Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a race live system for mobile terminals, a race live state display program for mobile terminals, and a race live method for mobile terminals.
[0002]
[Prior art]
As a race live system using a mobile terminal such as a mobile phone and a network such as the Internet, there is already known a system that displays in real time a list of ranks and lap times for each round of vehicles participating in a race.
[0003]
As for yacht races and the like, there is one that mounts a GPS device on a ship itself and traces and displays a wake.
[0004]
Furthermore, if you want to extend the concept of the network to regular TV broadcasts etc., you can install cameras at the important points of the course, such as relaying car races and motorcycle races, to broadcast the movement of the vehicle realistically. Conventionally known.
[0005]
[Problems to be solved by the invention]
However, in the case of a race live system using a mobile terminal such as a mobile phone and a network such as the Internet, the data transfer speed on the network and the processing capacity of the mobile terminal are limited. The display, for example, the above-described ranking for each lap or the character display of the lap time is the limit, and the dynamic actual display is at least difficult at present.
[0006]
In addition, when using a GPS device, in particular, if there are many vehicles to participate in, there is a problem that the procurement of equipment costs a lot and the operation of the race becomes expensive. Furthermore, in the case of a vehicle with a small scale such as a motorcycle, the installation space for the GPS device or the like is not sufficient, and the course used for the race is relatively small. It is doubtful whether progress can be analyzed accurately.
[0007]
On the other hand, in the case of regular TV relay using a camera, there is no particular limitation on the amount of information displayed and the cost can be relatively low, but the installation location of the camera becomes a spot, so the development of the entire race There is a problem that it becomes difficult to grasp.
[0008]
Also, even if you actually go to the race track and watch the race with the naked eye, the whole view of the race track does not enter the field of view, and live broadcasting on the site with speakers etc. is not necessarily enough, There is a demand for using some auxiliary display means to grasp the progress of the race, but a system that can satisfy such demand has not yet been developed.
[0009]
OBJECT OF THE INVENTION
Therefore, the object of the present invention is to eliminate the drawbacks of the prior art, and can be applied to small-scale races such as motorcycles, and dynamically grasps the entire race development at low cost. An object of the present invention is to provide a mobile device race status system, a mobile device race status display program, and a mobile device race status method.
[0010]
[Means for Solving the Problems]
The mobile device race live system of the present invention is a mobile device race live system for displaying on a mobile device the status of a race that is performed by revolving the same course repeatedly using an artificial vehicle, In order to achieve the object, in particular,
Criteria for sampling at least one lap of the course by sampling the movement situation when a vehicle having substantially the same specifications as the vehicle is moved in a test along the course in a race mode in relation to the elapsed time after the start and the movement distance Data measurement means;

Lap time measuring means for measuring the lap time of the vehicle in the actual race,
An outline of the course shape in which the race is performed, the reference lap time for one lap measured by the reference data measuring means, the reference function generated by the reference function generating means, and the start of the race via a communication network And a data transmission means for transmitting the lap time measured by the lap time measurement means during an actual race to the portable terminal via the network for each lap,
The mobile terminal includes
Display control means for displaying an outline of a course shape on a display based on data input via a network;
First moving position predicting means for determining a moving distance of the vehicle for the first one lap for each predetermined period based on the reference function and the elapsed time after the start of the race;
Vehicle movement from the starting point on the second and subsequent laps based on the relationship between the advance and delay of the time between the latest lap time transmitted from the data transmission means and the reference lap time, the reference function, and the elapsed time after passing the start point A second movement position prediction means for obtaining a distance for each predetermined period;
A predicted position display means for displaying the position of the vehicle along the course on the display in correspondence with the movement distance obtained by the first and second movement position prediction means is provided. .
[0011]
First, a vehicle having substantially the same specifications as the vehicle actually used in the race is moved in a test manner along the course in a race mode, and the movement state at that time is measured by the reference data measuring means. The reference data measuring means samples the correspondence relationship between the elapsed time after the start and the moving distance of the vehicle at every predetermined period and stores at least one course. The reference lap time T for one lap is included in the correspondence between the measured elapsed time after the start and the travel distance of the vehicle. ₁ Is included.
The reference function generation means reads the data sampled by the reference data measurement means, and generates a reference function g (T) representing the relationship between the elapsed time after the start and the travel distance of the vehicle based on this data.
During an actual race, the vehicle lap time R is measured by the lap time measuring means. _j Is measured every lap.
The data transmission means constituted by a network communication server or the like includes an outline of a course shape in which a race is performed and a reference lap time T for one lap measured by the reference data measurement means. ₁ And the reference function g (T) generated by the reference function generation means and the start of the race are transmitted to the portable terminal via the communication network. Further, the data transmission means is configured to output a lap time R measured by the lap time measurement means. _j Is transmitted to the portable terminal via the network every lap.
On the other hand, the portable terminal receives the outline of the course shape input from the data transmission means via the network and the reference lap time T ₁ Then, the reference function g (T) is received, and the display control means of the mobile terminal displays the outline of the course shape on the display of the mobile terminal based on the data input from the data transmission means via the network.
