[0023] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0024] The terms "first", "second", etc. used in this application may be used herein to describe various concepts, but unless otherwise specified, these concepts are not limited by these terms. These terms are only used to distinguish one concept from another. For example, without departing from the scope of this application, a first duration may be referred to as a second duration, and similarly, a second duration may be referred to as a first duration.

[0025] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards of relevant countries and regions. For example, the requests, instructions, voltages or states involved in this application are all obtained with full authorization.

[0026] An implementation environment of a seat control method provided in an embodiment of the present application includes a car and a terminal, and the car and the terminal are connected via a wireless network.

[0027] In some embodiments, the terminal is a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart watch, etc., but is not limited thereto. Exemplarily, the terminal is a terminal used by a driver of a car, and the driver can send a seat ventilation request to the car through the terminal.

[0028] In some embodiments, the car is a new energy car, such as a pure electric car, a plug-in hybrid electric car, a fuel cell electric car, etc. The car is equipped with a remote control module, a central electronic module, a relay, a storage battery, a power battery, and a ventilation module arranged in the seat. The remote control module can also communicate with the user terminal through a wireless network. Accordingly, when the user sends a seat ventilation request to the remote control module of the car through the user terminal, the car responds to the seat ventilation request through the included module.

[0029] Figure 1 is a flow chart of a control method for a seat provided in an embodiment of the present application, the method is executed by a car, the car includes a remote control module, a central electronic module, a relay, a battery, a power battery and a ventilation module arranged in the seat, such as Figure 1 As shown, the method includes:

[0030] 101. The remote control module detects the voltage of the battery in response to the seat ventilation request sent by the terminal; when the voltage of the battery is greater than the threshold, the remote control module detects the voltage state of the vehicle; when the vehicle is not in a high-voltage state, the remote control module sends a high-voltage power-on request to the central electronic module.

[0031] In the embodiment of the present application, a ventilation module is provided in the seat of the car, and the ventilation module is used to adjust the temperature or humidity of the seat surface. The user can remotely control the car through the terminal to activate the ventilation module in the car to adjust the temperature or humidity of the seat surface in the car, so that the temperature or humidity of the seat surface can be adjusted to the user's satisfaction before the user sits on the seat, thereby improving the user's riding experience.

[0032] In the embodiment of the present application, various functions of the automobile rely on sufficient power supply. When the battery voltage is greater than the threshold, it means that the battery has sufficient power to support the basic operation of the remote control module. If the battery voltage is too low, the remote control module may not work properly. For example, communication may be interrupted or the function may not be realized when performing the remote control function. Therefore, in response to the seat ventilation request, the remote control module will detect the battery voltage to ensure that the battery voltage is sufficient before performing subsequent operations.

[0033] In an embodiment of the present application, the voltage state of the car includes a low voltage state or a high voltage state. When the car is not started, or when the power battery of the car is not powered, the car is in a low voltage state, and only the battery can power some components. When the car is in a high voltage state, the power battery of the car can power the high voltage circuit of the whole vehicle. Since the ventilation module needs power from the power battery to operate, the car being in a high voltage state means that the power battery can provide power for the ventilation module. Therefore, when the car is not in a high voltage state, it means that the power battery is not connected to the high voltage circuit of the whole vehicle. At this time, the power battery cannot power the ventilation module, and the temperature or humidity of the seat surface in the car cannot be adjusted. Therefore, in this case, a high voltage power-on request will be sent to the central electronic module to control the power battery to power the high voltage circuit of the whole vehicle, so that the car enters a high voltage state so that the power battery can power the ventilation module.

[0034] In the embodiment of the present application, the terminal is a terminal used by the user. Optionally, an application for controlling the car by the user is installed on the terminal. The user can remotely control the car through the application installed in the terminal, and can adjust the temperature or humidity of the seat surface through the application. In response to the operation, the terminal sends a seat ventilation request to the remote control module.

[0035] Among them, the threshold is an arbitrary value, for example, the threshold is 11.5V. The remote control module is a device used to realize the communication between the car and the external network. The remote control module is any type of communication module. For example, the remote control module is a T-BOX (Telematics BOX, in-vehicle intelligent terminal), and the T-BOX can communicate with the TSP (Telematics Service Provider, Internet of Vehicles Service Provider) platform. The battery is a low-voltage battery, and the battery is used to provide power for the low-voltage electrical system of the car. These low-voltage electrical systems include the vehicle's lighting system, instrument system, entertainment system, body control module, and various sensors. For example, when the vehicle is started, the battery powers the body control module, so that the body control module can complete the self-check of the car, including checking whether the door is closed, whether the tire pressure monitoring system is normal, and other body-related functions. The central electronic module (CEM) is used to coordinate and manage numerous electronic devices and functions. It can receive signals from various sensors and control units, and then issue instructions to different components of the car based on pre-set programs and logic to achieve various functions. The ventilation module can be any type of device for realizing the seat ventilation function. For example, the ventilation module includes a ventilation motor, a ventilation fan, a ventilation duct, etc. When the ventilation motor is running, it can drive the ventilation fan to rotate to generate wind, and the wind can adjust the temperature or humidity of the seat surface through the ventilation duct.

