Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving state display device for a small vehicle which controls a lamp (indicator light) for displaying a driving state of a vehicle such as a motorcycle training vehicle.

[0002]

2. Description of the Related Art Generally, a motorcycle training vehicle used in a driving school is provided with a display device (lamp lighting display device) for displaying various driving operation conditions so that an instructor can visually recognize the driving operation conditions. ing. Further, when displaying a plurality of types of vehicle speeds, for example, two types of vehicle speeds, two indicator lights are provided and the corresponding vehicle speeds are displayed by the respective lights. Further, the indicator lamp is lit and displayed only in the operating state, and therefore, the disconnection of the lamp cannot be judged unless the traveling state.

In this type of display device, together with a change display lamp indicating a gear shift operation, a brake display lamp indicating a brake operation, and an engine stall display lamp indicating an engine stop (engine stall), two kinds of vehicle speeds are lit and displayed, for example, 30 km / Lamps such as an h display lamp and a 40 km / h display lamp are attached, and each of these display lamps is lit by a separate controller relay (indicator relay).

7 to 9 show examples of controller relays. The controller relay of FIG. 7 is a gear position indicator relay a for a change display lamp, and a gear change switch b for detecting each gear stage (1st speed to 5th speed).
Each of the indicator relays a by turning on / off 1 to b5
1 to a5 are activated. These indicator relays a1 to a
By the operation of 5, the power from the battery B is indicated by the lamp c
1 to c5 are supplied to light.

FIG. 8 shows an engine stop indicator relay d for an engine stall indicator lamp. In FIG.
The output from the igniter e1 to the ignition coil e2 (voltage supply to the spark plug f) (primary ignition signal) detects the engine rotation state and is input to the engine stop indicator relay d. The relay d uses the ignition signal. When an engine stop is detected, the engine stall lamp g is turned on in response to the engine stop. The engine stop indicator relay d is also connected to the power source of the battery B and the ground G.

FIG. 9 shows a speed indicator relay h for a vehicle speed display lamp. In FIG. 9, the magnet sensor rotor i is rotated by the rotation of the crankshaft, and the reed switch j is turned on / off by the rotation of the rotor i (for example, one rotation and four pulses) to detect the engine rotation speed and set the rotation speed. According to (30 km / h, 40 km / h, etc.), the lamp relays ry1 and ry2 are operated to turn on and display the lamps m1 and m2.

[0007]

However, since the indicator relays a, d and h for displaying the respective operating states are provided respectively as described above in the related art, these relays a, d and h are mounted. It has become difficult to secure the space for the two-wheeled vehicle due to the demand for miniaturization of the two-wheeled vehicle, and there is a problem that the cost becomes expensive. Especially in motorcycle training vehicles, various detection devices and display devices are often installed afterwards on a commercial vehicle, and it is required to reduce the detection devices and each device as much as possible in order to reduce the installation work load and installation cost. Was there.

On the other hand, even if the indicator relays a, d, and h are integrated as shown in FIG. 10, the handling is convenient, but the number of indicator lights is the same. That is, as described above, the indicator lights of the respective operating states are the change indicator lamps c1 to c5, the engine stop (engine) indicator lamp g, and the vehicle speed indicator lamp m.
1, m2 and a plurality of indicator lamps such as brake indicator lamps must be mounted on the front and rear of the vehicle. Therefore, the first problem is that many display lamps and their mounting space are required, and the number of parts of the display device and the mounting cost are high.

Further, as described above, since each indicator light is displayed only in the driving state of the vehicle, it is possible to determine that the lamp is broken only after the start of running. Therefore, when a problem such as a lamp disconnection occurs, it is extremely complicated because it is necessary to take measures to solve the problem such as stopping the running and replacing the lamp even after the running is started. There was a second problem.

The present invention has been made to solve the above-mentioned first problem, and it is a gear position of a transmission, a vehicle speed,
(EN) In a device for displaying the engine rotation state, it is possible to reduce the number of vehicle speed indicator lights, reduce the mounting space of the indicator lights, and provide a driving condition display device for a small vehicle that can reduce cost. Let's take the first challenge.

