Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to a vehicle, energy management system, method, electronic device, and storage medium. Background Technology

[0002] In the field of vehicle electric drive thermal management, especially in hybrid or pure electric vehicles operating in low-temperature environments, the lubricating oil in components such as gearboxes and bearings becomes viscous, increasing viscous resistance and reducing the system efficiency of the electric drive assembly. Therefore, it is generally necessary to improve the system efficiency of the electric drive assembly to improve low-temperature range performance.

[0003] To meet the above requirements, related technologies often employ a wax-type temperature control valve installed on the oil circuit side of the oil cooler. Its working principle is generally as follows: a wax-type temperature sensing element detects the oil temperature. When the oil temperature is below a preset threshold, the heat exchange fluid is isolated from the oil, causing the oil to store heat and its temperature to rise, thus maintaining its own temperature within the closed oil circuit. When the oil temperature reaches the threshold, the temperature control valve opens, and the heat exchange fluid and oil exchange heat inside the heat exchanger.

[0004] The aforementioned control method is constrained by the inherent material response characteristics of the wax element. Its switching action relies entirely on passive triggering by changes in oil temperature. Once the opening temperature is calibrated, it cannot be flexibly adjusted according to real-time operating conditions. Furthermore, the valve core is driven by oil temperature to lift and fall, resulting in a significant lag in response speed. This passive control logic prevents active intervention in the heat exchange between the heat exchange fluid and the oil, making it difficult to effectively improve the drive efficiency of the electric drive assembly.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Exemplary Implementation Environment According to the energy management system of this application embodiment, see [link to relevant documentation]. Figure 1 The system includes: electric drive system circuit 1, intercooler circuit 2, thermal management circuit 3, first flow regulation mechanism 4, and controller; One end of the thermal management circuit is connected to the first flow regulating mechanism, and the other end is connected to the first end of the electric drive system circuit; One end of the intercooler circuit is connected to the first flow regulating mechanism, and the other end is connected to the second end of the electric drive system circuit; The first flow regulating mechanism is also connected to the second end of the electric drive system circuit; The thermal management circuit is used for heat exchange between the electric drive system circuit and the intercooler circuit; The controller is used to acquire first thermal demand information of the intercooler circuit and second thermal demand information of the electric drive system circuit; based on the first thermal demand information and the second thermal demand information, it controls the opening degree of the first flow regulation mechanism and / or the flow rate of the thermal management circuit.

[0028] In some embodiments, the intercooler circuit includes an engine intercooler (or a water-charged air cooler (WCAC)) for cooling the engine's turbocharged intake air. The intercooler circuit may also include a cooling fan for dissipating heat from the engine. The thermal management circuit provides power and cooling capacity for coolant circulation and includes components such as a coolant pump, a radiator (or a heat exchanger coupled to a heat pump system), and a heater (for heating the coolant). The electric drive system circuit includes an oil cooler and an electric drive lubrication circuit. It is understood that the controller can switch the thermal management mode of the thermal management circuit based on the first thermal demand information and the second thermal demand information, where the management mode includes a cooling mode and a heating mode. For example, if the first and second thermal demand information indicate a cooling demand, the thermal management circuit is switched to cooling mode to cool the coolant; conversely, if the first and second thermal demand information indicate a heating demand, the thermal management circuit is switched to heating mode to heat the coolant.

[0029] The first flow regulating mechanism has at least three ports, one of which is connected to the thermal management circuit (e.g., the output port of the coolant pump), the second port is connected to the coolant outlet of the electric drive system circuit, and the third port is connected to the coolant inlet of the intercooler circuit.

[0030] The controller is electrically connected to the first flow regulating mechanism, the coolant pump, the radiator fan, and temperature sensors (e.g., detecting lubricating oil temperature, intercooler inlet coolant temperature, ambient temperature, etc.) to collect vehicle operating status information and issue control commands, such as controlling the opening degree of the first flow regulating mechanism and / or the rotational speed of the coolant pump.

[0031] The aforementioned flow regulating mechanism refers to a device or component capable of regulating the flow rate or direction of fluid flowing through it. Specifically, it can refer to a proportional valve (such as a three-way proportional valve or a four-way proportional valve) that linearly or non-linearly regulates the flow rate by changing the valve core opening; it can also refer to an on / off valve that controls the opening and closing of the flow path by means of two states: open or closed; or it can refer to a flow regulating unit consisting of a variable speed pump and one or more valves with fixed opening degrees.

