Latest Patents

One of Griesbach's latest patents is a draft control method for operating an earth-moving machine. This invention involves a hydraulic actuator that moves the hitch on a vehicle. The method defines a draft force setpoint by averaging two forces acting on the lateral sides of the hitch while in configuration mode. During regular operation, a draft load is calculated from these forces, and a draft force error is derived from the difference between the draft load and the setpoint. This error is then used to control fluid flow to and from the hydraulic actuator, enhancing operational efficiency. Another notable patent is for an active vehicle suspension system that isolates the operator cab from vibrations in the chassis. This system employs hydraulic actuators and accumulators to attenuate high-frequency vibrations, ensuring a smoother ride for the operator.
