The invention discloses an anti-dry-burning control method for a film heater of a new energy automobile. Three water temperature sensors located at different positions are arranged in a film heater with a film heating plate, all the water temperature sensors are connected into the same control system, and the control system conducts dry burning fault diagnosis and conducts corresponding treatment according to diagnosis content through feedback signals of the three water temperature sensors. The invention has the advantages that: when the film heater is dry-burnt, the control system makes a judgment and cuts off the power of the high-voltage circuit of the heater according to the feedback signal of the water temperature sensor in the shortest time, so that the dry-burning of the film heater is effectively prevented, the dry-burning problem is solved from the control source of the heater, in addition, the detection and control modes are reasonable and effective, and the production efficiency is improved. Through specific processing of various detection information, information detection is accurate, the problem of false alarm caused by information detection errors is avoided, and the use reliability is greatly improved.

    本发明公开了一种新能源汽车膜加热器防干烧控制控制方法。通过在具有膜加热板的膜加热器内布置三个处于不同位置的水温传感器并将各个水温传感器连接到同一个控制系统内,通过三个所述水温传感器的反馈信号使控制系统做出干烧故障诊断并根据诊断内容进行相应处理。优点是:在膜加热器发生干烧时,在最短的时间内,通过水温传感器的反馈信号,控制系统做出判断,对加热器高压电路进行断电,从而有效地防止了膜加热器干烧,从加热器的控制源头解决了干烧问题,另外,其检测以及控制方式合理有效,通过对各种检测信息的特定处理使得信息检测准确,避免了信息检测错误导致的误报问题,大大提高了使用的可靠性。
