Research Of Parking Heater Control System

The area of north in winter is cold on our country, the temperature usually will be lower, the position of the parking lot is nervous, many cars will park in the outside, and outdoor temperature is usually a few degrees below zero in ten below zero to dozens of degree even. In such a low temperature conditions, a kick-off meeting for the vehicle is very difficult, and at the same time a kick-off meeting for low temperature to the use of cars have a great performance negative effects, or even influence in car heater service life, the appearance of low temperature cold start the car has had great harm the improvement in recent years, with people to ride comfort requirements continuously improved, and the application in the car heater is also becoming more and more widely in the low temperature environment, the car heater not only can fast start the car, and at the same time to the car heating, improve the inside temperature, which greatly improve the ride comfort.This topic is mainly to the car heater characteristics and basic theory in selected according to some basic parameters of the heater and technical indexes, and combined with the structure of the car features and choose the experiment with heater, establish the control model, to carry out experiments according to the experimental results, the choice single chip microcomputer control unit and sensor type, use the computer to control model established by the simulation analysis, the control system optimization, and select the parking heater to suitable for the development of auto.This topic research theory and simulation analysis by the method of combining the characteristics, and through the heater basic theory research, choose YJH-Q5/1heater as the research object, the original machine heating temperature control performance combustion emissions noise and control system, and other basic data analysis research, a deep understanding of the structure of the heater in car and use defect, so as to achieve use technical parameters, and use this as a new model research and development according to technical index, determine the choice of control devices and sensors, and set up the new control system model; second, using the software to establish control system model simulation analysis, and the car of the heater in car design system to control.
