[0122] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0123] Reference Figure 1 As shown, the present application provides a vehicle refrigerator control system 100 , including: a vehicle controller 110 and a communication network 120 .

[0124] The vehicle refrigerator 200 controlled by the control system 100 of the present application includes at least one refrigerator function device 210. The refrigerator function device 210 is used to realize the function of the vehicle refrigerator 200.

[0125] The vehicle controller 110 is at least used to implement control of the vehicle 1 .

[0126] Reference Figures 1 to 3 As shown, the vehicle controller 110 includes at least one refrigerator domain control module 111. The vehicle controller 110 is at least used to realize the logical control of the refrigerator functional device 210. The vehicle controller 110 with the refrigerator domain control module 111 can be connected with the refrigerator functional device 210 through a hard line 122, that is, an electrical connection through a PCB board and a cable. At this time, when the refrigerator domain control module 111 runs the corresponding control program, the vehicle controller 110 can send a command signal to the refrigerator functional device 210 and receive a feedback signal from the refrigerator functional device 210; the vehicle controller 110 forms a signal transmission with the refrigerator functional device 210 through the communication network 120 so that the refrigerator domain control module 111 sends a command signal to the refrigerator functional device 210.

[0127] In some embodiments of the present application, reference Figure 1 As shown, the communication network 120 may include a bus 121 and / or a hard line 122. The bus 121 may be a CAN / CANFD bus 121 or a LIN bus 121.

[0128] In some embodiments of the present application, the communication method adopted by the communication network 120 includes at least one of CAN / CANFD signal communication, LIN signal communication and hard-wire signal communication.

[0129] The vehicle controller 110 is at least used to implement vehicle 1 control, such as body function control, that is, the vehicle controller 110 can be configured as a body domain controller, which can implement functions of body-related functional units, such as opening or closing doors and windows, etc. Of course, the vehicle controller 110 can also be configured as a cabin domain controller to control multimedia, air conditioning and other functions.

[0130] That is, in the present application, the vehicle 1 may have a plurality of vehicle controllers 110 , but not all of the vehicle controllers 110 are used to control the vehicle refrigerator 200 .

[0131] Reference Figure 2 and Figure 3 As shown, the vehicle controller 110 may be a vehicle domain controller 110 b , or the vehicle controller 110 may be a central controller 110 a of the vehicle.

[0132] In the technical solution of the present application, the vehicle domain controller 110b refers to a domain controller (DCU, Domain Controller Unit), and the vehicle control unit 140 of the present application refers to an electronic controller (ECU, Electronic Control Unit).

[0133] The vehicle domain controller 110b is used to implement functional control based on "domains", that is, the vehicle electronic system is decomposed into several functional blocks according to the functions, and the domain controller takes the lead in building the system architecture inside different functional blocks, and uses multi-core CPU / GPU chips with stronger processing power to relatively centrally control each domain. Based on a simple understanding, DCU can be understood as a central processing unit that implements a program.

[0134] As an optional solution, the vehicle domain controller 110b can be divided into: power domain, chassis domain, cockpit domain, auxiliary driving domain, body domain, etc. according to specific control functions.

[0135] As an optional solution, the vehicle domain controller 110b can also be divided into: a front domain, a rear domain, a left domain, and a right domain according to the parts of the vehicle 1 that are controlled.

[0136] Reference Figures 1 to 3 As shown, at least one refrigerator domain control module 111 may be integrated in a vehicle domain controller 110b. The refrigerator domain control module 111 of the present application is a virtual function module composed of the physical circuit of the vehicle domain controller 110b and the executable program stored therein.

[0137] For the purpose of centralized control, the refrigerator domain control modules 111 of all vehicle refrigerators 200 of the vehicle 1 may be centralized in one vehicle domain controller 110 b.

[0138] Based on the purpose of local control, the refrigerator domain control module 111 can also be set in different domain control modules.

[0139] In some embodiments of the present application, the control system 100 may include at least one vehicle control unit 140. The vehicle control unit 140 is used to implement logical control of functional units of the vehicle 1.

[0140] In the technical solution of the present application, the vehicle control unit 140 is an electronic control unit that realizes a certain function or some functions of the vehicle. Like an ordinary computer, it is composed of a microcontroller (MCU), memory (ROM, RAM), input / output interface (I / O), analog-to-digital converter (A / D) and driver and other large-scale integrated circuits. Based on a simple understanding, the ECU can be understood as a single-chip microcomputer that realizes independent functions.

[0141] In some embodiments of the present application, the vehicle control unit 140 may be an ESP (Electronic Stability Program) controller or an IPB (Intelligent Power Brake) controller, etc.

