Therefore, the vehicle-mounted terminal can acquire the first real-time temperature with low delay, the timeliness of the first real-time temperature can be improved, and the calibration accuracy can be improved.

In the embodiment of the application, the vehicle-mounted terminal can execute the seat temperature calibration method disclosed in the embodiment of the application when detecting the calibration trigger instruction so as to start temperature calibration. The calibration trigger command may carry a seat surface target temperature, i.e., a desired temperature value for the seat surface. The in-vehicle terminal may provide a plurality of different temperature regulation gears to the user, and each temperature regulation gear may correspond to one desired temperature value. The seat surface target temperature can be defined by a developer, and when calibration is completed, the expected temperature value corresponding to each temperature control gear can be the seat surface target temperature value. For example, the vehicle-mounted terminal can provide 3 different temperature control gears, wherein the temperature of the gear 1 corresponds to 34 ℃, the temperature of the gear 2 corresponds to 38 ℃, and the temperature of the gear corresponds to 42 ℃. The above-mentioned 34 ℃, 38 ℃ and 42 ℃ can be the target temperature of the surface of the seat to be calibrated.

320. And controlling the on-off of the heating circuit according to the comparison result of the first real-time temperature and the target temperature on the surface of the seat.

In this embodiment, the vehicle-mounted terminal may control the heating circuit to be turned on or off according to the comparison result, so that the first real-time temperature may reach the target temperature of the seat surface. For example, the in-vehicle terminal may control the on/off of the heat generating circuit through a switching element included in the heat generating circuit.

In one embodiment, the in-vehicle terminal may turn on the heating circuit when the first real-time temperature is lower than the target temperature of the surface of the seat, so that the power supply supplies power to the heating device included in the heating circuit. The heating device generates heat under the action of current, and the temperature in the seat gradually rises until the first real-time temperature reaches the target temperature of the surface of the seat. When the first real-time temperature reaches the target temperature of the surface of the seat, the vehicle-mounted terminal can disconnect the heating circuit, so that the heating device does not generate heat any more and the temperature does not rise any more. For example, before calibration, the heating circuit may be in an off state, the first real-time temperature of the seat surface is 28 ℃ below the target temperature of the seat surface by 34 ℃, and the vehicle-mounted terminal may turn on the heating circuit.

In one embodiment, the in-vehicle terminal may disconnect the heating circuit when the first real-time temperature is higher than the target temperature of the seat surface, so that the power supply no longer supplies power to the heating device until the first real-time temperature is reduced to the target temperature of the seat surface. When the first real-time temperature is reduced to the target temperature of the surface of the seat, the vehicle-mounted terminal can conduct the heating circuit again. For example, before calibration, the heating circuit may be in a conducting state, and due to long-term heating, the first real-time temperature of the seat surface is 40 ℃ and is 34 ℃ higher than the target temperature of the seat surface, and the vehicle-mounted terminal may disconnect the heating circuit.

In the embodiment of the application, the temperature of the seat surface can be stabilized near the target temperature of the seat surface by continuously controlling the on and off of the heating circuit.

330. And when the first real-time temperature reaches the target temperature of the surface of the seat, acquiring a second real-time temperature inside the seat currently detected by the second temperature detection device.

In the embodiment of the application, when the first real-time temperature of the seat surface reaches the target temperature of the seat surface, the vehicle-mounted terminal may acquire a second real-time temperature inside the seat through the second temperature detection device. That is, when the seat interior reaches this second real-time temperature, the temperature that is ultimately conducted to the seat surface is the first real-time temperature due to the absorption of heat by the seat filler. For example, when the temperature of the seat interior reached 40 ℃, the temperature of the seat surface was 34 ℃, and a temperature difference of 6 ℃ existed between the seat surface and the seat interior.

In the embodiment of the present application, the first real-time temperature and the second real-time temperature may both correspond to a timestamp. The timestamp corresponding to the first real-time temperature may be recorded when the first temperature detection device detects the first real-time temperature, or may be recorded when the vehicle-mounted terminal receives the first real-time temperature sent by the data transmission device, which is not limited specifically. Accordingly, the timestamp corresponding to the second real-time temperature may be recorded by the second temperature detection device when the second real-time temperature is detected, or recorded by the vehicle-mounted terminal when the second real-time temperature sent by the second detection device is received.

