| 20090121398 | ELECTROMAGNETIC SHOCK ABSORBER FOR VEHICLE - An electromagnetic shock absorber including: (a) a wheel-side member; (b) a body-side member movable relative to the wheel-side member; and (c) a damping force generator with an electromagnetic motor including stationary and movable elements movable relative to each other. The damping force generator can generate, based on a force generated by the motor, a damping force acting against a relative movement of the wheel-side member and the body-side member. The motor has an axis extending in a both-members-relative-movement direction as a direction of the above-described relative movement. The stationary element is supported by the wheel-side member via an elastic body, to be movable relative to the wheel-side member in the both-members-relative-movement direction. The electromagnetic motor allows relative movement of the stationary element and the movable element upon movement of the stationary element relative to the wheel-side member. | 05-14-2009 |
| 20100025946 | SUSPENSION SYSTEM FOR VEHICLE - It is an object of the invention to provide a suspension system configured to execute a control for avoiding a state in which an operation of an electric motor which is a power source of an electromagnetic actuator is kept halted at a certain operational position while the motor is generating a motor force. Where a target rotational position of the motor becomes equal to a specific operational position (e.g., a rotational position at which an electrifying current amount of one phase reaches a peak value), a control for shifting the target rotational position by δθ is executed. Where the rotational position of the motor is kept located at the certain position for a time period longer than a prescribed time, a control for changing the rotational position of the motor is executed. According to the present suspension system, it is possible to suppress imbalance in heat generation in the motor and to thereby reduce a load to be applied to the motor. Accordingly, a suspension system with high utility is realized. | 02-04-2010 |
| 20100032912 | SUSPENSION SYSTEM FOR VEHICLE - In a system in which an actuator force to be generated by an actuator is controlled based on a component sum that is a sum of a vibration damping component as the actuator force to be generated in a vibration damping control and a posture control component that is the actuator force to be generated in a body-posture control, a control in which the posture control component is limited so as to be not larger than a limit value is executable. The system ensures the actuator force that should be generated in the vibration damping control by limiting the posture control component, in a situation in which there is a limit in the actuator force that can be generated. Accordingly, a sufficient amount of a damping force can be generated, so that riding comfort of the vehicle and the like is prevented from being deteriorated. | 02-11-2010 |
| 20100230876 | VEHICLE SUSPENSION SYSTEM - A vehicle suspension system including: (a) a suspension spring interconnecting a vehicle body and a wheel; (b) an actuator having an electric motor, such that the actuator is capable of generating, based on a force of the electric motor, an actuator force forcing the body and the wheel toward and away from each other, and causing the generated actuator force to act as a damping force against displacement of the body and the wheel; and (c) a control device for controlling the actuator force generated by the actuator, by controlling operation of the electric motor. The control device is capable of establishing a constant-force generating state in which the actuator force is constantly generated as a constant actuator force by the actuator with supply of an electric power thereto from a battery as an electric power source of the electric motor such that the generated constant actuator force acts in a rebound direction or a bound direction. The control device controls the constant-force generating state, based on a charge state of the battery. | 09-16-2010 |
