4WD-Testbench for Drivetrain and Hybrid-Vehicle Optimization
Testbenches for the automotive industry of today have to fulfill more and higher requests in comparison to the past. The testruns become more complex and they have to simulate the real driving conditions as exactly and reproducably as possible.
For measuring real CO2- and emissions-values , fuel consumptions and/or electricity consumption values the European Union developed the new test procedure WLTP (world wide light duty transient procedure) which is fixed in the legislative since September of 2018 for new passenger car homologation. It replaces the former NEDC-cycle (new European driving cycle) to be the new basis for the official type approval of new passenger cars.
ElringKlinger Motortechnik introduced a new and modern 4WD-drivetrain testbench in order to fulfill the new demands of the clients respecting all the restrictions of the WLTP-legislation and of the new real driving emissions legislation (RDE). This testbench offers a significant higher power potential and higher flexibility for all sorts of test runs.
Because of the rising innovation pressure time slots to realize a full development process until readiness for series production have been becoming significantly smaller. The rising complexity of drivetrain components including their electronic management and the cumulationg interaction of various ECU´s for engine, gearbox and hybrid drive – may be in combination with an intelligent driver assistant system – make it necessary to have an early validation of the total drivetrain even when the first prototype vehicle is not available and not ready yet.
Multi Configuration Testbench for a Wide Spectrum of Investigations
On the new 4WD-testbench test with high accuracy, dynamic, flexibility for all sorts of drivetrains can be performed. The testbench covers combustion engines, hybrid drives (combustion engines combined with electric motors in a serial or parallel configuration) range extender configurations, fuel cell drives as well as pure electric drives.
Beside the single component testing of the combustion engines, gearboxes, electric motors and batteries especially control strategies for the interaction of the various hybrid components can be tested, optimized and evaluated. Hence, for the development of different drivetrain concepts only one testbench installation is needed.
The feature-catalogue of the testbench includes:
