[0045] For the range extender assembly, regardless of whether the crankshaft direct-connected generator is integrated with a generator controller (GCU), the cooling system of the generator and the GCU generally adopts a series control form. Since the power limit temperature of the GCU is much lower than that of the generator, the series structure of cooling the GCU first and then the generator has a long water channel and a large flow resistance, which cannot reduce the energy consumption of the vehicle's electronic water pump; the inability to control the temperature separately in different zones and the inability to perform graded cooling results in low efficiency and energy waste of the motor's electronic control cooling system.

[0046] Based on the above problems, the embodiments of the present application propose a thermal management control method, device, system, storage medium and vehicle controller, which help to solve the problems of low efficiency and high energy consumption of the cooling system of the generator and generator controller.

[0047] Figure 1 This is a schematic diagram of the structure of the thermal management control device provided in the embodiment of the present application. Figure 1 As shown, the thermal management control device includes a first three-way valve 12 and a second three-way valve 15, a generator controller (GCU) 13 and a generator 14, and a pipeline system, including a first pipeline 101, a second pipeline 102, a third pipeline 103, a fourth pipeline 104 and a fifth pipeline 105. Among them, the generator controller (GCU) 13 is connected in series between the first three-way valve 12 and the second three-way valve 15, and the generator controller (GCU) 13 is connected to the first three-way valve 12 through the first pipeline 101, and the generator controller (GCU) 13 is connected to the second three-way valve 15 through the second pipeline 102; the generator 14 is connected in series between the first three-way valve 12 and the second three-way valve 15, and the generator 14 is connected to the first three-way valve 12 through the third pipeline 103, and the generator 14 is connected to the second three-way valve 15 through the fourth pipeline 104; the generator controller (GCU) 13 and the generator 14 are connected through the fifth pipeline 105.

[0048] In some embodiments, the first three-way valve 12 includes a first water inlet 121 , a first water outlet 122 , and a second water outlet 123 , and the second three-way valve 15 includes a second water inlet 152 , a third water inlet 153 , and a third water outlet 151 .

[0049] The first water inlet 121 is connected to the first water outlet 122, the second water inlet 152 is connected to the third water outlet 151, and the third pipeline 103 is connected to the fourth pipeline 104, that is, the first three-way valve 12, the third pipeline 103, the fourth pipeline 104 and the second three-way valve 15 are connected, thereby forming a separate cooling circuit for the generator.

[0050] The first water inlet 121 is connected to the second water outlet 123, the third water inlet 153 is connected to the third water outlet 151, and the first pipeline 101 and the second pipeline 102 are connected, that is, the first three-way valve 12, the first pipeline 101, the second pipeline 102 and the second three-way valve 15 are connected, thereby forming a separate cooling circuit for the GCU.

[0051] The first water inlet 121 is connected to the second water outlet 123, the second water inlet 152 is connected to the third water outlet 151, the first pipeline 101, the fifth pipeline 105 and the fourth pipeline 104 are connected, that is, the first three-way valve 12, the first pipeline 101, the fifth pipeline 105, the fourth pipeline 104 and the second three-way valve 15 are connected, thereby forming a series cooling circuit between the GCU and the generator, and the GCU is cooled preferentially.

[0052] The first water inlet 121 is connected to the first water outlet 122, the third water inlet 153 is connected to the third water outlet 151, the third pipeline 103, the fifth pipeline 105 and the second pipeline 102 are connected, that is, the first three-way valve 12, the third pipeline 103, the fifth pipeline 105, the second pipeline 102 and the second three-way valve 15 are connected, thereby forming a series cooling circuit between the GCU and the generator, and the generator is cooled first.

[0053] Optionally, the thermal management control device further includes an electronic water pump 11 and a radiator 16, wherein the electronic water pump 11 is connected to the water inlet (first water inlet 121) of the first three-way valve 12, the radiator 16 is connected to the water outlet (third water outlet 151) of the second three-way valve, and the electronic water pump 11 and the radiator 16 are connected in series between the first three-way valve 12 and the second three-way valve 15. The radiator 16 is used to cool the liquid in the pipeline loop, and the electronic water pump 11 provides circulation power for the liquid in the entire pipeline loop.

