    摘要: A method and system are described for machine loss of control detection. In one aspect, the method and system detect operator intended motion of the machine or a part of it and actual motion of the machine or a part of it; and determine machine loss of control 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.

    摘要: A method and system are described for calibrating speed controls for a vehicle having a pair of drive means on opposite sides of the vehicle driven by independent speed controls and where relative speed of the drive means is used to direct the vehicle. In one aspect, angular motion of the vehicle is detected using at least one of a gyroscopic angular sensor and a pair of accelerometers to determine a rate of yaw; a speed control output for controlling the relative speed is adjusted so that the rate of yaw is lower than a threshold when speed control inputs for controlling the relative speed are equal; and one or more speed control adjustment parameters are determined and stored for use during operation for controlling the relative speed of the drive means. A microcontroller may be used to receive sensor outputs (e.g. from the gyroscope and/or accelerometers) and speed control inputs and to determine the speed control adjustment. During operation, the microcontroller may control the relative speed, applying the speed control adjustment(s) to speed control inputs.
