More Information
Summary:The present invention provides a method for measuring the temperature of a motor for a hybrid electric vehicle. In preferred embodiments, the method of the present invention can preferably ensure the stability and reliability of motor control by extending the linearity of a temperature sensor attached to the motor within a required measurement range. The present invention preferably provides a method for measuring the temperature of a motor for a hybrid electric vehicle, in which a required measurement range of motor temperature is divided into high and low temperature ranges and a hardware gain circuit is divided into first and second gain blocks such that the first gain block measures the temperature of the high temperature range and the second gain block measures the temperature of the low temperature range.
