Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle cabin thermal management, in particular to a vehicle cabin thermal management system, a vehicle cabin thermal management method, a vehicle cabin thermal management device, an electronic device, a storage medium and a vehicle. BACKGROUND

[0002] For a manned vehicle, the vehicle cabin can be used as a place for night rest. In the face of low temperature environment, the vehicle cabin needs to be heated to ensure a high enough comfortable temperature and a long enough time to maintain the comfortable temperature.

[0003] Therefore, the heating rate and temperature maintenance time in the vehicle cabin are important evaluation indexes.

[0004] For example, when the vehicle is camping, the vehicle is in an off state, the engine does not work, and the vehicle generator also does not work. However, it is not guaranteed that the vehicle is parked in a place where external power supply can be connected every night. Therefore, the vehicle battery power can only be discharged and cannot be effectively supplemented. Under this condition, the power supply of the camping wind heating system in the vehicle cabin can only rely on the battery power itself.

[0005] 1. The scheme in the application "A wind warm PTC vehicle temperature heating control method and device" (CN202311814543.2) has a complex structure;

[0006] 2. The scheme in the application "Electric heating container tank" (CN202311246370.9) does not use the vehicle battery as the power supply system, so it cannot guarantee that the camping heater can work under any conditions at any place;

[0007] 3. In the existing scheme, it is not clear whether the engine / motor (new energy) needs to work. If the engine / motor (new energy) works, although the power supply of the heater can be guaranteed, the noise and vibration generated by the vehicle cannot guarantee the rest quality of the people in the container;

[0008] 4. In the existing scheme, the capacity of the battery is not clear. That is, under the condition of relying only on the battery power supply, whether the heater can meet the minimum 8h working time (the required sleep time at night).

[0009] Therefore, a vehicle cabin thermal management scheme is needed to balance energy storage, working period, heating efficiency, etc., so that the vehicle cabin can provide a relatively comfortable environment. SUMMARY

[0102] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0103] Figure 1 is a structural diagram of a vehicle cabin thermal management system provided by one or more embodiments of the present application.

[0104] As shown in Figure 1 the vehicle cabin thermal management system comprises:

[0105] a cabin module, a battery module, an oil tank module, an internal combustion engine module, a heating module and a temperature control module;

[0106] the cabin module is used for encapsulating a temperature control area;

[0107] the battery module is used for storing electric energy;

[0108] the oil tank module is used for storing oil;

[0109] the internal combustion engine module is used for consuming oil to generate electricity;

[0110] the heating module is used for heating the temperature control area;

[0111] a temperature control module for monitoring the temperature of the temperature control area;

[0112] the oil passage of the oil tank module is connected to the internal combustion engine module;

[0113] the internal combustion engine module comprises a generator;

[0114] the power loop of the generator and the heat circulation loop of the internal combustion engine are connected to the temperature control module;

[0115] the temperature control module controls the power loop of the generator to be connected to the battery module or / and the heating module;

[0116] the temperature control module controls the heat circulation loop of the internal combustion engine to be connected to the heating module;

[0117] the heating end of the heating module is located in the temperature control area of the compartment module;

[0118] the temperature control module comprises a temperature detection end and a timing detection end;

[0119] the temperature detection end is located in the temperature control area and outside the temperature control area;

[0120] the timing detection end triggers the timing according to the signal state of the temperature detection end.

[0121] Specifically, in one embodiment, the upper equipment of the vehicle chassis is a closed compartment, which has a lying position for rest in addition to medical facilities. With the help of the engine and battery of the vehicle chassis, the heating device is driven to heat the compartment to resist the low temperature environment. Especially at night, it is necessary to maintain a relatively stable comfortable temperature for a long time to help the passengers on the lying position to smoothly pass the night.

[0122] The heating module can be an electric heating device or a device utilizing the heat dissipation circulation of the engine. The electric heating device is usually driven by the battery or by the generator driven by the engine. The generator can charge the battery while driving the electric heating device, or the engine can charge the battery while utilizing the heat dissipation circulation of the engine to transfer heat to the compartment.

[0123] During the night heating, the temperature in the compartment (temperature control area) can be quickly raised by the engine first, and then the temperature can be maintained by the heat preservation function of the compartment. During the temperature maintenance period, the electric heating device is driven by the battery to work at a relatively low power, so that the temperature is maintained in a relatively comfortable state, avoiding the interference of engine vibration on the rest of the people in the compartment.

