As shown in FIG. 5, the PTT switches 46 and 4 provided on the remote control box 13 and the outboard motor 3 are provided.
The UP side and the DN (DOWN) side of 7 are connected to PTT relays 53 (UP and DN), respectively, and serve as a power source of a hydraulic device that is a power means (not shown) for tilting the outboard motor 3 up and down. To drive.

Specifically, for example, a signal (cam angle signal) of a cam shaft (not shown) of the engine 15 is input from the cam shaft signal detector 58 to the input circuit 5.
9 through the arithmetic unit 60 (CPU, R
AM / ROM). Hereinafter, the rotation speed signal of the engine 15 is the crank angle signal detector 61 (revolution speed detector).

Then, signals from a stop (emergency stop) switch 69 and a setting switch 70, which will be described later, are also input to the calculation unit 60.

The information input from the respective devices to the control device 52 is appropriately arithmetically processed in the arithmetic unit 60, and is output to the respective devices inside and outside the outboard motor 3 via the output circuit 71. Specifically, for example, the control relay 57 of the PTT device 41 is operated to drive the PTT motor 54. In addition, for example, the fuel injection amount information is monitored by the injector 72, the intake air amount adjustment signal is monitored by an unillustrated step motor, solenoid valve, or the like of the actuator 73, and the engine speed signal or a signal for transmitting abnormality of each device is monitored. 44 warning lights 42 (LE

Further, the arithmetic unit 60 outputs an ignition signal from the output circuit 71 to the ignition coil 77 via the ignition device 75 (the power supply circuit 76 is connected).

By the way, the ship 1 is, for example, while the ship is stopped or the hull 2
At the time of landing, the outboard motor 3 may be raised above the water surface by the tilt operation. In the invention of the present application, when the operator performs the tilt operation of the outboard motor 3, the maximum tilt-up position of the outboard motor 3 is described below so that a part of the outboard motor 3 does not interfere with the hull 2. It can be easily set by the stop position setting method.

The first tilt-up stop position setting method is as follows:
The operator operates the PTT switches 46 and 47 to tilt up the outboard motor 3 to a desired tilt-up position where the outboard motor 3 does not interfere with the hull 2, and then operates the setting switch 70 dedicated to the setting operation to control the controller. Operation unit 60 of 52
Let the outboard motor 3 know that it is at the desired tilt angle,
The tilt angle signal of the outboard motor 3 from the engine tilt angle detector 48 obtained at the same time is stored. When the desired tilt-up position is set normally, the warning light 42 (LED or the like) of the instrument provided on the instrument panel 7 or the buzzer 9 for warning is operated (flashing or the like) to set the operator. Signal completion.

Further, in order to prevent erroneous recognition of the engine inclination angle detector 48 signal due to noise or the like, the inclination angle signal at the time of the setting operation is detected a plurality of times, and the setting is performed only when these signals match under a predetermined condition. You may make it memorize | store as a value.

Then, the stored set value is the control device 52.
The stored value is stored in a memory device 78 (see FIG. 6) such as an EEPROM that can retain the stored value even when the power is turned off.

The second tilt-up stop position setting method is as follows:
The procedure is the same as the first method up to the point where the operator operates the PTT switches 46 and 47 to tilt up the outboard motor 3 to a desired tilt up position where the outboard motor 3 does not interfere with the hull 2. The setting switch 70 is operated to cause the section 60 to recognize that the outboard motor 3 is at the desired tilt angle and to store the tilt angle signal of the outboard motor 3 from the engine tilt angle detector 48 obtained at the same time. In case of method,
For example, during normal use (operation), the operator may unknowingly touch the setting switch 70 and erroneously set it. Therefore, in this second method, the tilt-up stop position is set without using a dedicated switch or the like. The flowchart is shown in FIG.

As shown in FIG. 7, when the operator arbitrarily sets the tilt-up stop position, first, the controller 52 is set.
Determines in step 1-1 whether the engine 15 is stopped. The reason is that the tilt-up operation of the outboard motor 3 is not normally performed while the engine 15 is operating.

When it is determined that the engine 15 is stopped, the controller 52 determines in step 1-2 whether or not the tilt-up angle is equal to or greater than the set lower limit value to prevent erroneous setting.

