[0056] The embodiment of the present invention provides a method for controlling vehicle temperature. Figure 1 As shown, Figure 1 It is a flow chart of the first embodiment of the vehicle temperature control method of the present invention.

[0057] Here, exemplary embodiments are described in detail, and examples thereof 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.

[0058] It should be noted that, in this embodiment, the vehicle temperature control method of the present application is applied to the upper control module, and is specifically executed by the upper controller in the upper control module, and the upper controller establishes communication connections with the power domain controller and the multimedia interactive system respectively, and the power domain controller establishes communication connections with the multimedia interactive system. At this time, the vehicle temperature control method of the present application includes the following steps:

[0059] The vehicle temperature control method of the present invention comprises:

[0060] Step S10: when the first gear of the vehicle is in a discharging state (i.e., drawing power from the vehicle end), obtaining a vehicle power-drawing signal uploaded by the multimedia interactive system, and determining a request for loading enable signal of the loading controller according to the vehicle power-drawing signal;

[0061] In this embodiment, refer to Figure 2 , Figure 2 This is a first gear discharge-upload vehicle power supply temperature control flow chart. When the first gear of the vehicle is in the discharge state, the vehicle power supply signal uploaded by the multimedia interaction system is obtained through the communication connection between the upload controller and the multimedia interaction system. After the vehicle power supply signal is determined, the upload enable signal of the upload controller can be obtained.

[0062] It should be noted that the first gear can be understood as the ON gear of the vehicle, and can be understood as the gear position in which the entire vehicle is powered on, that is, power is supplied to all electrical devices of the vehicle.

[0063] The upper body controller can be represented by RCU (Refrigeration Control Unit); the power domain controller can be represented by PMS (Powertrain Management System); and the multimedia interactive system can be represented by MMI (Multi Media Interface).

[0064] In addition, it should be noted that the vehicle power signal can be understood as being obtained by the multimedia interaction system after detecting that the vehicle power button is triggered through a preset human-computer interaction interface, wherein the preset human-computer interaction interface can be understood as the interaction interface of the multimedia interaction system.

[0065] Step S20: transmitting the request for loading enable signal to the power domain controller, so that the power domain controller can obtain a loading enable permission signal according to the request for loading enable signal and the vehicle power acquisition signal after receiving the vehicle power acquisition signal uploaded by the multimedia interactive system;

[0066] In this embodiment, refer to Figure 2, through the connection between the bodywork controller and the power domain controller, the bodywork controller's request bodywork enable signal is transmitted to the power domain controller. In this way, the power domain controller can obtain the bodywork enable permission signal according to the request bodywork enable signal and the vehicle power collection signal after receiving the vehicle power collection signal uploaded by the multimedia interaction system.

[0067] Step S30: reading the upload enable permission signal, and performing a high-voltage power-on operation according to the upload enable permission signal to determine an upload high-voltage power-on completion signal of the upload controller;

[0068] In this embodiment, refer to Figure 2 After the power domain controller transmits the upper installation enable permission signal to the upper installation controller through the connection between the power domain controller and the upper installation controller, the upper installation enable permission signal is read, and then the high-voltage power-on operation is performed according to the upper installation enable permission signal. After the upper installation controller completes the high-voltage power-on operation, the upper installation high-voltage power-on completion signal of the upper installation controller can be determined.

[0069] For example, refer to Figure 3 , Figure 3 This is the upper control block diagram of the vehicle temperature control of the present invention. After determining that the upper controller receives the upper enable permission signal, the upper pre-charge relay is closed first, then the upper main positive relay is closed, and finally the upper pre-charge relay is disconnected, that is, the high voltage power-on operation is performed according to the upper enable permission signal.

[0070] Step S40: transmitting the upper-mounted high-voltage power-on completion signal to the multimedia interactive system so that the multimedia interactive system can set the target vehicle temperature;

[0071] In this embodiment, refer to Figure 2 After determining the upper body high voltage power-on completion signal of the upper body controller, the upper body high voltage power-on completion signal is transmitted to the multimedia interaction system through the communication connection between the multimedia interaction system and the upper body controller. In this way, the multimedia interaction system can set the target vehicle temperature of the vehicle after receiving the upper body high voltage power-on completion signal uploaded by the upper body controller.

