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.

Method for measuring temperature of motor for hybrid electric vehicle

The present invention provides a method for compensating nonlinearity of a resolver to control a motor in hybrid and fuel cell vehicles, thereby stably controlling the motor current during high-torque and high-speed operation. In preferred aspects, the present invention provides a method for compensating nonlinearity of a resolver to control a motor in hybrid and fuel cell vehicles, the method including collecting resolver position data; determining whether to perform resolver position correction in the corresponding vehicle; and compensating nonlinearity of the resolver based on the collected resolver position data, if it is determined that the resolver position correction is not performed.

Method for compensating nonlinearity of resolver for hybrid and fuel cell vehicles

The present invention provides an emergency control apparatus, and method which maintains the power flow between a battery and an inverter and the operation state of an electric vehicle in the event of failure of a bidirectional DC-DC converter connected between the battery as a power source and the inverter for operating a drive motor.