Further, the present invention has been made to solve the above-mentioned second problem, that is, the gear position of the transmission,
In a device that displays a vehicle speed and an engine rotation state, in addition to solving the first problem, it is possible to surely diagnose a defect of an indicator light before the vehicle starts traveling, and to eliminate the problem after the traveling starts. A second object is to provide a driving state display device for a small vehicle that can eliminate the above.

[0012]

In order to solve the first problem, the invention of claim 1 is a gear position indicator lamp for displaying a gear position of a transmission, a vehicle speed indicator lamp for displaying a vehicle speed, And, in a driving state display device for a small vehicle having a rotation state indicator lamp for displaying an engine rotation state, a vehicle speed measuring means for measuring the speed of the vehicle and a measured vehicle speed correspond to a plurality of kinds of set speeds. Based on the determination, the vehicle speed determination means for determining that the vehicle speed is controlled so that the same vehicle speed indicator lamp is turned on differently for each type of the set speed, and the vehicle speed is set to one of the plurality of types of set speeds. And a lighting control means for displaying on the same vehicle speed indicator lamp whether or not the vehicle speed indicator lamp has become compatible.

According to a second aspect of the present invention, the second problem is solved.
According to another aspect of the present invention, there is provided indicator light diagnostic means for illuminating indicator lights including a vehicle speed indicator light in order by turning on the power supply to the operating state display device to perform a diagnostic operation of each indicator light. The driving state display device for a small-sized vehicle described in 1.

According to the invention of claim 1, it is judged that the measured vehicle speed corresponds to a plurality of kinds of set speeds,
Based on this judgment, the lighting state of the same vehicle speed indicator light (for example, one or more, of course, may be two or more) is controlled to be different for each type of the set speed (for example, change of the time interval of lighting / extinction and blinking). , Intensity of light intensity) The same vehicle speed indicating lamp indicates which of the plurality of types of set speeds the vehicle speed corresponds to.

Therefore, the vehicle speed can be set to a plurality of set speeds (for example, the vehicle speed is 30 km or more, or the vehicle speed is 40 km or more) by using only the same vehicle speed indicator light without using a plurality of indicator lights. It is possible to display which one corresponds. Therefore, since at least one lamp may be provided as a vehicle speed indicating lamp for displaying a plurality of kinds of vehicle speeds, the number of indicator lamps to be attached can be reduced. Therefore, the system of the operating state display device can be simplified and the cost can be significantly reduced. Of course, the set speed may be three or more.

According to the second aspect of the present invention, the operating state display device is powered on, for example, immediately after the power is turned on (or after a certain time such as a rising time after the power is turned on. ), The indicator lights including the vehicle speed indicator lights are sequentially turned on to perform the diagnostic operation of each indicator lamp, so that a malfunction such as a disconnection of the lamp can be diagnosed before the vehicle starts traveling. Therefore, it is possible to eliminate the complexity of solving the problem after the start of traveling simply by turning on the power of the vehicle before starting the traveling.

An example of the vehicle speed (30 km / h, 40 km / h) calculated from P) and the engine speed (r / min) is shown.

According to the operation state display device of the above-described embodiment, first, when power is supplied to the indicator relay 34 by turning on the key switch 46, the indicator relay 3 is turned on.
4 is for each lamp 20a1,
20a2, 20a3, 20a4, 20a5, 20b, 2
The lights are sequentially turned on at intervals of 0.5 seconds in the order of 0c. The rider or the diagnostician sees this lighting state and sees each lamp 20a,
It is possible to check (diagnose) whether or not 20b and 20c are disconnected. Of course, at the same time, it can be checked whether the lead wire to the lamp is broken.

Further, it has an engine speed detecting section 22 and a gear position detecting section 24, and the gear is in the first speed to 5th speed.
When the vehicle is in speed, the gear position lamp 20a corresponding to the gear is blinked. The gear position lamp 20a is turned on by grounding the A terminal.

