[0019] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.
[0020] A method and device for controlling a temperature regulating device according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.
[0021] Figure 1 A control method for a temperature regulating device provided in an embodiment of the present application is as follows: Figure 1 As shown, the method includes:
[0022] S101, obtaining the current working power corresponding to each temperature adjustment device;
[0023] S102, determining a target Hamiltonian for describing a temperature adjustment state according to a current working power corresponding to each temperature adjustment device;
[0024] S103, obtaining a target temperature requirement of the vehicle, and determining a target operating power of each temperature adjustment device according to the target temperature requirement and a target Hamiltonian;
[0025] S104. Control each temperature adjustment device according to the target operating power of each temperature adjustment device.
[0026] It can be understood that the control method of the temperature regulating device provided in this example is applied to vehicles, and the above-mentioned vehicles include vehicles with automatic driving or intelligent driving (including vehicles with manned functions (such as cars, buses, large buses, minibuses, etc.), vehicles with cargo functions (such as ordinary trucks, vans, trailers, closed trucks, tank trucks, flatbed trucks, container trucks, dump trucks, special structure trucks), special vehicles (such as logistics distribution vehicles, automatic guided transport vehicles AGV, patrol cars, cranes, cranes, excavators, bulldozers, forklifts, rollers, loaders, off-road engineering vehicles, armored engineering vehicles, sewage treatment vehicles, sanitation vehicles, vacuum trucks, floor washing vehicles, sprinkler trucks, sweeping robots, food delivery robots, shopping guide robots, lawn mowers, golf carts, etc.), vehicles with entertainment functions (such as entertainment vehicles, amusement park automatic driving devices, balance cars, etc.), rescue vehicles (such as fire trucks, ambulances, power repair vehicles, engineering rescue vehicles, etc.)), etc.
[0027] The vehicle is provided with a plurality of temperature regulating devices, for example, Figure 2 As shown, the vehicle is equipped with temperature regulating devices such as a compressor, a condenser, a fan, a liquid storage tank, an evaporator, a blower, and an expansion valve, and each temperature regulating device is used to cool and / or heat the vehicle. Among them, the compressor sucks in low-pressure and low-temperature refrigerant gas and compresses it into high-pressure and high-temperature gas to provide power for the cycle, and then transports the high-pressure and high-temperature gas to the condenser. After the high-pressure and high-temperature refrigerant enters the condenser, the condenser dissipates heat and transfers the heat released by the gaseous refrigerant to the outside world. After cooling with the aid of a fan or natural air flow, the refrigerant is converted into a high-pressure liquid. Then, the high-pressure liquid refrigerant flows into the liquid storage tank, which purifies the refrigerant, removes moisture and impurities, and acts as a buffer to provide a stable refrigerant flow for the subsequent process. Subsequently, the refrigerant flows from the liquid storage tank into the expansion valve, and the high-pressure liquid refrigerant is rapidly depressurized and cooled by the throttling effect of the expansion valve, becoming a low-pressure and low-temperature gas-liquid mixture. After the low-pressure and low-temperature refrigerant mixture enters the evaporator, it absorbs the heat of the air inside the car and completes the phase change from liquid to gas. At the same time, the blower in the evaporator blows the cooled air into the car to achieve a cooling effect. Finally, the evaporated low-pressure and low-temperature gaseous refrigerant is sucked into the compressor and enters the next cycle, thereby achieving continuous cooling operation of the vehicle; the same is true for heating, which will not be repeated here.
[0028] like Figure 2 As shown, based on the structure of the above-mentioned multiple temperature adjustment devices, the total cooling capacity of the vehicle = Q Pcool +Q bcool +Q ecool +Q ocool ; Among them, Q Pcool is the compressor cooling capacity, Q bcool is the cooling capacity of the blower, Q ecool is the evaporator cooling capacity, Qocool The cooling capacity generated for the remaining components (considering the heat generated by the components during operation, the cooling capacity can be ignored) and the total heating capacity on the vehicle are also determined by the various temperature control devices, which will not be elaborated here.
