What is the principle of Toyota's hybrid technology?

The principle of Toyota's hybrid technology is quite complex. It mainly uses a combination of electric motors and engines to drive the vehicle. When the throttle is released, the engine will shut down, and the energy回收 from the wheels is used to charge the battery. Toyota's hybrid system consists of two electric motors and one engine. One of the electric motors is directly connected to the engine, while the other is not. The most critical design of Toyota's system is the compound planetary gear box. The engine and the electric motor connected to it form a driving unit, and the other electric motor forms a second driving unit. These two units can be flexibly allocated by the vehicle's computer, and the transmission system is used to transfer power to the driving wheels. When accelerating, the first driving unit transmits power to the wheels through the transmission system. In pure electric mode, the second driving unit replaces the engine and electric motor and provides power to the wheels independently. When the battery is full, the engine's energy is transmitted to the electric motor connected to it to assist in reducing the speed of the vehicle. Therefore, when driving a Toyota hybrid vehicle, you don't need to be sensitive to the brake pedal, as the electric motor provides enough stopping power. Only the original brake system is needed in case of parking or emergency situations. This system has created the basis for the computer-controlled linear brake and throttle systems.
