[0022] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0023] The present application provides a method for controlling the seat temperature of a vehicle. Figure 1 , which shows a schematic diagram of the implementation environment of the method provided in the embodiment of the present application. The implementation environment may include: a VCU (Vehicle Control Unit) 11, a seat controller 12, a first battery 13, a thermoelectric material 14, a temperature sensor 15, a voltage sensor 16, a DCDC (Direct Current to Direct Current) controller 17, a power battery 18, a second battery 19, a BMS (Battery Management System) 20, an ECU (Electronic Control Unit) 21, a user terminal 22, and a radiator 23.

[0024] For example, the VCU 11 can obtain the vehicle's power-on and power-off status through the ECU 21. When the vehicle is powered off, the VCU 11, through the seat controller 12, detects the temperature of the thermoelectric material 14 via a temperature sensor 15 installed near the thermoelectric material 14. In response to the temperature of the thermoelectric material 14 exceeding a temperature threshold, the VCU 11, through the seat controller 12, obtains the voltage value of the first battery 13 from a voltage sensor 16 installed near the first battery 13. Based on the voltage value of the first battery 13, the VCU 11 determines the remaining charge of the first battery 13. When the temperature of the thermoelectric material 14 exceeds the temperature threshold, the thermoelectric material 14 converts the seat's thermal energy into electrical energy and transmits it to the first battery 13.

[0025] Optionally, in response to the remaining power of the first battery 13 being greater than a first power threshold, the VCU11 controls the seat controller 12 to send a request to the DCDC controller 17 to allow charging, and obtains the safety inspection result of the power battery 18 through the DCDC controller 17; the VCU11 obtains the remaining power of the power battery 18 from the BMS20.

[0026] In one possible implementation, if the remaining charge of the power battery 18 is less than or equal to a second charge threshold and the safety check result of the power battery 18 indicates that the power battery 18 is in a safe state, the detection result indicating that the power battery 18 is allowed to be charged is determined. In response to the detection result indicating that the power battery 18 is allowed to be charged, the VCU 11 controls the current of the first battery 13 through the seat controller 12 to be transmitted to the power battery 18 via the DCDC controller 17, thereby charging the power battery 18.

[0027] Optionally, in response to the detection result indicating that the power battery charging is permitted, the VCU 11 controls the seat controller 12 to send a request to the DCDC controller 17 to allow charging, and obtains the safety check result of the second battery 19 through the DCDC controller 17; the VCU 11 obtains the remaining charge of the second battery 19 from the BMS 20. If the remaining charge of the second battery 19 is less than or equal to the fifth charge threshold, and the safety check result of the second battery 19 indicates that the second battery 19 is in a safe state, it is determined that the detection result indicating that the second battery charging is permitted indicates that the second battery 19 is permitted to be charged. The VCU 11 controls the current of the first battery 13 through the seat controller 12 to be transmitted to the second battery 19 through the DCDC controller 17, thereby charging the second battery 19.

[0028] Exemplarily, in response to the detection result indicating that the second battery 19 is not allowed to be charged, the VCU 11 controls the first battery 13 to supply power to the radiator 23 through the seat controller 12, and remotely prompts the user through the user terminal 22. In response to the remaining power of the first battery 13 being less than or equal to a third power threshold, the VCU 11 controls the first battery 13 to stop external charging through the seat controller 12, wherein the third power threshold is less than the first power threshold. In response to the vehicle being powered on, the remaining power of the first battery 13 being greater than a fourth power threshold, or the temperature of the thermoelectric material 14 being less than or equal to the temperature threshold minus a preset temperature value, the VCU 11 controls the first battery 13 to disconnect electrically from the thermoelectric material 14 through the seat controller 12, and remotely prompts the user through the user terminal 22.

[0029] In one possible implementation, VCU11 monitors the charging status of the vehicle through BMS20. If it is detected that the vehicle is in an external charging state, VCU11 controls the thermoelectric material 14 to stop working through the seat controller 12, controls the first battery 13 to stop external charging through BMS20, and remotely prompts the user through the user terminal 22.

[0030] Among them, communication connections may be established between the VCU11, the seat controller 12, the first battery 13, the thermoelectric material 14, the temperature sensor 15, the voltage sensor 16, the DCDC controller 17, the power battery 18, the second battery 19, the BMS20, the ECU21, the user terminal 22 and the radiator 23 through a wired or wireless network, and in addition to the user terminal 22, circuits are also set between these devices on the vehicle as needed, and switching devices are arranged on the circuits, so that the electrical connections between them can be controlled according to operational requirements.

[0031] Based on the above Figure 1 In the implementation environment shown, the present application embodiment provides a method for controlling the seat temperature of a vehicle. Figure 2 As shown, taking the method applied to a VCU as an example, the method includes steps 201 to 204.

[0032] In step 201 , when the vehicle is powered off, the VCU obtains the temperature of a thermoelectric material located on a backrest and a seat cushion of a vehicle seat.

