Description

Technical Field

[0001] This invention belongs to the field of intelligent vehicle technology, specifically, it relates to a remote start system for automotive air conditioning. Background Technology

[0002] Remote start of car air conditioning refers to the ability to remotely activate the car's air conditioning system to cool or heat the vehicle before the user enters it, ensuring a comfortable driving temperature environment upon entry without requiring a long wait. This convenience and comfort greatly enhance the user's driving experience.

[0003] In existing technologies, remote start systems for car air conditioning establish a communication connection between a mobile phone and the vehicle. A period of time before the vehicle is needed, the user starts the car air conditioning via a terminal device to adjust the temperature. This presents the following problems: after being turned on, the air conditioning operates using inverter technology based on the interior temperature to quickly reach the preset temperature; each time the air conditioning is remotely started, the user needs to estimate the time; and if the owner does not enter the vehicle for an extended period after the remote start, energy is wasted, or the interior temperature may not have reached the preset value when the owner enters the vehicle, thus affecting the user experience. To solve these problems, this invention provides the following technical solution. Summary of the Invention

[0004] The purpose of this invention is to provide a remote start system for automotive air conditioning, which solves the problems of energy waste and the fact that the interior temperature does not reach the preset value when the user enters the vehicle in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The car air conditioning remote start system includes:

[0007] Temperature detection module, used to detect the temperature inside and outside the vehicle;

[0008] The temperature control module is used to adjust the operating temperature and fan speed of the vehicle's air conditioning system.

[0009] The communication module is used to establish a communication connection with the terminal device;

[0010] The working method of the above-mentioned remote start system for automotive air conditioning includes the following steps:

[0011] The first step is to obtain the high-frequency usage time periods of the car owner within a certain period of time. The high-frequency usage time periods refer to the concentrated time points when the car owner starts the vehicle within a certain period of time.

[0012] The second step is for the temperature detection module to obtain the in-vehicle temperature Tn and the outside temperature Tw. Based on the in-vehicle temperature Tn and the outside temperature Tw at this time, the real-time balance duration T is obtained. When the time difference between this time and the start point of the high-frequency vehicle use period is T+ty1, the communication module sends a prompt to the corresponding terminal device to remind the user to remotely start the air conditioner or make a remote start reservation. ty1 is a preset value.

[0013] The third step involves remotely starting the car's air conditioning to heat or cool the interior; this includes the following steps:

[0014] The terminal device establishes a connection with the communication module, and sends control information for remote start of the air conditioner to the communication module.

[0015] If the air conditioner is required to be turned on at the current moment, the air conditioner will be turned on immediately and will cool or heat at the preset power.

[0016] If the air conditioning is scheduled to turn on at a future time, the real-time interior temperature and the real-time exterior temperature are obtained, and then the balance time T is obtained. If T is greater than t1, the air conditioning will operate in inverter mode to increase the cooling and heating power. If T is less than or equal to t1, the air conditioning will start to cool or heat at the preset power until t1 = T + ty, where ty is a preset value greater than or equal to 0, and t1 is the time from the current time to the scheduled time.

[0017] The equilibrium time T refers to the time it takes for the car's interior to reach a temperature equilibrium state after the car's air conditioner cools or heats at a preset power. The temperature equilibrium state means that the temperature inside the car changes within a preset time t2, which is less than a preset value T1.

[0018] As a further aspect of the present invention, the method for obtaining high-frequency vehicle usage time periods is as follows:

[0019] S1. Record the time when the car owner starts the vehicle each time within a day, obtain the time difference data between that time and the reference time, and mark the time difference data corresponding to each vehicle start as the recorded value.

[0020] S2. Obtain the record values ​​for each day within n days, and label each record value in ascending order as C1, C2, ..., Cm. Obtain the number of record values ​​less than or equal to C1 + Cy, and label the number of these record values ​​as Q1.

