Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a control method, computer device, and storage medium for an automotive cooling system. Background Technology

[0002] Vehicle-mounted equipment generates heat during operation, requiring cooling from the vehicle's cooling system to maintain optimal equipment performance and ensure vehicle safety. A typical vehicle has multiple onboard devices requiring cooling. Sharing a single cooling system (or a cooling circuit within the same system) simplifies system design, reduces system complexity, and enhances ease of use and maintenance. For example, in current electric vehicles, the motor, MCU (Microcontroller Unit), and DC-DC converter circuitry can share a single cooling system.

[0003] However, when multiple vehicle-mounted devices share a single cooling system, it is easy for only some of these devices to require cooling while others do not. In this situation, the cooling system needs to be operated to cool the devices that require cooling, but it also provides cooling to the devices that do not require cooling. This is unnecessary, resulting in unnecessary energy consumption and a reduced lifespan for the cooling system. Summary of the Invention

[0004] In view of the technical problems that arise from multiple vehicle devices sharing a single cooling system, such as unnecessary energy consumption and reduced service life of the cooling system, the present invention aims to provide a control method, computer device, and storage medium for an automotive cooling system.

[0014] Based on the efficiency curve, the coolant volume of the first pipeline is obtained; the coolant volume of the first pipeline is the coolant volume with the highest efficiency corresponding to the operating parameters of the first vehicle-mounted equipment.

[0015] Based on the pressure-flow diagram, the flow rate of the first water pump is obtained; the flow rate of the first water pump is the most efficient water pump flow rate corresponding to the operating parameters of the first vehicle-mounted equipment.

[0016] The operating time is determined based on the amount of coolant in the first pipeline and the flow rate of the first water pump.

[0017] Further, determining the running time based on the coolant volume in the first pipeline and the flow rate of the first water pump includes:

[0021] Furthermore, controlling the intermittent operation of the vehicle cooling system based on the runtime includes:

[0022] Determine the pause duration;

[0023] The vehicle cooling system is controlled to alternately operate and pause; wherein, the cumulative duration of continuous operation of the vehicle cooling system in each cycle is the operating duration, and the cumulative duration of continuous pause of the vehicle cooling system in each cycle is the pause duration.

[0024] Furthermore, determining the pause duration includes:

[0025] Set a work cycle; the work cycle is a fixed duration.

[0026] The pause duration is determined based on the difference between the work cycle and the runtime.

[0027] Furthermore, determining the pause duration includes:

[0028] Among the multiple on-board devices connected to the vehicle cooling system, a second on-board device is identified; the second on-board device is an on-board device that currently does not have a heat dissipation requirement.

[0029] Based on the efficiency curve, the coolant volume of the second pipeline is obtained; the coolant volume of the second pipeline is the coolant volume with the lowest efficiency corresponding to the operating parameters of the second vehicle-mounted equipment.

[0030] Based on the pressure-flow diagram, the flow rate of the second water pump is obtained; the flow rate of the second water pump is the lowest efficiency water pump flow rate corresponding to the operating parameters of the second vehicle-mounted equipment.

[0031] The pause duration is determined based on the coolant volume in the second pipeline and the flow rate of the second water pump.

[0040] The beneficial effects of the present invention are as follows: the control method of the automobile cooling system in the embodiment allows the automobile cooling system to run for only the time equivalent to the running time in a working cycle. Thus, when only a portion of the vehicle equipment is the vehicle equipment that needs to be cooled (the first vehicle equipment), the cooling demand of the vehicle equipment that needs to be cooled can be met with high efficiency. The intermittent operation of the automobile cooling system can reduce the actual running time of the automobile cooling system, thereby reducing the energy consumption of the automobile cooling system and reducing the loss of the cooling system's working life.

[0046] In this embodiment, refer to Figure 1 An automotive cooling system provides cooling for multiple onboard devices through a single cooling circuit; that is, multiple onboard devices share a single cooling circuit. The cooling system includes a cooling circuit, a water pump, a radiator, and coolant. The cooling circuit is connected to onboard devices such as the main drive motor, MCU, and DC-DC converter circuit (or the radiator installed on these devices), allowing heat generated by the onboard devices to be transferred to the coolant in the cooling circuit. When the automotive cooling system is running, the water pump drives the coolant to flow in the cooling circuit, thereby transferring the heat absorbed by the onboard devices to the radiator. The radiator then dissipates the heat through passive or active air cooling, thus cooling the onboard devices.

[0047] In some related technologies, water pumps only have two settings: stop and full speed. When only some onboard equipment has a cooling requirement, the cooling system will control the water pump to run at full speed, resulting in unnecessary energy consumption.

