Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention can be embodied in many different forms than those herein described and it will be apparent to those skilled in the art that many changes can be made in this invention without departing from the spirit thereof and the scope of the invention is therefore not to be limited to the specific embodiments disclosed herein.
The vehicle referred to herein may be any vehicle having electronics, such as a hybrid vehicle, a pure electric vehicle, and autonomous driving, among others. The autonomous vehicle here may include a vehicle having a driving assist function, an advanced driving assist function. The following will be explained taking an autonomous vehicle as an example.
Fig. 1 is a schematic structural diagram of a cooling system for a vehicle according to one example of the present application. As shown, the cooling system includes a plurality of cooling circuits. By way of example and not limitation, the cooling system includes a first cooling circuit 10, a second cooling circuit 20, a third cooling circuit 30, and a fourth cooling circuit 40, and the number of specific circuits may be greater or less. A cooling liquid (not shown) may flow in the circuit to cool the object to be cooled during circulation. The cooling fluid may be water or other fluid capable of achieving cooling. The cooling system may further comprise a sensor provided for each cooling circuit for sensing a characteristic quantity of the cooling liquid in each cooling circuit. By way of example and not limitation, in this example, the cooling system includes a first sensor 101, a second sensor 201, a third sensor 301, and a fourth sensor 401. The first sensor 101 is disposed in the first cooling circuit 10, the second sensor 201 is disposed in the second cooling circuit 20, the third sensor 301 is disposed in the third cooling circuit 30, and the fourth sensor 401 is disposed in the fourth cooling circuit 40, for detecting the characteristic amount of the coolant in the cooling circuit in which it is disposed and outputting the sensing information, respectively. The characteristic quantities refer to parameters capable of characterizing the cooling operation state of the cooling liquid, such as the temperature, the pressure, the flow rate or any combination thereof of the cooling liquid, and other characteristic quantities not listed here but capable of characterizing the cooling state of the cooling liquid are also within the scope of the present application. In some examples, the first sensor 101, the second sensor 201, the third sensor 301, and the fourth sensor 401 may be temperature sensors, or pressure sensors, or flow sensors. In still other examples, each of the first sensor 101, the second sensor 201, the third sensor 301, and the fourth sensor 401 may include sensors for sensing any two or three of temperature, pressure, flow, etc., e.g., the first sensor 101 may include a pressure sensor, a temperature sensor, and/or a flow sensor, etc., and the like applies to the second sensor 201, the third sensor 301, and the fourth sensor 401. However, in still other examples, the first sensor 101, the second sensor 201, the third sensor 301, and the fourth sensor 401 may be a composite sensor capable of sensing any two or three of temperature, pressure, and flow rate simultaneously.
The cooling system may also comprise regulating elements arranged in the circuits, for example one regulating element in each cooling circuit, for regulating the flow of cooling liquid in the cooling circuit in which it is located. By way of example and without limitation, a first conditioning element 103, a second conditioning element 203, a third conditioning element 303, a fourth conditioning element 403 are provided in the first cooling circuit 10, the second cooling circuit 20, the third cooling circuit 30 and the fourth cooling circuit 40, respectively, to regulate the flow of cooling liquid in the respective circuits by means of the respective conditioning elements.
Still referring to fig. 1, the cooling system of the illustrated example further includes a controller 50 that receives sensed information transmitted by each of the sensors. The controller 50 is configured to receive the sensed information transmitted by each of the sensors and is configured to control one or more actions in the adjustment element in accordance with each of the sensed information. Referring to fig. 1, the controller 50 receives sensing information from the first sensor 101, the second sensor 201, the third sensor 301, and the fourth sensor 401, and determines whether to control the operation of the adjustment element in the circuit corresponding to the sensor according to the received sensing information. The first 103, second 203, third 303, and fourth 403 adjustment elements are configured to be actuated in accordance with a control action of the controller 50, e.g., upon receipt of a control signal from the controller 50, will be actuated in accordance with the control signal. By way of example, the action may be to shut off, adjust the flow rate, or adjust the flow rate down, etc.
