Title:
バルブ位置制御装置
Document Type and Number:
Japanese Patent JP4428163
Kind Code:
B2
Abstract:
The throttle position corresponding to the rotational angle of the throttle valve is calculated based on electric signals output from a rotor position detector constituted by three Hall ICs that detect the rotational position of a magnet rotor of a brushless DC motor. A valve position control quantity of the throttle valve is so calculated as to eliminate the difference between the thus calculated valve position and a target valve position. The motor current control quantity of the brushless DC motor is so determined as to eliminate the difference between the calculated valve position and the target valve position. Though the throttle position sensor is omitted, the electric signals output from the rotor position detector are used for calculating both the valve position control quantity and the motor current control quantity.
