  • Publication number: 20060178799
    Abstract: An enhanced roll control system for a vehicle having a controlled damping system and a roll control system. In one aspect, the enhanced roll control system may include a first controller for controlling the roll control system, a second controller for controlling the controlled damping system, and at least one sensor positioned at each corner of the vehicle, the position sensors being in communication with the first and second controllers, wherein signals from the position sensors contribute to the control of the controlled damping system and the roll control system.

  • Publication number: 20050133318
    Abstract: Method for determining a present coil temperature of a coil of a magnetorheological (MR) damper of an operating automotive vehicle, wherein the coil is powered by an output of a controller connected to the coil through a conductor. One step includes calculating a coil-plus-conductor resistance from the voltage and the current of the output of the controller when the controller applies a test current to the coil and the conductor. Another step includes calculating the present coil temperature using at least the coil-plus-conductor resistance and compensating for the resistance of the conductor.
