[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-wheeled vehicle capable of detecting a bank angle (tilt angle) of a vehicle body, and two-wheeled vehicle driving technical data for collecting driving technical data for improving the driving technique of the two-wheeled vehicle. Regarding the collection system.

2. Description of the Related Art In a motorcycle (motorcycle), there is a case in which a driver is required to improve his or her driving skill, for example, a vehicle runs on a predetermined circuit course such as a circuit (or a driving school). At this time, if it is possible to collect behavior data of the two-wheeled vehicle when traveling on a predetermined circuit course, the driver can grasp his or her skill level by looking at the data after traveling to improve the driving skill. You will be able to connect.

In this case, the behavior data of the two-wheeled vehicle, which is useful for improving the driving technique, includes various factors such as speed, acceleration / deceleration method, brake timing, bank timing and angle.

[0004]

However, although it is considered that the data of speed, acceleration, braking timing, etc. can be easily obtained, in the past, the bank angle of the vehicle body of the motorcycle is detected. There was no means for it.

The present invention has been made in view of the above circumstances, and an object thereof is a two-wheeled vehicle capable of detecting the bank angle of a vehicle body, and a driving including the bank angle for improving the driving technique of the two-wheeled vehicle. It is to provide a driving technical data collection system for motorcycles that enables collection of technical data.

[0006]

A two-wheeled vehicle of the present invention is provided with an acceleration sensor on the vehicle body so that the left and right direction is the detection direction, and the bank angle of the vehicle body is detected based on the detection signal of the acceleration sensor. (The invention of claim 1).

Here, when an acceleration sensor is provided on the vehicle body of the two-wheeled vehicle so that the detection direction is the left-right direction, when the vehicle body of the two-wheeled vehicle is not banked (inclined), the gravitational acceleration only acts directly below the acceleration. The sensor does not detect acceleration. On the other hand, when the vehicle body of the two-wheeled vehicle leans in the left-right direction, the component of the gravitational acceleration acting in the lateral direction of the vehicle body is detected by the acceleration sensor, and the acceleration has a magnitude corresponding to the tilt angle θ. (See FIG. 3). Therefore, according to the invention of claim 1, it is possible to provide a two-wheeled vehicle capable of detecting the bank angle of the vehicle body.

In the two-wheeled vehicle driving technology data collection system of the present invention, an acceleration sensor is provided on the vehicle body so that the left-right direction is the detection direction, and the data of the detection signal of the acceleration sensor or the detection signal is detected. It is characterized in that the data of the bank angle of the vehicle body is recorded in time series by the data collecting means (the invention of claim 2).

According to this, the bank angle of the vehicle body can be detected based on the detection signal of the acceleration sensor, and the data can be recorded in time series when the motorcycle is running. Therefore, according to the invention of claim 2, it is possible to collect the driving technique data including the bank angle for improving the driving technique of the two-wheeled vehicle. For example, it is recorded after the two-wheeled vehicle has traveled a predetermined course. By taking out the data obtained, it becomes possible to know at what timing and at what angle the bank was made during traveling.

In addition to the bank angle data, the data collecting means records the vehicle speed data obtained from the speed detecting means for detecting the traveling speed or the acceleration and the brake signal data in a temporally linked manner. It is also possible (the invention of claim 3). According to this, it is possible to collect behavior data of various motorcycles for use in improving the driving skill, and it becomes more effective for the driver to grasp his / her skill level, which can lead to improvement of the driving skill. .

In this case, it is possible to easily obtain the data of the brake signal for turning on the brake lamp from the brake sensor, which is originally provided in the two-wheeled vehicle, and also easily obtain the vehicle speed data from the vehicle speed sensor as the speed detecting means. However, the speed detecting means may be configured by mounting the second acceleration sensor on the vehicle body so that the front-back direction is the detection direction (the invention of claim 4). This makes it possible to easily obtain data on how the two-wheeled vehicle is accelerated and decelerated.

