No. 16/421,123, filed on May 23, 2019, which claims priority to Korean Patent Application No. 10-2018-0164120, filed in the Korean Intellectual Property Office on Dec. 18, 2018, which application is hereby incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     Embodiments of the present disclosure relate to an integrated controller, a vehicle including the same and a method of controlling the vehicle. 
     BACKGROUND 
     In general, a vehicle is transport means that runs on a road or a track to transport humans or objects to desired places. The vehicle moves by one or more wheels generally installed in the vehicle body. Examples of the vehicle include a three-wheeled vehicle, a four-wheeled vehicle, a two-wheeled vehicle such as a motorcycle, construction equipment, a bicycle, and a train running on a track. 
     Recently, studies into vehicles with Advanced Driver Assist System (ADAS) for actively providing information about vehicle states, a driver&#39;s states, and surrounding environments in order to reduce the driver&#39;s load and improve convenience are actively conducted. 
     As examples of ADAS mounted on vehicles, there are forward collision avoidance (FCA) system, autonomous emergency brake (AEB) system, and driver attention warning (DAW) system. The systems are collision avoidance and warning systems for determining the risk of collision with an object when vehicles are driven and performing emergency braking when the risk of collision with the object is determined. 
     In particular, an integrated controller of ADAS is being developed in which a high-performance application processor (AP) or field-programmable gate array (FPGA) chips are added to typical electronic units to apply sensor fusion and deep-running image recognition technology by installing various sensors for operating the ADAS. 
     However, the integrated controller with various chips generates heat upon operation. Therefore, studies for minimizing heat generation and securing effective heat dissipation performance are underway.

     The user interface  129  may be provided as a touch screen in which a touch panel and a display panel are integrated to perform both an input function and a display function. Also, the user interface  129  may be provided as a display panel to perform a display function. Accordingly, the user may make a touch input on the touch screen to select a desired function from among selectable functions displayed on the user interface  129 . 
     An air conditioner  131  may be installed in the center fascia  124 . The air conditioner  131  may adjust the inside temperature, humidity, air cleanliness, and air flow of the vehicle  100  to maintain the inside of the vehicle  100  pleasant. The air conditioner  131  may include at least one vent  131   a  installed in the center fascia  124  on an outer portion of the dashboard  122  and discharging air. In addition to the air conditioner  131 , the center fascia  124  may further include an air conditioning switch  131   b , such as a button or a dial, to enable the user to operate the air conditioner  131 . Accordingly, the user such as a driver may control the air conditioner  131  by using the button disposed on the center fascia  124 . Herein, the term driver is intended to include any individual in the vehicle, whether or not the individual is actually operating the vehicle. 
     The vehicle  100  may include various electronic devices in an inner space of the dashboard  122 , that is, behind the center fascia  124  in which the vent  131   a  of the air conditioner  131  is positioned.  FIG.  2    is a block diagram for describing a positional relationship between some components of the air conditioner  131  and an integrated controller  300  with an ADAS. 
     However, in the inner space of the dashboard  122  of the vehicle  100  illustrated in  FIG.  2   , other electronic devices may be further installed in addition to the air conditioner  131  and the integrated controller  300 . For example, the integrated controller  300  may further include an additional air conditioning duct in the inner space of the dashboard  122  by branching an air conditioning duct connected to a center console installed between a driver&#39;s seat and a passenger&#39;s seat in the air conditioner  131  and coupling the branched air conditioning duct to the upper end of the integrated controller  300 . 
     Particularly, as illustrated in  FIG.  2   , the air conditioner  131  and the integrated controller  300  may be installed in the inner space of the dashboard  122 . In  FIG.  2   , components for hardwarily operating the air conditioner  131  are illustrated. In  FIG.  3   , components of an air conditioning control unit  132  for softwarily operating the air conditioner  131  are illustrated in more detail. In  FIG.  4   , components constructing the integrated controller  300  are illustrated. 
     First, as illustrated in  FIG.  2   , the air conditioner  131  may include an evaporator/heater  138  for discharging air circulating to the vent  131   a  provided in the center fascia  124 , and include a driver  139  that generates wind before the evaporator/heater  138  operates. 
