Torque sensor assembly applied to hybrid engine

Abstract

The invention discloses a torque sensor assembly applied to a hybrid engine and belongs to the field of hybrid engines. The torque sensor assembly applied to the hybrid engine comprises an engine andan ISG (integrated starter and generator) motor, the output end of the ISG motor is connected with a load, and a first connecting shaft between the engine and the ISG motor is provided with a first torque-angle collecting unit for collecting torque and rotating speed which are in real time output by the engine and transmitting the torque to the ISG motor; the ISG motor serves as an energy storageunit and is electrically driven to increase the rotating speed and the torque of the ISG motor to perform compensation on fluctuation of the torque in real time output by the engine; a second connecting shaft between the ISG motor and the load is provided with a second torque-angle collecting unit for collecting the torque and the rotating speed which are in real time output by the torque sensor assembly applied to the hybrid engine and taking the torque as feedback to correct control over the ISG motor and further compensate the fluctuation of the torque output by the torque sensor assembly applied to the hybrid engine.

Description

technical field [0001] The invention relates to the field of hybrid engines, in particular to a torque sensor assembly applied to hybrid engines. Background technique [0002] Hybrid systems are widely used, and more and more hybrid engines are used. The concept of the hybrid engine is to integrate a permanent magnet synchronous motor at the output end of the engine, so that it has the function of starting the engine / generating / driving. The advantage of the hybrid engine is that the starting torque is large, and the maximum torque can be output at 0 speed. The overall efficiency of the system is high, and the braking energy can be recovered. Shut down the engine, so save fuel. [0003] However, the disadvantages of the hybrid engine are also obvious. When it is frequently started and stopped, there is a vibration phenomenon, which affects the driving comfort. This is due to the structure of the engine. When the engine is working as a whole, the torque value of the engine ...

Problems solved by technology

However, the combustion in the cylinder of the engine is a process that is difficult to calculate accurately, so the error of the calculation result is often very large, so the calculated engine torque is difficult to use in actual control