[0029] It can be understood that the cooling capacity and / or heating capacity of each temperature regulating device is related to the working power of the temperature regulating device. For example, taking the temperature regulating device as a blower, the cooling capacity of the blower is related to the air output of the blower, and the air output of the blower is affected by the working power of the blower, as follows:
[0030]
[0031] Among them, Q bcool is the cooling capacity of the blower, C p is the current specific heat capacity of air (C p The value of is affected by the environment and is a fluctuating value. p The value range is 900J / (kg·℃) to 1150J / (kg·℃)), ρ is the air density (ρ range is 1.1kg / m3 to 1.3kg / m3), ΔT is the difference between the previous moment and the current set target temperature. P is the total pressure, η is the blower full pressure efficiency (according to the relevant standards of the blower, the minimum value of the full pressure efficiency ranges from 0.6 to 0.9, where a small blower takes a small value and a large blower takes a large value), K is the motor capacity coefficient (K ranges from 1.05 to 1.1), P b is the working power of the blower.
[0032] For another example, taking the temperature regulating device as an evaporator, the cooling capacity of the evaporator is related to the working power of the evaporator, as follows:
[0033] Q ecool =m×c×(T in -T out );
[0034]
[0035] P e =m×(h2-h1)×A;
[0036] Among them, Q ecool is the cooling capacity of the evaporator, m is the mass flow rate of the refrigerant, c is the specific heat capacity of the refrigerant, Tin and Tout are the inlet and outlet temperatures of the refrigerant, h0 is the convective heat transfer coefficient of the external fluid (such as air), hi is the convective heat transfer coefficient of the internal fluid (such as refrigerant), Rw is the thermal resistance of the tube wall, Rs is the fouling thermal resistance, K eis the heat transfer coefficient, A is the heat transfer area, ΔTm is the log mean temperature difference (LMTD), which takes into account the effect of the fluid inlet and outlet temperatures on the heat transfer effect, P e is the working power of the evaporator.
[0037] Similarly, the working power of other temperature control devices will also affect the cooling capacity of the temperature control devices (such as the working power of the compressor will affect the cooling capacity of the compressor), which in turn affects the overall cooling capacity and / or heating capacity of the vehicle, which will not be elaborated here.
[0038] This application will use the working power of the temperature control device as the optimization variable to determine the target working power of each temperature control device; specifically, this application will first obtain the current working power corresponding to each temperature control device; taking the temperature control device including a compressor, an evaporator and a blower as an example, this application will obtain the current working power of the compressor, the current working power of the evaporator and the current working power of the blower.
[0039] Then, according to the current working power corresponding to each temperature regulating device, a target Hamiltonian for describing the temperature regulating state is determined, and the optimized control strategy is found through the target Hamiltonian.
[0040] The present application will also obtain the vehicle's target temperature requirement, where the target temperature requirement is the cooling or heating amount currently required by the vehicle. The cooling or heating amount currently required by the vehicle can be determined by the vehicle itself based on the ambient temperature inside the vehicle, and the cooling or heating amount currently required by the vehicle can be determined by relevant personnel based on actual needs.
[0041] This application determines the target operating power of each temperature control device according to the target temperature requirement and the target Hamiltonian, and subsequently controls each temperature control device to perform cooling according to the target operating power of each temperature control device, so that the overall cooling capacity or heating capacity of the vehicle can reach the target temperature requirement, thereby ensuring the cooling capacity of the vehicle.
[0042] According to the technical solution provided in the embodiment of the present application, the current working power corresponding to each temperature regulating device is obtained; according to the current working power corresponding to each temperature regulating device, the target Hamiltonian used to describe the temperature regulating state is determined; the target temperature requirement of the vehicle is obtained, and the target working power of each temperature regulating device is determined according to the target temperature requirement and the target Hamiltonian; according to the target working power of each temperature regulating device, each temperature regulating device is controlled. The present application determines the target working power of each temperature regulating device according to the determined target Hamiltonian and the target temperature requirement, thereby optimizing the working power of each temperature regulating device, saving system resources, and enabling the temperature change of the optimized temperature regulating device to reach the target temperature requirement, thereby ensuring that the target temperature requirement of the vehicle is met, and avoiding the problem in the related art that the power consumption problem is not taken into account when the temperature of the vehicle is adjusted, resulting in high power consumption and waste of system resources during the temperature adjustment process.
