Description

Hybrid power control system and vehicle

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 26, 2023, with application number 202310753512.4, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of vehicle engineering technology, for example, to a hybrid power control system and a vehicle. Background Art

[0003] As emission and fuel consumption regulations become increasingly stringent, energy conservation and emission reduction have become the primary goal of vehicle development. There are more and more alternatives to fuel engine vehicles, but hybrid vehicles are currently the most practical.

[0004] Engines (also known as internal combustion engines) include naturally aspirated engines and supercharged engines. Supercharged engines are further subdivided into exhaust gas turbocharging and electric supercharging technologies. Exhaust gas turbocharging primarily utilizes exhaust energy to drive the supercharger. However, its disadvantage is that at low engine speeds, the exhaust flow rate is insufficient, and the supercharger blocks exhaust gas discharge, resulting in insufficient system power. Electric supercharging primarily uses a drive motor to drive the supercharger, but the drive motor has a low speed and light load, resulting in a weaker supercharger.

[0005] Hybrid power systems typically feature a drive motor and generator. Placing the drive motor in different locations within the hybrid power system creates diverse structural configurations, enabling various operating modes based on the vehicle's operating conditions. However, the drive motor can only drive the vehicle or increase engine speed, and due to the performance characteristics of a single motor and engine, it cannot cover a wide range of the power source's efficient operating range.