     The driver  139  may include a fan  136  rotating by a motor  136   a , and may generate wind when the fan  136  is driven. 
     The generated wind may be provided to the vent  131   a  or the integrated controller  300  through the evaporator/heater  138 . The generated wind may pass through the vent  131   a  to be supplied to the inside of the vehicle  100 . 
     More specifically, although not illustrated in the drawings, the air conditioner  131  may supply air to the integrated controller  300  because a part of the air conditioning duct connected to the center console of the vehicle  100  branches to the integrated controller  300 . 
     At this time, the supplied air may be dehumidified air when the evaporator/heater  138  operates as an evaporator, and may be hot air when the evaporator/heater  138  operates as a heater. 
     More specifically, as illustrated in  FIG.  3   , the air conditioner  131  may include the air conditioning switch  131   b , the air conditioning control unit  132 , a flow control valve  135 , the evaporator/heater  138 , the driver  139 , and an air conditioner compressor  137 . The driver  139  may include the fan  136  and the motor  136   a.    
     The air conditioning switch  131   b , the air conditioning control unit  132 , and the flow control valve  135  constituting the air conditioner  131  may communicate with each other through a vehicle network NT. 
     The air conditioning control unit  132  may also communicate with the integrated controller  300  through the vehicle network NT. Therefore, the air conditioning control unit  132  included in the air conditioner  131  may generate a control signal according to a signal received from the integrated controller  300 . 
     The vehicle network NT may adopt a communication standard, such as Media Oriented Systems Transport (MOST) having communication speed of a maximum of 24.5 Mbps (Mega-bits per second), FlexRay having communication speed of a maximum of 10 Mbps, Controller Area Network (CAN) having communication speed from 125 kbps (kilo-bits per second) to 1 Mbps, and Local Interconnect Network (LIN) having communication speed of 20 kbps. The vehicle network NT may adopt one or more communication standards of MOST, FlexRay, CAN, and LIN. 
     In the air conditioner  131 , the air conditioning switch  131   b  may enable a driver to adjust an amount of airflow, humidity, and a temperature to a desired level, as described above. 
     Therefore, the air conditioner  131  may include the air conditioning control unit  132  for operating the components of the air conditioner  131  based on information input by the driver through the air conditioning switch  131   b . More specifically, the air conditioning control unit  132  may include a flow valve controller  133  for controlling the flow control valve  135  to adjust a flow rate according to a control signal, and an air conditioning controller  134  for adjusting an amount of air conditioning according to a control signal. The air conditioning control unit  132  may generate control signals for the flow valve controller  133  and the air conditioning controller  134  based on an input signal received from the integrated controller  300 , in addition to information received from the driver through the air conditioning switch  131   b.    
     The flow valve controller  133  may drive the flow control valve  135  through the vehicle network NT, and the air conditioning controller  134  may itself operate the driver  139  including the fan  136  and the motor  136   a , the air conditioner compressor  137 , and the evaporator/heater  138 . 
     More specifically, the flow valve controller  133  may generate a control signal for driving the flow control valve  135 , which is a valve for controlling a flow rate passing through the branched air duct to the integrated controller  300 . The flow valve controller  133  may control an opening rate of the flow control valve  135  according to an amount of heat generated by the integrated controller  300 . 
     For example, the integrated controller  300  may transfer a measured inside temperature to the air conditioner  131  through the vehicle network NT. At this time, the integrated controller  300  may transmit information about a heat capacity that needs to be dissipated in consideration of a reference temperature required for the integrated controller  300  to operate normally, to the air conditioner  131  through the vehicle network NT. 
     The air conditioning controller  134  of the air conditioner  131  may calculate a total heat capacity based on the information about the heat capacity received from the integrated controller  300  and an air conditioning setting value set by the driver through the air conditioning switch  131   b.    
