  • Method and arrangement for load testing electrical systems of a motor vehicle
    Patent number: 6690174
    Abstract: The invention relates to a method and arrangement for load testing electrical systems of a motor vehicle. The operator control elements of the electrical systems are activated via an externally controlled robot during a test period of typically 7 to 14 days. The motor vehicle containing the electrical systems is located during the test in a simulation chamber in which the temperature and/or atmospheric humidity can be set by an air-conditioning system, and simulated solar radiation are set by one or more radiators. In addition, acceleration forces occurring during driving are simulated via a road simulator. The forces and moments occurring when the operator control elements are activated are preferably sensed and recorded for analysis and evaluation.