[0054] Optionally, the thermal management control device may further include an expansion kettle 17, wherein the expansion kettle 17 is used to store water, and the electronic water pump 11 is connected to the expansion kettle 17 to transport water flowing out of the expansion kettle. Figure 2 The schematic diagram of the thermal management control method provided in the embodiment of the present application specifically includes the following steps:

[0055] Step S21, determining the working state of a temperature sensor, wherein the temperature sensor is used to detect the actual temperature of the generator controller and the generator.

[0056] In the present application, the thermal management control device may further include a temperature sensor, and the temperature sensor is used to detect the actual temperature of the GCU and the generator.

[0057] Step S22, when the temperature sensor fails, controlling the first three-way valve, the second three-way valve, the first pipeline, the fifth pipeline and the fourth pipeline to be connected.

[0058] Specifically, when the temperature sensor fails, that is, when the temperature sensor cannot detect the actual temperature of the GCU and / or the generator, the cooling system will perform open-loop control, the first water inlet 121 of the first three-way valve 12 is connected to the second water outlet 123, the second water inlet 152 of the second three-way valve 15 is connected to the third water outlet 151, the first pipeline 101, the fifth pipeline 105 and the fourth pipeline 104 are connected, that is, the first three-way valve 12, the first pipeline 101, the fifth pipeline 105, the fourth pipeline 104 and the second three-way valve 15 are connected, the coolant first passes through the GCU and then passes through the generator, so as to realize series cooling of the GCU and the generator, and the priority of GCU thermal management is higher than that of the generator.

[0059] When the temperature sensor fails, the cooling system switches to open-loop control mode. In this mode, the system cannot monitor and adjust the actual temperature of the generator and GCU in real time. Therefore, the cooling system needs a reliable default strategy to prevent overheating to ensure that even in the worst case, the system will not be damaged due to excessive temperature and ensure the safe operation of the system.

[0060] In the generator set, the GCU is a key component that controls the operation of the generator. It needs to maintain a stable temperature under various working conditions to ensure the reliable operation of the generator. The GCU is a control unit and the generator is an execution unit. The thermal management priority of the GCU is higher than that of the generator, and the GCU has a lower power limit temperature than the generator. Therefore, when the temperature sensor fails, the coolant is first cooled by the GCU to ensure that the GCU can still be sufficiently cooled without real-time temperature feedback, thereby maintaining the stable operation of the generator. Once the GCU is sufficiently cooled, the coolant will then flow through the generator to cool the generator, ensuring that in the event of a temperature sensor failure, the key components GCU and the generator can receive the necessary cooling to prevent damage caused by excessive temperature.

[0061] Step S23, when the temperature sensor operates normally, the on / off of the pipeline system is controlled based on the actual temperature T1 of the generator detected by the temperature sensor, the actual temperature T2 of the generator controller and a preset thermal management control strategy.

[0062] In the present application, the above-mentioned thermal management control device is utilized, and when the temperature sensor cannot detect the temperature of the GCU and / or the generator, GCU priority cooling is adopted to ensure the safe operation of the cooling system. When the temperature sensor is operating normally, the actual temperature of the GCU and the generator detected by the temperature sensor and the preset thermal management control strategy are used to control the on and off of the pipeline system to achieve separate cooling of the GCU and the generator, and by adjusting the thermal management priority of the GCU and the generator, hierarchical cooling of the GCU and the generator is achieved, which helps to improve the working efficiency of the cooling system and reduce energy consumption.

[0063] Figure 3 The judgment flow chart of the thermal management control method provided in the embodiment of the present application is as follows: Figure 3 As shown, when T1 and / or T2 cannot be detected, GCU priority thermal management is performed.

[0064] In some embodiments, when T1≥T3>T2, T3 is a preset temperature threshold, and generator thermal management is performed, that is, the first water inlet 121 in the thermal management control device is controlled to be connected to the first water outlet 122, the second water inlet 152 is connected to the third water outlet 151, and the third pipe 103 and the fourth pipe 104 are connected, that is, the first three-way valve 12, the third pipe 103, the fourth pipe 104 and the second three-way valve 15 are connected. At this time, the coolant only passes through the generator to achieve separate cooling of the generator.

[0065] When T2≥T3>T1, GCU thermal management is performed, that is, the first water inlet 121 in the thermal management control device is controlled to be connected with the second water outlet 123, the third water inlet 153 is controlled to be connected with the third water outlet 151, and the first pipeline 101 and the second pipeline 102 are connected, that is, the first three-way valve 12, the first pipeline 101, the second pipeline 102 and the second three-way valve 15 are connected. At this time, the coolant only passes through the GCU to achieve separate cooling of the GCU.

