摘要： The invention relates to a method for controlling retarder operation of a motor vehicle (100, 110), comprising the steps of: - continuously detecting temperatures (T) of the retarder's fluid (graph a); - continuously determining a change in the detected temperature; and - automatically disconnecting the operation of the retarder when said detected temperature exceeds a predetermined temperature. Said predetermined temperature (graph b) is determined continuously on the basis of the magnitude of the change per unit time. The invention relates also to a computer programme product comprising programme code for a computer for implementing a method according to the invention. The invention relates also to a device and a motor vehicle equipped with the device.

摘要： The invention relates to a brake system, in particular for a motor vehicle, comprising an external working-medium circuit and a hydrodynamic retarder that includes a bladed rotor and a bladed stator, which together form a toroidal working chamber, which can be filled with working medium from the external working-medium circuit through an inlet, wherein said working medium is conducted back into the external working-medium circuit through an outlet. The brake system further comprises a storage chamber for accommodating working medium that is currently not located in the working chamber or circulating in the external working-medium circuit and comprises a pressurization system for applying a control pressure to the working medium contained in the storage chamber so that more or less working medium is forced into the working chamber in order to set a desired braking torque. The invention is characterized by a throttle valve connected downstream of the outlet and including a movable or deformable valve body in order to vary the flow cross-section for working medium from the working chamber, wherein the valve body is exposed to working-medium pressure from the working chamber of the hydrodynamic retarder in the opening direction of the throttle valve and to the control pressure or a pressure dependent on the control pressure in the closing direction.

摘要： The invention relates to a method for operating a hydraulic or pneumatic system. The system comprises at least one pressure accumulator. The system is provided with at least one valve unit and a sensor for the at least indirect detection of the position of the valve unit and/or at least one sensor for the detection of a value that is at least indirectly related to the pressure on the side of the valve unit facing away from the pressure accumulator. At least one value is detected with one of the sensors when using the method. According to the invention, the detected value or values is or are compared to reference values. On the basis of an agreement or a difference between the value(s) and the reference values, an error function of the system and/or the pressure in the region of the system present on the side facing away from the sensor for detecting a value which relates at least indirectly to the pressure on the side of the valve unit facing away from the pressure accumulator, are determined.

摘要： The invention relates to a method for matching an actual characteristic curve or characteristic diagram, which characterize the operating mode of a hydrodynamic component, to a set characteristic curve or characteristic diagram, which characterize the operating mode of a hydrodynamic component, during the final test thereof. The inventive method for matching an actual characteristic curve or characteristic diagram, which characterize the operating mode of a hydrodynamic component, to a set characteristic curve or characteristic diagram, which characterize the operating mode of a hydrodynamic component, during the final test thereof is characterized by the following features: a set characteristic curve or a set characteristic diagram of the hydrodynamic component, which describe the desired operating mode, is stored in a writable/readable memory unit assigned to the hydrodynamic component, a set manipulated variable being assigned to each operating point; the current actual characteristic curve is determined from the operating parameters that characterize the individual operating states, and for each operating point, are compared with the given set characteristic curve or with the set characteristic diagram, a correction of the set manipulated variable being carried out for the respective operating point in the event of a deviation beyond a preset range of tolerances, and; in the event a deviation does not occur, the current set value is set as the new set value and read into the memory unit as a set manipulated variable.

摘要： The invention relates to a method for optimising the operation of a hydrodynamic component integrated into a drive train of a vehicle, using a regulating device associated with said component. According to said method, a nominal characteristic line or a nominal characteristic diagram is stored in a memory unit for a hydrodynamic component; an actual value (N ist-n; M ist-n) of at least one variable at least indirectly characterising an operating point (N ist-ni; M ist-ni) is determined for each transmission process; and the actual value (N ist-n; M ist-n) is compared with the nominal value from the nominal characteristic diagram. If the actual value deviates from the nominal value, the regulating variable for the operating point in question is modified and stored as a new nominal regulating variable for said operating point (N ist-ni; M ist-ni).

摘要： The invention relates to a method for controlling and/or regulating the vehicle speed of a vehicle which is provided with a retarder. Overshoots in vehicle speed regarding a stored nominal speed are reduced or avoided when the retarded is switched on. The retarded is switched on before the stored nominal speed is reached so that the braking effect is already built up and the acceleration of the vehicle can be reduced or minimized before the stored nominal speed is reached.
