[0001] This application relates to the field of vehicle technology, specifically to a method, apparatus, electronic device, readable storage medium, and computer program product for cooling control of an all-in-one assembly. Background Technology

[0002] When a vehicle is in motion, its powertrain and transmission systems continuously generate a significant amount of heat. If this heat cannot be dissipated effectively and promptly, the system's safety performance will be seriously threatened, making effective cooling crucial. Currently, the three-in-one electric drive cooling method is widely used for cooling vehicle powertrain and transmission systems. This method primarily focuses on cooling the motor, electronic control unit, gearbox, and related accessories. In terms of cooling flow planning, it prioritizes the heat dissipation needs of the motor, electronic control unit, and gearbox to ensure the system can operate stably. However, as vehicle electrical systems become increasingly complex, the existing three-in-one electric drive cooling solution has revealed significant shortcomings. It struggles to simultaneously handle PTC control and AHF (Automatic High-Frequency) functions, failing to achieve the optimal flow rate for the entire vehicle, thus reducing its driving range. Summary of the Invention

[0003] In view of the above problems, this application provides an all-in-one assembly cooling control method, device, electronic device, readable storage medium and computer program product, which can solve the problem that it is difficult to simultaneously take into account PTC control and AHF function, and thus cannot achieve the optimal flow request of the whole vehicle, thereby reducing the driving range of the whole vehicle.

[0004] In a first aspect, this application provides a method for cooling control of an all-in-one assembly, including: Acquire temperature detection data and system status signals of components to be cooled in the all-in-one assembly; The current operating mode is determined based on the system status signal; Based on the current operating mode and the temperature detection data, determine the target coolant flow rate to be requested; The cooling system is controlled according to the target coolant flow rate to perform corresponding cooling operations on the components to be cooled.

[0007] In the above technical solution, the method can comprehensively and accurately obtain various temperature information of key components to be cooled in the all-in-one assembly, providing a reliable basis for subsequent precise control of cooling operations.

[0008] In some implementations, determining the current operating mode based on the system status signal includes: When it is determined from the system status signal that the electronic control is not in a stall state, not in an ASC state, not in a battery heating state, and no temperature sensor is in a fault state, the current working mode is determined to be the first mode. When it is determined from the system status signal that the electronic control is in a stalled state, the current working mode is determined to be the second mode; When the system status signal indicates that the electronic control is in ASC state, the current operating mode is determined to be the third mode. When it is determined from the system status signal that the electronic control is in the battery heating state, the current working mode is determined to be the fourth mode; When it is determined from the system status signal that a temperature sensor is in a faulty state, the current working mode is determined to be the fifth mode; When an over-temperature fault is determined based on the system status signal, the current operating mode is set to the sixth mode.

[0009] In the above technical solution, the method can accurately divide multiple different working modes according to the system status signal to adapt to the operating requirements of the all-in-one assembly under various complex working conditions, thereby facilitating the subsequent targeted determination of the target coolant flow rate.

[0010] In some implementations, determining the target coolant flow rate to be requested based on the current operating mode and the temperature detection data includes: When the current working mode is the first mode or the second mode, the flow rate level judgment condition is obtained; wherein, the flow rate level judgment condition includes at least the coolant water temperature judgment condition, the electronic control module NTC temperature judgment condition, the DC / DC power transistor NTC temperature judgment condition, the OBC power transistor NTC temperature judgment condition, the PTC power transistor NTC temperature judgment condition, and the motor temperature judgment condition. The target flow rate level is determined based on the temperature detection data and the flow rate level determination criteria. The target coolant flow rate to be requested is determined based on the target flow rate level.

[0011] In the above technical solution, the method can combine different working modes, use comprehensive and detailed flow level judgment conditions and real-time temperature detection data to accurately determine the target flow level, and then accurately obtain the target coolant flow rate to be requested, so as to achieve fine control of the coolant flow rate of the multi-in-one assembly.

[0012] In some implementations, determining the target coolant flow rate to be requested based on the current operating mode and the temperature detection data includes: When the current working mode is the third mode, the target coolant flow rate is determined to be the first preset flow rate; When the current working mode is the fourth mode, the target coolant flow rate is determined to be the second preset flow rate; When the current working mode is the sixth mode, the target coolant flow rate is determined to be the third preset flow rate.

