Method and system for controlling drive torque of vehicle
First Claim
1. A method of controlling a drive torque of a vehicle, comprising:
- calculating, by a controller, a drive request torque of the vehicle;
calculating, by the controller, drive power displayed on a drive power gauge of an instrument cluster based on the calculated drive request torque;
adding, by the controller, a predetermined additional torque to the drive request torque when the calculated drive power displayed on the drive power gauge enters a predetermined zone of the drive power gauge;
mapping, by the controller, the drive request torque corresponding to signals of the vehicle speed sensor and the accelerator pedal sensor;
calculating, by the controller, drive power based on the mapped data of the drive request and the signal of the vehicle speed sensor;
filtering, by the controller, the calculated drive power by a signal displayed on the drive power gauge of the instrument cluster;
calculating, by the controller, an additional torque to be added to the drive request torque based on an output drive power display signal;
adding, by the controller, the calculated additional torque unit and the mapped drive request torque; and
distributing, by the controller, the output added torque to the engine and the drive motor.

Abstract
A method and a system that control a drive torque of a vehicle in which there is a change in a torque of a predetermined magnitude when drive power of the vehicle enters a zone in which a predetermined maximum output is generated to allow a driver to feel that the drive power of the vehicle enters the maximum output zone during traveling. The method may include calculating, by a controller, a drive request torque of a vehicle and calculating drive power displayed on a drive power gauge of an instrument cluster based on the calculated drive request torque. In addition, the method may include adding, by the controller, a predetermined additional torque to the drive request torque when the calculated drive power displayed on the drive power gauge enters a predetermined zone of the drive power gauge.