The first movement position predicting means provided in the portable terminal receives an elapsed time T after the start of the race in response to the start of the race input from the data transmitting means via the network. _j Measurement of the reference function g (T) and the elapsed time T after the start of the race _j Vehicle travel distance D for the first lap based on _sj Is started every predetermined period. More specifically, the travel distance D _sj Is calculated by adding T to the elapsed time parameter T of the reference function g (T). _j G (T _j ) Is executed.
The predicted position display means is the movement distance D obtained by the first movement position prediction means. _sj The position of the vehicle is displayed along the course on the display. Travel distance D _sj Since the value is obtained and updated every predetermined period, the predicted position of the vehicle is moved and displayed along the course on the display.
In addition, the second movement position prediction means provided in the portable terminal starts operation when the movement display of the first lap by the first movement position prediction means is finished, and the vehicle determines the start point of the second lap. Elapsed time T after passing _j That is, the elapsed time T from the point when the vehicle enters the second lap _j Measurement again, the latest lap time R sent from the data sending means _j And standard lap time T ₁ Relationship between time and delay, and reference function g (T), and elapsed time T after passing the start point _j Based on the travel distance D of the vehicle starting from the starting point of the second lap _cj Is started every predetermined period. More specifically, the travel distance D _cj Is calculated by adding T to the elapsed time parameter T of the reference function g (T). _j × (T ₁ / R _j ) Substituted for g [T _j × (T ₁ / R _j )].
That is, the reference lap time T ₁ Compared to actual lap time R _j When the value of is small, it means that the actual race development is progressing faster than at the time of test movement. _cj The value of is larger than that during the test movement, and conversely, the reference lap time T ₁ Compared to actual lap time R _j When the value of is large, it means that the actual race development is progressing later than at the time of test movement. _cj The value of becomes smaller than that during test movement.
The predicted position display means is the movement distance D obtained by the second movement position prediction means. _cj The position of the vehicle is displayed along the course on the display starting from the starting point. Travel distance D _cj Since the value is obtained and updated every predetermined period, the predicted position of the vehicle is moved and displayed along the course on the display.
In artificial vehicles such as automobiles, motorcycles, ships, airplanes, etc., the fluctuation of the lap time in the circuit course is mainly due to the influence of the external environment such as road surface conditions, temperature and weather, and the throttle when moving on the course Since the selection pattern itself such as work and gear is considered to be determined almost uniquely by the course, if the basic running pattern is corrected according to the fluctuation of the lap time, even if the lap time is different, It is possible to predict and display the actual race development almost accurately. The correction here refers to the compression of the time axis with respect to the elapsed time parameter T of the reference function g (T) indicating the relationship between the elapsed time and the moving distance (T ₁ > R _j ) Or enlargement (T ₁ <R _j ).
The operations of the second movement position predicting means and the predicted position display means after the third lap are the same as those in the second lap described above, but the lap time R _j Is updated every lap, and this new lap time R _j Travel distance D at each lap based on the value of _cj Since the value of is calculated, the lap time R _j Even if the value of fluctuates, it is possible to predict the actual race development almost accurately and display the position of the vehicle at each time point.
As described above, the data to be transmitted from the data transmission means to the portable terminal includes the outline of the course shape transmitted in the initial stage and the reference lap time T ₁ And the reference function g (T) and the lap time R sent every lap _j In addition, the vehicle movement display itself is achieved by a simple arithmetic processing on the portable terminal side. Therefore, it is possible to dynamically grasp the development of the entire race with a reduced amount of data transfer, despite the fact that the race is a live system using a mobile terminal such as a mobile phone and a network such as the Internet. In addition, since it is not necessary to install special equipment on the vehicle itself, it can be applied to a small scale race such as a motorcycle at a low cost.
[0012]
Further, the reference data measuring means samples data for two or more consecutive laps, and the relationship between the elapsed time after the start in the first lap and the moving distance, the reference lap time, and after the start point after the second lap. The relationship between the elapsed time and the moving distance and the reference lap time are individually measured, and the reference function generating means generates the reference function for the first lap representing the relationship between the elapsed time after the start and the moving distance, and the second and subsequent laps. A reference function is individually generated, the first moving position predicting unit obtains a moving distance based on the reference function of the first round, and the second moving position predicting unit performs the first round in the second round. The movement distance is obtained based on the reference lap time of the second lap and the reference function after the second lap, and the movement distance is obtained based on the reference lap time after the second lap and the reference function after the second lap after the third lap. Constitution Rukoto is possible.
[0013]
Usually, at the start of the first lap, the vehicle is accelerated from the zero speed state, and when the vehicle passes the start point of the second lap, the vehicle speed has already reached a high speed. Although there will be a difference, by separately generating the reference function and lap time for the first lap and the reference function and lap time for the second and subsequent laps, it becomes possible to predict and display the race development more precisely. .
When such a configuration is applied, a vehicle having substantially the same specifications as the vehicle that is actually used for the race is moved in the race mode along the course two or more times in succession after the start in the first lap. Relationship between elapsed time and travel distance and reference lap time T ₀ And the relationship between the elapsed time after passing the starting point for the second and subsequent laps and the distance traveled, and the reference lap time T ₁ And are measured individually.