[0048] In this embodiment, refer to Figure 2 The control method for the automotive cooling system includes the following steps:

[0049] S1. Among the multiple on-board devices connected to the vehicle cooling system, determine the first on-board device;

[0050] S2. Determine the running time based on the operating parameters of the first on-board equipment;

[0051] S3. Control the intermittent operation of the vehicle's cooling system based on the operating time.

[0052] Steps S1-S3 can be executed by the onboard microprocessor.

[0053] Step S1 is the step of identifying the on-board devices with cooling needs from among the multiple on-board devices connected to the vehicle's cooling system. Specifically, when performing step S1, the following steps can be executed:

[0054] S101. Detect the operating temperature of each vehicle-mounted device;

[0055] S102. When the operating temperature of any vehicle-mounted device reaches the corresponding temperature threshold of the vehicle-mounted device, the vehicle-mounted device is identified as the first vehicle-mounted device.

[0056] In step S101, the operating temperature of each vehicle-mounted device is measured using a temperature sensor shared by all the devices, or by temperature sensors independently installed on each device. In step S102, the operating temperature of each device is compared with a corresponding temperature threshold. For example, the operating temperature of the main drive motor is compared with its corresponding temperature threshold. If the operating temperature of the main drive motor is higher than its corresponding temperature threshold, then the main drive motor is a device requiring cooling, i.e., the first device; otherwise, the main drive motor is a device without cooling requirements, i.e., the second device.

[0057] Similarly, the operating temperature of the MCU is compared with its corresponding temperature threshold. If the MCU's operating temperature is higher than its corresponding temperature threshold, then the MCU is the first vehicle-mounted device; otherwise, the MCU is the second vehicle-mounted device as it does not require cooling. The operating temperature of the DC-DC converter circuit is also compared with its corresponding temperature threshold. If the DC-DC converter circuit's operating temperature is higher than its corresponding temperature threshold, then the DC-DC converter circuit is the first vehicle-mounted device; otherwise, the DC-DC converter circuit is the second vehicle-mounted device as it does not require cooling.

[0058] In this embodiment, when executing step S1, parameters other than temperature can also be used to determine whether a vehicle-mounted device belongs to the first vehicle-mounted device or the second vehicle-mounted device. For example, for the main drive motor, a vehicle-mounted device, the wheel speed of the car can be detected. When the wheel speed is lower than the speed threshold, it can be determined that the car is stationary, that is, the main drive motor is not working. The main drive motor does not generate heat, thus determining that the main drive motor is a vehicle-mounted device that does not require cooling, i.e., the second vehicle-mounted device.

[0059] Since only a small number of first-class vehicle-mounted devices exist among multiple vehicle-mounted devices, and the rest are second-class vehicle-mounted devices, the waste caused by the full-speed operation of the vehicle cooling system (including the water pump) is quite significant. This situation is a typical application scenario of steps S1-S3. Therefore, in this embodiment, taking the vehicle-mounted devices including the main drive motor, MCU, and DC-DC conversion circuit, where only the DC-DC conversion circuit belongs to the first-class vehicle-mounted device (vehicle-mounted device with cooling requirements), and the main drive motor and MCU both belong to the second-class vehicle-mounted devices (vehicle-mounted devices without cooling requirements) as an example, the steps in the control method of the vehicle cooling system are explained.

[0060] In this embodiment, when performing step S2, which is to determine the running time based on the operating parameters of the first vehicle-mounted device, the following steps can be performed:

[0061] S201. Obtain the efficiency curve and pressure-flow diagram of the cooling system;

[0062] S202. Based on the efficiency curve, the coolant volume of the first pipeline is obtained;

[0063] S203. Based on the pressure-flow diagram, the flow rate of the first water pump is obtained;

[0064] S204. Determine the running time based on the coolant volume in the first pipeline and the flow rate of the first water pump.

[0065] In step S201, the obtained efficiency curve of the cooling system is shown in the figure below. Figure 3 As shown, the obtained pressure-flow diagram of the cooling system is as follows: Figure 4 As shown.

[0066] Reference Figure 3 The efficiency curve graph shows the relationship between the operating efficiency of the cooling system (including the water pump) and the coolant flow rate, where the vertical axis represents the water pump efficiency and the horizontal axis represents the coolant flow rate. (Refer to...) Figure 4 The pressure-flow diagram shows the relationship between the pressure of the cooling system (including the water pump) and the flow rate of the coolant, with the vertical axis representing the water pump pressure and the horizontal axis representing the coolant flow rate. Figure 3 and Figure 4The multiple curves within correspond to different operating parameters of the first vehicle-mounted device. That is, based on a set of determined operating parameters of the first vehicle-mounted device, they can be respectively... Figure 3 and Figure 4 Determine a curve in the middle, and then according to Figure 3 The curve in the figure determines the corresponding relationship between the pump's operating efficiency and the coolant flow rate. Figure 4 The curve in the figure determines the relationship between the water pump pressure and the coolant flow rate.

