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.
Claims15
A method of assisting a steering effort in a hydraulic steering system comprising:
- measuring a pressure with a pressure sensor assembly;
- calculating an input torque with a controller;
- measuring at least one vehicle condition with at least one vehicle sensor and sending a vehicle condition signal to the controller;
- determining a current required to operate an actuator with the controller;
- and
- determining an assist torque required with the controller, wherein the assist torque is determined by subtracting a desired torque from a combined torque provided by a driver and a motor.
