Title:
POWER SYSTEM OF HYBRID ELECTRIC VEHICLE AND POWER TRANSMISSION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/076893
Kind Code:
A1
Abstract:
A power system of a hybrid electric vehicle and a power transmission method therefor. The system comprises: an engine (10), a speed shift (30), a clutch (40), a power switch apparatus (90), a transmission mechanism (80), a power output shaft (50) and a motor (20). The power switch apparatus (90) is a synchronizer or clutch, for switching the motor torque between the transmission mechanism (80) and the power output shaft (50). When a vehicle is in a state where it is stationary and the engine is started, the vehicle is in a power generating state where it is stopped, or the vehicle is in a power generating state where it creeps, the motor (20) is connected to the transmission mechanism (80) and the powers of the engine (10) and the motor (20) are mutually coupled, achieving quick engine starting, quick power generation where the vehicle is stopped and quick power generation where the vehicle creeps; in the state of gear shift of the speed shift (30), the motor (20) is connected to the power output shaft (50), and the motor (20) provides a compensated torque to the power output shaft (50), such that gear shifting without torque break is realized. The system can realize quick engine starting, quick power generation where the vehicle is stopped and quick power generation where the vehicle creeps, and gear shifting without torque break.