     Also, the air conditioning controller  134  may generate a signal for an opening rate required by the flow valve controller  133  based on the calculated total heat capacity, and transmit the generated signal for the opening rate to the flow control valve  135  through the vehicle network NT. The air conditioning controller  134  may transmit a vehicle air conditioning control signal to at least one of the driver  139 , the air conditioner compressor  137 , and the evaporator/heater  138 . 
     For example, the air conditioning controller  134  may increase an opening rate of the flow control valve  135 , when an amount of heat generation increases due to continuous operations of the integrated controller  300 , and when additional heat dissipation is required, the air conditioning controller  134  may increase an operation amount of the air conditioner compressor  137 . 
     Also, as an example, when a heat capacity that needs to be dissipated, received from the integrated controller  300 , is small, the air conditioning controller  134  may reduce an opening rate of the flow control valve  135 , thereby reducing cool air that is transmitted to the integrated controller  300 . 
     As described above with reference to  FIG.  2   , the driver  139  may include the fan  136  rotating by the motor  136   a , and when the fan  136  is driven, the air conditioner  131  may generate wind. 
     The generated wind may be provided to the vent  131   a  or the integrated controller  300  through the evaporator/heater  138 , and pass through the vent  131   a  to be supplied to the inside of the vehicle  100 . 
     The air conditioner compressor  137  may be a refrigerant compressor, and when the air conditioner compressor  137  is applied to the vehicle  100 , the air conditioner compressor  137  may generally operate in the state in which a refrigerant and oil are mixed. That is, the air conditioner compressor  137  may convert rotation energy into reciprocating energy through a cylinder to compress a refrigerant, to decrease a temperature, and to generate cold wind through a heat exchanger. 
     Therefore, for example, when wind generated through the driver  139  is generated as cold wind through the air conditioner compressor  137  and then passes through the evaporator  138 , the air conditioner  131  may provide air of low temperature and low humidity to a vehicle indoor environment of high temperature and high humidity in hot weather such as a summer. 
     The integrated controller  300 , which receives air from the air conditioner  131 , may have a structure as illustrated in  FIG.  4   . 
       FIG.  4    is a side view of the integrated controller  300  according to an embodiment of the disclosure.  FIG.  4    illustrates the integrated controller  300  as a structure for covering a plurality of printed circuit boards (PCBs)  411   a ,  411   b , and  411   c  with aluminum housings  410  and  414  configured with a plurality of heat dissipation fins. 
     The plurality of printed circuit boards  411   a ,  411   b , and  411   c  may be configured by mounting a high-performance application processor (AP) or a field-programmable gate array (FPGA) on a conventional micro controller unit (MCU). This is because high-performance and high-speed operations are required when sensor fusion and deep-running image recognition technology are applied by mounting various sensors to operate the ADAS. 
     Therefore, in  FIG.  4   , the first printed circuit board  411   a , the second printed circuit board  411   b , and the third printed circuit board  411   c  may correspond to the MCU, the AP, and the FPGA chip, respectively. The printed circuit boards  411  ( 411   a  to  411   c ) may be high-heating elements, and generally designed to be in direct contact with the housings  410  and  414 . At the upper end of each printed circuit board  411 , a thermal grease  412  ( 412   a  to  412   d ) may be applied on bolt fastening portions  415  ( 415   a  to  415   c ) connecting the housings  410  and  414  to the printed circuit board  411  to improve heat transfer efficiency. 
     That is, the thermal grease  412  ( 412   a  to  412   d ) may be provided on at least a part of one surface of the at least one printed circuit board  411  and at least a part of the surfaces of the housings  410  and  414  to be positioned between the printed circuit board  411  and the housings  410  and  414 . 
     The housings  410  and  414  may also include a cover housing  410  and a base housing  414 . 
     The printed circuit board  411  may be disposed in the inside of at least one of the cover housing  410  and the base housing  414 , and the thermal grease  412  may be provided between the printed circuit board  411  and the housings  410  and  414 . 
     Heat dissipation fins P 41  and P 42  provided on the housings  410  and  414  may protrude from at least one upper surface of the cover housing  410  and from at least one lower surface of the base housing  414 . 
