Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The reference numbers in the present application are only used for distinguishing the steps in the scheme and are not used for limiting the execution sequence of the steps, and the specific execution sequence is described in the specification.
In order to solve the problems in the prior art, embodiments of the present application provide a temperature control method applied to a vehicle, where an execution subject of the method may be a vehicle-mounted terminal. In the following, the present solution is described by taking an electric vehicle as an example, and it should be understood that the solution provided in the embodiment may also be used for adjusting the temperature of a non-electric vehicle. The scheme provided by the embodiment is shown in fig. 1a, and comprises the following steps:
s11: monitoring an interior temperature of a vehicle and an ambient temperature in which the vehicle is located, the interior temperature of the vehicle including a cabin temperature of the vehicle and a battery temperature of the vehicle.
In practical applications, monitoring of the interior temperature of the vehicle may be achieved by a temperature sensor disposed within the vehicle. For example, the cabin temperature may be monitored by a temperature sensor provided in the cabin, and the battery temperature of the vehicle may be measured by a temperature sensor provided in the vehicle battery.
In this step, the ambient temperature of the vehicle may be measured by a temperature sensor provided in the vehicle. If the vehicle has a network communication function, the weather information of the area where the vehicle is located can be obtained through the Internet, and the ambient temperature of the vehicle is further obtained.
In addition, for a vehicle parked at the roadside, the internal temperature of the vehicle and the environment in which the vehicle is located may be periodically detected. The vehicle energy consumption can be effectively reduced while the temperature of the vehicle is monitored.
S12: determining a safe temperature range according to the ambient temperature of the vehicle, wherein the safe temperature range comprises the ambient temperature of the vehicle.
In daily life, the high temperature of the vehicle caused by long-term exposure and the low temperature of the vehicle caused by freezing can cause damage to the vehicle and even shorten the service life of the vehicle components. In this step, the maximum value and the minimum value of the safe temperature range may be determined based on the ambient temperature in which the vehicle is located to determine the safe temperature range. For example, the safe temperature range is determined based on a preset temperature value of 5 ℃ and the ambient temperature. The result of the ambient temperature +5 ℃ was determined as the maximum value of the safe temperature range, and the result of the ambient temperature-5 ℃ was determined as the minimum value of the safe temperature range. In practical application, the preset temperature value for determining the safe temperature range can be preset according to actual requirements, or flexibly changed according to the situation of the position of the vehicle.
S13: and if the internal temperature of the vehicle exceeds a safe temperature range, sending a temperature control prompt to a mobile terminal associated with the vehicle.
In this step, it is determined whether the interior temperature of the vehicle is outside the safe temperature range. Since the safe temperature range is determined based on the temperature of the environment in which the vehicle is located, if the internal temperature of the vehicle exceeds the safe temperature range, the temperature in the vehicle may be too low relative to the temperature of the environment due to insolation by the sun, or the temperature in the vehicle may be too high relative to the temperature of the environment due to freezing or other reasons.
Taking summer as an example, the ambient temperature is 36 ℃ or 38 ℃, the vehicle is in a parking state, and the recorded temperatures are shown in the following table according to different temperatures in the vehicle or the battery.
According to the table, the temperature difference among the temperature in the vehicle, the temperature of the battery and the temperature of the environment where the vehicle is located is obvious under different environment temperatures. As the parking time of the vehicle increases, both the cabin temperature and the battery temperature in the vehicle increase. If the vehicle is exposed to the sun at a high ambient temperature, the temperature of the cabin and the battery in the vehicle will rise more rapidly.
If the internal temperature of the vehicle exceeds the safe temperature range for a long time, damage to vehicle components and even safety accidents may be caused. In this step, after the internal temperature of the vehicle exceeds the safe temperature range, a temperature control prompt is sent to the mobile terminal associated with the vehicle. The temperature control reminder may specifically include the monitored internal temperature and the safe temperature range of the vehicle, and may further include vehicle information, the internal temperature of the vehicle within a historical time period, and the like, so that a user holding the mobile terminal can perform processing according to actual needs.