When it is determined that the tilt-up angle is equal to or greater than the set lower limit value, the control device 52 detects the state of a predetermined switch and determines in step 1-3 whether or not it is the set condition state. In this second method, the tilt-up stop position is set without using a dedicated switch,
Under the conditions described above, that is, when the engine 15 is stopped and the tilt-up angle is equal to or larger than the set lower limit value, a switch operation that is not normally performed is performed, so that this operation signal is output in step 1-4.
The engine tilt angle detector 4 which makes the calculation unit 60 of No. 2 recognize that the outboard motor 3 is at the desired tilt angle and is obtained at the same time
It functions as a signal for storing the tilt angle signal of the outboard motor 3 from 8.

As a specific example of the switch operation condition which is not normally performed, for example, a shift (neutral) switch 68 is used to perform a shift operation or a throttle operation within a predetermined time more than a set number of times, for example, three times within 5 seconds. In the above case, the calculation unit 60 is made to recognize that the outboard motor 3 is at the desired tilt angle, and the tilt angle signal of the outboard motor 3 from the engine tilt angle detector 48 obtained at the same time is stored.

As another specific example of other conditions, for example, a stop (emergency stop) switch 69 that is used in an emergency to stop the engine 15 in an emergency is used to set ON / OFF operation of this switch within a predetermined time. When it is performed more than once, for example, three times or more in one second, the calculation unit 60 recognizes that the outboard motor 3 has the desired tilt angle, and the outboard from the engine tilt angle detector 48 obtained at the same time. The tilt angle signal of the machine 3 is stored.

Further, the above-mentioned conditions may be combined. For example, it is conceivable that a shift operation or a throttle operation is performed a preset number of times or more within a predetermined time while the stop (emergency stop) switch 69 is turned on. By applying such a switch operation condition that is not normally performed, it is not necessary to newly provide a dedicated switch, and it can be performed only by changing the program of the control device 52, so that there are great advantages in terms of cost and layout.

In any case, when the desired tilt-up position is normally set in step 1-4,
In step 1-5, the controller 52 activates (flashes) the warning lights 42 (LEDs and the like) of the instruments and the warning buzzer 9 provided on the instrument panel 7 to notify the operator of the completion of the setting. .

The third tilt-up stop position setting method is as follows:
Tilt up position, that is, engine tilt angle detector 4
8 is equipped with, for example, a variable resistance device (not shown) for manually instructing a value corresponding to the resistance value output, and the resistance value corresponding to the tilt-up position desired by the user using this variable resistance device. Is directly input to the control device 52 to cause the calculation unit 60 to recognize the desired inclination angle of the outboard motor 3.

The fourth tilt-up stop position setting method is as follows:
As shown in FIG. 6, the communication interface (I / F) 7
The communication device 80 is connected to the arithmetic unit 60 of the control device 52 via 9 and the personal computer (not shown) or the like is used to make the arithmetic unit 60 correspond to the desired tilt-up position of the outboard motor 3. A set value, that is, a tilt angle is input and recognized.

FIG. 8 shows a PTT showing a second embodiment of the present invention.
FIG. 9 is a circuit diagram of the device 41, and FIG. 9 is a system diagram showing a second embodiment of a control device 52 for the entire outboard motor 3 including the PTT device 41. The same components as those in the first embodiment are designated by the same reference numerals. As shown in FIGS. 8 and 9, the UP side of the PTT switches 46 and 47 provided on the remote control box 13 and the outboard motor 3 and the DN (DOW).
N) side is input to the control device 52 respectively, and the calculation unit 6
0 operates the PTT relay 53 according to the input signals from the PTT switches 46 and 47 to drive the PTT motor 54.

Here, the fifth tilt-up stop position setting method utilizes the second embodiment of the present invention described above, and the PTT switches 46 and 47 are set to P in normal times.
It is used for the purpose of driving the TT motor 54 and tilting the outboard motor 3.

Then, as shown in FIG. 3B, for example, by pushing a mode (MODE) switch 81 provided adjacent to the PTT switches 46 and 47 (setting mode state), the arithmetic unit 60 of the control unit 52. Is PTT switch 4
The UP / DN (DOWN) operation signal from 6, 47 is detected as a tilt-up setting signal.