[0124] The temperature in the compartment is monitored by the temperature detection end (such as a temperature sensor), and the working time of the engine for quickly heating the compartment is controlled by the timing detection end to prevent the temperature from being too high or the time from being too long to affect the rest of the people in the compartment.

[0125] The heat storage device, such as a water tank or a water bag, is arranged in the temperature control area in the vehicle cabin and connected to the heat dissipation pipeline of the engine to quickly and as much as possible absorb heat and enhance the duration of maintaining the temperature in the vehicle cabin. The electric heating device can heat the water tank or the water bag in addition to heating the air in the vehicle cabin to maintain the duration of the comfortable temperature in the vehicle cabin.

[0126] In the embodiment, the heating end of the heating module includes an electric heating end and a heat cycle heating end.

[0127] The temperature control module controls the electric power circuit of the generator and the heat cycle circuit of the internal combustion engine, and the electric heating end and the heat cycle heating end of the electric heating module heat the temperature control area of the cabin module.

[0128] According to the electric heating end and the heat cycle heating end of the electric heating module heating the temperature control area of the cabin module, the temperature control module controls the starting motor of the internal combustion engine module driven by the battery module.

[0129] The battery module is connected to the starting motor of the internal combustion engine module through the temperature control module circuit.

[0130] Specifically, the electric heating end is driven through the electric power circuit and connected to the output end of the battery electrode or the motor under the control of the temperature control module.

[0131] The temperature control module controls not only the electric power circuit but also the heat cycle circuit, and the heat cycle heating end is connected to the heat dissipation pipeline of the engine to directly introduce the waste heat generated by the engine combustion into the vehicle cabin.

[0132] Since the starting of the engine depends on the battery, the discharge of the battery has a lower limit, which is set to at least enable the engine to start again. When it is found that the battery power is close to the lower limit, the engine is started by the battery to drive the generator to generate electricity to charge the battery, and at the same time, the waste heat of the generator is used to supplement the heat in the vehicle cabin to improve the temperature in the vehicle cabin. For example, when the temperature control module detects that the battery voltage is low, the battery is connected to the starting motor of the engine to start the engine.

[0133] In addition to the switches and valves for controlling the electric power circuit and the heat cycle circuit, the temperature control module also includes terminals for connecting the electric power circuit and the heat cycle circuit, which can be temporarily disconnected when the vehicle power module (such as the vehicle head) is used alone and the vehicle cabin is left in place. For example, the vehicle head is driven by the engine, and after driving away, the battery is used to maintain the temperature in the temperature control area in the vehicle cabin.

[0134] Figure 2 The flowchart of the vehicle cabin thermal management method provided by one or more embodiments of the present application is shown in FIG. 1.

[0135] The vehicle cabin thermal management method includes the following steps: Figure 2

[0136] ​Step S1, obtain temperature control interval information and temperature control time information;

[0137] Step S2, generate temperature detection parameters of the temperature control module according to the temperature control interval information;

[0138] Step S3, generate timing detection parameters of the temperature control module according to the temperature control time information;

[0139] Step S4, generate internal combustion engine start-stop control information and battery charge-discharge control information according to the temperature control interval information and the temperature control time information.

[0140] Specifically, the temperature control module is equivalent to an embedded system or part of the function of the car machine system. It has an editable and storable function. In the temperature control module, parameter data can be input in advance.

[0141] The temperature control interval information includes the temperature interval that the vehicle cabin needs to control. The temperature control time information includes the time length of controlling the engine to start working and the time length of the battery working to reach the temperature interval that the vehicle cabin needs to control.

[0142] In this embodiment, it also includes:

[0143] Obtain the temperature difference information inside and outside the temperature control area;

[0144] Generate heat loss information of the temperature control area according to the temperature difference information;

[0145] Generate the reserve heat value information inside the temperature control area according to the heat loss information, the temperature control interval information and the temperature control time information.

[0146] Specifically, in different low-temperature environments, the heating demand of the vehicle cabin is different. The heating efficiency of the heating module, the oil carried, the battery energy storage, etc. are all limited, and the reserve heat value required for heating the temperature control area needs to be predicted according to the temperature difference information inside and outside the temperature control area. The reserve heat value can be used to calculate the required oil, the heating power and efficiency of the electric heating module.

