MAKING A VEHICLE SAFETY SYSTEM MORE RELIABLE
Developing a way to tell the difference between normal vibration and a genuine vehicle tip-over.
THE CHALLENGE
An electronic sensor was giving misleading readings when the engine vibrated. The system needed to recognize a real tip-over without raising false alarms during normal riding.
OUR APPROACH
Studied the existing electronics, developed new software, collected data on the vehicle, compared settings in a computer simulation and tested the revised system again.
THE OUTCOME
Testing showed much steadier readings during normal operation and a response delay of less than about 1.5 seconds in controlled tip-over tests. The work also showed when more advanced sensors would be needed.
