Method for testing the influence of electromagnetic energy on a vehicle safety sytem during a crash event
First Claim
1. A method of testing a vehicle safety system that has at least one sensor and at least one controller, comprising:
- obtaining EMI data indicating the performance of the sensor and controller when the safety system is exposed to electromagnetic energy;
obtaining crash data indicating the performance of the safety system during at least one crash event; and
determining the performance of the safety system during a crash when the system is exposed to electromagnetic energy using the EMI data and the crash data.

Abstract
A vehicle safety system testing method provides an indication of how the safety system responds during a crash event while the system is exposed to electromagnetic energy. The system is exposed to electromagnetic energy to obtain EMI data indicating the system performance under those conditions. Separate crash data indicating the system response to a crash event is obtained using computer simulation or known test equipment. The EMI data is superimposed onto the crash data to provide an indication of how the system performs when exposed to both conditions. In one example, the EMI data is superimposed onto the crash data and the resulting data is provided to the system controller so that the controller response can be determined. In one example, the ability of the system to accurately issue deploy commands to an airbag squib is tested at selected EMI frequencies.
