Automotive Rollover Angular Rate Sensors and Evaluation 1999-01-0430
This paper presents a test methodology for evaluating angular rate sensors used for detecting vehicle rollover. The key electrical parameters over temperature are tested with a rate table. Immunity to linear accelerations is evaluated at room temperature with a vibration table and a thruster. The vibration test provides mechanical resonance information and rough road performance, while the thruster test provides g-sensitivity parameters under severe impact conditions such as with vehicle frontal and side impact events. The vehicle level evaluation includes severe vehicle maneuvers, rough road and gravel road tests, as well as full-scale vehicle rollover tests.
