The 100% test of the double-clutch transmissions is performed at the end of the line. The fully automated test cycle includes numerous measurements and function tests. •Fully-automated test procedure •Automated test- and final lifetime oil filling General •Automated test- and final lifetime oil filling of both oil circuits •Flexible test procedure programming via elementary steps •CAN-Bus communication with transmission STG •SQL-database for output data •Open interface to all measurement data •Printouts can be issued in PDF or HTML format and are thus platform-independent •Fully-automated test procedure Tests •Objective noise analysis •Gear adaptation mechanism •Clutch characteristic curve test (kiss point) •Sensor test (transmission internal sensors e.g. pressure, temperature, rotation speed) •Drag torque measurement •Differential test •E-Differential test •FFT analyses of the system pressure •Pump performance measurement of the internal transmission pumps •Simulation of the vehicle oil heat exchanger •Permanent inspection of oil purity according to DIN ISO 4606 •Shift time test •Synchronous test •Parking lock tests Equipment •NOVOTEST control software •Noise analysis system •NOVOTEST oil infrastructure for 2 oil circuits