[0147] In this embodiment, it also includes:

[0148] Obtain the efficiency information of the internal combustion engine converting the reserve heat value inside the temperature control area;

[0149] Generate oil reserve threshold information according to the reserve heat value information inside the temperature control area and the efficiency information of the internal combustion engine converting the reserve heat value inside the temperature control area;

[0150] Set the oil reserve according to the oil reserve threshold information.

[0151] Specifically, when the engine is the main heating end energy source, it is necessary to focus on whether the oil reserve is sufficient. The engine has a certain efficiency in the conversion process, and the oil reserve needs to consider the heat loss of the vehicle compartment, the heat loss of the engine, and the loss during the conversion of electric energy.

[0152] In this embodiment, it also includes:

[0153] Obtain the efficiency information of the battery conversion temperature control area reserve heat value;

[0154] According to the temperature control area reserve heat value information and the efficiency information of the battery conversion temperature control area reserve heat value, generate battery power reserve threshold information;

[0155] According to the battery power reserve threshold information, set the power reserve.

[0156] Specifically, when the battery is the main heating end energy source (such as the main way to maintain the temperature of the vehicle compartment), it is necessary to focus on whether the electric energy reserve is sufficient.

[0157] In this embodiment, it also includes:

[0158] Obtain the information of the battery capacity and the fuel tank capacity;

[0159] According to the temperature control area reserve heat value information, set the energy reserve strategy;

[0160] The energy reserve strategy includes setting the lower limit of the battery power reserve of the battery engine internal combustion engine;

[0161] According to the lower limit of the battery power reserve of the battery engine internal combustion engine, set the battery capacity and the priority of the battery charging.

[0162] Specifically, since the battery and the fuel tank both have the ability to store energy, from the application point of view, each has its own advantages. According to the preset application scenario, the proportion and emphasis of using the battery and the engine are allocated. Generally, the convenience of battery energy storage is poor, and the release of electric energy is relatively convenient. For example, according to the beginning stage of rest, the engine is used preferentially, and the engine working time is short, which has little effect on rest, and most of the time is the battery working and maintaining. When relying more on the battery, the priority of the battery capacity is higher than that of the priority of the oil tank capacity. When it is more convenient to obtain fuel in the environment, the priority of the oil tank capacity is higher. But the start of the engine must rely on the battery, so in the design, at least a safe lower limit of the battery power reserve is reserved for the battery. The part of the safe lower limit of the battery power reserve has a higher priority than other parts of the stored electric energy of the battery, that is, whether a separate battery or an integrated battery is used, a power reserve for starting the engine is reserved for starting the engine.

[0163] In the embodiment, further comprising:

[0164] Obtaining information of a pre-travel mileage of the vehicle under the temperature control task;

[0165] Generating information of non-temperature control fuel consumption according to the information of the pre-travel mileage of the vehicle under the temperature control task;

[0166] Obtaining information of a current battery capacity and an oil reserve;

[0167] Obtaining information of an adjusted distribution of the battery capacity and the oil reserve according to the information of the non-temperature control fuel consumption, the information of the temperature control interval, and the information of the temperature control time;

[0168] The information of the adjusted distribution of the battery capacity and the oil reserve comprises a consumption purpose, a consumption proportion, and a consumption process of the current battery capacity and the oil reserve based on a preset priority of the pre-travel mileage, the temperature control interval, or the temperature control time.

[0169] Specifically, since the vehicle needs to continue to travel tomorrow after parking, the oil reserve and the battery capacity reserve cannot be excessively consumed in the case of having a travel task tomorrow. If necessary, the comfort of the vehicle cabin temperature needs to be reduced to obtain the battery capacity for normal starting of the vehicle tomorrow and to ensure that the oil can reach the preset destination.

