Considering Issues of Stability and the Human-Machine Interface

Teleoperated vehicles are gaining importance during the transition to fully automated vehicles since, at the current state of development, automated vehicles are not capable of operating in all conditions and environments. Despite the high potential of the concept of teleoperated vehicles, there are still challenges that need to be dealt with. As the driver is not physically present in the vehicle when teleoperating a vehicle, they lack information about the vehicle motion. Further communication delays limit the speed of stable vehicle handling.

To increase the driver’s perception and the manoeuvrability of the teleoperated vehicle, a tuneable torque emulation concept is introduced, studied, and tested in a simulation environment, in a simulator environment and in real application.

Further, stability analysis is applied to better understand the limits of speed for safe vehicle handling and the steer-by-wire system or in this case, steer-over-the-air system, is adapted to possibly extend these limits.