[0142] In some embodiments of the present application, one of the vehicle control units 140 is constructed as a compressor ECU, and the compressor ECU is used to control an on-board compressor, and the on-board compressor is used to compress the refrigerant of the on-board refrigerator 200.

[0143] The refrigerator domain control module 111 of the vehicle domain controller 110b interacts with the compressor ECU via the communication network 120 so that the refrigerator domain control module 111 of the vehicle domain controller 110b controls the vehicle compressor by sending a command signal to the compressor ECU. The compressor ECU can also be linked with the air conditioning control of the vehicle 1.

[0144] That is, the refrigerator domain control module 111 of the vehicle domain controller 110b can also send control instructions to other vehicle control units 140 through the communication network 120 so that these vehicle control units 140 cooperate with the refrigerator control or provide corresponding decision data for the refrigerator control.

[0145] As one of the applications, the refrigerator domain control module 111 of the vehicle domain controller 110b can send a control instruction to the compressor ECU to achieve temperature control of the vehicle refrigerator 200; the IPB controller can feedback the vehicle speed data to the refrigerator domain control module 111 of the vehicle domain controller 110b, so that the refrigerator domain control module 111 of the vehicle domain controller 110b can determine whether the fan speed can be increased to enhance the cooling effect, because the vehicle speed data can reflect the power condition of the vehicle 1 on the one hand, and on the other hand, when the vehicle speed is high, the driving noise is high, so that the user will not pay too much attention to the noise caused by the fan.

[0146] Reference Figures 2 to 8 As shown, in order to realize the control chain of person-vehicle-refrigerator, the control system 100 may further include an in-vehicle multimedia 130, which serves as an input port of the control chain.

[0147] The vehicle multimedia 130 is used to realize the multimedia functions of the vehicle 1 and / or provide a human-computer interaction interface; wherein the vehicle domain controller 110b forms a signal transmission with the vehicle multimedia 130 through the communication network 120 so that the user can form a human-computer interaction with the refrigerator domain control module 111 through the vehicle multimedia 130. The vehicle multimedia 130 can be a touch screen used by the vehicle computer.

[0148] As an optional solution, the vehicle refrigerator 200 can also be controlled through voice control or AI interaction mode, that is, data is exchanged with the refrigerator domain control module 111 by voice control.

[0149] As an optional solution, users can also remotely control the car refrigerator through remote interaction with the car computer through mobile terminals such as mobile phones, such as remote scheduling to open the refrigerator, or keep the car refrigerator in working condition when the vehicle is in parked state, such as running in ECO mode (economic mode) to ensure that there is no power outage when storing important items such as medicines in the car refrigerator, and users can also learn about the operating status of the car refrigerator through their mobile phones.

[0150] In some embodiments, reference Figure 7 As shown, the vehicle 1 is provided with two vehicle refrigerators 200: a front row refrigerator and a rear row refrigerator ( Figure 7 ), a front refrigerator (car refrigerator 1) is arranged between the two front seats, and a rear refrigerator (car refrigerator 2) is arranged between the two rear seats.

[0151] As an optional solution, the vehicle controller serving as the cabin domain controller may control the vehicle refrigerator 200 and the vehicle multimedia 130 in the front row, and the vehicle controller serving as the body domain controller may control the refrigerator in the rear row.

[0152] Alternatively, the vehicle controller as the body domain controller may control both the front refrigerator and the rear refrigerator, while the vehicle controller as the cabin domain controller may only control the in-vehicle multimedia 130. Figures 2 to 4 As shown, the front refrigerator and the rear refrigerator are independently controlled by two refrigerator domain control modules 111 in the vehicle controller.

[0153] As an alternative, two different vehicle controllers may be provided: a first vehicle controller and a second vehicle controller.

[0154] The first vehicle controller (cockpit domain) controls the vehicle multimedia 130, and the second vehicle controller (body domain) includes a refrigerator domain control module 111 to control the vehicle refrigerator 200. The advantage of adopting such a solution is that the second vehicle controller (body domain) that is most linked with the vehicle refrigerator 200 can complete data interaction and logic operations within the controller, that is, reasonable arrangement of computing power (the computing power burden of the cockpit domain is greater) and reduced use of the bus 121 in signal transmission.

[0155] As a specific solution, the following control method can be used to realize the control of the vehicle refrigerator 200 based on the vehicle multimedia 130; the control method includes:

[0156] S101: Setting relevant functional parameters of the vehicle refrigerator 200 through the human-computer interaction portal provided by the vehicle multimedia 130.

[0157] S102: After receiving the setting information, the refrigerator domain control module 111 performs logical calculation and judgment in combination with the vehicle information, and sends the specific control instructions of the vehicle refrigerator 200 to the refrigerator function device 210 and the vehicle control unit 140, so that the vehicle refrigerator 200 operates according to the established mode.

