Precise measurement technology for all prototypes and test cars

In our vehicle equipment area, ATESTEO offers you a full scope of measurement technology for equipping your passenger and commercial vehicles with technical measuring equipment. Our service range extends from vehicle instrumentation to conducting and analysing the measurements and test runs. With precise measuring equipment, specific data from series or prototype vehicles is collected and made ready for the development of new vehicle concepts. Depending on the scope of the measurement technology installed in the vehicle, on the basis of the captured data records, simple components can be more closely characterised and complex relationships exhaustively assessed.

Highly-developed measuring equipment for the drivetrain

To determine the mechanical performance of rotating components, ATESTEO offers you highly specific telemetry systems that can be optimally adapted in their form and scope of function to the realities of innovative drive technologies. The optional central data collection enables synchronous processing of the measurement channels including the measured values read in through the vehicle bus (CAN). The functional reliability of more extensive installations is supported through fitting in an additional battery.

General reasons for vehicle testing and validation:

  • Data validation
  • Benchmarking
  • Performance testing of components
  • General vehicle testing
  • Calibration of the ECU (electronic control unit) or TCU (transmission control unit)
  • NVH (noise, vibration, harshness)
  • Degree of effectiveness
  • Component loading
  • Checking gear axis alignment (tumbling)
  • RLD (road load data)

We conduct torque measurements:

  • At side shafts and cardan shafts
  • On the engine flywheel
  • On the flexplate
  • On the transmission (gearbox) inlet (Manual transmission, Automated manual transmission, Automatic transmission, Double clutch transmission, Continuously variable transmission, hybrid)
  • Within the transmission
  • On the transmission outlet

We conduct temperature measurements:

Collection of component temperatures during operation is needed when components do not meet expectations for their function and durability (service life). The information about temperature is also needed when, for example, additional temperature information for further compensation purposes is required with torque sensors which have already been applied. Because of their versatility, mainly thermocouples are used for one-channel or multi-channel measurement of temperatures on clutches, friction pairings, or gears. In close cooperation with the customer, the individual thermocouples are often placed very precisely with the help of electro-erosion (electro-discharge machining) methods.