[0036] 102. The central electronic module controls the relay to close in response to the high-voltage power-on request, so as to switch the state of the vehicle to the high-voltage state, wherein when the vehicle is in the high-voltage state, the power battery can supply power to the ventilation module.

[0037] In the embodiment of the present application, the relay is used to control the on-off of the power battery and the high-voltage circuit of the whole vehicle. Only when the relay is closed can the power battery be connected to the entire high-voltage circuit and power the ventilation module. The high-voltage power-on request indicates that the power battery is connected to the high-voltage circuit of the whole vehicle. Therefore, the central electronic module controls the relay to close in response to the high-voltage power-on request so that the power battery can be connected to the entire high-voltage circuit. At this time, the state of the car is changed to a high-voltage state, so that the power battery can power the ventilation module through the high-voltage circuit of the whole vehicle.

[0038] 103. When the vehicle is in a high-voltage state, the remote control module sends a seat ventilation request to the central electronic module.

[0039] In an embodiment of the present application, when the car is in a high-voltage state, the remote control module, at this time, the power battery can supply power to the ventilation module so as to control the ventilation module to operate. Therefore, a seat ventilation request is sent to the central electronic module so that the central electronic module controls the operation of the ventilation module according to the seat ventilation request.

[0040] 104. The central electronic module controls the operation of the ventilation module in response to the seat ventilation request.

[0041] In an embodiment of the present application, after the central electronic module receives a seat ventilation request, it can control the operation of the ventilation module according to the seat ventilation request. At this time, the power battery can provide power support for the operation of the ventilation module, so that the ventilation module can operate to adjust the temperature or humidity of the seat surface.

[0042] In the solution provided by the embodiment of the present application, when the remote control module receives a seat ventilation request from outside the car, it first detects the voltage of the battery. Only when the voltage of the battery is high enough, it will detect the voltage state of the car, and when the car is not in a high-voltage state, it can control the relay to close through the central electronic module to power on the high voltage of the car, and then the remote control module sends a seat ventilation request to the central electronic module, so that the central electronic module responds to the seat ventilation request and controls the operation of the ventilation module, so that the ventilation module changes the temperature or humidity of the seat surface. In this way, a method of remotely controlling the temperature or humidity of the seat in the car is realized, and the user does not need to enter the car to adjust it. In this way, the temperature or humidity of the seat surface can meet the user's satisfaction when the user sits on the seat, thereby improving the riding experience. In addition, this control method can adjust the temperature and humidity of the seat surface while ensuring the performance of the car, ensuring the safety and control accuracy of the car.

[0043] Above Figure 1 What is shown is only the basic process of this application. The solution provided by this application will be further explained below based on a specific implementation method.

[0044] Figure 2 is a flow chart of a control method for a seat provided in an embodiment of the present application, the method is executed by a car, the car includes a remote control module, a central electronic module, a relay, a battery, a power battery and a ventilation module arranged in the seat, such as Figure 2 As shown, the method includes:

[0045] 201. The remote control module detects the voltage of the battery within a first time period in response to a seat ventilation request sent by a terminal.

[0046] In the embodiment of the present application, taking into account that the car may be in a dormant state when the car is remotely controlled, the battery voltage may increase instantaneously when the car is in a dormant state. Therefore, when the remote control module detects the battery voltage in response to the seat ventilation request, it will perform the detection for a certain period of time to detect whether the battery voltage exceeds the threshold within a period of time.

[0047] The first duration is any duration, for example, the first duration is 3 seconds or 5 seconds.

[0048] For example, the first duration is 3 seconds, the threshold is 11.5V, and the remote control module will use hardwired judgment to detect whether the battery voltage is greater than 11.5V within 3 seconds.

[0049] In a possible implementation, the seat ventilation request carries a gear position identification, a vehicle identification, and a seat identification.

[0050] In an embodiment of the present application, the ventilation module has multiple gears, and the ventilation module has different adjustment strengths on the temperature or humidity of the seat surface at different gears. The gear mark indicates the gear of the ventilation module. The gear mark can be represented in any form, for example, the gear mark is represented in the form of a number, such as the gear mark is 0, 1, 2, 3. The car logo is a unique identifier that indicates the identity of the car. The car includes multiple seats, each seat is provided with a ventilation module, and different seats have different seat logos. The seat logo can be represented in any form, for example, the seat logo is a seat name, such as the seat logo is a "driver's seat" or a "passenger seat".

[0051] In the embodiment of the present application, the seat ventilation request carries a gear position identification, a seat identification and a car identification to indicate that the seat ventilation request indicates which car and which seat the ventilation module under is to operate in which gear position.

[0052] Optionally, an application for controlling the car is installed in the terminal. The user can remotely control the car through the application installed in the terminal, and can adjust the temperature or humidity of the seat surface through the application, such as starting the ventilation module and setting the gear. The terminal sends a seat ventilation request to the remote control module in response to starting the ventilation module and setting the gear. The seat ventilation request carries the car identifier and gear identifier corresponding to the car associated with the application.

