The test system from Dewetron measures vehicle data that includes CAN. To measure the exact position and movement of the vehicle, an ADMA system from Genesys Elektronik is used.
Due to the increasing number of electronic systems in cars, the importance of functional safety is also growing. A malfunction for example in an ABS system could result in a dangerous situation. As the international safety standard IEC 61508 is very difficult to apply to automotive applications, the added standard ISO 26262 on functional safety, which has been developed especially for the automotive industry, comes into effect. To test the controllability of a vehicle to prove functional safety aspects according to ISO 26262, different driving maneuvers with simulation of sensor malfunctions are performed.
The test system DEWE2-A4-ADAS, measures all vehicle data including CAN, exact positions, and internal data of the ABS/VDC systems during the maneuvers. To measure the exact position and movement of the vehicle, an ADMA (automotive dynamic motion analyzer) system from Genesys Elektronik is used.
ADMA combines GPS data with inertial sensors resulting in a precision in the range of a few centimeters. The basis for objective results are synchronized measurements of different data like GPS, high performance INS/GPS system for motion analysis and precision position measurement, analog sensors (voltage, acceleration, strain, etc.), counter, CAN, Flexray, ABS/VDC internal data via XCP, or even video.
