<p>PURPOSE:To prevent self-steering by providing a control circuit for inhibiting such a control as to generate assist torque necessary for a motor when the output of a sensor is not within the optionally decided neutral range at the time of closing a key switch. CONSTITUTION:The electric potential of a point A to the non-reverse input terminal of an operational amplifier 1 is set to be 7V from the constant voltage power supply of 12V through resistance R1, and the electric potential of a point B to the reverse input terminal of an operational amplifier 2 is set to be 5V through resistance R2. The output voltage of a torque sensor for detecting steering torque is applied respectively to the reverse input terminal of the operational amplifier 1 and the non-reverse input terminal of the operational amplifier 2.</p> |
