Japanese Patent No. 6247704

Because leaning vehicles excel in mobility and convenience, they are used in various running scenes. A leaning vehicle teaching support device is required to output leaning vehicle rider evaluation data indicating evaluation of driving skills unique to leaning vehicles, in which various running scenes are taken into account. When one tries to acquire data regarding a variety of situations such as running environments in order to evaluate driving skills in consideration of various running scenes of the leaning vehicles, an amount of data processed by the leaning vehicle teaching support device is huge, and puts a heavy load on the hardware of the device. Because the hardware resource required by the leaning vehicle teaching support device is increased, the design of the hardware resource is restricted. As a result, the degree of freedom in designing the hardware resource of the leaning vehicle teaching support device is decreased.

An object of the present teaching is to provide a leaning vehicle teaching support device in which the quality of leaning vehicle rider evaluation data is improved while the degree of freedom in designing hardware resource is high.

The present inventors acquired new findings through researches on the quality of leaning vehicle rider evaluation data output by the leaning vehicle teaching support device.
Being different from drivers of vehicles that are not leaning vehicles, a rider of a leaning vehicle may change the traveling direction of the vehicle not only by steering a steering operator but also by moving the gravity center. Furthermore, being different from drivers of vehicles that are not leaning vehicles, the rider of the leaning vehicle may operate not only a front wheel brake operator but also a rear wheel brake operator, when decelerating the vehicle. As such, leaning vehicles are different from the other types of vehicles in the way of operation by riders. The riders of leaning vehicles are therefore required to have driving skills peculiar to the leaning vehicles.
The leaning vehicle teaching assist system of Patent Literature 1 outputs leaning vehicle rider evaluation data of turning periods that are the same running scenes based on the same operation by the riders, in a comparable manner. As the leaning vehicle rider evaluation data of turning periods that are the same running scenes based on the same operation by the riders are output in a comparable manner, the quality of the leaning vehicle rider evaluation data indicating evaluation of driving skills of riders is improved.
Meanwhile, through the research on the quality of the leaning vehicle rider evaluation data output by the leaning vehicle teaching support device, the inventors of the subject application found that various running scenes in which a leaning vehicle is used include running scenes in which an operation by the rider significantly influences on an action of the leaning vehicle.
Based on this finding, in order to improve the quality of the leaning vehicle rider evaluation data of the leaning vehicle teaching support device, the present inventors worked out a technical idea different from the technical idea of Patent Literature 1.
This technical idea is to output leaning vehicle rider evaluation data of different running scenes based on different operations in a predetermined course, in a comparable manner. According to the technical idea, as running scenes based on different operations in the predetermined course are regarded as running scenes in which an operation of the rider relatively greatly influences on the action of the leaning vehicle, evaluation of the driving skill of the rider is facilitated.
The inventors of the subject application further studied the technical idea that the leaning vehicle rider evaluation data of different running scenes based on different operations, in which an operation of the rider relatively greatly influences on the action of the leaning vehicle, is output in a comparable manner, and the inventors finally invented a means for achieving the object, which further improves the quality of the leaning vehicle rider evaluation data of evaluation of the driving skill of the rider, without requiring an increase in an amount of acquired running data and an increase in the frequency of running data.

The running scene regarding sudden braking and the running scene regarding avoidance are different running scenes in the predetermined course.

When the running scene regarding sudden braking and the running scene regarding avoidance, which are different running scenes, are combined, actions such as steering and operations performed by the rider and actions of the vehicle in response to the driver’s actions are limited to some degree. On this account, it is possible to narrow down the points of evaluation of the driving skill of the rider, and hence the evaluation of the driving skill of the rider is facilitated.

<Predetermined Course>
In the present teaching and the specification, a predetermined course is a course determined in advance for acquiring running data of a leaning vehicle. The predetermined course is a course dedicated to the acquisition of running data of a leaning vehicle. The predetermined course is provided in, for example, a private property, and does not include public roads. Public roads are roads in public land. The public roads do not include, for example, roads in private properties and parking lots in public land. In the present teaching and the specification, the predetermined course is a course on which a running scene regarding sudden braking and a running scene regarding avoidance can be performed when the rider drives the leaning vehicle on the predetermined course. In the present teaching and the specification, the predetermined course may be a course where a running scene in which the rider uses the acceleration operator can be performed when the rider drives the leaning vehicle on the predetermined course. The running scenes of various types in the present teaching and the specification are running scenes in each of which the rider is required to execute a drill of running in a predetermined condition. In the present teaching and the specification, the predetermined course may include plural paths corresponding to a running scene. In the present teaching and the specification, a path in the predetermined course is not limited to a single path that can be successively run. In the present teaching and the specification, a single course may include plural paths that cannot be successively run. A path of a course may not be completely matched with the running locus of the leaning vehicle.

