Abstract

The invention discloses a hybrid power system for an automobile. The hybrid power system comprises an engine, a power battery, an electric energy manager electrically connected with the power battery, a first motor connected with the engine and electrically connected with the electric energy manager, a second motor electrically connected with the electric energy manager and connected to a rear drive axle through a single-stage speed reducer, a speed changer connected to the first motor through a main clutch, a planetary gear and a controller, wherein a planetary carrier of the planetary gear is connected with an output shaft of the speed changer, a gear ring of the planetary gear is connected to a front drive axle through a front clutch, a sun wheel of the planetary gear is connected to the second motor through a rear clutch, and the controller controls at least one of a group composed of the engine, the power battery, the first motor and the second motor to drive the whole automobile under the different working conditions of the automobile. The working conditions of the automobile include speed, SOC and load of the automobile. The invention further provides a hybrid power vehicle and a control method thereof.

Description

technical field [0001] The invention belongs to the technical field of power control for vehicles, and in particular relates to a hybrid power system for automobiles, a hybrid power vehicle and a control method thereof. Background technique [0002] The working modes of new energy electric vehicles are mainly divided into series mode, parallel mode and pure electric mode. In the series mode, since the engine speed is not restricted by the vehicle speed, the optimization flexibility of the engine is great, and the theoretical fuel saving rate is high. However, since the series mode is driven by the motor alone, the power performance is poor. In parallel mode, the speed of the engine is constrained by the vehicle speed, and the theoretical economy is poor, especially at low speed and low load, the optimization of the engine is very limited; in parallel mode, the torque of the engine can be coupled with the torque of the motor. When driving, it is often limited by adhesion. T...
