Abstract
A control method of active suspension system, called Preview Control, applying road-surface profile measured in advance, is advocated. However, it is difficult to detect accurate road-surface profile for practical application, because no sensor can detect road-surface profile directly in general. This problem is unavoidable for a non-contact laser displacement sensor installed on the automobile active suspension system. This paper proposes a new method to estimate road-surface profile by the full-order observer, which uses body vertical acceleration, suspension stroke, lateral acceleration, longitudinal acceleration, actuator angle, and relative distance between road-surface and laser displacement sensor. Moreover, this method is applied to an electric active suspension system, and then improvement of comfortability in riding and decrease of energy consumption are verified.
