摘要： The disclosure relates to a method for determining a starting condition for cleaning a brake disk. A first step (S1) of this method determines that an amount of rust on the brake disk exceeds a defined threshold. Additionally, an energy quantity being necessary for removing the amount of rust from the brake disk is determined (S2). In a further step (S3), a distribution of brake energy over a current drive is estimated by using at least one parameter describing historic driving behavior and at least one parameter characterizing the current drive cycle. Subsequently, a starting speed and a starting brake force request is derived (S4). Additionally, a method for cleaning a brake disk is presented which comprises the determination of a starting condition for cleaning the brake disk by the method mentioned before. Moreover, a data processing device comprising means for carrying out said methods is explained.

摘要： A method for operating a brake system of an at least double-tracked motor vehicle comprises two breakable wheels, which are arranged at opposite ends of an axle, and a rollover protection system which can cause braking of the wheels in order to prevent a rollover situation. Automatic braking of that wheel of the axle which is loaded more greatly when cornering is brought about by way of the rollover protection system. Subsequently, a smaller steering lock angle or a lower lateral acceleration than in the case of the cornering which took place immediately previously, or a straightahead driving phase which immediately follows the cornering is detected. Thereupon, automatic braking of the two wheels on the axle is brought about.

摘要： A driver assistance system for automated longitudinal guidance of a motor vehicle includes a sensor system configured to identify an upcoming traffic scene, including locating road users situated ahead of the motor vehicle; and a control unit. The control unit is configured to carry out an automated longitudinal guidance of the motor vehicle depending on the upcoming traffic scene such that, in response to detecting that the upcoming traffic scene is a following-travel standstill situation, the motor vehicle is braked to a standstill at a target stopping distance from a road user situated ahead and identified as a target object. The control unit is also configured to detect a manual request to reduce the predefined target stopping distance. The control unit is further configured to reduce the target stopping distance to a reduced target stopping distance on the basis of the request.

摘要： In the case of a method for operating a brake system of an at least double-tracked motor vehicle (10) which comprises 2 breakable wheels (12L, 12R), which are arranged at opposite ends of an axle (14V), and a rollover protection system, which can cause braking of the wheels (12L, 12R) in order to prevent a rollover situation, automatic braking of that wheel of the axle (14V), which is loaded more greatly when cornering is brought about by way of the rollover protection system. Subsequently, a counter-steering movement is detected by way of a predefined steering angle change being exceeded in a predefined time period in the direction counter to the cornering direction, and, thereupon, a brake force is caused to be built up at the opposite wheel, which is loaded less greatly by way of the rollover protection system.

摘要： The invention relates to a method for controlling an aircraft taxi system, comprising the steps of: generating a traction command (Com) to control an electric motor of a wheel drive actuator; detecting whether or not an external brake command, intended to control braking of the wheel via the brake, is generated; if an external braking command is generated, producing a predetermined minimum command (Cmp) to control the electric motor so that the drive actuator applies a strictly positive predetermined minimum motor torque to the wheel during braking; detecting whether a speed of the aircraft becomes zero and, if so, inhibiting the predetermined minimum command (Cmp) so that the drive actuator applies zero torque to the wheel.

摘要： A hydrodynamic retarder having a rotor and a stator or a rotor and an oppositely running rotor, which together form a toroidal working chamber to filled with working medium, in order to transmit a torque by means of a hydrodynamic working chamber working medium circuit. An external working medium circuit has a heat exchanger that discharges heat from the working medium. The external working medium circuit is connected by a working medium inlet and a working medium outlet to the working chamber. The working medium inlet and outlet open to the working chamber at a torus outer diameter of the working chamber. A working medium feed line opens into the external working medium circuit. A core ring filling line is connected in working-medium-conducting fashion to the working chamber. The core ring filling line opens into a core ring of the working chamber radially within the torus outer diameter.