The reference function generation means reads the data sampled by the reference data measurement means, and based on this data, the reference function f (T) and 2 for the first round representing the relationship between the elapsed time after the start and the moving distance of the vehicle The reference function g (T) after the circumference is generated. For the second and subsequent rounds, there is no acceleration from zero speed, and the vehicle moves continuously, so only one type of g (T) is required as the reference function.
During an actual race, the vehicle lap time R is measured by the lap time measuring means. _j Is measured every lap.
The data transmission means constituted by a network communication server or the like includes an outline of a course shape in which a race is performed and a reference lap time T for one lap measured by the reference data measurement means. ₀ , T ₁ And the reference functions f (T) and g (T) generated by the reference function generation means and the start of the race are transmitted to the portable terminal via the communication network. Further, the data transmission means is configured to output a lap time R measured by the lap time measurement means. _j Is transmitted to the portable terminal via the network every lap.
On the other hand, the portable terminal receives the outline of the course shape input from the data transmission means via the network and the reference lap time T ₀ , T ₁ And the reference functions f (T) and g (T) are received, and the display control means of the mobile terminal displays the outline of the course shape on the display of the mobile terminal based on the data input from the data transmission means via the network. indicate.
The first movement position predicting means provided in the portable terminal receives an elapsed time T after the start of the race in response to the start of the race input from the data transmitting means via the network. _j Measurement, and the first lap reference function f (T) and the elapsed time T after the start of the race _j Vehicle travel distance D for the first lap based on _sj Is started every predetermined period. Travel distance D _sj Is calculated by setting the elapsed time parameter T of the reference function f (T) to T _j F (T _j ) Is executed in the same manner as described above.
The predicted position display means is the movement distance D obtained by the first movement position prediction means. _sj The position of the vehicle is displayed along the course on the display. Travel distance D _sj Since the value is obtained and updated every predetermined period, the predicted position of the vehicle is moved and displayed along the course on the display.
In addition, the second movement position prediction means provided in the portable terminal starts operation when the movement display of the first lap by the first movement position prediction means is finished, and the vehicle determines the start point of the second lap. Elapsed time T after passing _j That is, the elapsed time T from the point when the vehicle enters the second lap _j Measurement again, the latest lap time R sent from the data sending means _j (Actual lap time for the first lap) and the reference lap time T for the first lap ₀ The relationship between the time delay and the reference function g (T) after the second lap, and the elapsed time T after passing the start point _j Based on the travel distance D of the vehicle starting from the starting point of the second lap _cj Is started every predetermined period. Travel distance D _cj Is calculated by adding T to the elapsed time parameter T of the reference function g (T). _j × (T ₀ / R _j ) Substituted for g [T _j × (T ₀ / R _j )].
That is, the first lap reference lap time T ₀ Compared to the actual lap time R of the first lap _j When the value of is small, it means that the actual race development is progressing faster than at the time of test movement. _cj The value of is larger than that during test movement, and conversely, the first lap reference lap time T ₀ Compared to the actual lap time R of the first lap _j When the value of is large, it means that the actual race development is progressing later than at the time of test movement. _cj The value of becomes smaller than that during test movement.
The predicted position display means is the movement distance D obtained by the second movement position prediction means. _cj The position of the vehicle is displayed along the course on the display starting from the starting point. Travel distance D _cj Since the value is obtained and updated every predetermined period, the predicted position of the vehicle is moved and displayed along the course on the display.
Further, in the third lap, the second movement position predicting means calculates the elapsed time T after the vehicle passes the starting point on the third lap. _j That is, the elapsed time T based on the time when the vehicle entered the third lap _j Measurement again, the latest lap time R sent from the data sending means _j (Actual lap time for the second lap) and the reference lap time T for the second and subsequent laps ₁ The relationship between the time delay and the reference function g (T) after the second lap, and the elapsed time T after passing the start point _j The travel distance D of the vehicle starting from the starting point of the third lap based on _cj Is started every predetermined period. Travel distance D _cj Is calculated by adding T to the elapsed time parameter T of the reference function g (T). _j × (T ₁ / R _j ) Substituted for g [T _j × (T ₁ / R _j )].
That is, the reference lap time T after the second lap ₁ Compared to the actual lap time R in the second lap _j When the value of is small, it means that the actual race development is progressing faster than at the time of test movement. _cj The value of is larger than that during test movement, and conversely, the reference lap time T for the second and subsequent laps is reversed. ₁ Compared to the actual lap time R in the second lap _j When the value of is large, it means that the actual race development is progressing later than at the time of test movement. _cj The value of becomes smaller than that during test movement.
The predicted position display means is the movement distance D obtained by the second movement position prediction means. _cj The position of the vehicle is displayed along the course on the display starting from the starting point. Travel distance D _cj Since the value is obtained and updated every predetermined period, the predicted position of the vehicle is moved and displayed along the course on the display.
The operations of the second movement position predicting means and the predicted position display means for the fourth and subsequent laps are the same as the operations for the third lap described above. There is no acceleration from zero speed after the third lap, and the actual lap time R after the second lap. _j Are sequentially input, so the reference lap time T for the second and subsequent laps obtained in advance is determined. ₁ Based on this, it is possible to predict and display the race development almost accurately.
