Description

Technical Field

[0001] The present application relates to the field of automotive technology, and in particular to an idle energy replenishment control method, device and vehicle. Background Art

[0002] Idle charging refers to a technology that uses excess energy generated by the engine to charge the battery pack while the vehicle is running and idling. When the vehicle is operating in a high-temperature environment, such as in a hot desert or at a summer campground, idling charging is performed. Due to the characteristics of the vehicle's operating conditions and the fact that it is not moving, the fan alone dissipates heat from the front-end module. This requires cooling the motor, passenger compartment, and battery, which deteriorates the heat exchange conditions of the low-temperature radiator. Furthermore, when the air conditioner is cooling the battery and passenger compartment, the condenser's heat load is excessive, causing the outside air to enter the low-temperature radiator and heat up. This in turn causes the low-temperature circuit water temperature to overheat, triggering thermal protection of various low-temperature circuit components, resulting in performance degradation or even failure. Furthermore, if the water temperature at the on-board charger (OBC) inlet rises and exceeds the limit, the DC / DC converter (DC / DC) will be limited, failing to meet the vehicle's low-voltage charge balance. This will cause the blower to experience abnormal airflow and ultimately prevent the vehicle from powering up after the ignition is turned off.

[0003] Therefore, how to provide an idle energy replenishment control method that can avoid the power limitation of the vehicle's DC / DC converter and ensure the low-voltage electrical balance of the vehicle has become a technical problem that technicians in this field urgently need to solve. Summary of the Invention

[0004] In view of the above problems, the present application provides a urea pump bench test method that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows:

[0005] An idle energy replenishment control method includes: determining whether a target vehicle meets high-power idle energy replenishment control conditions; obtaining vehicle status information of the target vehicle, the vehicle status information at least including inlet water temperature of an onboard charger and a DC / DC converter, high-pressure pressure of an air-conditioning line, and current air-conditioning compressor speed; obtaining ambient wind information of the target vehicle, the ambient wind information at least including wind direction information and wind speed information; and adjusting control parameters of target heat dissipation components in the target vehicle based on the ambient wind information and the vehicle status information, the heat dissipation components including at least one of a radiator, an electronic water pump, and an air-conditioning compressor.

[0006] After the idle energy replenishment control conditions are turned on, the heat dissipation components are adjusted by detecting the inlet water temperature of the on-board charger and DC / DC converter and the ambient wind information to control the temperature of various components in the vehicle and maintain the low-voltage power balance of the vehicle.

[0007] Optionally, the engine status, high-power idle energy replenishment mode status, air-conditioning status and ambient temperature of the target vehicle are obtained; it is determined whether the engine status of the target vehicle is in the starting state, and whether the high-power idle energy replenishment mode is in the on state, and the air-conditioning status is in the on state, and the ambient temperature is higher than a first preset threshold; if so, the target vehicle meets the high-power idle energy replenishment control condition, and the high-power idle energy replenishment mode is an energy replenishment mode with a charging power higher than a first power threshold; if not, the target vehicle does not meet the high-power idle energy replenishment control condition.

[0008] Optionally, the control parameters of the target heat dissipation components in the target vehicle are adjusted based on the ambient wind information and the vehicle status information, specifically including: if the inlet water temperature of the on-board charger and the DC / DC converter is lower than a first temperature threshold, or the high pressure of the air-conditioning pipeline is lower than a preset pressure threshold, the control parameters of the target heat dissipation components in the target vehicle are not adjusted, and the vehicle status information of the target vehicle is continuously monitored.

[0009] Optionally, based on the ambient wind information and the vehicle status information, the control parameters of the target heat dissipation components in the target vehicle are adjusted, specifically including: if the high pressure of the air-conditioning pipeline is higher than a preset pressure threshold, and the inlet water temperature of the on-board charger and the DC / DC converter is within a preset temperature range, then the radiator duty cycle and the electronic water pump duty cycle are increased, and the current speed of the air-conditioning compressor is maintained.

