[0044] Figure 7 This is a block diagram illustrating a vehicle according to an exemplary embodiment. Detailed Implementation

[0045] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0046] Before detailing the specific embodiments of this disclosure, the application scenario of this disclosure is first described below. This disclosure can be used for the control process of a vehicle refrigerator. The vehicle refrigerator can be a refrigerator including a cold storage heat exchanger. The cold storage heat exchanger can include a cold storage module and a heat exchanger module. The cold storage module uses a phase change cold storage material, which can store or release cold energy. For example, it can store cold energy when the refrigerator compressor is working and release cold energy when the compressor stops working to maintain a stable internal temperature of the refrigerator. In related technologies, the control of the vehicle refrigerator is not linked to the vehicle's driving conditions. Therefore, when the vehicle's power battery is low or the power supply to the power equipment is insufficient, the vehicle refrigerator still operates at a high frequency, consuming too much power, which is detrimental to improving the vehicle's range.

[0047] To address the aforementioned technical issues, this disclosure provides a control method, device, storage medium, program product, and vehicle for an in-vehicle refrigerator. The control method acquires vehicle driving information and adjusts the operating state of the in-vehicle refrigerator based on the driving information. This enables the refrigerator control to be linked with the vehicle's driving conditions, effectively preventing the in-vehicle refrigerator's energy consumption from affecting the vehicle's range, thereby further enhancing the driving experience for vehicle users.

[0048] The specific embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0049] Figure 1 This is a flowchart illustrating an exemplary embodiment of a vehicle-mounted refrigerator control method. The control method can be used with a refrigerator controller or a vehicle controller. The vehicle-mounted refrigerator includes at least a heat exchanger assembly and an inner liner. The heat exchanger assembly is configured to exchange heat with a storage cavity within the inner liner. The heat exchanger assembly includes a cold storage heat exchanger, which comprises a cold storage module and a heat exchanger module. The cold storage heat exchanger is connected to a compressor. The structure of the vehicle-mounted refrigerator can be as follows: Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a vehicle-mounted refrigerator according to an exemplary embodiment of the present disclosure. The vehicle-mounted refrigerator includes a refrigerator top cover 101, a refrigerator inner liner 102, a refrigerator bottom plate 103, a refrigerator direct cooling heat exchanger 203, an external direct cooling heat exchanger inlet 201, an external direct cooling heat exchanger outlet 202; a refrigerator aerogel insulation layer 3, a refrigerator internal cold storage heat exchanger 4, a cold storage heat exchanger refrigerant inlet 401 and a refrigerant outlet 402. Valves can be respectively provided at the external direct cooling heat exchanger inlet 201 and the cold storage heat exchanger refrigerant inlet 401 to control the inflow of refrigerant. When refrigerant flows into the refrigerator direct cooling heat exchanger 203, the refrigerator direct cooling heat exchanger 203 can generate cooling capacity. When refrigerant flows into the cold storage heat exchanger 4, the cold storage heat exchanger 4 can store cooling capacity, or it can store and release cooling capacity simultaneously. Figure 1 As shown, the method may include:

[0050] S1, obtain vehicle driving information.

[0051] The driving information includes at least one of road condition information and vehicle status information; the road condition information includes at least one of road congestion and road terrain information; and / or, the vehicle status information includes vehicle speed.

[0052] Optionally, the road condition information may also include the target distance to the traffic light and the braking status of the vehicle in front, and the road terrain information may include the road gradient.

[0053] In some implementations, the road congestion status may include the road being congested. The road can be determined to be congested if the vehicle's speed during the current sampling time period meets a preset congestion condition or if the vehicle's current travel segment is a navigation congested segment. The preset congestion condition may include at least one of the following: the average vehicle speed during the current sampling time period is less than a first speed threshold; the target duration during the current sampling time period where the speed is continuously less than a second speed threshold is greater than a first preset duration threshold; the number of stops within a specified duration is greater than a preset number threshold; and the duration of a single stop is greater than a second preset duration threshold.

[0054] In other embodiments, the vehicle's acceleration or deceleration state can be determined based on the vehicle's average acceleration during the current sampling time period. For example, if the average acceleration during the current sampling time period is greater than a first preset acceleration threshold, the vehicle is in an acceleration state; if the average acceleration during the current sampling time period is less than a second preset acceleration threshold, the vehicle is in a deceleration state. The first preset acceleration threshold is greater than the second preset acceleration threshold; for example, the first preset acceleration threshold could be 0.3g, and the second preset acceleration threshold could be -0.3g.

[0055] In some embodiments, if the target distance is less than a preset distance threshold or the vehicle in front is braking, it can be determined that the vehicle is in a deceleration state.

