Abstract

A method and system prevents accidental direction selection in a motor vehicle. The driver of the vehicle is alerted that the selected direction of the vehicle via the gear shift is opposite of the direction that the driver intends for the vehicle to move. The selected direction of the vehicle by the driver is initially detected. The invention then detects the driver'"'"'s physical position and any objects in the immediate area surrounding the vehicle. Based on the information gathered from these detections, there is determination made regarding the vehicle direction selected by the driver. If the determination is the likelihood of an accident/collision if the vehicle moves in the selected direction, the present invention will alert the driver. In addition, an embodiment of the present invention may also include the ability to disable the vehicle in order to avoid a collision.

Claims
