Title:

VEHICLE SUSPENSION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2007/108316

Kind Code:

A1

Abstract:

A suspension system includes an actuator having an electric motor and generating an actuator force as a force in the direction of approach/departure between wheels and a vehicle body. When the charge state of a battery which supplies power to the motor is in a highly charged state, in order to consume power from the battery so as to dissolve the battery highly charged state, the suspension system executes a highly charged state time control by forcibly realizing a state (stationary force generation state) for generating a stationary force FG which is a stationary actuator force for vertically moving the vehicle height. When the highly charged state time control is executed, in almost all the time while the control is executed, the actuator force FA is generated and the motor receives electric power from the battery to generate an actuator force, thereby effectively consuming the battery power.
