It should be noted that, in order to obtain the body surface temperature of the driver, an infrared temperature sensor may be installed in the vehicle, and the infrared temperature sensor may communicate with a controller (MCU) of the vehicle air conditioner, and obtain the body surface temperature of the driver through the infrared temperature sensor, and timely transmit detected data to the controller, and the controller compares the received body surface temperature of the driver with a first preset temperature prestored in the controller, so as to determine whether the vehicle air conditioner needs to be adjusted.
The technical solution of the present invention is explained in detail with reference to a specific embodiment.
As shown in fig. 2, the control method of the present invention includes: acquiring the body surface temperature T of a driver under the condition that the vehicle air conditioner operates in a refrigeration mode0(ii) a The body surface temperature T0And a first predetermined temperature T1Comparing; if the body surface temperature T0Less than a first predetermined temperature T1Adjusting the vehicle air conditioner; if the body surface temperature T0Not less than a first preset temperature T1The vehicle air conditioner is not adjusted. I.e. when the body surface temperature T of the driver0Less than a first predetermined temperature T1When the temperature of the body surface of the driver is low, the air conditioner for the vehicle needs to be adjusted, so that the situation that the driver is influenced by discomfort reactions such as local muscle spasm and the like possibly occurs is avoided; when the body surface temperature T of the driver0Is greater than or equal to a first preset temperature T1In time, it is said that the physical state of the driver is good, and the vehicle air conditioner may not be adjusted, so that the vehicle air conditioner may maintain the current state.
It should be noted that, in practical applications, a person skilled in the art may set a specific value of the first preset temperature according to experiments or experiences, as long as whether the body surface temperature of the driver is low can be determined by the critical point determined by the first preset temperature.
In addition, it should be noted that, when the vehicle air conditioner needs to be adjusted, the air output of the vehicle air conditioner may be reduced, or the control temperature of the vehicle air conditioner may also be increased, or the vehicle air conditioner may also be directly turned off, and so on.
Preferably, as shown in fig. 2, the step of "adjusting the vehicle air conditioner" specifically includes: if the first preset temperature T1Temperature T of body surface0Difference of (a ═ T)1-T0) Less than or equal to a first preset value A1Reducing the air output of the vehicle air conditioner; if the first preset temperature T1Temperature T of body surface0Is greater than a first predetermined value A1And is less than or equal to a second preset value A2Then the control temperature of the vehicle air conditioner is increased; if the first preset temperature T1Temperature T of body surface0Is greater than a second predetermined value A2If so, the vehicle air conditioner is closed; wherein the second preset value A2Greater than a first predetermined value A1。

Specifically, the invention passes the first preset value A1And a second preset value A2(A2＞A1) Three intervals are divided: the first interval is less than or equal to a first preset value A1(ii) a A second interval greater than the first preset value A1And is less than or equal to a second preset value A2(ii) a A third interval greater than a second preset value A2。
When the difference value deltaIn a first interval, i.e. the difference Delta is less than or equal to a first preset value A1When the temperature of the body surface of the driver is slightly lower, the body temperature of the driver can be relieved by reducing the air output of the vehicle air conditioner, and the body temperature of the driver is prevented from being continuously reduced. The air output of the vehicle air conditioner generally comprises four grades, the first grade is lowest, the air output is lowest, the fourth grade is highest and the air output is highest, at the moment, if the air output of the vehicle air conditioner is the third grade, the air output of the vehicle air conditioner can be adjusted to the second grade, namely, the air output of the vehicle air conditioner is reduced by one grade, so that the air output of the vehicle air conditioner is reduced, of course, the air output of the vehicle air conditioner can also be directly adjusted to the lowest grade, and the flexible adjustment and change do not deviate from the principle and the range of the invention and are limited within the protection range of the invention. Preferably, if the first preset temperature T1Temperature T of body surface0Is less than or equal to a first preset value A1And the air output of the vehicle air conditioner is the lowest grade, the control temperature of the vehicle air conditioner is improved. I.e. when the difference Δ is less than or equal to the first preset value A1In the meantime, if the air output of the vehicle air conditioner is the lowest level, the control temperature of the vehicle air conditioner can be increased. Through the arrangement, the invention is more intelligent and flexible.
When the difference Δ is in the second interval, i.e. the first preset value A1A difference value delta is less than or equal to a second preset value A2In this case, it is necessary to increase the control temperature of the vehicle air conditioner to relieve the body temperature of the driver so that the body temperature of the driver can be raised. For example, in this case, if the control temperature of the vehicle air conditioner is 22 degrees, the control temperature of the vehicle air conditioner may be adjusted to 23 degrees, that is, the control temperature of the vehicle air conditioner may be increased by one degree, or of course, the control temperature of the vehicle air conditioner may be increased by two or three degrees, and such flexible adjustment and change may be performed without departing from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
When the difference delta is in the third interval, i.e. the difference delta is larger than the second preset value A2When the temperature is lower, the body surface temperature of the driver is lower, at the moment, the air conditioner for the vehicle needs to be closed,so that the body surface temperature of the driver can rise.
It should be noted that, in practical applications, a person skilled in the art may flexibly set specific values of the first preset value and the second preset value according to experiments or experiences, as long as whether the body surface temperature of the driver is moderate and low can be determined by the critical point determined by the first preset value, and whether the body surface temperature of the driver is severe and low can be determined by the critical point determined by the second preset value.
Preferably, the control method of the present invention further comprises: continuously acquiring the body surface temperature T of the driver after the air conditioner for the vehicle is turned off0(ii) a When the body surface temperature T of the driver0Reaches a second preset temperature T2If so, restarting the vehicle air conditioner; wherein the second preset temperature T2Greater than a first predetermined temperature T1. That is, when the body surface temperature of the driver is severely low, the vehicle air conditioner is turned off first, and after the vehicle air conditioner is turned off, the body surface temperature of the driver slowly rises, and when the body surface temperature T of the driver is low0Exceeds a first preset temperature T1And reaches a second preset temperature T2When the physical state of the driver is recovered, the vehicle air conditioner can be restarted. Through the arrangement, the invention is more intelligent and humanized, and the user experience is better.
It should be noted that, in practical applications, a person skilled in the art may flexibly set the specific value of the second preset temperature according to experiments or experiences, as long as the critical point determined by the second preset temperature can determine whether the body state of the driver is suitable for restarting the vehicle air conditioner.
Finally, the invention also provides a vehicle comprising a controller (ECU) configured to be able to execute the control method described above.
