Description

Technical Field

[0001] The present application relates to the field of vehicle cabin thermal management, and 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 Art

[0002] For passenger vehicles, the cabin can be used as a place to rest at night. In low temperature environments, the cabin needs to be heated to ensure a high enough comfortable temperature and to maintain the comfortable temperature for a long enough time.

[0003] Therefore, the heating rate and temperature holding time in the car are important evaluation indicators.

[0004] For example, when the vehicle is camping, the vehicle is turned off, the engine is not working, and the vehicle generator is also not working; and it is impossible to ensure that the vehicle is parked in a place where an external power source can be connected every night; the vehicle battery only outputs power but does not input power, and it cannot be guaranteed to be effectively replenished. Under this condition, the power supply of the camping air heating system in the car can only rely on the power of the battery itself.

[0005] 1. The structure of the scheme of "A method and device for controlling the temperature in a wind-heated PTC vehicle" (CN202311814543.2) is relatively complex;

[0006] 2. The power supply system in the scheme of "Electrically Heated Container Tank" (CN202311246370.9) is not an on-board battery, so it cannot be guaranteed that the camping heater can work in any location and under any working conditions;

[0007] 3. In the existing solution, the vehicle heater does not specify whether the engine / motor (new energy) needs to work. If the engine / motor (new energy) is working, 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 cargo box;

[0008] 4. The existing solution does not specify the battery capacity, that is, whether the heater can meet the minimum working time of 8 hours (sufficient sleep time is required at night) when powered only by the battery.

[0009] Therefore, a solution for cabin thermal management is needed to provide a relatively comfortable environment in the cabin by balancing energy reserves, working hours, heating efficiency, etc. Summary of the invention

[0102] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0104] like Figure 1 The cabin thermal management system shown includes:

[0105] Carriage module, battery module, fuel tank module, internal combustion engine module, heating module and temperature control module;

[0106] The compartment module is used to encapsulate the temperature control area;

[0107] A battery module for storing electrical energy;

[0108] A fuel tank module, used for storing fuel;

[0109] An internal combustion engine module, used to consume oil to generate electricity;

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

[0111] Temperature control module, used to monitor the temperature of the temperature control area;

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

[0113] The internal combustion engine module includes a generator;

[0114] The power circuit of the generator and the heat cycle circuit of the internal combustion engine are connected to the temperature control module;

[0115] The temperature control module controls the power circuit of the generator to connect the battery module and / or the heating module;

[0116] The temperature control module controls the heat circulation loop of the internal combustion engine to connect 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 includes a temperature detection terminal and a timing detection terminal;

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

[0120] The timing detection end triggers 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 and comfortable temperature for a long time so that the occupants in the lying position can spend the night smoothly.

[0122] The heating module can be an electric heating device or a device that uses the engine heat dissipation cycle. Usually, the electric heating device is driven by a battery or by the engine driving a generator. The generator can charge the battery while driving the electric heating device; or the engine can charge the battery while transferring heat to the vehicle compartment using the engine heat dissipation cycle.

[0123] When heating at night, the engine can first quickly raise the temperature in the cabin (temperature control area), and then use the insulation function of the cabin to maintain the temperature. During the temperature maintenance period, the battery drives the electric heating device to work at a lower power to keep the temperature at a relatively soothing state, avoiding the vibration of the engine from disturbing the rest of the people in the cabin.

[0124] The temperature in the car is monitored through a temperature detection terminal (such as a temperature sensor), and the working time of the engine to quickly heat the car is controlled through a timing detection terminal to prevent the temperature from being too high or the time from being too long and affecting the rest of the people in the car.

[0125] A heat storage device, such as a water tank or water bag, is installed in the cabin (temperature control area) and connected to the engine's heat dissipation pipeline to absorb heat as quickly and as much as possible to increase the duration of maintaining the cabin temperature. In addition to heating the cabin air, the electric heating device can also heat the water tank or water bag to maintain a comfortable cabin temperature for a long time.

[0126] In this embodiment, the heating end of the heating module includes: an electric heating end and a thermal cycle heating end;

[0127] The temperature control module controls the 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 compartment module;

[0128] The temperature control area of ​​the compartment module is heated according to the electric heating end and the heat cycle heating end of the electric heating module, and the temperature control module controls the battery module to drive the starter motor of the internal combustion engine module;

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

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

[0131] In addition to controlling the power circuit, the temperature control module also controls the heat cycle circuit. The heating end of the heat cycle is connected to the engine's heat dissipation pipeline, directly introducing the waste heat generated by the engine combustion into the vehicle compartment.

