More and more automotive applications now employ motors for enhanced automation – in areas such as locking mechanisms, mirror adjustment and parking, cooling fans and so on. And while problems with these systems would be a nuisance, in most cases they would not have a significant impact on safety.
However, motors are also used in safety critical automotive applications. As an example, to move the throttle body, to control the power steering or to position the driver’s seat. Unexpected or uncontrolled operation of any of these would have potentially catastrophic consequences to a vehicle in motion.
