[0061] See also Figure 1 , Figure 1 is a schematic diagram of an application environment according to an exemplary embodiment. Figure 1 As shown, the application environment may include a cabin-pilot fusion domain controller 10 and a cooling system 20 of the cabin-pilot fusion controller.
[0062] In an optional embodiment, the cabin-drive fusion domain controller 10 is used to integrate the functions of the vehicle driving domain (such as powertrain control, chassis control, etc.) and the cockpit domain (such as infotainment system, instrument panel display, etc.). The cabin-drive fusion domain controller 10 mainly includes an intelligent driving functional area and an intelligent cockpit functional area. The intelligent driving functional area has automatic emergency braking, lane keeping assist, automatic driving functions, etc., which are used to perform intelligent driving control of the vehicle. The intelligent cockpit functional area has an infotainment system, an instrument panel display, in-vehicle environment control, a human-computer interaction interface, etc., which are used to intelligently control the cabin-drive fusion domain on the vehicle.
[0063] In an optional embodiment, the heat dissipation system 20 is mainly used to dissipate heat from the cabin-pilot fusion domain controller 10 so that the cabin-pilot fusion domain controller 10 can operate continuously and stably.
[0064] In addition, it should be noted that Figure 1 What is shown is only one application environment of the heat dissipation method of the vehicle cabin-driving fusion domain controller provided by the present invention.
[0065] Figure 2 FIG. 1 is a structural diagram of a heat dissipation system of a cabin-driver fusion domain controller according to an exemplary embodiment. Figure 2 As shown, the heat dissipation system includes a control module, a heat dissipation water channel, a central partition, and a partition telescopic module.
[0066] The central partition is set in the heat dissipation water channel, and the central partition is used to divide the heat dissipation water channel into a first heat dissipation water channel and a second heat dissipation water channel, that is, to perform regional heat dissipation treatment on the vehicle's cabin-driver fusion domain controller. The first heat dissipation water channel is used to perform water cooling and heat dissipation treatment on the intelligent driving function area in the cabin-driver fusion domain controller; the second heat dissipation water channel is used to perform water cooling and heat dissipation treatment on the intelligent cockpit function area in the cabin-driver fusion domain controller.
[0067] The intelligent driving functional area includes the corresponding intelligent driving SOC (System on Chip) chip. The intelligent driving SOC chip generally inherits the CPU (Central Processing Unit), NPU (Neural Processing Unit), and some include GPU (Graphics Processing Unit). It mainly runs the Linux system and is used to process vision-based lane line recognition, human, vehicle, and sign recognition, etc. During vehicle driving, the intelligent driving functional area is generally required to continuously recognize forward lane lines, vehicles, and personnel, etc., generally maintaining a relatively constant computing power and energy consumption, and the heat generation is kept constant. Then, according to the intelligent driving SOC chip, the temperature area corresponding to the intelligent driving functional area is determined as a normal high temperature area.
[0068] The smart cockpit functional area includes the corresponding smart cockpit SOC chip, which is used in the cockpit system of smart cars. The chip can process various information from inside and outside the vehicle, including navigation, entertainment, vehicle status monitoring, etc., and present it to the driver through display screens, audio equipment and other devices. The smart cockpit functional area mainly has high requirements for the main frequency temporal response. Therefore, according to the smart cockpit SOC chip, the temperature area corresponding to the smart cockpit functional area is determined as the instantaneous high temperature area.
[0069] In the cabin-pilot fusion domain controller, the waterproof and anti-corrosion levels are required to be high, and a sealed shell is used for protection. A water cooling plate is built into the domain controller to dissipate heat for the high-heat SOC chips and components. Corresponding heat dissipation channels are set around the water cooling plate to absorb and dissipate the heat when the cabin-pilot fusion domain controller is running.
[0070] According to the high temperature zones corresponding to different functional areas, the heat dissipation water channels are divided into high heat capacity heat dissipation water channels and high flow rate heat dissipation water channels. Among them, the high heat capacity heat dissipation water channel is characterized by a large volume of the heat dissipation fluid medium in the adjacent heat dissipation area, which can absorb heat from the smart cockpit functional area corresponding to the instantaneous high temperature zone. Therefore, the high heat capacity heat dissipation water channel corresponds to the second heat dissipation water channel, which is used for water cooling of the smart cockpit functional area. The high flow rate heat dissipation water channel is characterized by a small volume of the heat dissipation fluid medium in the adjacent area, but a high water flow rate, which can continuously and effectively take away heat. Furthermore, the high flow rate heat dissipation water channel corresponds to the first heat dissipation water channel of the present application, which is used for water cooling of the smart driving functional area.
