Odometry is widely used to localize wheeled and tracked vehicles because of its simplicity and continuity. Odometric calculations integrate the wheel or track’s rotation speed. The accuracy of position thus calculated, is affected by slippage between the ground and the wheel or track. When traveling on a loose slope, the localization accuracy of the odometry decreases remarkably due to slippage...

Steering wheel controls have become an essential interface for interacting with in-car human machine interfaces. The increase in both number and complexity of features in the car challenges the scalability of button-based mechanical steering wheel interfaces. Alternatives such as touch input are making their way into steering wheels of mass production cars. Multi-level force input adds a degree...

Securing appropriate driver responses to conflicts is essential in automation that not perfect (because the needed as a fall-back for system limitations and failures). However, this recognized major challenge human factors literature. Moreover, in-depth knowledge lacking regarding mechanisms affecting response process. The first aim of study was investigate how conflict while using highly relia...

The U.S. Army is examining new and evolutionary concepts for military vehicles for their future force. In particular, drive-by-wire technology coupled with non-standard driving control devices have the potential to lead to improved driving performance, reduced Soldier training time, crash prevention, smaller vehicle space claims, and improved vehicle safety in military vehicles. However, severa...

The goal of this thesis has been to study the behaviour of the closed loop driver-vehicle-environment in simulation and to find parameters of the synthetic vehicle model, which minimise certain optimisation criteria. A method of optimising parameters using genetic algorithms has been implemented and has proven to work well. Two different driving strategies have been tried in the optimisation of...

Keywords: Autonomous vehicles Genetic algorithms Fuzzy control Intelligent Transportation Systems (ITSs) Lateral control It is known that the techniques under the topic of Soft Computing have a strong capability of learning and cognition, as well as a good tolerance to uncertainty and imprecision. Due to these properties they can be applied successfully to Intelligent Vehicle Systems; ITS is a ...

This paper describes an experimental study which investigated human perception of rotational steering wheel vibration. Tests were performed with a rigid steering wheel rotating under sinusoidal excitation in the frequency range from 4 to 125 Hz at 1.86 m/s and 5.58 m/s. Twenty-five human subjects participated in the study, and two grip strengths were tested. The perceived discomfort caused by s...
