Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more particularly to a vehicle thermal management method and apparatus, a vehicle, electronic equipment, and a storage medium. Background Technology

[0002] In the thermal management solutions of related technologies, a set of thermal management systems that can meet the heating and cooling needs of the passenger compartment and / or battery is adapted to a vehicle model. The thermal management system is configured with a refrigerant circuit suitable for the vehicle model, that is, the composition of each valve body in the basic unit combination is preset.

[0003] During thermal management control, software controls each valve in the refrigerant circuit based on the heating and cooling requirements of the passenger compartment and / or battery. The valve combinations in the refrigerant circuit are standardized for each vehicle model, with separate refrigerant circuits for the battery, the passenger compartment, and both the battery and passenger compartment.

[0004] When the cabin requires cooling, a unique refrigerant circuit is determined based on the cabin's cooling requirements. If a valve in this unique refrigerant circuit is unavailable, any refrigerant circuit created based on that unavailable valve will also be unavailable. Since the refrigerant circuits are fixed and the selection of fixed refrigerant circuits is limited, unavailable refrigerant circuits cannot meet the cooling and heating requirements of the cabin and / or battery.

[0099] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0100] The following description, with reference to the accompanying drawings, outlines a vehicle thermal management method and apparatus, a vehicle, an electronic device, and a storage medium according to embodiments of the present disclosure.

[0101] Figure 1 This is a schematic flowchart of a vehicle thermal management method provided in an embodiment of the present disclosure.

[0102] like Figure 1 As shown, the method includes the following steps:

[0103] Step 101: Obtain at least two preset refrigerant circuits that can meet the thermal management request, and determine the desired opening degree of the valve body in each refrigerant circuit. Each refrigerant circuit includes at least one valve body. The thermal management request includes a battery thermal management request and / or a cabin thermal management request.

[0104] To meet user requirements, the refrigerant circuit may contain multiple refrigerant circuits or a combination of two refrigerant circuits to satisfy the control commands. The refrigerant circuit also includes the actual opening degree of the valve body and the sensor, including whether the valve body is currently in a fault state, such as: the current working state of the compressor (working / not working), the current working speed, and whether it is in a fault state (whether it is adjustable); the current opening degree of the electronic regulating valve (fully open / half open) and whether it is in a fault state (whether it is adjustable).

[0105] In some embodiments of this disclosure, the refrigerant circuit includes valve bodies and sensors. The valve bodies and sensors in the refrigerant circuit include: EDC (electric compressor), SOV1 (refrigerant shut-off valve), SOV2, SOV3, SOV4, ERV1 (electronic regulating valve), ERV2, EXV1 (electronic expansion valve), EXV2, EXV3, PT1 (temperature and pressure sensor), PT2, PT3, T1 (temperature sensor), T2, P1 (pressure sensor), and P2. It should be noted that this disclosure uses an example with 17 valve bodies and sensors, but this description does not constitute a limitation on the type, number, or desired opening degree of the first valve body and first sensor. This application does not limit the type or number of valve bodies and sensors.

[0106] Step 102: In response to the battery / cabin thermal management request, determine a first refrigerant circuit combination that satisfies the battery thermal management request, and determine a second refrigerant circuit combination that satisfies the cabin thermal management request.

[0107] The thermal management request is a certain adjustment mode determined by the vehicle system. For example, the sensor detects the battery temperature, and when the battery temperature is too high, it sends a signal. The vehicle system uses this signal to determine that a cooling mode needs to be used for adjustment.

[0108] After the vehicle's infotainment system determines which thermal management request is being used based on sensor signals, a pre-defined mapping relationship is established between these sensor signals and the refrigerant mode request. For example, a humidity signal corresponds to a dehumidification refrigerant mode request, while a heat pump or PTC signal corresponds to a heating refrigerant mode request. This mapping relationship needs to be set according to the actual situation, specifically based on the actual hardware layout and the number of refrigerant mode request types the vehicle can fulfill. This determines how many quantities can be detected by sensors, converted into corresponding signals, and then a mapping relationship is established between these signal types and the thermal management request types. Through this mapping relationship, when the vehicle's infotainment system receives a signal, it only needs to iterate through the mapping relationship to determine the refrigerant mode request. This embodiment of the disclosure does not limit the specific method for determining the thermal management request.

[0109] Step 103: Determine whether the actual opening degree of the valve body in the first refrigerant circuit combination and the second refrigerant circuit combination can be adjusted to the desired opening degree.

[0110] Based on the actual opening degree of the valve body, determine whether the desired opening degree of the valve body can be achieved. For example: if the desired opening degree of EXV1 in the valve body is half open, the actual opening degree is fully open, no fault has occurred, and it is in an adjustable state, then it is determined that the current EXV can meet the requirements; if the desired opening degree of SOV1 in the valve body is open, the actual opening degree is closed, and a fault has occurred, making it unadjustable, then it is determined that SOV1 cannot meet the requirements; if the desired opening degree of EXV2 in the valve body is fully open, the actual opening degree is fully open, and a fault has occurred, then it is determined that the requirements can be met.