[0021] S3. Delete record value C1, then get the smallest record value among the remaining record values, i.e., C2, get the number of record values ​​less than or equal to C2 + Cy, mark the number of record values ​​as Q2, and then get Q3 to Qm in sequence according to the method in steps S2 and S3, where Cy is the preset duration;

[0022] S4. Obtain Qi values ​​that are greater than or equal to the preset value Qy, and label these Qi values ​​in descending order as q1, q2, ..., qj. Obtain the Ci values ​​corresponding to q1 to qj, and label the qr values ​​corresponding to these j Ci values ​​in descending order as c1, c2, ..., cj.

[0023] S5. First, obtain the maximum value q1 from q1 to qj and the corresponding c1. Calculate the cr values ​​in the range of less than or equal to c1+Cy and greater than or equal to c1-Cy. Delete the qr values ​​and q1 values ​​corresponding to these cr values. Set the q1 value as the marker point data.

[0024] S6. Obtain the maximum value among the remaining qr values, and then obtain the data of each marker point according to the method in step S5. Then obtain the record value corresponding to each marker point data, thereby obtaining several time periods with the most record values ​​in the past n days, and marking them as high-frequency vehicle use time periods.

[0025] Where 1≤r≤j, 1≤i≤m.

[0026] As a further aspect of the present invention, the value of Qy is n / 2.

[0027] As a further embodiment of the present invention, the value of Cy is 15min.

[0028] As a further aspect of the present invention, if the vehicle is turned off within 5 minutes after starting, then the vehicle start-up is not included in the statistics of step S1.

[0029] As a further embodiment of the present invention, after the terminal device sends the control information for remote start of the air conditioner to the communication module, before the vehicle air conditioner starts cooling or heating, the vehicle air conditioner first turns on only the fan and executes external circulation. The window opening gap is controlled by the window control module. After a preset working time, the window is controlled to close by the window control module and the cooling or heating work begins.

[0030] As a further aspect of the present invention, the car air conditioning remote start system also includes a rain sensor for sensing rainfall in the external environment of the car and transmitting information on whether it is raining to the controller.

[0031] The window control module is used to control the raising and lowering of the windows and the degree of raising and lowering.

[0032] When the vehicle's external environment is detected to be raining, if the terminal device sends a remote start control signal for the air conditioning to the communication module, the window control module will not open the windows.

[0033] As a further aspect of the present invention, the method for obtaining the balancing time T is as follows:

[0034] Each time the air conditioner is remotely started on the terminal device, the real-time balancing time is recorded, as well as the corresponding in-vehicle temperature and outside temperature when the air conditioner is started. The acquired temperature data and balancing time are used to learn the relationship between balancing time, outside temperature and in-vehicle temperature.

[0035] The temperature detection module acquires the in-vehicle temperature Tn and the outside temperature Tw in real time, and obtains the corresponding equilibrium time based on the real-time in-vehicle temperature Tn and the outside temperature Tw.

[0036] The beneficial effects of this invention are:

[0037] (1) This invention records the time when the user starts the vehicle, and after analysis and processing, obtains the time period when the user usually starts the vehicle. Then, when the corresponding time period is reached in real time, it actively sends a message to remind the user to remotely start the air conditioner or make an appointment for remotely starting the air conditioner. This can prevent the user from forgetting to start the car remotely when they need to use the car, and also prevent the situation where the working time reserved for the car air conditioner is insufficient when the user performs the operation of remotely starting the air conditioner, resulting in the temperature inside the vehicle not reaching the expected value when the user enters the vehicle. This significantly improves the experience of remotely starting the air conditioner. In addition, by setting a balance time and determining the air conditioner start time according to the balance time, the problem of energy waste caused by the air conditioner being on for a long time and the user not being able to get into the car in time is avoided.

[0038] (2) The present invention uses a preset constant power to regulate the temperature inside the vehicle, which can reduce the pressure on the air conditioning cooling or heating components and reduce the engine and circuit load at the beginning of startup, thereby protecting the vehicle engine, compressor and circuit components.

[0039] (3) Before the vehicle air conditioner cools or heats, the vehicle air conditioner turns on and first turns on only the fan and performs external circulation. The window control module controls the window to open a certain gap. After the preset working time, the window control module controls the window to close and starts cooling or heating, thereby effectively reducing the concentration of toxic gases in the vehicle, realizing ventilation of the vehicle environment, and protecting the safety of the occupants.

