Abstract

A vehicle component moves between a first position exposing a rearward area of a vehicle interior and a second position at least partially concealing the rearward area. A movement detection device senses movement of the vehicle component. A vehicle ignition device within the vehicle body structure is operated by a vehicle operator. A controller is operably connected to the movement detection device, the vehicle ignition device and an alerting device. The controller detects movement of the vehicle component and operation of the vehicle ignition device in predetermined sequences of movement and operation. The controller thereafter determines whether or not the vehicle operator has potentially left an object in the rearward area. In response to determining that the vehicle operator may have left an object in the rearward area of the vehicle interior, the controller provides an alarm signal.

Claims

1. A vehicle activity monitoring apparatus comprising:

a vehicle body structure defining a vehicle interior;

a vehicle front door fixed to the vehicle body structure for movement between an open orientation and a closed orientation;

a front door movement detection device configured to sense movement of the front door;

a vehicle component attached to the vehicle body structure for movement between a first position exposing a rearward area of the vehicle interior and a second position at least partially concealing the rearward area of the vehicle interior;

a movement detection device installed within the vehicle body structure and coupled to the vehicle component sensing movement of the vehicle component between the first position and the second position;

a vehicle ignition device within the vehicle body structure operated by a vehicle operator to control operation of a vehicle engine;

an alerting device configured to provide an alarm signal; and

a controller operably connected to each of the front door movement detection device, the movement detection device, the vehicle ignition device and the alerting device, such that in response to the controller detecting a sequence of events based on movement of the front door via signals from the front door movement detection device, movement of the vehicle component via signals from the movement detection device and detection of operation of the vehicle ignition device, the controller determines whether or not the vehicle operator has potentially left an object in the rearward area of the vehicle interior, and in response to determining that the vehicle operator has potentially left an object in the rearward area of the vehicle interior the controller operates the alerting device to provide the alarm signal to the vehicle operator.

2. The vehicle activity monitoring apparatus according to claim 1, wherein

the vehicle body structure defines at least one front door opening and at least one rear door opening, and

the vehicle component is a rear side door pivotally fixed to the vehicle body structure such that the first position is an open position exposing the rear door opening and exposing the rear area of the vehicle interior, and the second position is a closed position of the rear side door covering the rear door opening.

3. The vehicle activity monitoring apparatus according to claim 2, wherein

the movement detection device is a door switch configured to provide a signal in response to movement of the rear side door.

4. The vehicle activity monitoring apparatus according to claim 1, wherein

the vehicle body structure defines a two-door coupe, and

the vehicle component is a front seat installed within the vehicle interior such that the first position is a retracted orientation with at least a seatback of the front seat moved forward exposing the rear area of the vehicle interior behind the front seat and the second position is a seating orientation in which the seatback of the front seat is oriented for receiving a passenger in a seated position.

5. The vehicle activity monitoring apparatus according to claim 4, wherein

the movement detection device is a seat switch configured to provide a signal in response to movement of at least one of the seatback and a seat section of the front seat.

6. The vehicle activity monitoring apparatus according to claim 1, wherein

the vehicle component is a rear hatch door such that the first position is an open position exposing a cargo area of the vehicle interior and the second position is a closed position at least partially enclosing the cargo area.

7. The vehicle activity monitoring apparatus according to claim 6, wherein

the movement detection device is a door switch configured to provide a signal in response to movement of the rear hatch door.

8. The vehicle activity monitoring apparatus according to claim 1, wherein

the alerting device is installed within an instrument panel within the vehicle interior.

9. The vehicle activity monitoring apparatus according to claim 8, wherein

the alerting device includes a display installed to the instrument panel within the vehicle interior and the alarm signal includes a visual signal provided on the display.

10. The vehicle activity monitoring apparatus according to claim 1, wherein

the alerting device is installed within a keyfob operated by the vehicle operator.

11. The vehicle activity monitoring apparatus according to claim 1, wherein

the alarm signal produced by the alerting device includes at least one or more of the following:

a visual alarm, an audible alarm and a vibratory alarm.

12. A method for operating an activity monitoring apparatus comprising:

detecting movement of a vehicle component of a vehicle body structure between a first position exposing a rearward area of a vehicle interior of the vehicle body structure and a second position at least partially concealing the rearward area of the vehicle interior;

detecting operation of a vehicle ignition device within the vehicle body structure operated by a vehicle operator to control operation of a vehicle engine;

detecting movement of a front door indicating location of the vehicle operator;

determining whether or not the vehicle operator has potentially left an object in the rearward area of the vehicle interior in response to the detecting movement of the vehicle component via signals from the movement detection device and detecting operation of the vehicle ignition device in predetermined sequences of movement and operation; and

providing an alarm signal to the vehicle operator in response to determining that the vehicle operator has potentially left an object in the rearward area of the vehicle interior.

13. The method according to claim 12, wherein

the detecting of the movement of the vehicle component includes the vehicle component being a rear side door pivotally fixed to the vehicle body structure such that the first position is an open position exposing the rear door opening and exposing the rear area of the vehicle interior, and the second position is a closed position of the rear side door covering the rear door opening.

14. The method according to claim 12, wherein

the detecting of the movement of the vehicle component includes the vehicle component being a front seat installed within the vehicle interior such that the first position is a retracted orientation with at least a seatback of the front seat moved forward exposing the rear area of the vehicle interior behind the front seat and the second position is a seating orientation in which the seatback of the front seat is oriented for receiving a passenger in a seated position.

15. The method according to claim 12, wherein

the detecting of the movement of the vehicle component includes the vehicle component being a rear hatch door such that the first position is an open position exposing a cargo area of the vehicle interior and the second position is a closed position at least partially enclosing the cargo area.

16. The method according to claim 12, wherein

the providing the alarm signal to the vehicle operator includes at least one or more of the following:

a visual alarm, an audible alarm and a vibratory alarm.
