Description

Technical Field

[0001] This application relates to the field of temperature control technology, and in particular to an on-board liquid cooling system, a temperature compensation method, a device, an equipment, and a storage medium. Background Technology

[0002] Automotive electronic devices need to operate within a wide temperature range, such as -40°C to 50°C. This creates a need for automotive electronic devices to start in low-temperature environments. However, automotive electronic devices are prone to malfunctions when starting in low temperatures.

[0003] Specifically, in low-temperature environments, the components in vehicle electronic devices perform poorly and are prone to malfunctions during startup. For example, vehicle electrical equipment is more likely to fail to start in low-temperature environments. Moreover, during startup, the heat generated by the high-power chips in vehicle electronic devices increases sharply, rapidly heating the surrounding air. When this hot air comes into contact with the slower-heating components in the vehicle electronic devices, condensation is easily generated. This condensation can cause circuit corrosion and ion migration in the vehicle electronic devices, ultimately leading to electrical short circuits or even permanent damage. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, 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.

[0021] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0022] This application provides an embodiment of an on-board liquid cooling system. For example... Figure 1 The diagram shown is a structural diagram of an on-board liquid cooling system according to an embodiment of this application.

[0023] The vehicle-mounted liquid cooling system includes at least: a first heating element 2, a liquid supply pump 3, a second heating element 4, a liquid supply valve 5, and a controller (not shown in the figure), all mounted on the liquid supply line 1. This vehicle-mounted liquid cooling system is used to supply heated or cooled coolant to the vehicle-mounted electronic equipment 6. The coolant may be a 67% ethylene glycol solution.

[0024] The first heating component 2 is installed on the liquid supply pipeline 1 and is within the preset range of the liquid supply pump 3.

[0025] The second heating component 4 is installed on the liquid supply line 1 and is within the preset range of the liquid supply valve 5.

[0026] A controller is used to control the first heating component 2 and / or the second heating component 4 to heat the coolant in the liquid supply pipeline 1.

[0027] With this configuration, when the controller controls the first heating component 2 to heat, it can heat the coolant in the vicinity of the liquid supply pump 3, thus enabling the liquid supply pump 3 to start normally. After the liquid supply pump starts, the coolant will circulate in the liquid supply pipeline 1. At this time, the controller controls the first heating component 2 and the second heating component 4 to heat together, so that the coolant in the liquid supply pipeline 1 can be heated evenly.

[0028] The following describes the specific structure of the vehicle-mounted liquid cooling system. Figure 2 This is a detailed structural diagram of an on-board liquid cooling system according to an embodiment of this application.

[0029] The first heating assembly 2 includes: a first electromagnetic heater 7 and a second electromagnetic heater 8; wherein, the first electromagnetic heater 7 is disposed on the liquid supply pipeline 1 on the water inlet side of the liquid supply pump 3; the second electromagnetic heater 8 is disposed on the liquid supply pipeline 1 on the water outlet side of the liquid supply pump 3; the second heating assembly 4 includes: a third electromagnetic heater 9 and a fourth electromagnetic heater 10; wherein, the third electromagnetic heater 9 and the fourth electromagnetic heater 10 are both disposed on the liquid supply pipeline 1 on the water inlet side of the liquid supply valve 5.

[0030] Furthermore, the first electromagnetic heater 7 and the second electromagnetic heater 8 have the same specifications. The third electromagnetic heater 9 and the fourth electromagnetic heater 10 have the same specifications. Of course, the first electromagnetic heater 7, the second electromagnetic heater 8, the third electromagnetic heater 9, and the fourth electromagnetic heater 10 can all have the same specifications. For example, the first electromagnetic heater 7, the second electromagnetic heater 8, the third electromagnetic heater 9, and the fourth electromagnetic heater 10 can all be 300W electromagnetic heaters.

[0031] Furthermore, the controller can control the first electromagnetic heater 7 and the second electromagnetic heater 8 to turn on or off simultaneously. If one of the electromagnetic heaters, the first electromagnetic heater 7 and the second electromagnetic heater 8, fails, the malfunctioning electromagnetic heater can be controlled independently by the controller.

[0032] Furthermore, the controller can control the third electromagnetic heater 9 and the fourth electromagnetic heater 10 to turn on or off simultaneously. If one of the electromagnetic heaters, the third electromagnetic heater 9 and the fourth electromagnetic heater 10, fails, the malfunctioning electromagnetic heater can be controlled independently by the controller.