[0071] The first heat dissipation water channel and the second heat dissipation water channel are divided by a central partition, and a first movable baffle is provided at one end of the central partition at the water outlet of the heat dissipation water channel, and a second movable baffle is provided at one end of the central partition at the water inlet of the heat dissipation water channel. A first movable axis is provided between the first movable baffle and the central partition, and the first movable baffle can rotate along the first movable axis. A second movable axis is provided between the second movable baffle and the central partition, and the second movable baffle can rotate along the second movable axis.
[0072] The partition expansion module in the heat dissipation system includes a metal spring and a conductive beam. The metal spring includes a first metal spring, a second metal spring, a third metal spring and a fourth metal spring. The first metal spring and the third metal spring are arranged in the first heat dissipation water channel, and the second metal spring and the fourth metal spring are arranged in the second heat dissipation water channel.
[0073] The conductive beams include a first conductive beam, a second conductive beam, a third conductive beam and a fourth conductive beam. The first conductive beam is arranged on the first movable baffle, the second conductive beam is arranged on the fixed inner wall of the central partition, the third conductive beam is arranged on the third movable baffle, and the fourth conductive beam is also arranged on the fixed inner wall of the central partition.
[0074] The first metal spring and the second metal spring are arranged between the first conductive beam and the second conductive beam, that is, one end of the first metal spring is connected to the first conductive beam, and the other end is connected to the second conductive beam; similarly, one end of the second metal spring is connected to the second conductive beam, and the other end is connected to the second conductive beam. The third metal spring and the second metal spring are arranged between the third conductive beam and the fourth conductive beam, that is, one end of the third metal spring is connected to the third conductive beam, and the other end is connected to the fourth conductive beam; similarly, one end of the fourth metal spring is connected to the third conductive beam, and the other end is connected to the fourth conductive beam.
[0075] In a possible implementation, the control module of the cooling system is connected to the cabin-driving fusion domain controller, and the intelligent driving function area and the intelligent cockpit function area in the cockpit-driving fusion domain controller are respectively provided with a driving temperature detection unit and a cabin temperature detection unit. The driving temperature detection unit can obtain the driving operating temperature in real time and transmit the driving operating temperature to the control module of the cooling system; the cabin temperature detection unit can obtain the cabin operating temperature in real time and transmit the cabin operating temperature to the control module of the cooling system. The control module receives the driving operating temperature and the cabin operating temperature in real time.
[0076] When the control module obtains that the driving operating temperature and the cabin operating temperature have not changed, that is, the cabin operating temperature is at the initial temperature, at this time, the water outlet and water inlet of the first heat dissipation water channel are smaller, so that the flow rate of the first heat dissipation water channel can be faster, thereby improving the heat dissipation efficiency of the intelligent driving functional area.
[0077] Figure 3 is a structural diagram showing an initial position of a movable baffle according to an exemplary embodiment. Figure 3 As shown, when the control module detects that the cabin operating temperature is at the initial temperature, the first movable baffle and the second movable baffle both rotate downward and the rotation angles of the first movable baffle and the second movable baffle are the same, that is, the larger the opening, the faster the water flow speed, which can ensure that the water flow rate per unit time increases. This application does not limit the initial position angle of the first movable baffle and the second movable baffle, which can be determined according to actual conditions.
[0078] The control module is also connected to the partition telescopic module, and the control module is used to adjust the voltage of the conductive beam of the partition telescopic module. Specifically, when the control module receives that the cabin operating temperature is in the temperature rising area, it adjusts the voltage of the first conductive beam and the second conductive beam. The first conductive beam and the second conductive beam are both conductive devices, the first conductive beam is provided with a positive electrode, and the second conductive beam is provided with a negative electrode, which is not limited in this application.
[0079] The control module may adjust the voltage of the first conductive beam and the second conductive beam according to the difference between the driving operating temperature and the cabin operating temperature.
