And when the verification is passed, the user can be taken as a target user, and the position information of the user is obtained. When the position information of the target user is obtained, the position information of the target user can be obtained through a positioning function of mobile equipment carried by the target user, the position information can be understood as position coordinates of the target user, and then the relative distance between a vehicle and the target user is calculated according to the position information. For example, if the position information of the target user is obtained as (x, y, z), the position information of the vehicle is obtained as (x0，y0，z0) If so, a travelable path can be planned on the map according to the position information of the two, wherein the travelable path is the relative distance; the calculation mode of the relative distance can also be determined according to the environment of the target user, and if the target user and the vehicle are detected to be in the same open area, the relative distance can be directly calculated according to a distance formula between the two points.
Step S20: acquiring the current environment temperature, and determining a corresponding thermal management mode according to the current environment temperature;
in specific implementation, in order to implement intelligent vehicle thermal management, a current ambient temperature may be obtained, where the current ambient temperature includes, but is not limited to, an in-vehicle temperature, a power battery temperature of a vehicle, an engine temperature, and the like, and then a corresponding thermal management mode is matched in a preset mode library according to the current ambient temperature; and matching a corresponding thermal management mode in the preset mode library according to the current environment temperature and the relative distance, further obtaining a target distance difference between the relative distance and the preset distance, obtaining the current environment temperature, and matching the corresponding thermal management mode in the preset mode library according to the target distance difference and the current environment temperature. The preset pattern library stores various heat management patterns, and can be matched and selected according to temperature, distance and the like.

In this embodiment, position information of a target user is obtained, a relative distance between the target user and the target user is calculated according to the position information, a current ambient temperature is obtained, a corresponding thermal management mode is determined according to the current ambient temperature, and a vehicle heat pump system is controlled to perform thermal management according to the relative distance and the thermal management mode. The method comprises the steps of determining a corresponding heat management mode based on the obtained current environment temperature, obtaining position information of a target user, calculating a relative distance between a vehicle and the target user, controlling a vehicle heat pump system to carry out heat management according to the relative distance and the heat management mode so as to realize intelligent heat management of the vehicle, improving vehicle using experience of the user, and reducing unnecessary energy consumption by carrying out intelligent heat management on the vehicle based on the vehicle heat pump system.
Referring to fig. 3, fig. 3 is a schematic flow chart of a vehicle thermal management method according to a second embodiment of the invention.
Based on the first embodiment described above, in the present embodiment, the step S20 includes:
step S201: acquiring the current environment temperature and the temperature preference information of the target user, and calculating a target temperature difference according to the temperature preference information and the current environment temperature;
step S202: and determining a corresponding thermal management mode according to the target temperature difference.
In a specific implementation, in order to improve the intelligence degree of the heat management mode and further improve the intelligence degree of the heat management of the vehicle heat pump system controlled based on the heat management mode, can obtain the current environment temperature and the temperature preference information of the target user, and calculate the target temperature difference according to the temperature preference information and the current environment temperature, then determining a corresponding thermal management mode according to the target temperature difference, wherein the preset preference information comprises but is not limited to the preference temperature of the target user for the vehicle driving cabin, can be extracted from the user database of the preset application program, and provides data input by the user according to actual requirements, the modification can be carried out in real time, and correspondingly, the current temperature of the driving cabin can be extracted from the current ambient temperature, and then calculating the preference temperature of the target user for the vehicle cab and the current cab temperature to calculate the target temperature difference. Besides the temperature preference information, the system can also set the ordinary premises (such as the company position, the residence position and the like) and the routine outgoing time (such as the commuting time and the like), and then further optimize the selection of the thermal management mode according to the ordinary premises, the routine outgoing time and the like, such as the position of a user can be quickly determined according to the travelable path between the ordinary premises, and the judgment that the user enters the thermal management mode in advance according to the routine outgoing time of the user can be carried out.