[0013] In the above technical solution, the method can quickly determine the target coolant flow rate directly based on the preset flow rate for a variety of specific working modes, simplifying the flow rate determination process and improving the cooling control response speed.

[0014] In some implementations, determining the target coolant flow rate to be requested based on the current operating mode and the temperature detection data includes: When the current working mode is the fifth mode, and the coolant temperature sensor is not faulty, the electronic control module NTC is not faulty, the DC / DC power transistor NTC is not faulty, the OBC power transistor NTC is not faulty, and the PTC power transistor NTC is not faulty, the flow rate level judgment condition of the first mode is obtained. Based on the temperature detection data and the flow rate level determination conditions, the target flow rate level is determined; and based on the target flow rate level, the target coolant flow rate to be requested is determined.

[0015] In the above technical solution, the method can reuse the flow rate judgment logic of the first mode under the specific condition that the fifth mode (temperature sensor failure mode) and the key temperature sensors are all fault-free, so as to accurately determine the target flow rate and coolant flow rate by combining real-time temperature detection data.

[0016] In some implementations, determining the target coolant flow rate to be requested based on the current operating mode and the temperature detection data includes: When the current working mode is the fifth mode, and the coolant temperature sensor is faulty, the target coolant flow rate is determined to be the fourth preset flow rate. When the current working mode is the fifth mode, if the coolant temperature sensor is not faulty, the NTC electronic control module is faulty, and the motor controller is in normal working condition, the target coolant flow rate is determined to be the fifth preset flow rate. When the current working mode is the fifth mode, and the coolant temperature sensor is not faulty, the electronic control module NTC is not faulty, the DC / DC power transistor NTC is faulty, and the DC / DC converter is in normal working condition, the target coolant flow rate is determined to be the sixth preset flow rate. When the current working mode is the fifth mode, and the coolant temperature sensor is not faulty, the electronic control module NTC is not faulty, the DC / DC power transistor NTC is not faulty, the OBC power transistor NTC is faulty, and the charger is in normal working condition, the target coolant flow rate is determined to be the seventh preset flow rate.

[0017] In the above technical solution, the method can accurately match and determine the appropriate preset flow rate as the target coolant flow rate under the fifth mode (temperature sensor failure mode) for different fault combinations of coolant temperature sensor and other types of key power transistor NTC sensors, combined with the working status of the corresponding components.

[0018] In some implementations, determining the target coolant flow rate to be requested based on the current operating mode and the temperature detection data includes: When the current working mode is the fifth mode, if the coolant temperature sensor is not faulty, the NTC electronic control module is faulty, and the motor controller is not in normal working condition, the flow level judgment condition of the first mode or the second mode is obtained. The target judgment condition is obtained by deleting the NTC temperature judgment condition from the flow rate level judgment condition. Based on the temperature detection data and the target judgment conditions, the target flow rate level is determined, and the target coolant flow rate to be requested is determined based on the target flow rate level.

[0019] In the above technical solution, the method can use the flow level judgment logic of the first or second mode in the fifth mode and the NTC of the electronic control module is faulty or the motor controller is not working properly. By accurately eliminating the judgment conditions related to the fault, the method generates the target judgment conditions that are suitable for the current working conditions, and then reasonably determines the target flow level and coolant flow.

[0020] In some implementations, determining the target coolant flow rate to be requested based on the current operating mode and the temperature detection data includes: When the current working mode is the fifth mode, if the coolant temperature sensor is not faulty, the electronic control module NTC is not faulty, the DC / DC power transistor NTC is faulty, and the DC / DC converter is not in normal working state, the flow level judgment condition of the first mode or the second mode is obtained. The target judgment condition is obtained by deleting the DC / DC power transistor NTC temperature judgment condition from the flow rate level judgment condition. Based on the temperature detection data and the target judgment conditions, the target flow rate level is determined, and the target coolant flow rate to be requested is determined based on the target flow rate level.

[0021] In the above technical solution, the method can use the flow rate level judgment method of the first or second mode in the fifth mode and under the conditions of DC / DC power tube NTC failure and DC / DC converter abnormal operation. By selectively deleting the judgment conditions related to the faulty component, the method constructs the target judgment conditions that conform to the current actual working conditions, thereby accurately determining the target flow rate level and coolant flow rate.