[0014]
Further, the data transmission means described above is provided with a correction coefficient transmission function for transmitting a correction coefficient according to the vehicle performance and the operator's skill to the portable terminal together with the reference function, and at least the first movement position prediction means It is desirable to provide a duplicate display avoidance function that corrects the reference function with a correction coefficient to obtain the travel distance for each vehicle.
[0015]
In this way, by using a correction coefficient according to the vehicle performance and the driver's skill, even if the same reference function is used, the race development takes into account the vehicle performance and the driver's skill. Can be predicted and displayed.
For example, a correction coefficient ΔD configured by a multiplier _sj And the reference function f (T) and the elapsed time T after the start of the race _j Based on the above, the moving distance D of the vehicle by the first moving position prediction means _sj Is obtained with respect to the elapsed time parameter T of the reference function f (T). _sj × T _j To correct. In this case, if vehicle performance or pilot skill is better than average, ΔD _sj > 1, assuming that the vehicle's race development is progressing faster than the others, and predicting the vehicle's movement position, and if the vehicle performance or the driver's skill is inferior to the average, ΔD _sj As <1, the moving position of the vehicle is predicted on the assumption that the race development relating to this vehicle is progressing later than others.
Thereby, even if it is a case where the same reference function is used for the prediction of the movement positions of a plurality of vehicles, it is possible to solve the problem that a plurality of vehicles are displayed overlappingly in the first round.
In addition, although it is conceivable to apply the same processing operation to the second movement position prediction means, in the case where the lap time is individually measured for each vehicle in the processing after the second round, This lap time itself includes the reference lap time T ₁ Since the characteristics such as the performance of the vehicle and the skill of the driver are reflected in comparison with the above, correction by the correction coefficient is unnecessary.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a conceptual diagram showing an example of a race live system for a mobile terminal to which the present invention is applied and an outline of a racetrack facility.
Although a motorcycle circuit is described here as an example, a substantially equivalent configuration can be applied to a racetrack for automobiles, a racetrack for boats, a pylon race using a light aircraft, or the like.
[0021]
As shown in FIG. 1, the circuit side equipment includes a measurement reference line vehicle passage measuring means 3 for individually detecting the start point passage of a plurality of motorcycles 2 traveling on the circuit 1, and this measurement reference line vehicle passage. A lap time measuring means 4 for receiving the vehicle passage data from the measuring means 3 and individually measuring the lap time of the motorcycle 2 is provided. The lap time measuring means 4 is further connected with a reference clock (chronometer) 5 for time measurement. Has been. Both are known equipment.
[0022]
The lap time measured by the lap time measuring means 4 and the vehicle passing time data measured by the reference clock 6 are input to the database server 7 via the lap data input device 6, and the database server 7 stores these data in the lap time database 8. Store.
Further, the database server 7 transfers the latest lap time of each motorcycle 2 among the lap times stored in the lap time database 8 to the network communication server 9.
[0023]
The database server 7 is a reference function generation unit in the present embodiment, and the network communication server 9 is a data transmission unit in the present embodiment.
The processing operation of the database server 7 as the reference function generation unit and the network communication server 9 as the data transmission unit will be described in detail later using a flowchart.
[0024]
As shown in FIG. 1, the mobile terminal in the present embodiment is configured by a mobile phone 10.
The mobile phone 10 is connected to a communication network 11 such as the Internet, and receives a lap time and vehicle passage time data from the network communication server 9, a calculation processing microprocessor 13, and A display 14, a built-in clock 15, and a memory 16 such as a ROM and a RAM are provided.
[0025]
Among these, the microprocessor 13 and the memory 16 constitute display control means, first movement position prediction means, second movement position prediction means, and prediction position display means in this embodiment, and achieve these functions. For this purpose, the mobile terminal race status display program is installed in the memory 16 in advance.
The processing operation of the microprocessor 13 as the display control means, the first movement position prediction means, the second movement position prediction means, and the prediction position display means will be described in detail later using a flowchart.
[0026]
Although only one mobile phone 10 is shown in FIG. 1 for the sake of simplicity of explanation, in practice, a large number of mobile phones 10 are connected to the network communication server 9 via the communication network 11 as shown in FIG. It is possible to access
[0027]
Next, the basic operation principle of the present embodiment will be described with reference to FIGS.
[0028]
As described in the section of the conventional technology, the conventional race live system using a communication network dynamically reflects real-time race conditions due to the limited image transfer speed on the network and the processing capacity of mobile devices. There was a drawback that could not be displayed.
In this embodiment, first, in order to reduce the weight of the mobile display data itself distributed on the network, simple numerical values or function data instead of images are used, and further, frequent communication processing is eliminated to reduce communication congestion. In order to solve the problem, the real-time data communication is stopped, and the movement status of the motorcycle 2 is predicted and displayed on the mobile phone 10 (mobile terminal) side based on the data sent from the network communication server 9 every lap. To.
In addition, by correcting the prediction of the movement position using the lap time for each lap, the movement position of each motorcycle 2 can be estimated relatively accurately in real time without performing frequent communication processing. It can be so.
[0029]
FIG. 3 is a diagram schematically showing the relationship between the elapsed time (horizontal axis) and the moving distance (vertical axis) after passing the start position when the motorcycle 2 is run along the same circuit course.