[0043] In some embodiments, Figure 3 As shown, according to the current working power corresponding to each temperature adjustment device, the target Hamiltonian for describing the temperature adjustment state is determined, including:
[0044] S301, constructing a target integral function according to the current working power corresponding to each temperature adjustment device;
[0045] S302, obtaining a temperature sensitivity coefficient, where the temperature sensitivity coefficient is used to characterize the sensitivity of temperature changes to total power consumption;
[0046] S303: construct a target Hamiltonian based on the target integral function and the temperature sensitivity coefficient.
[0047] It is understandable that when the vehicle is adjusting the temperature, the entire adjustment process is a dynamic continuous system, and the total power consumption of temperature adjustment changes with time. Through time integration, the dynamic characteristics of the dynamic continuous system of temperature adjustment can be captured, providing a basis for continuous time optimization.
[0048] The present application constructs a target integral function based on the current working power corresponding to each temperature control device. The target integral function is used to describe the total power consumption during the temperature control process. The optimization direction is clarified by establishing the target integral function, that is, under the premise of ensuring the cooling or heating effect, the optimal working power (target working power) corresponding to each temperature control device is determined, thereby realizing the optimized control of the operation of the temperature control device.
[0049] After obtaining the target integral function, in order to solve the target integral function to determine the target working power of each temperature regulating device, the present application will obtain the temperature sensitivity coefficient, which is used to characterize the sensitivity of temperature changes to total power consumption.
[0050] It can be understood that the working power variables, state variables and dynamic continuous system equations of temperature regulation of each temperature regulation device are effectively combined to solve complex dynamic optimization problems. This application transforms the optimization problem into a problem that satisfies a series of necessary conditions by constructing a Hamiltonian.
[0051] Specifically, the present application constructs a target Hamiltonian based on a target integral function and a temperature sensitivity coefficient, and then solves an optimal control solution for a temperature regulating device through the target Hamiltonian.
[0052] According to the technical solution provided in the embodiment of the present application, a target integral function is constructed according to the current working power corresponding to each temperature regulating device; a temperature sensitivity coefficient is obtained, and the temperature sensitivity coefficient is used to characterize the sensitivity of temperature changes to total power consumption; based on the target integral function and the temperature sensitivity coefficient, a target Hamiltonian is constructed, so that the target working power of each temperature regulating device is subsequently determined according to the determined target Hamiltonian and target temperature requirement, thereby optimizing the working power of each temperature regulating device, saving system resources, and enabling the cooling capacity of the optimized temperature regulating device to meet the target temperature requirement, ensuring that the target temperature requirement of the vehicle is met, and avoiding the problem in the related art that power consumption is not taken into account when the vehicle is temperature adjusted and controlled, resulting in high power consumption for temperature adjustment and waste of system resources.
[0053] In some embodiments, the temperature regulating device includes a compressor, an evaporator, and a blower; constructing a target integral function according to the current working power corresponding to each temperature regulating device includes:
[0054] Modeling is performed according to the current working power of the compressor, the evaporator and the blower at the first moment, and the target working power of the compressor, the evaporator and the blower at the second moment, to obtain a target integral function; the target integral function is used to describe the cumulative amount of total power consumption of the equipment during the period from the first moment to the second moment when the compressor, the evaporator and the blower are adjusted from their respective current working power to the target working power; specifically, modeling is performed according to the current working power of the compressor, the current working power of the evaporator and the current working power of the blower, to obtain a target integral function; the target integral function includes: Among them, P in (t) is the working power of the compressor at time t. When t is 0, P in (t) is the current working power of the compressor. When t is T, P in (t) is the target operating power of the compressor; P e (t) is the working power of the evaporator at time t. When t is 0, P e (t) is the current working power of the evaporator. When t is T, Pe (t) is the target operating power of the evaporator; P b (t) is the working power of the blower at time t. When t is 0, P b (t) is the current working power of the blower. When t is T, P b (t) is the target operating power of the blower.