[0072] It should be noted that the target vehicle temperature can be understood as the temperature of the upper compartment of the vehicle.

[0073] Step S50: reading the target vehicle temperature, and adjusting the temperature of the upper compartment of the vehicle according to the target vehicle temperature.

[0074] In this embodiment, refer to Figure 2, through the communication connection between the multimedia interaction system and the upper body controller, the target vehicle temperature uploaded by the multimedia interaction system is read, and then the working status of the vehicle is determined, and whether the temperature of the vehicle is within the threshold range of the target vehicle temperature is judged according to the working status; if the temperature of the vehicle is not within the threshold range of the target vehicle temperature, the temperature of the upper body box is adjusted to the threshold range of the target vehicle temperature to obtain a temperature setting success signal of the upper body controller; then, through the connection between the upper body controller and the multimedia interaction system, the temperature setting success signal is fed back to the multimedia interaction system, and the adjusted upper body box temperature and the working status of the vehicle are transmitted to the multimedia interaction system in real time.

[0075] In summary, in this embodiment, the present application adds a body control module, which includes a body controller, and the body controller establishes communication connections with the power domain controller and the multimedia interaction system respectively, and the power domain controller and the multimedia interaction system establish communication connections. The vehicle temperature control method of the present application is applied to the body control module. When the first gear of the vehicle is in a discharging state, according to the communication connection between the upper-mounted controller and the multimedia interaction system, the vehicle power-taking signal uploaded by the multimedia interaction system is obtained, and the upper-mounted enable signal requesting the upper-mounted controller is determined according to the vehicle power-taking signal; the upper-mounted enable signal requesting is then transmitted to the power domain controller, so that the power domain controller obtains the upper-mounted enable permission signal according to the upper-mounted enable signal requesting and the vehicle power-taking signal after receiving the vehicle power-taking signal uploaded by the multimedia interaction system; then, according to the communication connection between the upper-mounted controller and the power domain controller, the upper-mounted enable permission signal uploaded by the power domain controller is read, and a high-voltage power-on operation is performed according to the upper-mounted enable permission signal to determine the upper-mounted high-voltage power-on completion signal of the upper-mounted controller; and the upper-mounted high-voltage power-on completion signal is transmitted to the multimedia interaction system through the connection between the upper-mounted controller and the multimedia interaction system, so that the multimedia interaction system can set the target vehicle temperature; then, the target vehicle temperature uploaded by the multimedia interaction system is read, and the temperature of the upper-mounted box of the vehicle is regulated according to the target vehicle temperature.

[0076] Different from the traditional vehicle temperature control method, the present application establishes communication connections between the added upper body control module and the power domain controller and the multimedia interaction system respectively. In other words, the upper body control module is integrated into the vehicle's overall control, and the temperature of the vehicle's upper body box is set and displayed through the multimedia interaction system, thereby solving the problem that the rear-mounted control panel (i.e., the temperature controller and display panel) appears very abruptly in the cab, making the cab unsightly. In addition, the present application avoids driving safety issues caused by loose fixation of the rear-mounted control panel while ensuring coordination between the upper body control module and the entire vehicle, and saves manufacturing costs.

[0077] Furthermore, based on the first embodiment of the vehicle temperature control of the present invention, a second embodiment of the vehicle temperature control of the present invention is proposed.

[0078] In this embodiment, the upper-mounted control module further includes an upper-mounted pre-charging relay and an upper-mounted main positive relay. The above step S30: performing a high-voltage power-on operation according to the upper-mounted enable signal may also include the following implementation steps.

[0079] Step S301: closing the upper loading pre-charging relay according to the upper loading enabling signal, and detecting whether the upper loading main positive relay meets the preset power-on condition through the upper loading pre-charging relay;

[0080] In this embodiment, refer to Figure 2 or Figure 3 , through the connection between the power domain controller and the upper load controller, after receiving the upper load enable permission signal uploaded by the power domain controller, the upper load pre-charging relay is closed first according to the upper load enable permission signal, and the upper load pre-charging relay is used to detect whether the upper load main positive relay meets the preset power-on condition.