[0032] For example, the first flow regulation mechanism can be a three-way proportional valve (PCTV) that proportionally distributes the coolant flow from one port to the other two ports. In another embodiment, the flow regulation function can also be achieved by combining two independent two-way proportional valves, one connected in series in the oil cooler branch and the other connected in series in the intercooler branch, indirectly achieving flow distribution by controlling the combination of their opening degrees. In some embodiments, for precise control, the response time of the flow regulation mechanism can be less than 200 milliseconds to achieve timely tracking of rapidly changing heat exchange demands.

[0033] The aforementioned heat demand information is any signal, data, or status indication used to characterize whether a component or circuit requires heat exchange (cooling or heating) and the required intensity of heat exchange. Specifically, it can be a binary request flag (such as cooling requirement or no cooling requirement); it can be a continuous or discrete value representing the intensity of the demand (such as demand flow rate level, demand heat exchange, etc.); or it can be an actual measured temperature used directly for comparison with control target values ​​(such as oil temperature, intercooler inlet water temperature).

[0034] The methods for obtaining heat demand information may include: directly reading the measured value of the temperature sensor and comparing it with a preset threshold; receiving heat exchange request signals from other control modules (such as engine control unit and motor control unit); or calculating it based on the current operating conditions (such as motor torque, speed, and ambient temperature) by looking up tables or models.

[0035] For example, the first heat demand information of the intercooler circuit can be determined by acquiring the engine inlet temperature and heat load. Based on the first correspondence between the inlet temperature and / or heat load and the heat demand information, the first heat demand information corresponding to the inlet temperature and heat load is determined. If the inlet temperature or heat load is higher than its corresponding first threshold, it indicates that the intercooler circuit has a cooling demand; if the inlet temperature or heat load is lower than its corresponding second threshold, it indicates that the intercooler circuit has a heating demand.

[0036] The second thermal demand information of the electric drive system circuit can be determined by acquiring the coolant inlet temperature and electric drive temperature of the electric drive system circuit. A second correspondence between the inlet temperature, electric drive temperature and thermal demand can be established in advance, and the second thermal demand information corresponding to the inlet temperature or electric drive temperature can be determined from this correspondence.

[0037] Furthermore, regarding the system, see [link to system]. Figure 2 It also includes a second flow regulation mechanism 5. The second flow regulating mechanism is connected to the intercooler circuit, the first end of the electric drive system circuit, and the second end of the electric drive system circuit, respectively. The controller is also configured to control the opening degree of the second flow regulating mechanism based on the first heat demand information and the second heat demand information.

[0038] In some embodiments, the second flow regulating mechanism may be, but is not limited to, a three-way proportional valve. By setting up the second flow regulating mechanism and controlling the valve opening of the second flow regulating mechanism, the flow rate of coolant flowing through the electric drive system circuit can be independently regulated.

[0039] In one specific embodiment, the energy management system of this application, see [link to relevant documentation]. Figure 2 The intercooler circuit includes the engine intercooler, the electric drive system circuit includes an oil cooler and an electric drive lubrication circuit, and a heat exchange system circuit can also be installed. This heat exchange system circuit includes a heat exchanger and a heat pump system. The thermal management circuit includes a coolant pump, a first three-way valve, and a second three-way valve. The coolant pump, the first three-way valve, and the second three-way valve are controlled by a controller. The controller controls the speed of the coolant pump and the valve openings of the first and second three-way valves based on the first and second heat demand information to meet the heat demands of the electric drive system circuit and the intercooler circuit.

[0040] The energy management system of this application achieves active control of heat exchange between the coolant and oil in the oil cooler by adding an electronic three-way proportional valve, which can rapidly increase the oil temperature; at the same time, it enables flexible control of the oil temperature, providing a prerequisite for achieving optimal control calibration of the system; it coordinates the cooling requirements of the electric drive and the cooling requirements of the engine intercooler, and formulates corresponding strategies by decomposing environmental conditions and vehicle operating conditions to achieve full-scenario coverage.

[0041] Exemplary methods Please see Figure 3 In one exemplary embodiment, an energy management method is provided, applied to a controller in the energy management system described in the above embodiments, the method comprising: Step 301: Obtain the first thermal demand information of the intercooler circuit and the second thermal demand information of the electric drive system circuit.

