Abstract

The invention relates to the technical field of automobile assembly and discloses a method, a device, a device and a system for calibrating an initial angle of a motor resolver. The method comprises the following steps: acquiring a vehicle ID of a vehicle to be calibrated and acquiring an actual resolver initial angle value corresponding to the vehicle ID from a vehicle information database storedin advance; A write command is sent to the motor controller of the vehicle to be calibrated, the write command including the actual resolver initial angle value to cause the motor controller to modify the resolver initial angle value in the motor controller built-in program to the actual resolver initial angle value. The technical proposal provided by the embodiment of the invention eliminates the risk of human error caused by human operation through the automatic writing mode, and simultaneously improves the calibration efficiency of the initial angle of the resolver.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to a method, device, equipment and system for calibrating the initial angle of a motor resolver. Background technique [0002] The electric vehicle is driven by a permanent magnet synchronous motor. The permanent magnet synchronous motor analyzes the rotor position through the resolver. The motor controller calculates the accurate magnetic pole position of the rotor by decoding the rotor position and the initial angle value of the resolver, and then realizes the permanent magnet synchronous motor. closed-loop accurate control. Among them, the initial angle of the resolver is the deviation angle between the zero angle of the resolver and the zero angle of the permanent magnet synchronous motor, also called the initial zero angle of the motor, which is usually determined after the resolver is installed. [0003] When the vehicle is off the assembly line, it is necessary t...
