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 vehicle active suspension system. This paper proposes a new method to estimate road surface profile by the full-order observer, which uses actuator angle, suspension stroke, lateral acceleration, longitudinal acceleration, 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 ride comfort and decrease of energy consumption are verified.
