Abstract:
1. A method for measuring the temperature of a motor for a hybrid electric vehicle, the method comprising: measuring the temperature of a motor by first and second gain blocks; determining whether the measured temperature of the motor is within a low temperature range or a high temperature range; measuring the temperature of the low temperature range by the second gain block if the a starting point of the measured temperature of the motor is within the low temperature range, and measuring the temperature of the high temperature range by the first gain block if the starting point of the measured temperature of the motor is within the high temperature range; determining whether the temperature of the motor reaches an intermediate range, in which low and high temperature ranges overlap each other; correcting a deviation of the first gain block with respect to the second gain block or a deviation of the second gain block with respect to the first gain block when the temperature of the motor reaches the intermediate range; comparing the temperature of the motor with a temperature of a reference range in the intermediate range; and when the temperature of the motor is beyond the temperature of the reference range, measuring a temperature of a low temperature range by the second gain block when the temperature of the motor is below the temperature of the reference range.
