Problems solved by technology

This often leads to the fact that the theoretically transmissible torque cannot be fully utilized in practice, and thus either the hydrodynamic components are initially dimensioned correspondingly larger, or compensating for it by retroactive structural compensatory measures.

Embodiment Construction

[0020] Taking the optimization of the braking power supply in the motor vehicle 1 as an example, figure 1 The basic sequence of the method according to the invention is shown in a simplified schematic diagram, the motor vehicle comprising a drive train 2 with a drive machine 3 which is at least indirectly connected to the wheels 4 to be driven. A hydrodynamic component, in the illustrated case a hydrodynamic braking device 5 in the form of a hydrodynamic retarder, is arranged in the drive train 2 . exist figure 2 The functional interrelationships of the drive train 2 are shown schematically and greatly simplified in . The hydrodynamic component in the form of a speed reducer 5 comprises a primary wheel P acting as a rotor wheel R and a secondary wheel T acting as a stator wheel S. Here, the secondary impeller T is stationary. A working medium supply system 6 with at least one adjusting device 10 is assigned to the gear unit 5 . Because the braking power of the hydrodynami...

Abstract

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).

Description

technical field [0001] The invention relates to a method for optimizing the running behavior of a hydrodynamic component integrated in a motor vehicle drive train, in particular for optimizing a transmissible torque or an available braking torque, which is specifically claimed in the claims Features of the preamble to 1. The invention also relates to a method for optimizing the utilization of the available braking torque, which is characterized in particular by the preamble of claim 2 . Background technique [0002] In addition to hydraulic or mechanical systems, hydrodynamic retarders are often used as braking devices in motor vehicles. The gear unit can be integrated anywhere in the drive train as an additional brake or as a main brake. In this case, it is conceivable to install the reduction gear before, in or after the gearbox when transmitting power from the drive machine to the wheels. At this time, the manufacturer assigns a specific characteristic curve family to ...
