Abstract [en]

We have developed a teleoperated quad-bike to be able to test a rollover prevention system. It was equipped with onboard computers, power steering, throttle control, emergency power cutoff, an IMU module, pneumatic actuators, and mechanical retractable outriggers. An onboard computer system tracks the vehicle orientation and velocity in real time. When the vehicle is predicted to overturn the system activates functions to prevent a rollover. The functions are: - activation of retractable outriggers, - decrease the throttle for motor brake, - activation of rear wheel brakes. The system has no active steering. The system was field tested in winter conditions in mars 2010, and was able to prevent rollover situations sideways and backwards.
