Patent ID: 8086361

Claim:
A system for outputting instructions when a vehicle is not responding to a roll-angle alert, the system comprising: one or more altitude sensors configured to determine one of altitude above ground level or barometric altitude; one or more roll-angle sensors configured to determine roll-angle of the vehicle; a processor configured to receive the altitude and roll-angle information, determine if a roll-angle alert condition exists based on the received altitude and roll-angle information, and generate a roll-angle alert signal if the roll-angle alert condition exists; and one or more output devices configured to output one or more of an audio or video signal if the processor generated the roll-angle alert signal, wherein the processor is further configured to determine if the roll-angle alert condition still exists after one of a predefined period of time, the vehicle roll-angle is deteriorating away from a desired threshold, or vehicle roll-angle rate is greater than a roll-angle rate threshold, generate a roll-direction signal based upon vehicle position relative to the horizon, if one of the roll-angle alert condition still exists after the predefined period of time, the vehicle roll-angle has deteriorated away from the desired threshold, or the roll-angle rate is greater than the roll-angle rate threshold, respectively, and output the determined roll-direction signal via the one or more output devices.
