For developing driver assistance systems which additionally require the location of pedestrians involved in road tests, GeneSys now offers a suitable, packaged solution capable of attaining a position accuracy of ± 2 cm. The key feature here is Topcon's familiar GRS-1 which was greatly enhanced in terms of functionality and adapted for use exclusively to the required application in a joint development with GeneSys.

 

One prerequisite of driving tests as part of vehicle development is to precisely determine the vehicle's position. To ensure precise positioning even under difficult GPS reception conditions, GeneSys now presents the new ADMA-PP post-processing software which allows optimization of ADMA data recordings and inclusion of GPS correction data after the test drive. 

The publication of the new ISO/DIS 26262 'Road Vehicles - Functional Safety' draft standard has raised the bar for the development of ADAS (Advanced Driver Assistence Systems), leading to an increasing demand for testing tools to validate and verify their performance. 

The publication of ISO 26262 as DIS (DraftInternational Standard) in July 2009 emphasizes the importance of Functional Safety testing. GeneSys' ADMA is part of Dewetron's FS test system, which provides the necessary objective measurement data for evaluating the controllability of a vehicle should an electronic system fail.

The paper 'How to use objective measurement data for Vehicle Dynamics Testing' by Dr. Bertold Huber, GeneSys Elektronik GmbH and Dr. Reinhard Drews, Steinbeis Transfer Zentrum Schwarzwald, both active members of the DTA, has been published in the 'SIAT 2009 Technical Bulletin'. The paper provides a condensed overview of measuring technology for vehicle dynamics investigations. 

Synchronous Measuring of Different Driving Dynamics Tasks In the past, individual suppliers were only able to cover partial spectrums of the technology required to determine all the relevant characteristics for evaluating vehicle dynamics. Customers had to make their own selections of the requisite sensors and measuring systems as well as performing installations, corrections or the interconnection of the systems themselves. Aiming to offer turnkey solutions, five companies joined forces in 2007 by founding the Driveability Testing Alliance (DTA). The central data acquisition and analysis system is one of the DTA’s core competencies. It is the first system enabling the synchronous acquisition of data from various measuring systems, which now – for the first time as well – are compatible, as proven by an initial vehicle dynamics project.

Drivability Testing Alliance, is a consortium of 5 companies:Corrsys Datron, Dewetron, GeneSys, Kistler and TÜV SÜD Automotive. As a novelty on the market the DTA offers the complete spectrum of acquisition and evaluation of vehicle driveability. The compatibility of the partner's systems and components was tested and proven so the process chain as a whole: sensor - signal processing - analysis - method development is covered.

Dr. Huber, Managing Director of GeneSys Elektronik GmbH gave a paper on ' Methods for testing of driver assistance systems' during the 5th International Mobility Conference. The conference took place on 9th, 10th and 11th January 2008 at India Habitat Center, New Delhi, India 

Evaluation Methods for the Function and Quality of Driver Assistance Systems with Active Brake Control
For the development and validation of driver assistance systems, appropriate tost, measurement and evaluation methods are necessary to evaluate and optimize the system functions under realistic scenarios. However no appropriate tost standards currently exist. TÜV Süd Automotive, an innovative development partner for the automotive industry, has developed and applied methodologies to measure, tost, analyze and evaluate these systems, based on established standards for driving dynamics. These methodologies are presented in the following excerpts. Sophisticated metrology equipment allows vehicles to be linked together in a "car to multi-car" solution. This approach enables the relative momenta to be produced dynamically and evaluated in all directions: x, y and z.

„Autonomous Driving' at Heilbronn University. The ACC (Automotive Competence Center) „Automatic Vehicle' Project
The Automotive Competence Center at Heilbronn University, founded in 2004 is engaged in various research projects in the field of automotive engineering. The Competence Center's goal is to increase expertise in the area of automotive engineering at Heilbronn University and to establish cooperation with the local supply industry. Several teams are researching into different subjects concerning the automotive industry. The 'Automatic Vehicle' project addressing driverless vehicle operation for testing of automobiles on test tracks is described in this article.

Knowledge of a track's wear condition and position is extremely important for ensuring safe transport. The rail heads of a track embedded in road pavement cannot be measured from the side. This makes it very difficult to establish the rails' wear condition. In cooperation with the public transport authorities of Erfurt, Basel and Rostock, DTK has developed a system which determines a track's position and wear by recording the rail head contours using light-section units.

down to the centimetre
When vehicles are being developed and tested, sophisticated inertial sensor systems equipped with gyroscopes and accelerometers are used to objectively map the motion of the vehicle body. The satellite navigation system GPS provides the reference to the absolute position. When these systems are used in combination, vehicle motion states can be recorded with precision and with reference to location. GPS measuring technology can be used in various ways depending on the task in hand and the required level of accuracy. As a variant on accurate position-finding, various DGPS methods are used in automotive measurement technology.

with State-of-the-Art -Technology
Good vehicle handling means active safety. Researchers must therefore continuously use methods at the limit of what is technically possible to achieve the best possible results in the analysis of driving dynamics. This new ADMA (Automotive Dynamic Motion Analyzer) gyroscopic measuring system for measuring driving dynamics can be used to record vehicle body movements precisely in conjunction with position sensing, accurate to the centimetre. The system was developed by TÜV Automotive GmbH and GeneSys Elektronik GmbH.

Finding ways of improving levels of occupant safety and standards of ride comfort are central issues for the chassis technology sector. To achieve this, an evaluation of the driving characteristics of vehicles is first required. Primarily, this involves a subject evaluation by test drivers. To assist this process, an extensive range of measuring equipment can be used to depict structural vehicle movements objectively. To achieve the best possible investigation results, methods are continuously being employed right at the outer limit of the technologically feasible. From these applications, companies such as TÜV Automotive GmbH (a division of TÜV Süd) formulate standards to guide the further development of these measuring technologies and techniques. For example, this gave rise to the requirements governing a new inertial system for measuring dynamic motion, from which GeneSys Elektronik GmbH in Offenburg developed the ADMA Automotive Dynamic Motion Analyzer.
