Abstract
A motorized vehicle capable of fault detection and of operation after a fault has been detected. The vehicle has a plurality of control components coupled to a motorized drive and a comparator for comparing the output of each of the control components with outputs of other control components so that failures may be identified. The vehicle may have multiple processors coupled to a plurality of control channels by means of a bus and a decision arrangement that suppresses the output of any processor for which a failure has been identified.