[0010] Optionally, adjusting the control parameters of the target heat dissipation components in the target vehicle based on the ambient wind information and the vehicle status information specifically includes: determining that the inlet water temperature of the on-board charger and the DC / DC converter is higher than a second temperature threshold; adjusting the control parameters of the target heat dissipation components in the target vehicle based on the inlet water temperature of the on-board charger and the DC / DC converter, and the ambient wind information.

[0011] Optionally, the adjusting of the control parameters of the target heat dissipation components in the target vehicle based on the inlet water temperature of the on-board charger and the DC / DC converter, and the ambient wind information specifically includes: determining an adjustment level corresponding to the control parameters of the target heat dissipation components based on the ambient wind information; continuously monitoring the inlet water temperature of the on-board charger and the DC / DC converter after adjusting the control parameters of the target heat dissipation components based on the adjustment level; adjusting the control parameters of the target heat dissipation components in the target vehicle according to the inlet water temperature of the on-board charger and the DC / DC converter after a preset running time; the adjusting of the control parameters of the target heat dissipation components corresponding to different adjustment levels includes at least one of: increasing the duty cycle of the radiator, increasing the duty cycle of the electronic water pump, and reducing the current speed of the air-conditioning compressor.

[0012] By selecting different control parameter adjustment strategies based on the ambient wind direction and speed, the accuracy of the temperature control solution can be improved. Since partial heat dissipation is achieved through ambient wind, resource loss during the cooling process is also reduced.

[0013] Optionally, after the preset running time, the control parameters of the target heat dissipation components in the target vehicle are adjusted according to the inlet water temperature of the on-board charger and the DC / DC converter, specifically including: after the preset running time, determining that the inlet water temperature of the on-board charger and the DC / DC converter is higher than a third temperature threshold; based on the adjustment level corresponding to the control parameters of the target heat dissipation components, adjusting the control parameters of the target heat dissipation components again, and monitoring the inlet water temperature of the on-board charger and the DC / DC converter; until the inlet water temperature of the on-board charger and the DC / DC converter is no higher than the third temperature threshold.

[0014] Optionally, after monitoring the inlet water temperature of the on-board charger and the DC / DC converter, the method further includes: if the inlet water temperature of the on-board charger and the DC / DC converter is still higher than a third temperature threshold; the target vehicle starts a low-power idle energy replenishment mode, and controls the parameters of the target heat dissipation components to a low-power idle energy replenishment strategy; the low-power idle energy replenishment mode is an energy replenishment mode in which the charging power is lower than a second preset threshold.

[0015] Optionally, before adjusting the control parameters of the target heat dissipation components in the target vehicle based on the ambient wind information and the vehicle status information, the method further includes: receiving an air-conditioning adjustment instruction from the user, and adjusting the air-conditioning compressor speed according to the air-conditioning adjustment instruction; after adjusting the air-conditioning compressor speed according to the air-conditioning adjustment instruction and adjusting the control parameters of other target heat dissipation components according to the idle energy replenishment control strategy, determining the inlet water temperature of the on-board charger and the DC / DC converter; if the inlet water temperature of the on-board charger and the DC / DC converter continues to be higher than a third temperature threshold; the target vehicle starts low-power idle energy replenishment, and adjusts the control parameters of the target heat dissipation components to the low-power idle energy replenishment strategy on the basis of maintaining the air-conditioning compressor speed unchanged.

[0016] During the temperature adjustment process, if an air conditioning adjustment instruction is received from the user, the user's needs will be met first. If the cooling needs of the components in the vehicle cannot be met at this time, the vehicle will be switched from high-power idle energy charging mode to low-power idle energy charging mode to ensure user experience.

[0017] The present application also provides an idle energy replenishment control device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute: determining that a target vehicle meets high-power idle energy replenishment control conditions; obtaining vehicle status information of the target vehicle, the vehicle status information at least including the inlet water temperature of the on-board charger and the DC / DC converter, the high-pressure pressure of the air-conditioning pipeline, and the current air-conditioning compressor speed; obtaining ambient wind information of the target vehicle, the ambient wind information at least including wind direction information and wind speed information; and adjusting control parameters of target heat dissipation components in the target vehicle based on the ambient wind information and the vehicle status information, the heat dissipation components including at least one of a radiator, an electronic water pump, and an air-conditioning compressor.

