CAPS-ACC: Combined Active Passive Safety-Adaptive Cruise Control

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. 

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.

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.