When detecting that the currently received first real-time temperature reaches the seat surface target temperature, the vehicle-mounted terminal can read the timestamp corresponding to the first real-time temperature, and find out the second real-time temperature corresponding to the timestamp from the obtained multiple second real-time temperatures as the currently detected second real-time temperature inside the seat.

340. And calibrating the obtained second real-time temperature to be the seat internal target temperature corresponding to the seat surface target temperature.

In the embodiment of the present application, the target temperature of the seat interior corresponding to the target temperature of the seat surface may refer to a temperature value that the seat interior should reach in order for the seat surface to reach the target temperature of the seat surface. Optionally, after the vehicle-mounted terminal calibrates the currently acquired second real-time temperature to the corresponding seat internal target temperature, the corresponding relationship between the seat surface target temperature and the seat internal target temperature may be stored, so as to facilitate subsequent searching.

In the embodiment of the application, the temperature of the surface of the seat detected by the first temperature detection device arranged on the surface of the seat is acquired through the data transmission equipment, the first real-time temperature of the surface of the seat and the second real-time temperature inside the seat can be acquired by the vehicle-mounted terminal in real time, so that the vehicle-mounted terminal can control the on-off of the heating circuit at any time according to the change of the first real-time temperature, the temperature of the surface of the seat can be accurately controlled to rise to the target temperature, and the corresponding relation between the target temperature of the surface of the seat and the target temperature inside the seat can be accurately calibrated through the first real-time temperature and the second real.

In addition, the vehicle-mounted terminal acquires the first real-time temperature through the data transmission equipment, so that the whole calibration system can form a closed loop. After the heat generating device is energized, it takes a certain time to raise the temperature of the seat surface to the target temperature. The calibration system based on the closed loop enables the vehicle-mounted terminal to acquire the temperature information of the surface of the seat in real time, and can reduce the turn-on or turn-off times of the heating circuit when the detected temperature of the surface of the seat is increased to the target temperature in time, so that the time required by calibration is reduced, and the corresponding relation between the target temperature of the surface of the seat and the target temperature inside the seat can be calibrated quickly.

For example, in the related art, the vehicle-mounted terminal cannot acquire the temperature information of the surface of the seat in real time, and the vehicle-mounted terminal needs to set a possible preset temperature inside the seat, for example, 38 ℃. The vehicle-mounted terminal controls the on-off of the heating circuit by taking 38 ℃ as a target, for example, controls the heating circuit to be conducted until the second temperature detection device in the seat detects that the real-time temperature in the seat reaches 38 ℃. At this time, the temperature of the surface of the seat needs to be manually detected by a developer, and if the temperature of the surface of the seat is 32 ℃ and is inconsistent with the target temperature of the surface of the seat, which needs to be calibrated, of 34 ℃, the developer needs to adjust the control logic of the vehicle-mounted terminal on the heating circuit again, so that the vehicle-mounted terminal controls the on-off of the heating circuit with the temperature of 40 ℃ as a target. Therefore, if the vehicle-mounted terminal cannot acquire the temperature information of the surface of the seat in real time, the heating circuit can be controlled only by taking the temperature inside the vehicle as a target, so that the control logic of the vehicle-mounted terminal on the heating circuit needs to be adjusted for many times, and the calibration time is too long.

In the embodiment of the application, the vehicle-mounted terminal can acquire the temperature information of the surface of the seat in real time, so that the vehicle-mounted terminal does not need to preset the preset temperature in the vehicle, directly controls the heating circuit by taking the first real-time temperature of the surface of the seat as a target, does not need to adjust the control logic of the vehicle-mounted terminal on the heating circuit for many times, and can shorten the time required by calibration.

For example, the seat temperature calibration method shown in fig. 3 will now be described with reference to fig. 2A.

