Problems solved by technology

The existing technology cannot drive the vehicle in pure electric mode, and the engine still needs to be used to start the vehicle, the engine is in a low-efficiency zone, and the method of controlling the vehicle start by combining the clutch makes the vehicle start less comfortable
The existing technology still uses the traditional AMT gearbox, generally a five-speed gearbox, the gearbox is large in size and high in cost
When shifting gears, it is necessary to disengage and engage. Only after the input torque is cleared can the gear be removed and selected. During this process, the power of the vehicle will be interrupted.

Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] refer to figure 1 , a hybrid power system with BSG and drive motor on the output shaft of the gearbox, which is composed of BSG motor 1, ICE2, clutch 3, gearbox 4, drive motor 5 and front drive shaft 6 connected in sequence, and the drive motor 5 is connected through gears and The output shaft of the gearbox 4 is connected with a fixed speed ratio. The BSG motor 1 is arranged at the front end of the engine and connected with the engine by a belt.

[0025] The gearbox 4 is a three-speed gearbox, which is provided with three gear positions: forward gear, neutral gear, and reverse gear.

[0026] A control method for a hybrid power system in which a BSG and a drive motor are on an output shaft of a gearbox, the specific control process is as follows:

[0027] Step 1. Pure electric mode: When the required drive torque is l...

Abstract

The invention discloses a hybrid power system with a BSG and a drive motor arranged on an output shaft of a gearbox and a control method thereof. The system is formed by sequentially connecting the BSG, an ICE, a clutch, the gearbox, the drive motor and a front drive shaft, wherein the drive motor is connected to the output shaft of the gearbox through a gear and has a fixed speed ratio, and the BSG is arranged at the front end of an engine and is connected to the engine through a belt. The invention further discloses the control method of the hybrid power system with the BSG and the drive motor arranged on the output shaft of the gearbox. According to the hybrid power system with the BSG and the drive motor arranged on the output shaft of the gearbox and the control method thereof, the drive motor directly drives the output shaft of the gearbox to rotate through the gear and drives a vehicle to travel; the motor has low speed and large torque, and the efficiency of the motor is obviously higher than the efficiency of the engine at low speed.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and relates to a hybrid power system with a BSG and a drive motor on the output shaft of a gearbox and a control method thereof. Background technique [0002] When a traditionally powered vehicle is waiting for a red light or in a traffic jam, if the driver does not actively turn off the engine, the idling of the engine will increase fuel consumption, resulting in serious energy waste and environmental pollution. The existing BSG hybrid system adds a BSG motor to the traditional car. The BSG motor is arranged at the front end of the engine, and the start of the engine is controlled by the belt to realize the start and stop control of the engine. However, the existing BSG system only realizes the start-stop control function of the engine, which is a weak hybrid technology. When the vehicle starts, it still relies on the clutch to combine with the engine to start, and the engine stil...