[0040] (4) When the external environment of the car is detected to be in a rainy state, if the terminal device sends a control signal to the communication module to remotely start the air conditioner, the air conditioner will first turn on the fan and execute the external circulation. The window control module will not open the window and will start the cooling or heating work after the external circulation is turned on for a preset time. Attached Figure Description

[0041] The invention will now be further described with reference to the accompanying drawings.

[0042] Figure 1 This is a schematic diagram of the framework structure of the remote start system for automotive air conditioning of the present invention. Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] A remote start system for car air conditioning, such as Figure 1 As shown, it includes:

[0045] The temperature detection module is used to detect the temperature inside and outside the vehicle. It should be noted that the temperature detection module should be placed away from the air conditioning vents as much as possible to improve the accuracy and stability of temperature detection.

[0046] The temperature control module is used to adjust the operating temperature and fan speed of the vehicle's air conditioning system.

[0047] Rain sensors are used to detect rainfall in the external environment of the car and transmit the information about whether it is raining to the controller.

[0048] The window control module is used to control the raising and lowering of the windows and the degree of raising and lowering.

[0049] It is important to note that the operation of the window control module also requires the corresponding anti-theft system to detect abnormal intrusions and prevent criminals from using the ventilation gaps in the window to commit theft or other illegal activities.

[0050] The communication module is used to establish a communication connection with the terminal device and receive remote start control information for the air conditioner sent by the terminal device. The remote start control information for the air conditioner can be information such as starting the air conditioner at this time, scheduling the remote start of the air conditioner at a certain time, or needing to use the vehicle at a certain time.

[0051] The working method of the above-mentioned remote start system for automotive air conditioning includes the following steps:

[0052] The first step is to obtain the high-frequency usage time periods of the car owner within a certain period of time. The high-frequency usage time periods refer to the concentrated time points when the car owner starts the vehicle within a certain period of time.

[0053] Specifically, the method for obtaining high-frequency car usage time periods is as follows:

[0054] S1. Record the time when the car owner starts the vehicle each time within a day, obtain the time difference data between that time and the reference time point, and mark the time difference data corresponding to each vehicle start as the record value. The reference time point is the zero point of the corresponding date.

[0055] S2. Obtain the record values ​​for each day within n days, and label each record value in ascending order as C1, C2, ..., Cm. Obtain the number of record values ​​less than or equal to C1 + Cy, and label the number of these record values ​​as Q1.

[0056] S3. Delete record value C1, then obtain the smallest record value among the remaining record values, namely C2, obtain the number of record values ​​less than or equal to C2 + Cy, mark the number of record values ​​as Q2, and then obtain Q3 to Qm in sequence according to the method in steps S2 and S3, where m is the number of record values, and Cy is the preset time length. In one embodiment of the present invention, the value of Cy is 15min.

[0057] S4. Obtain Qi values ​​that are greater than or equal to a preset value Qy, and label these Qi values ​​in descending order as q1, q2, ..., qj. Obtain Ci values ​​corresponding to q1 to qj, and label the qr values ​​corresponding to these j Ci values ​​in descending order as c1, c2, ..., cj. In one embodiment of the present invention, the value of Qy is n / 2.

[0058] S5. First, obtain the maximum value q1 from q1 to qj and the corresponding c1. Calculate the cr values ​​in the range of less than or equal to c1+Cy and greater than or equal to c1-Cy. Delete the qr values ​​and q1 values ​​corresponding to these cr values. Set the q1 value as the marker point data.

[0059] S6. Obtain the maximum value among the remaining qr values, and then obtain the data of each marker point according to the method in step S5. Then obtain the record value corresponding to each marker point data, thereby obtaining several time periods with the most record values ​​in the past n days. These time periods start from the corresponding cr value and end with cr+Cy. These time periods are the high-frequency vehicle usage time periods.

[0060] Where 1≤r≤j, 1≤i≤m;

[0061] In one embodiment of the present invention, if the vehicle is turned off within 5 minutes after starting, the vehicle start is not included in the statistics.