In operation, the in-vehicle terminal 210 may detect a calibration trigger that may carry a target temperature for the surface of the seat that is being calibrated. When detecting the calibration trigger command, the in-vehicle terminal 210 may turn on the heating circuit, so that the power supply supplies power to the one or more heating devices 251. The heat generating device 251 generates heat by the current, and the temperature inside the seat gradually increases. Meanwhile, the first temperature detection device 230 may feed back the detected first real-time temperature to the in-vehicle terminal 210. The in-vehicle terminal 210 determines whether the received first real-time temperature has reached the user-desired seat surface target temperature. If the first real-time temperature does not reach the target temperature of the surface of the seat, the conduction state of the heating circuit is kept, so that the heating device 251 continues to heat; if the first real-time temperature has reached the target temperature of the seat, the vehicle-mounted terminal 210 may disconnect the heating circuit, so that the power supply stops supplying power to the heating device 251, so that the temperature inside the seat does not rise any more. Meanwhile, the in-vehicle terminal 210 may acquire a second real-time temperature currently detected by the second temperature detecting device 240 and scale the second real-time temperature as a seat interior target temperature corresponding to the seat surface target temperature.

Referring to fig. 4, fig. 4 is a schematic flow chart of another seat temperature calibration method disclosed in the embodiment of the present application, which can be applied to any one of the vehicle-mounted terminals disclosed in the foregoing embodiments. As shown in fig. 4, the method may include the steps of:

410. and when a calibration trigger instruction is detected, receiving a first real-time temperature sent by the data transmission equipment based on local area network communication connection.

In this embodiment, the first real-time temperature may be that the first temperature detection device may send the first real-time temperature to the data transmission apparatus based on a serial communication connection with the data transmission apparatus.

420. And controlling the on-off of the heating circuit according to the comparison result of the first real-time temperature and the target temperature on the surface of the seat.

In the embodiment of the present application, the implementation of steps 410 to 420 can refer to the description of steps 310 to 320 in the foregoing embodiment, and the following description is omitted.

430. And when the first real-time temperature reaches the seat surface target temperature and is in a stable state, acquiring a second real-time temperature inside the seat currently detected by the second temperature detection device.

In the embodiment of the present application, the first real-time temperature being in the steady state may mean that the first real-time temperature is less fluctuated over a certain period of time, that is, the temperature of the seat surface is maintained around the target temperature of the seat surface. When the first real-time temperature is in a stable state, the second real-time temperature is acquired, so that the accuracy of the calibrated corresponding relation can be improved.

In one embodiment, the in-vehicle terminal may determine whether the first real-time temperature is in a steady state according to a duration recorded by the timer when the first real-time temperature reaches the seat surface target temperature. The timer may be started when the calibration trigger command is detected, or may be started when the first real-time temperature first reaches the target temperature of the seat surface.

When the vehicle-mounted terminal detects that the first real-time temperature reaches the target temperature of the surface of the seat, the time length recorded by the timer can be obtained. If the duration recorded by the current timer does not exceed the first duration, the vehicle-mounted terminal can judge that the first real-time temperature is not in a stable state; if the duration recorded by the current timer exceeds the first duration, the vehicle-mounted terminal can judge that the first real-time temperature is in a stable state and execute the step of acquiring the second real-time temperature. The first period of time described above may be set according to an empirical value of the period of time for which the heat generating device is warmed from room temperature to the target temperature of the seat surface and is maintained in a steady state. The first period of time may be set to a period of time longer than the above-described temperature-increasing period of time, for example, may be set to 2 hours, in consideration of the absorption of heat by the filler, but is not limited thereto. That is, the temperature of the seat surface may be defaulted to a steady state when the length of time recorded by the timer exceeds the first length of time.

In this embodiment, it is considered that a longer time is required for the temperature response to stabilize to a certain target temperature value after the heat generating device is powered on. Therefore, when the first real-time temperature is detected to reach the seat surface target temperature and the time recorded by the timer exceeds the first time, the second real-time temperature is obtained, the necessary temperature rise time is reserved, the problem that the number of times of switching on or switching off a heating circuit is large due to unstable temperature can be reduced, and the time required by calibration is shortened.