[0170] In the embodiment, further comprising:

[0171] Obtaining personnel physiological characteristic information;

[0172] Setting threshold information of the temperature control interval or the temperature control time according to the personnel physiological characteristic information;

[0173] Adjusting a consumption proportion and a consumption process of the current battery capacity and the oil reserve in the consumption purpose of heating in the temperature control interval according to the threshold information of the temperature control interval or the temperature control time;

[0174] Generating information of a mileage of the battery capacity and the oil reserve in the consumption purpose of vehicle travel according to the adjusted consumption proportion and the consumption process of the current battery capacity and the oil reserve in the consumption purpose of heating in the temperature control interval;

[0175] Specifically, the threshold of the temperature control interval or the temperature control time is limited by the personnel physiological characteristic. For example, if the overnight person in the vehicle cabin is an injured person, a more stable and comfortable temperature is needed, and if the overnight person in the vehicle cabin is a general traveler, the threshold interval of the adaptive temperature is relatively wide.

[0176] A reasonable temperature control interval or threshold value of temperature control time is set according to the physiological characteristics of the corresponding personnel. The consumption proportion and consumption process of the current battery power and oil reserves on the heating consumption in the temperature control area are adjusted in accordance with the reasonable temperature control interval or threshold value of temperature control time. For example, for the wounded passengers, more active resistance to the low temperature environment is needed, and the engine can be started multiple times to quickly raise the temperature in the vehicle cabin. The difficulty of insufficient battery energy storage to more actively maintain the temperature in the vehicle cabin is reduced.

[0177] In the embodiment, the threshold value information of the temperature control interval or the temperature control time is set according to the physiological characteristic information of the personnel, and includes:

[0178] The temperature control interval includes a first temperature threshold value and a second temperature threshold value;

[0179] The temperature control time includes a first time for heating the temperature control area to a temperature not lower than the first temperature threshold value under full power of the heating end;

[0180] The temperature control time further includes a second time for maintaining the temperature in the temperature control area to be not lower than the second temperature threshold value for a preset time parameter;

[0181] The heating efficiency information of the temperature control area under full power of the heating end is obtained;

[0182] The information of the current temperature in the temperature control area is obtained;

[0183] The parameter data of the first time is input into the temperature control module according to the heating efficiency information, the current temperature information in the temperature control area, and the first temperature threshold value information;

[0184] The working power of the heating end in the second time is set according to the heat loss information of the temperature control area, the current temperature information in the temperature control area, the second temperature threshold value information, and the second time information.

[0185] Specifically, according to the physiological characteristic information of a certain type of personnel, the first temperature threshold value is 21 degrees Celsius, and the second temperature threshold value is 18 degrees Celsius. Under full power of the heating end, the temperature control area is heated mainly in the form of engine heat cycle and supplemented by battery heating, so that the temperature in the vehicle cabin is quickly raised to 21 degrees Celsius.

[0186] When the temperature in the vehicle cabin rises to 21 degrees Celsius, the subsequent heat loss is mainly determined by the heat loss resistance performance of the vehicle cabin itself. Since heat loss is inevitable, and continuous engine work greatly interferes with the rest environment, the battery can be used to maintain the current temperature, which is not lower than 18 degrees Celsius.

[0187] Figure 3 is a structural diagram of a vehicle cabin thermal management device provided by one or more embodiments of the present application.

[0192] The control information module is configured to generate internal combustion engine start-stop control information and battery charge-discharge control information according to the temperature control interval information and the temperature control time information.

[0193] It is worth noting that, although the system only discloses the information acquisition module, the temperature detection module, the timing detection module, and the control information module, it does not mean that the device is limited to the above basic functional modules. On the contrary, the meaning expressed by the present application is that, on the basis of the above basic functional modules, a person skilled in the art can add one or more functional modules to form an infinite number of embodiments or technical solutions in combination with the prior art. That is to say, the system is open rather than closed, and the protection scope of the present application claimed in the present embodiment cannot be limited to the above disclosed basic functional modules.

[0194] Through the above scheme, the following beneficial technical effects are obtained:

[0195] The present application avoids the time period of personnel rest by setting the start and stop of the engine, increases the charging time of the battery, reduces the discharging time of the battery, and increases the redundancy of maintaining the temperature of the carriage.

[0196] The present application evaluates the ability to maintain the temperature of the carriage by pre-judging the heat value of the energy storage, so as to early discover the insufficient energy storage and prevent excessive consumption of the energy storage, causing the inability to take the next action the next day and increasing the risk resistance in the wild.