[0033] Thus, the vehicle-mounted liquid cooling system includes: a return valve 11, a supply pump 3, a first electromagnetic heater 7, a second electromagnetic heater 8, a check valve 12, a heat exchanger 13, a refrigeration system 14, a filter 15, a third electromagnetic heater 9, a fourth electromagnetic heater 10, a supply valve 5, and a controller (not shown in the figure).

[0034] The return valve 11, the supply pump 3, the first heating assembly 2 (first electromagnetic heater 7 and second electromagnetic heater 8), the check valve 12, the heat exchanger 13, the filter 15, the second heating assembly 4 (third electromagnetic heater 9 and fourth electromagnetic heater 10), and the supply valve 5 are all installed on the supply pipeline 1. The supply port 16 and the return port 17 of the supply pipeline 1 are both connected to the vehicle electronic equipment 6. The refrigeration system 14 is coupled to the heat exchanger 13. The coolant circulates in the supply pipeline 1, enters the vehicle electronic equipment 6 from the supply port 16, and flows back to the supply pipeline 1 from the return port 17.

[0035] The return valve 11 is used to control the return flow of coolant into the vehicle electronic equipment 6 under the control of the controller.

[0036] The coolant supply pump 3 is used to drive the coolant to circulate throughout the coolant supply line 1 under the control of the controller.

[0037] The first electromagnetic heater 7 and the second electromagnetic heater 8 are used to simultaneously heat the coolant in the liquid supply line 1 under the control of the controller.

[0038] The one-way valve 12 is used to prevent coolant backflow and ensure that the coolant circulates in a single direction.

[0039] The heat exchanger 13 is used in conjunction with the refrigeration system 14 under the control of the controller to cool the coolant in the liquid supply line 1.

[0040] Filter 15 is used to filter impurities and particulate matter in the coolant, preventing downstream supply pump 3, valves and heat exchanger 13 from clogging or wear.

[0041] The third electromagnetic heater 9 and the fourth electromagnetic heater 10 are used to simultaneously heat the coolant in the liquid supply line 1 under the control of the controller.

[0042] The coolant supply valve 5 is used to control the flow of coolant to the vehicle electronic equipment 6 under the control of the controller.

[0043] Based on the aforementioned vehicle-mounted liquid cooling system, this application provides a temperature compensation method. The executing entity in this application embodiment can be the aforementioned controller. For example... Figure 3 The diagram shown is a flowchart of a temperature compensation method according to an embodiment of this application.

[0044] Step S310: Before turning on the vehicle electronic equipment, monitor the liquid supply temperature of the liquid cooling system in real time.

[0045] The types of in-vehicle electronic equipment include, but are not limited to: in-vehicle radar.

[0046] The supply temperature refers to the temperature of the coolant in the supply line. Furthermore, a temperature sensor can be installed between the supply pump and the return valve to monitor the supply temperature of the coolant in the supply line.

[0047] Specifically, the liquid supply temperature can be monitored in real time after receiving a power-on request from the vehicle-mounted electronic device. The power-on request is used to request the activation of the vehicle-mounted electronic device. This activation request can originate from the vehicle control device corresponding to the vehicle-mounted electronic device, or from the user terminal used to control the vehicle-mounted electronic device.

[0048] Furthermore, real-time monitoring of the liquid supply temperature means monitoring the liquid supply temperature once every preset monitoring time period. Therefore, the temperature replenishment method of this application embodiment is executed once every preset monitoring time period.

[0049] Step S320: Determine whether the real-time monitored liquid supply temperature is lower than the operating temperature threshold corresponding to the vehicle electronic device; if yes, proceed to step S330; if no, proceed to step S350.

[0050] The operating temperature threshold for automotive electronic devices refers to the temperature required for normal startup and operation. Furthermore, the operating temperature threshold for automotive electronic devices can also be the minimum temperature required for normal startup and operation.

[0051] Step S330: When the real-time monitored liquid supply temperature is lower than the operating temperature threshold corresponding to the vehicle electronic device, control the first heating component to heat the liquid supply pipeline.

[0052] The first heating component refers to the heating component installed on the liquid supply pipeline and located within the preset range of the liquid supply pump.

