[0024] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0025] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0026] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0027] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0028] Generally speaking, the seat heating control solution can detect the temperature through the temperature sensor and feed it back to the heating controller, which controls the on and off of the seat heater according to the temperature, and then detects the temperature of the seat heater and the seat in real time, and reports the fault to the heating controller when the seat heater fails, and finally controls the heating controller to disconnect the driving power of the seat heater. However, there is still a certain probability that the heater or temperature sensor will fail, which will eventually lead to excessive seat temperature, seat ablation or even fire.

[0029] To solve the above problems, combined with Figures 1 to 7 As shown, an embodiment of the present application provides a vehicle seat heating control method, a control device 300, a vehicle and a computer-readable storage medium.

[0030] In an exemplary embodiment of the present application, Figure 1 As shown, Figure 1 A partial structural schematic diagram of a vehicle seat provided by an embodiment of the present application is shown. The vehicle seat includes a heating controller, a switch element and a seat heater, wherein the heating controller, the seat heater and the switch element are connected in series to form a heating circuit. The heating controller is connected to the vehicle power supply.

[0031] For example, the switch element may be a transistor, a MOS tube or a relay.

[0032] It should be understood that the heating controller is used to control the switch of the seat heater and provide power to the seat heater. The switch element is used to disconnect the current of the heating circuit to disconnect the power supply of the seat heater when the heating controller does not control the seat heater to turn off.

[0033] Furthermore, the vehicle seat also includes a temperature sensor, which is installed in the vehicle seat and is used to detect the temperature of the vehicle seat. The temperature sensor is connected to the heating controller to feed back temperature data to the heating controller after detecting the temperature of the vehicle seat.

[0034] In an exemplary embodiment of the present application, Figure 2 As shown, Figure 2 The schematic flow chart of steps S210-S230 of a vehicle seat heating control method provided by an embodiment of the present application is shown. The method is executed by a vehicle terminal or a seat controller, and includes steps S210 to S230, which are described in detail as follows:

[0035] S210: Acquire heating information of the seat, where the heating information includes a temperature value of the seat and heating control information of a heating controller.

[0036] For example, the temperature value of the seat can be obtained by a temperature sensor installed in the vehicle seat. The heating control information can be derived from the heating control information input by the user, that is, the heating controller controls the heater to heat according to the heating control information input by the user.

[0037] S220: If the heating information of the seat does not meet the preset heating information, it is determined that the seat is in an abnormal heating state.

[0038] It should be understood that after obtaining the heating information of the seat, it is also necessary to determine whether the heating information of the seat meets the preset heating information to determine whether the seat is in an abnormal heating state or a normal heating state.

[0039] In an exemplary embodiment of the present application, Figure 3 As shown, Figure 3 The schematic flow chart of steps S221-S222 of a vehicle seat heating control method provided by an embodiment of the present application is shown. The method for determining whether the seat heating information meets the preset heating information includes steps S221 to S222, which are described in detail as follows:

[0040] Step S221: Acquire the execution information of the seat heater.

[0041] It should be understood that after the heating controller sends a heating or heating-off instruction to the seat heater based on the heating control information, the execution information of the seat heater is obtained, so that the situation in which the seat heater executes the heating or heating-off instruction issued by the heating controller can be obtained, thereby determining whether there is a fault in the seat heater or the heating controller.

[0042] Step S222: If the execution information does not match the heating control information, it is determined that the heating information of the seat does not meet the preset heating information.

[0043] For example, if the heating controller sends a heating instruction to the seat heater according to the heating control information, but the seat heater is not turned on, then the execution information of the seat heater obtained does not match the heating control information, and it can be determined that the seat heater or the heating controller is faulty; or, if the heating controller does not send a heating instruction to the seat heater according to the heating control information, but the seat heater is turned on for heating, then the execution information of the seat heater obtained does not match the heating control information, and it can be determined that the seat heater or the heating controller is faulty.

[0044] It should be understood that when any component of the seat heater, heating controller or temperature sensor fails, or when a cross-current occurs in the heating circuit, the execution information and the heating control information may not match.

