However, the ship display device disclosed in Patent Document 1 is not configured to recognize the cooling failure of each of the two cooling water passages, so that the operator cannot recognize the abnormality at an early stage. There's a problem. On the other hand, it is conceivable to install temperature sensors in each of the two cooling water passages to display all the measured values detected by each temperature sensor, but in order to improve visibility, the display area must be enlarged. However, there is a problem that the size of the display device becomes large.

A mixture of intake air and fuel is supplied to each combustion chamber. At the rear of the engine 12, an electronically controlled throttle 29 that controls the flow rate when supplying intake air to each combustion chamber is arranged.

An ECU (engine control unit) 50 is attached to the front surface of the crankcase 24. The ECU 50 functions as a display control device that controls the display of the display device 60.

Further, the outboard motor 10 has a cooling water passage structure for cooling the engine 12 by using seawater in the sea or freshwater in a lake where the ship 100 navigates as cooling water.
FIG. 4 is a schematic view showing an example of the cooling water passage structure of the outboard motor 10.
The cooling water passage structure 40 includes a water intake 41, a water pump 42, a water supply passage 43, a combustion chamber peripheral water jacket 44R, 44L, an exhaust port peripheral water jacket 45R, 45L, a cylinder peripheral water jacket 46R, 46L, a thermostat 47R, 47L, etc. Has.
The cooling water passage structure 40 of this embodiment has two cooling water passages 40R and 40L in order to cool the right bank portion 25R and the left bank portion 25L, respectively. The cooling water passage 40R is a passage that passes through the water supply passage 43, the water jacket around the combustion chamber 44R, the water jacket around the exhaust port 45R, the water jacket around the cylinder 46R, and the thermostat 47R. The cooling water passage 40L is a passage that passes through the water supply passage 43, the water jacket around the combustion chamber 44L, the water jacket around the exhaust port 45L, the water jacket around the cylinder 46L, and the thermostat 47L.

The cooling water passage structure 40 functions by driving the water pump 42 provided in the drive shaft housing 18 by the drive shaft 19. By driving the water pump 42, cooling water is taken in from the water intake port 41 formed on the side surface of the gear case 20. The taken-in cooling water is branched into the right bank portion 25R side and the left bank portion 25L side by the water supply passage 43. The branched cooling water first flows to the combustion chamber surrounding water jackets 44R and 44L of the cylinder heads 26 of the right bank portion 25R and the left bank portion 25L, respectively, and cools the combustion chamber surroundings of each cylinder. Next, the cooling water flows to the exhaust port peripheral water jackets 45R and 45L of the right bank portion 25R and the left bank portion 25L, respectively, and cools the exhaust port surroundings of each cylinder. Next, the cooling water flows to the cylinder block water jackets 46R and 46L of the cylinder block 25 of the right bank portion 25R and the left bank portion 25L, respectively, and cools the cylinder block of each cylinder. After that, the cooling water is drained to the outside of the engine 12 via the thermostats 47R and 47L, respectively.

In the outboard motor 10, in order to take in outside water such as seawater and fresh water as cooling water, foreign matter such as mud and sand may be taken in together with the cooling water. When foreign matter is taken in, it accumulates in the cooling water passages 40R and 40L and is blocked, causing cooling failure. When two cooling water passages 40R and 40L are provided so that the right bank portion 25R and the left bank portion 25L can be cooled as in the engine 12 of this embodiment, even if one of the cooling water passages is poorly cooled. It is necessary to make the operator aware. Therefore, in the outboard motor 10, the right bank temperature sensor 31R and the left bank temperature sensor 31L are arranged in the right bank portion 25R and the left bank portion 25L, respectively. The right bank temperature sensor 31R detects the temperature of the side wall of the cylinder head 26 of the right bank portion 25R on the exhaust port side. The left bank temperature sensor 31L detects the temperature of the side wall of the cylinder head 26 of the left bank portion 25L on the exhaust port side. However, the right bank temperature sensor 31R and the left bank temperature sensor 31L may detect the temperature at which cooling is poor, for example, the temperature of the cooling water.
Further, in the outboard motor 10 of the present embodiment, in order to improve the controllability of the engine 12, the temperature of other parts is also detected. Specifically, as shown in FIG. 3, the outboard motor 10 has a cylinder block wall temperature sensor 32, an intake air temperature sensor 33, and the like. The cylinder block wall temperature sensor 32 detects the wall temperature around the thermostats 47R and 47L in the cylinder block 25. Further, the intake air temperature sensor 33 detects the temperature of the intake air.