[0053] In one possible implementation, the terminal sends a seat ventilation request to the TSP platform in response to a seat ventilation operation. The TSP platform receives the seat ventilation request and sends the seat ventilation request to a remote control module in the car indicated by the car identification carried in the seat ventilation request.

[0054] 202. The remote control module detects a voltage state of the vehicle when the voltage of the battery is always greater than a threshold value within a first period of time.

[0055] In the embodiment of the present application, when the battery voltage is always greater than the threshold value within the first time period, the remote control module determines that the battery voltage is sufficient and can support subsequent operations, and therefore detects the voltage status of the vehicle.

[0056] It should be noted that the embodiment of the present application is described by taking the detection of the battery voltage within the first time period as an example, while in another embodiment, there is no need to execute the above steps 201-202, but other methods are adopted. The remote control module detects the battery voltage in response to the seat ventilation request sent by the terminal; when the battery voltage is greater than the threshold, the voltage status of the vehicle is detected.

[0057] 203. When the vehicle is not in a high voltage state, the remote control module sends a high voltage power-on request to the central electronic module.

[0058] In the embodiment of the present application, since the ventilation module needs power from the power battery to operate, the fact that the vehicle is in a high-voltage state indicates that the power battery can provide power for the ventilation module. Therefore, when the vehicle is not in a high-voltage state, it indicates that the power battery is not connected to the high-voltage circuit of the vehicle, and the power battery cannot supply power to the ventilation module. Therefore, a high-voltage power-on request is first sent to the central electronic module, so as to control the power battery to be connected to the high-voltage circuit of the vehicle, and realize high-voltage power-on, that is, the vehicle enters a high-voltage state.

[0059] In a possible implementation, the remote control module continuously sends multiple high-voltage power-on requests to the central electronic module when the vehicle is not in a high-voltage state.

[0060] In an embodiment of the present application, considering that the communication environment inside the vehicle may be subject to various interferences, or considering that the central electronic module is processing a task and may not be able to receive a high-voltage power-on request, multiple high-voltage power-on requests are continuously sent to the central electronic module to ensure that the central electronic module can receive the high-voltage power-on request and ensure the reliability of receiving the high-voltage power-on request.

[0061] For example, the central electronic module sends 5 high voltage power-on requests in succession.

[0062] 204. In response to the high-voltage power-on request, the central electronic module controls the high-voltage circuit relay to close and sends a power-on request for the battery relay to the vehicle controller.

[0063] In an embodiment of the present application, the automobile further includes a vehicle controller, and the relay includes a high-voltage circuit relay and a battery relay. The high-voltage circuit relay is used to control the on and off of the high-voltage circuit of the vehicle, and the battery relay is used to control the connection between the positive and negative poles of the power battery and the high-voltage circuit of the vehicle, and the vehicle controller is used to control the closing or disconnection of the battery relay. The vehicle controller (VCU, Vehicle Control Unit) is the core component of the electronic control system of a pure electric vehicle, which is used to coordinate the work of various systems of the vehicle so that the vehicle can run safely, efficiently and comfortably. The high-voltage circuit relay is any type of relay, for example, the high-voltage circuit relay is an IGN2 relay. The battery relay is any type of relay, for example, the battery relay is the positive and negative pole relay of the power battery.

[0064] In an embodiment of the present application, the high-voltage power-on request indicates that the power battery is connected to the high-voltage circuit of the entire vehicle. The central electronic module responds to the high-voltage power-on request, controls the high-voltage circuit relay to close, so that the high-voltage circuit of the entire vehicle is connected, and sends a power-on request for the battery relay to the vehicle controller, so that the vehicle controller can control the battery relay to close, so that the positive and negative poles of the power battery are connected to the high-voltage circuit relay.

[0065] In a possible implementation, when the central electronic module receives the same high-voltage power-on request multiple times in succession, it only needs to respond to the first received high-voltage power-on request, and subsequent high-voltage power-on requests can be ignored.

[0066] 205. The vehicle controller controls the battery relay to close in response to the power-on request for the battery relay.

[0067] In the embodiment of the present application, the vehicle controller controls the battery relay to close in response to a power-on request for the battery relay, so that the positive and negative electrodes of the power battery are connected to the high-voltage circuit relay, so that the power battery can supply power to other components through the high-voltage circuit of the vehicle. When the high-voltage circuit relay is closed and the battery relay is closed, the vehicle enters a high-voltage state, at which time the power battery can supply power to the ventilation module or other components through the high-voltage circuit of the vehicle.

[0068] It should be noted that the embodiment of the present application is explained by taking the central electronic module controlling the high-voltage circuit relay to close and the vehicle controller controlling the battery relay to close as an example. In another embodiment, there is no need to execute the above steps 204-205, but other methods are adopted. The central electronic module responds to the high-voltage power-on request and controls the relay to close to switch the state of the vehicle to the high-voltage state.