If the data collected by the data collecting means is recorded in a storage medium that can be attached to and detached from the vehicle body (invention of claim 5), the storage medium in which the data is recorded is taken out after traveling. Then, it becomes easy to move to a personal computer or the like for processing. Further, the data collected by the data collection means can be displayed by the display means (invention of claim 6), whereby the collected data can be provided to the user (driver) in an easy-to-understand form. You can

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS. Figure 2
1 shows an external appearance of a motorcycle body 1 according to the present embodiment, in which a data collection unit 2 (only shown in FIG. 1) which constitutes a driving technology data collection system for a motorcycle according to this embodiment is shown. ) Is attached. Although not shown in detail, the data collecting unit 2 is
Of these, for example, it can be attached to the lower portion of the rear seat 3 or the lower portion of the fuel tank 4.

As shown in FIG. 1, the data collection unit 2 has a CPU (microcomputer) 5 as a control device as a center, and a first acceleration sensor 6 connected thereto.
A second acceleration sensor 7, a brake signal I / F 8 for inputting a brake signal from a brake sensor (not shown) provided in the vehicle body 1 to the CPU 5, a memory 9 as a storage medium in which data is recorded, for example, The operation switch 10 including an on / off switch is incorporated in a case (not shown).

At this time, the first acceleration sensor 6 is
For example, it is composed of a piezoelectric semiconductor acceleration sensor, and as shown schematically in FIG. 2 and FIG.
Is provided so as to be in the left-right direction of the vehicle body 1, so that the acceleration acting in the left-right direction of the vehicle body 1 (a component acting in the lateral direction of the gravitational acceleration g when the vehicle body 1 is tilted, which will be described later) is detected. . The detection signal of the first acceleration sensor 6 is input to the CPU 5.

The second acceleration sensor 7 is also a piezoelectric semiconductor acceleration sensor, and as shown schematically in FIG. 2, it is 90 degrees from the top with respect to the first acceleration sensor 6. Is provided so that the detection direction of the acceleration is the front-back direction of the vehicle body 1, so that the function as a speed detection means for detecting the acceleration (and thus the speed) of the vehicle body 1 during traveling is realized. Has become. The detection signal of the second acceleration sensor 7 is also input to the CPU 5. The second acceleration sensor 7 may be omitted if the signal from the vehicle speed sensor 11 provided on the vehicle body 1 is input to the CPU 5, as indicated by the broken line in FIG.

As described later in the description of the operation, the CP
Due to its software configuration, U5 is designed to operate the vehicle body 1 based on an instruction operation of the operation switch 10 by the user (driver).
Behavior data (driving technology data) during traveling is collected. That is, the CPU 5 is adapted to detect (calculate) the bank angle (tilt angle) θ of the vehicle body 1 based on the detection signal input from the first acceleration sensor 6, and when the vehicle body 1 is running. The data of the bank angle θ is recorded in the memory 9 in time series (for example, every second).

Therefore, the CPU 5 functions as a bank angle detecting means and a data collecting means. At this time, the CPU 5 also

The data of the brake signal input via the brake signal I / F 8 is also linked in time and recorded.

Here, the bank angle θ is detected as follows. That is, when the vehicle body 1 of the two-wheeled vehicle is not banked (inclined), the gravitational acceleration g only acts directly below, so the first acceleration sensor 6 having the detection direction in the left-right direction does not detect acceleration. In contrast,
As shown in FIG. 3, when the vehicle body 1 leans in the left-right direction, the component G of the gravitational acceleration g acting in the lateral direction of the vehicle body 1 is detected by the first acceleration sensor 6 and the acceleration G thereof is also detected. Becomes a size according to the inclination angle θ. That is, since the acceleration G is G = g · cos θ, the bank angle θ can be obtained by the following equation.

In this embodiment, the memory 9 in which the above data is recorded can be taken out and moved to an external personal computer (not shown) to process the data. Specifically, as shown in FIG. 5, the data can be graphed and displayed on a display device (display means) of a personal computer or printed out on paper. At this time, ideal data theoretically required and data that a skilled driver can use as a model for traveling are stored in advance so that they can be compared with the data when actually traveling, It is also possible to accumulate the data of and store them for comparison.

Next, the operation of the above configuration will be described with reference to FIGS. 4 and 5. When a driver of a two-wheeled vehicle wants to collect behavior data when he or she practice-runs on a predetermined circuit course such as a circuit (or a driving school), he / she turns on the operation switch 10 before running. . Then, by the data collection unit 2 (CPU 5),
