  • Patent number: 11383575
    Abstract: A method of controlling relative roll torque in vehicles having a front active sway bar and a rear active sway bar is provided. The front active sway bar varies roll torque of a front axle and the rear active sway bar varies roll torque of a rear axle. The method includes monitoring dynamic driving conditions during operation of the vehicle and biasing tire lateral load transfer distribution (TLLTD) relative to the front axle based on the monitored dynamic driving conditions. Positive bias of the TLLTD increases the portion of a total roll torque carried by the front active sway bar. Biasing TLLTD occurs during one or more dynamic bias events triggered as monitored dynamic driving conditions exceed one or more calibrated thresholds.

  • Patent number: 11175667
    Abstract: A vehicle, system and method of operating a vehicle. A sensor for measures a dynamic variable of the vehicle. A processor determines a location of a perceived yaw center (PYC) of the vehicle from the dynamic variable, tracks a desired location of the PYC, and adjusts a control parameter of the vehicle to reduce a difference between the location of the PYC and the desired location of the PYC.

  • Patent number: 11097743
    Abstract: A method and system of controlling a vehicle includes providing a plurality of dynamic state inputs to a controller in the vehicle that is adapted to execute a plurality of control loops and further includes determining an operating mode of the vehicle. Based on the operating mode of the vehicle, a location of an optimum perceived yaw center of the vehicle is determined corresponding to a selected estimation technique using the dynamic state inputs and wherein the estimation technique is selected based upon the determined operating mode of the vehicle. The information related to the location of the optimum perceived yaw center may be used as input for controlling the vehicle in a dynamic state.
