Problems solved by technology

[0002] In related technologies, the output torque of the motor on the vehicle is obtained through the calculation model of the motor torque controller, which is a calculated value. However, during the actual vehicle test process, the motor will be affected by the stiffness of the vehicle transmission system, the clearance of the transmission system, and the tires, etc. Due to the influence of influencing factors, the calculated motor output torque is not the actual output torque, and the frequency is low, which makes it difficult to reflect the fluctuation and impact of influencing factors on the motor output torque

Abstract

The invention discloses a motor shaft assembly, a motor assembly and a vehicle. The motor shaft assembly includes: a motor shaft, a detection part and a signal processing part, and the detection part is arranged on the outer surface of the motor shaft to be suitable for detecting The real-time torque of the motor shaft; the signal processing part is fixed to the motor shaft and connected to the detection part to obtain the real-time torque of the motor shaft. According to the motor shaft assembly of the present invention, by directly disposing the detection part on the outer surface of the motor shaft, the detection part can truly and accurately detect the real-time torque of the motor shaft, thereby improving the authenticity of detecting the torque of the motor shaft.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a motor shaft assembly, a motor assembly and a vehicle. Background technique [0002] In related technologies, the output torque of the motor on the vehicle is obtained through the calculation model of the motor torque controller, which is a calculated value. However, during the actual vehicle test process, the motor will be affected by the stiffness of the vehicle transmission system, the clearance of the transmission system, and the tires, etc. Due to the influence of influencing factors, the calculated output torque of the motor is not the actual output torque, and the frequency is low, which makes it difficult to reflect the fluctuation and impact of the influencing factors on the output torque of the motor. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present i...
