Automatic transmission control apparatus

摘要

An automatic transmission control apparatus secures the safe operation of a motor drive through the use of a voltage determination unit that determines which one of a voltage detected by a control apparatus voltage detection unit and a voltage detected by a motor voltage detection unit is to be utilized as a duty reference voltage. The motor control apparatus controls the motor, based on a motor drive duty that a drive duty calculation unit calculates by use of the voltage selected by the voltage determination unit.