[0132] Since the engine starts relying on the battery, the battery discharge has a lower limit, which is set to at least be able to start the engine again. When the battery charge is close to the lower limit, the battery starts the engine to drive the generator to generate electricity to charge the battery, and the generator waste heat is used to supplement the heat in the car to increase the temperature in the car. For example, when the temperature control module detects that the battery voltage is low, the battery is connected to the engine's starter motor to start the engine.

[0133] In addition to switches and valves for controlling the power circuit and the heat cycle circuit, the temperature control module also includes terminals for connecting the power circuit and the heat cycle circuit. When the vehicle power module (such as the front of the vehicle) is used alone and the vehicle compartment is left in place, the terminals can be temporarily disconnected. For example, when the front of the vehicle is driven by the engine, after leaving, the vehicle compartment retains the battery to maintain the temperature in the temperature control area of ​​the vehicle compartment.

[0134] Figure 2 It is a flow chart of a vehicle compartment thermal management method provided by one or more embodiments of the present invention.

[0135] like Figure 2 The illustrated vehicle cabin thermal management method includes:

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

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

[0138] Step S3, generating a timing detection parameter of the temperature control module according to the temperature control time information;

[0139] Step S4, generating 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 a part of the vehicle system. It has editable and storable functions. In the temperature control module, parameter data can be pre-entered.

[0141] The temperature control range information includes the temperature range that the compartment needs to be controlled in. The temperature control time information includes the temperature range that the compartment needs to be controlled in, the duration of controlling the engine start-up work, the battery working time and other information.

[0142] In this embodiment, it also includes:

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

[0144] Generate heat loss information of the temperature control area based on the temperature difference information;

[0145] Based on the heat loss information, temperature control range information and temperature control time information, the reserve calorific value information in the temperature control area is generated.

[0146] Specifically, in different low-temperature environments, the cabin heating requirements are different. The heating efficiency of the heating module, the fuel carried, the battery energy storage, etc. are all limited. It is necessary to predict the reserve calorific value required for heating the temperature-controlled area based on the temperature difference information inside and outside the temperature-controlled area. The reserve calorific value can be used to calculate the required fuel, heating power, efficiency, etc. of the electric heating module.

[0147] In this embodiment, it also includes:

[0148] Obtaining efficiency information of the reserve calorific value in the conversion temperature control area of ​​the internal combustion engine;

[0149] Generate fuel reserve threshold information based on the reserve calorific value information in the temperature control area and the efficiency information of the internal combustion engine converting the reserve calorific value in the temperature control area;

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

[0151] Specifically, when the engine is used as the main source of energy for heating, it is important to consider whether the fuel reserve is sufficient. The engine has a certain efficiency during the conversion process, and the fuel reserve needs to consider the heat loss of the car, the heat loss of the engine, and the loss during the conversion of electrical energy during the conversion of the reserve heat value in the temperature control area.

[0152] In this embodiment, it also includes:

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

[0154] Generate battery power reserve threshold information based on the reserve calorific value information in the temperature control area and the efficiency information of the battery converting the reserve calorific value in the temperature control area;

[0155] Set the power reserve according to the battery power reserve threshold information.

[0156] Specifically, when the battery is used as the main energy source for the heating end (eg, the main way to maintain the temperature of the vehicle cabin), it is important to consider whether the energy reserve is sufficient.

[0157] In this embodiment, it also includes:

[0158] Get information about battery capacity and fuel tank capacity;

[0159] Set energy reserve strategy based on reserve calorific value information in the temperature control area;

[0160] The energy reserve strategy includes setting a lower limit on the amount of power reserve for the battery to start the internal combustion engine;

[0161] The battery capacity and battery charging priority are set according to the lower limit of the power reserve of the battery to start the internal combustion engine.

[0162] Specifically, since both batteries and fuel tanks have the ability to store energy, each has its own advantages from an application perspective. According to the preset application scenarios, the proportion and emphasis of batteries and engines are allocated. Generally, batteries are less convenient for storing energy, but more convenient for releasing electrical energy. For example, according to the beginning of rest, the engine is used first, and the short working time of the engine has little effect on rest, and most of the time it is maintained by the battery. When the battery is relied on for more work, the priority of increasing the battery capacity in the design is higher than the priority of increasing the fuel tank capacity. When it is more convenient to obtain fuel in the environment, the priority of increasing the fuel tank capacity is higher. However, the start of the engine must rely on the battery, so at least a safe lower limit of power reserve must be reserved for the battery in the design. The part of the safe lower limit of power reserve reserved by this battery has a higher priority than the other parts of the electrical energy stored in other batteries, that is, whether a split battery or an integrated battery is used, the power used for starting the engine must be reserved.

