Road to Rig is truly possible at last: The integrated development methodology combined with the innovative test bed for the comprehensive validation of alternative drivetrain systems

摘要

A revolutionary new Drive System Test Rig (ASP) enables the validation of both entire alternative powertrains and also complete vehicles. The complex dependencies between the electrified powertrain and the entire vehicle are replicated with regard to mechanical and electrical loads, stresses and environmental temperatures under real conditions for test cases ranging from simulation to component testing to trials in the vehicle. The centrepiece of the Drive System Test Rig for both conventional and also for alternative drive systems consists of the new test rig concept R2R (Road to Rig) which stresses the test object in the very same way as on the real road, with minimum set-up time and without parameterisation of controllers. Furthermore, the assistance systems of the vehicle are also active during the trials on the test rig. The shown results of the comparative measurements between road and test rig prove that the claim "Road to Rig" is met, even in extreme situations like icy patch and ABS braking.
