About the session
Electromagnetic systems depend upon the integrity of electrical connections. An intermittent speed sensor connection is shown to generate a false speed signal that may allow an automobile speed control system to engage at low speed and cause a sudden acceleration. Preventive measures are discussed. The current approach to controlling uncommanded sudden accelerations seems to rely upon the driver braking against full engine power to bring the vehicle to a halt. More effective and safer control would be achieved by cutting off the fuel supply the moment that an uncommanded wide open throttle condition was detected, thereby preventing the sudden acceleration.
