Description
Technical Field
[0001] The present application relates to the field of automobile technology, and in particular to an idle energy replenishment control method, device and vehicle. Background Art
[0002] Idle energy replenishment refers to the technology of using the excess energy generated by the engine to charge the battery pack when the vehicle is not turned off and the engine is in an idling state. When the vehicle is running in a high-temperature environment, such as in a hot desert, or when idling energy replenishment at a summer camping site, due to the characteristics of the vehicle's operating conditions and without driving, the fan is the only one that dissipates heat from the vehicle's front-end module. At this time, the motor, passenger compartment, battery and other areas need to be cooled and dissipated, which will cause the heat exchange conditions of the low-temperature radiator to deteriorate. At the same time, when the air conditioner cools the battery and passenger compartment, the condenser heat load is too high, which will cause the outside wind to enter the low-temperature radiator. The wind temperature will rise, which will cause the low-temperature circuit water temperature to overheat, resulting in thermal protection of various components of the low-temperature circuit, resulting in performance degradation or even functional failure. At the same time, the on-board charger (OBC) inlet water temperature rises. When it exceeds the limit, the DC / DC converter (DC / DC) will be limited in power, unable to meet the vehicle's low-voltage power balance, resulting in abnormal air volume in the blower, and ultimately causing the vehicle to be unable to power on after the engine 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 technical personnel in this field urgently need to solve. Summary of the invention

[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 replenishment mode to low-power idle energy replenishment mode to ensure user experience.

[0030] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the 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 of the parameters herein. On the contrary, these embodiments are provided in order 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 the vehicle is running in a high temperature environment, such as in a high temperature desert, when idling and recharging at a summer camping site, due to the characteristics of the vehicle's operating conditions and without driving speed, the fan is used to dissipate heat from the vehicle's front-end module. At this time, the motor, passenger compartment, battery and other areas need to be cooled and dissipated, which will cause the heat exchange conditions of the low-temperature radiator to deteriorate. At the same time, when the air conditioner cools the battery and the passenger compartment, the condenser heat load is too high, which will cause the wind temperature to rise when the outside wind enters the low-temperature radiator, and then cause the low-temperature circuit water temperature to overheat, resulting in thermal protection of various components of the low-temperature circuit, thereby reducing performance and even functional failure. At the same time, the on-board charger (On-Board Charger, OBC) inlet water temperature rises, and after exceeding the limit value, the DC / DC converter will be limited in power, unable to meet the low-voltage power balance of the vehicle, resulting in abnormal air volume in the blower, and ultimately causing the vehicle to be unable to power on after the vehicle is turned off. Therefore, how to provide an idle energy recharge control method that can avoid the power limit of the vehicle DC / DC converter and ensure the low-voltage power balance of the vehicle has become a technical problem that technicians in this field need to solve urgently.
[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 As shown, including:
[0033] S101: Determine whether the target vehicle meets the high-power idle energy replenishment control condition.
[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 target vehicle's engine state, high-power idle energy replenishment mode state, air conditioning state, and ambient temperature. At the same time, determine whether the target vehicle's engine state is in the start state, and whether the high-power idle energy replenishment mode is in the on state, and the air conditioning state 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 judging whether the vehicle meets the high-power idle energy replenishment control conditions, the following steps can be followed:
[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 energy replenishment mode and the air conditioner is on.
[0040] S1014: If the high-power idle energy replenishment mode is not turned on for the vehicle, or the air conditioner is not turned on, the high-power idle energy replenishment 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, the high-power idle energy replenishment control method is executed.
[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 inlet water temperature of the on-board charger and the inlet water temperature of the DC / DC converter. For the convenience of calling, this application will explain them together.
[0047] S103: Acquire the ambient wind information of the target vehicle.