In the setting mode state, the tachometer 8 and the tilt angle display device 43 and the trim meter 45 provided on the multi-function monitor 44 are set to display the current tilt-up set value (stored value). , The operator looks at these display devices and sees the PTT switches 46, 47
UP / DN (DOWN) is operated to set an arbitrary tilt angle. Further, the display value of the display device is changed according to the number of operations and the operation time of the PTT switches 46 and 47.

If the PTT switches 46 and 47 are not operated for a certain period of time after the operator sets a desired tilt angle, the arithmetic unit 60 of the control device 52 recognizes the display value of the display device 43 as a new tilt-up setting value. And remember. When the desired tilt-up position is set normally, the control device 52 activates (blinks, etc.) the warning lights 42 (LEDs, etc.) of the instruments and the buzzer 9 for warning, which are provided on the instrument panel 7. To notify the operator that the setting is complete, and
The mode of the TT switches 46 and 47 is returned to the normal mode.

By the way, in the fifth method described above, the setting completion condition is the case where the PTT switches 46 and 47 are not operated for a certain period of time. However, a dedicated setting completion switch (not shown) is additionally provided, or the above-mentioned first method is used. Completion of the setting is completed by the operation unit 60 of the control device 52 by performing a switch operation which is not normally performed as shown in the second method.
May be made to recognize.

Further, as in the second method described above, for example, during normal use (operation) of the ship operator, the mode (M
ODE) switch 81 may be touched and erroneously set. Therefore, various conditions as shown in the second method (the engine 15 is stopped, the tilt-up angle is equal to or more than the set lower limit, and switch operation is not normally performed). The PTT switches 46 and 47 may shift to the setting mode when the above condition is satisfied.

By the way, regarding the tilt-up stop position set by any one of the above-described tilt-up stop position setting methods, the fact that this stop position is stored in the control device 52 and its set value are displayed. It Specifically, for example, set the normal ignition switch 56 to O
When the N operation is performed, the warning lights 42 perform a lamp check (self-check), and at this time, the set value is displayed on the trim meter 45 for a certain time, for example, by an angle display with a pointer.

As another example, the set value is digitally displayed on the tilt angle display device 43 provided on the instrument panel of the tachometer 8 or the multifunction monitor 44, for example. Further, for the sake of simplicity, the display of whether or not the set value of the tilt-up stop position is stored may be displayed by turning on the warning lights 42 or the like.

Next, a tilt-up stop control method will be described.

The tilt-up stop control is performed according to the flowchart shown in FIG. The calculation unit 60 of the control device 52 stores the tilt-up stop position (stop angle) set by any of the tilt-up stop position setting methods described above, and the engine tilt angle detector 4
The tilt-up operation performed by the operator from the signal output from 8
That is, the tilt angle is constantly detected (step 2-
2). The control condition may be that the engine 15 is in the stopped state before the tilt angle is detected (step 2-1).

The control device 52 stops the tilt-up when the tilt angle reaches the stored stop angle A (°), but the outboard motor 3 does not exceed the stop angle A (°) so that the allowance angle α is set. (°) is preset and the outboard motor 3
Exceeds the stop angle-margin angle (A-α (°)) (tilt angle> A-α, step 2-3), the control relay 57 is operated to stop the PTT motor 54, and the outboard motor is operated. The tilt-up of 3 is stopped (step 2-4).

For example, when the operator is performing the tilt-up operation in the steering seat 6 in front of the outboard motor 3, when the tilt-up stop control is activated and it cannot be recognized that the tilt-up of the outboard motor 3 has stopped. There is. Therefore, in order to promptly end the tilt-up operation when the tilt-up of the outboard motor 3 is stopped, for example, a warning lamp 42 (LED or the like) of the instruments provided on the instrument panel 7 or a buzzer 9 for warning is provided. It is operated (blinking, etc.) and a stop display is given to the operator (step 2-5).