The mobile terminal may be a mobile device such as a mobile phone, a tablet computer, and a notebook computer, or may be a wearable mobile device such as a smart watch. The mobile terminal can display the temperature control reminding to a user through the display screen, and can display the temperature control reminding through voice, indicator lights or other forms. The user can execute operation on the mobile terminal according to the temperature control prompt so as to feed back a control instruction to the vehicle-mounted terminal.
S14: and if a first temperature control instruction fed back by the mobile terminal based on the temperature control prompt is received, controlling the internal temperature of the vehicle according to the first temperature control instruction.
If the vehicle-mounted terminal receives the first temperature control instruction fed back by the mobile terminal, the analysis of the first temperature control instruction can be executed to determine the specific step of controlling the internal temperature of the vehicle. For example, when the internal temperature of the vehicle is too low, the first temperature control command may instruct the vehicle-mounted terminal to start functions such as air conditioning, warming, seat heating, and the like, so as to increase the internal temperature of the vehicle.
In addition, the first temperature control command may also include a period of time for which the interior temperature of the vehicle is controlled. For example, the air conditioner is started to heat for 10 minutes. Then, the vehicle-mounted terminal turns on the air conditioner to raise the temperature in the vehicle for ten minutes and then automatically turns off the air conditioner.
In practical applications, the in-vehicle terminal may control the interior temperature of the vehicle through various devices on the vehicle. In connection with the example below, a temperature management system applicable in a vehicle is described, as shown in fig. 1 b. The system comprises an electric compressor, a Condenser, a High Voltage Heater (HVH), an Air conditioning system (HVAC), a Chiller heat exchanger, a Battery pack water pump, a water valve and the like.
The water heater is used as a heat generating source for electric vehicle heat management, and can be used for providing a heat source for passenger compartment comfort in winter and a PACK (Battery PACK) temperature rise heat source at low temperature. The water pump is used for circulating the cooling liquid in the heat management pipeline, so that the cooling liquid heated by the water heater can be circulated in the pipeline. The three-way valve is connected among the HVAC, the water pump and the HVH, and can distribute part of high-temperature cooling liquid into a required cooling system according to a set proportion. The electric compressor can be used for providing air conditioner refrigerant power to realize refrigeration in the vehicle. The condenser may be used to cool a high pressure, high temperature refrigerant. The cooling fan may be used to dissipate heat from the electric drive system at high temperatures. The HVAC is used for the ventilation, cooling and heating functions of the air conditioning box.
When the vehicle is in a running or charging working condition, the monitored battery cell temperature or state can be received by a thermal management software module in the vehicle-mounted terminal, and if the battery temperature exceeds a safe temperature range, a pump valve and related components can be controlled to regulate and control the battery temperature in response to a first temperature control instruction of the mobile terminal.
The first temperature control instruction can be used for controlling the temperature, the air volume and the like in the vehicle. For example, the first temperature control command may be used to control the temperature of an air conditioner of the cockpit and the operation mode, which may be, for example, cooling, heating, automatic, etc. The air volume can be adjusted according to the temperature control requirement so as to control the temperature rising or reducing speed.
The first temperature control instruction can also adjust the air-conditioning outlet, for example, all the air-conditioning outlets are opened when the temperature needs to be adjusted quickly, and part of the air outlets are opened when the temperature needs to be adjusted slowly.
According to the scheme provided by the embodiment of the application, the temperature in the vehicle can be automatically monitored, and the remote control of the temperature is realized through communication with the mobile terminal. This scheme is particularly useful for electric automobile, can effectively prolong battery life, improves electric automobile security. In practical application, a user can send a first temperature control instruction through the mobile terminal according to actual requirements so as to control the vehicle-mounted terminal to execute required temperature control operation, and control of the temperature of the vehicle is achieved.
In practical application, after the user parks and leaves, the scheme provided by the embodiment can automatically monitor the temperature in the vehicle, and the user can adjust the temperature in the vehicle through the mobile terminal, so that the over-high or over-low temperature in the vehicle is avoided. Thus, the service life of each part of the vehicle can be prolonged, and the comfort of a user returning to the interior of the vehicle can be improved. The scheme is particularly suitable for the electric automobile, can effectively protect the battery of the electric automobile, prolongs the service life of the battery, and improves the safety of the vehicle parked under extreme weather.
