  • Active suspension control unit and method
    Patent number: 11052718
    Abstract: An active suspension control unit may include an actuator having an active roll stabilization (ARS) structure to variably adjust response characteristics of a suspension, and a controller for determining a driving situation of a vehicle through information input from a sensor, and determining a final desired control value of the actuator based on a desired relative suspension vertical force value set in advance according to the driving situation and a difference value generated by a difference between left and right wheel's relative suspension vertical velocities.
    Type: Grant
    Filed: May 16, 2019
    Date of Patent: July 6, 2021
    Assignees: Hyundai Motors Company, Kia Corporation
    Inventors: Hui Kwon Lee, Woo Kyun Kim, Min Su Lee
  • Vehicle control system and controlling method thereof
    Patent number: 10836377
    Abstract: Disclosed herein are a vehicle control system and controlling method thereof. The vehicle control system includes a plurality of sensors configured to measure a wheel speed, a steering angle, a yaw rate, and acceleration value, and a controller estimating the state of a vehicle based on the wheel speed, the steering angle, the yaw rate, and the acceleration value and updating a front and rear wheel stiffness of the vehicle when it is determined that the vehicle is running on an asymmetric friction surface from the estimated state of the vehicle.
