More Information
Summary:The invention provides a method of controlling at least one magnetorheological damper. The invention also provides a computer usable medium including a program and a suspension control system for achieving the same. The method includes calculating a power input coefficient based on at least one power input characteristic. A power dissipation coefficient is calculated based on at least one power dissipation characteristic. A damper temperature is estimated based on the calculated power input coefficient and the calculated power dissipation coefficient. At least one dampening force characteristic is modulated based on the estimated damper temperature.