In one embodiment, the vehicle-mounted terminal can also judge whether the first real-time temperature is in a stable state according to the fluctuation of the first real-time temperature in a period of time.

The vehicle-mounted terminal may determine that the first real-time temperature is in a stable state when detecting that the variation of the first real-time temperature within the second time period is smaller than a preset threshold, so as to execute the step of acquiring the second real-time temperature. The second time period may be set according to the actual service requirement, for example, may be set to 1 hour, but is not limited thereto. Optionally, the second duration may be set to be shorter than the first duration, which is beneficial to increase the calibration speed. In addition, the preset threshold may be set to an acceptable error, for example, may be set to 1 ℃, but is not limited thereto. Therefore, the time required for calibration can be further reduced.

In this embodiment, whether the first real-time temperature is already in a steady state can be accurately detected based on the fluctuation of the first real-time temperature over a period of time, thereby improving the accuracy of the calibrated correspondence. Meanwhile, compared with a mode of triggering timing when a calibration triggering instruction is detected, the method is beneficial to accelerating the calibration speed and further reducing the time required by calibration.

440. The second real-time temperature is calibrated to a seat interior target temperature corresponding to the seat surface target temperature.

450. The correspondence between the seat surface target temperature and the seat interior target temperature is stored.

In the embodiment of the application, the vehicle-mounted terminal can store the corresponding relation in a local cache or a memory of the vehicle-mounted terminal, so that the corresponding relation calibrated by the vehicle-mounted terminal can be quickly read when in use. Or the corresponding relation can be stored in the cloud equipment in communication connection with the vehicle-mounted terminal, so that other terminals in communication connection with the cloud equipment can obtain the corresponding relation from the cloud equipment, and unnecessary repeated calibration can be reduced.

460. And when a heating trigger instruction carrying the first target temperature is detected, acquiring a second target temperature in the seat corresponding to the first target temperature according to the corresponding relation.

In the embodiment of the application, the heating triggering instruction may be triggered by a user through a vehicle-mounted terminal. The vehicle-mounted terminal can provide a plurality of different temperature regulating gears for a user, and when the vehicle-mounted terminal detects that the user selects a certain temperature regulating gear, the vehicle-mounted terminal can generate a heating trigger instruction. The heating instruction may also carry a heating instruction until the seat surface temperature is reached, i.e., a temperature value corresponding to the temperature control gear selected by the user. After the heating trigger instruction is detected, the vehicle-mounted terminal can search for a second target temperature inside the seat corresponding to the first target temperature from the corresponding relation stored locally or in a cloud. For example, the first target temperature carried by the heating trigger command may be 34 ℃, and the corresponding second target temperature may be determined to be 40 ℃ according to the corresponding relationship.

470. And acquiring a third real-time temperature inside the seat detected by the second temperature detection device in real time.

480. And controlling the on-off of the heating circuit according to the comparison result of the third real-time temperature and the second target temperature until the third real-time temperature reaches the second target temperature.

In this embodiment of the application, the second target temperature is a temperature increase target, and the vehicle-mounted terminal may turn on the heating circuit when the currently detected third real-time temperature is lower than the second target temperature, so that the heating device heats and increases the temperature. The vehicle-mounted terminal can also disconnect the heating circuit when the currently detected third real-time temperature is higher than the second target temperature, so that the heating device stops heating. When the third real-time temperature reaches the second target temperature, the temperature of the seat surface may have reached the first target temperature desired by the user based on the previously calibrated correspondence. For example, when the third real-time temperature of the seat interior is detected to be 40 ℃, the temperature of the seat surface may be 34 ℃ to reach the temperature value desired by the user.

In the embodiment of the present application, after the steps 410 to 450 are performed, the steps 460 to 480 may be performed after a time interval. For example, the calibration may be performed in steps 410 to 450 before the vehicle leaves the factory, and the calibrated correspondence may be applied in steps 460 to 480 after the vehicle leaves the factory and is delivered to the user.