[0053] In this embodiment of the application, if the currently monitored coolant supply temperature is lower than the operating temperature threshold corresponding to the vehicle electronic equipment, it indicates that the current coolant temperature is insufficient. At this time, local heating can be activated to increase the temperature of the key location of the coolant supply pump, reduce the viscosity of the coolant at this key location, and avoid overload and damage caused by the coolant being too viscous after the coolant supply pump is started.

[0054] Step S340: After the first heating component has been working continuously for a preset time period, start the liquid supply pump and control the first heating component and the second heating component to simultaneously heat the liquid supply pipeline, then proceed to step S320.

[0055] The preset time period refers to the heating duration of the first heating component, which is used to control the local coolant at the liquid supply pump position to be sufficiently heated to start coolant circulation.

[0056] The coolant supply pump is used to drive the coolant to circulate in the supply line. The coolant supply pump can operate at a flow rate of 42 m³ / h.

[0057] The second heating component refers to the heating component installed on the liquid supply pipeline and located within the preset range of the liquid supply valve.

[0058] In this embodiment, after local heating, the coolant supply pump is started to drive the coolant circulation, so that the heated coolant flows to other parts. At the same time, the second heating component is turned on, so that the first heating component and the second heating component work together to continuously heat the coolant in circulation, thereby efficiently transferring heat to the entire coolant supply pipeline and vehicle electronic equipment, achieving rapid and uniform overall preheating.

[0059] Step S350: When the real-time monitored liquid supply temperature is greater than or equal to the operating temperature threshold corresponding to the vehicle electronic device, control the vehicle electronic device to turn on and turn off the first heating component and the second heating component.

[0060] If the current monitored liquid supply temperature is greater than or equal to the operating temperature threshold of the vehicle electronic equipment, it means that the current liquid supply temperature has met the temperature required for the normal operation of the vehicle electronic equipment. At this time, it means that the preheating target has been achieved, the vehicle electronic equipment can be started, and the first heating component and the second heating component can be turned off to save energy consumption.

[0061] Furthermore, a power-on request corresponding to the vehicle electronic device can be sent to the vehicle electronic device to turn it on and turn off the first heating component and the second heating component.

[0062] In this embodiment, the liquid supply temperature of the liquid cooling system can be monitored in real time before the vehicle electronic device is turned on; it can be determined whether the monitored liquid supply temperature is lower than the operating temperature threshold corresponding to the vehicle electronic device; when the monitored liquid supply temperature is lower than the operating temperature threshold corresponding to the vehicle electronic device, the first heating component is controlled to heat the liquid supply pipeline; after the first heating component has been working continuously for a preset time period, the liquid supply pump is started and the first heating component and the second heating component are controlled to heat the liquid supply pipeline simultaneously; when the monitored liquid supply temperature is greater than or equal to the operating temperature threshold corresponding to the vehicle electronic device, the vehicle electronic device is controlled to turn on and off the first heating component and the second heating component. In this embodiment, before turning on the vehicle electronic equipment, the coolant supply temperature is monitored. When the coolant supply temperature is lower than the operating temperature threshold of the vehicle electronic equipment, the coolant in the supply pipeline is heated in stages. First, the coolant at the supply pump location is locally heated to enable the supply pump to start smoothly. After the supply pump starts, the coolant at the supply pump location and the supply valve location are heated simultaneously, so that the circulating coolant can quickly and evenly reach the operating temperature threshold of the vehicle electronic equipment. This allows the vehicle electronic equipment to start within its operating temperature range, thereby solving the problem that vehicle electronic equipment is prone to failure when starting at low temperatures.

[0063] To make the embodiments of this application easier to understand, the temperature compensation method of the embodiments of this application will be further described below.

[0064] In this embodiment of the application, after receiving the power-on request corresponding to the vehicle electronic device, the liquid supply temperature can be monitored in real time, and it can be determined whether the monitored liquid supply temperature is less than the operating temperature threshold corresponding to the vehicle electronic device.

[0065] Specifically, after the vehicle electronic device is powered on, the power-on request corresponding to the vehicle electronic device can be received by interception. After receiving the power-on request, the vehicle electronic device is not turned on temporarily. Instead, the liquid supply temperature of the liquid supply line is monitored in real time to see if it is lower than the operating temperature threshold of the vehicle electronic device.

