ABSTRACT:
A sensor is provided for detecting traveling speed of a vehicle, and a first deviation between the traveling speed and an estimated vehicle speed calculated beforehand is calculated. Based on the first deviation and a predetermined function, a feedback compensation output is calculated, and a second deviation between a value obtained by performing on the feedback compensation output and the aforesaid estimate vehicle speed is output as an estimated acceleration. Delay processing is performed on the estimated acceleration, and an estimated vehicle speed is updated. Noise mixed with the acceleration estimation process is eliminated, and the acceleration is thereby estimated with high precision.