[0030]
In artificial vehicles such as automobiles, motorcycles, ships, airplanes, etc., the fluctuation of the lap time in the circuit course is mainly due to the influence of the external environment such as road surface conditions, temperature and weather, or differences in the skills of the pilots. Therefore, it is considered that the selection pattern itself such as throttle work and gear when moving on the course is determined almost uniquely by the course.
[0031]
Therefore, even if the lap time varies as shown in FIG. 4 due to fluctuations in the external environment such as road surface conditions, temperature and weather, or differences in the skill of the operator, the basic driving pattern according to the fluctuations in the lap time. By applying a correction to, it is possible to predict the actual race development almost accurately. As can be seen from FIG. 4, when the relationship between the elapsed time obtained from the sampling results of the second and subsequent laps and the movement distance is expressed by a reference function g (T) using the elapsed time T as a parameter. If so, the reference lap time T during the test run ₁ Compared to actual lap time R _j When the value of is small, it means that the actual race development progresses faster than during the test run, and conversely, the reference lap time T during the test run ₁ Compared to actual lap time R _j When the value of is large, it means that the actual race development is progressing later than in the test run.
In any case, the reference lap time T during the test run ₁ And actual lap time R _j And the actual elapsed time T after passing the starting point _j Based on the above, the value of the time parameter T of the function g (T) representing the moving distance during the test run is expressed as T = T _j × (T ₁ / R _j ) And g [T _j × (T ₁ / R _j )] Is executed, it is possible to predict the value of the moving distance after passing through the start point.
[0032]
However, in order to predict the movement position at the time of the lap, the calculation process cannot be performed using the lap time at the lap. This is because there is no lap time result at that time. Therefore, the actual lap time R at the previous lap is included in the calculation process. _j And standard lap time T ₁ Will be used.
[0033]
In addition, since the result of the lap time is not output during the first lap, it is not possible to perform arithmetic processing using the actual lap time in any way. Therefore, in this case, the movement position is predicted based only on the reference function.
However, since the acceleration from the state of zero speed is performed in the first round of traveling, the selection pattern such as throttle work and gear does not necessarily match the traveling pattern in the second and subsequent rounds. Therefore, in the present embodiment, the reference function g (T) and the reference lap time T for the second and subsequent laps. ₁ Apart from the reference function f (T) and the reference lap time T for the first round ₀ Is obtained by a test run, and the reference function f (T) and elapsed time T in the first lap _j The movement position is predicted only by
The first lap reference lap time T ₀ Is an unnecessary value for the prediction of the movement position of the first round, but is a value necessary for comparison with the actual lap time of the first round in the prediction of the movement position in the second round. Therefore, strictly speaking, g [T _j × (T ₁ / R _j )]], The movement position is predicted in the third and subsequent rounds, and the prediction calculation formula in the second round is g [T _j × (T ₀ / R _j )〕It turns out that.
[0034]
In addition, when there are a plurality of motorcycles 2 having the same specifications, the reference function f (T) and the elapsed time T in the first lap _j If the movement position is predicted only by the above, there is a possibility that a display that these motorcycles 2 are completely overlapped and moved is performed.
Therefore, in the present embodiment, in order to eliminate such a contradiction, a correction coefficient ΔD that takes into account the skill of the operator. _sj Is used to set the elapsed time parameter T of the reference function f (T) to T = ΔD _sj × T _j Add the correction. ΔD if pilot skill is better than average _sj > 1, assuming that the driver's race progresses faster than the others, predict the moving position of the motorcycle 2, and if the driver's skill is inferior to the average, ΔD _sj <1 is assumed, and the moving position of the motorcycle 2 is predicted on the assumption that the race development of the pilot is progressing later than the others. ΔD _sj As for the value of, the past race performance of the pilots participating in the race is statistically evaluated, and an appropriate value is determined in advance and stored in the database server 7.
[0035]
Hereinafter, with reference to the flowcharts of FIGS. 5 to 8, the substantial processing operation of each unit constituting the race live system for mobile terminals of the present embodiment will be described in detail.
[0036]
First, the processing of the reference data measuring means used when sampling the relationship between the reference elapsed time and the moving distance by test running will be described with reference to FIG. The relationship between the reference elapsed time and the distance traveled can be manually measured and recorded using a stopwatch or the like. Here, however, the drive recorder is similar to a motorcycle 2 whose performance is similar to that used for a race. To collect necessary information. Although not shown, this drive recorder is equipped with an elapsed time measuring timer T for measuring the elapsed time, an odometer D for measuring the mileage, a microprocessor, a nonvolatile memory, and the like. ing. In addition, it is desirable that a pilot who performs a test run has a handling skill substantially equivalent to that of a pilot who participates in an actual race.
[0037]
At the time of test driving, the drive recorder first confirms the start of driving by a signal from a speed sensor or the like (step a1), and a file selection index x ₀ After resetting the value to zero (step a2), the file selection index x ₀ Is again incremented by 1 (step a3). Therefore, the file selection index x ₀ The substantial initial value of is 1.
[0038]
Next, the drive recorder resets and restarts the elapsed time measurement timer T to start measuring the elapsed time after the motorcycle 2 starts running (step a4), and resets the value of the odometer D to zero. The measurement of the travel distance is started (step a5), and further, the value of the address search index i is reset to zero (step a6), and then the value of the address search index i is incremented by 1 again (step a7), and the previous sampling is performed. Time storage register T _p The current value of the elapsed time measuring timer T is stored in (Step a8). Therefore, the substantial initial value of the address search index i is 1, and the previous sampling time storage register T _p The actual initial value of is zero.