[0066] The operating temperature range for automotive electronic devices can be from -20℃ to 5℃, therefore, the operating temperature threshold for automotive electronic devices can be -20℃. Of course, the operating temperature threshold for automotive electronic devices can be set according to requirements.

[0067] In this embodiment, when the real-time monitored supply temperature is lower than the operating temperature threshold corresponding to the vehicle electronic device, the first heating component is controlled to heat the supply pipeline so that the coolant near the supply pump in the supply pipeline is heated; after the first heating component has been working continuously for a preset time period, the supply pump is started and the first heating component and the second heating component are controlled to heat the supply pipeline so that the coolant circulating in the supply pipeline is heated evenly.

[0068] Specifically, the embodiments of this application involve heating the coolant in two stages. The first heating stage is localized heating based on the first heating component. The second heating stage is uniform heating based on both the first and second heating components. The two heating stages are described in detail below.

[0069] First heating stage: such as Figure 4 The diagram shown is a flowchart of the first heating stage according to an embodiment of this application.

[0070] Step S410: When the real-time monitored liquid supply temperature is lower than the operating temperature threshold corresponding to the vehicle electronic device, determine the liquid supply temperature difference between the real-time monitored liquid supply temperature and the operating temperature threshold corresponding to the vehicle electronic device.

[0071] The fluid supply temperature difference refers to the temperature difference between the real-time monitored fluid supply temperature and the corresponding operating temperature threshold of the vehicle electronic equipment. For example: Temperature difference = T1 - Tout; where T1 is the corresponding operating temperature threshold of the vehicle electronic equipment; and Tout is the real-time monitored fluid supply temperature.

[0072] Step S420: Determine whether the liquid supply temperature difference is greater than a preset temperature difference threshold; if yes, proceed to step S430; if no, proceed to step S440.

[0073] Temperature thresholds are used to distinguish critical values ​​for different heating modes. These thresholds can be empirical values ​​or values ​​obtained experimentally. For example, a temperature threshold of 20℃.

[0074] Step S430: When the supply liquid temperature difference is greater than a preset temperature difference threshold, the first electromagnetic heater and the second electromagnetic heater in the first heating assembly are started at full power during the time period.

[0075] Full-power start-up means that both the first and second electromagnetic heaters operate at their maximum rated power (full power).

[0076] If the supply temperature difference is greater than the temperature difference threshold, it indicates that the ambient temperature is too low and the coolant needs to be heated up quickly to avoid cold surge current in the vehicle's electronic equipment. In this case, the electromagnetic heaters in the first heating component will be started at full power first.

[0077] Furthermore, both the first and second electromagnetic heaters can be controlled to reach their maximum rated power within a preset start-up time period. The duration of this start-up time period can be set according to requirements. For example, the start-up time period can be 1 minute, meaning that both the first and second electromagnetic heaters can be controlled to soft-start to their maximum rated power within 1 minute, and then the liquid supply pump can be turned on.

[0078] Step S440: If the supply liquid temperature difference is less than or equal to the temperature difference threshold, the first electromagnetic heater and the second electromagnetic heater in the first heating assembly are started with a preset partial power during the time period.

[0079] Starting at a preset partial power means that both the first and second electromagnetic heaters operate at a portion of their maximum rated power. Specifically, the first and second electromagnetic heaters use the same power. The magnitude of this partial power can be determined according to requirements. For example, if the supply liquid temperature difference is less than or equal to the temperature difference threshold, during the specified time period, both the first and second electromagnetic heaters in the first heating assembly will start at half power; that is, both the first and second electromagnetic heaters will operate at half of their maximum rated power.

[0080] If the liquid supply temperature difference is less than or equal to the temperature difference threshold, it indicates that the ambient temperature is low. The first and second electromagnetic heaters can be started at half power to avoid wasting electrical energy.

[0081] Furthermore, both the first and second electromagnetic heaters can be controlled to reach half of their maximum rated power within a preset start-up time period. For example, the start-up time period can be 1 minute, meaning that both the first and second electromagnetic heaters can be controlled to soft-start to half of their maximum rated power within 1 minute, and then the liquid supply pump can be turned on.

[0082] In this embodiment, when controlling the first electromagnetic heater and the second electromagnetic heater, PWM (Pulse Width Modulation) can be used to control the power of the first electromagnetic heater and the second electromagnetic heater respectively. This is because power is equal to the product of current and voltage; given a constant voltage, the power can be adjusted by adjusting the current.