[0042] Step 302: Based on the first heat demand information and the second heat demand information, control the opening degree of the first flow regulation mechanism and / or the flow rate of the thermal management circuit.

[0043] In some embodiments, the methods for obtaining the first heat demand information and the second heat demand information can refer to the relevant embodiments described above, and will not be repeated here.

[0044] For example, the intercooler circuit can determine the first heat demand information through the inlet water temperature, and the electric drive system circuit can determine the second heat demand information through the oil temperature in the circuit. When the oil temperature in the electric drive system is higher than the calibrated first target value (e.g., 40 degrees Celsius), the second heat demand information is determined to be a cooling demand; when the oil temperature is lower than the calibrated second target value (e.g., 10 degrees Celsius), the second heat demand information is determined to be a heating demand. See also... Figure 4 If the second heat demand information is cooling demand, the PCTV valve (i.e., the first flow regulation mechanism) is opened to 100%, and the flow passes through path 1-2. (See also...) Figure 5 The second heat demand information is for heating demand; the PCTV valve is bypassed, with the PCTV valve opening at 0%, and the flow passes through paths 1-3. Among these... Figure 4 and Figure 5 A dashed line indicates that the coolant has not passed through, while a solid line indicates that the coolant has passed through.

[0045] In an optional embodiment, controlling the opening degree of the first flow regulation mechanism and / or the flow rate of the thermal management loop based on the first heat demand information and the second heat demand information includes: When both the first heat demand information and the second heat demand information indicate no heat demand, the connection between the first flow regulating mechanism and the intercooler circuit is disconnected. When either the first heat demand information or the second heat demand information indicates a heat demand, the opening of the first flow regulation mechanism is controlled to meet the target heat demand information and / or the flow of the heat management circuit is controlled to meet the target heat demand information, wherein the target heat demand information is the heat demand information that has a heat demand in the first heat demand information and the second heat demand information. When both the first heat demand information and the second heat demand information indicate heat demand, the maximum heat demand information is determined, and the opening degree of the first flow regulation mechanism is controlled to meet the maximum heat demand information and / or the flow rate of the thermal management loop is controlled to meet the maximum heat demand information.

[0046] In some embodiments, the thermal demands of the intercooler circuit and the electric drive system circuit may differ during the operation of the energy management system. Based on the actual thermal demands of the two circuits, the following control strategies can be adopted.

[0047] If both the first and second heat demand information indicate no heat demand, meaning both the intercooler circuit and the electric drive system circuit indicate no heat demand, then the connection between the first flow regulating mechanism and the intercooler circuit is disconnected (for example, see...). Figure 5 (When the 1-3 passages of the PCTV valve are open), the coolant mainly bypasses the oil cooler.

[0048] If any of these indicators indicate a heat demand, the opening of the first flow regulation mechanism is controlled to meet the target heat demand information, and / or the flow rate of the thermal management circuit is controlled to meet the target heat demand information. For example, when only the electric drive system circuit has a cooling demand, see [reference needed]. Figure 4 Control the opening of the PCTV valve's 1-2 passages to meet the cooling demand, and appropriately increase the water pump speed. If both indicate a heat demand and a cooling demand, determine the maximum heat demand information between the two; see [link to relevant documentation]. Figure 4 Then, control the opening of the PCTV valve 1-2 passage and / or the flow rate of the thermal management circuit to meet this maximum heat demand information. For example, if both require high-flow-rate cooling, open the PCTV valve 1-2 passage to its maximum and simultaneously turn the coolant pump to its highest setting to provide maximum system cooling capacity. If both indicate a heat demand and a temperature rise requirement, see [reference needed]. Figure 5 This controls the conduction of passages 1-3 of the PCTV valve.

[0049] In an optional embodiment, in order to prioritize the needs of one party (especially the cooling demand party) while also taking into account the special needs of the other party (such as anti-condensation), this application also provides a heat compensation mechanism. The energy management method further includes: Thermal compensation is performed on the target circuit, which includes the electric drive system circuit or the intercooler circuit that has no heat requirement or the minimum cooling requirement.

[0050] In some embodiments, when the thermal requirements of the intercooler circuit and the electric drive system circuit are different, thermal compensation of the target circuit can prevent the target circuit from being affected by cooling.

