Driving robots in advanced vehicle test system powered by ELMO servo drives

The Background

The company ABD produces driverless robot systems for testing the vehicle dynamics and also develops Guided Soft Target Vehicle (GSTV) used to simulate a collision and collect the data for automotive manufacturers in active safety markets.

The Challenge

Typical or traditional vehicle dynamics testing requires a test driver to put a step or sinusoidal inputs into the steering. The more repeatable to make those inputs to get the same every time, the higher possibility to collect better quality data about how the car handles. Although using a human test driver is undoubtedly still an important part of testing for any new automotive model, even the most experienced driver will be subject to fatigue and physical stress, which can have a detrimental affect on repeatability.

Addressing this need, the company needs to design its driverless steering robot & pedal robots for the brake and clutch; a further challenge is to develop a system by which a vehicle could steer itself through a defined path using GPS. All of these require to be very precisely controlled and robust.

Motion Control Products / Elmo was put to the test, to supply a servo drive that:

  • Provides smooth and robust motion (car model: Volvo V60)
  • Sustains high power density and high levels of current
  • Tailored to the limited space available for servo drives in the vehicle
  • Provides the required precision
