A method for lateral dynamic stabilization of a single-track motor vehicle during cornering; on the left side of the vehicle, the motor vehicle including at least one first nozzle, which is mounted at a first position located between the wheels, and through which a medium situated in a first container may escape into the surroundings of the motor vehicle, with a speed component pointed in the outer direction of the left side of the vehicle; and on the right side of the vehicle, the motor vehicle including at least one second nozzle, which is mounted at a second position located between the wheels, and through which a medium situated in a second container may escape into the surroundings of the motor vehicle, with a speed component pointed in the outer direction of the right side of the vehicle; &#x2014;where a presence of an unstable driving condition in a lateral direction of the vehicle is detected, and&#x2014;as a function of this, with the aid of an actuator system, on only one side of the vehicle, the medium is caused to escape through the at least one nozzle mounted on this side of the vehicle, in order to stabilize the motor vehicle.

A method/control unit for recognizing critical driving situations of a two-wheeled motor vehicle (MV), including: ascertaining an instantaneous slip angle (ISA) and differential slip angle (DSA) of the front/rear wheels; ascertaining an instantaneous roll angle (IRA); comparing the ascertained SAs and DSAs to predetermined values (PV) of maximum allowable slip angles (MASA) or DSAs; comparing the IRA to PVs of a maximum allowable roll angle (MARA); and generating a criticality signal when one of the ISAs is greater than the PV of the MASA, at least one of the instantaneous DSAs is greater than the PV of the maximum allowable DSA, and the IRA is greater than the PV of the MARA. Critical driving situations are recognized with the method, and measures for stabilizing the two-wheeled MV or other safety-enhancing measures may be performed. Special driving situations (driving over low-&#x3bc; patches or braking while negotiating a curve) may be considered.

A method for reducing the steering torque of a two-wheeler when negotiating curves. For the case that the front wheel is braked while negotiating a curve, the damping in an adaptive steering stamper is increased as a function of at least one state variable characterizing the negotiation of a curve.

A method of detecting a transverse-dynamically hazardous operating state of a vehicle, where a variable describing the rotational speed of at least one wheel on an axle is determined; a first variable describing the vehicle transverse dynamics is determined from at least the one variable describing the wheel rotational speed; at least one second variable describing the vehicle transverse dynamics is determined from sensor signals; and the transverse-dynamically hazardous state is detected at least as a function of the first variable describing the vehicle transverse dynamics and the second variable describing the vehicle transverse dynamics. The transverse-dynamically hazardous operating state is defined by this wheel on the axle lifting off the roadway or by an imminent danger of this wheel lifting off the roadway; and the transverse-dynamically hazardous operating state is detected as a function of the engine torque (Mmot) acting upon this axle.

An electric drive for an electric or hybrid vehicle has an electric motor, with which a vehicle wheel is drivable, for instance via an articulated shaft. The the electric drive is embodied additionally with a mechanically actuatable wheel brake, which is actuatable by the electric motor selectively for driving the vehicle wheel via a shiftable distributor gear. The invention has the advantage that the electric motor provided for driving the vehicle wheel is simultaneously used for actuating the wheel brake () as well.

A system for controlling and/or regulating the driving response of a motor vehicle having at least two wheels includes at least one sensor device, which detects a wheel speed of at least two wheels, and further includes a data processing device, which determines at least one motion relationship of at least two wheels relative to one another according to the wheel speeds detected. As described, the data processing device establishes at least one cornering motion variable of the vehicle according to the at least one motion relationship determined. A corresponding method is also described.

A method for establishing the angular position of the vehicle with the aid of at least one roll or rotation rate sensor, and which is checked in the course of a plausibility inspection, to check whether the integrated rotation rate signal is able to reproduce the actual angular position of the vehicle at all or whether it lies outside the angular range which may be considered for the actual angular position of the vehicle on the basis of the driving situation. In particular, the method for establishing the angular position of the vehicle relative to at least one rotational axis, particularly its longitudinal axis and/or its transverse axis, in which the rotation rate of the vehicle about the rotational axis is detected using at least one rotation rate sensor and the angular position, particularly the roll angle about the longitudinal axis of the vehicle and/or the pitch angle about the transverse axis of the vehicle, is established by integration of the detected rotation rate, with the offset error of the rotation rate sensor being taken into consideration, in addition to the rotation rate, the transverse acceleration (that is, the acceleration of the vehicle transverse to the rotational axis) is detected, and is then checked, with reference to the dependence of the actual angular position of the vehicle on the transverse acceleration AQ, to determine whether the established angular position may correspond to the actual angular position of the vehicle.

A calibration of a system which operates in dependence on a sensor in a motor vehicle includes testing, with the use of sensors available in a motor vehicle or with the use of data representative of selected conditions or processes or signals of control devices available in the motor vehicle, whether it can be ascertained that nobody is located in a motor vehicle which can influence variables to be determined by a sensor of a system to be calibrated, and performing the calibration when the testing confirms that it can be ascertained that nobody is located in the motor vehicle which can influence variables to be detected by the sensor of the system to be calibrated.

The invention relates to a vehicle hydraulic brake system with electrohydraulic brake boosting by a piston pump. In order to reduce pressure pulsations on an intake side of the multi-piston pump, the brake system embodies a multi-piston pump, for example, as a six-piston pump with stepped pistons that are driven with an alternating phase shift of 30&deg; and 90&deg; in relation to one another. The phase shift of the drive of the stepped pistons is selected so that the intake volume flows have a uniform phase shift, by which the total intake volume flow of the multi-piston pump has a reduced amplitude of the pressure pulsation, which reduces the repercussions on a master cylinder.

Method and device for triggering a pressure medium delivery arrangement, in particular a pump, of a brake system. The triggering signal for the triggering or regulation of the pump is formed dependent upon at least one pressure differential. In one embodiment, at least one of three different pressure differentials is used for forming the triggering signal. For this purpose, the brake circuit pressure, the master brake cylinder path, and the master brake cylinder pressure are determined and used in the formation of target values. The pump or the pump motor is then regulated using the particular pressure differentials and/or is activated through a pilot control value.
