Research on the Constant Temperature Warm Clothing Based on DC Brush Less Motor Speed Control System

In cold regions such as Northeast China and Northwest China, the lowest temperature in winter can reach - 30°C. However, the Northeast China and Northwest China have a huge amount of fuel vehicles and a wide market potential for electric vehicles. The main reason hindering the promotion of electric vehicles in the above regions is the difficulty of using cars in winter. The purpose of this paper is to solve this problem, for the majority of owners to provide a constant temperature and warm solutions. The specific implementation method is: the carmen vortex street flow sensor is used to monitor the flow data, and the PT100 temperature sensor is used to detect the water temperature. The data are sent into the DC brush less motor speed control system based on DSP28335, and the flow data and temperature data are comprehensively judged to adjust the speed of the pump of the DC brush less motor. Thus, the thermostatic and warm clothes are provided to solve the problems of cold car start-up difficulty and battery life shrinkage in winter.