In the cooling system for a vehicle shown in fig. 1, a sensor is provided for each cooling circuit. The sensor will sense a characteristic quantity of the cooling liquid in the circuit in which it is located. The controller 50 receives the sensed characteristic from each sensor, determines the cooling status of each circuit based thereon, and adjusts the distribution of the cooling fluid in each circuit. For example, the controller 50 receives the sensed information from the first sensor 101, the second sensor 201, the third sensor 301 and the fourth sensor 401, determines that the temperature of the cooling fluid in the first cooling circuit 10 is low, the temperature of the cooling fluid in the second cooling circuit 20 is moderate or desirable, and the temperature in the third cooling circuit 30 and the fourth cooling circuit 40 is relatively high, which indicates that the first cooling circuit 10 may have cooled the electronic unit that it is cooling to the desired effect, and reduces the amount of cooling fluid to reduce the cooling effect, and the temperature in the third cooling circuit 30 and the fourth cooling circuit 40 is relatively high to indicate that the temperature of the cooled electronic unit is relatively high, and further cooling can be performed by increasing the amount of cooling fluid, for example. Controller 50 generates and sends signals to the respective actuators that cause first actuator 103 to decrease the flow, and third actuator 303 and fourth actuator 403 to each decrease the flow. In this way, the cooling liquid is distributed according to the working condition of the whole system, and a more effective cooling effect is achieved under the condition of not changing the total amount of the cooling liquid. Furthermore, in contrast to the conventional cooling manner of a cooling system for a vehicle that focuses only on the temperature of an object to be cooled (e.g., an electronic component, an electronic unit, an electronic device, an electronic system, etc.), the cooling system for a vehicle illustrated by fig. 1 judges the cooling effect on the electronic unit or device according to the characteristic amount of the coolant in the cooling circuit and adjusts the distribution of the coolant in each circuit accordingly. The distribution of the cooling liquid in each loop is adjusted in real time through the feedback of the cooling system, so that the control of the whole cooling system is not easily influenced by external components and factors, and the control robustness is better. The signal transmission between the controller 50 and each sensor and each flow rate adjustment element may be through a cable connection, or may be through communication in a different cable-through manner, such as wireless communication. In the example shown in fig. 1, the controller 50 and the sensors and the flow regulating elements can be directly communicated or directly connected for data transmission, and the connection relationship is not shown and is only for simplicity of illustration.
In some examples, the cooling system shown in FIG. 1 also includes a storage tank 60 for storing cooling fluid. The storage tank communicates with each cooling circuit for the coolant to flow from the storage tank into each cooling circuit and then back again, and so forth. The storage box 60 may be provided at a suitable position in the vehicle. According to these examples of the present application, the storage tank 60 is provided in the boot region of the vehicle, in which case it may be more convenient for addition of coolant, maintenance of the storage tank 60, and the like. Optionally, a pump 70 may be provided between storage tank 60 and each cooling circuit. The pump 70 may help to accelerate the flow of the cooling fluid.
In still other examples, the cooling system shown in FIG. 1 further includes a heat exchanging portion 80. The heat exchange portion includes a heat exchange body configured to accommodate a plurality of cooling circuits therethrough to effect heat exchange. Fig. 2 is a schematic illustration of the heat exchanging portion 80 provided in the vehicle, and it should be noted that only the relevant portions thereof are illustrated to more clearly show the configuration of the heat exchanging portion 80. As shown, the body 802 of the heat exchange portion 80 is provided at a bottom 1110 of a vehicle (not shown), for example, a portion of the vehicle bottom 1110 for providing the heat exchange portion 80 is recessed toward a roof direction to form a recessed portion for placing the body 802 of the heat exchange portion, for example, the body 802 is fixed to the vehicle bottom 1110. The heat exchange portion further includes a spoiler 801. The spoiler 801 is configured to form a wind tunnel 1112 with the vehicle body bottom 1110, for example, with the recessed portion, and the wind inlet 1112a of the wind tunnel 1112 is smaller than the wind outlet 1112 b. The air inlet 1112a may be smaller than the air outlet 1112b in terms of the cross-sectional area of the air inlet smaller than the cross-sectional area of the air outlet, and the cross-section is a cross-section perpendicular to the bottom of the vehicle body. As an example, the end of the spoiler 801 at the air inlet and/or the air outlet may be bent towards the ground, respectively, but this is not essential, e.g. only the air outlet is bent, which is more favorable for the wind to be carried away through the wind tunnel. Alternatively, neither end portion may be bent. The spoiler 801 may be disposed on the body 802. It should be noted that although the heat exchanging portion 80 is provided at the bottom of the vehicle, other portions of the vehicle body may be provided as well, such as the lower portion on the vehicle body side, for example.