Based on the solution provided in the foregoing embodiment, optionally, the lower limit value of the safe temperature range is a preset minimum safe temperature value, and the upper limit value of the safe temperature range is a sum of the ambient temperature and a preset safe difference value.
In this embodiment, the lower limit of the safe temperature range may be-15 ℃, the preset safe difference may be 8 ℃, and the upper limit of the safe temperature range may be +8 ℃. It should be understood that the preset safety difference may also be preset according to actual requirements, or may be flexibly adjusted based on historically collected temperature parameters.
Based on the solutions provided in the above embodiments, optionally, the safe temperature range includes a safe temperature range in the cabin and a safe temperature range of the battery.
In practical applications, the safe temperature range in the cabin and the safe temperature range of the battery may be different. In order to improve safety and extend the life of the battery, the safe temperature range of the battery may be smaller than the safe temperature range in the cabin. For example, the safe temperature range in the cockpit is-15 deg.C to ambient temperature +10 deg.C, and the safe temperature range of the battery is-15 deg.C to ambient temperature +8 deg.C.
As shown in fig. 2, the step S13 includes:
s21: and if the temperature in the cab of the vehicle exceeds the safe temperature range in the cab and/or the battery temperature of the vehicle exceeds the safe temperature range of the battery, generating a temperature control prompt according to the internal temperature exceeding the safe temperature range.
In practical applications, the temperature of the battery is usually different from the temperature of the cabin, since the battery is often not inside the cabin. In the step, whether the temperature in the cockpit exceeds the safe temperature range in the cockpit or not and whether the battery temperature of the vehicle exceeds the safe temperature range of the battery or not are respectively judged, and then the temperature control prompt is generated according to the internal temperature exceeding the safe temperature range.
S22: and sending the temperature control prompt to a mobile terminal associated with the vehicle.
The temperature control reminding in the step is generated according to the internal temperature exceeding the safe temperature range, and after the temperature control reminding is sent to the mobile terminal associated with the vehicle, the vehicle owner can know the temperature condition of the vehicle through the mobile terminal so as to generate a first temperature control instruction according to actual requirements and realize the temperature control of the interior of the vehicle.
Based on the solution provided by the foregoing embodiment, optionally, as shown in fig. 3, the foregoing step S21 includes:
s31: and generating a temperature control prompt containing candidate temperature control operation information, wherein the candidate temperature control operation information comprises information for controlling the operation of the internal temperature beyond the safe temperature range.
When the interior temperature of the vehicle is out of the safe temperature range, the interior temperature of the vehicle may be controlled by performing various operations. For example, for a vehicle parked in a sun exposure environment, the ambient temperature is often lower than the cabin temperature of the vehicle. The candidate temperature control operation information in the temperature control reminder generated at this time may include, for example, "air outside circulation in the vehicle", "air conditioning cooling in the vehicle". The owner can select the temperature control operation to be executed according to the requirement after receiving the temperature control prompt so as to generate a first temperature control instruction.
Specifically, because the battery capacity in the vehicle is limited, when the temperature in the vehicle is obviously higher than the ambient temperature of the vehicle, the external circulation of the air in the vehicle can be started only, and the low-temperature air in the environment outside the vehicle is used for cooling the cockpit in the vehicle. Therefore, the temperature control of the cockpit can be realized, and the electric consumption can be saved.
And if the temperature of the cab of the vehicle needs to be quickly reduced by the vehicle owner, the air conditioner in the vehicle can be selected for cooling. The temperature of the cabin can be rapidly reduced although more power needs to be consumed.
Wherein, the step S14 includes:
s32: and if a first temperature control instruction corresponding to the to-be-selected temperature control operation information and fed back by the mobile terminal based on the temperature control prompt is received, generating a second temperature control instruction according to the first temperature control instruction and the safe temperature range.
In this step, after receiving the first temperature control instruction, the first temperature control instruction is analyzed to determine the temperature control operation selected by the vehicle owner. And generating a corresponding second temperature control instruction according to the analyzed temperature control operation, wherein the second temperature control instruction is used for controlling a component or a system in the vehicle so as to perform temperature control on the interior of the vehicle.
