Abstract

The invention discloses a networked measurement and control method for the functional matching control of the driving motor working conditions of an electric vehicle, which simulates the driving path and sets the operating conditions, adopts an AC-DC-AC power conversion circuit and a SVPWM working condition matching control method, and constructs a A drive motor closed-loop system with constant power and constant torque output under variable working conditions is used to simulate the overall dynamic performance of electric vehicles during the actual operation process. Using multi-sensor fusion and network technology, the drive system, load simulation system, Collect and process key information such as electrical, mechanical, and interference in the operation of the power system, and establish curve models such as power, efficiency, speed, and mechanical characteristics, and comprehensively analyze the dynamic performance of the drive system under different working conditions, and based on CAN The network form of the bus, the comprehensive evaluation of the system performance on the host computer, plays a positive role in improving the performance of the motor, the performance of the drive system and the improvement of the control strategy.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a networked measurement and control method for working condition matching control of an electric vehicle drive motor. Background technique [0002] An electric vehicle is an electric drive vehicle, also known as an electric drive vehicle. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as the energy source, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. Contents of the invention [0003] The purpose of the present invention is to provide a networked measurement and control method for the matching control of the driving motor working conditions of electric vehicles, aiming to solve the problem of instability and insufficient accuracy in controlling the speed ...