As can be seen, in the foregoing embodiment, the first real-time temperature may be fed back to the in-vehicle terminal in real time based on the communication connection between the in-vehicle terminal, the data transmission device, and the first temperature detection apparatus. The vehicle-mounted terminal can acquire the first real-time temperature on the surface of the seat and the second real-time temperature inside the seat at the same time, so that the corresponding relation between the target temperature on the surface of the seat and the target temperature inside the seat can be accurately marked. In addition, the time required for calibration can be reduced based on a closed-loop calibration system. Further, when the first real-time temperature is in a stable state, the second real-time temperature is obtained, so that the accuracy of the calibrated corresponding relation can be improved. Further, the calibrated correspondence is applied so that the heat generation of the heat generating device can compensate in advance the amount of heat that the filler may absorb, so that the in-vehicle terminal can accurately control the temperature of the seat surface to the desired value of the user.

Referring to fig. 5, fig. 5 is a schematic flow chart of a seat temperature control method disclosed in an embodiment of the present application, where the method can be applied to any one of the vehicle-mounted terminals disclosed in the foregoing embodiments. As shown in fig. 5, the method may include the steps of:

510. when a heating trigger instruction carrying a seat surface target temperature is detected, a seat internal target temperature which is calibrated in advance and corresponds to the seat surface target temperature is obtained.

In the embodiment of the application, the heating triggering instruction may be triggered by a user through a vehicle-mounted terminal. The target temperature of the seat surface carried by the heating trigger instruction may be a temperature value desired by the user. The in-vehicle terminal may acquire the seat internal target temperature corresponding to the seat surface target temperature from the correspondence stored locally or in the cloud, but is not limited thereto. The seat interior target temperature is a second real-time temperature recorded when a first real-time temperature detected by a first temperature detection device on the surface of the seat reaches the seat surface target temperature in real time, and the second real-time temperature is detected by a second temperature detection device inside the seat; and the first real-time temperature is transmitted to the vehicle-mounted terminal through the data transmission equipment. The method for calibrating the seat internal target temperature corresponding to the seat surface target temperature can be shown as the seat temperature calibration method disclosed in the foregoing embodiment, and details are not repeated below.

It should be noted that, in the embodiment of the present application, when the in-vehicle terminal executes the seat temperature control method shown in fig. 5, there may be no need for a communication connection with the data transmission device, and the surface of the car seat may not be provided with the first temperature detection device.

520. And acquiring a third real-time temperature inside the seat detected by the second temperature detection device in real time.

530. Comparing the third real-time temperature with the target temperature inside the seat; if the third real-time temperature is higher than the target temperature inside the seat, go to step 540; if the third real-time temperature is lower than the seat interior target temperature, step 550 is performed.

540. The heating circuit is opened and execution returns to step 530.

In the embodiment of the application, when the third real-time temperature is higher than the target temperature of the surface of the seat, the heating circuit is disconnected, so that the power supply does not supply power to the heating device any more, and the temperature inside the seat is gradually reduced.

550. The heating circuit is turned on and the process returns to step 530.

In the embodiment of the application, when the third real-time temperature is lower than the target temperature of the surface of the seat, the heating circuit is turned on, so that the power supply supplies power to the heating device included in the heating circuit, and the temperature inside the seat gradually rises.

In this embodiment of the application, after the steps 530 to 550 are executed, the vehicle-mounted terminal may control the on/off of the heating circuit according to the comparison result between the third real-time temperature and the target temperature inside the seat. By continuously controlling the on/off of the heating circuit, the temperature inside the seat can be stably maintained at a temperature close to the target temperature inside the seat. As can be seen from the previously calibrated correspondence relationship, when the temperature inside the seat reaches the seat inside target temperature, the temperature of the seat surface can be maintained in the vicinity of the seat surface target temperature, so that the temperature of the seat surface coincides with the temperature value desired by the user. Therefore, the in-vehicle terminal can accurately control the temperature of the seat surface to the desired value of the user.
