  • System and method for calibrating a differential steering system
    Patent number: 6702048
    Abstract: A system and method of calibrating a differential steering system in a vehicle is provided. An initiation signal is received. At least one operating condition of the vehicle is monitored. A variable activation signal is applied to an actuation device operable to initiate a flow of pressurized fluid to a steering motor when the at least one operating condition is within a predetermined range. The rotation of the steering motor is monitored. A data point indicative of the value of the variable activation signal applied to the actuation device is captured when the steering motor begins to rotate in response to energization of the actuation device.
