and receiving positioning information, and acquiring the weather information and the road condition information in a specified range through the positioning information. The specified range is a range of a specified distance ahead of a traveling direction between a position where the vehicle is located and a destination.
In the driving process, the influence of weather and road conditions in front of the driving direction on the temperature and equipment of the vehicle is mainly used, therefore, positioning information needs to be positioned and received through a GPS or a Beidou navigation system, the position of the vehicle is judged, and then the weather information and the road condition information in a certain area range in front of the reverse direction of the vehicle between the current position of the vehicle and the destination are received, so that the influence of environmental information on the temperature and the equipment of the vehicle is analyzed, the adjusting result of an air conditioner is obtained, and the air conditioner is automatically adjusted. The specified area may be a distance range, for example, ten kilometers, twenty kilometers, etc., ahead of the vehicle in the traveling direction starting from the current position.
For special areas, for example, areas with high cold, high heat, strong wind or large changes in humidity, such as mountainous areas, basins, wind ports and deserts, which are entered from the front area, the air temperature and the climate can be pre-judged in advance and then the air conditioner can be correspondingly adjusted.
In addition, after receiving road condition information in a certain area range in front of the current position of the vehicle, for example, information which has great influence on equipment of the vehicle due to congestion, rugged road and the like, the air conditioner is correspondingly adjusted, damage to the equipment of the vehicle is reduced, and the service life is prolonged.
Further, the weather information includes climate change information and climate change information.
Temperature changes and climate changes can have certain influences on the temperature in the vehicle, and certain climate changes can also cause damage to vehicle equipment, for example, hail, sand wind, strong wind and the like can damage blades of an air conditioning fan.
Therefore, as shown in fig. 2, in step S200, the method further includes:
s210, obtaining the internal temperature TE of the vehicle at the current moment t i Acquiring an outside temperature TE of the vehicle based on the air temperature change information o ；
S220, judging TE o And TE i Obtaining the second temperature TE according to the difference Delta TE 2 ；
Wherein TE 2 ＝TE i ±TE α ；
TE α To a temperature compensation value, TE α ＞0。
When Δ TE > 0, the external temperature TE α Above internal temperature TE i . When Δ TE < 0, the external temperature TE α Below internal temperature TE i . In any case, in order to ensure the comfort of the interior of the vehicle, it is necessary to adjust the set temperature of the interior, that is, the temperature TE of the interior of the preceding vehicle i On the basis of increasing or decreasing a temperature compensation value TE α 。
Further, in step S220, the method further includes:
s221, judging whether the delta TE is larger than 0;
when Δ TE > 0, then TE 2 ＝TE i +TE α ；

When Δ TE > 0, and TE 2 ＞TE 1 When it is, the first set temperature TE of the air conditioner is maintained 1 ；
When TE 2 ＜TE 1 Then the air conditioner is set to the second set temperature TE 2 ；
When Δ TE < 0, and TE 2 ＞TE 1 Then the air conditioner is set to the second set temperature TE 2 ；

On the contrary, the second set temperature TE 2 If it is lower than the first set temperature TE 1 Adjusting the set temperature of the air conditioner to a second set temperature TE 2 。
Likewise, when the vehicle outside temperature TE o Below internal temperature TE i At the second set temperature TE 2 If it is lower than the first set temperature TE 1 Then the set temperature of the air conditioner is kept at the first set temperature TE 1 . On the contrary, the second set temperature TE 2 If it is higher than the first set temperature TE 1 Adjusting the set temperature of the air conditioner to a second set temperature TE 2 。
The adjustment can further ensure that the temperature in the vehicle is kept at a proper temperature, and ensure the comfort of passengers.
Further, the climate change information includes hail information.
As described above, a climate change, for example, hail, may damage equipment of the vehicle, and thus, the air conditioner needs to be adjusted in time when hail information is received.
Therefore, in step S200, the method further includes:
and S230, when the hail information is obtained, reducing the rotating speed of the external fan to the rotating speed of the first external fan, and increasing the rotating speed of the internal fan to the rotating speed of the first internal fan.
