Problems solved by technology

However, when the ambient temperature is low or the number of occupants is large, the front windshield will have a greater risk of fogging, which will affect the driver's driving and pose a greater safety hazard
The current method of car defogging is basically manual operation, that is, when the driver finds that the front shield is foggy, manually set the air conditioner to the defrosting and defogging mode. At this time, the compressor is turned on, the air volume of the blower is adjusted to the maximum, and the air intake mode is adjusted to external circulation. For defogging, although this method can achieve the purpose of defogging, it needs to be manually operated, and the working mode is not smart enough, without considering the weather conditions and air conditioning energy saving

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0048] Such as figure 1 As shown, this embodiment provides a control method for automatic defogging of automobiles, which is applied to an automatic defogging control system for automobiles. Acquisition module, outside temperature sensor, sunshine sensor, evaporator temperature sensor and rainfall acquisition module, thermal management controller and obtain vehicle speed, engine water temperature and other signals through vehicle CAN as control signal input. Control methods specifically include:

[0049] The thermal management controller confirms whether the power-on state of the vehicle is ON;

[0050] If so, the thermal management controller collects the air temperature, air humidity, outside temperature and sunshine intensity in the car in real time through the sensor;

[0051] The thermal mana...

Abstract

The invention relates to a control method for automatic demisting of an automobile and the automobile, which are applied to an automatic demisting system. The system comprises a thermal management controller, an in-automobile temperature and humidity acquisition module, an out-automobile temperature sensor, a sunlight sensor, an evaporator temperature sensor and a rainfall acquisition module, signals such as the vehicle speed and the engine water temperature are obtained through the whole vehicle CAN to serve as control signal input. The method comprises the steps that when the power-on stateof the automobile is ON, the temperature in the automobile, the humidity in the automobile, the temperature outside the automobile and the sunlight intensity are collected in real time to calculate the front windshield fogging probability; the air conditioner requirement of the user is acquired by obtaining the air conditioner setting of the user; vehicle speed, rainfall, engine water temperatureand evaporator air outlet temperature signals are collected as input of the controller to be used for correcting control parameters; and according to the parameters such as the front gear fogging probability, the air conditioner requirement of the user and the vehicle speed, the temperature air door opening degree, the air outlet mode, the air blower gear, the air inlet mode and the compressor state are controlled for automatic defogging, manual operation is reduced, and driving safety is improved.

Description

technical field [0001] The invention belongs to the field of automobile air conditioners, and in particular relates to a control method for automatic defogging of automobiles and the automobile. Background technique [0002] The front windshield of the car is used for the driver to observe the road ahead, which is very important to driving safety. However, when the ambient temperature is low or the number of occupants is large, the front windshield will have a greater risk of fogging, thereby affecting the driver's driving and posing a greater safety hazard. The current method of car defogging is basically manual operation, that is, when the driver finds that the front shield is foggy, manually set the air conditioner to the defrosting and defogging mode. At this time, the compressor is turned on, the air volume of the blower is adjusted to the maximum, and the air intake mode is adjusted to external circulation. For defogging, although this method can achieve the purpose o...