[0083] This application embodiment calculates the liquid supply temperature difference in real time and compares it with a preset temperature difference threshold. It can dynamically select between full-power heating mode and half-power heating mode, thus balancing speed and economy in the low-temperature preheating process. When the temperature difference is large, it preheats at full power to ensure quick readiness, and when the temperature difference is small, it operates gently and energy-savingly. Ultimately, it ensures that the vehicle's electronic equipment can start reliably and quickly, while optimizing the utilization of the vehicle's energy.

[0084] Second heating stage: such as Figure 5 The diagram shown is a flowchart of the second heating stage according to an embodiment of this application.

[0085] Step S510: After starting the liquid supply pump, the coolant temperature rise power is determined in real time based on the real-time monitored liquid supply temperature and the corresponding operating temperature threshold of the vehicle electronic equipment.

[0086] Coolant temperature rise power refers to the power required to compensate for the temperature difference between the real-time monitored supply coolant temperature and the corresponding operating temperature threshold of the on-board electronic equipment. In other words, it is the power required to compensate for this temperature difference.

[0087] For example, the power consumption for coolant temperature rise can be calculated using the following formula: P = C × ΔT1; △T1=T1-Tout; Where P is the coolant temperature rise power, C is the specific heat capacity of the coolant; T1 is the operating temperature threshold corresponding to the vehicle electronic equipment; and Tout is the real-time monitored supply temperature.

[0088] Step S520: Determine the remaining required heating power based on the real-time determined cooling liquid temperature rise power and the heating power corresponding to the first electromagnetic heater and the second electromagnetic heater in the first heating assembly.

[0089] The remaining heating power requirement refers to the additional power required to reach the operating temperature threshold of the on-board electronic equipment, after deducting the heating power corresponding to the first and second electromagnetic heaters respectively. Further, based on the heating power (maximum rated power or half of the maximum rated power) of each activated electromagnetic heater, the sum of the power values ​​of each activated electromagnetic heater is calculated; the remaining heating power requirement is determined by subtracting this sum of power values ​​from the coolant temperature rise power.

[0090] Step S530: Determine whether the remaining heating power demand is greater than the preset safe power threshold; if yes, proceed to step S540; if no, proceed to step S550.

[0091] The safe power threshold refers to the maximum allowable power of a liquid cooling system. Setting a safe power threshold is to protect the safety of heat-resistant materials in the liquid cooling system.

[0092] Step S540: If the remaining required heating power is greater than the preset safe power threshold, start the third and fourth electromagnetic heaters in the second heating assembly, and control the sum of the power of the third and fourth electromagnetic heaters in the second heating assembly to the safe power threshold, and then execute step S560.

[0093] The remaining heating power requirement is greater than the safe power threshold, meaning that more remaining heating power is needed to reach the operating temperature threshold corresponding to the vehicle electronic equipment. While the current remaining heating power requirement exceeds the safe power threshold, the liquid cooling system needs to keep its power below the safe power threshold. Therefore, the sum of the power of the third and fourth electromagnetic heaters can be controlled to the safe power threshold. For example, the safe power threshold can be evenly distributed between the third and fourth electromagnetic heaters; in other words, the power of each heater can be adjusted to half of the safe power threshold.

[0094] Step S550: If the remaining heating power demand is less than or equal to a preset safe power threshold, start the third and fourth electromagnetic heaters in the second heating assembly, and control the sum of the power of the third and fourth electromagnetic heaters in the second heating assembly to the remaining heating power demand, and then execute step S560.

[0095] If the remaining heating power demand is greater than the safe power threshold, it means that more remaining heating power is needed to reach the operating temperature threshold corresponding to the vehicle electronic equipment. Since this remaining heating power demand is not greater than the safe power threshold, the sum of the power of the third and fourth electromagnetic heaters can be controlled to be the remaining heating power demand. For example, the remaining heating power demand can be evenly distributed between the third and fourth electromagnetic heaters; in other words, the power of each of the third and fourth electromagnetic heaters can be adjusted to half of the remaining heating power demand.

[0096] Step S560: After the first heating component and the second heating component are turned on, control the power and value of the first electromagnetic heater, the second electromagnetic heater, the third electromagnetic heater and the fourth electromagnetic heater to the currently determined cooling liquid temperature rise power.

