Abstract: A longitudinal vehicle speed sensor for a vehicle includes a first sensor configured to generate a first measured speed based on one of a wheel speed of the vehicle receiving output torque from a drive unit and an output of a global positioning system (GPS). A second sensor is configured to generate a second measured speed. A speed weighting module is configured to apply a first weight to the first measured speed to generate a first weighted speed. A speed weighting module is configured to apply a second weight to the second measured speed to generate a second weighted speed. An output module is configured to generate a speed estimate based on the first weighted speed and the second weighted speed.