<Leaning Vehicle Rider Evaluation Data>
In the present teaching and the specification, the leaning vehicle rider evaluation data is data indicating evaluation of the driving skill of a rider who drives a leaning vehicle in the predetermined course. The leaning vehicle rider evaluation data may be generated from running data of various types of running scenes based on reference data of the various types of running scenes. The reference data of the various types of running scenes is generated based on running data of the various types of running scenes in which a rider runs on the predetermined course, plural sets of running data of the various types of running scenes in which riders run on the predetermined course, or plural sets of running data of the various types of running scenes in which a rider runs on the predetermined course plural times. The reference data is acquired in advance. The leaning vehicle rider evaluation data may be binary data indicating, e.g., good or bad, may be data of 5-grade evaluation or 10-grade evaluation, or may be data of points out of 100. In the present teaching and the specification, the leaning vehicle rider evaluation data may be output as data associated with an evaluation target rider who is an evaluation target and drives an evaluation target leaning vehicle which is an evaluation target, or may be output as data associated with an evaluation target rider and an evaluation target leaning vehicle which is driven by the evaluation target rider and is an evaluation target. In the present teaching and the specification, “to output the leaning vehicle rider evaluation data” indicates that, for example, the leaning vehicle rider evaluation data is output from the leaning vehicle teaching support device to a terminal device, a recording medium, or the like by wireless communication or wired communication. To be more specific, for example, the leaning vehicle rider evaluation data is output from the leaning vehicle teaching support device to a terminal device used by a student or a teacher by wireless communication or wired communication. In this case, for example, the leaning vehicle rider evaluation data output from the leaning vehicle teaching support device is displayed on a display of the terminal device. In addition to the above, for example, the leaning vehicle rider evaluation data is output from the leaning vehicle teaching support device to a printer by wireless communication or wired communication. In this case, for example, the leaning vehicle rider evaluation data output from the leaning vehicle teaching support device is printed by the printer. In the present teaching and the specification, “the evaluation data outputting unit outputs plural sets of leaning vehicle rider evaluation data in a comparable manner” indicates, for example, the evaluation data outputting unit outputs plural sets of leaning vehicle rider evaluation data so that the sets of data are lined up on a single screen of a display of the terminal device. Alternatively, for example, the evaluation data outputting unit outputs sets of leaning vehicle rider evaluation data so that the sets of data are printed by a printer to be lined up on a single sheet of paper.

<Running Scene Regarding Sudden Braking>
In the present teaching and the specification, a running scene regarding sudden braking is, for example, a scene in which a leaning vehicle runs in a condition of generating large braking force, e.g., the rider stops the leaning vehicle with the shortest possible distance immediately after a sign is given to the rider. In other words, the running scene regarding sudden braking is a scene in which the leaning vehicle runs and generates relatively large braking force. For example, the running scene regarding sudden braking is a scene in which the rider drives the leaning vehicle so that braking force larger than the braking force generated in normal driving is generated. Examples of such conditions in which large braking force is generated are, for example, a condition in which the rider drives the vehicle at predetermined speed and stops the vehicle with the shortest possible distance in response to a sign, and a condition in which, after the vehicle runs at predetermined speed and passes through a predetermined location, the vehicle stops at another predetermined location. In the present teaching and the specification, the running scene regarding sudden braking is not a scene in which the leaning vehicle runs in a condition in which normal braking force is generated, e.g., in a condition in which the rider drives the vehicle at suitable speed toward a known stop point and decelerates and stops the vehicle.

<Running Scene Regarding Avoidance>
In the present teaching and the specification, a running scene regarding avoidance includes a running scene in which a leaning vehicle in a straight-traveling state avoids an obstacle and then returns to the running in the straight-traveling state and a running scene in which a leaning vehicle in a turning state avoids an obstacle and then returns to running in the turning state. In this scene, the inclination angle of the leaning vehicle before the avoidance of the obstacle may not be identical with the inclination angle after the avoidance of the obstacle. Furthermore, the running scene regarding avoidance includes a running scene in which a leaning vehicle in the straight-traveling state avoids an obstacle and then shifts to the running in the turning state and a running scene in which a leaning vehicle in the turning state avoids an obstacle and then shifts to the running in the straight-traveling state. In the present teaching and the specification, the obstacle may or may not actually hinder the running of a vehicle. The obstacle may be an automobile, truck, or a motorcycle left unmoved on the road surface. The obstacle may be a dummy obstacle. The obstacle in this case is, for example, a plate imitating an automobile or human and provided on the road surface, a pylon identical in size with an automobile or human and provided on the road surface, or a line identical in size with an automobile or human and provided on the road surface. The obstacle may be, for example, an obstacle assumed by a rider. In this case, in response to a sound sign or light sign for the rider, the rider drives the leaning vehicle with the assumption that an obstacle is in front of the rider.

