A method of and an apparatus for estimating a vehicle velocity, which are suitable for use in a vehicle. Velocities of drive wheels and follower wheels of the vehicle are determined and the fastest one of the so-determined velocities is selected. The velocity of the vehicle is estimated based on the fastest wheel velocity thus selected. The above respective processes are repeatedly executed at given time intervals. Thus, when the estimated vehicle velocity is faster than each of the velocities of the follower wheels and lower than the fastest wheel velocity, the estimated vehicle velocity determined immediately before the above estimating process is set as a desired estimated vehicle velocity. Accordingly, a high-accuracy estimated vehicle velocity corresponding to an actual vehicle velocity can be obtained, thereby making it possible to control brakes and driving forces with high accuracy using the estimated vehicle velocity.

Méthode et appareil d'estimation de la vitesse d'un véhicule, utilisables dans un véhicule. On détermine les vitesses des roues motrices et des roues suiveuses du véhicule et on choisit la vitesse la plus élevée qui servira à estimer la vitesse du véhicule. On répète le processus ci-haut mentionné à des intervalles de temps déterminés. Par conséquent, lorsque la vitesse estimée du véhicule est plus élevée que celle de chacune des vitesses des roues suiveuses et moins élevée que la vitesse de la roue la plus élevée, l'estimation de la vitesse du véhicule déterminée immédiatement avant le processus mentionné ci-haut est fixée comme la vitesse estimée du véhicule désirée. On peut ainsi obtenir une vitesse estimée de véhicule se rapprochant de celle du véhicule réelle, permettant de contrôler les freins et les forces motrices avec une grande exactitude en utilisant la vitesse estimée du véhicule.
