摘要： A method and algorithm for semi-active suspension damper control is described. The algorithm controls the damper setting to limit vehicle body movement in terms of body modal velocities of heave, roll and pitch. The main input, body movement, is measured with accelerometers. The control output comprises a request in percent of damper control range. Vehicle speed-dependent minimum and maximum limits are applied. The method includes monitoring vehicle speed and a modal sensing system. A common damping rate for the dampers is determined based upon parameters for speed, heave, pitch, and roll. Each damper is controlled based upon the common damping rate adjusted based upon a location of each of the controllable suspension dampers. The output comprises a single signal, translated to a front and rear setting. The purpose is to always have a balanced setting of the four dampers.
