Intelligent vehicles operating in different levels of automation require the driver to fully or partially conduct the dynamic driving task (DDT) and to conduct fallback performance of the DDT, during a trip. Such vehicles create the need for novel human-machine interfaces (HMIs) designed to conduct high-level vehicle control tasks. Multimodal interfaces (MMIs) have advantages such as improved recognition,...
In this paper we investigate the design of a lane-tracking driver-assist system and, in particular, its interaction with the well-known two-point visual perception driver model. We present two different driver-vehicle interconnections and two different control designs that assist the driver in the lane-tracking task; the first design is based on linear multivariable output regulator theory, and the...
To solve the problem that traffic safety risks is difficult to identify and compare quantitatively for the new road or accident black spots, the virtual simulation tests (VST) system is put forward combined the numerical simulation. The driver module on vehicle speed control, the vehicle dynamic network solution module, traffic environment 3D model, traffic safety management and control module, human-vehicle-road...
When driving at night, it is difficult to detect obstacles such as pedestrian and wild animals on the opposite lane which is out of sight. Adaptive front lighting system (AFS) can be used to avoid accidents with obstacles that are difficult to detect with a conventional lighting system. The basic concept of AFS is to collect the information such as vehicle speed, yaw rate, steering angle, suspension...
The work described in this paper is part of a larger research program named Partage whose goal is to appropriately share lateral control between the driver and an electronic copilot or assistance. The present study is looking for a cybernetic model of a driver steering road vehicle, which makes the sensorimotor dynamics explicit. The proposed model takes into account both visual and kinesthetic perception,...
This paper describes a G3 transition curve based on quartic Bezier spiral to be used in the design of horizontal geometry of routes. The curve that joins two straight lines will be the composition of spiral-circular arc-spiral forms. It is an alternative curve to traditionally used transition spiral; clothoid. A family of quartic Bezier spiral is defined from analyzing the monotone curvature conditions,...
