door.

15. In a vehicle,

a vehicle rear seat reminder system comprising:

a controller;

an engine sensor connected to the controller to provide engine information to the controller for detecting an engine OFF event;

a front door sensor connected to the controller to provide a signal to the controller upon a front door close event; and

a user input device connected to the controller to provide a signal to the controller upon user actuation of the user input device to initiate an alert program,

the user input device being concealed between a rear door of the vehicle and a body component of the vehicle with the rear door in a closed condition;

wherein the user input device is on a shut face panel of the door located between an interior panel and an exterior panel of the door that carries a door latch assembly,

wherein the alert program is inactive until user actuation of the user input device.

16. The system of claim 15, wherein the user input device is exposed with the rear door of the vehicle in an open condition.

17. The system of claim 15, wherein the user input device is connected to a shut face panel of the rear door.

18. The system of claim 15, wherein the user input device is connected to the body component.

19. The system of claim 15 further comprising an alarm component operably connected to the controller for providing an alert when alert conditions are met.

20. The system of claim 19, wherein the controller includes logic that

initiates the alert program upon the controller receiving a signal from the user input device upon user actuation of the user input device with the rear door in the open condition;

detects an engine OFF event using the engine sensor;

detects a front door close event using the front door sensor;

initiates a time delay sequence for a preselected period of time in response to the front door close event; and

provides an alert using the alarm component if a rear door open event is not detected within the preselected period of time using a rear door sensor.
