Emission Optimisation on the Chassis Dyno or the Road
Basic Data Input — On-Board Diagnostics (OBD) — Emissions
Most of the data input for emission-relevant functions and on-board diagnostics happens on our state-of-the-art chassis dynamometer test benches. In addition to verifying compliance with legal regulations for the respective countries, statutory passenger car type testing in Europe requires emission measurements under real driving conditions. APL offers a truly holistic approach for this kind of testing: from individual route selection, through adaptation and comparison of measurement technologies, to data evaluation compliant with legal requirements. PEMS (Portable Emissions Measurement System) measurement technologies are also utilised during the development phase to ensure reliable data acquisition.
Due to the increasing degree of electrification of vehicle drive trains and the digitisation of vehicles, chassis dyno test-bench-ready prototypes are first available at a relatively late stage. In order to be able to carry out emission and consumption optimisations as early as possible in the development process, the APL drive train testing facility offers highly sophisticated test benches with corresponding measurement technology and technical equipment. In this environment, virtual components can be successively replaced by new hardware, thus enabling the entire, complex system to be developed to full production readiness.
Certification and Conformity of Production
Post-CoP (Conformity of Production) testing serves as both quality assurance and to determine production tolerances in assembly processes. Conformity of production must be demonstrated for all configurations and is intended to ensure that every produced vehicle conforms to the type approval.