[0081] It should be noted that the preset power-on condition can be customized according to the needs of the user, and can be understood as the condition for the upper body main positive relay to be turned on, that is, the condition for the upper body main positive relay to be closed.

[0082] Step S302: If the upper mounted main positive relay reaches the preset power-on condition, the upper mounted main positive relay is closed, and the upper mounted pre-charging relay is disconnected after a preset extended time.

[0083] In this embodiment, if the upper mounted main positive relay reaches the preset power-on condition, the upper mounted main positive relay is closed, and the upper mounted pre-charging relay is disconnected after the preset extended time.

[0084] It should be noted that the preset extension time can also be customized according to user needs.

[0085] In addition, it should be noted that the upper-mounted pre-charge relay is used to protect the upper-mounted main positive relay and prevent the upper-mounted main positive relay from directly contacting the instantaneous current after power-on. Excessive instantaneous current can easily cause contact erosion of the upper-mounted main positive relay. In other words, the upper-mounted pre-charge relay is used to reduce the current introduced into the upper-mounted main positive relay.

[0086] For example, after the upper main positive relay is confirmed, the upper pre-charge relay will be disconnected after a delay of 200ms.

[0087] In yet another embodiment, referring to Figure 3In the pre-charging circuit, an upper-mounted pre-charging resistor is connected between the upper-mounted main positive relay and the upper-mounted pre-charging relay. The upper-mounted pre-charging resistor is used to effectively protect the upper-mounted main positive relay to prevent the upper-mounted main positive relay from being damaged due to excessive instantaneous current at the moment of direct power-on. In other words, the upper-mounted pre-charging resistor plays a current limiting role in the pre-charging circuit.

[0088] The temperature of the upper body of the vehicle is regulated according to the target vehicle temperature, and the following implementation steps may also be included.

[0089] Step S501: determining the working state of the vehicle, and judging whether the temperature of the vehicle is within a threshold range of the target vehicle temperature according to the working state;

[0090] In this embodiment, the working state of the vehicle is first determined, and then it is determined whether the temperature of the upper body box is within a threshold range of the target vehicle temperature according to the working state.

[0091] It should be noted that the working state can be understood as the state in which the vehicle is working on the upper body box, including but not limited to the state of air conditioning heating, air conditioning cooling or air conditioning air supply.

[0092] Step S502: If not, adjusting the temperature of the upper body box to within the threshold range of the target vehicle temperature to obtain a temperature setting success signal of the upper body controller;

[0093] In this embodiment, if in the current working state of the vehicle, after receiving information that the temperature of the upper body box is not within the threshold range of the target vehicle temperature, the temperature of the upper body box is then adjusted to within the threshold range of the target vehicle temperature, and then a temperature setting success signal of the upper body controller can be obtained.

[0094] Step S503: Feedback the temperature setting success signal to the multimedia interactive system, and transmit the adjusted upper compartment temperature and the working status of the vehicle to the multimedia interactive system in real time.

[0095] In this embodiment, refer to Figure 2 Through the connection between the multimedia interaction system and the bodywork controller, the temperature setting success signal is fed back to the multimedia interaction system, and the regulated bodywork box temperature and the working status of the vehicle are uploaded to the multimedia interaction system in real time.

[0096] Furthermore, the present invention also provides a vehicle temperature control method, which is also applied to a body control module and is specifically executed by a body controller in the body control module, and may also include the following implementation steps.

[0097] Step A10: when the first gear is in a charging state, or the second gear of the vehicle is in a charging and discharging state, detecting whether the vehicle is connected to the mains;

[0098] In this embodiment, refer to Figure 4 , Figure 4 It is a temperature control flow chart of the second gear charging and discharging or the first gear charging-uploading mains power supply. When the first gear is in the charging state or the second gear of the vehicle is in the charging and discharging state (ie, taking power from the mains terminal), it is detected whether the vehicle is connected to the mains.

[0099] It should be noted that the second gear of the vehicle can be understood as the OFF gear of the vehicle.

[0100] Step A20: If the vehicle is connected to the mains, the step of transmitting the upper installation enable signal to the power domain controller is stopped, and the preset upper installation first gear relay is closed;

[0101] In this embodiment, if the vehicle is connected to the mains, the step of transmitting the request for the upper installation enable signal to the power domain controller is stopped, and the preset upper installation first gear relay is closed.

