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)
To enable the comple­ti­on of test­ing acti­vi­ties in a chas­sis dyna­mo­me­ter envi­ron­ment, the follo­wing areas must be mastered:


- Corre­la­ti­on
— 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


- Vehic­le planning
— Effi­ci­ent use of capa­ci­ties in compli­ance with specifications
— Reporting
— Flexi­ble imple­men­ta­ti­on of short-term specifications
Areas of Respon­si­bi­li­ty for Drive­train Testing
Quali­ty / Markets
  • Accre­di­ted test faci­li­ty accor­ding to DIN ISO 17025
  • Vali­da­ti­on of measu­re­ment data by TÜV (tech­ni­cal inspec­tion service provider)
  • Compli­ance with requi­re­ments for certi­fi­ca­ti­on and COP
  • Current status of legis­la­ti­on for various markets
  • Proof of cali­bra­ti­on accor­ding to speci­fic country’s specifications
  • Inter­nal corre­la­ti­on and parti­ci­pa­ti­on in inter­la­bo­ra­to­ry comparisons
  • Vehic­le conversions
  • Trans­pa­rent, flexi­ble planning
  • Prepa­ra­ti­on of data in indi­vi­du­al custo­mer format
  • Proto­ty­pe and data protection
  • IT Secu­ri­ty
  • Secu­re data connec­tion → prompt trans­mis­si­on of analy­sis and raw data
  • Centra­li­sed commu­ni­ca­ti­on channels
