    摘要: The invention provides first signals (w.sub.z, a.sub.L, a.sub.Q, a.sub.V1, a.sub.V2, a.sub.V3) representing the vehicle movements relative to an inertial reference system (K.sub.I) for use in a chassis regulation and/or control system in a vehicle. Based on the first signals, correction values (beta.sub.S, beta.sub.S ', beta.sub.S ", alpha.sub.S, alpha.sub.S ", psi.sub.S ', psi.sub.S ") for correction of the first signals are determined in such a way that vehicle movements relative to a road surface-fixed reference system (K.sub.S) are inferred from corrected first signals (S.sub.cor i). The invention has the advantage that the inertial sensor signals disturbed by road surface inclinations are projected into the road surface plane, obtaining signals which represent the vehicle movement relative to the road surface.

    摘要: The invention relates to a method of inputting the actual transmission ratio of a continuously variable transmission (CVT=continuously variable transmission) of a vehicle, especially a passenger motor vehicle. For this method, operating points of a shift characteristic field can be assumed which lie on a characteristic line of optimized consumption of a motor characteristic field of a motor of a vehicle. In this method, also operating points of the shift characteristic field can be assumed which lie on a characteristic line of optimized power of the motor characteristic field. The trace of the characteristic line of the shift characteristic field results from the particular selected characteristic line of the motor characteristic field. It is provided that operating points of the shift characteristic field can be assumed which lie on a dynamic characteristic line (c"') of the motor characteristic field. The dynamic characteristic line (c"') lies between the characteristic line (c') of the optimized consumption and the characteristic line (c") of the optimized power. The position of the dynamic characteristic line (c"') is dependent upon the magnitude of the rate of change of the power demand.

    摘要: The stiffness of the suspension is very much a function of the load in hydro-pneumatic vehicle suspensions. With high loads the vehicle suspension is stiff and with a light load it is relatively soft. In addition, the vehicle suspension of the wheel on the outside of the turn is stiffer than that of the wheel at the inside of the turn. The changes in the stiffness of the vehicle suspension are very disagreeable and can result in dangerous driving conditions. Equalization of the stiffness of the vehicle suspension is provided with the aid of a supplemental force. The supplemental force acts in the same direction as the load force of the vehicle chassis. The vehicle suspension is preferably suited for motor vehicles.

    摘要: An an ultrasonic drive element having a plurality of layers of piezoelectric material, arranged one on top of another to form a stack, between each of which is located a contacting layer for application of an operating voltage. Each of the contacting layers is subdivided into at least two electrically unconnected subregions, at least one of which has an electrode for making contact to the adjacent piezoelectric layers. By applying suitable alternating-current voltages to the electrode, the surface of the layer stack is excited into mechanical oscillations which contain a motion component parallel to the plane of said surface.

    摘要: A hydraulic control system for controlling at least two consumers (2, 4) includes a pump (6) with an adjustable delivery quantity. The consumers are each associated with an adjustable metering orifice (24, 38), having a power beyond connection (72) to which at least one power beyond consumer (74) is connectable. An inlet pressure governor unit (60) is connected downstream of the pump (6) and opens a connection to a tank (T). Its setting occurs as a function of a load pressure of the consumers (2, 4) or of the at least one power beyond consumer (74). The inlet pressure governor (60) is provided in the pressure fluid flow path between the pump (6) and one of the two consumers (2, 4), while the power beyond connection (72) branches off from the pressure fluid path between the pump (6) and the inlet pressure governor (60).
