A vehicle velocity detecting device is provided for a vehicle. In the device, velocity range in which a difference among respective wheel speeds is caused due to brake noise is defined as a range of speed smaller than a designated velocity V0. When an average of driving wheels' speeds VwDave is smaller than the designated velocity V0 and the vehicle is under a great turning condition containing the straight traveling condition, then the smallest wheel speed VwMIN is set to a vehicle velocity Vsp in order to exclude the wheel speed being influenced by noise. While, when the vehicle is under a small turning condition where the wheel speed of turning inside wheel is smaller in spite of the same velocity range, the third wheel speed from the largest one is set to the vehicle velocity Vsp to exclude the turning wheel speed. In the velocity range besides both turning conditions, the average of driving wheels' speeds VwDave is set to the vehicle velocity Vsp, so that it is possible to attain the vehicle velocity similar to that detected by a earlier vehicle speed sensor for converting the rotating speed of an output shaft of a transmission.