[0066] It should be noted that when the generator is cooled alone, the coolant in the fifth pipe 105 does not flow, and the GCU cannot be cooled at this time; similarly, when the GCU is cooled alone, the coolant in the fifth pipe 105 does not flow, and the generator cannot be cooled at this time.

[0067] The present application controls the on-off of the pipeline system through the actual temperature of the GCU and the generator detected by the temperature sensor and the preset thermal management control strategy, thereby achieving separate cooling of the GCU and the generator, or stopping the operation of the electronic water pump, thereby reducing the energy consumption of the thermal management system of the entire vehicle. Since the energy consumption of the thermal management system of the entire vehicle is reduced, it is beneficial to increase the cruising range.

[0068] In some embodiments, when T1>T2≥T3, and ΔT1>ΔT2, T3 is a preset temperature threshold, ΔT1 is the temperature rise rate of the generator, ΔT2 is the temperature rise rate of the GCU, and generator priority thermal management is performed, that is, the first water inlet 121 in the thermal management control device is controlled to be connected to the first water outlet 122, the third water inlet 153 is connected to the third water outlet 151, the third pipeline 103, the fifth pipeline 105 and the second pipeline 102 are connected, that is, the first three-way valve 12, the third pipeline 103, the fifth pipeline 105, the second pipeline 102 and the second three-way valve 15 are connected, and the coolant first passes through the generator and then passes through the GCU, thereby forming a series cooling circuit between the GCU and the generator, and the generator is cooled preferentially.

[0069] When T2≥T1≥T3, or T1>T2≥T3 and ΔT2≥ΔT1, GCU priority thermal management is performed, that is, the first water inlet 121 in the thermal management control device is controlled to be connected with the second water outlet 123, the second water inlet 152 is controlled to be connected with the third water outlet 151, the first pipe 101, the fifth pipe 105 and the fourth pipe 104 are connected, that is, the first three-way valve 12, the first pipe 101, the fifth pipe 105, the fourth pipe 104 and the second three-way valve 15 are connected, and the coolant first passes through the GCU and then the generator, thereby forming a GCU and generator series cooling loop, and the GCU is cooled first. The present application adjusts the thermal management priority of the GCU and the generator according to the comparison of the actual temperature of the GCU and the generator detected by the temperature sensor and the preset temperature threshold, as well as the comparison of the temperature rise rate of the GCU and the generator, and realizes the hierarchical cooling of the GCU and the generator, which helps to improve the working efficiency of the thermal management system, and meets the requirements of the generator and GCU thermal management system quickly, in real time and reasonably according to the priority.

[0070] In some embodiments, when the GCU has a heating demand and T1>T2, generator priority thermal management is performed, that is, the first water inlet 121 in the thermal management control device is controlled to be connected to the first water outlet 122, the third water inlet 153 is connected to the third water outlet 151, the third pipeline 103, the fifth pipeline 105 and the second pipeline 102 are connected, that is, the first three-way valve 12, the third pipeline 103, the fifth pipeline 105, the second pipeline 102 and the second three-way valve 15 are connected, and the coolant first passes through the generator and then passes through the GCU, thereby forming a series cooling circuit between the GCU and the generator, and the generator is cooled preferentially.

[0071] In a low-temperature environment, when the GCU needs to be heated, the coolant first passes through the generator and then the GCU, using the waste heat from the generator to raise the temperature of the GCU, allowing the GCU to quickly reach the optimal operating temperature and the power generation system to quickly enter the optimal working state, reducing the operating time in the inefficient area and helping to shorten the charging time.

[0072] The thermal management control device and method provided in the present application can adjust the cooling pipelines of the thermal management system in parallel and series according to the actual temperature of the GCU and the generator and the preset temperature control strategy, and can also realize the intelligent control of modules requiring thermal management such as DC / DC, with strong compatibility. At the same time, even if the temperature sensor fails, the generator and GCU can be cooled to ensure that the function of the generator system is not affected, and the reliability is high.

[0073] An embodiment of the present application also provides a vehicle controller, including: a memory and a processor, the memory is used to store a computer program; the processor is used to run the computer program to implement the method provided by the embodiment shown in the present application.

[0074] An embodiment of the present application further provides a storage medium, the storage medium including a stored program, wherein when the program is running, the device where the storage medium is located is controlled to execute the method provided by the embodiment shown in the present application.