     The integrated controller  300  of  FIG.  4    may branch the air conditioning duct connected to the center console from the air conditioner  131  and fasten the air conditioning duct to the upper end of the integrated controller  300  in order to increase an heat dissipation effect by applying the heat dissipation fins P 41  and P 42  to the upper and lower housings  410  and  414 . More specifically, at the upper end of the integrated controller  300 , the flow control valve  135  of the air conditioner  131  may be positioned to control an amount of air that is transmitted to the integrated controller  300 . This configuration will be described in detail in the following embodiment referring to  FIGS.  5  and  7   . 
     In addition, as will be described later with reference to  FIG.  5   , the integrated controller  300  may be positioned at the top of a chassis frame  310  of the vehicle  100  so that inside heat of the lower housing  414  of the integrated controller  300  is transferred to the chassis frame  310 , and the chassis frame  310  and the integrated controller  300  may be cooled by convection caused by airflow in the lower portion of the vehicle  100  when the vehicle  100  is driven. 
     More specifically,  FIG.  5    is a schematic view for describing interactions between an air conditioner and an integrated controller according to an embodiment of the disclosure, and  FIG.  6    is a flowchart illustrating a method for controlling a vehicle according to an embodiment of the disclosure.  FIGS.  5  and  6    relate to an embodiment for optimizing the heat dissipation performance of the integrated controller  300  when the air conditioner  131  operates in summer. 
     For example, as illustrated in  FIG.  5   , the integrated controller  300  may be provided as a structure capable of receiving air from an air conditioning duct branched upward from the upper housing  410 , and the flow control valve  135  for controlling an amount of air transmitted from the air conditioning duct may be located between the air conditioning duct and the integrated controller  300 . 
     Accordingly, the flow control valve  135  may control an amount of air that is transmitted to the integrated controller  300  according to a control signal from the flow valve controller  133  of the air conditioning control unit  132 . 
     In addition, the chassis frame  310  may be positioned at the lower end of the integrated controller  300 , and the chassis frame  310  and the integrated controller  300  may be cooled by convection caused by airflow in the lower portion of the vehicle  100  when the vehicle  100  is driven. 
     At this time, the flow valve controller  133  for controlling the flow control valve  135  may control an opening rate of the flow control valve  135  based on an input signal input through the air conditioning switch  131   b  and temperature information of the integrated controller  300 . 
     That is,  FIG.  6    is a flowchart illustrating a vehicle control method for dissipating the heat of the integrated controller  300  by using the air conditioner  131  in summer. 
     First, the integrated controller  300  and the air conditioner  131  mounted on the vehicle  100  may start controlling the vehicle  100  according to the embodiment of the disclosure when the vehicle  100  starts, in operations  601  and  610 . 
     The integrated controller  300  and the air conditioner  131  may be included in a separate vehicle and operate through the vehicle network NT. As illustrated in  FIG.  6   , the air conditioner  131  may receive information about a heat capacity that needs to be dissipated, calculated by the integrated controller  300 , from the integrated controller  300 . 
     The integrated controller  300  and the air conditioner  131  may operate independently in parallel. For convenience of description, an operation method of the integrated controller  300  will be first described as follows. 
     When the vehicle  100  starts in operation  601 , the integrated controller  300  may measure an inside temperature of the integrated controller  300  configured with at least one chip, in operation  602 . The first printed circuit board  411   a , the second printed circuit board  411   b , and the third printed circuit board  411   c  of the integrated controller  300  configured with at least one chip may be the MCU, the AP, and the FPGA chip, respectively. When the first printed circuit board  411   a  is a main printed circuit board, the first printed circuit board  411   a  may diagnose a chip temperature of the first printed circuit board  411   a , a chip temperature of the second printed circuit board  411   b  received from the second printed circuit board  411   b , and a chip temperature of the third printed circuit board  411   c  received from the third printed circuit board  411   c  to calculate a heat capacity A that needs to be dissipated, in consideration of a reference temperature at which the integrated controller  300  operates normally, in operation  604 . At this time, the integrated controller  300  may determine whether heat dissipation is needed in consideration of the reference temperature at which the integrated controller  300  operates normally, in operation  603 . Accordingly, when the integrated controller  300  determines that heat dissipation is needed (YES in operation  603 ), the integrated controller  300  may calculate a heat capacity A that needs to be dissipated, and transmit the calculated heat capacity A to the air conditioner  131 . 
