Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for recording and reproducing brake operations of two-wheeled vehicles, particularly motorcycles.

[Conventional technology]

The driving operation of a motorcycle is different from that of a four-wheeled vehicle.
The timing of brake operation for the rear and front wheels is required.

On a motorcycle, the brake mechanisms for the front and rear wheels are separate systems, and if the brakes are applied suddenly to only the front wheels while riding, there is a risk of the bike falling over, or in severe cases, causing an accident where the bike rolls forward. For this reason, handling of motorcycle brake operation has become one of the important items in driving lessons at driving schools.

[Problem that the invention seeks to solve]

Brake operation instruction is extremely difficult in motorcycle driving lessons because an instructor cannot ride along with the student.
In fact, in driving schools, a method is adopted in which the motorcycle itself is equipped with multiple colored lights that can be seen from a distance, and by sequentially lighting up the colored lights in relation to the braking operation, it is possible to judge whether the braking operation is good or bad. However, it is almost impossible to judge important factors such as the timing of brake operation relative to the distance to the destination, the strength of the operation force, and whether it is appropriate or not, and in fact, only the timing of the operation is checked. For this reason, trainees have no choice but to repeatedly practice how to operate the brakes on their own, and it takes a long time to master them.

An object of the present invention is to provide a device, particularly in a driving school, that automatically records brake operations performed by a trainee driving a motorcycle, and later reproduces and displays the recorded contents to obtain appropriate instructional materials.

[Means for solving problems]

The present invention provides a means for detecting the brake operating force and traveling speed applied to the front and rear wheel brake mechanisms of a two-wheeled vehicle and converting them into electrical signals, and a brake signal within a certain period of time that is converted into an electrical signal and Means for storing speed signals over time, retaining the stored contents within a certain time period in response to a stop signal from the speedometer, and displaying the signal output of the stored stored contents on the screen in relation to the time axis A control operation recording device for a two-wheeled vehicle, characterized in that the case is equipped with at least a display means, and the case is removably mounted on the body of the two-wheeled vehicle, and the display means is retained. A brake operation recording device for a two-wheeled vehicle, characterized in that it has a function of simultaneously displaying at least two stored contents, a signal output of a first stored contents and a signal output of a second stored contents, on a screen. .

[Effect]

FIG. 2 shows a functional block diagram of the apparatus of the present invention.

The strength of the brake operating force combined with the front wheel brake mechanism F and rear wheel brake mechanism R of the motorcycle is detected separately by detection means 1 and 2, and the traveling speed of the motorcycle is detected from the speedometer PG, and each The detection signal is processed by the signal processing section 3, and each signal is stored and held in the storage section 4 over time by a certain period of time from the time of stopping due to braking, and later, the change in signal output of the stored contents with respect to the time axis is displayed on the display section 5. This screen is displayed on the screen to judge whether the driver's brake operation is good or bad. In particular, by displaying the student's data and the instructor's data obtained from a specific base point on the same road until reaching the target point and stopping on the same screen, the timing of braking operations can be adjusted to speed up the timing of braking operations. By comparing the data in relation to the above, it is possible to judge at a glance whether the trainee's brake operation is good or bad.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 3, the magnitude of the braking force applied to the front wheel brake mechanism F of the motorcycle 6 is detected by a strain gauge 8 installed on the brake lever 7, and the magnitude of the braking force applied to the rear wheel brake mechanism R is detected. is detected by a strain gauge 10 mounted on the brake arm 9. The detection signals are passed through amplifiers 11 and 12, respectively, to a data selector (multiplexer MPX) 13.
Enter. In the embodiment, the MPX 13 uses the input of student data and instructor data, as well as the A series and B series of switching signals thereof. The output signal is converted by an A/D converter (ADC) 14, processed by a microcomputer unit (MPU) 15, and data input signals are written to a random access memory (RAM) 16 for each A series and B series. .

On the other hand, the speed signal obtained from the speedometer PG of the motorcycle is directly input to the MPU 15, which processes the signal and writes the data into the RAM 16.