S33: and controlling the internal temperature of the vehicle according to the second temperature control instruction.
Wherein the second temperature control instruction may include a plurality of sub-instructions that may be used to control different modules of the vehicle, respectively, to perform one or more temperature control operations selected by the user. For example, a first sub-command in the second temperature control command is used for controlling to start air-conditioning refrigeration, and a second sub-command is used for starting battery cooling.
Through the scheme provided by the embodiment, the vehicle-mounted terminal can provide various temperature control operations to be selected for the user, the user can select the required operation to execute temperature control according to actual requirements, and flexible control of the vehicle temperature is achieved.
Based on the solution provided by the foregoing embodiment, optionally, as shown in fig. 4, the foregoing step S31 includes:
s41: if the temperature in the cockpit of the vehicle is larger than the upper limit value of the safe temperature range in the cockpit, generating a temperature control prompt containing air conditioner cooling operation information;
s42: if the temperature in the cockpit of the vehicle is smaller than the lower limit value of the safe temperature range in the cockpit, generating a temperature control prompt containing air conditioner temperature rise operation information;
s43: if the battery temperature of the vehicle is greater than the upper limit value of the battery safety temperature range, generating a temperature control prompt containing battery cooling operation information, wherein the battery cooling operation information comprises information for controlling the operation of starting a battery cooler;
s44: and if the battery temperature of the vehicle is less than the lower limit value of the battery safety temperature range, generating a temperature control prompt containing battery heating operation information, wherein the battery heating operation information comprises information for controlling the operation of turning on the electric heater.
The present embodiment provides a variety of temperature control operations based on different situations. The air conditioner cooling operation can be recommended to be executed when the temperature of the cockpit is too high, the air conditioner heating operation can be recommended to be executed when the temperature of the cockpit is too low, the battery cooler can be recommended to be started when the temperature of the battery is too high, the electric heater can be recommended to be started when the temperature of the battery is too low, and the electric heater can be specifically a high-voltage electric heater.
The execution sequence of steps S41-S44 provided in this embodiment is not limited in this embodiment. In practical applications, one or more of the steps may be performed according to conditions that are actually met. Or, whether the execution requirements of the steps are met or not is sequentially judged, and the temperature control reminding is generated after the steps to be executed are determined.
According to the scheme provided by the embodiment of the application, the temperature of the vehicle cockpit and the temperature of the battery can be controlled effectively by executing the temperature control operation. And generating a temperature control prompt and sending the temperature control prompt to the mobile terminal, so that a feasible and effective temperature control suggestion can be provided for a user. After the user allows the operation or selects the operation to be performed, the in-vehicle terminal can perform the temperature control operation based on the feedback of the user.
Based on the solutions provided by the above embodiments, optionally, as shown in fig. 5, the first temperature control instruction includes a confirmation instruction for at least one item of candidate temperature control operation information.
In practical application, the mobile terminal can display various temperature control operations in the to-be-selected temperature control operation information in a virtual key mode. The user can select the temperature control operation to be executed by clicking or other forms, and the mobile terminal can generate a confirmation instruction according to the selection result of the user. The confirmation instruction corresponds to at least one temperature control operation selected by the user.
Wherein, the step S32 includes:
s51: and generating the second temperature control instruction according to the confirmation instruction and the safe temperature range, wherein the second temperature control instruction comprises a temperature control operation corresponding to the confirmation instruction and an operation stop rule corresponding to the safe temperature range.
In this step, the in-vehicle terminal may determine, according to the confirmation instruction fed back by the mobile terminal, which temperature control operations are to be performed, and determine an operation stop rule when to stop the temperature control operations according to the safe temperature range.
For example, it is determined that the air conditioning warming is to be turned on according to the confirmation instruction, and it is determined that the air conditioning warming is to be stopped when the cabin reaches 18 ℃ according to the safe temperature range.
In practical application, the scheme provided by the embodiment can execute the temperature control operation selected by the user, and realize the control of the vehicle temperature. And when the temperature control operation is finished is determined according to the safe temperature range, so that resource waste is avoided for colleagues realizing the in-vehicle temperature control.
Wherein, the step S33 includes:
s52: and controlling the vehicle to execute the temperature control operation corresponding to the confirmation instruction.