Next, as an example of displaying the operating state of the outboard motor 10 on the display device 60, the temperature detected by the right bank temperature sensor 31R, the left bank temperature sensor 31L, the cylinder block wall temperature sensor 32, and the intake air temperature sensor 33. Will be described.
Among the temperature sensors described above, the right bank temperature sensor 31R and the left bank temperature sensor 31L are sensors that detect common items. When only the temperature detected by one of the right bank temperature sensor 31R and the left bank temperature sensor 31L is displayed and the temperature detected by the other temperature sensor is not displayed, the operator operates the other temperature sensor. Even if the detected temperature is abnormal, it cannot be recognized.
On the other hand, if all the temperatures detected by the right bank temperature sensor 31R and the left bank temperature sensor 31L are displayed, the size of the display device 60 becomes large. Further, the display device 60 for the outboard motor 10 equipped with the right bank temperature sensor 31R and the left bank temperature sensor 31L and the display device for the outboard motor equipped with only one temperature sensor have a common display device. It cannot be transformed.

Therefore, in the outboard motor 10 of the present embodiment, when the ECU 50 displays the temperature detected by the plurality of temperature sensors that detect common items on the display device 60, the temperature detected by the plurality of temperature sensors is normal. If it is within the range of, the average value is displayed on the display device 60. On the other hand, when any of the measured values detected by the plurality of temperature sensors is an abnormal temperature exceeding the normal range, the ECU 50 gives priority to the abnormal temperature and displays it on the display device 60.

Next, the display control process when the ECU 50 displays the temperature detected by the temperature sensor will be described.
First, the configuration of the ECU 50 will be described with reference to FIG.
As shown in FIG. 5, the ECU 50 includes a CPU 51, a memory 52, an input circuit 53, an output circuit 54, and the like.
The CPU 51 is a so-called computer, and controls the engine 12 and the display of the display device 60 by executing a program stored in the memory 52. The CPU 51 corresponds to an example of display control means.

The memory 52 includes a ROM, a RAM, an EEPROM, and the like.
The memory 52 stores a program executed by the CPU 51 to control the engine 12 and the display of the display device 60. Further, in the memory 52 of this embodiment, a threshold value for determining whether the temperature detected by each temperature sensor is a normal temperature or an abnormal temperature is stored.

Signals are input to the input circuit 53 from various sensors inside and outside the outboard motor 10. Here, each signal when the right bank temperature sensor 31R, the left bank temperature sensor 31L, the cylinder block wall temperature sensor 32, and the intake air temperature sensor 33 detect the temperature is input to the input circuit 53.
The output circuit 54 transmits a signal for controlling the display to the display device 60. The CPU 51 performs a process described later based on the signal from each sensor input via the input circuit 53, and outputs the signal based on the process to the display device 60 via the output circuit 54. The output circuit 54 and the display device 60 are connected wirelessly or by wire.

Next, the display control process by the ECU 50 will be described with reference to the flowchart of FIG. The flowchart of FIG. 6 is realized by the CPU 51 executing the program stored in the memory 52. The flowchart of FIG. 6 is started by starting the outboard motor 10. Here, a case where the right bank temperature sensor 31R and the left bank temperature sensor 31L, which are temperature sensors for detecting common items, display the detected temperature will be described.

In S10, the CPU 51 acquires the temperature signal detected by the right bank temperature sensor 31R and the left bank temperature sensor 31L.
In S11, the CPU 51 determines whether or not the temperature acquired from the right bank temperature sensor 31R (hereinafter referred to as the right bank temperature) is lower than the superheat side threshold value. The superheat side threshold value is temperature information for determining cooling failure. Here, the temperature lower than the overheating side threshold value is in the normal range. On the other hand, the temperature above the superheat side threshold value is an abnormal temperature, and there is a possibility of cooling failure. This superheat side threshold value is stored in the memory 52 in advance.

In S11, if the right bank temperature is equal to or higher than the superheat side threshold value, the process proceeds to S12.
In S12, the CPU 51 determines whether or not the temperature acquired from the left bank temperature sensor 31L (hereinafter referred to as the left bank temperature) is lower than the superheat side threshold value. This superheat side threshold value is the same as the superheat side threshold value as determined in S11, and the same applies thereafter.
In S12, if the left bank temperature is equal to or higher than the superheat side threshold value, the process proceeds to S13. Here, when proceeding to S13, it is a case where both the right bank temperature and the left bank temperature are overheated.
In S13, the CPU 51 compares the right bank temperature and the left bank temperature, and displays the higher temperature on the display device 60. That is, when any of the temperatures is abnormal, the CPU 51 displays a more abnormal temperature. At this time, the CPU 51 gives a warning to the operator to recognize that the temperature is abnormal. The warning includes a process of blinking the displayed temperature, displaying a warning light, and emitting a sound or a voice via the notification device 107 or the like to recognize that the temperature is abnormal. In this way, when all of them have abnormal temperatures, the operator can accurately recognize the degree of abnormality by displaying the abnormal temperature.

