Problems solved by technology
However, the series method does not have the working condition that the engine directly drives the vehicle. It is necessary to convert the mechanical energy of the engine into electrical energy first, and then convert the electrical energy into mechanical energy through the motor.
The energy is converted many times, and the loss is more
Parallel type and hybrid type can optimize the engine operating conditions on the basis of traditional vehicles, but they cannot completely decouple the engine operating conditions from the vehicle operating conditions, and there will still be areas with poor thermal efficiency in the engine operating conditions, so the traditional The power unit still has room for optimization

The invention discloses a hybrid drive device, a car, a control method, a device and a storage medium, wherein the hybrid drive device includes an engine, a generator, a motor, a transmission and a power distribution mechanism, and the power distribution mechanism includes two continuously variable speed change mechanisms As well as the clutch structure, each continuously variable transmission mechanism includes a driving wheel, a driven wheel and a metal belt. The driving wheel of one continuously variable transmission mechanism is connected to the engine, the driven wheel is connected to the generator, and the driving wheel of the other continuously variable transmission mechanism The drive is connected to the electric motor, and the driven wheel is driven to connect to the transmission. The clutch structure includes a first clutch and a second clutch to enable the transmission to selectively connect the engine and / or the electric motor, so that the engine speed and torque do not change or change little In the case of the vehicle, it meets the needs of different working conditions of the vehicle, improves the operating efficiency of the engine, and improves the efficiency of the drive system of the vehicle.
Description
technical field [0001] The present invention relates to the technical field of automobiles, in particular to a hybrid drive device, an automobile, a control method, a device and a storage medium. Background technique [0002] As the national environmental protection requirements become more and more stringent, automobile fuel consumption regulations are also becoming more and more stringent. Due to the working characteristics of the engine, traditional fuel vehicles have complex working conditions for customers' vehicles. Engine operating conditions need to be changed frequently, and the engine cannot always work in a high-efficiency area. Therefore, the actual comprehensive fuel thermal efficiency of traditional fuel vehicles is low, and the fuel consumption is difficult to meet the increasingly strict fuel consumption regulations. [0003] At present, the main response strategies of various OEMs are to reduce engine displacement and develop engines with higher thermal ef...
