摘要： The invention relates to a method for compensating for vertically oriented movements of a superstructure of a vehicle. The vehicle is provided with the superstructure and with an active undercarriage having a plurality of wheel which are in contact with the carriageway, wherein each wheel is connected via an actuator adjustable over its length at a wheel assigned to a suspension point with the superstructure. Vertically oriented movements of the superstructure are caused by an inclination of the carriageway and by unevennesses of the carriageway, a first change of the length of at least one actuator is carried out for frequencies in a first, lower frequency range, and a second change of the length of the at least one actuator is carried out for frequencies in a second, higher frequency range.

摘要： The vibration of a tire 10 of a running vehicle in the circumferential direction or the width direction is detected by a road surface condition estimating tire 10, provided with an acceleration sensor 11 and a signal processing unit 12. Data of a detected vibration waveform are divided into data of three domains, namely, a pre-leading domain, a contact patch domain, and a post-trailing domain, and then the vibration levels in the pre-leading domain and the contact patch domain, respectively, are extracted. At the same time, a vibration component in a low-frequency band and a vibration component in a high-frequency band are extracted respectively from the vibration levels in the respective domains, and respective vibration level ratios R, which are each a ratio thereof, are calculated. Then, on the vehicle body side, the condition of a road surface on which the vehicle is running is estimated, based on the calculated vibration level ratio R and a map 32M, stored in a storage means 32, showing a relationship between the vibration level ratio R of tire vibration and road surface conditions. Thus a road surface condition can be estimated with accuracy even when there are changes in temperature or vehicle speed.

摘要： In order to enhance the accuracy of estimation of a vehicle's sideslip angle, a sideslip angle estimation apparatus calculates an angle between the direction of centrifugal force acting on the vehicle body during cornering and the lateral direction of the vehicle body based on accelerations exerted on the vehicle body and acting in two different directions. A sideslip angle between the longitudinal direction of the vehicle body and the direction of travel of the vehicle is calculated based on the estimated angle.

摘要： A vehicle suspension spring system for a vehicle wheel station includes a hydraulic cylinder or strut having a piston which divides the cylinder volume into a main oil volume and an annular oil volume. The main oil volume communicates via a first oil passage with a first accumulator having a main gas volume. The annular oil volume communicates via a second oil passage with a second accumulator having an auxiliary gas volume. The oil in each accumulator is separated from the gas by a separator piston or diaphragm. A third oil passage with an isolating valve interconnects said first and second oil passages. Operation of the isolating valve is regulated by a controller. At least one sensor for sensing a parameter associated with vehicle attitude is connected to the controller. The controller is operable for switching the isolating valve between open and closed positions for altering spring stiffness of the strut in response to said sensed vehicle attitude parameter when the vehicle is in motion.

摘要： A road surface μ is updated with time on the basis of a present value (an estimation value E) of the road surface μ estimated to estimate the road surface μ. In this case, if there is acquired road-surface information in a vehicle travel direction that is detected by a road-side infrastructure, a specifying unit 11 specifies a road-surface friction coefficient based on the road-surface information. An estimating unit 12 sets the road surface μ (μinf) thus specified as an initial value, resets the present value of the road surface μ to the initial value, and then starts estimation of the road-surface friction coefficient based on this initial value. Accordingly, estimation precision of a road-surface friction coefficient is enhanced by using an initial value having high reliability in autonomous estimation of the road-surface friction coefficient.

摘要： The absolute roll angle of a vehicle body is estimated by blending two preliminary roll angle estimates based on their frequency so that the blended estimate continuously favors the more accurate of the preliminary roll angle estimates. A first preliminary roll angle estimate based on the measured roll rate is improved by initially compensating the roll rate signal for bias error using roll rate estimates inferred from other measured parameters. And a second preliminary roll angle estimate is determined based on the kinematic relationship among roll angle, lateral acceleration, yaw rate and vehicle speed. The blended estimate of roll angle utilizes a blending coefficient that varies with the frequency of the preliminary roll angle signals, and a blending factor used in the blending coefficient is set to different values depending whether the vehicle is in a steady-state or transient condition.
