DRIVING POINT CONTROL SYSTEM OF HYBRID VEHICLE AND A METHOD THEREOF CAPABLE OF PROVIDING TORQUE CONTROL WHICH HAS AN OPTIMAL DRIVING POINT

摘要

PURPOSE: A driving point control system of hybrid vehicle and a method thereof are provided to provide torque responsibility and ride quality by processing optimal driving control.;CONSTITUTION: A driving point control system of hybrid vehicle includes a controller(40). If an engine turns on or off by a first motor(21), the controller detects speed of the first motor in order to extract an accelerating torque. The controller detects the speed of the first motor and extracts the accelerating torque. The controller decides gain of the accelerating torque by applying speed of a driving mode and the engine. The controller applies accelerating torque and gain to the actual torque of the first motor. The controller calculates amount of the engine torque variation according to drive of the first motor.;COPYRIGHT KIPO 2012