[0045] In an exemplary embodiment of the present application, Figure 4 As shown, Figure 4 The schematic flow chart of steps S221'-S223' of a vehicle seat heating control method provided by an embodiment of the present application is shown. The method for determining whether the seat heating information meets the preset heating information also includes steps S221' to S223', which are described in detail as follows:

[0046] Step S221 ′: in response to the heating controller's instruction to turn on or off the heating, acquiring the seat heater's execution information.

[0047] It should be understood that after the seat controller sends thermal control information to the heating controller, and the heating controller sends a heating or heating-off instruction to the seat heater based on the heating control information, the execution information of the seat heater is obtained, and the situation in which the seat heater executes the heating or heating-off instruction issued by the heating controller can be obtained, thereby determining whether there is a fault in the seat heater or the heating controller.

[0048] Step S222 ′: If the execution information matches the heating control information, the current temperature value of the seat heater is obtained.

[0049] It should be understood that the matching of execution information and heating control information may mean: after the heating controller sends an instruction to the seat heater, if the seat heater is executed, it is determined that the execution information matches the heating control information; if not executed, it is determined that the execution information does not match the heating control information.

[0050] For example, if the heating controller sends a heating instruction to the seat heater according to the heating control information, the seat heater is turned on; and if the heating controller sends a heating shut-off instruction to the seat heater according to the heating control information, the seat heater is turned off. At this time, the execution information of the seat heater obtained matches the heating control information, and it can be judged that there is most likely no fault in the seat heater or the heating controller.

[0051] Furthermore, in order to determine the execution of the heating control information by the seat heater, the vehicle seat heating control method further includes:

[0052] Step S223 ′: If the temperature mapping relationship between the current temperature value of the seat heater and the current temperature value of the seat does not satisfy the preset temperature relationship, it is determined that the heating information of the seat does not satisfy the preset heating information.

[0053] For example, after the seat heater starts working, it will heat the seat through its own temperature. As the seat heater continues to heat the seat, the temperature of the seat will gradually increase. Therefore, a temperature change curve about the seat temperature change can be calibrated according to the temperature value and heating time of the seat heater, and then used as a reference for the preset temperature relationship; then determine whether the temperature mapping relationship between the current temperature value of the seat heater and the current temperature value of the seat meets the preset temperature relationship; if the preset temperature relationship is not met, it is determined that the heating information of the seat does not meet the preset heating information; if the preset temperature relationship is met, it is determined that the heating information of the seat meets the preset heating information.

[0054] It should be understood that, when the execution information of the seat heater matches the heating control information of the heating controller, if the heating information of the seat does not meet the preset heating information, it means that although the seat heater has executed the heating control information, it has failed to achieve the expected effect of the heating control information, and it can be confirmed that the seat heater may be faulty, or there are other circuits in series with the heating circuit.

[0055] In an exemplary embodiment of the present application, Figure 5 As shown, Figure 5 The schematic flow diagram of steps S224-S225 of a vehicle seat heating control method provided by an embodiment of the present application is shown. The method for determining whether the seat heating information meets the preset heating information also includes steps S224 to S225, which are described in detail as follows:

[0056] S224: Obtain the output current of the heating controller and the input current of the seat heater.

[0057] S225: If the current difference between the output current and the input current does not match the preset current difference, it is determined that the heating information of the seat does not meet the preset heating information.

[0058] It should be understood that if the current difference between the output current and the input current does not match the preset current difference, it means that there is a high probability that other circuits are connected to the heating circuit in series, which causes the current difference to not match the preset current difference. Among them, if the current difference between the output current and the input current does not match the preset current difference, it means that after the current difference is obtained by subtracting the input current from the output current, the current difference is not equal to the current consumed by the output current before passing through the heating circuit and entering the seat heater.

[0059] In an exemplary embodiment of the present application, the method for determining whether the heating information of the seat meets the preset heating information also includes: if the current temperature value of the seat is greater than the temperature threshold and the seat heater has not received a shutdown command, it is determined that the heating information of the seat does not meet the preset heating information.