[0069] 206. When the vehicle is in a high-voltage state, the remote control module sends a seat ventilation request to the central electronic module.

[0070] In a possible implementation, step 206 includes: when the vehicle is in a high-voltage state, the remote control module sends a seat ventilation request to the central electronic module through the bus.

[0071] The bus is any type of bus, for example, the bus is a CAN (Controller Area Network, a serial communication protocol) bus.

[0072] In a possible implementation, the remote control module continuously sends multiple seat ventilation requests to the central electronic module when the vehicle is in a high-pressure state.

[0073] In an embodiment of the present application, taking into account that the communication environment inside the vehicle may be subject to various interferences, or taking into account that the central electronic module is processing a task and may not be able to receive a high-voltage power-on request, multiple seat ventilation requests are continuously sent to the central electronic module to ensure that the central electronic module can receive the seat ventilation request and ensure the reliability of receiving the seat ventilation request.

[0074] For example, the central electronic module sends 5 requests for seat ventilation in succession.

[0075] 207. The central electronic module controls the operation of the ventilation module in response to the seat ventilation request.

[0076] In a possible implementation, the seat ventilation request carries a seat identification, and step 207 includes: the central electronic module responds to the seat ventilation request and controls the operation of a ventilation module provided in the seat indicated by the seat identification according to the seat identification.

[0077] In the embodiment of the present application, the car includes a plurality of seats, each seat is provided with a ventilation module, and different seats have different seat identifiers. The seat ventilation request carries the seat identifier to indicate which seat in the car the seat ventilation request indicates the ventilation module under is to be operated.

[0078] Optionally, the seat ventilation request also carries a gear position identification, and step 207 includes: the central electronic module responds to the seat ventilation request, controls the operation of the ventilation module arranged in the seat indicated by the seat identification according to the seat identification and the gear position identification, so that the ventilation module operates according to the gear position indicated by the gear position identification.

[0079] In the embodiment of the present application, the ventilation module has multiple gears, and the ventilation module has different adjustment strengths on the temperature or humidity of the seat surface at different gears. The seat ventilation request carries a gear mark and a seat mark to indicate which seat in the car the ventilation module under which seat is to operate at which gear.

[0080] In a possible implementation, when the central electronic module receives the same seat ventilation request multiple times in succession, it only needs to respond to the first received seat ventilation request, and the subsequent seat ventilation requests can be ignored.

[0081] 208. The central electronic module sends the operating status of the ventilation module to the remote control module, and the operating status indicates the operating condition of the ventilation module.

[0082] In an embodiment of the present application, when the central electronic module controls the operation of the ventilation module, the operating status of the ventilation module can be obtained, and then the operating status of the ventilation module can be fed back to the remote control module so that it can be fed back to the terminal.

[0083] The operation status of the ventilation module indicates the operation status of the ventilation module. For example, the operation status of the ventilation module indicates whether the ventilation module operates normally and at which gear the ventilation module operates.

[0084] In a possible implementation, after receiving the seat ventilation request, the terminal electronic module needs to send the operating status of the ventilation module to the remote control module within a third time period.

[0085] The third duration is any duration, for example, the third duration is 5 seconds.

[0086] In an embodiment of the present application, after receiving a seat ventilation request, the central electronic module controls the operation of the ventilation module so that the ventilation module adjusts the temperature or humidity of the seat surface, and feeds back the operating status of the ventilation module to the remote control module within a third time period. Such a time limit is to ensure the timely response of the vehicle's electrical system to avoid affecting the normal start-up and subsequent operation of the vehicle due to too long waiting time, and it is also convenient for timely judgment of whether there is any abnormality in the power-on operation.

[0087] Optionally, after the remote control module sends a seat ventilation request to the central electronic module, if it does not receive feedback from the central electronic module on the operating status of the ventilation module within a third time period, it sends a lower high-voltage request to the central electronic module so that the central electronic module responds to the lower high-voltage request and controls the relay to disconnect.

[0088] For example, if the remote control module does not receive feedback from the central electronic module on the operating status of the ventilation module within 5 seconds after sending a seat ventilation request to the central electronic module, it will send a high-voltage lowering request to the central electronic module so that the central electronic module will respond to the high-voltage lowering request and control the relay to disconnect to complete the high-voltage power-off, thus ending this remote control.

[0089] Optionally, after the central electronic module of the remote control module sends the high voltage request, the TSP platform also sends a third failure notification, and the third failure notification indicates that the remote control failure is caused by execution timeout.

[0090] 209. The remote control module sends the operating status of the ventilation module to the terminal.

[0091] In an embodiment of the present application, the remote control module sends the operating status of the ventilation module to the terminal so that the terminal receives and displays it, so that the user can know whether the remote control is successful through the terminal.

[0092] In a possible implementation, the remote control module sends the operating status of the ventilation module to the TSP platform, and the TSP platform receives the operating status of the ventilation module and sends the operating status of the ventilation module to the terminal.