[0039]
Next, the drive recorder reads the current value of the elapsed time measurement timer T (step a9), and the value of the elapsed time measurement timer T and the previous sampling time storage register T _p It is determined whether or not the time deviation between these values has reached the sampling period Δt (step a10).
[0040]
If the time deviation does not reach the sampling period Δt, the drive recorder waits as it is, and when this time deviation reaches the sampling period Δt, the current value of the odometer D is read (step a11), and the file selection index x ₀ The relationship between the elapsed time T and the travel distance D is stored at the position of the address i in the sampling data storage file F (1) specified by the value (step a12).
[0041]
Next, the drive recorder determines whether or not a base point signal from the start point has been input, in other words, whether or not the motorcycle 2 has completed one lap (step a13).
This base point signal can be easily generated by a method in which an infrared device or the like is installed on the start line of the circuit 1 and its output is detected by a light receiver on the drive recorder side.
[0042]
If the base point signal is not input, the drive recorder increments the value of the address search index i by 1 every sampling period Δt, repeatedly executes the same processing operation as described above, and passes through the sampling data storage file F (1). The relationship between the time T and the travel distance D is sequentially stored.
[0043]
Then, while such processing is repeatedly executed, when the motorcycle 2 completes the first turn and the base point signal from the measurement reference line vehicle passage measuring means 3 is detected in the processing of step a13, the drive recorder Is the file selection index x ₀ It is determined whether or not the current value has reached 2 (step a14). At this stage, the file selection index x ₀ Since the value of is 1, the determination result in step a14 is false. Therefore, the drive recorder uses the current value of the elapsed time measurement timer T, that is, the lap time value T required for the first round of the lap time as the reference lap time T ₀ (Step a15).
[0044]
Next, the drive recorder reads the file selection index x. ₀ 1 is incremented by 1 (step a3), the elapsed time measuring timer T is reset and restarted to start measuring the elapsed time after passing the starting point in the second lap (step a4), and the odometer D The value is reset again to zero, and measurement of the travel distance from the start point of the second lap is started (step a5). After the value of the address search index i is once reset to zero (step a6), the value of the address search index i is incremented by 1 again (step a7), and the previous sampling time storage register T _p The current value of the elapsed time measuring timer T is stored in (Step a8).
[0045]
Thereafter, the drive recorder repeatedly executes the sampling process in the same manner as described above, and sequentially stores the relationship between the elapsed time T and the travel distance D in the sampling data storage file F (2) for each sampling period Δt.
[0046]
Then, while such processing is repeatedly executed, when the motorcycle 2 completes the second turn and the base point signal from the measurement reference line vehicle passage measuring means 3 is detected in the processing of step a13, the drive recorder Is the file selection index x ₀ It is determined whether or not the current value has reached 2 (step a14).
[0047]
At this stage, the file selection index x ₀ Since the value of 2 is 2, the determination result in step a14 is false, and the drive recorder uses the current value of the elapsed time measurement timer T, that is, the lap time value T required for the second lap, as the reference lap time T. ₁ (Step a16).
[0048]
The data in the sampling data storage file F (1) that stores the relationship between the elapsed time and the travel distance in the test run on the first lap, and the progress in the test run on the second lap that is performed without stopping the motorcycle 2 continuously. The data in the sampling data storage file F (2) that stores the relationship between the time and the travel distance is input to the database server 7 as the reference function generation means.
[0049]
An outline of the reference function generation processing by the database server 7 is shown in the flowchart of FIG.
[0050]
First, the database server 7 stores the data of the sampling data storage files F (1), F (2) and the reference lap time T from the nonvolatile memory of the drive recorder. ₀ , T ₁ Is read (step b1).
[0051]
Next, the database server 7 analyzes the relationship between the elapsed time stored in the sampling data storage file F (1) and the travel distance, and determines the elapsed time T and the travel distance D. _s A reference function f (T) dedicated to the first round representing the relationship between the two is obtained (step b2).
[0052]
The relationship between the elapsed time and the travel distance stored in the sampling data storage file F (1) is as shown in FIG. 3, for example. The simplest method for functionalizing this is the elapsed time and the travel distance. The interval of the elapsed time in which the relationship between and linearly changes is obtained, and D is determined for each interval. _s = F (T) = aT + b is divided into simple increase functions, and the value of the proportionality coefficient a and the value of the piece b are obtained for each section.
[0053]
In order to extract the section of the linear change, the value of the index i indicating the data address is sequentially incremented to obtain the distance deviation between the i-th data and the i + 1-th data, and the distance deviation is i-1th. It is determined whether or not the distance deviation between the i-th data and the i-th data is greatly different, and when data having a large difference in distance deviation is detected, it is determined that the section of the linear change has ended. . Then, an equation of a straight line connecting the first data and the last data of this linear change section, that is, D _s = F (T) = aT + b is obtained.
[0054]
It is also possible to obtain the reference function f (T) more strictly using a Bezier curve or the like.
