Modes of Operation: Hybrid

The system operates in this mode when the engine is running and powering the electric motor which produces the electricity. The electricity produced by the electric motor charges the high voltage battery. In this mode the electric motor can operate as a motor or as a generator to make up the difference between engine torque and desired torque at the wheels. This mode is preferred whenever the electric battery needs to be charged or at moderate loads at low speeds.

• Drive - The engine drives the transmission providing torque to the wheels meeting driver demand. Requested torque above this demand is used to charge high voltage battery through the electric motor. Electric motor can also assist engine.
• Driven - The transmission is driven by inertia of vehicle and provides regenerative energy to electric motor meeting all or a portion of the braking demand. Engine can provide compression braking.