[0080] For example, the cabin operating temperature is T A , driving operating temperature is T B , the voltage of the first conductive beam is V A , the voltage of the second conductive beam is V B , λ1 is the initial T A -T B The variable coefficient of the difference matrix, ρ1 is the variable coefficient of the initial preset voltage difference, and a1 is the preset voltage difference. When the cabin operating temperature is in an upward state, T A -T B Among them, λ1, ρ1, and a1 are all pre-set parameters. According to the temperature difference, the voltage difference V that needs to be adjusted can be determined. A -V B .
[0081] Specifically, the voltage difference is determined by: V A -V B =λ1(T A -T B )+ρ1×a1. The control module also includes a configuration storage unit, which stores the combination configuration data of the voltage difference between the first conductive beam and the second conductive beam. For example, according to the formula, if the voltage difference needs to be adjusted to 50 volts, the V corresponding to the voltage difference of 50 volts can be found from the configuration storage unit. A and V B The control module is based on V A and V B The data is used to adjust the voltage of the first conductive beam and the second conductive beam.
[0082] In a possible implementation, the control module further includes an adjustable power supply. A and V B data, the control module will V A and V B The data is sent to the adjustable power supply. The adjustable power supply is based on the corresponding V A and VB The data is used to adjust the voltage of the first conductive beam and the second conductive beam, so that the first metal spring sheet and the second metal spring sheet are extended and retracted, thereby driving the first movable baffle to adjust its position.
[0083] In one possible implementation, according to V A and V B The difference, i.e., the voltage difference, can determine the first opening and closing angle θ1 corresponding to the first metal spring. Exemplarily, ρ2 is the variable coefficient of the initial preset angle value, a2 is the preset angle value, and λ2 is the variable coefficient of the tension on both sides of the first metal spring. Given ρ2, a2, and λ2, the control module determines the first opening and closing angle θ1 corresponding to the first metal spring based on the above data. The specific formula is: θ1=λ2(V A -V B )+ρ2×a2. This setting can make the cooling system more accurately control the water flow speed and improve the cooling effect of the cooling system.
[0084] Similarly, the control module can also adjust the voltage of the third conductive beam and the fourth conductive beam according to the difference between the driving operating temperature and the cabin operating temperature. And the voltage adjustment method and data of the third conductive beam and the fourth conductive beam are the same as those of the first conductive beam and the second conductive beam. Specifically, the voltage of the third conductive beam is V C , the voltage of the fourth conductive beam is V D The control module can determine the voltage difference V that needs to be adjusted based on the temperature difference. C -V D =λ1(T A -T B )+ρ1×a1.
[0085] After determining V C -V D After that, the control module will C -V D , determine the second opening and closing angle θ2=λ2(V D -V D )+ρ2×a2. At this time, the flow rates of the water inlet and outlet of the heat dissipation water channel of the cabin-drive fusion domain controller can be adjusted according to the temperature, thereby improving the heat dissipation efficiency and reducing the device cost.
[0086] like Figure 4 As shown, Figure 4 is a structural diagram showing a movable baffle adjustment position according to an exemplary embodiment. When the cabin operating temperature is in an upward state, the control module rotates the first movable baffle and the second movable baffle upward to the position where the first movable baffle and the second movable baffle are in a downward position according to the driving operating temperature and the cabin operating temperature. Figure 4At this time, the outlet of the second heat dissipation channel is larger than the outlet of the first heat dissipation channel, and the inlet of the second heat dissipation channel is also larger than the inlet of the first heat dissipation channel. The present application does not limit the adjustment angles of the first movable baffle and the second movable baffle.
[0087] In a possible implementation, the heat dissipation system further includes a flow rate sensing unit, which includes a first flow rate sensor and a second flow rate sensor. The first flow rate sensor is arranged at the water inlet of the first heat dissipation water channel, and the second flow rate sensor is arranged at the water outlet of the first heat dissipation water channel.
[0088] After the control module performs voltage adjustment on the third conductive beam and the fourth conductive beam, a flow rate monitoring instruction is sent to the first flow rate sensor and the second flow rate sensor.