[0048] When the vehicle is performing high-power idling energy replenishment, since the vehicle is not driving, it only relies on the vehicle's internal radiator and electronic water pump to dissipate heat. Here, the radiator 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 to dissipate heat. Therefore, when determining the temperature control strategy, the influence of the ambient wind should be considered. Here, the ambient wind information at least includes the 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 a 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 the target heat dissipation component, it is first necessary to determine whether the current temperature is high or there is a tendency for the temperature to rise based on the vehicle status information, and then adjust the control parameters of the heat dissipation component. Specifically, if the inlet water temperature of the on-board charger and the DC / DC converter is low, or the high pressure of the air conditioning pipeline is low, it means that the temperature of the relevant components in the vehicle is low at this time, and there is no need to adjust the control parameters of the target heat dissipation component, but it is necessary to continuously monitor the vehicle status information of the target vehicle.
[0052] Here we explain the above-mentioned words such as lower and higher. The staff can set corresponding thresholds for various types of parameters, and implement different strategies when the parameters are higher or lower than the preset thresholds. 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 pipeline 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 2.1MPa.
[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 2.1MPa, the control parameters of the target heat dissipation components are not adjusted.
[0057] S305: If the OBC&DC / DC inlet water temperature T1 ≥ 60°C and the air conditioning pipeline high pressure P1 < 2.1MPa, adjust the control parameters of the target heat dissipation components.
[0058] In one embodiment, after confirming that the control parameters of the target heat dissipation components need to be adjusted, the vehicle status information in the target vehicle is continuously monitored. If the high pressure of the air conditioning pipeline is higher than the preset pressure threshold, and the inlet water temperature of the on-board charger and the DC / DC converter is within the preset temperature range, the preset temperature range here refers to the temperature range where the temperature is relatively high but has not yet reached the warning temperature. At this time, since the temperature is close to the warning temperature, it is necessary to control the heat dissipation components in the target vehicle, such as increasing the fan duty cycle and the low temperature circuit electronic water pump duty cycle, and maintaining the current speed of the air conditioning compressor. The endpoints of the preset temperature range can be the first temperature threshold and the second temperature threshold, and the second temperature threshold can be 62°C. At this time, 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 the current duty cycle to a preset preset duty cycle threshold, for example, here the radiator duty cycle is increased to the first preset duty cycle threshold, and the low temperature circuit electronic water pump duty cycle is increased to the second preset duty cycle threshold. Here, the first preset duty cycle threshold may be 90%, and the second preset duty cycle threshold may be 70%. At this time, 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 effect of ambient wind on the heat dissipation of components in the target vehicle.
[0059] In one embodiment, when the inlet water temperature of the onboard charger and the DC / DC converter is too high in the vehicle status information corresponding to the target vehicle, for example, higher than the second temperature threshold, the radiator components need to be controlled to reduce the inlet water temperature of the onboard charger and the DC / DC converter to prevent the DC / DC converter from limiting power and failing to meet the low-voltage power balance of the vehicle. In order to save energy consumption, the influence of ambient wind on the heat dissipation process needs to be considered at this time. Therefore, the control parameters of the target heat dissipation components in the target vehicle need to be adjusted based on the inlet water temperature of the onboard charger and the DC / DC converter, as well as the ambient wind information.
