چکیده

Through the use of a virtual tractor-trailer link model, vehicle following capabilities have been implemented without the need of communications links between the two vehicles or the installation of special road infrastructure. The principle is based on the modeling of an off-hooked trailer system as a software link between the lead and led vehicles. The leader vehicle is modeled as the tractor (towing vehicle) whilst the follower vehicle as the trailer (towed vehicle). The conventional approach is for the led vehicle to follow a focus point in the leader vehicle, in the approach presented in this paper, following the leader vehicle is done by following the estimated trajectory of the virtual trailer, which is predicted from observations of the lead vehicle behavior. The system response of this configuration is much smoother. A series of simulations and experiments conducted has shown the validity of the proposed approach. Index Terms – Vehicle following, Virtual trailer system.

Bayesian Estimation of Follower and Leader Vehicle Poses with a Virtual Trailer Link Model

Autonomous Vehicle Following can be achieved if the poses of both the follower and leader vehicles are continuously estimated. This can be achieved by using a Bayesian estimation technique together with a virtual trailer link model. The advantage of such a model is that the follower vehicle will trail a virtual trailer, modeled as an attachment to the leader vehicle, instead of the leader vehic...

Trajectory Tracking Weeled Mobile Robot Using Backstepping Method with Connection off Axle Trailer

The connection of the tractor to the inactive trailer or motor vehicle causes a motion control problem when turning in the screw, forward or backward movements and high speeds. This is due to the inactive trailer being controlled by the tracking using a physical link that is not affected by the movement. Trailers usually take tracks under these conditions. This phenomenon is called Jack Knife. ...

Motion State Estimation for an Autonomous Vehicle- Trailer System Using Kalman Filtering-based Multisensor Data Fusion

In this research we present a Kalman filtering-based motion state estimation method for an autonomous vehicle-trailer system by fusing multiple sensor data, which can be applied directly to autonomous navigation and motion control. The autonomous vehicle-trailer system consists of an autonomous vehicle and a passive trailer which are coupled by a trailer hitch. Our vehicle-trailer system is equ...