[0111] Step 104: Combine any one of the first refrigerant circuits that can be adjusted to the desired opening degree as a first execution circuit, and combine any one of the second refrigerant circuits that can be adjusted to the desired opening degree as a second execution circuit.

[0112] After determining in step 103 whether the valves in the first refrigerant circuit combination and the second refrigerant circuit combination can reach the desired opening degree, it is determined whether all the valves in the first refrigerant circuit combination and the second refrigerant circuit combination can be adjusted to the desired opening degree. If all of them can be adjusted to the desired opening degree, then any one of the first refrigerant circuit combinations is used as the first execution circuit to execute the control command, and any one of the second refrigerant circuit combinations is used as the second execution circuit to execute the control command.

[0113] Step 105: Perform corresponding switching control according to the desired opening degree of each group of valves in the first and / or second execution loops.

[0114] After determining the execution circuit according to the battery / cabin thermal management request, the corresponding valve body and compressor state are switched according to the desired opening degree of each valve body in the first and / or second execution circuit. The vehicle system completes the state switching of each valve body and compressor according to a predetermined switching procedure, which includes pre-set valve body and compressor switching control commands. It should be noted that the embodiments disclosed in this disclosure do not limit the valve body and compressor switching procedure.

[0115] This disclosure provides a refrigerant circuit mode control method, which acquires a pre-set basic circuit in the vehicle's infotainment system, acquires at least two preset refrigerant circuits that can meet thermal management requests, determines the desired opening degree of the valve body in each refrigerant circuit, and each refrigerant circuit includes at least one valve body; the thermal management requests include battery thermal management requests and / or cabin thermal management requests; in response to the battery / cabin thermal management requests, a first refrigerant circuit combination that meets the battery thermal management request is determined, and a second refrigerant circuit combination that meets the cabin thermal management request is determined; it is determined whether the actual opening degree of the valve body in the first and second refrigerant circuit combinations can be adjusted to the desired opening degree; any first refrigerant circuit combination that can be adjusted to the desired opening degree is used as a first execution circuit, and any second refrigerant circuit combination that can be adjusted to the desired opening degree is used as a second execution circuit; and corresponding switching control is performed according to the desired opening degree of each valve body in the first and / or second execution circuits. Compared with related technologies, the embodiments of this disclosure determine the corresponding refrigerant circuit combination based on the battery thermal management request and / or the cabin thermal management request, and reconfigure the corresponding execution circuit by comparing the actual opening degree of the valve body with the expected opening degree. This simplifies the control process of the vehicle thermal management system and realizes a general control process for switching vehicle thermal management modes.

[0116] As one possible implementation of this disclosure, before executing the corresponding switching control in step 105, the following method can be used, such as... Figure 2 As shown, Figure 2 A flowchart illustrating another refrigerant circuit mode control method provided in this disclosure embodiment includes:

[0117] Step 201: Combine the refrigerant circuits common to the first and second execution circuits to form a third refrigerant circuit combination.

[0118] The vehicle's infotainment system shares the same thermal management system with the battery. Therefore, when both the passenger compartment and the battery have simultaneous needs, the refrigerant circuit is selected based on the principle of meeting the needs of both the passenger compartment and the battery. For example, taking an array, one row from the first refrigerant circuit and one row from the second refrigerant circuit combination are combined to form a 1*4 array, which is the third refrigerant circuit. For instance, when the first refrigerant circuit combination array is:

[0119] {1,101

[0120] 1,2

[0121] 101,101}

[0122] The combination data for the second refrigerant circuit is as follows:

[0123] {1,101

[0124] 101,101

[0125] 101,101}

[0126] Since the first refrigerant circuit combination and the second refrigerant circuit combination share a common circuit 1, the third refrigerant circuit combination is determined to be {1, 101, 101, 101}.

[0127] Step 202: Combine the third refrigerant circuit as the third execution circuit of the refrigerant cycle.

[0128] The identified third refrigerant circuit combination is used as an execution circuit for vehicle thermal management.

[0129] As one possible implementation of this disclosure, the switching control based on the expected opening degree of each group of valves in the first and / or second execution loops can also be implemented in, but is not limited to, the following ways: for example, the switching control based on the expected opening degree of each group of valves in the third execution loop.

[0130] As a refinement of the above embodiments, the step of performing corresponding switching control based on the desired opening degree of each group of valve bodies in the third execution loop can also be implemented in, but is not limited to, the following ways: Figure 3 As shown, Figure 3 A flowchart illustrating another refrigerant circuit mode control method provided in this disclosure embodiment includes:

[0131] Step 301: Determine the desired opening degree corresponding to each valve body in the third execution circuit.

