ELECTRIC SUSPENSION CONTROL DEVICE

PURPOSE: An electric suspension control device is provided to reduce the caloric value of an electric motor actuator. CONSTITUTION: An electric suspension control device controls the thrust of electric motor actuators (6, 9) using a thrust instruction value from a controller (27). The controller divides the required thrust value of a required thrust producing part into a low frequency band and a high frequency band using a low frequency filter (29) and a high frequency filter (30). The output values of the low and high frequency filters separately the limit amplitude using a low frequency limiter (31) and a high frequency limiter (32). The output values of the low and high frequency limiters are added in an adding part (33) to be outputted to an inverter (26) as a thrust instruction value.
