PURPOSE:To eliminate meaningless variation in transmission gear ratio to obtain a transmission gear ratio corresponding to the car-speed by calculating secondary pulley-false rotating speed by false car-speed signals in a vehicle-variable speed control device provided with an antilock brake system (ABS). CONSTITUTION:An ABS control unit 70 calculates the speed, acceleration, false car-speed Vs of each wheel based on each wheel sensor. When the brake is rapidly applied, ABS control starts, variable speed control of a continuous variable transmission is temporarily reserved, actual transmission gear ratio i, target transmission gear ratio is are controlled on the basis of false rotating speed signals Ns, and variable speed control by a continuous variable transmis sion control unit 40 is performed in response to false car-speeds Vs. When output of false car-speed signals Vs from the ABS control unit 70 is stopped by releasing the braking, an output switching unit 68 outputs secondary pulley rotating speed signals Ns to return ABS control a normal variable speed control. |
