  • Predictive vehicle controller
    Patent number: 8135531
    Abstract: Due to time delays, vehicle speed may become difficult to control. A predictive speed controller is configured to receive a desired speed request for a vehicle and simulate vehicle responses according to the desired speed request. A compensation value is derived from the simulated vehicle responses that compensates for the time delays of the vehicle. The actual speed of the vehicle is then controlled according to the compensation value.
    Type: Grant

  • ROBUST CONTROL FOR ENGINE ANTI-STALL
    Publication number: 20110264335
    Abstract: A processing device is configured to identify an initial engine speed of an industrial vehicle and monitor a rate of change in engine speed. A variable hydraulic flow device is configured to vary a hydraulic flow associated with a hydraulic system based, in part, on the rate of change in the engine speed. The engine speed may be maintained at or below the initial engine speed while the hydraulic flow is varied.
