Is the Prius hybrid system unique to Toyota?

The Prius I'm talking about is the third generation, and it is said that more than 100 patents have been used. The most advanced is that his transmission system adopts a special planetary gear transmission system, which belongs to CVT instead of our traditional clutch and transmission, but there is no reverse gear, but a motor is used to reverse the car. The engine of Prius can be turned off. Compared with Honda's two cylinders, turning off the engine directly when walking can reduce fuel consumption more effectively. This is why Toyota's hybrid is more fuel-efficient than Honda's hybrid with the same power. According to Toyota's promotional film, Toyota started the hybrid attempt of gasoline engine and electric motor from around 1975. At that time, their plan was to use gasoline generators to generate electricity and provide motor power. From 65438 to 0997, Toyota introduced the world's first mass-produced hybrid car, which is the first generation of the famous Prius. Therefore, it can be seen that Toyota's research and attempt on hybrid vehicles came earlier than other companies.