[0060] For example, if after the seat heater is turned on, the seat is heated by the seat heater and the current temperature of the seat is continuously increased to a value greater than the temperature threshold, if the seat heater does not receive a shutdown command from the heating controller, it means that the seat heater is faulty or the temperature sensor is faulty, and the current temperature of the seat has exceeded the temperature value required by the user. Therefore, it can be determined that the heating information of the seat does not meet the preset heating information.

[0061] S230: Control the switch element to disconnect the heating circuit based on the abnormal heating state.

[0062] It should be understood that if any one, more or a combination of the above step S220 forms a situation where the preset heating information is not satisfied, it can be determined that the seat is in an abnormal heating state, and then the heating circuit can be disconnected by the switch element to avoid ablation or fire of the seat.

[0063] In an exemplary embodiment of the present application, the vehicle seat heating control method further includes: based on the abnormal heating state, controlling the vehicle's onboard terminal or the vehicle's corresponding mobile terminal to generate an over-temperature warning message, thereby prompting the user that the seat heating is abnormal and the seat heating function needs to be turned off as soon as possible. The over-temperature warning message includes one or more of a web page, a voice, and a pop-up window.

[0064] For example, when the execution information does not match the heating control information, an over-temperature warning message can be generated by controlling the vehicle's on-board terminal or the vehicle's corresponding mobile terminal. The over-temperature warning message may prompt: the heating controller is abnormal or the seat heater is abnormal, thereby prompting the user that the cause of the abnormality in the seat heating function may be due to the heating controller or the seat heater itself, so as to facilitate subsequent repairs and maintenance of the vehicle.

[0065] For example, when the execution information of the heating controller matches the heating control information, but the temperature mapping relationship between the current temperature value of the seat heater and the current temperature value of the seat does not satisfy the preset temperature relationship, the over-temperature warning information generated by controlling the vehicle's on-board terminal or the vehicle's corresponding mobile terminal may prompt: the seat heater is abnormal or the heating circuit is abnormal, thereby prompting the user that the cause of the abnormality in the seat heating function may be due to the seat heater itself, so as to facilitate subsequent repairs and maintenance of the vehicle.

[0066] For example, when the current difference between the output current of the heating controller and the input current of the seat heater does not match the preset current difference, the over-temperature warning information generated by controlling the vehicle's on-board terminal or the vehicle's corresponding mobile terminal may prompt: the heating circuit is abnormal, and then prompt the user that the cause of the abnormality in the seat heating function may be due to the abnormality caused by the heating circuit cross-current, so as to facilitate the subsequent repair and maintenance of the vehicle.

[0067] In an exemplary embodiment of the present application, the heating control method of a vehicle seat also includes: if the heating information of the seat meets the preset heating information, determining that the seat is in a normal heating state; and controlling the heating controller to send an on or off instruction to the seat heater, thereby normally turning off the seat heating function.

[0068] In the present application, since the heating control method of the vehicle seat can obtain the heating information of the vehicle in real time to understand the heating status of the seat, and when the execution information of the heating controller does not match the heating control information, when the execution information of the heating controller matches the heating control information, but the temperature mapping relationship between the current temperature value of the seat heater and the current temperature value of the seat does not meet the preset temperature relationship, the current difference between the output current of the heating controller and the input current of the seat heater does not match the preset current difference, and\or the current temperature value of the seat is greater than the temperature threshold, and the seat heater does not receive a shutdown instruction, it is determined that the heating information of the seat does not meet the preset heating information, and the seat is determined to be in an abnormal heating state, and then the switch element is controlled to disconnect the heating circuit based on the abnormal heating state. Therefore, after the vehicle seat is equipped with the seat heating function, even if the heating controller fails, the seat heater fails, or the wire connecting the seat heater is connected to other circuits, the power supply of the seat heater can be disconnected by the switch element, and finally the seat can be almost prevented from burning or fire.

[0069] In addition, the reason why the heating information does not meet the preset heating information can also be used to deduce the reason why the seat heating function is most likely to be abnormal, so that the cause can be found out as soon as possible during vehicle maintenance and repair.