[0022] In some implementations, determining the target coolant flow rate to be requested based on the current operating mode and the temperature detection data includes: When the current working mode is the fifth mode, if the coolant temperature sensor is not faulty, the electronic control module NTC is not faulty, the DC / DC power transistor NTC is not faulty, the OBC power transistor NTC is faulty, and the charger is not in normal working state, the flow level judgment condition of the first mode or the second mode is obtained.

Based on the temperature detection data and the target judgment conditions, the target flow rate level is determined, and the target coolant flow rate to be requested is determined based on the target flow rate level.

[0023] In the above technical solution, the method can accurately determine the target flow level and the target coolant flow rate by using the mature flow level judgment logic of the first or second mode in the fifth mode and under the conditions of OBC power tube NTC failure and abnormal charger operation. By accurately eliminating the OBC power tube NTC temperature judgment conditions related to the faulty component, the method can accurately determine the target flow level and the target coolant flow rate.

[0025] In the above technical solution, the method can use the existing flow level judgment method of the first or second mode in the fifth mode and under the conditions of PTC power tube NTC failure and electric heater abnormal operation. By accurately removing the PTC power tube NTC temperature judgment condition associated with the faulty component, the method can construct a target judgment condition that is suitable for the current actual working condition, thereby accurately determining the target flow level and the target coolant flow rate.

[0038] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0039] Most existing integrated electric drive systems are three-in-one electric drives, mainly consisting of a motor, electronic control system, gearbox, and related accessories. Typically, the corresponding flow requests only consider cooling for the motor system, electronic control system, and gearbox.

[0040] However, when considering PTC control and AHF functionality, flow requests become more complex, requiring consideration not only of conventional motor and electronic control cooling, but also power system cooling and heat transfer during PTC and AHF control. Therefore, existing methods are insufficient to handle this complex all-in-one cooling scenario.

[0041] To address the aforementioned technical problems, this application provides a method for cooling control of an all-in-one assembly. This method clearly identifies the components corresponding to the cooling control of the all-in-one assembly, including the electronic control unit, motor, DC-DC converter, OBC, and PTC. It then determines the required flow rate for each component under the current operating conditions based on its original flow request strategy, sends a flow request message to the vehicle, and performs cooling control according to the highest flow request among all components. Specifically, this method determines the corresponding flow request based on temperature sensors and system status; this flow request is divided into five levels based on the characteristics of the water pump.

[0042] Based on this, the method can determine the accurate flow request based on the all-in-one integrated electric drive system, thereby realizing the coupling between cooling and heat transfer. Under the premise of meeting the cooling and heat transfer requirements, the optimal flow request of the whole vehicle is achieved, thus achieving the optimal driving range of the whole vehicle.

[0043] like Figure 1 As shown, some embodiments of this application provide a cooling control method for an all-in-one assembly, the cooling control method for the all-in-one assembly including: S101.

Determine the target coolant flow rate to be requested based on the current operating mode and temperature detection data; S104. Control the cooling system to perform corresponding cooling operations on the components to be cooled based on the target coolant flow rate.

[0044] In some embodiments, the all-in-one assembly is a core component of the powertrain system of new energy vehicles, including key functional modules such as integrated controller, motor, differential reducer, DC-DC converter, OBC, and PTC control loop, forming a compact electromechanical coupling system. Its design goals are to improve energy conversion efficiency, optimize space layout, reduce manufacturing costs, and meet the requirements for lightweighting the entire vehicle.

[0045] In some embodiments, the system status signals mainly include Rdy indicator light signals, motor and controller temperature signals, rotor position signals, voltage and current signals, fault diagnosis signals, and operating mode switching signals, which together constitute the status monitoring and control system of the electric drive system.

[0046] In the above embodiments, the method can accurately determine the current operating mode of the vehicle based on the AHF function (Advanced Hybrid Function), and determine the optimal flow request of the whole vehicle while taking into account the PTC control in the vehicle, so as to carry out effective cooling operation.

[0047] In some embodiments, the component to be cooled includes at least a motor controller, a drive motor, a DC / DC converter, a charger, and an electric heater; Temperature detection data should include at least the motor temperature of the drive motor, the electrical control temperature of the motor controller, the electric heater temperature of the electric heater, the coolant temperature, the charger temperature of the charger, and the converter temperature of the DC / DC converter.

[0048] In the above embodiments, the method can comprehensively and accurately obtain various temperature information of key components to be cooled in the all-in-one assembly, providing a reliable basis for subsequent precise control of cooling operations.

