What is the principle of the Toyota Camry Hybrid?
2 Answers
Toyota Camry Hybrid adopts a series-parallel hybrid system. In its power coupling mechanism, the motor MG1 and the engine need to undergo planetary gear speed coupling. After speed coupling, torque coupling with motor MG1 is also required. Through speed synthesis, motor MG2 adjusts the engine speed, making the engine speed independent of the vehicle speed, thereby achieving the ECVT function. The Camry is a model under GAC Toyota. In terms of body dimensions, it measures 4900mm in length, 1840mm in width, and 1455mm in height, with a wheelbase of 2825mm.
Having driven the Toyota Camry Hybrid for many years, I've gradually figured out its principles, which are quite fascinating. The core idea is to combine electric and gasoline power. At startup or low speeds, it mainly relies on the electric motor for propulsion, making the cabin exceptionally quiet and fuel-efficient. When accelerating, the gasoline engine automatically kicks in, providing seamless power transition. Even more impressively, during braking or coasting, the system recovers energy and stores it in the battery for reuse. In city traffic with constant stop-and-go, fuel consumption drops significantly, possibly as low as 5 liters per 100 kilometers. The battery is located under the trunk, saving space, so the rear seats remain spacious and comfortable. The engine engagement is smooth, and it's also quite economical on long highway drives. Overall, this design makes driving more economical and environmentally friendly, and I feel it's much smarter than pure gasoline cars.