In the figure, 17 is a graphic display (LCD). Data read from RAM16 for each series,
Alternatively, it has a function to graphically display two series at the same time. 18 in the figure is a start switch,
19 is a mode switch. Power source 20 is obtained from the motorcycle's battery.

Above, MPU15, RAM16, ADC14,
MPX13, etc. are converted into ICs, and the board P and LCD 17 on which these are mounted are housed in the case 21 shown in Fig. 4a and b, and the LED 17 is placed on the top surface of the case 21.
to appear. The case 21 is a box with a lid and has flanges 22 on both sides. As shown in FIG. 1, the case 21 is mounted on the motorcycle carrier 23,
A belt 24 attached to the flange 22 is stretched around the body of the motorcycle 6 and fixed in place. Also,
On one side of the case 21 are a front wheel brake mechanism F, a rear wheel brake mechanism R, and a speedometer, as shown in Figure 4c.
Sockets 25, 26, 27 for signal input from PG
The strain cage 8 and the rear wheel brake mechanism are attached to the brake lever 7 of the front wheel brake mechanism F shown in Fig. 1 by extending the cords _l1 , _l2 , _{l3 of} the plugs connected to each socket. Connect to the strain gauge 10 and speedometer PG attached to the R brake arm 9, respectively. 28 is a power socket. Connect to the motorcycle battery using an extension cord. Note that the lid body 29 that closes the case 21 is connected to the clamp 3.

In the embodiment, recording is started at the same time as the power is turned on by operating the start switch 18,
The speed of the motorcycle and the strength of the brakes applied to the front and rear wheels are recorded moment by moment. In this embodiment, an endless recording method of a semiconductor memory is adopted, and new data is recorded while erasing previous recordings, and for example, recordings within a period of 20 seconds are always retained.

The data required by the present invention is data from when the driver operates the brake mechanism to apply the brakes until the motorcycle comes to a stop. Generally, this time is around 7 seconds, but data recording stops when the motorcycle comes to a stop, and data records for 20 seconds are retained starting from the time the motorcycle comes to a stop.

Data is recorded for both the student and the instructor when the vehicle drives from a predetermined base point to a target point and stops on the same road within the driving school. Recorded data separately or simultaneously
Graphically displayed on LCD 17. An example of the display is shown in FIG. The magnitude of the brake operating force is detected by the magnitude of strain generated in the strain gauges 8 and 10,
A curve of change in traveling speed pg in relation to the brake operation is obtained together with a curve of the operating force f of the front wheel brake and the operating force r of the rear wheel brake.

When applying the brakes, the brake operation on the rear wheel always precedes the brake operation, and the force applied to the brake operation applied to the rear wheel later must bring the motorcycle's traveling speed PG to a stop in a smooth curve. When the curve shown in Figure 5 is the data of the brake operation by the instructor who stopped after reaching the target position from a specific base point, that data and the data obtained by the instructor driving on the same road until the instructor stopped. By displaying the data individually or simultaneously on the LCD 17 and comparing the curves, you can use the instructor's data curve as a model operation to determine at a glance the timing and strength of the brake operation by the student based on the differences in the curves. can. Further, this display data can also be obtained as a detailed hard copy by separately connecting a plotter 34 to the MPU 15.

〔Effect of the invention〕

As described above, the device of the present invention is mounted on the vehicle body, and records the brake operation force within a certain period of time until the vehicle stops due to brake operation in relation to the traveling speed, and after the vehicle stops, the contents of the operation are reproduced on a graphic display. As a result, detailed data on the trainee's brake operation, which was impossible to judge using conventional methods, can be obtained, and appropriate guidance can be provided using the graphical display or hard copy of the data as a material for determining the quality of operability. I can do it. In particular, by directly comparing the student's data with the data from the instructor's model operation, it is possible to not only judge whether the brake operation is good or bad, but also to visually recognize the actual differences. It is possible to provide more detailed guidance on understanding the feeling of brake operation, streamlining driving lessons at driving schools,
In turn, this has the effect of greatly contributing to safe driving.
