Abstract
A vehicle ground-speed detecting apparatus, including a vehicle ground-speed sensor for detecting a ground-speed of a vehicle that is a speed of the vehicle relative to a road surface on which the vehicle is running, and generating an output signal representative of the detected vehicle ground-speed, and a proper vehicle ground-speed determining device for obtaining as sampling vehicle ground-speeds successive values of the vehicle ground-speed represented by the output signal from the vehicle ground-speed sensor, and determining a current one of the sampling vehicle ground-speeds as a current proper vehicle ground-speed when the current sampling vehicle ground-speed falls within a current permission range based on a current estimated vehicle ground-speed, the proper vehicle ground-speed determining device determining the current proper vehicle ground-speed by correcting the current sampling vehicle ground-speed when the current sampling vehicle ground-speed does not fall within the current permission range.
