Abstract
The present invention provides a method of controlling a driver request torque in a hybrid electric vehicle, in which a driver request torque is calculated by determining that a driver has an intention to accelerate, if an accelerator opening degree detected by an accelerator pedal position sensor (APS) is greater than 0% when the accelerator pedal is depressed by the driver who intends to re-accelerate after coasting or decelerating, and a torque discontinuity, which may be caused when the APS is turned on→off→on according to the depression operation of the accelerator pedal by the driver, is controlled using an up/down torque rate limit logic, thus preventing deterioration of driving performance.For this purpose, the present invention provides a method of controlling a driver request torque in a hybrid electric vehicle, the method including: monitoring a vehicle speed; calculating a maximum torque with respect to the vehicle speed; monitoring an APS; and calculating a driver request torque by determining that a driver has an intention to accelerate and recognizing a minimum request torque as 0 Nm, if an opening degree of the APS is greater than 0%.
