Problems solved by technology

The above-mentioned hybrid power device has the following problems: in the pure electric driving mode, since the ISG motor is fixedly connected to the engine crankshaft and does not move, only the driving motor drives the vehicle, so that the power of the driving motor must be relatively large to meet the performance of pure electric driving indicators, resulting in higher cost of the device; in the hybrid driving mode, power interruption is unavoidable when shifting gears, and the shifting performance is reduced; two clutches and a shifting synchronizer are used, and the shifting mechanism is more complicated, resulting in high installation cost

Abstract

The invention relates to a hybrid power device. The hybrid power device comprises an engine, a main clutch, a first motor, a second motor, a first speed change mechanism, a second speed change mechanism, a first main speed reducer driving gear, a second main speed reducer driving gear and a main speed reducer driven gear, wherein the engine drives the first main speed reducer driving gear and the main speed reducer driven gear through the main clutch and the first speed change mechanism; the first motor drives the first main speed reducer driving gear and the main speed reducer driven gear through the first speed change mechanism; and the second motor drives the second main speed reducer driving gear and the main speed reducer driven gear through the second speed change mechanism. According to the hybrid power device, on a pure electric driving mode, the two motors can drive a vehicle jointly after the main clutch is separated, so that the power and cost of the second motor are reduced; and in the hybrid power driving mode, the two speed change mechanisms can be shifted one after another, power interruption is avoided, and thus the gear-shifting performance is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle driving, in particular to the field of electric vehicle hybrid driving, and specifically refers to a hybrid power device and a control method thereof. Background technique [0002] The hybrid power device disclosed in the prior art includes: an engine, an ISG motor fixedly connected to the crankshaft of the engine, a drive motor, a two-speed transmission and two clutches, one of which is arranged between the drive motor and the input end of the two-speed transmission, and the other A clutch is disposed between the ISG electric motor and the input of the two-speed transmission. The above-mentioned hybrid power device has the following problems: in the pure electric driving mode, since the ISG motor is fixedly connected to the engine crankshaft and does not move, only the driving motor drives the vehicle, so that the power of the driving motor must be relatively large to meet the performance...
