Testing Process Control
No less than 12 emission dynamometer test benches form the centre of APL vehicle testing. With this well-equipped test environment, APL is able to map the complete testing process for its customers in-house: from simulation, components, engines and drivetrains to the complete vehicle on the chassis dynamometer — and also to testing performed on the road.
Vehicle Testing Challenges
The two main drivers of activities accompanying development are changes in the development of drive topologies and legal requirements.
This results in different testing and development tasks:
- ECU Calibration
- Calibration security
- Cold tests (-40°C)
- OBD tests and functionality
- Emission cycles from different countries
- Performing certification test in cooperation with TÜV (technical inspection service)
- Conformity Of Production (COP)
- Implementation of road measurements with portable emission measurement systems (PEMS)
Process
To enable the completion of testing activities in a chassis dynamometer environment, the following areas must be mastered:
Quality
- Correlation
— Accreditation
— Status of legislation
— Accreditation
— Status of legislation
Coordination of Testing Projects
- High level development objectives
— Control of the measurement process
— Evaluation of the measurements
— Prompt provision of reports