The impact force between the blades of the external fan and hailstones can be reduced by reducing the rotating speed of the external fan, and the blades of the fan are protected. After the rotating speed of the external fan is reduced, the comfort level of the temperature and the airflow inside the vehicle to passengers is influenced. Therefore, the rotation speed of the internal fan is increased, and the air flow circulation is increased.
Further, the traffic information includes road flatness information and traffic flow information.
As mentioned above, the road conditions also have an adverse effect on the vehicle equipment. The road surface roughness will produce jolt to the vehicle and the air conditioner will jolt with it. The air conditioner consumes a large amount of electricity, and when the electricity of the battery is low, the road condition of congestion is met, the rotating speed of the engine is low, the generated energy is small, the storage battery cannot be supplemented with a large amount of electricity, the fan needs to be adjusted, and the electricity is saved.
Therefore, in step S200, the method further includes:
s240, when the road flatness information exceeds the flatness threshold range, reducing the rotating speed of the internal fan of the air conditioner to the rotating speed of a second internal fan. And reducing the rotating speed of the external fan to the rotating speed of the second external fan. The compressor frequency is reduced to a first frequency.
And S250, when the electric quantity of the battery is lower than the designated percentage of the total capacity, adjusting the frequency of the compressor according to the traffic flow information.
And receiving the flatness information of the front road surface, comparing the flatness information with a pre-stored flatness threshold value, if the flatness information exceeds the threshold value range, considering the front road surface as a bumpy road surface, and predicting the range of the bumpy road surface. The rotating speed of the internal fan and the rotating speed of the external fan are reduced on a bumpy road surface, so that the vibration of the fans is reduced, and the service life of the air conditioner is prolonged. The second internal fan speed and the second external fan specification may be determined based on the received flatness information. While the frequency of the compressor is reduced, likewise, the first frequency may also be determined from the received flatness information.
Increasing the compressor frequency to the compressor frequency of the set temperature at a specified rate when traffic flow information is switched from the congested state to the smooth state.
The traffic flow is determined by the number of vehicles passing a certain point in a unit time. The number of vehicles passing a certain point in a unit time is set in advance as a standard value for judging the congestion state and the smooth state. When the vehicle flow is lower than the value, the state is considered to be in a congestion state, otherwise, the state is in a smooth state.
A large amount of power is consumed when the air conditioner is used. After the battery in the vehicle is fully charged in advance, the battery is discharged in various states and operations for air conditioning, lighting, and vehicle running during driving. However, when the engine is rotating at a high speed, the vehicle is driven to run, and power generation and charging of the battery are performed. However, in a congestion state, the engine speed is reduced, the power generation amount is greatly reduced, and the power consumption of the battery is much larger than the charge amount.
Further, the traffic information includes a congestion status and a smooth status. The congestion state is when the traffic flow is less than a specified traffic flow value. The smooth state is when the traffic flow is greater than a specified traffic flow value.
In step S200, the method further includes:
and S260, reducing the frequency of the compressor to a second frequency in the congestion state.
The second frequency may be determined based on the congestion status.
Further, in step S200, the method further includes:
and S261, when the traffic flow information is converted from the congestion state to the smooth state, increasing the compressor frequency to the compressor frequency of the set temperature at a specified rate.
When the vehicle gradually leaves the road section which enters the smooth state from the congestion state, the speed of the vehicle is gradually increased, the rotating speed of the engine is increased, the generated energy is increased, the storage battery can be charged, and at the moment, the frequency of the compressor can be increased to the normal state. However, when the frequency of the compressor is increased, the frequency cannot be directly increased from a low-frequency state to a high-frequency state, otherwise the compressor is damaged, and the service life of the compressor is shortened. Therefore, the compressor frequency is preferably raised at a rate of 1Hz/10 s.
According to the automatic adjusting method of the vehicle air conditioner, the environment information can be obtained through a mobile phone, a tablet personal computer, a vehicle-mounted terminal and the like, the air conditioner is controlled and adjusted through a vehicle-mounted controller, the external environment, the internal temperature and the information of vehicle-mounted equipment are obtained and judged, and the vehicle-mounted air conditioner is automatically adjusted.
