Abstract: The solenoid coil includes a coil having a first end surface and a second end surface on its both ends in an axial direction, a member which is in contact with the first end surface, and has a groove through which the wire material of the coil passes, and an insulating resin formed to coat at least an outer circumferential surface and the second end surface of the coil. The resin with a substantially U-shaped section is continuously coated on at least a part of an inner circumferential surface of the coil via an area from the outer circumferential surface to the second end surface.

Abstract: An object of the present invention is to provide a vehicle motion state estimation device and method that can estimate the vertical motion state amount with high accuracy by taking into consideration vertical force in which the frictional force acting in the front-rear direction or lateral direction of the wheel acts on the vehicle body due to the geometry of suspension. A vehicle motion state estimation device in a vehicle in which a wheel and a vehicle body are coupled via a suspension, the vehicle motion state estimation device including: a vertical motion-caused wheel speed component estimation unit that estimates a wheel speed component caused by vertical motion of the vehicle; a vertical force estimation unit that calculates vertical force in which frictional force of the wheel caused by motion of the vehicle acts on the vehicle body by geometry of the suspension; and a vertical motion estimation unit that estimates a state amount of vertical motion of a vehicle, in which the vertical motion estimation unit estimates a state amount of vertical motion of the vehicle based on a wheel speed component from the vertical motion-caused wheel speed component estimation unit and vertical force acting on the vehicle body from the vertical force estimation unit.