[0060] Specifically, if the environmental wind factor is to be used as an influence on the target vehicle, it is necessary to consider whether there is environmental wind, as well as the wind direction and wind speed of the environmental wind. If the wind direction of the environmental wind is against the wind and the wind speed is high, the adjustment of the control parameters of the radiator components inside the vehicle can be slightly slowed down at this time, in the hope that the environmental wind can take away more heat, thereby reducing the number of adjustments and reducing energy consumption. At the same time, the adjustment level of the adjustment measures of the radiator component control parameters can be divided according to the urgency and priority of the adjustment measures based on the environmental wind information and the vehicle status information. The higher the adjustment level, the more necessary it is to adjust the control parameters of the radiator components at this time, that is, the lower the priority of the adjustment strategy, such as adjusting the duty cycle of the low-temperature circuit electronic water pump to a higher level. After adjusting the control parameters of the radiator components, it is necessary to continuously monitor the inlet water temperature of the on-board charger and the DC / DC converter; and after adjusting the preset time of the control parameters, the control parameters of the target heat dissipation components in the target vehicle are adjusted again according to the inlet water temperature of the on-board charger and the DC / DC converter, in the hope that the inlet water temperature of the on-board charger and the DC / DC converter can be maintained below the third temperature threshold (such as below 65°C). In this application, the adjustment levels are as follows: increase the fan duty cycle, increase the low-temperature circuit electronic water pump duty cycle, and reduce the current speed of the air-conditioning compressor. During the adjustment process, the duty cycle of the fan and the low-temperature circuit electronic water pump is increased first. If the duty cycle of the fan and the low-temperature circuit electronic water pump is increased to 90%, it is still necessary to cool the inlet water temperature of the on-board charger and the DC / DC converter in the vehicle, then reduce the current speed of the air-conditioning compressor.
[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 not to deteriorate 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 set to a 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 the conversion mode is automatically switched by the vehicle controller according to the vehicle status information. After the automatic switching, a notification will be sent to the passengers in the car, such as displaying on the car display screen or through voice broadcast prompts. If the passenger sends a control command at this time and hopes to re-enter the high-power idle energy replenishment mode, the controller will re-monitor the vehicle driving status and other information to determine whether the target vehicle meets the conditions of the high-power idle energy replenishment control method.
[0063] At the same time, since the speed of the air-conditioning compressor will be adjusted during the process of adjusting the control parameters, this will lead to a reduction in the cooling capacity in the vehicle, thereby causing the temperature of the passenger compartment inside the vehicle to rise. If the passenger thinks that the temperature in the passenger compartment is too high, the air-conditioning compressor speed will be adjusted in the hope of reducing the temperature in the passenger compartment. At this time, the passenger's control command has the highest priority. If the temperature is always higher than the third temperature threshold after the speed of the air-conditioning compressor is adjusted according to the passenger's control command, it means that the vehicle cannot meet the high-power idle energy replenishment demand and the passenger's in-vehicle cooling demand at the same time. The target vehicle will be switched from the high-power idle energy replenishment mode to the low-power idle energy replenishment mode, and the passengers in the passenger compartment will be informed. Afterwards, if the customer manually sets it to the high-power idle energy replenishment mode; or the air-conditioning cooling demand decreases, that is, when the controller recognizes that the compressor speed has decreased, the vehicle controller turns on the high-power idle energy replenishment.
[0064] The following embodiments are 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 the 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 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 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 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 pressure of the air-conditioning pipeline, and the speed of the air-conditioning compressor; if the on-board charger and the DC / If the inlet water temperature T3 of the DC converter is not lower than the third temperature threshold, the air-conditioning compressor speed is reduced again; after running for a preset time, the inlet water temperature T4 of the on-board charger and the DC / DC converter is obtained; if the inlet water temperature T4 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 air-conditioning compressor speed are continuously monitored; if the inlet water temperature T4 of the on-board charger and the DC / DC converter is not lower than the third temperature threshold, the high-power idle energy replenishment mode of the target vehicle is converted to the low-power idle energy replenishment mode, and the control parameters of the target heat dissipation components are set to the low-power idle energy replenishment 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 greatly reduced; after running for a preset 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 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 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 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.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 now explained: In the above process, since the vehicle is not in a headwind state, the natural wind has little effect on the control of the inlet water temperature of the on-board charger and the DC / DC converter, so it is not considered. When reducing the speed of the air-conditioning compressor, a control strategy similar to PID is used. It is necessary to determine the reduction in speed based on the temperature difference between the current inlet water temperature of the on-board charger and the DC / DC converter and the target temperature. After reducing the corresponding range, the compressor speed will be adjusted again according to the reduced temperature difference to adjust the compressor speed to the appropriate speed. If the air-conditioning compressor speed is N before the reduction, the compressor speed after the reduction can be expressed as Nn. If the air-conditioning compressor speed is reduced again, the compressor speed at this time can be expressed as N-2n. The above-mentioned significant reduction in the air-conditioning compressor speed directly reduces the air-conditioning 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, that is, 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 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, and 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 downwind 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 It can be seen from the content that compared with the tailwind state, when the vehicle is in the headwind state, the technical solution provided by this application is more expected to rely on the temperature control function of the ambient wind. Figure 5 The temperature control strategy Figure 6 The regulatory strategy in is more gentle.
