AIRBAG-MISUSE

When should an airbag NOT deploy? In a crash, it saves lives and protects against injuries; in the case of minor impacts, such as a football, deploying the airbag would be counterproductive. We ensure the development status of a vehicle's airbag system is validated and conduct various misuse tests in both driving and stationary tests.

  • Commissioning of the measuring technology for data recording during the test
  • Coordination and supervision of tests on the test sites
  • Measurement data evaluation
  • Pendulum tests for impact simulation on our own test bench

ENGINE COOLING AND COMPONENT TEMPERATURES

To assess engine cooling and critical component temperatures under extreme loads, Volke conducts extensive measurements in its own vehicle climate chamber and with its own roller dynamometer. For example, temperature measuring points are placed in the engine compartment and in the exhaust system area, cooling water flow rates are determined, and vehicle loads are tested in road tests with the towing dynamometer and on the roller dynamometer in the climate chamber. Special measurements are also possible: For example, energy balance studies during the cold start phase are possible to assess heat input. Based on these results, suitable additional measures such as auxiliary heaters or increased generator loads can be recommended to contribute to faster interior heating.

    VEHICLE AIR CONDITIONING

    Today, vehicle air conditioning is a crucial comfort criterion. With extensive measurement technology for temperature, pressure, voltage, current, flow, CAN bus signals, and air volumes, Volke handles all tasks related to vehicle ventilation and air conditioning in its in-house vehicle climate chamber. This includes the examination of defrosting, dehumidification, cooling, and heating systems, as well as air volume measurements. Volke also offers support with vent optimization and air duct design. Furthermore, Volke conducts competitive analyses and series production monitoring in this area.

      BRAKE TESTING

      We conduct brake tests on test tracks, verifying the performance of the braking system and compliance with legal requirements.
      We also offer special measurements such as pressure series, deceleration series, consecutive stops, and temperature measurements.

        • Testing focuses: wheel brakes, foot pedals, wheels and tires, wheel covers
        • Approval tests for the entire braking system according to FMVSS 135 and ECE-R13H
        • Vehicle endurance tests to ensure wear behavior and brake comfort
        • Determination of braking distances (tyre wet and dry braking)
        • Testing of tire pressure monitoring systems
        • Approval tests of wheel covers also under environmental influences and in road tests

        WHEELS, TIRES and WHEEL COVERS TESTING

        Component testing: wheels and wheel covers

          • Testing of components in driving and test bench tests as well as under environmental influences
          • Dynamic testing of wheel bolt tightness in road tests

          Tire test

            • Determination of braking distances on dry and wet roads
            • Testing of tire pressure monitoring systems