[0030] The following describes exemplary embodiments of the present application in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments shown herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0031] When a vehicle is operating in a high-temperature environment, such as in a hot desert or idling at a summer campsite, due to the characteristics of the vehicle's operating conditions and the lack of travel speed, the fan alone dissipates heat from the vehicle's front-end module. Cooling and dissipating heat must then be provided to areas such as the motor, passenger compartment, and battery, which can deteriorate the heat exchange conditions of the low-temperature radiator. Simultaneously, when the air conditioner is cooling the battery and passenger compartment, the condenser's heat load is excessive, causing the outside air to heat up when it enters the low-temperature radiator. This in turn causes the low-temperature circuit water temperature to overheat, leading to thermal protection of various low-temperature circuit components, resulting in performance degradation or even functional failure. Simultaneously, when the on-board charger (OBC) inlet water temperature rises and exceeds the limit, the DC / DC converter is limited in power, unable to maintain the vehicle's low-voltage charge balance, resulting in abnormal airflow from the blower and ultimately preventing the vehicle from powering on after the engine is turned off. Therefore, providing an idle charge control method that can avoid limiting the vehicle's DC / DC converter power and ensure low-voltage charge balance has become a technical problem urgently needed by those skilled in the art.

[0032] To this end, the present application provides an idle energy replenishment control method and device, wherein the idle energy replenishment control method is as follows: Figure 1 Shown, including:

[0033] S101: Determine whether a target vehicle meets high-power idle energy replenishment control conditions.

[0034] First, before implementing the idle energy replenishment control method, the controller in the vehicle must first determine whether the current state of the vehicle meets the idle energy replenishment control conditions. Only when the idle energy replenishment control conditions are met can the following idle energy replenishment control method be implemented.

[0035] In determining whether the vehicle meets the idle energy replenishment control conditions, it is necessary to obtain the engine status, high-power idle energy replenishment mode status, air conditioning status and ambient temperature of the target vehicle. At the same time, determine whether the engine status of the target vehicle is in the start-up state, whether the high-power idle energy replenishment mode is in the on state, and whether the air conditioning status is in the on state, and the ambient temperature is higher than the first preset threshold. In this application, the difference between the high-power idle energy replenishment mode and the low-power idle energy replenishment mode is that the high-power idle energy replenishment mode charges faster, but correspondingly causes the related components to heat up more seriously. If all of the above conditions are met, the target vehicle meets the idle energy replenishment control conditions. If at least one of the above conditions is not met, the target vehicle does not meet the idle energy replenishment control conditions. The high-power idle energy replenishment mode here is an energy replenishment mode with a charging power higher than the first power threshold (such as 60kW).

[0036] like Figure 2 As shown, when determining whether the vehicle meets the high-power idle energy replenishment control conditions, you can follow the following steps:

[0037] S1011: The vehicle is in the engine starting state.

[0038] S1012: The controller monitors the vehicle driving status.

[0039] S1013: The controller determines whether the vehicle is in high-power idle charging mode and the air conditioner is on.

[0040] S1014: If the vehicle does not have the high-power idle energy charging mode turned on, or the air conditioner is not turned on, the high-power idle energy charging control method is not executed.

[0041] S1015: If the vehicle has high-power idle energy replenishment turned on and the air conditioner is on, the controller monitors the ambient temperature T0.

[0042] S1016: The controller determines whether the ambient temperature T0 is not lower than a first preset threshold.

[0043] S1017: If the ambient temperature T0 is lower than the first preset threshold, the high-power idle energy replenishment control method is not executed.

[0044] S1018: If the ambient temperature T0 is not lower than the first preset threshold, execute the high-power idle energy replenishment control method.

[0045] S102: Acquire vehicle status information of the target vehicle.

[0046] After determining that the target vehicle meets the idle energy replenishment control conditions, it is necessary to obtain the vehicle status information of the target vehicle. The vehicle status information here refers to the information on the temperature of each component of the target vehicle, especially the component status information related to the component temperature when the vehicle is in a high-power idle energy replenishment state. Such as the inlet water temperature of the on-board charger and the DC / DC converter, the high pressure of the air-conditioning pipeline, and the current air-conditioning compressor speed. It should be noted that the inlet water temperature of the on-board charger and the DC / DC converter here refers to the higher water temperature of the on-board charger inlet water temperature and the inlet water temperature of the DC / DC converter. For the convenience of naming, this application will explain them together.