[0132] As a refinement of the embodiments of this disclosure, the determination of the expected opening degree corresponding to each valve body in the third execution loop can also be implemented in, but is not limited to, the following ways: based on each refrigerant loop in the third refrigerant loop combination, query the expected opening degree of a group of valve bodies corresponding to each refrigerant loop according to a preset correspondence; wherein, the preset correspondence is the correspondence between the refrigerant loop and each valve body in the refrigerant loop, and the expected opening degree corresponding to each valve body; the expected opening degrees of a group of valve bodies corresponding to the queried refrigerant loop are merged to obtain the expected opening degree of the valve body in the third execution loop.

[0133] Step 302: Perform corresponding switching control according to the desired opening degree of each valve body.

[0134] Based on the desired valve opening of the third execution circuit, each valve body switches states according to the desired opening.

[0135] As a refinement of the above embodiments, the step of performing corresponding switching control according to the desired opening degree of each valve body can be implemented in the following ways, but is not limited to: obtaining a switching configuration file; the switching configuration file is used to record the switching sequence between the compressor and the valve body; according to the switching sequence between the compressor and the valve body recorded in the switching configuration file, the compressor is switched to the corresponding desired speed and the preset valve body is switched to the corresponding desired opening degree.

[0136] As one possible implementation of this disclosure, before determining a first refrigerant circuit combination that satisfies the battery thermal management request and a second refrigerant circuit combination that satisfies the cockpit thermal management request, the following method may be used, including:

[0137] Configure a first correspondence between the source of configuration requirements and different thermal management requests, wherein the source of configuration requirements includes the battery or the cockpit, and the thermal management requests include battery thermal management requests and cockpit thermal management requests;

[0138] Configure a second correspondence between the thermal management request and the refrigerant circuit combination.

[0139] The first correspondence is the pre-set mapping relationship between sensor signals and thermal management mode requests. The sources of the requests mentioned here include sensor signals and signals generated by human temperature control. The second correspondence is the mapping relationship between thermal management mode requests and refrigerant circuit combinations. In this embodiment, the vehicle temperature adjustment is divided into two parts: the passenger compartment and the battery. Therefore, adjustment modes in the passenger compartment thermal management mode and the battery thermal management mode are preset respectively. However, this design of the present disclosure embodiment does not limit the number of thermal management modes.

[0140] As a refinement of the above embodiments, after configuring the correspondence between thermal management requests and refrigerant circuit combinations, the determination of the first refrigerant circuit combination that satisfies the battery thermal management request and the determination of the second refrigerant circuit combination that satisfies the cockpit thermal management request can also be implemented in, but is not limited to, the following ways: Figure 4 As shown, Figure 4 A flowchart illustrating another refrigerant circuit mode control method provided in this disclosure embodiment includes:

[0141] Step 401: Query the battery thermal management request corresponding to the battery based on the first correspondence relationship.

[0142] Step 402: Based on the second correspondence, query the first refrigerant circuit combination corresponding to the battery thermal management request.

[0143] Step 403: Based on the first correspondence, query the cockpit thermal management request corresponding to the cockpit.

[0144] Step 404: Based on the second correspondence, query the second refrigerant circuit combination corresponding to the cabin thermal management request.

[0145] In this embodiment, vehicle temperature regulation is divided into two parts: the passenger compartment and the battery. Therefore, regulation modes are preset for both the passenger compartment thermal management mode and the battery thermal management mode. The steps for both are basically the same, the difference being that a mapping relationship is established between the demand source and different thermal management mode requests, and a mapping relationship is established between the thermal management mode requests and the refrigerant circuit combination. The refrigerant circuit combination is ultimately determined through these different mapping relationships.

[0146] As one possible implementation of this disclosure, the determination of whether the actual opening degree of the valve body in the first refrigerant circuit combination and the second refrigerant circuit combination can be adjusted to the desired opening degree can also be implemented in, but is not limited to, the following ways: Figure 5 As shown, Figure 5 A flowchart illustrating another refrigerant circuit mode control method provided in this disclosure embodiment includes:

[0147] Step 501: Determine whether the actual opening degree of each valve body in the first refrigerant circuit combination and the second refrigerant circuit combination is the same as the expected opening degree.

[0148] For example, when the expected opening of the electronic expansion valve is open and the actual opening is closed, it is determined that the actual opening is different from the expected opening, and step 503 is executed; when the expected opening of the electronic expansion valve is closed and the actual opening is closed, it is determined that the opening is the same as the expected opening, and step 502 is executed, without needing to determine whether the valve body is in an adjustable state.

[0149] Step 502: If they are the same, then determine that each valve body can be adjusted to the desired opening degree.

[0150] Step 503: If they are different, determine whether there is a faulty valve body in each valve body.

[0151] If the actual opening degree is different from the expected opening degree, determine whether the valve body is in an adjustable state, that is, determine whether the valve body has malfunctioned, and determine whether the valve body can be adjusted to the expected opening degree. If the valve body is in an adjustable state, proceed to step 204; if it is in an unadjustable state, proceed to step 505.
