US 6,690,174 B2 · Method and arrangement for load testing electrical systems of a motor vehicle

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.

Claims31

Dependent claims

A method for load testing an electrical system installed in a motor vehicle, comprising:

controlling at least one automatic activation device to apply a mechanical load to one or more operator control elements of the installed electrical system, thereby varying forces and moments applied to the one or more operator control elements;
and
exposing the motor vehicle and the installed electrical system to simulated ambient conditions during the load testing of the installed electrical system.

Dependencies are inferred from the claim text.
