MACHINE LOSS-OF-CONTROL DETECTOR AND SHUTDOWN SYSTEM
First Claim
1. A method of machine loss of control detection comprising:
- detecting intended motion of the machine or a part of it;
detecting actual motion of the machine or the part of it; and
determining machine loss of control in response to whether actual motion is materially different from intended motion;
wherein the step of detecting actual motion is responsive to angular motion signals from a gyroscopic angular sensor and, optionally, linear motion signals from at least one accelerometer.

Abstract
A method and system are described for machine loss of control detection. Intended motion (e.g. from a human operator or automatic control system) of the machine or a part of it is detected. Actual motion of the machine or a part of it is detected. Machine loss of control is determined in response to whether actual motion is materially different from operator intended motion. Actual motion is determined from angular motion signals from a gyroscopic angular sensor and, optionally, linear motion signals (e.g. acceleration via one or more accelerometers). Machine loss of control determination may be used to stop the actual motion (e.g. stopping power or fuel an engine, bypassing hydraulic fluid flow, etc). The method and system are adaptable to machines having one or more driving and actuating systems capable of malfunctioning in such a way as to cause the machine to move uncontrollably.

9. A system for determining machine loss of control comprising:
-
one or more controllers having one or more inputs for receiving indications of intended motion of the machine or a part of it and actual motion of the machine or a part of it and at least one output, said one or more controllers configured to detect said intended motion and actual motion and determine machine loss of control in response to whether actual motion is materially different from operator intended motion; and wherein, for detecting the actual motion, at least one of said inputs receives angular motion signals from a gyroscopic angular sensor. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