[0047] S103: Acquire ambient wind information of the target vehicle.

[0048] When the vehicle is performing high-power idling recharging, since the vehicle is not moving, it only relies on the vehicle's internal radiator and electronic water pump for heat dissipation. The radiator here is used to dissipate heat for the front-end module, and its specific implementation method can be a fan. The electronic water pump refers to a low-temperature circuit electronic water pump. The fan and the low-temperature circuit electronic water pump are used for illustration in the following embodiments. It can be understood that the faster the fan speed, the higher the heat dissipation efficiency of the front-end module. At the same time, the higher the power of the low-temperature circuit electronic water pump, the faster the coolant flows and the lower the temperature inside the vehicle. However, when there is ambient wind around the vehicle, the ambient wind will also help the vehicle dissipate heat. Therefore, when determining the temperature control strategy, the influence of the ambient wind should be considered. The ambient wind information here at least includes wind direction information and wind speed information.

[0049] S104: Adjusting control parameters of target heat dissipation components in the target vehicle based on the ambient wind information and the vehicle status information.

[0050] After determining the ambient wind information and vehicle status information, in order to maintain the temperature of important components inside the vehicle within the ideal temperature range, it is necessary to implement a temperature control strategy for the heat dissipation-related components in the vehicle. The heat dissipation components here include fans, low-temperature circuit electronic water pumps, air-conditioning compressors and other components. The control parameters include fan duty cycle, low-temperature circuit electronic water pump duty cycle, air-conditioning compressor speed and other parameters. The ideal temperature range here refers to the ideal operating temperature corresponding to each component. For example, for each component in the low-temperature circuit, the ideal temperature range refers to the temperature range that can maintain the low-temperature circuit water temperature balance and will not cause thermal protection of the low-temperature circuit components. For the on-board charger and DC / DC converter, it is the temperature range that can meet the low-voltage power balance of the vehicle and will not cause abnormal power in the blower, such as a temperature below 65°C.

[0051] In one embodiment, when adjusting the control parameters of a target heat dissipation component, the control parameters of the heat dissipation component are first determined based on the vehicle status information to determine whether the current temperature is high or is trending upward. The control parameters of the heat dissipation component are then adjusted. Specifically, if the inlet water temperature of the onboard charger and DC / DC converter is low, or if the high pressure in the air conditioning line is low, indicating that the temperature of the relevant components in the vehicle is low, the control parameters of the target heat dissipation component do not need to be adjusted. However, the vehicle status information of the target vehicle needs to be continuously monitored.

[0052] Here we explain the above-mentioned words such as lower and higher. The staff can set corresponding thresholds for various types of parameters. When the parameters are higher or lower than the preset thresholds, different strategies will be implemented. For example, when the inlet water temperature of the on-board charger and the DC / DC converter is lower than the first temperature threshold, or the high pressure of the air-conditioning pipe is lower than the preset pressure threshold, the control parameters of the target heat dissipation components in the target vehicle will not be adjusted. Specifically, at this time, the first temperature threshold can be 60°C, and the preset pressure threshold can be 2.1Mpa. The process of whether the control parameters of the target heat dissipation components need to be adjusted at this time is as follows Figure 3 As shown, the steps include:

[0053] S301: Determine the target vehicle to execute the idle energy replenishment control method.

[0054] S302: Monitor the OBC & DC / DC inlet water temperature T1, the air conditioning pipeline high pressure P1, and the air conditioning compressor speed N.

[0055] S303: Determine whether the OBC&DC / DC inlet water temperature T1 is less than 60°C, or the air conditioning pipeline high pressure P1 is less than 2.1 MPa.

[0056] S304: If the OBC&DC / DC inlet water temperature T1 is less than 60°C, or the air conditioning pipeline high pressure P1 is less than 2.1 MPa, the control parameters of the target heat dissipation component are not adjusted.

