摘要： A tire load calculation section of a controller calculates tire load factors of the respective wheels. A target tire load-factor calculation section calculates a tire load factor average value (ηave) obtained by averaging the tire load factors (ηi) of the respective wheels as a target tire load factor. A target tire vertical-load calculation section calculates target tire vertical loads (Fzrefi) for the respective wheels so that the tire load factors of the respective wheels become equal to the tire load factor average value. A vertical-load control section and a suspension control section control thrusts of electromagnetic dampers for the respective wheels so as to achieve the target tire vertical loads.

摘要： Provided are a vehicle, a vehicle motion state estimation apparatus, and a method for estimating a vehicle motion state capable of highly accurately estimating a state quantity of a bounce motion of a vehicle having a non-linear suspension characteristic. The vehicle motion state estimation apparatus in a vehicle, in which wheels and a vehicle body are coupled via a suspension, includes a bounce motion estimation unit that estimates and outputs a state quantity of a bounce motion of the vehicle based on traveling state information of the vehicle, and a correction value estimation unit that calculates a correction value to correct an output the bounce motion estimation unit. The correction value estimation unit calculates the correction value in consideration of a non-linear characteristic of the suspension.

摘要： An object of the present invention is to provide a vehicle motion state estimation device capable of estimating a vertical momentum of a vehicle with high accuracy from a wheel speed sensor signal during traveling such as acceleration or deceleration, turning, or the like where wheel slips in longitudinal and lateral directions occur. The present invention estimates and removes a variation component caused by a wheel slip from variation components of a wheel speed sensor signal to extract a variation component caused by a displacement of a suspension, and estimates a vertical momentum of a vehicle from the extracted variation component caused by the displacement of the suspension.

摘要： [Object]The present invention provides a suspension control apparatus that allows miniaturization of a solenoid valve.[Solution]When a controller is started up by a power source controller (a power source unit), the controller switches a control current from 0 ampere to a maximum current value I6 at the same time as the startup. After that, the control shifts to normal control. As a result, even if a hysteresis of a damping force characteristic is large relative to the control current, it is possible to promptly move a solenoid valve to a position to be used in the normal control.