[0033] For example, the backrest and cushion of each seat in the vehicle are covered with a flexible thermoelectric material. The flexible thermoelectric material can be a nanocomposite material with a carbon nanotube or graphene substrate and other thermoelectrically active components. Alternatively, a single block of thermoelectric material can be installed for rows of seats within the vehicle. After installation, each block of thermoelectric material is electrically connected to a first battery, which temporarily stores the electrical energy converted by the thermoelectric material.

[0034] In one possible implementation, the VCU can obtain the vehicle's power-on and power-off status from the ECU (Electronic Control Unit) via the CAN bus. This status includes both power-on and power-off. When the vehicle is powered off, the VCU obtains the temperature of the thermoelectric material, including: The VCU 11 uses the seat controller to detect the temperature of the thermoelectric material from a temperature sensor installed near the thermoelectric material. For example, the temperature sensor is installed near each piece of thermoelectric material to detect the temperature of each piece.

[0035] In step 202 , in response to the temperature of the thermoelectric material being greater than a temperature threshold, the VCU obtains the remaining power of the first battery, wherein when the temperature of the thermoelectric material is greater than the temperature threshold, the thermoelectric material converts the thermal energy of the seat into electrical energy and transmits it to the first battery.

[0036] Exemplarily, after determining the temperature of the thermoelectric material, the temperature of the thermoelectric material is compared with a temperature threshold. If the temperature of the thermoelectric material is greater than the temperature threshold, the VCU obtains the remaining charge of the first battery, including: the VCU detects the voltage of the first battery from a voltage sensor installed near the first battery via the seat controller, and then determines the remaining charge of the first battery based on the voltage of the first battery. Optionally, the voltage sensor is installed near the first battery to detect the voltage of the first battery.

[0037] In one possible implementation, when the temperature of the thermoelectric material exceeds a temperature threshold, the thermoelectric material converts the seat's thermal energy into electrical energy. The VCU transmits the electrical energy generated by the thermoelectric material to the first battery via the seat controller. Optionally, the temperature threshold may be determined based on the type of thermoelectric material.

[0038] In step 203 , in response to the remaining power of the first storage battery being greater than a first power threshold, the VCU obtains a detection result of whether power battery charging is allowed, where the detection result of whether power battery charging is allowed is used to indicate whether the power battery is allowed to be charged.

[0039] For example, after obtaining the remaining charge of the first battery, the remaining charge of the first battery is compared with a first charge threshold. If the remaining charge of the first battery is greater than the first charge threshold, the VCU obtains a detection result indicating that charging of the power battery is permitted. The detection result indicating that charging of the power battery is permitted is used to indicate whether charging of the power battery is permitted. Optionally, the first charge threshold can be set based on experience, for example, the first charge threshold can be 80%.

[0040] In one possible implementation, the VCU obtains a detection result indicating that power battery charging is allowed, including: controlling the DCDC to obtain a safety check result of the power battery, where the safety check result of the power battery is used to indicate whether the power battery is in a safe state; obtaining the remaining power of the power battery; in response to the remaining power of the power battery being less than or equal to a second power threshold and the power battery safety check result indicating that the power battery is in a safe state, the detection result indicating that power battery charging is allowed indicates that the power battery is allowed to be charged.

[0041] Exemplarily, the VCU obtains a detection result indicating that charging of the power battery is permitted through the seat controller. Optionally, the seat controller sends a request for permission to charge to the DCDC controller via the CAN bus. After receiving the request for permission to charge from the seat controller, the DCDC controller obtains a safety check result for the power battery, where the safety check result indicates whether the power battery is in a safe state.

[0042] In one possible implementation, after determining the power battery safety check result, obtaining the remaining power battery charge includes: the VCU obtaining the remaining power battery charge from the BMS via the CAN bus. Optionally, after obtaining the remaining power battery charge, the remaining power battery charge is compared with a second power threshold. If the remaining power battery charge is less than or equal to the second power threshold and the power battery safety check result indicates that the power battery is in a safe state, determining that the power battery charge is permitted indicates that the power battery charge is permitted. Optionally, the second power threshold charge can be set based on experience.

[0043] Exemplarily, if the remaining power of the power battery is greater than the second power threshold, or the safety check result of the power battery indicates that the power battery is not in a safe state, the detection result of determining that power battery charging is allowed indicates that the power battery is not allowed to be charged.

[0044] In step 204 , in response to the detection result of the power battery charging permission indicating that the power battery is allowed to be charged, the VCU controls the first storage battery to charge the power battery of the vehicle.

[0045] Exemplarily, after determining the detection result that the power battery charging is allowed, if the detection result that the power battery charging is allowed indicates that the power battery is allowed to be charged, the VCU controls the first battery to charge the power battery of the vehicle, including: the VCU controls the current of the first battery through the seat controller to be transmitted to the power battery through the DCDC controller to charge the power battery.

[0046] In one possible implementation, in response to a detection result indicating that the power battery is not allowed to be charged, a detection result indicating that the second battery is allowed to be charged is obtained, and the detection result indicating that the second battery is allowed to be charged is used to indicate whether the second battery is allowed to be charged; in response to a detection result indicating that the second battery is allowed to be charged, the first battery is controlled to charge the second battery.

