1. A method for deterring undesired movement of a vehicle, the method comprising the steps of:
- sensing whether a vehicle transmission is out of a park position;
determining a non-presence of a driver in a driver seat of the vehicle by an occupant detection system in response to the vehicle transmission being out of the park position;
determining that the vehicle is positioned on an inclined surface;
determining that the vehicle is stationary, but that movement of the vehicle may occur in response to the determination of the non-presence of the driver, the transmission being in the out of park position, and the vehicle being positioned on the inclined surface; and
actuating a vehicle movement prevention device for preventing movement of the vehicle in response to the determination that movement of the vehicle is likely to occur.

Abstract
A movement prevention system preventing undesired travel of a vehicle. A transmission gear sensor senses an out of park position of a vehicle transmission. An occupant detection system senses a presence of a driver in a driver seat of a vehicle in response to the vehicle transmission being out of the park position. A processor determines whether movement of the vehicle is likely to occur in response to a determination of the non-presence of the driver. A vehicle movement prevention device prevents movement of the vehicle in response to the processor determining whether movement of the vehicle is likely to occur.

1. A method for deterring undesired movement of a vehicle, the method comprising the steps of:
-
sensing whether a vehicle transmission is out of a park position; determining a non-presence of a driver in a driver seat of the vehicle by an occupant detection system in response to the vehicle transmission being out of the park position; determining that the vehicle is positioned on an inclined surface; determining that the vehicle is stationary, but that movement of the vehicle may occur in response to the determination of the non-presence of the driver, the transmission being in the out of park position, and the vehicle being positioned on the inclined surface; and actuating a vehicle movement prevention device for preventing movement of the vehicle in response to the determination that movement of the vehicle is likely to occur. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A movement prevention system for a vehicle, the system comprising:
-
a transmission gear sensor sensing an out of park position of a vehicle transmission; an occupant detection system sensing a non-presence of a driver in a driver seat of the vehicle in response to the vehicle transmission being out of the park position; a vehicle-based road incline sensor sensing that the vehicle is on an inclined surface; a processor determining that the vehicle is stationary, but that movement of the vehicle may occur in response to the determination of the non-presence of the driver and the determination that the vehicle is on the inclined surface; and a vehicle movement prevention device preventing movement of the vehicle in response to the processor determining that movement of the vehicle is likely to occur. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method comprising:
-
sensing an out of park position of a vehicle transmission; determining a non-presence of a driver in a driver seat by an occupant detection system in response to the sensed out of park position; determining that the vehicle is positioned on an inclined surface; determining that the vehicle is stationary, but that movement of the vehicle may occur in response to determining a non-presence of the driver and the vehicle being positioned on the inclined surface; actuating a vehicle movement prevention device for preventing movement of the vehicle in response to the likelihood of vehicle movement.