Furthermore, the engine stop display lights up in the mode shown in FIG. That is, when it is determined that the input interval time of the detected engine speed pulse of the engine speed detection unit 22 is equal to or longer than the set time (for example, 1
It is determined that the engine is stopped at 30 msec and 461 r / min). As shown in FIG. 6, the engine stop display lamp 20c is turned on even if the engine is restarted for 4 seconds after the start of the engine stop state. If the stop state continues, the lighting is continued.

Further, based on the engine speed and the gear position detected by the detection units 22 and 24, the vehicle speed calculation unit 26 obtains the vehicle speed, and the vehicle speed display control unit 28 displays the display state according to the obtained vehicle speed. Are displayed differently on the vehicle speed display lamp 20b. For example, as shown in FIG. 5B, the vehicle speed is set to a plurality of different set speeds, for example, 30 km / h or 40 depending on the gear position and the engine speed.
It is judged whether the vehicle speed corresponds to the set speed or not, and the same vehicle speed display lamp 20b is displayed.

Incidentally, for example, the vehicle speed display at the time of neutral (N position, Low) and clutch disengagement (Low) displays the vehicle speed at the number of revolutions before becoming Low. Low
When, the vehicle speed is not displayed even if the rotation speed changes. Also,
The vehicle speed display on the vehicle speed display lamp 20b is lit continuously at a set rotation speed of 30 km / h, provided that the rotation speed of the set rotation speed or more is maintained for 1 second or longer. Also,
The light is turned off when the set rotation speed is -2 km / h, provided that the set rotation speed is lower than 0.5 seconds or more. Furthermore, when it reaches 40 km / h,
The vehicle speed is displayed by blinking the display lamp 20b under the same condition as 30 km / h (a lighting state in which the display lamp 20b is repeatedly turned on and off for a certain time). The light is turned off under the same conditions as 30 km / h. By changing the blinking cycle (changing the time of the entire blinking cycle, or changing the ratio of the lighting time to the extinguishing time, etc.), another vehicle speed display of 1 or more can be made.

Therefore, according to the embodiment, the fact that the vehicle speed corresponds to a plurality of set speeds can be displayed by one indicator light 20b. Therefore, the indicator lights are provided according to each set speed of the vehicle speed as in the conventional case. Compared with the case, it is possible to surely reduce the number of indicator lights. Therefore, the number of parts can be reduced and the mounting space can be saved, which is a great advantage in terms of cost and structure. Of course, the number of vehicle speed indicators is not limited to one, and a plurality of vehicle speed indicators can be provided and all of them can be in the same display state.

Further, only by turning on the key switch 46, the indicator relay 34 changes the lamps 20a1, 20a.
Since it is possible to check (diagnose) the disconnection of 2, 20a3, 20a4, 20a5, 20b, 20c, it becomes possible to reliably diagnose the problem of the disconnection of the indicator lamp before the vehicle starts running, and the problem is solved after the running starts. The complexity of doing can be eliminated.

Further, without providing the vehicle speed detecting section, the engine speed detecting section 22 and the gear position detecting section 24 are provided.
The vehicle speed and gear position can be indicated by the indicator lights 20b, 2
0a can be displayed. Therefore, since the vehicle speed can be detected only by detecting the engine speed and the gear position, the engine speed detector 22 does not have a vehicle speed detector.
The vehicle speed can be displayed on the vehicle speed display lamp 20b, the gear position can be displayed on the gear position lamp 20a, and the engine stop state can be displayed on the engine stop display lamp 20c only by the gear position detection unit 24.
Therefore, the vehicle speed detector is not required, the system is simplified, and the cost can be significantly reduced.

[0036]

As described above, according to the invention of claim 1, in the device for displaying the gear position, the vehicle speed, and the engine rotation state of the transmission, the number of vehicle speed indicators can be reduced, This has the excellent effect of reducing the mounting space for the indicator light and reducing the cost.

According to the second aspect of the present invention, it is possible to surely diagnose the problem of the indicator light before the vehicle starts traveling, and it is possible to eliminate the trouble of eliminating the problem after the vehicle starts traveling. Play.
