Abstract
A suspension control device for a vehicle equipped with suspension dampers variable of damping coefficient, including: a means for storing a group of schedules each having a plurality of information units for controlling the variation of the damping coefficient of the damper; a means for generating a new schedule by hybridizing more than one of the schedules selected from the group according to a predetermined genetic algorithm including mutation based upon a fictionalization that the schedules are living individuals each having the plurality of information units as a set of genes; a means for evaluating each of the schedules under current operation environment of the vehicle to determine the ranking of the schedules in the group in improving a predetermined performance of the suspension; a means for adopting a highest ranked schedule for controlling the damping coefficient of the damper; a means for deleting a lowest ranked schedule to keep the number of the schedules forming the group substantially constant; and a means for generating a control signal for controlling the damper based upon the highest ranked schedule.