For example, the in-vehicle terminal controls the vehicle to perform an air-conditioning warming operation to raise the temperature of the cabin of the vehicle.
S53: and when the vehicle conforms to the operation stop rule, stopping executing the temperature control operation corresponding to the confirmation instruction.
For example, the operation stop rule determined according to the safe temperature range is: the cabin temperature reached 18 c and was stopped. Then, when the temperature sensor detects that the temperature of the cabin of the vehicle reaches 18 ℃, the control stops the air-conditioning heating of the vehicle.
The scheme provided by the embodiment can realize remote temperature control, and the vehicle-mounted terminal can execute the temperature control operation remotely selected by a user to realize in-vehicle temperature control. And moreover, the time for stopping the temperature control operation can be determined according to the safe temperature range, so that the resource waste is avoided.
Based on the solutions provided by the above embodiments, optionally, the operation stop rule includes at least one of the following:
the interior temperature of the vehicle is within the safe temperature range;
the time length for executing the temperature control operation corresponding to the confirmation instruction is greater than or equal to the preset execution time length;
and the resource amount remained after the temperature control operation corresponding to the confirmation instruction is executed in the vehicle is lower than the preset resource amount.
In practical applications, it is possible to determine when to stop the temperature control operation based on not only the safe temperature range but also the length of time for which the temperature control operation is performed and the resources stored in the vehicle.
If the vehicle performs the temperature control operation for an excessively long period of time, there is a possibility that the temperature control operation performed cannot effectively control the temperature, or that an abnormality occurs in a vehicle component. At this time, the temperature control operation may be stopped, the temperature control operation to be selected may be re-determined according to the monitored temperature, and the temperature control operation may be re-executed according to the feedback of the mobile terminal.
The in-vehicle terminal tends to consume resources stored in the vehicle when performing the temperature control operation. For electric vehicles, temperature control operations often consume the amount of power stored by the vehicle's battery, and the vehicle cannot be started if the battery power is depleted. In order to ensure the normal starting of the vehicle, the resource amount can be preset so as to avoid the condition that the power storage amount of the vehicle is insufficient due to the temperature control operation. For example, the preset resource amount is 40%, and if the remaining electric quantity of the vehicle-mounted battery is lower than 40% after the temperature control operation is executed, the temperature control operation is stopped, and the influence of insufficient power storage of the vehicle on normal starting is avoided.
Referring to fig. 6, the present solution is described below with reference to an example. In the embodiment, under the working conditions of high temperature and low temperature (the environment temperature is less than or equal to-15 ℃ or more than or equal to 35 ℃), after the vehicle is stopped and flamed out, the temperatures of a cockpit and a battery in the vehicle are periodically wakened up and collected, and if the temperature exceeds a safe temperature range, the vehicle owner is reminded through cloud pushing to select whether to execute temperature control operation.
In practical application, the difference between the ambient temperature in summer and the ambient temperature in winter is large, when the temperature difference between the interior and the exterior of the automobile is larger than or equal to 10 ℃ under the working condition of summer (the temperature outside the automobile is larger than 35 ℃), the cloud end pushes the overhigh temperature in the automobile to the client through the mobile phone APP, the client is reminded to start the air conditioner for cooling, and the client selects whether to start the air conditioner or not. When the temperature of the battery is higher than the temperature outside the vehicle by 8 ℃, the cloud reminds the client of exceeding the standard of the temperature of the battery through pushing of the mobile phone APP, and the client selects whether to start the compressor to cool the battery.
Under the working condition in winter (the temperature outside the automobile is less than-15 ℃), when the temperature inside the automobile is less than-15 ℃, the cloud end pushes the temperature inside the automobile to exceed the standard through the mobile phone APP, and reminds the client to start the air-conditioning heating. Similarly, the temperature of the battery is pushed to remind the client to start the heating battery.
The scheme that this embodiment provided through in-car temperature and battery electric core temperature under the different ambient temperature of monitoring when flameout parking, initiatively reminds the user to carry out in-car temperature control when surpassing safe temperature range, promotes driver and crew's travelling comfort, and extension battery life and reinforcing high low temperature battery power improve whole car continuation of the journey.