[0057] S305: If the OBC&DC / DC inlet water temperature T1 ≥ 60°C and the air conditioning pipeline high pressure P1 < 2.1 MPa, adjust the control parameters of the target heat dissipation component.

[0058] In one embodiment, after confirming that the control parameters of the target cooling component need to be adjusted, the vehicle status information within the target vehicle is continuously monitored. If the high pressure of the air conditioning line is higher than a preset pressure threshold, and the water temperature at the inlet of the onboard charger and the DC / DC converter is within a preset temperature range (the preset temperature range refers to a temperature range where the temperature is relatively high but below the warning temperature), then since the temperature is approaching the warning temperature, the cooling components within the target vehicle need to be controlled, for example, by increasing the fan duty cycle and the low-temperature circuit electronic water pump duty cycle, while maintaining the current speed of the air conditioning compressor. The endpoints of the preset temperature range may be a first temperature threshold and a second temperature threshold, where the second temperature threshold may be 62°C. In this case, increasing the radiator duty cycle and the low-temperature circuit electronic water pump duty cycle refers to increasing the radiator duty cycle and the low-temperature circuit electronic water pump duty cycle from their current duty cycle to a preset duty cycle threshold, for example, increasing the radiator duty cycle to the first preset duty cycle threshold and increasing the low-temperature circuit electronic water pump duty cycle to the second preset duty cycle threshold. Here, the first preset duty cycle threshold value may be 90%, and the second preset duty cycle threshold value may be 70%. Then, the process of adjusting the control parameters of the target heat dissipation component is as follows: Figure 4 As shown, there is no need to consider the impact of ambient wind on the heat dissipation of components in the target vehicle.

[0059] In one embodiment, when the target vehicle's vehicle status information indicates that the water temperature at the onboard charger and DC / DC converter inlets is too high, for example, above a second temperature threshold, radiator components need to be controlled to reduce these temperatures to prevent the DC / DC converter from limiting power and failing to meet the vehicle's low-voltage charge balance. To conserve energy, the impact of ambient wind on the heat dissipation process needs to be considered. Therefore, control parameters of target heat dissipation components within the target vehicle need to be adjusted based on the water temperature at the onboard charger and DC / DC converter inlets, as well as the ambient wind information.

[0060] Specifically, if ambient wind is considered as a factor affecting the target vehicle, the presence of ambient wind, as well as its direction and speed, must be considered. If the ambient wind is headwind and the wind speed is high, the adjustment of the control parameters of the vehicle's internal radiator components can be slightly slowed down, hoping that the ambient wind will remove more heat, thereby reducing the number of adjustments and energy consumption. Furthermore, the urgency and priority of the adjustment measures can be determined based on ambient wind information and vehicle status information. The higher the adjustment level, the more necessary the adjustment of the radiator component control parameters is, i.e., the lower the priority of the adjustment strategy, such as adjusting the duty cycle of the low-temperature circuit electronic water pump. After adjusting the radiator component control parameters, the inlet water temperature of the onboard charger and DC / DC converter must be continuously monitored. After a preset time for adjusting the control parameters, the control parameters of the target cooling components in the target vehicle are adjusted again based on the inlet water temperature of the onboard charger and DC / DC converter, hoping that the inlet water temperature of the onboard charger and DC / DC converter remains below a third temperature threshold (e.g., below 65°C). In this application, the adjustment levels are roughly as follows: increasing the fan duty cycle, increasing the low-temperature circuit electronic water pump duty cycle, and reducing the current air conditioning compressor speed. During the adjustment process, the duty cycles of the fan and low-temperature circuit electronic water pump are prioritized. If, after increasing the duty cycles of both the fan and low-temperature circuit electronic water pump to 90%, it is still necessary to cool the inlet water temperature of the on-board charger and DC / DC converter in the vehicle, the current air conditioning compressor speed is reduced.

