A new strategy for on-line monitoring and competence assignment to driver and vehicle

This paper presents a new strategy for driver monitoring and competence assignment based mainly on standard sensory equipment. Within this a competence adapter assigns a competence level to each of both subsystems, driver and vehicle. In this manner short- and long-term reduced capabilities of the driver in regard to his driving task can be detected and may even compensated under some circumstances. In this concept the driver still maintains his responsibility as long he is conscious

Development of assistance systems for user groups with specific handicaps – a challenge for the ergonomic design process

The goal to develop an assistance system for handicapped users with several impairments was successfully achieved. The design process as a whole lifecycle with iterative processes was shortened by several reasons. But this newly applied design process with underlying design rules given from mechatronic and biomedical products results into a usable system for the targeted groups as well as for other potential users. The main components of the design process were an intensive task analysis and determining of user profiles and user requirements

Control concept for the simulation of a nonholonomic mobile robot with two steerable axes using MATLAB®

In this paper we discuss a control concept for a mobile robot. We demonstrate the robot type ASTro which is currently under development. This small- size robot has two steerable axes and will be used as a testbed system. We show the modelling for this type of robot and the realization with MATLAB®. The simulation shall enable the user to select a certain position within the mission area to command the robot to move to this point. The robot uses an event- driven, graph- based control scheme to determine whether the target is within the range it can reach directly or whether it is necessary to include an extra turn. The area borders are considered which may force the robot to perform a double bend to reach the target

The TFX-Strategy for the Automated Feature Extraction of Classifier Systems

This article describes a new strategy for feature generation. The strategy called TFX supports the user with the generation of features. For this it only needs a linguistic description of the interesting feature transformations. The resulting features can be described qualitatively by the kind of feature transformations and quantitatively by a suitable approximation