According to some examples of the application, the adjusting element referred to herein is a throttle valve. The throttle valve operates under the control of the controller 50.
According to still further examples of the present application, the sensor provided in each circuit for sensing the characteristic amount may include a pressure sensor, a temperature sensor, and a flow sensor. In other words, the sensors disposed in each loop are a sensor group of one or more sensors. Alternatively, however, a compound sensor may be selected that outputs pressure, temperature, and flow sensing information simultaneously.
According to some examples of the application, the controller 50 is configured to compare the sensed information received from each cooling circuit with a preset sensing threshold, e.g., to generate a control signal to control operation of each conditioning element.
Fig. 3 is a flowchart of a control process of the controller 50 when used in the cooling system shown in fig. 1. The process shown in fig. 3 will now be described in conjunction with fig. 1. The first, second, third and fourth cooling circuits 10, 20, 30 and 40 are used to cool the first, second, third and fourth electronic units 107, 207, 307 and 407, respectively. By way of example and not limitation, the first electronic unit 107 is a calculation and graphics processing unit, the second electronic unit 207 is a vehicle control information processing unit, the third electronic unit 307 is an image acquisition component such as a camera and a data acquisition unit such as a radar, and the fourth electronic unit 407 is a blind zone sensor unit. Depending on the nature of the electronic units, the degree of cooling they need to achieve may vary, based on which a coolant temperature threshold is set for each cooling circuit. For example, the temperature threshold of the coolant in the first cooling circuit 10 is T1, the temperature threshold of the second cooling circuit 20 is T2, the temperature threshold of the third cooling circuit 30 is T3, and the temperature threshold of the fourth cooling circuit 40 is T4. Reaching a set threshold indicates that cooling of the electronic unit is within a desired effect, and detecting or sensing a temperature of the cooling fluid above the threshold indicates that the temperature of the electronic unit being cooled is still high. Referring to fig. 3, the controller 50 receives (step S300) the respective sensing from the first sensor 101, the second sensor 201, the third sensor 301, and the fourth sensor 401Temperature value T of coolant in self-loop1current、T2current、T3currentAnd T4current. The controller 50 further compares the received temperature values with a threshold value for the loop (step S302), specifically, T1currentComparing T with T12currentComparing T with T23currentComparing T3 with T4currentCompared to T4. Based on the comparison, the controller 50 determines (step S304) how to adjust the flow of coolant in each circuit. For example, at T1current≥T1,T2current≤T2,T3currentT3, and T4currentWithout a significant difference from T4, controller 50 would generate a control signal to first regulating element 103 requesting it to adjust so that the flow rate increases, while generating control signals to second regulating element 203 and third regulating element 303 so that it adjusts the flow rate down the circuit in which it is located. In a further example, the controller 50 may make more precise control based on the difference between the threshold value and the actual value.
It should be noted that the control process of the controller 50 is described in connection with the example shown in fig. 1, but in reality, the controller 50 can also implement the process as described above when implemented as a control element alone, regardless of the circuits, the number and types of sensors, etc. listed herein.
