摘要:
An automatic vehicle tire pressure measurement/adjustment system for measuring and adjusting the tire pressure of a vehicle. The system includes an automatic handling unit having a pressure attachment positionable into a tire pressure measurement/adjustment position onto a valve of a tire, a tire pressure measurement device connectable to the pressure attachment for measuring the existing tire pressure, a determination device for determining a nominal tire pressure based on at least one vehicle-specific parameter, a first communication device located in the vehicle and connectable to the determination device for input of the at least one vehicle-specific parameter into the determination device, and a tire pressure adjustment device connectable to the pressure attachment and connectable to the determination device for transmitting the nominal tire pressure to establish a transmitted nominal tire pressure.
摘要:
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 (24) as well.

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° and 90° 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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
A method and a device for regulated actuation of a proportionally operated solenoid valve are described. The described method and the described device are distinguished by the fact that the actuation of the solenoid valve takes place under consideration for the regulating processes which were necessary prior to such time in order to operate the solenoid valve according to specifications.
摘要:
Vehicle speed is measured during slip-free travel of the wheels and compared with the wheel speeds to determine correction values which correct for different wheel diameters. The correction values are used to continuously correct the wheel speeds.

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.
摘要:
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.
