ELECTRO-HYDRAULIC STEERING SYSTEM FOR A MOBILE APPLICATION

摘要

A vehicle steering system including a steering device, a position sensor that senses the position of the steering device, and an electronic control unit in operative communication with the position sensor and configured to control the capacity of a variable capacity pump based on output of the sensor is described herein. The variable capacity pump may be a variable displacement pump and the system may also include an electric displacement control adapted to control displacement of the variable displacement pump. The electronic control unit may be configured to determine a rate of change of the position of the steering device, and generate a capacity command signal for controlling the capacity of the variable capacity pump based on the determined rate of change.