[0093] In the solution provided by the embodiment of the present application, when the remote control module receives a seat ventilation request from outside the car, it first detects the voltage of the battery. Only when the voltage of the battery is high enough, it will detect the voltage state of the car, and when the car is not in a high-voltage state, it can control the relay to close through the central electronic module to power on the high voltage of the car, and then the remote control module sends a seat ventilation request to the central electronic module, so that the central electronic module responds to the seat ventilation request and controls the operation of the ventilation module, so that the ventilation module changes the temperature or humidity of the seat surface. In this way, a method of remotely controlling the temperature or humidity of the seat in the car is realized, and the user does not need to enter the car to adjust it. In this way, the temperature or humidity of the seat surface can meet the user's satisfaction when the user sits on the seat, thereby improving the riding experience. In addition, this control method can adjust the temperature and humidity of the seat surface while ensuring the performance of the car, ensuring the safety and control accuracy of the car.

[0094] In the above Figure 2 On the basis of the shown embodiment, in the embodiment of the present application, the automobile also includes a heating module arranged in the seat; after the sub-control ventilation module is running, the method also includes: the central electronic module responds to the seat heating request, controls the ventilation module to stop running, and controls the heating module to run.

[0095] In the embodiment of the present application, the ventilation and heating functions of a single seat are mutually exclusive and cannot be turned on at the same time. The latter trigger takes priority. Therefore, when the ventilation module in the seat is running, the central electronic module receives a seat heating request for the seat, then the ventilation module is controlled to stop running and the heating module is controlled to run to ensure the control accuracy of the seat.

[0096] Optionally, the seat heating request carries a seat identification, and the central electronic module can determine whether the ventilation module in the seat indicated by the seat identification is operating based on the seat identification, and then, if the ventilation module is operating, control the ventilation module to stop operating and control the heating module to operate.

[0097] It should be noted that the central electronic module obtains the seat heating request in the same way as above. Figure 2 The manner in which the central electronic module obtains the seat ventilation request in the illustrated embodiment is similar and will not be described in detail here.

[0098] It should be noted that the above Figure 1 to Figure 2 The embodiment is explained by taking the battery voltage being greater than the threshold as an example, while in another embodiment, the voltage may be less than the threshold, and the module cannot be operated to adjust the temperature and humidity of the seat surface. That is, the method also includes: when the battery voltage is less than the threshold, the remote control module sends a first failure notification to the terminal, and the first failure notification indicates that the car cannot start the ventilation module.

[0099] In an embodiment of the present application, when the battery voltage is less than a threshold value, indicating that the battery voltage is insufficient, the ventilation module of the vehicle cannot be remotely controlled to adjust the temperature or humidity of the seat surface. Therefore, a first failure notification is sent to the terminal to indicate that the remote control has failed.

[0100] In one possible implementation, when the battery voltage is less than a threshold, the remote control module sends a first failure notification to the TSP platform; the TSP platform receives the first failure notification and sends the first failure notification to the terminal, and the first failure notification indicates that the ventilation module of the car cannot be started.

[0101] It should be noted that the above Figure 1 to Figure 2 The embodiment is explained by taking the example of the central electronic module directly controlling the relay to close in response to the high-voltage power-on request, while in another embodiment, after receiving the high-voltage power-on request, the central electronic module must successfully respond to the high-voltage power-on request within a second time period. If it fails to respond successfully within the second time period, it indicates that the power-on has failed. That is, the process of controlling the relay to close includes: the central electronic module responds to the high-voltage power-on request and controls the relay to close; when the relay is successfully controlled to close within the second time period, it is determined that the state of the vehicle is switched to the high-voltage state.

[0102] The second duration is any duration, for example, the second duration is 5 seconds.

[0103] In an embodiment of the present application, after the central electronic module receives a high-voltage power-on request, it needs to successfully respond to the high-voltage power-on request within a second time period, that is, successfully control the relay to close within the second time period so that the vehicle enters a high-voltage state within the second time period. Such a time limit is to ensure the timely response of the vehicle's electrical system to avoid affecting the normal start-up and subsequent operation of the vehicle due to too long waiting time, and it is also convenient for timely judgment of whether there is any abnormality in the power-on operation.

[0104] In one possible implementation, the relay includes a high-voltage circuit relay and a battery relay. The central electronic module controls the high-voltage circuit relay to close in response to the high-voltage power-on request, and sends a power-on request for the battery relay to the vehicle controller; the vehicle controller controls the battery relay to close in response to the power-on request for the battery relay, and when the high-voltage circuit relay is successfully controlled to close and the battery relay is successfully controlled to close within a second time period, it is determined that the state of the vehicle is switched to the high-voltage state.

[0105] In one possible implementation, if no successful response is received within the second time period, the power-on failure process includes: the central electronic module responds to the high-voltage power-on request, and if the relay is not successfully controlled to close within the second time period, the central electronic module sends a second failure notification to the remote control module, and the second failure notification indicates that the high-voltage power-on failure occurs; the remote control module sends the second failure notification to the terminal.

