Abstract
A method and system for controlling a drive motor are provided. The method includes determining whether a vehicle is at a sudden braking event by detecting a brake depth of a brake pedal and calculating a depth rate of the brake pedal based on the detected brake depth. In addition, the drive motor is operated to reduce regenerative braking torque when the vehicle is determined to be at the sudden braking event.