     Then, the air conditioner  131  may obtain an air conditioning setting value input by the driver through the air conditioning switch  131   b  when the vehicle  100  starts, in operation  611 . At this time, the air conditioning setting value input by the driver may include an air volume and temperature information. In addition, the air conditioner  131  may obtain a vehicle indoor temperature to set an air conditioning value according to the air conditioning setting value, in operation  612 . 
     The air conditioner  131 , which has received the heat capacity A required for heat dissipation of the integrated controller  300  from the integrated controller  300 , may calculate a total heat capacity B required for heat dissipation in consideration of both the air conditioning setting value and the heat capacity A, in operation  613 . When the total heat capacity B is larger than a reference value which is a reference level allowing air-conditioning control with the air conditioning setting value set by the driver (YES in operation  614 ), the air conditioner  131  may compensate for the air conditioning setting value, in operation  615 . For example, the air conditioner  131  may decrease the setting temperature, and increase the air volume. 
     In contrast, when the total heat capacity B is smaller than the reference value which is the reference level allowing vehicle air conditioning control with the air conditioning setting value set by the driver (NO in operation  614 ), the air conditioner  131  may control the flow control valve  135  to dissipate heat of the integrated controller  300 . That is, the integrated controller  300  may open the flow control valve  135 . 
       FIGS.  5  and  6    described above correspond to an embodiment for optimizing the heat dissipation performance of the integrated controller  300  in summer. 
       FIGS.  7  and  8    illustrate a method of supplying heated air to prevent the temperature of the integrated controller  300  from falling excessively in winter. 
     For example, as illustrated in  FIG.  7   , which is the same as  FIG.  5   , the integrated controller  300  may be provided as a structure capable of receiving air from the air conditioning duct branched upward from the upper housing  410 , and the flow control valve  135  for controlling an amount of air transmitted from the air conditioning duct may be positioned between the air conditioning duct and the integrated controller  300 . 
     Thus, when air transmitted from the air conditioning duct is hot wind, the integrated controller  300  may absorb heat from the hot wind passing through the flow control valve  135 . 
     Accordingly, the flow control valve  135  may control an amount of air that is transmitted to the integrated controller  300  according to a control signal from the flow valve controller  133  of the air conditioning control unit  132 . 
     In addition, the chassis frame  310  may be positioned below the integrated controller  300 , and accordingly, when the vehicle  100  is driven, heat of the chassis frame  310  and the integrated controller  300  may be dissipated by convection caused by airflow in the lower portion of the vehicle  100 . 
     At this time, the flow valve controller  133  for controlling the flow control valve  135  may control an opening rate of the flow control valve  135  based on an input signal input through the air conditioning switch  131   b  and temperature information of the integrated controller  300 . 
     That is,  FIG.  8    is a flowchart illustrating a vehicle control method for preventing the temperature of the integrated controller  300  from falling excessively by using the air conditioner  131  in winter. 
     First, the integrated controller  300  and the air conditioner  131  mounted on the vehicle  100  may start controlling the vehicle  100  according to an embodiment of the disclosure when the vehicle  100  starts, in operations  801  and  810 . 
     The integrated controller  300  and the air conditioner  131  may be included in a separate vehicle and operate through the vehicle network NT. As illustrated in  FIG.  6   , the air conditioner  131  may receive a value of a heat capacity that needs to be dissipated, calculated by the integrated controller  300 , from the integrated controller  300 . 
     The integrated controller  300  and the air conditioner  131  may operate independently in parallel. For convenience of description, an operation method of the integrated controller  300  will be first described as follows. 
