Comparison of in-car touchpads with adaptive haptic feedback

Year: 2012

Authors: A Blattner,K Bengler, W Hamberger

Two in-car touchpads with adaptive haptic feedback are specified in the context of this contribution. These innovative control elements enable an easy and intuitive handling of modern car infotainment systems. The current paper presents the results of a field experiment comparing a touchpad with realistic haptic feedback via sensible and operable elements to a touchpad with haptic feedback via vibration of the touchpad surface in a real driving situation.

Evaluation of Automotive HMI Using Eye-Tracking-Revision of the EN ISO 15007-1 & ISO TS 15007-2

Year: 2012

Authors: C Lange

This paper presents the revision of documents EN ISO 15007-1 and ISO/TS 15007-2 which was done by the ISO TC22SC13WG8 working group consisting of eye-tracking specialists worldwide. Both ISO documents were published in 1999. Since then many research studies were conducted, which lead to an increasing level of knowledge about eye-movement behavior. In parallel to that, eye-tracking technology developed enabling fully automated data analysis. Due to that both standards were revised in the ISO TC22SC13WG8 working group to include latest findings in eye-movement behavior and latest developments in eye-tracking technology.

Development of Distraction-free control systems in a Driving simulator

Year: 2011

Authors: C Lange,K Bengler, R Spies, M Wohlfarter

Ensuring driver safety by minimizing distraction is crucial in the development of in-vehicle information and communication systems. The article discusses the design and evaluation of control systems intended to reduce driver distraction, leveraging a driving simulator for the research. The work examines various standards and guidelines for in-vehicle display systems, as well as metrics for assessing driver distraction and cognitive workload. The goal is to enhance road safety through improved driver assistance systems, such as adaptive cruise control, by ensuring that they do not overly tax the driver’s attention. The findings are based on extensive behavioral and eye-tracking studies conducted in a simulated driving environment.

The influence of predictability and frequency of events on the gaze behaviour while driving

Year: 2011

Authors: R Kaul,M Baumann,B Wortelen

One possible reason for rear-end crashes might be that the driver is distracted as the driver does not pay enough attention to the driving task. Therefore allocation of attention must be appropriate to the demands of the current traffic situation. According to the SEEV-Model allocation of attention is determined by the expectancy that there will be new information in a visual channel. According to the model expectancy is determined by the event rate of the information. To investigate to what extent allocation of attention is determined by the absolute frequency of events or by the expected event rate an experiment was conducted in a dynamic driving simulator. The current results show that the predictability of the behaviour of the lead car has a bigger influence on the allocation of visual attention than the frequency of speed changes of a lead car and the frequency of a visual secondary task.

Effects of assistance of anticipatory driving on driver’s behaviour during deceleration phases

Year: 2010

Authors: D Popiv,C Rommerskirchen,K Bengler

In this work, the investigation of the assistance of anticipatory driving is presented. The goal is to explore the effects of such an assistance system on driver’s behaviour in deceleration situations. The influence of the system is derived using the comparison between assisted and unassisted drives performed in a fixed-base simulator. The benefits are evaluated via analyzing driving and visual data with respect to safety, comfort, and efficiency criteria. The results show that drivers with assistance start decelerating significantly earlier in some of the investigated situations, predominantly by coasting a vehicle. The mean maximum decelerations are reduced from 8.5m/s2 to 6.2m/s2 in the safety critical situation, and the fuel consumption tends to sink on 4% in the entire drive.

Reduction of fuel consumption by early anticipation and assistance of deceleration phases

Year: 2010

Authors: D Popiv,K Bengler, M Rakic

This work deals with the investigation of advanced driver assistance system (ADAS) which helps the driver to perform phases of deceleration in an efficient and safe manner. The concept of the assistance system is supported by early recognition of deceleration situations with the help of new sources of traffic information such as GPS based systems, car-to-car, and car-to-infrastructure communication. The system presents visual information to the drivers in order to enhance their anticipation. Together with the representation of emerging situation, the assistance suggests coasting a vehicle from the currently driven speed to the upcoming lower goal speed in order to reduce fuel consumption. If coasting does not suffice, the system will suggest moderate braking. It is left to the driver‟s consideration to accept the system‟s advice. The analysis of the estimated fuel consumption and the acceptance of the assistance system are done using situational, driving, visual, and subjective data which were collected during the experiment drives in the fixed-base simulator. Twenty six test subjects took part in the experiment; their average age was thirty four years. After a simulator training, they had to complete three experiment drives in the permuted order each lasting between seventeen and twenty minutes: one drive without any assistance (baseline condition), one with the innovative visual assistance using a bird‟s eye-view perspective on the emerging deceleration situation, and one with an iconic representation of it. Visual concepts are displayed in the digital instrument cluster. Each drive consists of thirteen deceleration situations which occur on rural, highway, and city roads. This work presents the results regarding the influence of the system on the driving behavior. The analysis data of two assisted drives are compared to the baseline condition. The results show the significant reduction of the estimated fuel consumption in particular situations (up to 50%) and in the entire drive (approximately on 4%). Maximum decelerations are significantly reduced in the investigated safety critical situation. The drivers are able to avoid collisions, which happened during baseline drives.

Integration of a Component Based Driving Simulator and Design of Experiments on Multimodal Driver Assistance

Year: 2006

Authors: D Popiv

Fully automated driving is a future goal of research currently performed in automotive industry. Therefore this thesis deals with driving support systems on different levels of automation. Fully integrated multimodal approaches for such driving systems aim at providing intuitive means for minimally distractive assistance for car drivers. In this thesis, the description of design and implementation of three concepts of driving support systems in the driving simulator is given. The driving support systems are based on three concepts. Every concept represents assistance on different level of driving automation. A non-automated concept is based on the principle of driving activity without an automation support provided to the driver. A semi-automation support system is represented by the concept of Active Cruise Control, in which driver performs a role of a system’s supervisor and delegates part of the driving tasks to the system. The third concept is the concept of Active Gas Pedal. In terms of this concept driver is offered support on behalf of the driving system, but still is required to perform tasks of driving personally. Also lateral and longitudinal visual assistance is incorporated into the implementation of the three described concepts. To test mentioned concepts, a fixed-base driving simulator was set up, the architecture of which is explained in this thesis as well. The set-up of the fixed-base driving simulator, its hardware components, corresponding interfacing software applications, and their networking are described. The software system architecture in the driving simulator is explained, and development process of the driving support systems is introduced. Also, needed implementation information is provided for further extensions of the software system. Finally the experimental design for the user study is described, so that the experiment only needs to get executed.