[0055] The objective integral function is For example, the target Hamiltonian is H(P in , P e , P b ,λ)=P in +P e +P b +λ T ×f(P in , P e , P b ), where P in is the working power of the compressor, P e is the working power of the evaporator, P b is the working power of the blower; λ is the temperature sensitivity coefficient, λ T is the transpose of λ, f(P in , P e , P b ) is the rate of change of cooling capacity, and H is the Hamiltonian.
[0056] It can be understood that the above target integral function is only used for illustration, and relevant personnel can also establish a target integral function according to other temperature control devices. When the target integral function changes, the target Hamiltonian changes accordingly.
[0057] In some embodiments, Figure 4 As shown, the target operating power of each temperature regulating device is determined according to the target temperature requirement and the target Hamiltonian, including:
[0058] S401, determining a first constraint condition according to a target Hamiltonian, and generating a second constraint condition according to a corresponding relationship between each temperature adjustment device and a target temperature requirement;
[0059] S402: Calculate the target Hamiltonian according to the first constraint and the second constraint to obtain the target operating power of each temperature adjustment device.
[0060] It can be understood that the target Hamiltonian includes: H(P in , P e , P b ,λ)=P in +P e +P b +λ T×f(P in , P e , P b ) as an example, where P in is the working power of the compressor, P e is the working power of the evaporator, P b is the working power of the blower; λ is the temperature sensitivity coefficient, f(P in , P e , P b ) is the rate of change of cooling capacity; then the first constraint condition is determined according to the target Hamiltonian, and the first constraint condition includes:
[0061] H(x(T),P in (T), P e (T), P b (T), λ(T))=0, Among them, the above x represents the power state of the dynamic continuous system of temperature regulation at a certain moment, φ(x(T), T)φ(x(T), T) is the terminal cost function, and Q is the thermal load of the vehicle.
[0062] In some examples, the present application will also generate a second constraint condition based on the correspondence between each temperature regulating device and the target temperature requirement, and the second constraint condition is used to constrain the cooling capacity or heating capacity of each temperature regulating device in the dynamic continuous system of temperature regulation to not exceed the target temperature requirement of the dynamic continuous system of temperature regulation, thereby limiting the working power of each temperature regulating device. Specifically, taking the dynamic continuous system of temperature regulation including a compressor, an evaporator and a blower, and the target temperature requirement is cooling as an example, the temperature change Q cooling =Q Pcool +Q bcooz +Q ecool For example, Q Pcool is the compressor cooling capacity, Q bcool is the cooling capacity of the blower, Q ecool is the evaporator cooling capacity, wherein the second constraint is used to limit the cooling capacity of the compressor when it operates at the target working power to be lower than the Q cooling , limiting the cooling capacity of the evaporator when it operates at the target working power to be lower than the Q cooling , limiting the cooling capacity of the blower when operating at the target working power to be lower than the Q cooling , and the cooling capacity is positive when the compressor, evaporator and blower operate at the target working power.
[0063] In some examples, in order to prevent the working power of the temperature control device from increasing infinitely (or decreasing infinitely) during the process of optimizing the working power of the temperature control device, the present application will also set a third constraint condition, which is used to constrain the minimum value and / or maximum value of the working power of each temperature control device.