[0056] In some other embodiments, when the slope of the road is greater than a first preset slope threshold, the vehicle travels on an uphill road; when the slope of the road is less than a second preset slope threshold, the vehicle travels on a downhill road, wherein the first preset slope threshold is greater than or equal to the second preset slope threshold.

[0057] In some embodiments, the vehicle is in a normal driving state if the average vehicle speed during the current sampling time period is greater than the third speed threshold.

[0058] S2, adjust the working status of the vehicle refrigerator according to the driving information.

[0059] In this step, when it is determined that the driving information meets the first condition, the working state of the vehicle refrigerator is adjusted to the first state; when it is determined that the driving information meets the second condition, the working state of the vehicle refrigerator is adjusted to the second state.

[0060] The first condition includes one or more of the following: the road is congested, the vehicle is accelerating, or the vehicle is traveling uphill. In this first state, the heat exchanger module stops circulating refrigerant with the thermal management system, and the cold storage module provides insulation or cooling for the storage cavity.

[0061] The second condition includes one or more of the following: the vehicle is in normal driving condition, the vehicle is in deceleration condition, and the vehicle is traveling on a downhill road. In this second state, refrigerant flows between the heat exchanger module and the thermal management system, the heat exchanger module releases cold energy into the storage cavity, and the cold storage module absorbs and stores cold energy from the heat exchanger module.

[0062] Optionally, the cold storage module includes a phase change cold storage material, which can store or release cold energy. In the first state, the heat exchange module can release the cold energy stored in the cold storage module to the storage cavity. In the second state, the cold storage module absorbs and stores cold energy from the heat exchange module.

[0063] The above technical solutions can effectively adjust the working state of the vehicle refrigerator according to the vehicle's driving information, providing reliable technical support for the linkage control of the vehicle refrigerator and driving conditions. This can effectively improve the reliability of the vehicle refrigerator's energy-saving control and further prevent the vehicle's range from being affected by the vehicle refrigerator's energy consumption.

[0064] Optionally, the heat exchange assembly further includes a direct cooling heat exchanger, which is connected in parallel with the cold storage heat exchanger. In the first state, the direct cooling heat exchanger stops circulating refrigerant with the thermal management system.

[0065] For example, such as Figure 3 As shown, Figure 3 This is a schematic diagram of a vehicle refrigerator refrigeration system according to an exemplary embodiment of the present disclosure. The direct cooling heat exchanger can be connected in parallel with the cold storage heat exchanger. The direct cooling heat exchanger can be provided with a refrigerant inflow valve and a cold energy release valve. When the refrigerant inflow valve is opened, the refrigerant can flow into the cold storage heat exchanger to generate cold energy when the compressor is running. When the cold energy release valve is open, the cold energy generated by the cold storage heat exchanger can be released to reduce the temperature inside the refrigerator. When the cold energy release valve is closed, the cold energy generated by the cold storage heat exchanger is stored.

[0066] Optionally, in the first state, the compressor of the vehicle refrigerator stops running or runs at a first preset frequency, and the cold storage heat exchanger enters a cold release state, wherein the first preset frequency is within a first preset frequency range. In the second state, the compressor of the vehicle refrigerator can run at a second frequency, which is within a second preset frequency range, and the lower limit of the second preset frequency range is greater than the upper limit of the first preset frequency range.

[0067] Optionally, if it is determined that the cold storage heat exchanger includes a cold energy release valve, the cold energy release valve of the cold storage heat exchanger can be opened to allow the cold storage heat exchanger to enter the cold energy release state; if it is determined that the cold storage heat exchanger is a condenser whose cold energy release cannot be actively controlled, the cold storage heat exchanger will continuously release cold energy when there is stored cold energy.

[0068] The above technical solution, by adjusting the working state of the vehicle refrigerator according to the vehicle's driving information, can provide reliable technical support for the linkage control between the vehicle refrigerator and the driving conditions, thereby effectively avoiding the situation where the energy consumption of the vehicle refrigerator affects the vehicle's range, and further improving the driving experience of vehicle users.

[0078] Optionally, the second condition includes one or more of the following: the vehicle is in a normal driving state, the vehicle is in a decelerating state, and the vehicle is traveling on a downhill road.

[0087] Step 501: Obtain the current remaining power of the vehicle's power battery.

[0088] Step 502: Determine whether the remaining power is less than a preset power threshold.

[0089] In this step, if it is determined that the remaining power is less than the preset power threshold, step 503 is executed; if it is determined that the remaining power is greater than or equal to the preset power threshold, step 501 is executed again.

[0090] For example, the preset battery threshold can be 60%, 65%, or 70%, etc. Taking 70% as an example, that is, when the SOC (State of Charge, remaining battery) is less than 70%, step 503 is executed.

[0091] Step 503: Obtain vehicle driving information.

[0092] Step 504: Adjust the working status of the vehicle refrigerator according to the driving information.
