Abstract: In a method, a steeringwheel torque for the steering wheel of a motor vehicle is determined. In this context, a steering angle for steered wheels is predefined by the driver by means of the steering wheel. A steering torque which represents the forces on the vehicle axle acts on the steering wheel. A desired manual torque (M_soll) is determined here using at least one axle model. The desired manual torque is then superimposed on the actual steeringwheel torque (M_ist).

Abstract: The invention relates to a method that permits the determination of a steering-wheel torque for the steering wheel of a motor vehicle. A steering angle is predefined by the driver for the steered wheels by means of the steering wheel. A steering torque that represents the forces on the vehicle axis acts on the steering wheel. According to the invention, a manual torque (M_desired) is determined using at least one axle model. The manual torque is then superimposed on the steering-wheel torque M_actual).

Abstract: The invention relates to a method for determining a steering torque which acts when a steering wheel is activated in motor vehicles. In a motor vehicle, the steering torque which acts when a steering wheel is activated is determined. The motor vehicle here is in particular a motor vehicle whose steered wheels are driven. In this context, according to one method according to the invention the interference torque component (M_stör), based on interference influences, of the steering torque is determined. A steering torque (M_soll) with reduced interference force, in particular free of the influence of an interference force, is then generated at the steering wheel by means of a torque generator (108).

Abstract: The device according to the invention relates to a device for making available parameters which are taken into account during the regulation and/or control of a parameter which describes and/or influences the movement of a vehicle. The parameters which are made available are vehicle movement parameters which describe the movement of the vehicle and/or underlying surface parameters which describe the quality and/or the course of the underlying surface. The device according to the invention contains sensing means with which first vehicle movement parameters are sensed, and computing means with which second vehicle movement parameters and/or underlying surface parameters are determined at least as a function of the first vehicle movement parameters. The sensing means and the computing means are spatially combined to form one physical unit.

Abstract: A method and apparatus for braking a vehicle having a vehicle brake system with a brake control device, and an engine whose torque is transmitted via a transmission to driven wheels. When there is a malfunction of the braking system and a demand for a braking operation, the transmission ratio is increased by a transmission control unit, which activates the transmission, to produce increased braking torque at the driven wheels.

Abstract: The invention relates to a method for detecting parameters characterizing the driving behavior of a vehicle, according to which at least one vehicle speed parameter, which represents at least one parameter (?y) describing the lateral velocity, and/or a roadway parameter describing the quality and/or the course of the roadway is/are detected at least according to one parameter (ax) describing the longitudinal acceleration of the vehicle, a parameter (ay) describing the lateral acceleration of the vehicle, a parameter ({dot over (?)}) describing the yaw rate of the vehicle, a parameter (?, ?Rad,i) characterizing the steering lock of the steered wheels, and parameters (?Rad,i) describing the rotation speeds of the vehicle wheels by means of an estimation method. A parameter (vx) describing ongitudinal velocity of the vehicle is detected as an additional vehicle speed parameter.

Abstract: The invention relates to a method for operation of a steering device (10) and to a steering device (10) for a vehicle, having a steering actuator (12) for setting the steering angle on the steered vehicle wheels (11) and having a steering handle (14) which is mechanically decoupled from the steering actuator (12) during disturbance-free operation. A nominal steering angle is determined on the basis of the operation of the steering handle (14) and is set on the steered vehicle wheels (11). At least during disturbance-free operation, at least one variable which describes the transverse dynamics of the vehicle is taken into account in the determination of the nominal steering angle. A disturbance influence which acts laterally with respect to the direction of travel is also determined from this variable which describes the transverse dynamics of the vehicle or from an assessment variable which is derived from it.

Abstract: A braking-force control system and method is provided for a road vehicle having an electrically controllable four-circuit brake system. The braking forces generated by the individual wheel brakes can be adjusted in a wheel-specific way. Adjustment devices on a chassis vary the normal forces acting on the vehicle wheels, with at least one normal-force adjustment device being provided per vehicle wheel. The adjustment devices are configured so that, for the most part, the weight of the vehicle can be supported on one of the front wheels and on the rear wheel of the vehicle which is arranged diagonally opposite the latter. The braking force generated by a front-wheel brake and the rear-wheel brake which lies opposite the latter viewed along the diagonal of the vehicle, corresponds overall to the vehicle weight multiplied by a maximum coefficient of friction which is effective between the carriageway and the braked wheels.
