A driver-assistance system (DAS) that combines an automatic road departure avoidance (RDA) system with the driver's steering input is presented. The system is based on a closed-loop driver decision estimator (DDE), which establishes the risk of road departure. If a road departure is likely to occur, the RDA system intervenes by correcting the steering angle. Robustness is guaranteed by an ...
A driving simulator experiment is presented investigating different road departure prevention (RDP) setups. To induce the risk of road departure, thirty test drivers were asked to avoid a pylon-confined area (obstacle) while keeping the vehicle within the road limits. The RDP system intervened by applying a haptic-feedback (i.e., haptic shared control) and/or correcting the steering angle (i.e., drive-by-wire...
This paper describes the deployment of a torque controlled force feedback steering device for human in the loop automotive simulations. The high bandwidth of the velocity controlled three phase brushless servomotor allows for a realistic representation of the virtual dynamics. The electromagnetic interference produced by the industrial servomotor and the controller made the elaboration stage challenging...
The development of a vision system to aid the autonomous navigation of an unmanned helicopter, primarily based on inertial sensors and GPS data, is presented. An unmanned helicopter has been equipped with appropriate sensors and a vision system fitted on a custom pan-tilt mechanism. Robust software, based on the Open Computer Vision Library (OpenCV), has been developed for handling images and video...