[0097] In order to achieve uniform heating of the coolant in the supply line, the coolant temperature rise power can be evenly distributed to the first electromagnetic heater, the second electromagnetic heater, the third electromagnetic heater and the fourth electromagnetic heater. In other words, the power of the first electromagnetic heater, the second electromagnetic heater, the third electromagnetic heater and the fourth electromagnetic heater can be adjusted to one-quarter of the coolant temperature rise power.

[0098] This application embodiment converts the temperature difference into real-time temperature rise power demand and coordinates the power output of the two sets of heating components under different safety requirements, ultimately achieving precise control of the total system power. Thus, while ensuring that the total power does not exceed the safe power threshold, it maximizes the optimization of preheating speed and heating efficiency, achieving a balance between safety and responsiveness.

[0099] In this embodiment, after both the first heating component and the second heating component are turned on, the coolant temperature rise power can be determined in real time based on the real-time monitored supply temperature and the operating temperature threshold corresponding to the vehicle electronic device; if the currently determined coolant temperature rise power is less than the preset temperature rise power threshold, the first electromagnetic heater and the second electromagnetic heater in the first heating component are turned off; and the power and value of the third electromagnetic heater and the fourth electromagnetic heater in the second heating component are controlled to be the currently determined coolant temperature rise power.

[0100] The temperature rise power threshold refers to a preset intermediate temperature rise power when starting up automotive electronic devices in a low-temperature environment. This temperature rise power threshold can be used to optimize the number of electromagnetic heaters. Here, "low-temperature environment" refers to whether the real-time monitored fluid supply temperature is lower than the corresponding operating temperature threshold of the automotive electronic device. Furthermore, this temperature rise power threshold can be a preset value, or it can be queried based on the initially monitored fluid supply temperature.

[0101] If the coolant temperature rise power is less than the temperature rise power threshold, it indicates that the coolant temperature rise power is already low, and the electromagnetic heaters alone are sufficient to maintain the coolant temperature rise. In this case, some electromagnetic heaters can be turned off to gently heat the coolant and avoid temperature overshoot. Specifically, the electromagnetic heaters in the first heating assembly are turned off first because the coolant supply pump also generates heat during operation.

[0102] If the coolant temperature rise power is greater than or equal to the temperature rise power threshold, it means that the coolant temperature rise power is still relatively large and the coolant needs to be heated quickly. In this case, it is necessary to keep both the first heating component and the second heating component in a heating state.

[0103] In this embodiment of the application, when the real-time monitored liquid supply temperature is greater than or equal to the operating temperature threshold corresponding to the vehicle electronic device, the vehicle electronic device is controlled to turn on and off the first heating component and the second heating component.

[0104] If the liquid supply temperature is greater than or equal to the operating temperature threshold corresponding to the vehicle electronic device, it indicates that the preheating stage of the liquid cooling system has been completed and the liquid cooling system has provided a suitable operating temperature for the vehicle electronic device. At this time, a power-on request can be sent to the vehicle electronic device to turn it on. In order to reduce energy consumption, the first and second electromagnetic heaters in the first heating assembly and the third and fourth electromagnetic heaters in the second heating assembly can be turned off.

[0105] In this embodiment, after the vehicle-mounted electronic device is turned on, it may switch from an operating state to a silent state. The silent state refers to the vehicle-mounted electronic device being turned off or in standby mode. During this time, the power of the vehicle-mounted electronic device also changes instantaneously; that is, when switching from an operating state to a silent state, the power of the vehicle-mounted electronic device drops rapidly. In other words, when the power of the vehicle-mounted electronic device changes instantaneously, its temperature may rise or fall sharply. A sharp rise in temperature can easily lead to malfunctions, while a sharp drop in temperature can easily lead to condensation, thereby endangering equipment safety. To solve this problem, this embodiment continues to monitor the liquid supply temperature in real time after the vehicle-mounted electronic device is turned on, so that temperature compensation can be performed when the temperature of the vehicle-mounted electronic device drops sharply, avoiding the risk of condensation.

[0106] like Figure 6 The diagram shown is a flowchart of a temperature compensation method according to another embodiment of this application.

[0107] Step S610: After turning on the vehicle electronic equipment, determine the coolant temperature change rate based on the real-time monitored coolant supply temperature.

[0108] Coolant temperature change rate refers to the rate at which the supply coolant temperature decreases per unit time after the vehicle's electronic equipment is turned on.

