摘要： The present invention provides a method for controlling motor torque in a hybrid electric vehicle, which can reduce current control mapping time and simplify control algorithm by providing a torque control compensation logic against a change in temperature of a motor (interior permanent magnet synchronous motor) of the hybrid electric vehicle. The present method includes: forming a single current control map based on an engine room temperature; determining a motor operation range that requires temperature compensation according to motor load conditions such as speed and torque; obtaining an optimization formula for torque command compensation; determining a torque command compensation value using the optimization formula; generating a new torque command with the torque command compensation value and applying the new torque command to the single current control map; and applying to a motor a current for which a torque variation according to a temperature change is compensated.