[0106] In an embodiment of the present application, an abnormal situation may occur in the relay. The central electronic module fails to successfully control the relay to close within the second time period in response to the high-voltage power-on request. For example, the relay fails to close. Then, a second failure notification is sent to the remote control module, so that the remote control module sends a second failure notification to the terminal.

[0107] Optionally, the relay includes a high-voltage circuit relay and a battery relay, and the central electronic module controls the high-voltage circuit relay to close in response to the high-voltage power-on request, and sends a power-on request for the battery relay to the vehicle controller; the vehicle controller controls the battery relay to close in response to the power-on request for the battery relay, and if the high-voltage circuit relay is not closed or the battery relay is not closed within a second time period, it is determined that the high-voltage power-on has failed, and a second failure notification is sent to the remote control module, the second failure notification indicating that the high-voltage power-on has failed; the remote control module sends the second failure notification to the terminal.

[0108] Optionally, the central electronic module responds to the high-voltage power-on request, and if the relay is not successfully controlled to close within the second time period, the remote control module sends the second failure notification to the TSP platform, the TSP platform receives and records the second failure notification, and sends the second failure notification to the terminal.

[0109] The second failure notification may carry an error code. For example, the error code carried by the second failure notification is “failure to increase high voltage”.

[0110] It should be noted that the above Figure 1 to Figure 2 The embodiment is explained by taking the example of the central electronic module directly controlling the relay to close in response to the high-voltage power-on request, while in another embodiment, the high-voltage power-on request needs to be verified, and the high-voltage power-on request will be responded to only after the verification is passed, that is, the car also includes: a body control module; the process of controlling the relay to close includes: the central electronic module responds to the high-voltage power-on request and sends a verification request to the body control module; the body control module responds to the verification request and verifies the high-voltage power-on request, and sends the verification result to the central electronic module; the central electronic module controls the relay to close when the verification result indicates that the verification is passed.

[0111] In an embodiment of the present application, the body control module (BCM) is used to verify the request sent by the remote control module, and only when the verification is passed, the central electronic module will respond to the request. If the request verification fails, the central electronic module will no longer respond to the request. After the central electronic module receives the high-voltage power-on request sent by the remote control module, it sends a verification request to the body control module to instruct the body control module to verify the high-voltage power-on request, and feeds back the verification result to the central electronic module. When the verification result indicates that the verification is passed, the central electronic module controls the relay to close to ensure the safety of the vehicle control.

[0112] In a possible implementation, the ventilation control request received by the remote control module carries the vehicle identification, and the high-voltage power-on request sent by the remote control module to the central electronic module based on the ventilation control request carries the vehicle identification, and the verification request includes the vehicle identification carried by the high-voltage power-on request. The body control module compares the vehicle identification recorded in the vehicle with the vehicle identification carried in the verification request, and determines that the verification is passed if the two vehicle identifications are consistent, and determines that the verification is not passed if the two vehicle identifications are inconsistent.

[0113] In an embodiment of the present application, the ventilation control request sent by the terminal to the remote control module carries a vehicle identification. The body control module responds to the detection request by comparing the vehicle identification recorded in the vehicle with the vehicle identification carried in the ventilation control request to determine whether the terminal has control authority over the vehicle, and then obtains a verification result. If the verification passes, it means that the terminal has control authority over the vehicle. If the verification fails, it means that the terminal does not have control authority over the vehicle. Only when the terminal has control authority over the vehicle will the subsequent high-voltage power-on process be executed to ensure the safety of vehicle control.

[0114] In one possible implementation, the relay includes a high-voltage circuit relay and a battery relay, and the central electronic module sends a verification request to the body control module in response to the high-voltage power-on request; the body control module verifies the high-voltage power-on request in response to the verification request, and sends the verification result to the central electronic module; when the verification result indicates that the verification has passed, the central electronic module controls the high-voltage circuit relay to close, and sends a power-on request for the battery relay to the vehicle controller; the vehicle controller controls the battery relay to close in response to the power-on request for the battery relay, and when the high-voltage circuit relay is successfully controlled to close and the battery relay is successfully controlled to close within a second time period, it is determined that the state of the vehicle is switched to the high-voltage state.

[0115] It should be noted that the above embodiment is described by taking remote control of a car as an example, while in another embodiment, the user can adjust the temperature or humidity of the seat surface through an input module in the car. That is, the control method for the seat includes: the input module responds to receiving a seat ventilation command, and when the car is in a high-voltage state, the seat ventilation command is sent to the central electronic module; the central electronic module responds to the seat ventilation command, and when the car is in a high-voltage state and the battery voltage is greater than a threshold, controls the operation of the ventilation module.

[0116] In an embodiment of the present application, the car also includes an input module, which is any type of input module, for example, the input module is a voice input module or an electronic screen, and the user can input control instructions through the voice input module in the car, or the user can trigger an operation on the electronic screen by clicking on the electronic screen or through other buttons in the car to input control instructions.

[0117] In an embodiment of the present application, a user inputs a seat ventilation command through an input module in the car, and the input module can obtain the seat ventilation command, and when the car is in a high-pressure state, the seat ventilation command can be directly sent to the central electronic module.