[0055]
Next, the database server 7 analyzes the relationship between the elapsed time stored in the sampling data storage file F (2) and the travel distance in the same manner as described above, and the elapsed time T and the travel distance D are analyzed. _c A reference function g (T) for the second round representing the relationship between the two is obtained (step b3).
[0056]
In a round race, the running pattern for the second lap and the running pattern for the third and subsequent laps are basically the same, so this reference function g (T) is the same for all round trips after the second lap in the actual race. It can be applied to prediction.
[0057]
The reference functions f (T) and g (T) thus obtained and the reference lap time T ₀ , T ₁ The value of is a correction factor ΔD that takes into account the skills of pilots participating in the race. _sj And data indicating the outline of the course shape (a Bezier curve function or the like) are stored in the database server 7. These data can be freely read out by the network communication server 9.
[0058]
Next, the processing operation of the mobile phone 10 (mobile terminal) and the communication processing with the database server 7 during the race will be described in detail with reference to the flowcharts of FIGS.
Here, as an example, a case where the number of motorcycles 2 participating in the race is n and the number of laps until the end of the race is m laps will be described.
[0059]
First, the user who has the mobile phone 10 accesses the network communication server 9 in advance before the race starts, and the reference functions f (T), g (T) and the reference lap time T described above. ₀ , T ₁ Value and race course data, and a correction factor ΔD that takes into account the skills of each pilot participating in the race _sj The value of (j = 1 to n) and the set value of the access cycle for reading the lap time are downloaded from the network communication server 9 to the memory 16 of the mobile phone 10 (step c1, step c2).
[0060]
In this embodiment, in order to prevent a large number of mobile phones 10 from accessing the network communication server 9 simultaneously during the race to increase the load on the network communication server 9 or to hinder data communication, When the mobile phone 10 accesses the network communication server 9 before the start, the network communication server 9 automatically generates an access cycle for reading the lap time for each mobile phone 10 using a random number, Transfer is performed for each mobile phone 10. The access cycle is the reference lap time T ₀ , T ₁ Is a little longer than the above, and a unique value is set for each mobile phone 10.
[0061]
Next, the microprocessor 13 of the mobile phone 10 turns the lap completion flag E corresponding to each motorcycle 2. ₁ ~ E _n Then, the microprocessor 13 as the display control means displays the course shape on the display 14 of the mobile phone 10 based on the course shape data as shown in FIG. 9 (step c3). Then, the microprocessor 13 enters a standby state where it waits for a race start signal to be input from the network communication server 9 (step c4).
[0062]
As described above, since the owner of the mobile phone 10 always accesses the network communication server 9 before the race starts, the network communication server 9 must store the IP address of each mobile phone 10 at this time. Thus, it is possible to simultaneously transmit the race start signal to all the mobile phones 10 (broadcast).
[0063]
When the race start signal from the network communication server 9 is detected by the mobile phone 10 in the determination process of step c4, the microprocessor 13 sets the lap number storage register x corresponding to each motorcycle 2. ₁ ~ X _n Is initialized to 1 (step c5), and an access cycle measuring timer T for measuring the access cycle for reading the lap time ₀ Is reset and restarted, and the microprocessor 13 as the first movement position predicting means performs an elapsed time measuring timer T corresponding to each motorcycle 2. ₁ ~ T _n The value of is reset and restarted, and measurement of the elapsed time after the start of the race is started (step c6).
[0064]
Next, the microprocessor 13 once initializes the value of the motorcycle specific index j to zero and immediately increments it by 1 (step c7, step c8), and corresponds to the motorcycle 2 specified by the current value of the motorcycle specific index j. Circulation count register x _j (Step c9), it is determined whether or not the value has reached 2, in other words, whether or not the motorcycle 2 specified by the motorcycle specifying index j has entered the second and subsequent laps ( Step c10).
[0065]
Circulation count register x _j If the current value of the motorcycle is less than 2, it means that the motorcycle 2 is traveling on the first lap. Therefore, the microprocessor 13 as the first movement position predicting means determines the current value of the motorcycle specific index j. Motorcycle 2 elapsed time measurement timer T corresponding to _j Current value and correction coefficient ΔD _sj Is read (step c11, step c12) and the elapsed time T _j And correction coefficient ΔD _sj And the mileage D of the motorcycle 2 corresponding to the motorcycle specific index j based on the reference function f (T) dedicated to the first lap downloaded in advance. _sj Is predicted (step c13).
[0066]
The microprocessor 13 then moves the travel distance D _sj It is determined whether or not the present value exceeds the length of one lap of the race course (step c14). And mileage D _sj If the length does not exceed the length of one lap, the microprocessor 13 as the predicted position display means indicates that the distance from the start point of the course display on the display 14 to the marker is the travel distance D _sj The predicted position of the motorcycle 2 corresponding to the current value of the motorcycle specific index j is displayed with a marker on the display 14 (step c15).
[0067]
The predicted position of the motorcycle 2 is displayed on the display 14 with a marker having a simple shape. However, as shown in FIG. 9, the shape of the marker is individually determined according to the value of the motorcycle specific index j. There is no confusion when multiple markers are displayed at the same time.