[0061] Furthermore, if after adjusting the control parameters of the target heat dissipation components, the inlet water temperature of the vehicle charger and the DC / DC converter is still higher than the third temperature threshold, it means that under the current environmental conditions, if the high-power idle energy replenishment mode is to be turned on, even if the control parameters of the target heat dissipation components are adjusted, it cannot be guaranteed that the temperature of the relevant components is within the ideal range. At this time, in order to avoid deteriorating the heat exchange conditions of the low-temperature radiator and ensure that the low-voltage power balance of the vehicle is met, the high-power idle energy replenishment mode of the target vehicle is converted to a low-power idle energy replenishment mode, and the control parameters of the target heat dissipation components are adjusted to the low-power idle energy replenishment strategy. The low-power idle energy replenishment mode here is an energy replenishment mode in which the charging power is lower than the second power threshold (such as 20kW).

[0062] It should be noted that this mode changeover is automatically switched by the vehicle controller based on vehicle status information. After the automatic switchover, a notification is sent to passengers inside the vehicle, such as on the vehicle's display or via voice announcement. If a passenger then sends a control command to re-enter high-power idle charging mode, the controller will re-monitor vehicle driving status and other information to determine whether the target vehicle meets the conditions for high-power idle charging control method.

[0063] At the same time, the air conditioning compressor speed is adjusted during the control parameter adjustment process, reducing vehicle cooling capacity and causing the cabin temperature to rise. If a passenger perceives the cabin temperature as too high, they may adjust the air conditioning compressor speed in an attempt to lower the cabin temperature. The passenger's control command takes precedence. If, after adjusting the air conditioning compressor speed based on the passenger's control command, the temperature remains above the third temperature threshold, the vehicle cannot simultaneously meet both the high-power idle charging demand and the passenger's cabin cooling needs. The vehicle will then switch from high-power idle charging mode to low-power idle charging mode, and the passengers will be notified. Subsequently, if the customer manually switches back to high-power idle charging mode, or if the air conditioning cooling demand decreases (i.e., the controller detects a decrease in compressor speed), the vehicle controller will resume high-power idle charging.

[0064] The following embodiment is used to illustrate the method of adjusting the control parameters of the target heat dissipation components: In one embodiment, if the inlet water temperature of the vehicle charger and the DC / DC converter is not lower than the second temperature threshold, the vehicle-mounted ultrasonic anemometer is monitored to determine the wind direction and wind speed information of the target vehicle.

[0065] If the target vehicle is in a tailwind state, the fan duty cycle and the low-temperature circuit electronic water pump duty cycle are adjusted to a first preset duty cycle, and the current speed of the air-conditioning compressor is maintained unchanged; after running for a preset time, the inlet water temperature T2 of the on-board charger and the DC / DC converter is monitored. If the inlet water temperature T2 of the on-board charger and the DC / DC converter is less than the second temperature threshold, the current control parameters of each target radiator are maintained, and the inlet water temperature of the on-board charger and the DC / DC converter, the high pressure of the air-conditioning pipe, and the speed of the air-conditioning compressor are continuously monitored. If the inlet water temperature T2 of the on-board charger and the DC / DC converter is not less than the second temperature threshold, determine whether the inlet water temperature of the on-board charger and the DC / DC converter is lower than the third temperature threshold; if the inlet water temperature T2 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, reduce the speed of the air-conditioning compressor; after running for a preset time, obtain the inlet water temperature T3 of the on-board charger and the DC / DC converter. If the inlet water temperature T3 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, maintain the current control parameters of each target radiator, and continuously monitor the inlet water temperature of the on-board charger and the DC / DC converter, the high pressure of the air-conditioning pipe and the speed of the air-conditioning compressor; if the inlet water temperature T2 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, reduce the speed of the air-conditioning compressor; after running for a preset time, obtain the inlet water temperature T3 of the on-board charger and the DC / DC converter. If the inlet water temperature T3 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, maintain the control parameters of the current target radiators, and continuously monitor the inlet water temperature of the on-board charger and the DC / DC converter, the high pressure of the air-conditioning pipe and the speed of the air-conditioning compressor; If the inlet water temperature T3 of the DC / DC converter is not lower than the third temperature threshold, the air-conditioning compressor speed is reduced again; after the preset running time, the inlet water temperature T4 of the vehicle charger and the DC / DC converter is obtained; if the inlet water temperature T4 of the vehicle charger and the DC / DC converter is lower than the third temperature threshold, the current control parameters of each target radiator are maintained, and the inlet water temperature of the vehicle charger and the DC / DC converter, the high pressure pressure of the air-conditioning pipe and the air-conditioning compressor speed are continuously monitored; if the inlet water temperature T4 of the vehicle charger and the DC / DC converter is not lower than the third temperature threshold, the high-power idle energy charging mode of the target vehicle is converted to the low-power idle energy charging mode, and the control parameters of the target heat dissipation components are adjusted to the low-power idle energy charging strategy. If the inlet water temperature T2 of the on-board charger and the DC / DC converter is not lower than the third temperature threshold, the air-conditioning compressor speed is significantly reduced; after the preset running time, the inlet water temperature T5 of the on-board charger and the DC / DC converter is obtained; if the inlet water temperature T5 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, the current control parameters of each target radiator are maintained, and the inlet water temperature of the on-board charger and the DC / DC converter, the high pressure pressure of the air-conditioning pipe and the air-conditioning compressor speed are continuously monitored; if the inlet water temperature T5 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, the high-power idle energy charging mode of the target vehicle is converted to a low-power idle energy charging mode, and the control parameters of the target cooling components are adjusted to the low-power idle energy charging strategy.If the first preset duty cycle is 90%, the preset time is 30s, the second temperature threshold is 62°C, and the third temperature threshold is 65°C are brought into the above process, the following can be obtained. Figure 5 The target heat dissipation component control parameter adjustment process is shown.

