Definitions
- the invention belongs to the technical field of hybrid power, in particular to a hybrid power drive system and a hybrid car.
- the drive system of hybrid electric vehicles mainly includes three basic forms of series, parallel and hybrid (power split type).
- series connection there is no mechanical connection between the engine and the output shaft, which can realize the optimal control of the speed/torque, but all its energy needs to be transferred to the output shaft after two conversions between mechanical power/electric power, and the loss is large .
- the parallel transmission has high efficiency, but the mechanical connection between the engine and the output shaft cannot guarantee that the engine is always in a better working area, and is usually used for medium and high speeds.
- Hybrid connection combines the advantages of series and parallel, not only can realize the optimal control of the engine, but also can achieve the high-speed and high-efficiency control, but when the vehicle starts, the motor has high power requirements and low efficiency. It can be seen that the ideal driving scheme is based on a hybrid hybrid drive system, which realizes the functions of pure electric starting, low- and medium-speed power splitting, direct-drive or parallel drive of medium- and high-speed engines.
- the hybrid hybrid drive system mainly uses a planetary mechanism as a power shunt device, which is divided into four basic forms of input shunt, output shunt, composite shunt and combined shunt according to the position of the motor and engine in the mechanism.
- the mainstream planetary hybrid drive systems are: First, the Toyota THS (HSD) single E-CVT mode hybrid system is used to carry Toyota Prius, Corolla, Ralink, Camry, Lexus HS250h and Highlander, and Ford Escape And other models.
- the second is the universal single E-CVT mode and dual E-CVT mode hybrid system, used to carry Volanda, Escalade and Mercedes-Benz ML450 and other models.
- Toyota hybrid system can realize pure electric, E-CVT hybrid mode and regenerative braking mode. According to the different vehicle models, it is divided into single planetary row system and double planetary row system. Its purpose is to increase the transmission torque of the drive motor end and reduce the torque of the drive motor by adding a planetary gear reduction ratio (1+k) (Especially for pure electric starting conditions), thereby reducing the size and weight of the drive motor.
- the universal E-CVT mode hybrid system can realize pure electric, E-CVT hybrid and regenerative braking modes. According to the different vehicle models, it is divided into single planetary row, double planetary row and three planetary row systems.
- the single E-CVT mode hybrid system under the low-speed and high-speed operating conditions, the transmission power of the electrical circuit occupies a relatively large amount compared to the mechanical circuit. After two conversions from mechanical power to electric power, and then from electric power to mechanical power, the loss is large, and the system efficiency is low.
- the pure electric mode can be used in low-speed operating conditions to avoid the use of E-CVT mode and improve the system efficiency, for high-speed operating conditions, the system can only use the only E-CVT mode.
- GM has developed a dual E-CVT mode, but when the vehicle speed rises to a certain degree and the speed ratio exceeds its second E-CVT mode's second mechanical point speed ratio, the transmission efficiency of the hybrid power system will Will fall. It can be seen that the transmission efficiency of the hybrid power system in the prior art is not high.