[0049] In some embodiments, determining the current operating mode based on system status signals includes: When the system status signal determines that the electronic control is not in a stall state, not in an ASC state, not in a battery heating state, and no temperature sensor is in a fault state, the current working mode is determined to be the first mode. When the system status signal indicates that the electronic control is in a stalled state, the current operating mode is determined to be the second mode. When the system status signal indicates that the electronic control is in ASC state, the current operating mode is determined to be the third mode. When the system status signal indicates that the electronic control is in battery heating mode, the current working mode is determined to be the fourth mode. When the system status signal indicates that a temperature sensor is in a faulty state, the current working mode is determined to be the fifth mode. When an over-temperature fault is determined based on the system status signal, the current operating mode is set to the sixth mode.

[0050] In some embodiments, the first mode refers to the normal operating state. In the normal operating state, the electronic control is not in the second or third mode, and the whole machine is not in the fourth mode. At this time, the method can determine the requested flow rate according to the temperature sensor threshold range. The requested flow rate levels are: 0L / min, 2L / min, 4L / min, 6L / min, and 8L / min.

[0051] In some embodiments, the second mode refers to the electronic control being in a stalled state (the electronic control is in torque control state and the output frequency is <5Hz). In this case, the method can determine the requested flow rate based on the temperature sensor threshold range, and the requested flow rate levels are: 2L / min, 4L / min, 6L / min, and 8L / min.

[0052] In some embodiments, the third mode refers to the electronic control being in ASC state. In this case, the method can directly request 8L / min.

[0053] In some embodiments, the fourth mode refers to the electronic control being in a battery heating state. In this case, the method can directly request 10L / min.

[0054] In some embodiments, the fifth mode refers to a situation where any temperature sensor used for coolant flow request determination is in a faulty state (coolant temperature sensor fault). In this case, the method can directly request 8 L / min. The fifth mode can correspond to: PTC power transistor NTC fault: Determine whether the PTC is in working state (heating). If it is in working state, directly request 8L / min; if it is not in working state, in the temperature judgment of the first mode, the temperature of the PTC power transistor NTC is set to invalid and does not participate in the flow request judgment. NTC (Network Control Module) Fault: Determine if the NTC is currently in operation (pipe open). If it is in operation, directly request 8L / min. If it is not in operation, in the temperature judgment of the first mode, set the temperature of the NTC to invalid and not participate in the flow request judgment. NTC fault in motor stator: Determine if the motor is in operation (pipe open). If it is in operation, directly request 8L / min. If it is not in operation, in the temperature judgment of the first mode, the temperature of the motor stator NTC is set to invalid and does not participate in the flow request judgment.

[0055] In some embodiments, the sixth mode refers to an over-temperature fault (over-temperature of the electronic control module junction). In this case, the method can directly request 8L / min.

[0056] In some embodiments, PTC is a positive temperature coefficient thermistor heating module.

[0057] In the above embodiments, the method can accurately divide multiple different working modes according to the system status signal to adapt to the operating requirements of the all-in-one assembly under various complex working conditions, thereby facilitating the subsequent targeted determination of the target coolant flow rate.

[0058] In some embodiments, determining the target coolant flow rate to be requested based on the current operating mode and temperature detection data includes: When the current working mode is the first mode or the second mode, obtain the flow rate level judgment condition; among which, the flow rate level judgment condition includes at least the coolant water temperature judgment condition, the electronic control module NTC temperature judgment condition, the DC / DC power transistor NTC temperature judgment condition, the OBC power transistor NTC temperature judgment condition, the PTC power transistor NTC temperature judgment condition, and the motor temperature judgment condition. Determine the target flow rate level based on temperature detection data and flow rate setting criteria; Determine the target coolant flow rate to be requested based on the target flow rate level.

[0059] For example, target traffic levels include: Gear 0: Request coolant flow rate of 0 L / min; Gear 1: Request coolant flow rate of 2L / min; Gear 2: Request coolant flow rate of 4L / min; Gear 3: Request coolant flow rate of 6L / min; Gear 4: Request coolant flow rate of 8L / min; Gear 5: Request coolant flow rate of 10L / min.

