Claim 14:
15. A method of controlling an electric vehicle having first and second electric machines, the method comprising:
selecting one of first and second speed sensors based on (i) a difference between a speed value for the that speed sensor and an average speed for both of the speed sensors and (ii) a noise factor associated with the one of the speed sensors;
commanding speeds to the first and second electric machine based on a difference between a target speed of the electric machines and a measured speed of the one of the first and second speed sensors but not the other of the first and second speed sensors; and
in response to the electric machines being commanded to an idle speed, selecting one of the first and second speed sensors having a greatest number of accumulated points for a first predefined sampling duration occurring when at the idle speed, wherein the accumulated points of the second duration for each of the first and second speed sensor is based on (i) a variance that is a ratio of a speed value for that speed sensors and an average speed for both of the speed sensors and (ii) a noise factor associated with that speed sensor.