[0066] The above process is explained below: Since the vehicle is not facing headwind, the natural wind has little impact on the inlet water temperature of the onboard charger and DC / DC converter, so it is not considered. When reducing the air conditioning compressor speed, a PID-like control strategy is used. The speed reduction is determined based on the temperature difference between the current inlet water temperature of the onboard charger and DC / DC converter and the target temperature. After the speed reduction is achieved, the compressor speed is adjusted again based on the reduced temperature difference to achieve the appropriate speed. If the compressor speed before the reduction is N, the reduced speed can be expressed as Nn. If the compressor speed is reduced further, the compressor speed can be expressed as N-2n. The significant reduction in the compressor speed mentioned above directly reduces the compressor speed to N-2n.

[0067] In one embodiment, if the target vehicle is in a headwind state and the wind speed V of the ambient wind is lower than the first wind speed threshold at this time, that is, when the ambient wind is relatively small, the fan duty cycle is increased to the first preset duty cycle, the low-temperature circuit electronic water pump duty cycle is increased to the third preset duty cycle, and the current speed of the air-conditioning compressor is maintained unchanged; after running for a preset time, the inlet water temperature T6 of the on-board charger and the DC / DC converter is obtained; if the inlet water temperature T6 of the on-board charger and the DC / DC converter is less than the second temperature threshold, the control parameters of the current target radiators are maintained, and the inlet water temperature of the on-board charger and the DC / DC converter, the high pressure pressure of the air-conditioning pipeline and the speed of the air-conditioning compressor are continuously monitored; if the inlet water temperature T6 of the on-board charger and the DC / DC converter is less than the second temperature threshold, the control parameters of the current target radiators are maintained, and the inlet water temperature of the on-board charger and the DC / DC converter, the high pressure pressure of the air-conditioning pipeline and the speed of the air-conditioning compressor are continuously monitored; If T6 is greater than or equal to the second temperature threshold and less than the third temperature threshold, the duty cycle of the low-temperature circuit electronic water pump is increased to the first preset duty cycle. After running for a preset time, the inlet water temperature T7 of the on-board charger and the DC / DC converter is obtained; if the inlet water temperature T7 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, the control parameters of the current target radiators are maintained, and the inlet water temperature of the on-board charger and the DC / DC converter, the high pressure pressure of the air-conditioning pipeline and the speed of the air-conditioning compressor are continuously monitored; if the inlet water temperature T6 of the on-board charger and the DC / DC converter is not less than the third temperature threshold, or T7 is lower than the third temperature threshold, the speed of the air-conditioning compressor is adjusted according to the above-mentioned tailwind state process, and the vehicle status information is continuously monitored. If the first wind speed threshold of 5m / s and the third preset duty cycle of 80% are substituted into the above process, the control parameter adjustment process of the above-mentioned target radiator is as follows: Figure 6 By comparison Figure 5 and Figure 6 As can be seen from the content, compared with the tailwind state, when the vehicle is in the headwind state, the technical solution provided by this application is more likely to rely on the temperature control function of the ambient wind. Figure 5 Temperature control strategy, Figure 6 The regulatory strategy in is more gentle.

