ABSTRACT:
A vehicle speed display device includes a plurality of speed sensors of different types for detecting the speed V of a vehicle by different detection methods. A selector mechanism accesses error maps associated with each of the speed sensors that reflects inaccuracies characteristic of the associated speed sensors under various conditions, such as at various speed and/or at various acceleration levels. The selector selects a speed value associated with a minimum error value for the current moving state conditions and the selected speed value is displayed to an operator of the vehicle.
