What is the principle of Toyota dual-engine hybrid?

The principle of Toyota dual-engine hybrid is as follows: 1. Start-up: When the hybrid dual-engine power system starts the vehicle, the engine does not work, and the vehicle can be started sensitively and smoothly only by relying on the motor that can provide the maximum torque instantly. 2. When driving at medium speed: before the vehicle starts and reaches a certain speed, the engine is still not running, and the vehicle is only driven by the motor. Until the engine efficiency and high speed are reached, only the electric energy of the battery is used to drive the vehicle. So we don't consume gasoline at this time. The actual situation of the vehicle, the engine may also run at the same time. 3. When driving: use the motor and engine at the same time, and always keep the output power and fuel economy in the best state. After the engine is started, according to the actual driving situation, two kinds of power, "directly driving the wheels" and "used for power generation", are automatically distributed. Toyota's hybrid dual-engine power system is not only used to drive vehicles, but also loaded with motors specially used for power generation. Relying on this original technology, the power of the engine and the auxiliary power provided by the motor can be skillfully combined and used efficiently. At the same time, by accurately controlling the distribution of these two kinds of power, the best energy efficiency can be achieved. 4. When driving at full speed: When overtaking requires strong acceleration, the engine and motor are used at the same time to achieve strong and stable acceleration performance. By using dual power, the acceleration performance of Toyota's hybrid dual-engine power system is higher than that of ordinary cars with the same displacement. 5. Deceleration braking: When the pedal is braked under the tower, the motor can be converted into a generator, and the recovered energy can be stored in a high-voltage battery. When an ordinary car slows down, the mechanical motion energy of the car after braking friction will be converted into heat energy and dissipated into the atmosphere. Toyota's hybrid dual-engine power system can convert the mechanical motion energy of vehicles into electrical energy and reuse it.