[0068] In one embodiment, if the target vehicle is facing a headwind and the ambient wind speed V is not less than a first wind speed threshold, i.e., when the ambient wind is strong, the vehicle's current strategy may be maintained for a preset time, and the inlet water temperature T8 of the onboard charger and DC / DC converter may be continuously monitored. If, after the preset time, the inlet water temperature T8 of the onboard charger and DC / DC converter falls below a second temperature threshold, the current control parameters of each target radiator are maintained, and the vehicle status information of the target vehicle is continuously monitored. If the inlet water temperature T8 of the onboard charger and DC / DC converter falls between the second and third temperature thresholds, the fan duty cycle is increased to the first preset duty cycle, the low-temperature circuit electronic water pump duty cycle is increased to the second preset duty cycle, and the air conditioner compressor maintains its current speed. If the inlet water temperature T8 of the onboard charger and DC / DC converter is not less than the third temperature threshold, the controller controls the fan duty cycle to increase to the first preset duty cycle, the low-temperature circuit electronic water pump duty cycle to increase to the third preset duty cycle, and the air conditioner compressor maintains its current speed. Then, after running for a preset time, obtain the inlet water temperature T9 of the on-board charger and the DC / DC converter; if the inlet water temperature T9 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, maintain the current control parameters of each target radiator, and continuously monitor the vehicle status information of the target vehicle. If the inlet water temperature T9 of the on-board charger and the DC / DC converter is not lower than the third temperature threshold, adjust the duty cycle of the low-temperature circuit electronic water pump to increase to the first preset duty cycle; after running for a preset time, obtain the inlet water temperature T10 of the on-board charger and the DC / DC converter; if the inlet water temperature T10 of the on-board charger and the DC / DC converter is lower than the third temperature threshold, maintain the current control parameters of each target radiator, and continuously monitor the vehicle status information of the target vehicle; if the inlet water temperature T10 of the on-board charger and the DC / DC converter is not lower than the third temperature threshold, adjust the air-conditioning compressor speed according to the above-mentioned tailwind state process, and continuously monitor the vehicle status information. At this time, the control parameter adjustment process of the target radiator is as follows: Figure 7 shown.

[0069] Here, the process of "adjusting the speed of the air-conditioning compressor" in the above two embodiments is described. Figure 5The process corresponding to "62°C ≤ T2 < 65°C" in the figure reduces the air conditioner compressor speed to Nn. After a preset time, the system monitors the inlet water temperature T3 of the onboard charger and DC / DC converter. If T3 is less than 65°C, the control parameters of the target radiators are maintained, and the target vehicle's status information is continuously monitored. If T3 is ≥ 65°C, the air conditioner compressor speed is reduced again, to N-2n. After a preset time, the system monitors the inlet water temperature T4 of the onboard charger and DC / DC converter. If T4 is less than 65°C, the control parameters of the target radiators are maintained, and the target vehicle's status information is continuously monitored. If T4 is ≥ 65°C, the target vehicle's high-power idle charging mode is switched to low-power idle charging mode, and the control parameters of the target cooling components are adjusted to the low-power idle charging strategy.

[0070] This application provides a control method for vehicle idle charging. By detecting the vehicle's charging power, ambient temperature, OBC & DC / DC inlet water temperature, air conditioning pressure, and wind direction and speed signals, it controls the duty cycle of the fan and low-temperature circuit electronic water pump during vehicle idle charging, removing heat from the condenser, low-temperature radiator, and high-temperature radiator. If the heat dissipation demand cannot be met, the compressor speed is controlled to reduce the condenser heat, thereby lowering the air temperature entering the low-temperature radiator. This minimizes DC / DC power limiting and ensures low-voltage electrical balance in the vehicle.