[0102] For example, refer to Figure 3 When the bodywork DC\DC outputs 12V to wake up the bodywork controller (RCU), the bodywork controller will close the bodywork first gear relay (bodywork ON gear relay), that is, the lead-acid battery power 12V / 24V loaded in the vehicle is output as ON gear to the relevant controllers of the whole vehicle (such as power domain controller (PMS), multimedia interaction system (MMI)), etc.

[0103] It should be noted that after the first-gear relay of the upper body is closed, it is used to wake up the PMS and MMI. After the PMS and MMI are woken up, they are executed according to "ON gear vehicle discharge: draw power from the vehicle end".

[0104] In yet another embodiment, referring to Figure 3 When the AC power plug is unplugged, the upper DCDC stops outputting, the "upper ON gear relay" is disconnected, the ON gear wake-up disappears, and the upper controller stops working.

[0105] Step A30: transmitting the voltage data of the mains to the power domain controller;

[0106] In this embodiment, the preset RCU power supply relay is closed to connect the communication connection between the power domain controller and the upper body controller, and the voltage data of the mains power is uploaded to the power domain controller to wake up the power domain controller for operation.

[0107] Step A40: after receiving the upper installation work shut-off signal from the power domain controller, transmitting the voltage data to the multimedia interactive system;

[0108] In this embodiment, after receiving the upper body operation shutdown signal from the power domain controller through the communication connection between the power domain controller and the upper body controller, the voltage data of the mains power is transmitted to the multimedia interaction system through the communication connection between the multimedia interaction system and the upper body controller to wake up the multimedia interaction system to work. In this way, the multimedia interaction system will display the mains power supply status on the preset human-computer interaction interface and set the target vehicle temperature through the preset human-computer interaction interface.

[0109] Step A50: Return to the step of reading the target vehicle temperature and adjusting the temperature of the upper body of the vehicle according to the target vehicle temperature.

[0110] In this embodiment, through the communication connection between the multimedia interaction system and the upper body controller, after the voltage data of the AC power is transmitted to the multimedia interaction system so that the multimedia interaction system sets the target vehicle temperature according to the voltage data, the step returns to execute the step of reading the target vehicle temperature and regulating the temperature of the upper body box of the vehicle according to the target vehicle temperature.

[0111] Furthermore, the present invention also provides a vehicle temperature control method, which is applied to a multimedia interactive system, the multimedia interactive system establishes communication connections with the power domain controller and the upper body controller respectively, and the power domain controller and the upper body controller establish communication connections.

[0112] The vehicle temperature control method of the present invention may further include the following implementation steps:

[0113] Step B10: when the first gear of the vehicle is in a discharging state, determining a vehicle power supply signal of the vehicle according to the button power supply information of the vehicle;

[0114] In this embodiment, when the first gear of the vehicle is in a discharging state, the multimedia interaction system determines the vehicle power supply signal of the vehicle according to the button power supply information of the vehicle.

[0115] For example, when the multimedia interaction system detects that the vehicle's power-collecting button is pressed, it obtains the vehicle's button power-collecting information, and then determines the vehicle's power-collecting signal based on the vehicle's button power-collecting information.

[0116] Step B20: transmitting the vehicle power supply signal to the upper-mounted controller, so that the upper-mounted controller determines a request upper-mounted enable signal according to the vehicle power supply signal and sends the request upper-mounted enable signal to the power domain controller;

[0117] In this embodiment, the vehicle power supply signal is transmitted to the upper-mounted controller through the connection between the multimedia interactive system and the upper-mounted controller. In this way, after receiving the vehicle power supply signal, the upper-mounted controller can determine the upper-mounted enable signal according to the vehicle power supply signal, and send the upper-mounted enable signal to the power domain controller through the connection between the upper-mounted controller and the power domain controller.