[0062] The second step is for the temperature detection module to obtain the in-vehicle temperature Tn and the outside temperature Tw. Based on the in-vehicle temperature Tn and the outside temperature Tw at this time, the real-time balance duration T is calculated. When the time difference between this time and the start point of the high-frequency vehicle use period is T+ty1, the communication module sends a prompt message to the corresponding terminal device to remind the user to remotely start the air conditioner or make a remote start appointment in time. ty1 is a preset value.

[0063] Remote start refers to the user remotely starting the air conditioner at the current moment;

[0064] Remote start scheduling refers to a user's decision to remotely start the air conditioner at a specific future time.

[0065] The third step is to remotely start the car's air conditioning to heat up or cool down the interior.

[0066] The method for remotely starting the car's air conditioning to cool down or heat up is as follows:

[0067] The vehicle owner establishes a connection with the communication module through the terminal device and sends control information for remote start of the air conditioner through the terminal device to the communication module;

[0068] If the air conditioner is required to be turned on at the current moment, the air conditioner will be turned on immediately and will cool or heat at the preset power.

[0069] If the air conditioning is scheduled to turn on at a future time, the real-time interior temperature and exterior temperature are obtained. Based on the current interior and exterior temperatures and the preset cooling or heating power, the balance time T is determined. If T is greater than t1, the air conditioning will operate in inverter mode to increase cooling and heating power. Conversely, if T is less than or equal to t1, the air conditioning will delay cooling or heating until t1 = T + ty, at which point the air conditioning will begin the corresponding cooling or heating operation. Here, ty is a preset value greater than or equal to 0, and t1 is the time from the current time to the scheduled time.

[0070] The preset cooling or heating power is a constant power set according to the air conditioning temperature value set by the user.

[0071] Using preset power to regulate the temperature inside the vehicle can reduce the pressure on the air conditioning cooling or heating components, and reduce the load on the engine and electrical system during the initial startup, thus helping to protect the vehicle's engine, compressor, and electrical components.

[0072] The equilibrium time T refers to the time it takes for the car's interior to reach a temperature equilibrium state after the car's air conditioner cools or heats at a preset power. The temperature equilibrium state means that the temperature inside the car changes within a preset time t2, which is less than a preset value T1.

[0073] In one embodiment of the present invention, the method for obtaining the balancing time T is as follows:

[0074] Each time the air conditioner is remotely started on the terminal device, the real-time balance time is recorded, as well as the corresponding in-vehicle temperature and outside temperature at the time of starting the air conditioner. The acquired temperature data and balance time are learned to obtain the relationship between balance time, outside temperature and in-vehicle temperature. Thus, the in-vehicle temperature Tn and outside temperature Tw are obtained in real time through the temperature detection module, and the corresponding balance time is obtained based on the real-time in-vehicle temperature Tn and outside temperature Tw.

[0075] In one embodiment of the present invention, after the terminal device sends the control information for remote start of the air conditioner to the communication module, before the vehicle air conditioner starts cooling or heating, the vehicle air conditioner first turns on only the fan and executes external circulation. The window control module controls the window to open a certain gap. After a preset working time, the window control module controls the window to close and starts cooling or heating. This can reduce the concentration of toxic gases in the vehicle, realize the ventilation of the vehicle environment, and protect the safety of the occupants.

[0076] In one embodiment of the present invention, a rain sensor is set to detect whether it is raining in the external environment of the car. When it is detected that the external environment of the car is raining, if the terminal device sends a control signal to the communication module to remotely start the air conditioner, the air conditioner will first turn on the fan and execute the external circulation. The window control module will not open the windows. After the external circulation is turned on for a preset time, the cooling or heating work will begin.

[0077] This invention records the time a user starts their vehicle and, after analysis and processing, identifies the time periods during which the user frequently starts their vehicle. When the corresponding time period arrives, the invention proactively sends a reminder to the user to remotely start the air conditioning or schedule a remote start. This prevents users from forgetting to remotely start their vehicle when needed and avoids situations where insufficient time is allowed for the air conditioning to operate when the user performs a remote start, resulting in the vehicle's interior temperature not reaching the expected value upon entry. This significantly improves the remote air conditioning start experience.