     When the vehicle  100  starts in operation  801 , the integrated controller  300  may measure an inside temperature of the integrated controller  300  configured with at least one chip, in operation  802 . Herein, the first printed circuit board  411   a , the second printed circuit board  411   b , and the third printed circuit board  411   c  of the integrated controller  300  configured with at least one chip may correspond to the MCU, the AP, and the FPGA chip, respectively. When the first printed circuit board  411   a  is a main printed circuit board, the first printed circuit board  411   a  may diagnose a chip temperature of the first printed circuit board  411   a , a chip temperature of the second printed circuit board  411   b  received from the second printed circuit board  411   b , and a chip temperature of the third printed circuit board  411   c  received from the third printed circuit board  411   c  to calculate a heat capacity value C for heat absorption in consideration of a reference temperature at which the integrated controller  300  operates normally, in operation  804 . At this time, the integrated controller  300  may determine whether heat absorption is needed, in consideration of a predetermined normal operation temperature of the integrated controller  300  as a reference value, in operation  803 . Accordingly, when the integrated controller  300  determines that the heat absorption is needed (YES in operation  803 ), the integrated controller  300  may calculate the heat capacity value C for the heat absorption and transmit the calculated heat capacity value C to the air conditioner  131 . 
     Then, when the vehicle  100  starts, the air conditioner  131  may obtain an air conditioning setting value input by the driver through the air conditioning switch  131   b , in operation  811 . The air conditioning setting value input by the driver may include an air volume and temperature information. In addition, the air conditioner  131  may obtain a vehicle indoor temperature to set an air conditioning value according to the air conditioning setting value, in operation  812 . 
     The air conditioner  131  that has receives the required heat capacity value C of the integrated controller  300  from the integrated controller  300  may calculate a total heat capacity B that needs to be dissipated, in consideration of both the air conditioning setting value and the heat capacity value C, in operation  813 . When the total heat capacity B is larger than a reference value which is a reference level allowing air-conditioning control with the air conditioning setting value set by the driver (YES in operation  814 ), the air conditioner  131  may compensate for the air conditioning setting value, in operation  815 . For example, the air conditioner  131  may decrease the setting temperature, and increase the air volume, thereby discharging hot wind. 
     In contrast, when the total heat capacity B is smaller than the reference value which is the reference level allowing air conditioning control with the air conditioning setting value set by the driver (NO in operation  814 ), the air conditioner  131  may control the flow control valve  135  to dissipate heat of the integrated controller  300 . That is, the integrated controller  300  may open the flow control valve  135 . 
     That is, a case in which the integrated controller  300  is frozen in winter so as not to operate properly may be prevented in advance, as seen from  FIG.  8   . 
       FIG.  9    is a side view of an integrated controller according to another embodiment of the disclosure. In the case of an integrated controller  300  illustrated in  FIG.  9   , the integrated controller  300  may have a structure of covering a plurality of printed circuit boards (PCBs)  911   a ,  911   b  and  911   c  with aluminum housings  910  and  914  configured with a plurality of heat dissipation fins, like the integrated controller  300  shown in  FIG.  4   . 
     The plurality of printed circuit boards  911   a ,  911   b , and  911   c  may be configured by mounting a high performance AP or a high performance FPGA on a MCU. This is because high-performance and high-speed operations are required when sensor fusion and deep-running image recognition technology are applied by mounting various sensors to operate the ADAS. 
     However, as shown in  FIG.  9   , in the lower housing  914 , lower ends of the heat dissipation fins may be flat to maximize thermal conduction with the chassis frame  310 . 
     As is apparent from the above description, the vehicle for reducing the heat generation of the integrated controller equipped with the ADAS, and the method of controlling the vehicle may be provided. 
     Further, the vehicle for preventing the temperature of the integrated controller equipped with the ADAS from falling excessively, and the method of controlling the vehicle may be provided. 
     Further, the integrated controller equipped with the ADAS, the ADAS mounted on the vehicle, may be provided as a structure that is operable in such a way not to be sensitive to an external temperature.

It will be obvious to people of ordinary skill in the art that the present disclosure may be practiced in other forms than the exemplary embodiments as described above without changing the technical idea or essential features of the present disclosure.