[0064] The present application will also calculate the target Hamiltonian according to the first constraint and the second constraint to obtain the target operating power of each temperature control device. Specifically, if the final state is free, the co-state vector λ must satisfy the transversal condition at the final time T: (x(T), P in (T), P e (T), P b (T), λ(T)) = 0 If the final state is fixed, then the co-state vector λ at the final time T should also satisfy:
[0065] According to the technical solution provided in the embodiment of the present application, a first constraint is determined according to the target Hamiltonian, and a second constraint is generated according to the correspondence between each temperature regulating device and the target temperature requirement; according to the first constraint and the second constraint, the target Hamiltonian is calculated to obtain the target operating power of each temperature regulating device. The above steps realize the optimization of the operating power of each temperature regulating device, save system resources, and enable the cooling capacity or heating capacity of the optimized temperature regulating device to meet the target temperature requirement, thereby ensuring that the target temperature requirement of the vehicle is met, and avoiding the problem in the related art that power consumption is not considered when the vehicle is temperature regulated, resulting in high power consumption and waste of system resources for temperature regulation; the present application optimizes the power distribution of the compressor, fan and blower through a rule-based method and a PMP (Pontryagin's Minimum Principle) method, so that the vehicle minimizes energy consumption (power minimization) while meeting the target temperature requirement; the energy efficiency ratio (COP) is improved: the optimized system can better utilize each unit input power to generate more cooling capacity, thereby improving the overall energy efficiency ratio. Enhanced system stability: More precise temperature control: The rule-based method dynamically adjusts the compressor power by real-time monitoring of the deviation between the in-car temperature and the target temperature, making the in-car temperature more stable and improving the comfort of passengers; Strong environmental adaptability: The system can automatically adjust the power of the fan and blower according to external conditions such as ambient temperature and vehicle speed to ensure the best cooling effect in different environments. Improved user experience and improved comfort: By dynamically adjusting the air volume of the blower, a more comfortable riding environment is provided according to the comfort of the passengers and the in-car temperature; Reduced noise: The optimized system can reduce unnecessary high-power operation while ensuring the cooling effect, thereby reducing noise and improving the riding experience. Reduced maintenance costs: Extended equipment life: By reasonably allocating the power of each component, the excessive use and wear of the equipment is reduced, the service life of the equipment is extended, and the maintenance cost is reduced; Reduced failure rate: The optimized system operates more stably, reduces failures caused by overload or improper operation, and further reduces the frequency and cost of maintenance.
[0066] In some embodiments, Figure 5 As shown, the target temperature requirement of the vehicle is obtained, including:
[0067] S501, obtaining the vehicle's fresh air heat load, enclosure structure heat load, vehicle occupant heat load, solar radiation heat load, and vehicle equipment heat load;
[0068] S502. Determine the target temperature requirement of the vehicle according to the vehicle's fresh air heat load, enclosure structure heat load, vehicle occupant heat load, solar radiation heat load, and vehicle equipment heat load.
[0069] Under normal operating conditions, the heat load of vehicles (including passenger cars, commercial vehicles and rail vehicles) mainly comes from five aspects: fresh air heat load Q f , heat load of enclosure structure Q d 、 Heat load of passengers in the car Q p , Solar radiation heat load (environmental heat load) Q e 、In-vehicle equipment heat load Q s .
[0070] Based on the above principle, in order to achieve cooling of the vehicle, the temperature change must be able to cover the heat load within the volume. Therefore, the target temperature requirement of the vehicle = Q f +Q d +Q p +Q e +Q s .
[0071] It can be understood that when the ambient temperature is low and the vehicle needs to be heated, the target heating amount of the vehicle = Q f +Q d -Q p -Q e -Q s .
[0072] According to the technical solution provided in the embodiment of the present application, the vehicle's fresh air heat load, enclosure heat load, occupant heat load, solar radiation heat load, and in-vehicle equipment heat load are obtained; the vehicle's target temperature requirement is determined based on the vehicle's fresh air heat load, enclosure heat load, occupant heat load, solar radiation heat load, and in-vehicle equipment heat load. The above steps are combined with the vehicle's heat load to determine the vehicle's target temperature requirement, thereby achieving accurate acquisition of the target temperature requirement.
[0073] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.