[0163] In this embodiment, it also includes:

[0164] Obtain information about the vehicle's estimated mileage under the temperature control task;

[0165] Generate non-temperature-controlled fuel consumption information based on the vehicle's estimated mileage information under the temperature-controlled task;

[0166] Get information about current battery power and fuel reserves;

[0167] According to the information of non-temperature-controlled fuel consumption, the information of temperature-controlled interval and the information of temperature-controlled time, the information of battery power and fuel reserve adjustment allocation is obtained;

[0168] The information on the adjustment and allocation of battery power and fuel reserves includes the consumption purpose, consumption proportion and consumption progress of the current battery power and fuel reserves based on the preset priority of the vehicle's expected mileage, temperature control range or temperature control time.

[0169] Specifically, since the vehicle needs to continue driving tomorrow after parking, the fuel reserve and battery power reserve should not be over-consumed if there is a driving task tomorrow. If necessary, the cabin temperature needs to be lowered to provide enough battery power for the vehicle to start normally tomorrow and ensure that the fuel can reach the preset destination.

[0170] In this embodiment, it also includes:

[0171] Obtaining information on the physiological characteristics of personnel;

[0172] According to the physiological characteristics of personnel, set the threshold information of temperature control interval or temperature control time;

[0173] According to the threshold information of the temperature control interval or the temperature control time, the consumption proportion and consumption progress of the current battery power and fuel reserve for heating consumption in the temperature control area are adjusted;

[0174] According to adjusting the consumption proportion and consumption progress of the current battery power and fuel reserve in the heating consumption purpose in the temperature control area, the information of the mileage of the battery power and fuel reserve in the vehicle driving consumption purpose is generated.

[0175] Specifically, the thresholds for setting the temperature control range or temperature control time are limited by the physiological characteristics of the people. For example, if the people staying overnight in the carriage are injured, a more stable and comfortable temperature is required. If the people staying overnight in the carriage are ordinary travelers, a wider threshold range for adapting to the temperature is required.

[0176] Under the corresponding physiological characteristics of the personnel, set a reasonable temperature control range or temperature control time threshold. Follow the reasonable temperature control range or temperature control time threshold, and adjust the current battery power and fuel reserve consumption ratio and consumption process for heating consumption in the temperature control area. For example, for injured passengers, it is necessary to fight against the low temperature environment more actively, and the quietness of rest can be sacrificed, and the engine can be started multiple times to quickly increase the temperature in the car. Reduce the dilemma of insufficient battery energy storage and inability to more actively maintain the temperature in the car.

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

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

[0179] The temperature control time includes the first time when the temperature in the temperature control area rises to not less than the first temperature threshold value when the heating end is working at full power;

[0180] The temperature control time also includes a second time of a preset time parameter for maintaining the temperature in the temperature control area not lower than a second temperature threshold;

[0181] Obtain the heating efficiency information in the temperature control area when the heating end is working at full power;

[0182] Get the temperature information in the current temperature control area;

[0183] According to the heating efficiency information, the temperature information in the current temperature control area and the first temperature threshold information, parameter data for the first time is set and input into the temperature control module;

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

[0185] Specifically, according to the physiological characteristics of a certain type of person, the first temperature threshold is 21 degrees Celsius and the second temperature threshold is 18 degrees Celsius. When the heating end is working at full power, it is equivalent to mainly using the engine heat cycle and supplemented by battery heating to quickly heat the temperature control area, so that the temperature in the car quickly rises to 21 degrees Celsius.

[0186] When the temperature in the car reaches 21 degrees Celsius, the subsequent heat loss depends on the car's resistance to heat loss. Since heat loss is inevitable and the continuous operation of the engine greatly interferes with the rest environment, the battery can be used to maintain the current temperature, not lower than 18 degrees Celsius.

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

[0188] like Figure 3 The compartment thermal management device shown includes: an information acquisition module, a temperature detection module, a timing detection module, and a control information module;

[0189] An information acquisition module is used to obtain temperature control interval information and temperature control time information;

[0190] A temperature detection module is used to generate temperature detection parameters of the temperature control module according to the temperature control interval information;

[0191] A timing detection module is used to generate timing detection parameters of the temperature control module according to the temperature control time information;

[0192] The control information module is used 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 present system only discloses an information acquisition module, a temperature detection module, a timing detection module, and a control information module, it does not mean that the present device is limited to the above-mentioned basic functional modules. Rather, what the present invention wants to express is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions. In other words, the present system is open rather than closed. Just because the present embodiment only discloses individual basic functional modules, it cannot be considered that the scope of protection of the claims of the present invention is limited to the above-mentioned basic functional modules.

