Hybrid power driving device, automobile, control method and device and storage medium

Abstract

The invention discloses a hybrid power driving device, an automobile, a control method and device and a storage medium. The hybrid power driving device comprises an engine, a generator, a motor, a transmission and a power distribution mechanism, wherein the power distribution mechanism comprises two stepless speed change mechanisms and a clutch structure. Each stepless speed change mechanism comprises a driving wheel, a driven wheel and a metal belt, the driving wheel of one stepless speed change mechanism is in driving connection with the engine and the driven wheel is in driving connection with the generator, and the driving wheel of the other stepless speed change mechanism is in driving connection with the motor and the driven wheel is in driving connection with the transmission; the clutch structure comprises the first clutch and the second clutch and is used for enabling the transmission to be selectively connected with the engine and / or the motor, different working condition requirements of the whole vehicle can be met under the condition that the rotating speed and the torque of the engine are not changed or slightly changed, and the operation efficiency of the engine is improved. In addition, the efficiency of the whole vehicle driving system is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hybrid driving 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. The engine operating conditions need to change frequently, and the engine cannot work in an efficient zone all the time. Therefore, the actual comprehensive fuel thermal efficiency of traditional fuel vehicles is low, and the fuel consumption is difficult to meet the increasingly stringent fuel consumption regulations. [0003] At present, the main countermeasures of various OEMs are: first, reduce engine displacement and develop engines with higher thermal efficiency; ...

AI Technical Summary

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