<Running Scene Using Acceleration Operator>
In the present teaching and the specification, a running scene using an acceleration operator includes at least one of a running scene regarding turning immediately after start, a running scene regarding U-turn, a running scene regarding line tracing, a running scene regarding low-speed running, or a running scene regarding running in a straight-traveling state and running in a turning state, and may include a running scene in which a rider uses the acceleration operator, which is different from these running scenes.

<Running Scene Regarding Turning Immediately After Start>
In the present teaching and the specification, a running scene regarding turning immediately after start is a running scene in which a leaning vehicle in a stopped state is inclined at the same time as the start and is caused to turn at a turning angle equal to or larger than 90 degrees, for example.

<Running Scene Regarding U-Turn>
In the present teaching and the specification, a running scene regarding U-turn is a running scene in which a leaning vehicle running in the straight-traveling state turns at a turning angle of, for example, 150 degrees or more and 180 degrees or less with reference to a line formed on the road surface or a pylon provided on the road surface. In the running scene regarding U-turn, the speed when U-turn is performed may or may not be set in advance.

<Running Scene Regarding Line Tracing>
In the present teaching and the specification, a running scene regarding line tracing is a running scene in which a leaning vehicle runs along a line formed on the road surface. The line is formed on the road surface as a line including at least one of a linear line or a curved line, with the assumption that the vehicle runs in at least one of the straight-traveling state or the turning state. The line may be formed solely of a linear line, may be formed solely of a curved line, or may include both a linear line and a curved line.

<Running Scene Regarding Low-Speed Running>
In the present teaching and the specification, a running scene regarding low-speed running is a running scene in which a leaning vehicle runs in a straight-traveling state or a turning state at a low speed at the maximum. The low speed is, for example, 20 km/h, 15 km/h, or 10 km/h. The running scene regarding low-speed running may include running at speed within a range of 10 km/h or higher and 20 km/h or lower. In the running scene regarding low-speed running, the leaning vehicle may run along a line formed on the road surface.

<Running Scene Regarding Running in Straight-Traveling State and Running in Turning State>
In the present teaching and the specification, a running scene regarding running in a straight-traveling state and running in a turning state is a running scene in which a leaning vehicle runs in a predetermined course in which both running in the straight-traveling state and running in the turning state are realized, by using a line formed on the road surface or a pylon provided on the road surface. The running in the turning state may include both right turning of the leaning vehicle and left turning of the leaning vehicle.

<Running Data of Running Scene Regarding First Sudden Braking, Running Data of Running Scene Regarding First Avoidance, Running Data of Running Scene Using First Acceleration Operator, Running Data of Running Scene Regarding Second Sudden Braking, Running Data of Running Scene Regarding Second Avoidance, and Running Data of Running Scene Using Second Acceleration Operator>
In the present teaching and the specification, a phrase “associated with” in “running data of a running scene using a first acceleration operator associated with running data of a running scene regarding first sudden braking” indicates that the running data is used for generating leaning vehicle rider evaluation data which is output by the evaluation data outputting unit in a comparable manner. In other words, “running data of a running scene regarding first sudden braking” and “running data of a running scene regarding first avoidance” are sets of running data that are output by the evaluation data outputting unit in a comparable manner, and are running data of a running scene regarding sudden braking used for generating leaning vehicle rider evaluation data regarding first sudden braking and running data of a running scene regarding avoidance used for generating leaning vehicle rider evaluation data regarding first avoidance. “Running data of a running scene using a first acceleration operator” is running data output by the evaluation data outputting unit to be comparable with the leaning vehicle rider evaluation data regarding the first sudden braking and the leaning vehicle rider evaluation data regarding the first avoidance, and is running data of a running scene using an acceleration operator used for generating leaning vehicle rider evaluation data using a first acceleration operator. The running data of the running scene regarding the first sudden braking, the running data of the running scene regarding the first avoidance, and the running data of the running scene using the first acceleration operator may be sets of running data acquired on the same day, or sets of running data acquired on different days. The definitions of running data of a running scene regarding second sudden braking, running data of a running scene regarding second avoidance, and running data of a running scene using a second acceleration operator are omitted because they are similar to the running data of the running scene regarding the first sudden braking, the running data of the running scene regarding the first avoidance, and the running data of the running scene using the first acceleration operator, respectively. The running data of the running scene regarding the second sudden braking is data acquired by the evaluation target running scene running data acquiring unit after the acquisition of the running data of the running scene regarding the first sudden braking. The running data of the running scene regarding the second sudden braking may be acquired on a different day from or on the same day as the running data of the running scene regarding the first sudden braking. The definitions of the running data of the running scene regarding the second avoidance and the running data of the running scene using the second acceleration operator are also omitted for the same reason.
