  • Patent number: 10703408
    Abstract: A method of assisting a steering effort in a hydraulic steering system is provided. The method includes measuring a pressure with a pressure sensor assembly. The method also includes calculating an input torque with a controller. The method further includes measuring at least one vehicle condition with at least one vehicle sensor and sending a vehicle condition signal to the controller. The method yet further includes determining a current required to operate an actuator with the controller.
    Type: Grant

  • Patent number: 10421485
    Abstract: A power steering system includes a steering column assembly, a steering gear assembly, and a pressure sensor, and a torque sensor. The steering column assembly has a steering shaft and the steering gear assembly is operatively connected to the steering shaft. The steering gear assembly has an input shaft that extends through a valve housing and extends into a rack housing. The pressure sensor is arranged to provide a pressure signal indicative of a fluid pressure of at least one of a first cavity and a second cavity disposed within the rack housing.
