Embodiment Construction

[0043] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] refer to Figure 8 , provides a flowchart of a damping force control method used in an electronically controlled suspension device according to the present invention.

[0045] Before describing the present invention, several terms are defined as follows:

[0046] The road surface judgment permission "ON" state indicates a state in which a road surface judgment can be made, that is, a road surface judgment permission state. The road surface judgment permission "OFF" state indicates a state in which a road surface judgment cannot be made, that is, a road surface judgment prohibition state. When the road surface is judged as one of a good road surface and a bad road surface, the road surface 1 indicates a bad road surface. More specifically, the "ON" state of road surface 1 represents the first situation, in which case the road surface is ...

Abstract

A method of controlling a damping force in an electronically controlled suspension device based on a judgment reference value for judging a road surface during a running time of a vehicle, wherein a comparison of the judgment reference value with a predetermined threshold is used. And judge the road surface according to the comparison result. Then, the damping force is controlled in response to the road surface judgment. The road surface judgment is maintained for a predetermined road surface judgment holding time.

Description

field of invention [0001] The present invention relates to a method of controlling damping force in an electronically controlled suspension device; in particular, to a method of controlling damping force in an electronically controlled suspension device, wherein not only the acceleration signal edge exceeding a threshold value is used number, and also during vehicle running, in the case of judging the road surface to control the damping force, an appropriate damping force is decided using a hold time for maintaining the road surface judgment. technical background [0002] Generally, the suspension device is connected with the axle of the vehicle body to prevent the vibration and collision from the axle from being directly transmitted to the vehicle body, so it can prevent the vehicle body and goods accommodated therein from being damaged and improve the driving comfort of the vehicle. Moreover, the suspension device transfers the driving force generated by the driving wheels...
