Abstract
Methods and systems are provided for improving vehicle speed measurements. A vehicle may detect the impact of a roadway irregularity to its front wheels and its rear wheels, and may calculate an instantaneous vehicle speed on the basis of its wheelbase and an elapsed time between the two impacts. This instantaneous vehicle speed may then be used to calculate one or more correction factors which may be used to correct a conventionally-acquired vehicle speed measurement, an operational parameter of the vehicle underlying such measurements (such as a wheel size or a final drive ratio), or both.
