Embodiments of the present application are described in detail below with reference to the accompanying drawings.
One or more embodiments of the present application provide a vehicle driving thermal management execution method, which is applied to a vehicle thermal management system.
Here, the execution modes of the vehicle thermal management system include a low power consumption operation mode and a non-low power consumption operation mode, and the thermal management system includes a thermal management component such as a motor-related component or a battery component, etc. that needs to be cooled down. For the above-mentioned thermal management system, the cooling mode of the motor related component or the battery component may be cooling by a fan or cooling by a cooling liquid circulation loop, which is not described herein.
As shown in fig. 1 and 2, in some embodiments, the vehicle driving thermal management execution method described herein includes:
s101, acquiring driving scene information of a vehicle, and acquiring speed information of the vehicle in response to determining that the current driving scene of the vehicle is a target lane, wherein the target lane is a traffic lane between a highway and a service area.
In the step S101, the driving scene information of the vehicle refers to the lane information of the current driving of the vehicle, the vehicle central control may acquire the vehicle position by means of navigation (such as GPS, beidou satellite positioning) or the like, and when the acquired vehicle position is located on the target lane, the vehicle central control determines that the vehicle needs to temporarily stop in the service area, and acquires the current vehicle speed information of the vehicle in this scene.
It should be noted that, because the vehicle position is switched from the expressway to the target lane, the vehicle speed is reduced compared with the expressway at the moment, but the vehicle heat management component heats up faster due to the influence of medium-high speed driving factors of the vehicle, and at the moment, if the low-power consumption operation of the heat management system is controlled in a trade, the heat management component is unstable in temperature control, and potential safety hazard is generated; therefore, it is necessary to perform the subsequent steps of the present application after the comprehensive determination is performed in combination with the vehicle speed information.
In addition, before the step S101, the vehicle center controller may acquire whether the vehicle position is located on the expressway, and perform the vehicle driving thermal management execution method described in the present application when the vehicle is driving on the target lane of the expressway. The target lane may be a highway-to-service ramp or other transition guide lane between the highway and the service area, which is only illustrated in this embodiment.
In some embodiments, in step S101, it includes:
s1011, determining a first estimated driving range of the vehicle according to the distance between the current position of the vehicle and the destination of the vehicle;
and S1012, acquiring driving scene information of the vehicle in response to the first predicted driving distance being greater than a second preset value.
In the above steps S1011 and S1012, the second preset value is exemplified to be 5km, the vehicle center controller obtains the current position and the destination information of the vehicle by navigation (e.g. GPS, beidou satellite positioning) and the like, then determines the first estimated driving range of the vehicle, compares the first estimated driving range with the second preset value, and when the first estimated driving range is greater than the second preset value (5 km) and the vehicle position is located on the target lane, determines that the vehicle owner may have a temporary parking intention, and then performs the subsequent thermal management execution method in combination with the driving scene information of the vehicle.
Further, in some embodiments, in step S101, it includes:
s1013, determining a second estimated driving distance of the vehicle according to the distance between the current position of the vehicle and the service area;
s1014, acquiring the temperature of the thermal management component in the thermal management system in response to the second predicted driving distance being smaller than the third preset value and the vehicle speed information being smaller than the first preset value.
In the step S1013 and the step S1014, after the vehicle central controller determines that the vehicle is located on the target lane, the second estimated driving distance may be determined by combining the current position of the vehicle with the distance between the vehicle and the service area, and in an exemplary embodiment, the third preset value may be 500m, and when the distance between the current position of the vehicle and the service area, that is, the second estimated driving distance is less than 500m, the vehicle speed information of the vehicle is acquired.
It should be noted that, in the present application, the first predicted driving distance should be greater than the second predicted driving distance, and the second preset value should be greater than the third preset value, so that the vehicle central control can more accurately determine the driving intention of the vehicle.
The vehicle driving thermal management execution method of the application further comprises the following steps:
step S102, in response to determining that the vehicle speed information is smaller than a first preset value, acquiring the temperature of a thermal management component in the thermal management system.
In the above steps, the first preset value is, for example, 70km/h, and when the detected vehicle speed information is less than 70km/h, since the vehicle has been switched from the expressway to the target lane and is traveling into the service area, the vehicle speed is not greatly increased any more, the temperature of the thermal management components of the vehicle is increased with the increase in traveling time, but the increase is controllable, and the temperature of the thermal management components of the thermal management system is acquired in this scenario.
