What is the principle of Toyota's hybrid technology?

Toyota's hybrid technology principle: It uses a method of series and parallel connection between the motor and the engine to drive the vehicle. When the throttle is released, the engine will shut down, thus utilizing the wheels to recover energy and store electricity in the battery. The Toyota hybrid system consists of two electric motors and one engine, with one of the electric motors directly connected to the engine, while the other is not directly connected. Toyota Motor Corporation is an automobile manufacturing company, and its products include models such as the Crown, Reiz, Prius, Corolla, and Camry. Taking the Camry as an example, its body dimensions are 4885mm in length, 1840mm in width, and 1455mm in height, with a wheelbase of 2825mm. In terms of appearance, the Camry features dual styling designs: a luxury version and a sport version, both derived from Toyota's "Keen Look" design language. Taking the Camry luxury version as an example, it adopts a large trapezoidal horizontal grille, with a streamlined body posture, lower waistline, and an extended roof rear section that increases rear headroom.
After driving a Toyota hybrid for ten years, I've discovered its fuel-saving secret lies in the power distribution system. Simply put, the engine and two electric motors are connected via a planetary gear set, which functions like an intelligent traffic control center. During startup or low-speed driving, it operates purely on electric power, making it quiet and fuel-efficient; when acceleration is needed, both the motor and engine work together; during steady-speed cruising, the engine can even charge the battery. The most ingenious part is the regenerative braking system, where every time you brake, it's actually charging the battery. The battery itself is a low-maintenance nickel-metal hydride type, which hasn't needed replacement even after 150,000 kilometers. This system keeps the engine operating in its most efficient range, achieving over 30% better fuel economy than conventional vehicles.