It is easy to understand that after the target temperature difference between the temperature preference information and the current environment temperature is obtained, whether the target temperature difference is greater than or equal to a preset temperature difference or not can be judged, when the target temperature difference is greater than or equal to the preset temperature difference, a preset constant temperature mode is selected, and when the target temperature difference is less than the preset temperature difference, a preset heating mode is selected. The preset temperature difference can be set according to actual requirements, for example, 5 ℃, the preset constant temperature mode is used for performing constant temperature control on the vehicle so as to enable the vehicle to be maintained in a preset temperature range, the preset heating mode is used for performing heating control on the vehicle so as to enable the vehicle to be maintained in the preset temperature range after reaching the preset temperature, the preset temperature and the preset temperature range can be set according to the actual requirements, for example, the preset temperature can be set to 23 ℃, 24 ℃, 26 ℃ and the like, and the preset temperature range can be set to 21 ℃ -26 ℃ and the like.
In a specific implementation, in order to further improve the degree of intelligence when the thermal management mode is selected, a target distance difference between the relative distance and a preset distance can be obtained, then obtaining the current environment temperature, determining a corresponding thermal management mode according to the target distance difference and the current environment temperature, the preset distance may be set according to actual requirements, such as 100 meters, but this example is not limited thereto, for example, the heating time calculated according to the habitual speed of the target user is A, the heating power is B, and the target user speeds up halfway, so that the previous heating time is not enough to ensure that the driving cabin of the target user reaches the preset temperature when the target user reaches the driving cabin of the vehicle, a high-power heating mode may be selected when it is detected that the target distance difference is smaller than the preset distance difference, so as to ensure that the driving cabin reaches the preset temperature when the target user arrives at the driving cabin of the vehicle.
In the implementation, the current environment temperature and the temperature preference information of the target user are obtained, the target temperature difference is calculated according to the temperature preference information and the current environment temperature, and the corresponding heat management mode is determined according to the target temperature difference. The matching of the heat management modes is carried out by taking in factors such as the current environment temperature, the temperature preference information of the target user and the like, the intelligent degree of selecting the heat management modes is improved, and further, the intelligent degree of controlling the vehicle heat pump system to carry out heat management based on the heat management modes is also improved.

step S301: calculating heating time according to the target temperature difference and the relative distance, and calculating preheating time according to the heating time;
step S302: controlling a vehicle heat pump system to carry out heat management according to the heat management mode at the preheating moment;
it is easy to understand that after obtaining the target temperature difference between the current ambient temperature and the temperature preference information of the target user, the heating time may be calculated according to the target temperature difference and the relative distance, the preheating time may be calculated according to the heating time, and then the vehicle heat pump system is controlled at the preheating time according to the thermal management mode for thermal management, for example, if the heating speed of the vehicle heat pump system is X ℃/S, the target temperature difference is Y ℃, the heating time is (Y/X) S, the relative distance is S m, the habitual speed of the user is V m/S, the time that the user arrives at the vehicle cabin is about (S/V) m, the current time is T, the arrival time of the user is (T + S/V), the preheating time is (T + S/V-Y/X), and then the corresponding heating power P is queried in a preset power mapping table according to the relative distance, the preset power mapping table is a table storing a mapping relation between the relative distance and the heating power, namely, the vehicle heat pump system is controlled to carry out thermal management according to the thermal management mode at the moment of (T + S/V-Y/X) by the power P.
In another implementation manner of this embodiment, the step S30 includes:
step S303: and acquiring the preheating time set by the target user, and controlling a vehicle heat pump system to carry out heat management according to the heat management mode at the preheating time.
In a specific implementation, besides the preheating time obtained according to the calculation mode, the preheating time set by a user can be directly extracted from a user database of a preset application program, and the vehicle heat pump system is controlled to carry out heat management according to the heat management mode at the preheating time.
In the specific implementation, in order to further improve the vehicle using experience of the user, after the preheating time is obtained, the message pushing time and the corresponding pushing message are determined according to the preheating time, pushing the push message to a target user at the message pushing moment, wherein the message pushing moment can be a preheating moment, can also be a moment when a vehicle heat pump system is detected to be started, can also be a moment when the vehicle heat pump system finishes heating and enters constant temperature maintenance, correspondingly, the push message may be a message indicating that the vehicle heat pump system is heating, may be a message indicating that the vehicle heat pump system has been successfully started, may be a message indicating that the vehicle heat pump system has completed heating, in a specific implementation, both the message pushing time and the message pushing time may be set according to actual requirements, which is not limited in this embodiment.