In any of the tilt-up stop position setting methods, a simple setting operation can prevent the outboard motor 3 from interfering with the hull 2 during the tilt-up operation. Further, since the operator does not need to always visually check the outboard motor 3 during the tilt-up operation, the operability is improved. Also,
In the tilt-up stop position setting method described above, the relative position (angle) between each hull 2 and the outboard motor 3 is recognized in the state in which the tilt angle detector 48 is attached to the ship 1, not the absolute angle from the reference position. Since the tilt angle detector 48 itself does not require high accuracy (tolerance) or high mounting accuracy, and initial adjustment at the time of assembly is unnecessary, cost reduction can be achieved. it can.

Furthermore, the stop position of the outboard motor 3 can be set safely, reliably and with high accuracy and steplessly, and erroneous setting, erroneous operation and erroneous operation can be prevented.

By the way, the power source of the control device 52 is turned on / off by the ignition switch 56 (see FIG. 5) provided in the remote control box 13 arranged on the side of the steering seat 6, for example. Since the control device 52 is configured to perform the tilt-up stop control, a power source is required regardless of whether the ignition switch 56 is ON or OFF.

The outboard motor 3 including the outboard motor 3 according to the present invention is also provided with a PTT switch 47 on the outboard motor 3 so that the outboard motor 3 can also be tilted from the outside of the ship 1. Therefore, in the PTT device 41 according to the present invention, the tilt operation can be performed from the PTT switch 47 of the outboard motor 3 regardless of whether the ignition switch 56 is ON or OFF.
As shown in FIG. 5, when the PTT switch 47 is operated for UP, the PTT switch 47 is pushed to supply power to the control device 52. With this configuration, when the PTT switch 47 is not operated, unnecessary discharge does not occur in the accessories and the control device 52, and the battery 55 does not rise during storage.

On the other hand, the PTT device 41 according to the present invention is
When the outboard motor 3 reaches the tilt-up position, the tilt-up operation is stopped independently of the operation of the tilt-up operator. In addition, the control device 5 of the PTT device 41
No. 2 requires a power source as described above, and a circuit configuration in which stop control cannot be performed unless electric power is input is also conceivable. If the outboard motor 3 cannot stop at the set position, a problem will occur.

Therefore, in the PTT device 41 according to the present invention, as shown in FIG. 5, the control relay 57 is turned on even if the PTT switches 46 and 47 are operated in a state where electric power is not input to the control device 52. Without this, the circuit configuration is set so that tilt-up cannot be performed.

If the tilt-up setting position information is canceled or the stored value is out of the settable range for some reason during the tilt-up operation by the operator, for example, a warning light of the instrument provided on the instrument panel 7 is displayed. It is set to operate (blink, etc.) 42 (LED or the like) and the buzzer 9 for warning to display a warning to the operator. Further, when such a state occurs, it is possible to set the tilt-up operation to be stopped on the spot or stopped at a preset stop position.

Furthermore, the fact that electric power is input to the control device 52 and the control is possible may be transmitted to the operator by means such as the above-mentioned warning lamp 42 or voice.
On the contrary, when the operator performs a tilt-up operation in a state where no electric power is input to the control device 52, a configuration is possible in which the operator is warned by means such as the above-mentioned warning light 42 or voice.

By the way, when changing and resetting the current tilt-up position (angle), for example, if the new position is below the current position, any one of the above-mentioned tilt-up stop position setting methods from the first to fifth It is possible to reset by using. On the other hand, if the new position is above the current position, when using the above-described first and second tilt-up stop position setting methods, it is necessary to cancel the current setting and then reset it.

As a method of canceling the current setting, for example, a cancel switch (not shown) dedicated to canceling may be provided. Also,
Similar to the second tilt-up stop position setting method described above, the second tilt-up stop position setting method may occur because, for example, the ship operator may unknowingly touch the release switch and erroneously release the switch during normal use (operation). Control device 5 as shown in
Condition of combination of signals from each device input to 2 (engine 15 is in a stopped state, tilt-up angle is equal to or greater than a set lower limit value or current set value, switch operation not normally performed)
The current setting may be canceled when the above condition is satisfied.

In the above-described embodiment, the stop control at the time of tilting up is described, but it goes without saying that it can be applied to the stopping work at the time of tilting down.
