弁の制御装置。[Scope of Claim for Utility Model Registration] A first throttle valve that opens and closes in conjunction with an accelerator pedal, a first throttle valve opening sensor that detects the opening of the first throttle valve, and a first throttle valve that is connected in series with the first throttle valve. A second throttle valve is arranged to optimally control the slip rate; a second throttle valve opening sensor detects the opening of the second throttle valve; and a second throttle valve opening sensor detects the opening of the second throttle valve. a second throttle valve command opening calculation means for calculating the commanded opening of the second throttle valve based on the second throttle valve; a motor actuator for opening and closing the second throttle valve; The valve opening is detected by the second throttle valve opening sensor as a second throttle valve fully open opening signal, and the motor actuator is further driven to fully close the second throttle valve. The throttle valve opening is detected by the second throttle valve opening sensor as a second throttle valve fully closed opening signal, and the second throttle valve fully opened opening signal and the second throttle valve fully closed opening signal are detected. a second throttle valve opening sensor correction means for correcting the characteristics of the second throttle valve opening sensor based on the input signal from the second throttle valve command opening calculation means and the correction means corrected by the correction means; A control device for a throttle valve for a vehicle, comprising: second throttle valve control means for driving the motor actuator based on a second throttle valve opening signal.
