  • Patent number: 8844943
    Abstract: Disclosed herein is an electronic control suspension (ECS) system for vehicles. The ECS system includes a strut assembly which is coupled to a vehicle body and a lower portion of which is inserted through the housing to absorb the rocking from the wheel. The system further includes a vehicle height control module at a lower portion of the strut assembly, wherein the control module includes a spiral guide groove formed in the strut assembly and a guide member fitted into the guide groove. The guide member is rotated using a motor to move the guide member along the guide groove to cause the strut assembly to be moved vertically to control the height of a vehicle.

  • Patent number: 8833775
    Abstract: An electronic control suspension (ECS) system for vehicles is provided. The ECS system includes a strut assembly which is coupled to a vehicle body, and a lower portion of which is inserted through the housing so as to absorb the rocking from the wheel. A vehicle-height control module converts a rotating force of a motor to a linear motion of the strut assembly when the rotating force of the motor is provided to a screw section thereof surrounding the stmt assembly. This allows the strut assembly to be vertically moved relative to the housing, thereby controlling the height of a vehicle.
