Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, it should be noted that although four sets of wheels and shock absorbers are installed on the vehicle, for the sake of brevity, the following description of the embodiment of the present invention only focuses on one set of wheels and shock absorbers.

[0023] figure 1 is a block diagram of an electronically controlled suspension device according to a preferred embodiment of the present invention. Such as figure 1 As shown, the electronically controlled suspension device of the present invention includes a sensing unit 100, a control logic unit 110, a control value receiving unit 120, a travel response control unit 130, and a shock absorber installed between the vehicle body and the axle 160 , an actuating unit 150 for controlling the damping force characteristic of the shock absorber 160 and a travel detecting unit 140 for detecting ...

Abstract

An electronically controlled suspension device comprising a stroke detection unit for detecting a relative displacement of a vehicle body with respect to a wheel shaft; a stroke response control unit for determining an adjustment value of a control command; and an operation according to the adjustment value of the control command to Actuation unit that adjusts the extension or compression damping force of the shock absorber. When the relative displacement is equal to or greater than a first predetermined value, or less than or equal to a second predetermined value, the travel response control unit determines a control command adjustment value for increasing the extension or compression damping force of the shock absorber .

Description

field of invention [0001] The present invention relates to an electronically controlled suspension device, and more specifically relates to an electronically controlled suspension device and a damping force control method, which can be changed by changing The damping force characteristic of the shock absorber prevents the shock absorber from being in a fully extended or fully cushioned state. Background technique [0002] Generally, the suspension device connects the wheel shaft to the vehicle body to prevent the vibration and impact from the wheels from being directly transmitted to the vehicle body, so as to protect the vehicle body and its cargo from damage and improve the ride comfort of the vehicle. Also, the suspension device transmits driving force generated from driving wheels to the vehicle body or braking force of the wheels when braking the vehicle to a stop, bears centrifugal force generated during the turning motion of the vehicle and maintains precise positions...
