    摘要: Provided is a way of using an estimator to determine a force (Fz), which acts from the outside on a steering gear of a steering device in a vehicle by way of a steering linkage, wherein a motor for generating a steering torque is assigned to the steering device. This is achieved by estimating the force (Fz) acting from the outside as a function of an effective motor torque (tor_RAeff), wherein the effective motor torque (tor_RAeff) is determined as a function of a motor torque and an efficiency, the efficiency being determined as a function of the estimated force (Fz).

    摘要: A method for determining a rack force for a steering apparatus of a vehicle, in which the rack force is determined as a function of a steering angle variable which characterizes an actual wheel steering angle or a set point of the wheel steering angle. In order to specify a method for determining a rack force, with which a target steering torque can be generated such that a comfortable steering feel is imparted to the driver and the steering apparatus nevertheless gives the driver feedback that is as realistic as possible regarding the motion state of the vehicle, the method comprises: determining a variable which characterizes a lateral force on a shaft of the steering apparatus, and determining the rack force as a function of the lateral force, wherein the determination of the rack force comprises a filtering by means of a signal processing element having a proportional-differential transfer function.

    摘要: A method for determining a steering rack force (FR) for a steering system of a vehicle, in which a first steering rack force (RFD) is ascertained as a function of at least one force that occurs in the steering system or at least one torque (tor_RA) that occurs in the steering system. So as to provide less strong feedback on the force conditions in the steering system for reasons of driving comfort, in particular when this is currently not required, it is proposed to ascertain a second steering rack force (RFC) as a function of at least one vehicle variable (v, ang_RA), which characterizes the state of movement of the vehicle, and to generate a resulting steering rack force (FR) based on the first steering rack force (RFD) and the second steering rack force (RFC).

    摘要: In sophisticated metallization systems, vertical contacts and metal lines may be formed on the basis of a dual inlaid strategy, wherein an edge rounding or corner rounding may be applied to the trench hard mask prior to forming the via openings on the basis of a self-aligned via trench concept. Consequently, self-aligned interconnect structures may be obtained, while at the same time providing superior fill conditions during the deposition of barrier materials and conductive fill materials.