[0118] Optionally, the input module can receive the seat ventilation command only when the vehicle is in a high pressure state.

[0119] In the embodiment of the present application, when the car is in a low voltage state, the battery can only power some components, but cannot power the input module. Therefore, the input module cannot be used at this time, and the input module cannot receive instructions. When the car is in a high voltage state, the power battery can power the input module, and the input module is started and can obtain instructions.

[0120] In an embodiment of the present application, when the car is in a high voltage state and the battery voltage is greater than a threshold value, it means that the ventilation module can be controlled to operate, and the ventilation module is controlled to operate to adjust the temperature or humidity of the seat surface.

[0121] It should be noted that the process of the central electronic module controlling the operation of the ventilation module in response to the seat ventilation command is the same as the process of the central electronic module controlling the operation of the ventilation module in the above embodiment and will not be repeated here.

[0122] Based on the above-mentioned embodiments, the present application also provides a flow chart that can be controlled based on an input model, such as Figure 3 and Figure 4 shown.

[0123] exist Figure 3In the instrument cluster control module, ICC (Instrument Cluster Control) is equivalent to the input module.

[0124] CEM can provide the voltage status of the car. When the car is in a low voltage state, ICC cannot control the car's screen display and the seat ventilation function is turned off.

[0125] When the car is in a low voltage state, the ICC determines whether the car power gear is switched to ON. When the car power gear is switched to ON, it means that the car is in a high voltage state, and the car screen can display. The user can trigger the seat ventilation operation for the ventilation module through the car screen. In response to the seat ventilation operation, the ICC sends a seat ventilation instruction to the CEM.

[0126] CEM can obtain the working mode of DCDC through CMDC. When receiving the seat ventilation command, it determines the voltage mode of the car, whether the vehicle power gear is ON, whether the seat ventilation command for gear 1 / 2 / 3 is received, whether the battery voltage is greater than the threshold, and whether the working mode of DCDC is ON. When the vehicle voltage mode, the vehicle power gear is ON, the seat ventilation command for gear 1 / 2 / 3 is received, the battery voltage is greater than the threshold, and the working mode of DCDC is ON, CEM responds to the seat ventilation command and controls the ventilation module in the seat to execute the corresponding gear ventilation mode; and returns the operating status of the ventilation module to ICC. The ICC module can receive the operating status and highlight the operating gear of the ventilation module on the car screen. Afterwards, CEM determines whether the low-voltage mode is switched to OFF, whether DCDC stops working, whether the gear position of the ventilation module is set to 0, whether the heating function of the seat is turned on, and whether the battery voltage is lower than the threshold; when the low-voltage mode is switched to OFF, or, when DCDC stops working, or, when the gear position of the ventilation module is set to 0, or, when the heating function of the seat is turned on, or, when the battery voltage is lower than the threshold, the seat ventilation function is turned off, that is, the ventilation module is stopped.

[0127] In the embodiment of the present application, the gear position of the ventilation module is 0, which means that the ventilation module is in neutral, that is, the ventilation module stops running.

[0128] exist Figure 4In the system, MIC (Microphone) and ICC are equivalent to input modules. After MIC detects voice, it sends voice to ICC, and ICC sends ventilation control instructions to CEM through voice. CEM responds to the ventilation control instruction, combines the working mode of DCDC obtained from CMDC, controls the operation of the ventilation module in the seat indicated by the ventilation control instruction, and feeds back the operating status of the ventilation module to ICC.

[0129] In an embodiment of the present application, if the vehicle has a voice control function, the seat ventilation function can be controlled by voice. When the seat ventilation is turned on by voice, the default gear is 2nd gear, and voice supports gear adjustment. In addition, the function options of the seat ventilation function are displayed on the screen of the car, such as switch options or gear adjustment options. The user can turn on or off the seat ventilation function and adjust the gear of the seat ventilation function by triggering the function options on the screen. In addition, the screen displays the ventilation gear corresponding to the seat with the seat ventilation function turned on. Only one function option corresponding to each seat is displayed on the screen, and the function option is used to turn on or off the ventilation function of the corresponding seat. The user can turn on the seat ventilation function through the function option corresponding to any seat on the screen, and click the function option multiple times to switch the ventilation gear or turn off the seat ventilation function. For example, the gear shift order is 0→3→2→1→0 each time you click.

[0130] It should be noted that the process of CEM controlling the operation of the ventilation module in response to the ventilation control instruction is the same as the above Figure 3 The process shown is the same and will not be repeated here.

[0131] It should be noted that the above-mentioned multiple optional embodiments can be combined in any manner and will not be described in detail here.

[0132] Based on the embodiment shown above, the embodiment of the present application also provides a process for controlling the seat ventilation function in Yuncheng, which includes the following steps 1 to step 1.

[0133] Step 1: The user initiates a remote control command through the mobile phone APP.

[0134] Step 2: After receiving the control command sent by the mobile phone, the TSP platform sends the control command to TBOX.