[0197] The present application sets the priority of the vehicle function to use the limited energy reserve in important tasks as much as possible, and early discovers the boundary of the rest place attribute of the carriage.

[0202] Figure 7 Schematic diagram of the vehicle cabin temperature control state of one embodiment of the present application in an extreme environment of minus forty degrees.

[0203] In one embodiment, as shown in Figure 4 , the vehicle cabin heating system structure includes: 1 fuel tank; 2 heater; 3 heater controller; 4 heater control panel; 5 camping battery; 6 vehicle cabin.

[0204] The fuel tank functions to provide diesel to the heater; the heater is controlled by its controller, and after receiving diesel, it burns diesel according to a predetermined program and discharges heat energy through the fan, assuming that a 10 kW rated power and 100 m3 / h ventilation volume heater is selected for ease of calculation and illustration; the whole air heating heater (return air temperature sensor) is placed in the vehicle cabin, the exhaust port is connected to the outside of the vehicle, and the air outlet is connected to the air duct in the vehicle cabin, so as to realize the circulation of warm air in the vehicle cabin, accelerate the temperature rise in the vehicle cabin, and facilitate more accurate measurement of the temperature in the vehicle cabin by the return air temperature sensor; the heater controller is used to automatically adjust the working time and efficiency of the heater according to a predetermined strategy; the heater control panel can manually adjust the heating power and air volume; the vehicle cabin is a place for vehicle personnel to camp at night and is also the working environment of the heater.

[0205] In another embodiment, as shown in Figure 5 , the vehicle cabin heating system process, when the vehicle is in a normal winter use environment, the rated power of the heater is 10 kW, the ventilation volume is 100 m3 / h, and the working current is about 15 A when heating, and its own control logic is that when the heater return air temperature quickly reaches T℃, the return air temperature sensor sends information to the controller at this time, and the controller automatically reduces the heating power and fan air volume to continue working at a power of 10 kW x 40% and a ventilation volume of 100 m3 / h x 40%, so as to protect the equipment from being damaged under the premise of ensuring that the temperature meets the standard.

[0206] When the vehicle is in extremely cold environment (ambient temperature below minus 30 DEG C), the temperature of the heater itself back air temperature sensor will reach T DEG C at a very slow speed, at this time, in order to meet the temperature in the vehicle cabin in extremely cold environment rises rapidly and reaches above 18 DEG C within a certain time, and maintains at least 8h to meet the comfort, if according to one of the heater itself strategy, the vehicle itself in the full state of the battery capacity must be greater than or equal to 15A x 8h = 120Ah when there is no other camping power equipment, and due to the existence of the heater, the vehicle generally needs to be matched with the oil pump and the ventilation system, the 8h power consumption nearly doubles, and if additional power equipment is used during camping, the battery is in a state of power shortage on the second day, and the vehicle cannot be started. Therefore, considering the vehicle power state and the volume and volume of the battery, the new strategy is added in the paper, when the heater back air temperature sensor does not reach the set temperature, but the working time reaches t min, the heater power is reduced to 10kW x 80%, and the ventilation volume is reduced to 100 x 80m3 / h, until the back air temperature sensor reaches T DEG C, and the average heating current can be reduced to 10A in the strategy mode. The simulation result curves of-30 DEG C and-40 DEG C are shown in Figs. 1 and 2. Figure 6 、 7

[0207] The heater has a rated power of 10kW and a ventilation volume of 100m3 / h, and its own control logic is that when the heater back air temperature reaches T DEG C, the back air temperature sensor sends information to the controller, and the controller automatically reduces the heating power and the fan volume.

[0208] In addition, the control strategy is provided, that is, when the heating time reaches t, the heater controller controls the heater to no longer work at rated power, and the power is reduced to 10kW x 80%, and the ventilation volume is reduced to 100 x 80m3 / h, and the heater itself control logic is matched. When the power is reduced, the upper limit value of the rotary knob switch is adjusted in proportion to reduce, so that the temperature in the vehicle cabin meets the index and a large amount of battery power is saved, and the vehicle cannot be started on the next day. At the same time, when the power is reduced, the oil pump volume is also reduced, and the average oil consumption within 8h can be reduced from 1.25L / h to 0.9L / h, that is, the total daily oil consumption can be reduced by 2.8L, further saving energy, improving fuel utilization, and achieving more and more saving.
