Abstract:
A vehicle velocity detecting device for detecting vehicle velocity of a vehicle by using rotating speeds of at least four wheels of the vehicle, the vehicle velocity detecting device comprising:a wheel speed detecting unit for detecting the rotating speeds of the four wheels as respective wheel speed, individually;a turning condition detecting unit for detecting the vehicle's turning condition; anda vehicle velocity detecting unit for detecting the vehicle velocity; whereinwhen the vehicle's turning condition detected by the turning condition detecting unit is a small turning condition, the vehicle velocity detecting unit does adopt the third wheel speed from the largest one in the respective wheel speeds of the four wheels detected by the wheel speed detecting unit, as the vehicle velocity to be detected; andwhen the vehicle's turning condition detected by the turning condition detecting unit is a great turning condition containing a straight traveling condition, the vehicle velocity detecting unit does adopt the smallest wheel speed in the respective wheel speeds of the four wheels detected by the wheel speed detecting unit, as the vehicle velocity to be detected.