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

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

[0196] This application pre-judges the calorific value of energy storage and evaluates the ability to maintain the temperature of the car compartment, so as to detect insufficient energy storage early and prevent excessive consumption of energy storage, which will cause the next step to be unable to take action the next day and increase the pressure of risk resistance in the field.

[0197] This application sets priorities for protecting vehicle functions, uses limited energy reserves as much as possible in important tasks, and discovers the boundaries of the resting place properties of the car as early as possible.

[0198] This application optimizes the temperature control process to ensure a comfortable temperature while minimizing the consumption of stored energy, so that people can get a comfortable rest in the car.

[0202] Figure 7 A schematic diagram of a cabin temperature control state in an extreme environment of minus forty degrees Celsius according to a specific embodiment of the present invention.

[0203] In a specific embodiment, Figure 4 As shown, the structure of the carriage heating system includes: 1. a fuel tank; 2. a heater; 3. a heater controller; 4. a heater control panel; 5. a camping battery; 6. a carriage.

[0204] The function of the fuel tank is to provide diesel to the heater; the heater is controlled by its controller, and after receiving the diesel, it burns the diesel according to the established program and discharges the heat energy through the fan. It is assumed that a heater with a rated power of 10kW and a ventilation volume of 100m3 / h is selected for the convenience of calculation and explanation; the overall air-heating heater (return air temperature sensor) is placed in the car, the exhaust port is connected to the outside of the car, and the air outlet is connected to the air duct in the car, so that the warm air can circulate in the car, accelerate the temperature rise in the car, and facilitate the return air temperature sensor to more accurately measure the temperature in the car; the heater controller is used to automatically adjust the working time and efficiency of the heater according to the established strategy; the heater control panel can manually adjust the heating power and air volume; the car is a place for the passengers to camp at night and also a working environment for the heater.

[0205] In another specific embodiment, Figure 5 The cabin heating system process shown in the figure is that when the vehicle is used in a normal winter environment, the rated power of the heater is 10kW, the ventilation volume is 100m3 / h, and the working current during heating is about 15A. Its own control logic is that when the return air outlet temperature of the heater will quickly reach T℃, the return air temperature sensor will send information to the controller, and the controller will then control the heating power and the fan air volume to automatically reduce, and continue to work at a power of 10kW×40% and a ventilation volume of 100m3 / h×40%, so as to protect its own equipment from damage while ensuring that the temperature meets the standard.

[0206] When the vehicle is in an extremely cold environment (ambient temperature is below -30℃), the temperature at the return air temperature sensor of the heater itself will reach T℃ at a very slow speed. At this time, in order to meet the requirement that the temperature in the cabin rises rapidly in an extremely cold environment and reaches above 18℃ within a certain period of time, and maintains for at least 8 hours to meet the comfort, if the heater itself strategy is followed, the vehicle itself, when there is no other camping electrical equipment, the battery capacity must be ≥15A×8h=120Ah when fully charged. Due to the existence of the heater, the vehicle generally needs to be equipped with an oil pump and ventilation system, and the 8-hour power consumption is almost doubled. If additional electrical equipment is used during the camping process, it is very easy to cause the battery to be in a low-power state on the second day, and the vehicle cannot be ignited. Therefore, the vehicle power consumption state and the capacity and volume of the battery are comprehensively considered. This article adds a new strategy. When the heater return air temperature sensor has not reached the set temperature, but the working time reaches t min, the heater power is reduced to 10kW×80%, and the ventilation volume is reduced to 100×80m3 / h until the return air temperature sensor temperature reaches T℃. In this strategy mode, the average heating current can be reduced to 10A; the simulation result curves at -30℃ and -40℃ are as follows Figure 6 , 7 shown.

[0207] When the heater is turned on for heating, the rated power is 10kW and the ventilation volume is 100m3 / h. Its own control logic is that when the return air outlet temperature of the heater reaches T℃, the return air temperature sensor sends information to the controller, and the controller then controls the heating power and the fan air volume to automatically reduce, and continue to work with a power (represented by Z) of 10kW×40% and a ventilation volume (represented by Y) of 100m3 / h×40%.

[0208] In addition, a 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, the power is reduced to 10kW×80%, the ventilation volume is reduced to 100×80m3 / h, and the heater's own control logic is coordinated. When the power decreases, the upper limit value that the knob switch can adjust decreases proportionally, thereby ensuring that the temperature in the car meets the index and saving a lot of battery power to prevent the vehicle from being unable to ignite the next day. At the same time, when the power is reduced, the pump oil volume is also reduced. The average fuel consumption within 8 hours can be reduced from the original 1.25L / h to 0.9L / h, that is, the total daily fuel consumption can be reduced by 2.8L, further saving energy, improving fuel utilization, and achieving more savings with more use.
