<P>PROBLEM TO BE SOLVED: To provide a vehicle speed estimation system for checking if a vehicle speed is correctly estimated. <P>SOLUTION: This system is provided with a means for estimating speed of a car (1) to determine the 1st parameter based on a rotational speed of the 1st set wheels (5) in the car such as drive wheel, etc., and a (v<SB>estimate</SB>) means for estimating a speed of a car by using the above 1st parameter. Additionally the system has a means for determining the 2nd parameter based on a rotational speed of the 2nd set wheels (4) in the car, and a means for identifying the difference between the 1st and 2nd parameters, if any. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
