Suspension control apparatus

摘要

In a suspension control system according to the present invention, a sky-hook command signal B obtained from velocity data obtained by integrating a sprung mass acceleration alphau from a sprung mass acceleration sensor 9 u and an unsprung mass vibration damping command signal C obtained on the basis of an unsprung mass acceleration alphad detected by an unsprung mass acceleration sensor 9 d are added together to obtain a control signal A for a damping characteristic inverting type shock absorber 6. The control signal A reflects the unsprung mass acceleration alphad that leads in phase by 90° the piston speed. Accordingly, it is possible to compensate for a response delay due to an actuator 11, etc.
