Abstract

The invention provides a hybrid power transmission, a control method and a vehicle. The transmission comprises an engine, a differential mechanism assembly, a motor, a transmission mechanism and a battery connected with the motor. The transmission mechanism comprises a power output shaft connected with the differential mechanism assembly, double clutches connected with the engine, a power input shaft assembly connected with the double clutches, a plurality of gear gear pairs connected between the power output shaft and the power input shaft assembly in a coupling mode, and a gear synchronizerarranged on the power output shaft and used for achieving gear synchronization. The motor is connected with the power input shaft assembly through the transmission assembly. Mode switching is achievedthrough the double clutches and the synchronizer, the system structure is simplified, and the total length of the transmission is shortened; in addition, a specific transmission mechanism is arrangedto be matched with the double clutches, the synchronizer, the engine and the motor, matching of driving modes is more diversified, the system has all functions needed for improving the fuel economy,and therefore the fuel economy of the vehicle is effectively improved.

Description

technical field [0001] The invention relates to the field of hybrid power technology, in particular to a hybrid power transmission, a control method and a vehicle. Background technique [0002] Today's world is facing the two major challenges of energy scarcity and environmental degradation. Traditional fuel vehicles are being severely troubled by the oil crisis and environmental degradation. Energy conservation and emission reduction have gradually become the focus of the automotive industry. The emergence of hybrid electric vehicles has brought new hope for alleviating energy shortage and environmental degradation. [0003] Among them, the hybrid transmission is the core component of the hybrid vehicle and the power source of the hybrid vehicle. In a hybrid transmission, it generally includes a motor and an engine. The motor is driven by pure electricity, and the engine is driven by fuel. The two cooperate with each other to form a variety of driving methods for hybrid ve...