[0158] Reference Figure 8 As shown, in some embodiments of the present application, the touch screen of the vehicle multimedia 130 provides an operation interface of the vehicle refrigerator 200, that is, an operation interface of the control system 100 of the present application. The user can select the corresponding vehicle refrigerator 200 (when there are multiple vehicle refrigerators 200) through the operation interface, and then set and operate the refrigerator mode, temperature, function, etc.

[0159] Reference Fig. 9 As shown, in some embodiments of the present application, an independent control panel 230 may be provided at the vehicle refrigerator 200, so that the user can set and operate the refrigerator through the independent control panel 230. Figure 7 The control panel 230 shown is provided with operation buttons such as switch, cooling, temperature adjustment, heating and drawer ejection, and a display interface of refrigerator temperature. The control panel 230 can form a direct signal interaction with the vehicle domain controller 110b.

[0162] Specifically, the heating film device 211 includes: a heating film power supply 211a and a heating film 211b. The heating film 211b can convert electrical energy into thermal energy to achieve the heating function of the vehicle refrigerator 200; the heating film power supply 211a is used to supply power to the heating film 211b of the vehicle refrigerator 200. The heating control unit 111a is used to control the heating film power supply 211a.

[0163] The fan device 212 includes: a fan drive circuit 212a and a fan motor 212b. The fan motor 212b is used to drive the fan of the vehicle refrigerator 200. The fan drive circuit 212a is used to drive the fan motor. The fan drive circuit 212a has a plurality of semiconductor switches for driving. The fan speed can be controlled by adjusting the duty cycle of the drive signal driving the semiconductor switch. The fan control unit 111b is used to control the fan drive circuit 212a.

[0164] The lighting device 213 includes: a lighting power supply 213a and a lighting lamp 213b. The lighting power supply 213a is used to power a lighting lamp 213b of the vehicle refrigerator 200; the lighting lamp 213b is used to illuminate the interior of the vehicle refrigerator 200. Of course, in some cases, the lighting lamp 213b can also illuminate the area near the vehicle refrigerator 200. The lighting control unit 111c is used to control the lighting power supply 213a.

[0165] The germicidal lamp device 214 includes a germicidal lamp power supply 214a and a germicidal lamp 214b. The germicidal lamp power supply 214a is used to power the germicidal lamp 214b of the vehicle refrigerator 200; the germicidal lamp 214b is used to illuminate the interior of the vehicle refrigerator 200 and achieve a sterilization effect through a special spectrum. The sterilization control unit 111d is used to control the germicidal lamp power supply 214a.

[0166] The expansion valve device 215 includes: an expansion valve drive circuit 215a and an electronic expansion valve 215b. The expansion valve drive circuit 215a is used to drive the electronic expansion valve 215b of the vehicle refrigerator 200; the electronic expansion valve 215b is used as a throttling element for the refrigerant of the vehicle refrigerator 200. The expansion valve control unit 111e is used to control the expansion valve drive circuit 215a.

[0167] The electric control drawer 220 includes a sliding drive circuit 220a and a sliding motor 220b. The sliding motor 220b is used to drive the sliding of the drawer of the vehicle refrigerator 200; the sliding drive circuit 220a is used to drive the sliding motor 220b. The drawer control unit 111j is used to control the driving signal of the sliding drive circuit 220a and / or receive the feedback signal of the sliding motor 220b.

[0168] The fan and the electronic expansion valve 215b are combined with the vehicle compressor in the vehicle air conditioning system to realize the refrigeration function of the refrigerator. The vehicle refrigerator 200 may also have an independent compressor to realize the refrigeration function. As an optional solution, the vehicle 1 may be provided with more than two vehicle refrigerators 200, and the refrigerant used by these vehicle refrigerators 200 may come from the same refrigerant pipeline, and further may be compressed and pressurized by the same vehicle compressor.

[0169] As a specific solution, the heating film power supply 211a is used to power the heating film 211b, and the power of the heating film power supply 211a can be adjusted to control whether the heating film 211b is working and the heating temperature. The heating film power supply 211a can provide a 12V DC power supply. The power can be controlled by the duty cycle of the semiconductor switch in the heating film power supply 211a.

[0170] The control principle of the lighting lamp power supply 213a and the germicidal lamp power supply 214a is similar to that of the heating film power supply 211a, and is mainly to control the power of the lighting lamp 213b and the germicidal lamp 214b.

[0171] The expansion valve driving circuit 215a and the sliding driving circuit 220a both control the duty ratio of the semiconductor switches therein.

[0172] The sliding motor 220b serves as an actuator for the pull-out drawer, and a stepping motor or other motor that can precisely control displacement may be used.