[0135] Step 3: TBOX first determines the precondition: hard-line judgment: the battery voltage is greater than 11.5V; for the dormant remote control scenario, consider adding a precondition SOC timeout 3 seconds judgment to determine whether the battery voltage is greater than 11.5V within more than 3 seconds.

[0136] In the embodiment of the present application, the prerequisites (preconditions) of the seat ventilation function are: vehicle power gear = ON, DC-DC is in working state, and the voltage of the low-voltage battery is greater than the threshold. If the preconditions are not met, the remote control command will not be executed this time, TBOX will feedback the failure reason to the TSP platform, and the TSP platform will feedback the failure reason to the mobile phone APP.

[0137] Step 4: If the precondition is passed, TBOX determines the high voltage status of the vehicle and the power-on status of the IGN2 relay; if the vehicle is high voltage, go directly to step 6; if the vehicle is not high voltage, pull the high voltage first; that is, T-BOX sends TBOX_RemotePowerOnOff=01 (send 5 frames continuously) to CEM. CEM receives TBOX_RemotePowerOnOff=01, and BCM verifies TBOX_RemotePowerOnOff=01 and sends the verification result to CEM.

[0138] Among them, TBOX_RemotePowerOnOff=01 is equivalent to high voltage power-on request. IGN2 relay is equivalent to high voltage circuit relay.

[0139] Step 5. When the verification result indicates that the verification has passed, the CEM responds to TBOX_RemotePowerOnOff=01, closes the IGN2 relay to power the entire vehicle, and sends a command to the VCU to control the VCU to close the positive and negative relays of the battery. In this process, the high-voltage power-on is considered successful only if the maximum delay is 5 seconds and the IGN2 relay is closed and the positive and negative relays of the battery are closed; otherwise, the high-voltage power-on is considered to have failed. If the high-voltage power-on fails, the CEM will feedback the failure notification to the TBOX, and the TBOX will report the failure notification to the TSP, and the CEM will execute the high-voltage process to disconnect the closed relay and report the TSP error code "failed to power on high voltage".

[0140] In the embodiment of the present application, if the BCM returns a verification failure, the corresponding error code (authentication failure) is reported to the TSP through the CEM and TBOX.

[0141] Step 6: After the vehicle is high-voltage, TBOX sends TBOX_RemoteSeatHeatVent_Driver (driver seat ventilation and heating request) or TBOX_RemoteSeatHeatVent_Psn (passenger seat ventilation and heating request) (5 consecutive frames) in the CAN bus to CEM to control seat ventilation.

[0142] Step 7. After receiving TBOX_RemoteSeatHeatVent_Driver or TBOX_RemoteSeatHeatVent_Psn, CEM controls the corresponding ventilation module to operate for seat ventilation, and feeds back SCM_SeatHeatVentSetSts_Drive (driver seat ventilation gear status feedback) or SCM_SeatHeatVentSetSts_Psngr (passenger seat ventilation gear status feedback) to TBOX, which then feeds back to the TSP platform.

[0143] In the embodiment of the present application, if the CEM does not return or feedback the status within the timeout (5s), the TBOX sends a high voltage reduction request to the CEM so that the CEM executes the high voltage reduction process, and the TBOX reports the execution timeout to the TSP platform.

[0144] Step 8: The TSP platform processes the signal value reported by TBOX and feeds back the remote vehicle operation execution result to the APP.

[0145] For example, the seat ventilation function includes four gears: 0 / 1 / 2 / 3. When the gear is 0, it means that the seat ventilation function is off, that is, the ventilation module stops running; when the gear is 1 / 2 / 3, it means that the seat ventilation function is on, that is, the ventilation module is running, but the adjustment of the temperature or humidity of the seat surface is not strong enough. In the hot summer, users can turn on the main / passenger seat ventilation function through the large screen to achieve seat ventilation and cooling, improving the user's driving experience.

[0146] Regarding the contents shown in the above embodiments, in the embodiments of the present application, Table 1 is used to show under what circumstances the seat ventilation function of the car can be turned on and under what circumstances the seat ventilation function will be turned off.

[0147] Table 1

[0148]

[0149] Among them, OFF is used to indicate off, ON is used to indicate on, IGN1 is used to indicate low-voltage circuit relays, IGN2 is used to indicate high-voltage circuit relays, KL15 is a power signal, and the KL15 power-on source refers to the source that provides power to the KL15 circuit to keep it in the power-on state. KEY (key) is used to indicate high-voltage power-on through the car key; REMOTE (remote control) is used to indicate high-voltage power-on through remote control, and OTA (over-the-air download technology) is used to indicate high-voltage power-on in the case of vehicle software updates and configurations.

[0150] In the embodiment of the present application, the seat ventilation function has no memory function. After the vehicle is powered on with high voltage, the seat ventilation function is turned on. If the vehicle is powered on with high voltage, the seat ventilation function is turned off. When the vehicle is powered on with high voltage again, the seat ventilation function remains turned off. In addition, the seat ventilation function and the seat heating function of the same seat are mutually exclusive and cannot be turned on at the same time. The function that is triggered later will be kept first.