[0089] After receiving the flow rate monitoring instruction, the first flow rate sensor immediately monitors the water flow rate of the water inlet of the first heat dissipation water channel, obtains the input water flow, and transmits the input flow rate to the control module. The control module receives the input flow rate, analyzes the input flow rate, and obtains a first flow rate analysis result; when the first flow rate analysis result indicates that the input flow rate meets the preset input flow rate, it is determined that the position of the second movable baffle has been adjusted to the first preset position.
[0090] When the first flow rate analysis result indicates that the input flow rate does not meet the preset input flow rate, that is, the position of the second movable baffle is not adjusted to the first preset position, the control module restores the second movable baffle to the initial position, reacquires the cabin operating temperature and the driving operating temperature, adjusts the voltage of the third conductive beam and the fourth conductive beam, and then drives the second movable baffle to adjust the position. Further, the control module sends a flow rate monitoring instruction again and instructs the first flow rate sensor to perform analysis and judgment processing until the input flow rate meets the preset input flow rate.
[0091] After receiving the flow rate monitoring instruction, the second flow rate sensor immediately monitors the water flow rate of the water outlet of the first heat dissipation water channel, obtains the output flow rate, and transmits the output flow rate to the control module. The control module receives the output flow rate, analyzes the output flow rate, and obtains a second flow rate analysis result. When the second flow rate analysis result indicates that the output flow rate meets the preset output flow rate, it is determined that the position of the first movable baffle is adjusted to the second preset position.
[0092] Accordingly, when the second flow rate analysis result indicates that the output flow rate does not meet the preset output flow rate, that is, the first movable baffle is not adjusted to the second preset position, the control module restores the first movable baffle to the initial position, and adjusts the voltage of the first conductive module and the second conductive module according to the re-acquired cabin operating temperature and driving operating temperature, thereby driving the second movable baffle to adjust the position. Further, the control module sends a flow rate monitoring instruction again, and instructs the second flow rate sensor to perform analysis and judgment processing until the output flow rate meets the preset output flow rate.
[0093] In a possible implementation, the heat dissipation system further includes a temperature sensing unit; the temperature sensing unit includes a first temperature sensor and a second temperature sensor. The first temperature sensor is disposed at the water inlet of the first heat dissipation water channel, and the second temperature sensor is disposed at the water outlet of the first heat dissipation water channel.
[0094] After the control module adjusts the first movable baffle and the second movable baffle, it instructs the first temperature sensor to monitor the water temperature of the water inlet of the first heat dissipation water channel to obtain the input water flow temperature, and transmits the input water flow temperature to the control module; the control module receives the input water flow temperature, analyzes the input water flow temperature, and obtains a first temperature analysis result; when the first temperature analysis result indicates that the input water flow temperature meets the first preset temperature range, the position of the second movable baffle is determined to be adjusted to the first preset position.
[0095] The control module also instructs the second temperature sensor to monitor the water temperature of the water outlet of the second heat dissipation water channel, obtain the output water flow temperature, and transmit the output water flow temperature to the control module. The control module receives the output water flow temperature, analyzes the output water flow temperature, and obtains a second temperature analysis result; when the second temperature analysis result indicates that the output water flow temperature meets the second preset temperature range, it is determined that the position of the first movable baffle has been adjusted to the second preset position. At this time, it indicates that the water flow speed of the first heat dissipation water channel is reduced, while the water flow speed of the second heat dissipation water channel is increased. After the operating power consumption of the smart cockpit functional area is reduced, the control module controls the first movable baffle and the second movable baffle to return to their initial positions.
[0096] In another possible implementation, when the first temperature analysis result indicates that the input water flow temperature does not meet the preset temperature range, the control module controls the second movable baffle to return to the initial position. Further, the control module re-acquires the cabin operating temperature and the driving operating temperature, adjusts the voltage of the third conductive beam and the fourth conductive beam, and then drives the second movable baffle to adjust the position. Then, the first temperature sensor re-acquires the input water flow temperature of the water inlet of the first heat dissipation water channel for analysis and judgment. When the first temperature analysis result indicates that the input water flow temperature meets the preset temperature range, it is determined that the second movable baffle has been adjusted to the first preset position.