Of course, the first preset value is only illustrated, and other values may be selected for the first preset value according to different driving factors such as the external environment temperature, the vehicle driving on a flat road, the uphill driving or the downhill driving, for example, the vehicle driving continuously on the target lane, at this time, the output power of the thermal management component is larger, the temperature rise is faster, and the first preset value is correspondingly reduced.
In the step S102, the thermal management component refers to an execution object of the vehicle thermal management system for cooling, including a motor-related component, a battery component, and the like, and the temperature of the thermal management component may be obtained by directly obtaining the temperature through a temperature sensor disposed on the corresponding thermal management component, or by determining the temperature of the corresponding thermal management component through the temperature of the cooling liquid flowing through the thermal management component.
In some embodiments, the vehicle driving thermal management execution method of the present application further includes:
and S103, in response to determining that the temperature of the thermal management component is less than or equal to a preset temperature value, sending an execution signal corresponding to the low-power-consumption operation mode to the thermal management system so as to enable the thermal management system to operate according to the low-power-consumption operation mode.
In step S103, the vehicle central controller may determine a preset temperature value of the thermal management unit capable of low power consumption operation according to an upper limit temperature value of the thermal management unit, the second predicted driving range and the vehicle speed information, where the upper limit temperature value of the thermal management unit refers to a limit temperature that can be reached by a motor related unit or a battery unit without affecting the service life and the working performance of the motor related unit or the battery unit, and after exceeding the upper limit temperature value, the service life of the thermal management unit is seriously affected, where the upper limit temperature value may be obtained by the attribute of the thermal management unit itself.
In some embodiments, the preset temperature value of the thermal management component is a value lower than an upper limit temperature value, and by way of example, when the vehicle is in a running state of a certain speed, the preset temperature value is obtained by subtracting the predicted temperature rise value of the thermal management component from the upper limit temperature value in the time, and the specific formula is as follows:
t=T-m;
wherein T is a preset temperature value, and T is an upper limit temperature value of the thermal management component; m is a constant.
In the above formula, the constant m is related to the estimated driving distance and the vehicle speed information of the vehicle, and since no congestion condition is involved in the target lane, the longer the estimated driving distance of the vehicle is, the larger the estimated temperature rise value in the driving time is, the larger the constant m is, and the smaller the preset temperature value of the thermal management component is; similarly, the faster the vehicle speed, the larger the predicted temperature increase value in the running time, the larger the constant m, and the smaller the preset temperature value of the thermal management member. In summary, the vehicle center control needs to determine the time for the thermal management component to rise from the preset temperature value to the upper limit temperature value in the following predicted driving mileage and vehicle speed of the vehicle, so that the temperature of the thermal management component is as low as possible to be less than or equal to the upper limit temperature value after the vehicle reaches the service area. The device can further optimize the output power consumption of the vehicle, reduce the redundant loss of the vehicle when the vehicle approaches to the service area, and further be beneficial to improving the endurance of the vehicle. Illustratively, m is 10 ℃.
It should be noted that, in some embodiments, the temperature of the thermal management component may be a plurality of temperatures of a plurality of different thermal management components, and when the plurality of temperatures of the plurality of different thermal management components are obtained, the highest temperature of the plurality of temperatures is obtained, so as to meet that the upper limit temperature value is not reached after the low power consumption operation is performed at the highest temperature of the thermal management component; when the temperature of the thermal management component is obtained by using the temperature of the cooling liquid in the liquid circulation loop, the temperature of the cooling liquid can be directly used as a reference, and generally, the temperature of the cooling liquid is slightly lower than the temperature of the thermal management component.
In some embodiments, in step S103, the thermal management system operates in a low power consumption operation mode, including the following two scenarios:
(1) Transmitting an execution signal corresponding to the low-power-consumption operation mode to a liquid circulation loop of the thermal management system so as to reduce the flow rate or cooling power of cooling liquid in the liquid circulation loop; and/or the number of the groups of groups,
(2) And sending an execution signal corresponding to the low-power-consumption operation mode to a cooling fan of the thermal management system so as to reduce the rotation speed of the cooling fan or switch off the cooling fan.
The foregoing describes two forms of low power operation of the thermal management system, and in some embodiments, the coolant in the fluid circulation loop cannot be empty, as needed to protect the relevant components, so the low power operation mode of the thermal management system includes the case of using the control water pump to minimize the flow rate of the coolant in the fluid circulation loop. The low power consumption operation mode includes a case where the cooling power of the coolant and the output power of the cooling fan are reduced to 20% of the original rated power.