The present application further provides a method of managing a cooling system of a vehicle. Fig. 4 is a flow chart of the method. As shown in the drawing, in step S1000, a plurality of sensors for sensing a characteristic amount of the coolant in the cooling circuit and outputting sensed information are provided for each cooling circuit in the cooling system of the vehicle. For example, a sensor for sensing the characteristic quantity is provided in each cooling circuit. For example, the respective sensors shown in fig. 1 are provided. In step S1002, the flow of the coolant in the corresponding cooling circuit is controlled in accordance with the sensing information output from each sensor. As an example, controlling the flow of cooling liquid in the respective cooling circuit comprises generating a control signal and transmitting the control signal to the regulating element of the respective circuit to be actuated in dependence on said control signal. Regarding step S1002 and its related implementation, reference may be made to the control procedure of the controller, for example, as described above in connection with fig. 1 and 3.
The present application also provides a control system for a vehicle cooling system, a block diagram of which is illustrated in fig. 5. As shown, the control system for a cooling system of a vehicle according to this example includes a plurality of sensors 400 and a controller 600. The sensors 400 are respectively provided in the cooling circuits of the vehicle for sensing characteristic amounts of the coolant flowing through the cooling circuits and outputting sensing information. The characteristic quantities are already stated above and are not described again. Illustratively, the sensor 400 may be implemented as the first sensor 101, the second sensor 201, the third sensor 301, and the fourth sensor 401 described above in connection with fig. 1, although the number is not limited thereto. The above description of the first sensor 101, the second sensor 201, the third sensor 301 and the fourth sensor 401 applies to the sensor 400 in this example. The controller 600 receives sensed information from the plurality of sensors 400, and the controller 600 is further configured to control the flow in each cooling circuit according to the sensed information from the sensors.
According to some examples of the present application, further comprising regulating elements (not shown) disposed in each cooling circuit, the regulating elements receiving control from the controller 600 to act, thereby regulating the flow of the cooling liquid in the cooling circuit. According to some examples of the present application, the adjustment elements may be implemented as the first adjustment element 103, the second adjustment element 203, the third adjustment element 303, and the fourth adjustment element 403 described above in connection with fig. 1. The number is not limited thereto. The above description of the first adjusting element 103, the second adjusting element 203, the third adjusting element 303 and the fourth adjusting element 403 applies to the adjusting elements in this example. By way of non-limiting example, each adjusting element may be a throttle valve in the present application. The controller 600 may be implemented as the controller 50 as described above in connection with fig. 1, 3.
The present application further provides a vehicle including a cooling system and a heat exchange portion. Fig. 6 is a schematic illustration of a vehicle according to an example of the present application. Fig. 7 is a schematic view of a cooling system and a portion of a heat exchanging portion provided in the vehicle, and it is helpful to understand the vehicle shown in fig. 6 in conjunction with fig. 7. In this example, the vehicle is an autonomous vehicle.
As shown in fig. 7, the cooling system includes a plurality of cooling circuits 700 for circulating a coolant in each of the cooling circuits to cool an object to be cooled provided on the vehicle during circulation. In the present example, the objects to be cooled in the autonomous vehicle include electronic units 707 (see fig. 6, e.g., a sensor such as a radar provided on the roof and a processor thereof, etc.), 708 (see fig. 6), 709 (not illustrated in fig. 6), and 710 (not illustrated in fig. 6) provided at the front end portion, the roof, and the rear portion of the vehicle, respectively. The cooling system further includes a plurality of sensors 720 provided in each cooling circuit, each sensor being configured to sense a characteristic amount of the cooling liquid in the circuit in which it is provided and output sensed information, and adjustment elements 722 provided in each circuit, each of the adjustment elements 722 being controlled to adjust the flow of the cooling liquid in the circuit in which it is provided. The cooling system also includes a controller 725 that receives sensed information output by each of the sensors and controls one or more actions in the adjustment element 722 based on the sensed information of each sensor. Each of the adjustment elements 722 acts upon a control signal received from the controller 725. The cooling system of the vehicle further includes a storage tank (not shown) for storing the coolant and a pump (not shown) disposed between the storage tank and the cooling circuit.