[0097] Accordingly, when the second temperature analysis result indicates that the output water flow temperature does not meet the preset temperature range, the control module controls the first movable baffle to return to the initial position. Further, the control module re-adjusts the voltage of the first conductive beam and the second conductive beam according to the cabin operating temperature and the driving operating temperature, thereby driving the first movable baffle to adjust the position. After the adjustment, the second temperature sensor re-acquires the output water flow temperature of the outlet of the first heat dissipation water channel for analysis and judgment. When the first temperature analysis result indicates that the output water flow temperature meets the preset temperature range, it is determined that the first movable baffle has been adjusted to the second preset position.
[0098] In a possible implementation, the control module can simultaneously instruct the temperature sensing unit and the flow rate sensing unit to monitor the first heat dissipation water channel, and when the flow rate analysis results and the temperature analysis results meet preset conditions, indicate that the first movable baffle and the second movable baffle are uniformly adjusted to a preset position.
[0099] The embodiments of this specification also provide a method for heat dissipation of a vehicle cabin-driving fusion domain controller, which is implemented using the heat dissipation system in the above embodiments.
[0100] Figure 5 FIG. 1 is a flow chart showing a method for cooling a cabin-pilot fusion domain controller according to an exemplary embodiment. Figure 5 As shown, the following steps are included:
[0101] In step S501, the heat dissipation water channel is segmented to obtain a first heat dissipation water channel and a second heat dissipation water channel.
[0102] In the embodiment of this specification, the heat dissipation water channel corresponding to the cabin-driver fusion domain controller is divided into a first heat dissipation water channel and a second heat dissipation water channel according to the central partition; wherein the first heat dissipation water channel is used to perform water cooling and heat dissipation treatment on the intelligent driving functional area in the cabin-driver fusion domain controller; and the second heat dissipation water channel is used to perform water cooling and heat dissipation treatment on the intelligent cockpit functional area in the cabin-driver fusion domain controller. The heat consumed by the intelligent driving functional area and the intelligent cockpit functional area during operation is different, and thus, performing heat dissipation in different regions can meet the heat dissipation requirements of different functional areas and improve the heat dissipation efficiency of each controller.
[0103] In step S503, the cabin operating temperature of the smart cabin functional area is obtained.
[0104] In the embodiment of this specification, the control module of the cooling system is connected to the intelligent cabin-driving fusion domain controller, and the control module is used to obtain the cabin operating temperature and the driving operating temperature, and monitor and process the cabin operating temperature.
[0105] In step S505, when the cabin operating temperature is rising, the voltage of the first conductive beam and the second conductive beam is adjusted to allow the metal spring to expand and contract, thereby driving the first movable baffle to adjust its position.
[0106] In one possible implementation, when the control module monitors that the cabin operating temperature is rising, the control module determines the voltage difference information between the first conductive beam and the second conductive beam, and the voltage difference information between the third conductive beam and the fourth conductive beam based on the temperature difference between the currently acquired cabin operating temperature and the driving operating temperature, wherein the two voltage difference information are the same.
[0107] According to the voltage difference information, the control module can control the adjustable power supply to adjust the mechanical energy voltage between each conductive beam, so that each metal spring can be adjusted to expand and contract, thereby driving the movable baffle to adjust from the initial position to the corresponding position, so that the water flow speed of the second cooling water channel becomes faster, allowing the smart cockpit functional area to dissipate heat quickly.
[0108] In a possible implementation, after adjusting the movable baffle, the control module can control the flow rate sensor unit provided in the heat dissipation water channel to monitor the flow rates of the water inlet and the water outlet of the first heat dissipation water channel, and obtain the input flow rate and the output flow rate respectively, and then transmit the input flow rate and the output flow rate to the control module.
[0109] After receiving the input flow rate and the output flow rate, the control module performs flow rate analysis on the input flow rate and the output flow rate respectively to obtain a first flow rate analysis result and a second flow rate analysis result.
[0110] The control module determines that the position of the second movable baffle is adjusted to the first preset position when the first flow rate analysis result indicates that the input flow rate meets the preset input flow rate; the control module determines that the position of the first movable baffle is adjusted to the second preset position when the second flow rate analysis result indicates that the output flow rate meets the preset output flow rate. After the flow rate sensing unit adjusts the position of the movable baffle, the flow rate is monitored to check whether the movable baffle is adjusted to the preset position, thereby improving the accuracy of the movable baffle adjustment and further improving the heat dissipation efficiency of the heat dissipation system.
