A vehicle height control system includes an arm including a first end portion connected to a vehicle body and a second end portion coupled to a wheel, a bearing unit fixed to the vehicle body, a crank coupled to the bearing unit, a push rod including a first end portion connected to the crank and a second end portion connected to the arm, and a spring reaction force variable device coupled to the bearing unit and configured to vary reaction force applied to the crank.

Vehicle height control system

A leaf spring suspension includes a knuckle having a wheel to be coupled thereto, a fixed frame positioned on a vehicle body and coupled to the knuckle through a trailing arm, a leaf spring having a first end portion coupled to the knuckle and having a second end portion having a variable support point, and a support unit configured to vary the support point on the second end portion of the leaf spring, wherein the support unit includes a spring support positioned to be brought into contact with the leaf spring, and a spring driver coupled to the spring support and configured to apply driving force to change the position of the spring support, and wherein the spring driver moves the position of the spring support to change the support point on the leaf spring.

Suspension having leaf spring

A suspension includes a knuckle to which a wheel of a vehicle is fastened, a steering drive portion connected to the knuckle, a lower arm positioned at a lower end portion of the steering drive portion and including a first end portion connected to the knuckle and a second end portion connected to a vehicle body frame, a connecting link including a first end portion connected to an upper end portion of the steering drive portion, an upper arm connected to a second end portion of the connecting link, a damper connecting the upper arm and the vehicle body frame, and a push rod including a first end portion connected to the upper arm and a second end portion connected to the lower arm.

Suspension apparatus for vehicle

The present disclosure discloses a preview vehicle height control system and a method of controlling the same. The system includes a monitoring device configured to detect the road surface condition of a driving path of a vehicle, an active suspension configured to adjust a vehicle height, a memory configured to store a plurality of data maps distinguished based on a type of bump, each data map having a vehicle dynamic characteristic as an input and a tuning factor as an output, and a controller configured to derive the tuning factor based on a data map, among the plurality of data maps of the memory, corresponding to the bump detected by the monitoring device, derive a target vehicle height in a form of a Gaussian distribution by substituting the tuning factor, and control the active suspension to follow the derived target vehicle height.