[0060] For example, Figure 2 The diagram illustrates an adjustment procedure for the target flow rate setting in either the first or second mode. Here, Tw represents the coolant temperature; Tw1 represents the first coolant temperature threshold; Tw2 represents the second coolant temperature threshold; and Tw3 represents the third coolant temperature threshold. DetT is the hysteresis temperature; Tinv_ntc is the controller temperature; Tinv_ntc1 is the first controller temperature threshold; Tinv_ntc2 is the second controller temperature threshold; Tinv_ntc3 is the third controller temperature threshold; Tdcdc_ntc is the DC-DC converter temperature; Tdcdc_ntc1 is the first DC-DC temperature threshold; Tdcdc_ntc2 is the third DC-DC temperature threshold; Tdcdc_ntc3 is the third DC-DC temperature threshold.

Tmt is the motor temperature; Tmt1 is the first motor temperature threshold; Tmt2 is the second motor temperature threshold; and Tmt3 is the third motor temperature threshold.

[0061] In the above embodiments, the method can combine different working modes, utilize comprehensive and detailed flow level judgment conditions and real-time temperature detection data to accurately determine the target flow level, and then accurately obtain the target coolant flow rate to be requested, thereby achieving fine control of the coolant flow rate of the multi-in-one assembly.

[0062] In some embodiments, determining the target coolant flow rate to be requested based on the current operating mode and temperature detection data includes: When the current working mode is the third mode, the target coolant flow rate is determined to be the first preset flow rate; When the current working mode is the fourth mode, the target coolant flow rate is determined to be the second preset flow rate; When the current operating mode is the sixth mode, the target coolant flow rate is determined to be the third preset flow rate.

[0063] For example, the first preset flow rate is 8L / min; the second preset flow rate is 10L / min; and the third preset flow rate is 8L / min.

[0064] In the above embodiments, the method can quickly determine the target coolant flow rate directly based on the preset flow rate for a variety of specific working modes, simplifying the flow rate determination process and improving the cooling control response speed.

[0065] In some embodiments, determining the target coolant flow rate to be requested based on the current operating mode and temperature detection data includes: When the current working mode is the fifth mode, and the coolant temperature sensor is not faulty, the NTC of the electronic control module is not faulty, the NTC of the DC / DC power transistor is not faulty, the NTC of the OBC power transistor is not faulty, and the NTC of the PTC power transistor is not faulty, the flow level judgment condition of the first mode is obtained. Based on temperature detection data and flow rate threshold judgment conditions, determine the target flow rate threshold; and based on the target flow rate threshold, determine the target coolant flow rate to be requested.

[0066] In the above embodiments, the method can reuse the flow rate judgment logic of the first mode under the specific condition of the fifth mode (temperature sensor failure mode) and the key temperature sensors are all without failure, so as to accurately determine the target flow rate and coolant flow rate by combining real-time temperature detection data.

[0067] In some embodiments, determining the target coolant flow rate to be requested based on the current operating mode and temperature detection data includes: When the current working mode is the fifth mode, if the coolant temperature sensor malfunctions, the target coolant flow rate is determined to be the fourth preset flow rate; When the current working mode is the fifth mode, and the coolant temperature sensor is not faulty, the NTC electronic control module is faulty, and the motor controller is in normal working condition, the target coolant flow rate is determined to be the fifth preset flow rate. When the current working mode is the fifth mode, and the coolant temperature sensor is not faulty, the NTC of the electronic control module is not faulty, the NTC of the DC / DC power transistor is faulty, and the DC / DC converter is in normal working condition, the target coolant flow rate is determined to be the sixth preset flow rate. When the current working mode is the fifth mode, and the coolant temperature sensor is not faulty, the electronic control module NTC is not faulty, the DC / DC power transistor NTC is not faulty, the OBC power transistor NTC is faulty, and the charger is in normal working condition, the target coolant flow rate is determined to be the seventh preset flow rate.

[0068] In some embodiments, when the PTC power transistor NTC fails, it is determined whether the PTC is in working state (heating). If it is in working state, a request for 8L / min is directly made. If it is not in working state, the temperature of the PTC power transistor NTC is set to invalid in the temperature judgment of the first mode and is not included in the flow request judgment. In some embodiments, when the NTC (Network Control Module) fails, it is determined whether the NTC is in the working state (pipe open). If it is in the working state, a request for 8L / min is made directly. If it is not in the working state, the temperature of the NTC is set to invalid in the temperature judgment of the first mode and is not included in the flow request judgment. In some embodiments, when the stator NTC of the electric control unit fails, it is determined whether the electric control unit is in the working state (pipe open).