A body 726 of the heat exchange portion is illustrated in fig. 7, the body being configured to accommodate the plurality of circuits. Referring to fig. 6, in the vehicle, the heat exchange portion is formed at the bottom of the vehicle body. For example, a portion of the underbody for disposing the heat exchange portion body is configured to be recessed toward the roof, thereby forming a recessed portion in which the heat exchange portion body is placed, and the heat exchange portion body is fixed in the recessed portion. The heat exchange portion further includes a spoiler 727. The spoiler 727 is configured to match the body and form an air duct with an air inlet smaller than an air outlet with a bottom of the vehicle, in which the body of the heat exchange portion is located. For example, the spoiler 727 is configured to form an air duct having an air inlet smaller than an air outlet with a concave portion for accommodating the body. The heat exchanging part may refer to the heat exchanging part 80 described in conjunction with fig. 2. Alternatively, the heat exchange portion may be provided at other portions of the vehicle body, such as a vehicle body side lower portion and the like.
Referring to fig. 6 and 7, the storage tank, the pump, the sensors, the adjustment elements, and the controller of the heat exchange system are disposed in the trunk part 740 of the vehicle, which facilitates inspection and replacement, and avoids the need for separate maintenance in a distributed design because they are disposed in the trunk part. According to the present application, a thermal shield 730 is also included, the thermal shield 730 being used to isolate components of the cooling system from other components of the vehicle in the trunk area of the vehicle so that heat generated by electronic components such as sensors, controllers, etc. in the cooling system does not affect the vehicle.
In the example in connection with fig. 6 and 7, the plurality of sensors 720 is implemented, for example, as the plurality of sensors shown in fig. 1, and the arrangement and function of the sensors described in connection with fig. 1 are applicable to the sensors described in this example. The control elements 722 provided in the individual circuits are realized, for example, as control elements shown in fig. 1, the arrangement and function of the control elements described in connection with fig. 1 being applicable to the control elements described in this example. The controller 725 may be implemented as the controller 50 illustrated in fig. 1.
In the example combining fig. 6 and fig. 7, the operation of the cooling system is similar to the above examples of fig. 1, fig. 2, and fig. 3, and thus will not be described again. The coolant entering each circuit is uniformly distributed by the controller 725 so that cooling of the various electronic units is more efficient without changing the total amount of coolant. Furthermore, by providing a sensor for each circuit, sensing its characteristic quantity such as temperature, pressure, flow rate, etc., the cooling state of each cooling circuit can be known in real time. The interaction of the sensors, the controller and the flow control element thus ensures that the individual cooling circuits of the cooling system according to the present application or of the cooling system of a vehicle no longer operate individually, but rather are managed in an integrated manner, wherein the operating state of the coolant in the circuits is known in real time and the flow of the coolant in the circuits is adjusted in time in accordance therewith, so that a systematic and efficient cooling is achieved. In addition to this, as described above, in the vehicle, most of the components of the cooling system are managed by being disposed in the same portion of the vehicle (e.g., the trunk portion) except for the circuit wiring, so that the entire cooling system is more compact and easy to maintain.
The cooling system for a vehicle shown in fig. 1 is applicable to the vehicle shown in fig. 6. Similarly, the control system for the cooling system of the vehicle described above may be applied to the vehicle shown in fig. 6 and/or the cooling system shown in fig. 7. The method of managing a cooling system of vehicle zero described above may also be applied to the vehicle shown in fig. 6.
In addition, in all the above examples of the present application, a filtering unit may be further included in the cooling circuit, for example, at a position where the coolant flows back to the storage tank, in other words, after passing through the filtering unit, the coolant flows back to the storage tank. The cooling liquid filtered by the filtering unit removes redundant impurities, and is beneficial to improving the cooling effect.
The cooling system of the present application, and a vehicle and the like using the cooling system have been described above by way of example only. Although only a few embodiments of the present invention have been described in detail, those skilled in the art will appreciate that the present invention may be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and various modifications and substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