[0118] Step B30: transmitting the vehicle power supply signal to the power domain controller, so that the power domain controller determines the upper installation enable permission signal according to the vehicle power supply signal and the upper installation enable request signal and sends the upper installation enable permission signal to the upper installation controller;

[0119] In this embodiment, the vehicle power-taking signal is transmitted to the power domain controller through the connection between the multimedia interactive system and the power domain controller. In this way, after receiving the vehicle power-taking signal, the power domain controller can determine the upper installation enable permission signal according to the vehicle power-taking signal and the upper installation enable request signal, and send the upper installation enable permission signal to the upper installation controller through the connection between the upper installation controller and the power domain controller.

[0120] Step B40: receiving a high-voltage power-on completion signal uploaded by the upper-mount controller, wherein the high-voltage power-on completion signal is obtained by the upper-mount controller performing a high-voltage power-on operation according to the upper-mount enable signal;

[0121] In this embodiment, the multimedia interactive system is connected to the upper body controller to receive the upper body high voltage power-on completion signal uploaded by the upper body controller.

[0122] It should be noted that the upper load high voltage power-on completion signal is obtained by the upper load controller performing a high voltage power-on operation according to the upper load enable permission signal.

[0123] Step B50: transmitting a preset target vehicle temperature to the upper body controller so that the upper body controller can adjust the temperature of the upper body box of the vehicle according to the target vehicle temperature.

[0124] In this embodiment, after the multimedia interactive system detects the information for setting the target vehicle temperature on the preset human-machine interactive interface, it will set the target vehicle temperature through the preset human-machine interactive interface, and transmit the target vehicle temperature to the upper-mounted controller according to the connection between the multimedia interactive system and the upper-mounted controller. In this way, after receiving the target vehicle temperature, the upper-mounted controller can first determine the working state of the vehicle, and then determine whether the temperature of the upper-mounted box is within the threshold range of the target vehicle temperature according to the working state. If, in the current working state of the vehicle, after receiving the information that the temperature of the upper-mounted box is not within the threshold range of the target vehicle temperature, the temperature of the upper-mounted box is adjusted to within the threshold range of the target vehicle temperature, and then the temperature setting success signal of the upper-mounted controller can be obtained, and then the temperature setting success signal is fed back to the multimedia interactive system through the connection between the multimedia interactive system and the upper-mounted controller, and the adjusted upper-mounted box temperature and the working state of the vehicle are uploaded to the multimedia interactive system in real time.

[0125] Furthermore, the present invention also provides a vehicle temperature control method, which is also applied to a multimedia interactive system. The vehicle temperature control method may further include the following implementation steps:

[0126] Step C10: when the first gear is in a charging state, or the second gear of the vehicle is in a charging and discharging state, receiving the voltage data of the mains power uploaded by the upper body controller, wherein the voltage data is obtained by the upper body controller according to the upper body work shutdown signal after receiving the upper body work shutdown signal uploaded by the power domain controller;

[0127] In this embodiment, when the first gear is in a charging state or the second gear of the vehicle is in a charging and discharging state, the voltage data of the AC power uploaded by the upper-mounted controller is received through the connection between the multimedia interaction system and the upper-mounted controller.

[0128] It should be noted that the voltage data can be understood as being obtained through the communication connection between the bodywork controller and the power domain controller, after the bodywork controller receives the bodywork work shutdown signal uploaded by the power domain controller, through the connection between the multimedia interaction system and the bodywork controller according to the bodywork work shutdown signal.

[0129] Step C20: the upper installation work shutdown signal is obtained by the power domain controller reading the voltage data uploaded by the upper installation controller after the upper installation controller fails to receive the upper installation enable signal.

[0130] In this embodiment, the upper installation work shutdown signal can be understood as that, through the connection between the power domain controller and the upper installation controller, the power domain controller will read the voltage data uploaded by the upper installation controller after not receiving the request upper installation enable signal uploaded by the upper installation controller, and obtain it based on the voltage data.

[0131] Step C30: Return to the step of setting the target vehicle temperature through the preset human-computer interaction interface.

[0132] In this embodiment, after receiving the AC power voltage data uploaded by the upper-mounted controller through the connection between the multimedia interaction system and the upper-mounted controller, the multimedia interaction system will display the AC power supply status through a preset human-computer interaction interface, and then return to execute the step of setting the target vehicle temperature through the preset human-computer interaction interface.