[0067] In step S202, refer to Figure 3 Each curve in the efficiency graph has a maximum efficiency value. When determining a... Figure 3 In the case of the curve, the point with the highest efficiency can be determined on this curve, thereby determining the corresponding pipeline coolant volume (i.e., the corresponding horizontal axis coordinate), and the pipeline coolant volume corresponding to this point is determined as the first pipeline coolant volume.

[0068] In step S203, refer to Figure 4 Each curve in the pressure-flow diagram has a maximum efficiency. When determining a... Figure 4 In the case of the curve, we can determine the point with the highest efficiency on this curve, thereby determining the water pump flow rate corresponding to this point (i.e., the corresponding horizontal axis coordinate), and determining the pipeline coolant flow rate corresponding to this point as the first water pump flow rate.

[0069] In step S204, according to the formula

[0070]

[0071] Perform the calculation to obtain the runtime.

[0072] In this embodiment, the principle of executing steps S201-S204 is as follows: the first pipeline coolant volume obtained in step S202 can represent the pipeline coolant volume at which the highest efficiency is achieved when the determined first vehicle-mounted device needs to be cooled by the operation of the vehicle cooling system (i.e., the amount of coolant that needs to be transported in the cooling circuit to cool the first vehicle-mounted device); the first water pump flow rate obtained in step S203 can represent the water pump flow rate at which the highest efficiency is achieved when the determined first vehicle-mounted device needs to be cooled by the operation of the vehicle cooling system (i.e., the amount of coolant pumped by the water pump per unit time); through the formula in step S204, the time required for the water pump to pump the first pipeline coolant volume at the first water pump flow rate in one working cycle can be calculated. Therefore, by controlling the running time obtained from executing steps S201-S204 to control the vehicle cooling system (including the water pump), the working efficiency of the vehicle cooling system can be equal to or close to the maximum efficiency.

[0073] In this embodiment, when performing step S3, which is to control the intermittent operation of the vehicle cooling system based on the runtime, the following steps can be specifically performed:

[0074] S301. Determine the pause duration;

[0075] S302. Control the vehicle cooling system to alternately run and pause; wherein, the cumulative duration of continuous operation of the vehicle cooling system in each cycle is the running duration, and the cumulative duration of continuous pause of the vehicle cooling system in each cycle is the pause duration.

[0076] In step S302, the runtime obtained from steps S201-S204 is used as the cumulative duration of continuous operation of the vehicle cooling system (including the water pump) in each cycle, and the pause duration set in step S301 is used as the cumulative duration of pause of the vehicle cooling system (including the water pump) in each cycle. For example, refer to... Figure 5 A work cycle can be divided into the first part as the running time and the remaining part as the pause time. Within a work cycle, the running time and the pause time do not have to be continuous. It is sufficient that the cumulative running time of the car cooling system (including the water pump) within a work cycle reaches the running time and the cumulative pause time reaches the pause time.

[0077] In this embodiment, by executing steps S1-S3, the vehicle cooling system can only run for a time equivalent to the operating time in a working cycle. Thus, when only a portion of the vehicle equipment needs to be cooled (the first vehicle equipment), the cooling requirements of the vehicle equipment that needs to be cooled can be met with high efficiency. The intermittent operation of the vehicle cooling system can reduce the actual operating time of the vehicle cooling system, thereby reducing the energy consumption of the vehicle cooling system and reducing the loss of the cooling system's service life.

[0078] In this embodiment, when performing step S301, which is the step of determining the pause duration, the following steps can be performed:

[0079] S30101A. Set the work cycle;

[0080] S30102A. Determine the pause duration based on the difference between the work cycle and the runtime.

[0081] Steps S30101A-S30102A are the first execution method of step S301.

[0082] In step S30101A, a fixed-duration work cycle is set, and then step S30102A is executed, subtracting the running time obtained from step S2 from the work cycle, and the difference is the pause duration.

[0083] By executing steps S30101A-S30102A, the pause duration can be set with simple calculations. The sum of the running duration and the pause duration, i.e., the work cycle, is a fixed value. This means that each start-stop cycle completed by the automotive cooling system has a fixed duration, thus facilitating other control processes of the automotive cooling system.