[0051] For example, in a high-speed driving scenario in rainy weather, the electric drive system circuit has a significant cooling demand due to continuous high load operation (i.e., strong second heat demand information). Meanwhile, the intercooler circuit, due to high ambient humidity and low intake air temperature, primarily needs to prevent its surface temperature from falling below the dew point and causing condensation (the first heat demand information indicates "small flow cooling or anti-condensation demand," meaning the demand intensity is weak but exists). In this situation, if the maximum demand principle is simply applied, requesting a large flow of coolant to cool the electric drive system circuit, the coolant flow through the intercooler circuit would also be large, potentially causing the intercooler circuit temperature to drop too low, leading to a risk of condensation. To resolve this conflict, the controller prioritizes meeting the oil cooler's flow demand by adjusting the opening of the first flow regulation mechanism, while simultaneously initiating heat compensation for the intercooler circuit to ensure its normal operation.

[0052] In one optional embodiment, thermal compensation of the target loop includes at least one of the following: The heat dissipation capacity of the heat dissipation unit in the target circuit is reduced. Control the target vehicle using the energy management system to reduce its speed; The exhaust gas recirculation system in the target vehicle is shut down.

[0053] In some embodiments, the heat dissipation unit may include a cooling fan and an active air intake grille. The fan speed can be reduced and / or the opening of the active air intake grille can be decreased to reduce heat dissipation intensity, thereby increasing the base temperature of the coolant flowing back to the coolant pump. Thus, even if the flow rate through the target circuit is large, its inlet water temperature will increase due to the reduced heat dissipation intensity, thereby reducing the risk of condensation.

[0054] Alternatively, the target vehicle using the energy management system can be controlled to reduce its speed. Reducing speed decreases the impact of high-speed airflow, indirectly increasing the temperature of the intercooler surface and also helping to prevent condensation.

[0055] Alternatively, the exhaust gas recirculation (EGR) system in the target vehicle can be shut off. Shutting off EGR reduces the amount of cold exhaust gas entering the engine, helping to increase intake air temperature and indirectly alleviating the problem of low-temperature condensation on the intercooler surface.

[0056] The aforementioned compensation methods can be implemented in sync with flow allocation control. Through multi-dimensional adjustments, the needs of both parties can be met in a coordinated manner under conflicting conditions, thereby enabling a highly intelligent and global control strategy.

[0057] In an optional embodiment, the energy management system further includes a second flow regulation mechanism, wherein controlling the opening degree of the first flow regulation mechanism and / or the flow rate of the thermal management loop based on the first heat demand information and the second heat demand information includes: The opening degree of the first flow regulation mechanism is controlled to meet the first heat demand information; The opening degree of the second flow regulation mechanism is controlled to meet the second heat demand information; When the second heat demand information is greater than the first heat demand information, the opening degree of the first flow regulating mechanism is controlled to meet the second heat demand information.

[0058] In some embodiments, the electric drive system circuit and the intercooler circuit in the energy management system can control the condensate flow rate of each by controlling the opening of the first flow regulating mechanism and the second flow regulating structure, respectively, so as to meet their respective heat requirements.

[0059] For example, see Figure 2According to the first heat demand information, the first flow regulating mechanism 1-2 is controlled to be open, and its opening degree is controlled according to the first heat demand information. If the second heat demand information is no heat demand, the second flow regulating mechanism 4-6 is controlled to be open, and the coolant directly bypasses the electric drive system circuit without cooling it. If the second heat demand information is heat demand, the second flow regulating mechanism 4-5 is controlled to be open, and its opening degree is controlled to meet the second heat demand information. Since the coolant first flows through the intercooler circuit and then through the electric drive system circuit, when the second heat demand information is greater than the first heat demand information, the opening degree of the first flow regulating mechanism 1-2 and the opening degree of the second flow regulating mechanism 4-5 can be controlled to meet the second heat demand information, thereby meeting the heat demand of the electric drive system circuit. The intercooler circuit can meet its heat demand through thermal compensation.

[0060] The energy management method of this application adopts an electronic three-way proportional valve, which has higher control flexibility and faster response, and can realize fine control of the electric drive active heat storage function. From the perspective of vehicle energy management, it comprehensively considers the constraints of reducing drive power consumption and reducing heat pump power consumption, and can achieve optimal control of vehicle energy consumption through system calibration. The requirements of engine intercooler anti-condensation and electric drive active heat storage are coordinated and controlled to achieve high integration and full-scenario coverage in control.
