IMU and GPS, Core Parts of the Driverless Car For the first time ever, Formula Student Germany introduced a driverless category, where race cars had to be adapted to drive without any human intervention. AMZ decided to take the challenge, and prepared “flüela”, their car used for competition from 2015, to be driverless. For the AMZ team, when designing a driverless vehicle, the IMU and the GPS are a core part of the sensor suite.

The Ellipse2-N fuses inertial data and position information for a continuous trajectory even in case of GNSS outage. Used in Very Tough Conditions According to the AMZ team, it was a tough testing season with very hot days, extremely rainy days, a lot of vibrations, mounting, unmounting, plugging, unplugging. The sensor never failed. Every SBG inertial sensor is calibrated in dynamics and temperature (-40° to 80°C) for a constant behavior in every condition. AMZ Racing Success The team managed to be: first in skidpad (ability to turn at steady state as fast as possible) first in trackdrive (race in an unknown track marked with cones), second in acceleration (measures the ability of the car to accelerate fast). The overall event includes static disciplines in which the team also obtained good results: first in engineering design and cost, second in autonomous design and third in business plan presentation. AMZ reached the podium in each of the eight disciplines, and won five of them. Photo credit: Christian Kreutzmann We were amazed by the quality of the gyroscopes.
