ABSTRACT:
A vehicle speed is obtained from detection signals obtained from wheel speed sensors. In a case where a vehicle speed calculation is shifted from a first method to a second method, a vehicle speed displayed on a speedometer is gradually changed from the vehicle speed obtained by the first method to the vehicle speed obtained by the second method. This avoids abrupt change in the displayed vehicle speed causing the driver to feel discomfort.