FIG. 7 is a diagram showing a display example when the temperature is displayed on the display device 60.
The display device 60 has a display unit 61 and an operation unit 65. The display unit 61 is divided into three display areas 62 to 64.
In the display area 62, an average value of measured values detected by a plurality of sensors that detect common items and an abnormal measured value are displayed. By displaying only one value in the display area 62 without displaying a plurality of values, the visibility of the display unit 61 can be improved. In this embodiment, the temperature detected by the right bank temperature sensor 31R or the left bank temperature sensor 31L, the average temperature, and the like are displayed in the display area 62. The temperature displayed in the display area 62 of FIG. 7 is displayed in blinking so that it can be recognized that the temperature is an abnormal temperature.
The measured values detected by other sensors are displayed in the display areas 63 and 64. In this embodiment, the temperature detected by the cylinder block wall temperature sensor 32 is displayed in the display area 63, and the temperature detected by the intake air temperature sensor 33 is displayed in the display area 64.
The operation unit 65 is a menu button, a selection button, a setting button, and the like. The operator can switch the display mode by operating the operation unit 65.

Returning to FIG. 6, in S12, if the left bank temperature is lower than the superheat side threshold value, the process proceeds to S14.
In S14, the CPU 51 determines whether the left bank temperature is higher than the supercooling side threshold. The supercooling side threshold value is temperature information for determining supercooling. Here, a temperature higher than the supercooling side threshold is in the normal range. On the other hand, the temperature below the supercooling side threshold is abnormal. The supercooling side threshold value is stored in the memory 52 in advance.
In S14, if the left bank temperature is equal to or lower than the supercooling side threshold value, the process proceeds to S15. Here, the case of proceeding to S15 is a case where the right bank temperature is overheated and the left bank temperature is supercooled.
In S15, the CPU 51 displays the right bank temperature on the display device 60. That is, when the CPU 51 has an abnormal temperature on the superheated side and an abnormal temperature on the supercooled side, the CPU 51 preferentially displays the abnormal temperature on the superheated side. At this time, the CPU 51 gives the same warning as described above in order to make the operator recognize that the temperature is abnormal. Here, in the case of an abnormal temperature on the overheated side, if the abnormality progresses, a serious trouble occurs in which the engine 12 is stopped due to seizure or the like. Therefore, by giving priority to displaying the abnormal temperature on the overheated side, the operator can accurately recognize the degree of abnormality.

In S14, if the left bank temperature is higher than the supercooling side threshold value, the process proceeds to S16. Here, the case of proceeding to S16 is a case where the right bank temperature is overheated and the left bank temperature is in the normal range.
In S16, the CPU 51 displays the right bank temperature on the display device 60. That is, when there is an abnormal temperature and a normal temperature, the CPU 51 preferentially displays the abnormal temperature. At this time, the CPU 51 gives the same warning as described above in order to make the operator recognize that the measured value is abnormal. In this way, when there is an abnormal temperature and a normal temperature, the operator can recognize the abnormality at an early stage by displaying the abnormal temperature.

In S11, if the right bank temperature is lower than the superheat side threshold value, the process proceeds to S17.
In S17, the CPU 51 determines whether or not the right bank temperature is higher than the supercooling side threshold value. This supercooling side threshold value is the same as the supercooling side threshold value as determined in S14, and the same applies thereafter.
In S17, if the right bank temperature is equal to or lower than the supercooling side threshold value, the process proceeds to S18.
In S18, the CPU 51 determines whether the left bank temperature is lower than the superheated threshold. This process is the same as in S12.

In S18, if the left bank temperature is equal to or higher than the superheat side threshold value, the process proceeds to S19. Here, the case of proceeding to S19 is a case where the right bank temperature is supercooled and the left bank temperature is overheated.
In S19, the CPU 51 displays the left bank temperature on the display device 60. That is, when the CPU 51 has an abnormal temperature on the supercooled side and an abnormal temperature on the superheated side, the CPU 51 preferentially displays the abnormal temperature on the superheated side. At this time, the ECU 50 gives the operator the same warning as described above.

In S18, if the left bank temperature is lower than the superheat side threshold value, the process proceeds to S20.
In S20, the CPU 51 determines whether the left bank temperature is higher than the supercooling side threshold.
In S20, when the left bank temperature is equal to or lower than the supercooling side threshold value, the process proceeds to S21. Here, the case of proceeding to S21 is a case where both the right bank temperature and the left bank temperature are supercooled.
In S21, the CPU 51 compares the right bank temperature and the left bank temperature, and displays the lower temperature on the display device 60. That is, when any of the temperatures is abnormal, the CPU 51 preferentially displays the abnormal temperature. At this time, the CPU 51 warns the operator in the same manner as described above.