In some embodiments, after step S103, further comprising:
s104, detecting the temperature of the thermal management component;
s105, in response to determining that the temperature of the thermal management component is less than the upper limit temperature value, maintaining a low power consumption operation mode of the thermal management system;
and S106, in response to determining that the temperature of the thermal management component is greater than or equal to the upper limit temperature value, sending a switching signal to the thermal management system so as to switch the low-power-consumption operation mode of the thermal management system into a non-low-power-consumption operation mode.
The steps are performed based on the fact that the thermal management system is operated with low power consumption, when the vehicle is in a driving state, the temperature of the thermal management component is continuously detected and obtained, and when the detected temperature of the thermal management component is smaller than an upper limit temperature value, the fact that the thermal management component of the vehicle is larger than a preset temperature value but not reaches the upper limit temperature value affecting the service life is proved, and at the moment, the low power consumption operation mode can be continuously maintained; when the detected temperature of the thermal management component is greater than or equal to the upper limit temperature value, it is proved that the thermal management component is too high in temperature and has reached a high temperature environment affecting the working life and the working performance, and therefore, the thermal management system needs to be switched to a non-low power consumption operation mode to cool the thermal management component as soon as possible.
The setting can further reduce the execution energy consumption of the thermal management, and meanwhile, different execution strategies are adopted for the thermal management system by utilizing the echelon setting scene, so that the intelligent and humanized work of the thermal management system can be ensured, and the judgment logic of the thermal management system is optimized.
It should be noted that, the non-low power consumption operation mode of the thermal management system refers to a state having higher output power than the low power consumption operation mode, that is, a state in which the flow rate or cooling power of the cooling liquid in the liquid circulation circuit is higher or the rotation rate of the cooling fan is faster.
In some embodiments, the non-low power mode of operation includes a plurality of different forms of thermal management modes of operation, and illustratively the non-low power mode of operation includes a first preset mode of operation having an output power consumption greater than an output power consumption of a second preset mode of operation.
The first preset operation mode corresponds to a thermal management cooling operation mode under full power and high power consumption, and in the state, the output power of a water pump of a liquid circulation loop in the thermal management system is maximum, and a cooling fan is started and rotates at a high speed; the second preset operation mode corresponds to a thermal management cooling operation mode under medium power and medium power consumption, and in this state, the output power of a water pump of a thermal circulation loop of the thermal management system is 50% of full power, and the fan is turned off.
The first preset operation mode and the second preset operation mode are only exemplified, and for different driving scenes, the first preset operation mode and the second preset operation mode can be adjusted, for example, the output power of a water pump of a liquid circulation loop in the thermal management system in the first preset operation mode is 50% of full power, and the cooling fan is started and rotates at a high speed; the output power of a water pump of a liquid circulation loop in the thermal management system is maintained at the lowest value, and a cooling fan is started and rotates at a high speed in a second preset operation mode; as long as a plurality of different output power consumption thermal management modes of operation are provided.
Through setting up the thermal management running mode of a plurality of different output power consumption, can be targeted optimize the adaptation to different driving scenes to reduce whole car output power consumption as far as under the prerequisite that satisfies the vehicle and travel, promote vehicle duration.
Based on the above description, in some embodiments, step S103 further includes:
s107, acquiring temperature information of the thermal management component and surrounding environment temperature information;
s108, in response to the fact that the temperature of the thermal management component is larger than or equal to the upper limit temperature value and the surrounding environment temperature information is larger than or equal to the fourth preset value, a switching signal is sent to the thermal management system so as to switch the low-power-consumption operation mode of the thermal management system into a first preset operation mode;
and S109, in response to the fact that the temperature of the thermal management component is larger than or equal to the upper limit temperature value and the ambient temperature information is smaller than the fourth preset value, a switching signal is sent to the thermal management system so as to switch the low-power-consumption operation mode of the thermal management system into a second preset operation mode.
In the above steps, the fourth preset value is exemplary, and when the temperature of the thermal management component is greater than or equal to the upper limit temperature value and the ambient temperature is greater than or equal to 5 ℃, the effect of the thermal management component through external air cooling is limited due to the higher ambient temperature, so that the thermal management component needs to be cooled in the first preset operation mode with higher power consumption of the thermal management system; when the temperature of the thermal management component is greater than or equal to the upper limit temperature value and the ambient temperature is less than 5 ℃, the thermal management system can cool through a second preset operation mode with lower power consumption because the ambient temperature is lower and the thermal management component is sufficiently cooled by natural air of the ambient environment. In a word, reduce the output power consumption of whole car thermal management system as far as possible under the prerequisite that guarantee that thermal management part temperature can drop down to lower than upper limit temperature value rapidly.
In summary, as shown in fig. 2, an exemplary method for performing thermal management for vehicle driving provided in the present application is as follows:
