Method and apparatus for motor-driven throttle valve, automobile, method of measuring temperature of motor for driving automotive throttle valve, and method of measuring motor temperature

   
   

A method is provided for easily avoiding undesirable effects on various physical values due to the change in temperature of a motor for driving a throttle valve without causing secondary problems. A technique is also provided for measuring the temperature of the motor electrically. The method uses a compensation device for correcting the power supply to the motor by detecting the impedance of the motor windings and/or the change in the motor temperature. The temperature of the motor is estimated from the current and voltage to the motor.

Un método se proporciona para fácilmente evitar efectos indeseables en los varios valores físicos debido al cambio en temperatura de un motor para conducir una válvula de la válvula reguladora sin causar problemas secundarios. Una técnica también se proporciona para medir la temperatura del motor eléctricamente. El método utiliza un dispositivo de la remuneración para corregir la fuente de alimentación al motor detectando la impedancia de las bobinas del motor y/o el cambio en la temperatura del motor. La temperatura del motor se estima de la corriente y del voltaje al motor.
