The engine warming speed is accelerated, the fuel consumption and the pollutant emission of the automobile are reduced, and heat required by warm air can be supplied to a driver and passengers earlier. Some automobiles close the warm air water circulation by setting an electromagnetic valve on a warm air water path and closing the electromagnetic valve so as to accelerate the warming-up speed of the engine.
However, in the prior art, when the warm air is required, the opening and closing of the warm air water circulation is controlled according to the water temperature of the engine, the change of the external temperature is not considered, and the requirement and the feeling of a user are not considered. If the set engine water temperature threshold is too large, the time for the engine water temperature to reach the threshold is too long when the weather is particularly cold, which is easy to cause complaints of users. If the set water temperature threshold of the engine is too small, when the weather is not very cold, warm air water circulation is started if the engine is not fully warmed, and quick warming is not facilitated.
In addition, in the prior art, when no warm air is required, no warm air water circulation is opened no matter how much the water temperature of the engine is. It fails to utilize the heat dissipation of the warm air water path, requiring a radiator and fan of greater heat dissipation capacity, increasing the cost of the engine cooling system.

Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the present invention has an electromagnetic valve disposed on the warm air water path, the electromagnetic valve controls the opening and closing of the warm air water circulation, the electromagnetic valve is controlled by a controller, and the controller determines whether to close the electromagnetic valve according to the ambient temperature, the engine water temperature, the engine operating state, and the warm air request state. When the electromagnetic valve is not electrified, the electromagnetic valve is in an open state, and the warm air water is circularly opened; when current flows through the electromagnetic valve, the electromagnetic valve is closed, and the warm air water circulation is closed. For the sake of functional safety and energy conservation, the solenoid valve is of a normal type.
As shown in fig. 2, in order to control the warm air water circulation according to the present invention, the operation state of the engine is first detected, and when the engine is not operating, the solenoid valve on the warm air water path is not energized, and the warm air water circulation remains open.
When the engine runs, whether a warm air demand exists is detected, whether an electromagnetic valve on a warm air water path is started is judged according to the magnitude relation between the running time of the engine, the water temperature of the engine and preset values, and whether warm air water circulation is started is determined, wherein the preset values comprise a set time value T1, a first temperature threshold value T1 and a second temperature threshold value T2, and the set time value, the first temperature threshold value and the second temperature threshold value are all calibrated values, specifically as follows.
If the air conditioning system has a warm air demand, when the engine operation time is less than or equal to a set time value T1 and the engine water temperature is less than or equal to a first temperature threshold value T1, the warm air water circulation is closed to accelerate the warming-up of the engine. Otherwise, when the running time of the engine is greater than the set time value T1 or the water temperature of the engine is greater than the first temperature threshold value T1, the warm air water circulation is opened, and heat required by warm air is provided while heat dissipation is assisted.
If the air conditioning system has no warm air demand, when the temperature of the engine water is less than or equal to a second temperature threshold T2, the warm air water circulation is closed to accelerate the engine warm-up. Otherwise, when the temperature of the water in the engine is greater than a second temperature threshold T2, a warm air water circulation is opened to assist the engine in dissipating heat.
The set time value t1 for the engine operation is obtained from a MAP1 that looks up the vehicle exterior ambient temperature. The MAP1 is set according to the time for waiting for warm air that is acceptable to users in different regions obtained by market research. Acquiring the warm air waiting time acceptable by users in different regions (which can be divided based on the average temperature in winter) in the historical record to obtain an original data set; randomly extracting N sample data from original data sets of different regions in a random sampling mode; and removing a maximum value and a minimum value in the sample data extracted from each region, calculating an average value of the residual sample data, and obtaining the warm air time of different regions, thereby obtaining set time values t1 corresponding to different environmental temperatures.
The first temperature threshold T1 of the engine water temperature is obtained according to an engine friction work test, and engine water temperature and engine friction work data are obtained; and calculating the friction work change of the unit water temperature change according to the acquired data, and taking the water temperature corresponding to the node smaller than the preset change as the engine water temperature threshold T1. The second temperature threshold T2 is determined based on the actual heat dissipation requirements of the engine, and is generally within the normal operating temperature range of the engine or slightly less than the minimum value of the normal operating temperature of the engine, where T1 is less than T2.