On the other hand, in S20, when the left bank temperature is higher than the supercooling side threshold value, the process proceeds to S22. Here, the case of proceeding to S22 is a case where the right bank temperature is supercooled and the left bank temperature is normal.
In S22, the CPU 51 displays the right bank temperature on the display device 60. That is, when there is an abnormal temperature and a normal temperature, the CPU 51 preferentially displays the abnormal temperature. At this time, the CPU 51 warns the operator in the same manner as described above.

In S17, if the right bank temperature is higher than the supercooling side threshold value, the process proceeds to S23. The case of proceeding to S23 is the case where the right bank temperature is normal.
In S23, the CPU 51 determines whether or not the left bank temperature is lower than the superheat side threshold. This process is the same as S18.
In S23, when the left bank temperature is equal to or higher than the superheat side threshold value, the process proceeds to S24. The case of proceeding to S24 is a case where the right bank temperature is normal and the left bank temperature is overheated.
In S24, the CPU 51 displays the left bank temperature on the display device 60. That is, when there is a normal temperature and an abnormal temperature, the CPU 51 preferentially displays the abnormal temperature. At this time, the CPU 51 warns the operator in the same manner as described above.

In S23, if the left bank temperature is lower than the superheat side threshold value, the process proceeds to S25.
In S25, the CPU 51 determines whether the left bank temperature is higher than the supercooling side threshold. This process is the same as S14.
In S25, if the left bank temperature is equal to or lower than the supercooling side threshold value, the process proceeds to S26. The case of proceeding to S26 is a case where the right bank temperature is normal and the left bank temperature is supercooled.
In S26, the CPU 51 displays the left bank temperature on the display device 60. That is, when there is a normal temperature and an abnormal temperature, the CPU 51 preferentially displays the abnormal temperature. At this time, the CPU 51 warns the operator in the same manner as described above.

In S25, if the left bank temperature is larger than the supercooling side threshold value, the process proceeds to S27. The case of proceeding to S27 is a case where both the right bank temperature and the left bank temperature are normal.
In S27, the CPU 51 displays the average value calculated from the right bank temperature and the left bank temperature or a preset representative temperature on the display device 60. Here, the representative temperature is a temperature detected by a preset temperature sensor among a plurality of temperature sensors, and a higher temperature (highest temperature) or a lower temperature (lowest temperature) of the plurality of temperature sensors. ). Therefore, when both the right bank temperature and the left bank temperature are normal, by displaying only one value, the visibility of the display unit 61 is improved without increasing the size of the display device 60. Can be made to.

As described above, in the present embodiment, the CPU 51 displays the average value or the representative measured value on the display device 60 when the measured value detected by the plurality of sensors that detect the common item is within the normal range. To control. On the other hand, when any of the measured values detected by the plurality of sensors is an abnormal measured value exceeding the normal range, the CPU 51 controls so that the abnormal measured value is preferentially displayed on the display device 60. By displaying the abnormal measured value on the display device 60 with priority in this way, the operator can recognize the abnormality of the operating state of the outboard motor 10 at an early stage. Further, by displaying any one of the average value, the representative measured value, and the abnormal measured value, the visibility of the measured value detected by a plurality of sensors is improved without increasing the size of the display device 60. Can be made to. In this case, the display device 60 can be shared with the display device of the outboard motor, which does not need to detect common items.

In this embodiment, the case where the sensor that detects a common item is a temperature sensor and the measured value is temperature has been described, but the present invention is not limited to this case, and a sensor that detects other measured values may be used. .. Further, in this embodiment, the case of displaying the numerical value as the case of displaying the measured value has been described, but the case is not limited to this case. When displaying the measured value, for example, a case where a stepwise indicator or the like is displayed instead of the numerical value is included. Further, in this embodiment, the case where the plurality of sensors for detecting a common item is two has been described, but the case is not limited to this case, and the number may be three or more.

Further, in this embodiment, the engine 12 of the outboard motor 10 is a V-type engine, and the right bank temperature sensor 31R and the left bank temperature sensor in which a plurality of sensors are arranged in the right bank portion 25R and the left bank portion 25L, respectively. It is 31L. The V-type engine of the outboard motor 10 has cooling water passages 40R and 40L for taking in outside water in the right bank portion 25R and the left bank portion 25L, and cooling failure occurs in only one of the cooling water passages 40R and 40L.