[0133] Furthermore, the present invention also provides a vehicle temperature control method, which is applied to a power domain controller, the power domain controller establishes communication connections with the multimedia interaction system and the upper body controller respectively, the multimedia interaction system establishes communication connections with the upper body controller, and the vehicle temperature control method may also include the following implementation steps:

[0134] Step D10: reading the vehicle power supply signal uploaded by the multimedia interactive system, and obtaining a request for an onboard enable signal, wherein the onboard enable signal is determined by the onboard controller according to the vehicle power supply signal uploaded by the multimedia interactive system;

[0135] In this embodiment, through the communication connection between the power domain controller and the multimedia interaction system, the vehicle power supply signal uploaded by the multimedia interaction system is read, and after receiving the vehicle power supply signal uploaded by the multimedia interaction system, a request for loading enable signal is obtained.

[0136] It should be noted that the upper-mounted enable signal can be understood as the upper-mounted controller receiving the vehicle power supply signal uploaded by the multimedia interaction system based on the communication connection between the upper-mounted controller and the multimedia interaction system. After receiving the vehicle power supply signal, the upper-mounted controller obtains the vehicle power supply signal.

[0137] Step D20: determining a body installation enabling permission signal according to the vehicle power supply signal and the body installation enabling signal;

[0138] In this embodiment, after receiving the vehicle power-on signal and the upper installation enable signal, the power domain controller determines the upper installation enable permission signal according to the vehicle power-on signal and the upper installation enable signal.

[0139] Step D30: Transmitting the upper installation enable permission signal to the upper installation controller, so that the upper installation controller performs a high voltage power-on operation according to the upper installation enable permission signal and regulates the temperature of the upper installation box of the vehicle according to the target vehicle temperature uploaded by the multimedia interactive system.

[0140] In this embodiment, the upper body enabling permission signal is transmitted to the upper body controller through the communication connection between the power domain controller and the upper body controller. In this way, after receiving the upper body enabling permission signal uploaded by the power domain controller to perform the high voltage power-on operation, the upper body controller can receive the target vehicle temperature uploaded by the multimedia interactive system according to the communication connection with the multimedia interactive system, and adjust the temperature of the upper body box of the vehicle according to the target vehicle temperature.

[0141] In summary, on the one hand, the present invention discharges the vehicle in the ON gear (i.e., draws power from the vehicle end), obtains the button power-drawing information (i.e., draws power from the mains) in the multimedia interaction system (MMI), and the multimedia interaction system determines the vehicle power-drawing signal according to the button power-drawing information (i.e., the mains power-drawing function is turned on), and sends the vehicle power-drawing signal to the power domain controller (PMS) and the upper body controller (RCU). When the RCU detects that there is no fault, it sends a request upper body enable signal to the PMS. When the PMS detects that the upper body function activation conditions are met, the upper body enable permission signal is sent to the RCU. Then the RCU performs the high-voltage power-on operation, and after completing the high-voltage power-on operation, the upper body high-voltage power-on completion signal is sent to the MMI. After receiving the upper body high-voltage power-on completion signal, the MMI will set the target vehicle temperature and transmit the target vehicle temperature to the upper body controller, and after receiving the temperature setting success signal of the upper body controller, the temperature inside the upper body box is displayed. On the other hand, the present invention is in the OFF gear for vehicle discharge and charging, and the ON gear for vehicle charging (i.e., drawing power from the mains). When the upper-mounted DC\DC outputs 12V to wake up the upper-mounted controller (RCU), the upper-mounted controller will close the upper-mounted first gear relay (upper-mounted ON gear relay), that is, the lead-acid battery electricity 12V / 24V loaded on the vehicle is output as the ON gear to the relevant controllers of the whole vehicle (such as PMS, MMI), etc., and then, the PMS and MMI are awakened, and the temperature of the upper-mounted box is regulated according to the vehicle discharge state in the ON gear. Thereby, the requirement of the upper-mounted box of the vehicle working in the OFF gear is realized without changing the original vehicle control strategy and vehicle hardware, and the cost of the upper-mounted box is effectively saved. In addition, the technical solution of the present application has good compatibility, is not limited by the voltage platform of the vehicle, and can be adapted to all upper-mounted boxes.
