초록 ▼

An electric motor system for reducing drive wheel torque on a hybrid electric vehicle includes an internal combustion engine, an electric motor, a transmission, and a controller. The internal combustion engine is located in the hybrid electric vehicle and generates an engine torque. The electric motor is coupled to the internal combustion engine and generates and electric motor torque. Both the engine and motor are coupled to the transmission that uses the combined torque from both the engine and motor to generate drive wheel torque on a drive wheel. The vehicle system controller is coupled to the electric motor and senses any traction control events. When a traction control event occurs the controller commands the electric motor to reduce the drive wheel torque by reducing the electric motor torque.