[0068] In one embodiment, if the target vehicle is in a headwind state, and the wind speed V of the ambient wind is not lower than the first wind speed threshold, that is, when the ambient wind is relatively strong, the current strategy of the vehicle can be maintained for a preset time, and the inlet water temperature T8 of the onboard charger and the DC / DC converter is continuously monitored; if the inlet water temperature T8 of the onboard charger and the DC / DC converter is lower than the second temperature threshold after the preset time, the control parameters of the current target radiators 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 the DC / DC converter is between the second temperature threshold and the third temperature threshold, the fan duty cycle is controlled to be 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 conditioning compressor maintains the current speed unchanged; if the inlet water temperature T8 of the onboard charger and the DC / DC converter is not lower than the third temperature threshold, the controller controls the fan duty cycle to be 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 air conditioning compressor maintains the current speed unchanged. Then, after running for a preset time, the inlet water temperature T9 of the on-board charger and the DC / DC converter is obtained; if the inlet water temperature T9 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 vehicle status information of the target vehicle is continuously monitored. If the inlet water temperature T9 of the on-board charger and the DC / DC converter is not lower than the third temperature threshold, the duty cycle of the low-temperature circuit electronic water pump is adjusted to the first preset duty cycle; after running for a preset time, the inlet water temperature T10 of the on-board charger and the DC / DC converter is obtained; if the inlet water temperature T10 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 vehicle status information of the target vehicle is continuously monitored; if the inlet water temperature T10 of the on-board charger and the DC / DC converter is not lower than the third temperature threshold, the air-conditioning compressor speed is adjusted according to the above-mentioned downwind state process, and the vehicle status information is continuously monitored. 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 conditioner compressor" in the above two embodiments is described. Figure 5The process corresponding to "62℃≤T2<65℃" in the above is to reduce the speed of the air-conditioning compressor, at which time the speed of the air-conditioning compressor is Nn; after running for a preset time, monitor the inlet water temperature T3 of the on-board charger and the DC / DC converter; if the inlet water temperature T3 is less than 65℃, maintain the control parameters of the current target radiators, and continuously monitor the vehicle status information of the target vehicle. If the inlet water temperature T3≥65℃, reduce the speed of the air-conditioning compressor again, at which time the speed of the air-conditioning compressor is N-2n. After running for a preset time, monitor the inlet water temperature T4 of the on-board charger and the DC / DC converter, if the inlet water temperature T4 is less than 65℃, maintain the control parameters of the current target radiators, and continuously monitor the vehicle status information of the target vehicle. If the inlet water temperature T4≥65℃, convert the high-power idle energy replenishment mode of the target vehicle to the low-power idle energy replenishment mode, and change the control parameters of the target heat dissipation components to the low-power idle energy replenishment strategy.
[0070] The present application provides a control method for vehicle idle energy replenishment, which controls the fan and low-temperature circuit electronic water pump duty cycle when the vehicle is idle energy replenishment by detecting the vehicle charging power, ambient temperature, OBC & DC / DC inlet water temperature, air conditioning pressure, wind direction and wind speed signals, and takes away the heat of the condenser and low-temperature radiator and high-temperature radiator. When the heat dissipation demand cannot be met, the compressor speed is controlled to reduce the condenser heat, thereby reducing the wind temperature entering the low-temperature radiator, so as to avoid the vehicle DC / DC power limitation as much as possible and ensure the low-voltage electrical balance of the vehicle.