[0047] Optionally, the second battery is a battery provided by the vehicle. Obtaining a detection result indicating that charging of the second battery is permitted includes: controlling the DC / DC converter to obtain a safety check result of the second battery, the safety check result of the second battery being used to indicate whether the second battery is in a safe state; obtaining a remaining charge of the second battery; and, in response to the remaining charge of the second battery being less than or equal to a fifth charge threshold and the safety check result of the second battery indicating that the second battery is in a safe state, indicating that charging of the second battery is permitted.

[0048] Exemplarily, the VCU obtains a detection result indicating that charging of the second battery is permitted through the seat controller. Optionally, the seat controller sends a message requesting permission to charge to the DCDC controller via the CAN bus. After receiving the message requesting permission to charge from the seat controller, the DCDC controller obtains a safety check result for the second battery, wherein the safety check result for the second battery indicates whether the second battery is in a safe state.

[0049] In one possible implementation, after determining the safety check result of the second battery, obtaining the remaining charge of the second battery includes: the VCU obtaining the remaining charge of the second battery from the BMS via the CAN bus. Optionally, after completing the acquisition of the remaining charge of the second battery, the remaining charge of the second battery is compared with a fifth charge threshold. If the remaining charge of the second battery is less than or equal to the fifth charge threshold, and the safety check result of the second battery indicates that the second battery is in a safe state, determining that the second battery is allowed to charge indicates that the second battery is allowed to charge. Optionally, the fifth charge threshold can be set based on experience.

[0050] Optionally, after determining the detection result that the second battery charging is allowed, if the detection result that the second battery charging is allowed indicates that the second battery is allowed to be charged, the VCU controls the first battery to charge the second battery, including: the VCU controls the current of the first battery through the seat controller to be transmitted to the second battery through the DCDC controller to charge the second battery.

[0051] In one possible implementation, in response to a detection result indicating that the second battery is allowed to charge, the VCU controls the first battery to supply power to the heat sink. This includes: the VCU controls the first battery to supply power to the radiator via a seat controller, and remotely notifies a user via a user terminal that the first battery is supplying power to the heat sink. The heat sink is located outside the vehicle body, electrically connected to the first battery, and configured to convert electrical energy into heat and release it externally.

[0052] Exemplarily, during external charging of the first battery, the VCU continuously monitors the remaining charge of the first battery and compares the remaining charge of the first battery with a third charge threshold. In response to the remaining charge of the first battery being less than or equal to the third charge threshold, the VCU controls the first battery to stop external charging, including: the VCU controls the first battery to stop external charging via the seat controller. Optionally, the third charge threshold can be set based on experience and needs to be less than the first charge threshold. For example, it can be set to 15% or 20%.

[0053] Optionally, after the thermoelectric material starts working, the VCU continuously monitors the vehicle's power-on and power-off status, the remaining power of the first battery, and the temperature of the thermoelectric material, and compares the remaining power of the first battery with a fourth power threshold. In response to the vehicle being powered on, the remaining power of the first battery is greater than the fourth power threshold, or the temperature of the thermoelectric material is less than or equal to the temperature threshold minus a preset temperature value, the VCU controls the first battery to be electrically disconnected from the thermoelectric material, including: the VCU controls the first battery to be electrically disconnected from the thermoelectric material through the seat controller. The VCU can also remotely prompt the user through the user terminal to disconnect the first battery from the thermoelectric material. Exemplarily, the fourth power threshold can be set based on experience, and it is required to satisfy that the fourth power threshold is greater than the first power threshold.

[0054] In one possible implementation, in response to the vehicle being in an external charging state, the thermoelectric material is controlled to stop operating, and the first battery is controlled to stop external charging. For example, the VCU monitors the vehicle's charging status through the BMS. If it detects that the vehicle is in an external charging state, the VCU controls the thermoelectric material to stop operating through the seat controller and controls the first battery to stop external charging through the BMS. The VCU can also remotely notify the user through a user terminal that the vehicle is in an external charging state and the thermoelectric material has stopped operating.

[0055] In an embodiment of the present application, when the vehicle is powered off, the temperature of thermoelectric materials located on the backrest and seat cushion of the vehicle's seat is obtained, and if the temperature of the thermoelectric material is greater than a temperature threshold, the remaining power of the first battery is obtained, wherein when the temperature of the thermoelectric material is greater than the temperature threshold, the thermoelectric material converts the thermal energy of the seat into electrical energy and transmits it to the first battery for temporarily storing the electrical energy generated by the thermoelectric material; in response to the remaining power of the first battery being greater than the first power threshold, indicating that the remaining power of the first battery is high, a detection result of power battery charging permission is obtained to facilitate judgment on whether the power battery allows the first battery to be charged; in response to the detection result of power battery charging permission indicating that the power battery allows charging, the first battery is controlled to charge the power battery of the vehicle, thereby reducing the temperature of the vehicle's seat, thereby improving the riding experience, avoiding the generation of harmful gases due to high seat temperature, and ensuring the health of passengers.
