Title:
HYBRID POWER DRIVING APPARATUS FOR HYBRID ELECTRIC VEHICLE, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/226660
Kind Code:
A1
Abstract:
Provided are a hybrid power driving apparatus for a hybrid electric vehicle, and a control method therefor. The hybrid power driving apparatus comprises an engine (1), an auxiliary electric motor assembly (2), a main driving electric motor assembly (3), an output shaft (4) and a differential assembly (5), wherein the auxiliary electric motor assembly (2) is connected to the engine (1), and the engine (1) and the main driving electric motor assembly (3) are connected to the differential assembly (5) by means of the output shaft (4). Switching between output working modes is realized by means of cooperation between the engine (1), the auxiliary electric motor assembly (2) and the main driving electric motor assembly (3); in addition, according to working state information of the assemblies of the hybrid power driving apparatus, intention information of a driver, and operation condition information of a vehicle, an output working mode is allowed to have two gear changes by means of a gear shifting actuation apparatus (6), such that the adaptability of the whole hybrid power driving apparatus to different working conditions is improved, the fuel consumption of the whole vehicle is reduced, the smoothness of driving and driving comfort are improved, and the hidden danger of power interruption of the hybrid power driving apparatus during a gear shifting process is prevented.
