Abstract

The invention discloses a hybrid power system for automobiles, comprising: an engine, which drives the front drive axle of the automobile through a transmission, and the transmission is connected to the engine through a clutch; an auxiliary motor, which is connected in parallel with two shafts of the engine; a rear drive motor, The rear drive motor is used to drive the rear drive axle of the car; the energy storage device, which is electrically connected to the auxiliary motor and the rear drive motor respectively; and the controller, which controls the rear drive motor to drive the rear drive axle when the car shifts gears . The hybrid power system controls the rear drive motor to drive the vehicle through the controller when the car shifts gears, avoiding the power interruption of the car when the car shifts gears, thereby ensuring the smoothness of the vehicle's driving and improving the average speed during driving. The invention also provides a hybrid electric vehicle and a control method thereof.

Description

Technical field [0001] The invention belongs to the technical field of vehicle power control, and in particular relates to a hybrid power system for an automobile, a hybrid vehicle and a control method thereof. Background technique [0002] Such as figure 1 As shown, the existing hybrid power system for automobiles includes an engine 1', a clutch 2', a transmission 3', an auxiliary motor 4', and an energy storage device 5'. Among them, the auxiliary motor 4'is connected to the energy storage device 5', the engine 1'is connected to the input shaft of the gearbox 3'through the clutch 2', and the input shaft of the gearbox 3'is connected to the output shaft of the auxiliary motor 4', so that the engine The power of 1'and the auxiliary motor 4'are both outputted by the output shaft of the oil transmission 3', and the wheels 6'are driven forward. In the process of changing the hybrid power system, there will be a period of power interruption, which will affect the continuity of the h...