[0084] In this embodiment, when performing step S301, which is the step of determining the pause duration, the following steps can be performed:

[0085] S30101B. Among the multiple on-board devices connected to the vehicle cooling system, a second on-board device is identified; the second on-board device is an on-board device that currently does not have a cooling requirement;

[0086] S30102B. Based on the efficiency curve, the coolant volume of the second pipeline can be obtained.

[0087] S30103B. Based on the pressure-flow diagram, the flow rate of the second water pump can be obtained;

[0088] S30104B. Determine the pause duration based on the coolant volume in the second pipeline and the flow rate of the second water pump.

[0089] Steps S30101B-S30104B are the second execution method of step S301.

[0090] In step S30101B, after the first vehicle-mounted device among multiple vehicle-mounted devices is determined in step S1, the second vehicle-mounted device is naturally determined.

[0091] When performing step S30102B, refer to the principle of step S202. Figure 3 In the efficiency graph, each curve has a minimum efficiency value. When determining a... Figure 3 In the case of the curve, we can determine the point of lowest efficiency on this curve, thereby determining the corresponding pipeline coolant volume (i.e., the corresponding horizontal axis coordinate), and determine the pipeline coolant volume corresponding to this point as the second pipeline coolant volume.

[0092] When performing step S30103B, refer to the principle of step S203. Figure 4 In the pressure-flow diagram, each curve has a minimum efficiency. When determining a... Figure 4 In the case of the curve, we can determine the point of lowest efficiency on this curve, thereby determining the water pump flow rate corresponding to this point (i.e., the corresponding horizontal axis coordinate), and determine the pipeline coolant flow rate corresponding to this point as the second water pump flow rate.

[0093] When performing step S30104B, referring to the principle of step S204, the formula can be used.

[0094]

[0095] Perform the calculation to obtain the pause duration.

[0096] In this embodiment, the principle of executing steps S30101B-S30104B is as follows: the second pipeline coolant volume obtained in step S30102B can represent the pipeline coolant volume at which the automotive cooling system achieves minimum efficiency when assuming the need to cool a specific second vehicle-mounted device (i.e., the amount of coolant that needs to be transported in the cooling circuit to cool the second vehicle-mounted device); the second water pump flow rate obtained in step S30103B can represent the water pump flow rate at which the automotive cooling system achieves minimum efficiency when assuming the need to cool a specific second vehicle-mounted device (i.e., the amount of coolant pumped by the water pump per unit time); through the formula in step S30104B, the flow rate of the water pump in one working cycle can be calculated at the second water pump flow rate. The time required for the pump to deliver coolant to the second pipeline is considered. Therefore, assuming that the vehicle cooling system (including the water pump) cools the second on-board equipment for the same duration as the pause obtained in step S30104B, the vehicle cooling system will reach or approach its minimum operating efficiency. Correspondingly, since the vehicle cooling system (including the water pump) does not cool any on-board equipment during the pause obtained in step S30104B when actually executing steps S1-S3, low operating efficiency can be avoided. This also allows the vehicle cooling system to remain in a paused state for a sufficient amount of time, making the effect of reducing energy consumption and minimizing the loss of the cooling system's service life achieved by the vehicle cooling system control method in this embodiment more significant.

[0097] The above formula This only considers the case of a single second vehicle-mounted device. When multiple second vehicle-mounted devices exist, the formula for calculating the pause duration in step S30104B can be improved as follows: or

[0098] formula The calculated pause duration is equivalent to the sum of the pause durations obtained by executing steps S30101B-S30104B on each of the second vehicle-mounted devices. When the vehicle cooling system is paused according to the pause duration calculated by this formula, the low efficiency faced by "assuming cooling for each second vehicle-mounted device" can be avoided when there are multiple second vehicle-mounted devices, making the efficiency improvement effect of the vehicle cooling system control method in this embodiment more significant.

[0099] formula The calculated pause duration is equivalent to the maximum pause duration obtained by executing steps S30101B-S30104B on each of the second vehicle-mounted devices. The pause duration calculated by this formula is greater than that calculated by formula... The calculated pause duration is short. When the vehicle cooling system is paused according to the pause duration calculated by this formula, the pause duration can be reduced, which helps to avoid an excessively long working cycle of the vehicle cooling system and facilitates aspects such as the control programming of the vehicle cooling system.

[0100] A computer program that executes the control method of the automobile cooling system in this embodiment can be written into a computer device or storage medium. When the computer program is read out and run, the control method of the automobile cooling system in this embodiment is executed, thereby achieving the same technical effect as the control method of the automobile cooling system in the embodiment.