[0109] Furthermore, based on the two monitored supply temperatures and the two monitoring times, the temperature difference between the two monitored supply temperatures and the time difference between the two monitoring times can be determined; the ratio of the temperature difference to the time difference is determined as the coolant temperature change rate.

[0110] Step S620: When the coolant temperature change rate is greater than or equal to a preset change rate threshold, the coolant power requirement is determined based on the real-time monitored supply temperature and the coolant temperature threshold corresponding to the vehicle electronic device.

[0111] The rate of change threshold is used to measure the threshold at which the supply liquid temperature drops too quickly.

[0112] If the rate of change of coolant temperature is greater than or equal to the rate of change threshold, it indicates that the supply temperature is dropping too quickly, and the coolant needs to be reheated.

[0113] If the rate of change of coolant temperature is less than the threshold, it means that the rate of decrease of the supply temperature is acceptable, and the coolant does not need to be heated temporarily.

[0114] Coolant temperature threshold refers to the minimum supply temperature required for onboard electronic equipment to maintain its operating temperature range.

[0115] Coolant power demand refers to the power required to measure the temperature difference between the real-time monitored supply temperature and the corresponding coolant temperature threshold for onboard electronic devices.

[0116] For example, the power requirement for coolant can be calculated using the following formula: P'=C×ΔT1'; △T1'=T2-Tout; Where P' is the power required for the coolant, C is the specific heat capacity of the coolant, T2 is the minimum supply temperature required for the on-board electronic equipment to maintain its operating temperature range, and Tout is the real-time monitored supply temperature.

[0117] Step S630: Turn on the third and fourth electromagnetic heaters in the second heating assembly, and control the power and value of the third and fourth electromagnetic heaters in the second heating assembly to the power required by the coolant until the change in coolant temperature is less than the change rate threshold, then turn off the second electromagnetic assembly.

[0118] Furthermore, after turning on the vehicle electronic equipment, in order to prevent the vehicle electronic equipment from overheating, the cooling system can be activated to cool the coolant, so as to cool the vehicle electronic equipment through the coolant. When it is determined that the coolant temperature change rate is greater than or equal to the change rate threshold, the third and fourth electromagnetic heaters in the second heating assembly can be activated. At the same time as activating the third and fourth electromagnetic heaters in the second heating assembly, the frequency of the cooling system can be reduced according to the preset frequency adjustment value.

[0119] In this embodiment of the application, the heat generation of the vehicle electronic device drops sharply. If the cooling system frequency is reduced and the coolant is allowed to heat up, a long waiting time is required. During this waiting time, condensation may occur in the vehicle electronic device. Therefore, the second heating component can be turned on again to heat up the coolant to compensate and suppress condensation in the vehicle electronic device.

[0120] Vehicle-mounted electronic devices travel throughout the country with the vehicle. In low-temperature environments, if the ambient temperature is below the operating temperature threshold of the electronic devices, directly turning them on may cause malfunctions. In such cases, the temperature compensation method of this application embodiment can be used to preheat the electronic devices. After the electronic devices are started, their operating power may change drastically, leading to a rapid change in heat generation. For example, if the electronic devices switch from full-power operation to a silent state, their temperature will drop rapidly. In this situation, the temperature compensation method of this application embodiment can be used to compensate for changes in the liquid supply temperature, preventing condensation caused by excessively rapid changes in the liquid supply temperature.

[0121] This application embodiment also provides a temperature compensation device. The temperature compensation device of this application embodiment can be installed in the aforementioned controller, such as...

[0123] The temperature judgment module 720 is used to determine whether the real-time monitored liquid supply temperature is lower than the operating temperature threshold corresponding to the vehicle electronic device.

[0124] The first control module 730 is used to control the first heating component to heat the liquid supply pipeline when the judgment module determines that the real-time monitored liquid supply temperature is less than the operating temperature threshold corresponding to the vehicle electronic device; after the first heating component has been working continuously for a preset time period, the liquid supply pump is started and the first heating component and the second heating component are controlled to heat the liquid supply pipeline simultaneously.

[0125] The second control module 740 is used to control the vehicle electronic device to turn on and off the first heating component and the second heating component when the judgment module determines that the real-time monitored liquid supply temperature is greater than or equal to the operating temperature threshold corresponding to the vehicle electronic device.
