Motor rotor positioning system for hybrid vehicle and positioning method thereof

Abstract

The invention aims to provide a motor rotor positioning system for a hybrid vehicle and a positioning method thereof, which are suitable for the characteristics of a vehicle production line. The positioning system consists of a detection unit and a calibration unit, wherein the detection unit comprises a power device capable of driving a motor to be positioned to rotate, a detection host computer, a bar code scanner, a zero crossing detection device and a motor rotor position sensor arranged on the motor to be positioned, and the detection host computer is connected with the power device, the bar code scanner, the zero crossing detection device and the motor rotor position sensor; the calibration unit comprises a bar code scanner and a calibration host computer, and the calibration host computer is connected with a motor controller of the motor to be positioned; and the detection host computer and the calibration host computer are connected with a database server through a network respectively. The detection host computer detects the position angle value of the motor rotor through the zero crossing detection device and the motor rotor position sensor, transmits the position angle value to the calibration host computer, and further writes the position angle value into the motor controller so as to finish the positioning of the motor rotor.
