Abstract: The present invention relates to an engine control system and method for a hybrid electric vehicle. The system includes an engine, a motor mounted to one side of the engine, and a controller receiving one or more signals indicating vehicle operational conditions, and performing control of operations of the engine and motor. The controller is programmed to perform control logic (i.e., the method) that includes determining if predetermined idle stop conditions are satisfied based on the one or more signals; performing control into an idle stop state if the predetermined idle stop conditions are satisfied; and discontinuing idle stop if, following detection of a reverse range On signal, it is determined that the reverse range On signal is maintained for a predetermined time interval.

Abstract: An apparatus for controlling a motor of a hybrid electric vehicle comprises a motor control unit and an electric control unit. The motor control unit is for controlling the motor under the control of the electric control unit. The electric control unit is for calculating a motor torque based on accelerator pedal position and a change thereof. The electric control unit also executes predetermined software. The software comprises instructions for: determining an accelerator pedal position and a change thereof; calculating a motor torque based on the accelerator pedal position; low-pass filtering the motor torque based on a filtering constant selected from a plurality of predetermined constants; and, controlling the motor based on the low-pass filtered motor torque.