[0068]
In addition, the predicted position has a correction coefficient ΔD taking into account the skill of the operator. _sj Therefore, even if the performance of the motorcycle 2 is the same, it is not displayed repeatedly unless the operator's skill is the same (duplicate display avoidance function).
[0069]
Next, the microprocessor 13 determines whether or not the current value of the motorcycle specific index j has reached the total number n of motorcycles participating in the race (step c18).
[0070]
If the current value of the motorcycle specific index j does not reach the total number n of motorcycles, the microprocessor 13 serving as the first movement position predicting means and the predicted position display means moves again to the process of step c8 and returns to the motorcycle specific index j. 1 is incremented, and the same processing as described above is repeatedly executed, so that the current position of the motorcycle 2 corresponding to the newly incremented motorcycle specific index j is predicted and displayed on the display 14 with a marker. To do.
[0071]
In this way, the current positions of all motorcycles 2 participating in the race are predicted, and each position is displayed on the display 14 by the marker.
[0072]
If the display is complicated, only the motorcycle 2 that is of interest may be selected and displayed. When such a configuration is applied, the value of the motorcycle identification index j corresponding to the motorcycle 2 that is interested is registered in the memory 16 in advance, and the motorcycle identification is performed between the process of step c14 and the process of step c15. A determination process for determining whether or not the current value of the index j is registered in the memory 16 is inserted. If the current value of the motorcycle specific index j is registered in the memory 16, the process of step c 15 is performed in the same manner as described above. The process is executed, and if it is not registered, the process of step c15 is skipped.
[0073]
When the current position prediction process and display process for all the motorcycles 2 participating in the race are finished and the current value of the motorcycle specific index j has reached the total number n of motorcycles, it is confirmed by the determination process in step c18. The microprocessor 13 again initializes the value of the motorcycle specific index j (step c7), repeats the same processing as described above, and predicts the current position for all motorcycles 2 participating in the race. Execute the display.
[0074]
Also during this time elapsed timer T ₁ ~ T _n Value gradually increases, and the estimated mileage D of each motorcycle 2 _sj Since the value of gradually increases, each marker is moved and displayed as if it were an actual race development.
[0075]
And while such processing is repeatedly executed, the predicted travel distance D of any motorcycle 2 _sj When it is confirmed by the determination process in step c14 that the value of has reached the length of one lap of the course, the microprocessor 13 sets the lap number storage register x corresponding to the motorcycle 2. _j In short, the lap number storage register x corresponding to the current value of the motorcycle specific index j _j Is incremented by 1 and the fact that this motorcycle 2 has entered the second lap is stored (step c16).
[0076]
Next, the microprocessor 13 serving as the second movement position predicting means performs an elapsed time measuring timer T corresponding to the motorcycle 2. _j Is reset and restarted, and the measurement of the elapsed time after passing the starting point in the second round is started (step c17).
[0077]
Thus, the lap count register x _j For the motorcycle 2 having a value of 2 or more, since the determination result of step c10 described above becomes true, the prediction of the movement position by the second movement position prediction means is started.
[0078]
Therefore, when the determination result in step c10 is true and it is confirmed that the motorcycle 2 passes the starting point after the second or third lap, the microprocessor 13 first starts the access cycle measurement timer T. ₀ It is determined whether or not the current value has reached the access cycle specific to the mobile phone 10 (step c19).
[0079]
Access cycle measurement timer T ₀ Mobile phone 10 accesses network communication server 9 via communication network 11 and the latest lap time R of each motorcycle 2 is reached. ₁ ~ R _n And each latest ranking A ₁ ~ A _n Is stored in the memory 16 and the information is displayed on the display 14 as shown in FIG. 9 (step c20), and then the access cycle measurement timer T is displayed. ₀ Is restarted (step c21).
[0080]
These processes are the access cycle measurement timer T ₀ Is repeatedly executed at predetermined intervals based on the measured values of the mobile phone 10, but the cycle is individually set for each mobile phone 10 using a random number. There is no problem of excessive load or trouble in communication.
[0081]
In this embodiment, the network communication server 9 generates an access cycle for each mobile phone 10 and transfers it to the mobile phone 10. However, the mobile phone 10 itself is randomized by the calculation function of its own microprocessor 13. It is also possible to configure to generate and set an access cycle.
[0082]
Next, the microprocessor 13 turns the lap completion flag E corresponding to the current value of the motorcycle specific index j. _J Is set, that is, it is determined whether or not the racing run of the motorcycle 2 corresponding to the current value of the motorcycle specific index j has ended (step c22).
[0083]
Cycle completion flag E _J If is not set, it means that the racing run of the motorcycle 2 corresponding to the current value of the motorcycle specific index j has not ended. Therefore, the microprocessor 13 sets the motorcycle 2 corresponding to the current value of the motorcycle specific index j. Elapsed time measurement timer T _j (Step c23), and the latest lap time R of the motorcycle 2 corresponding to the current value of the motorcycle specific index j. _j Is stored in the memory 16 (step c24).
[0084]
As described above, the access cycle for reading the lap time of the mobile phone 10 to the network communication server 9 is the reference lap time T ₀ , T ₁ This is because the data relating to the lap time of the first round may not be read yet at this stage.
[0085]
Therefore, if the determination result in step c24 is false, that is, the latest lap time R of the motorcycle 2 corresponding to the current value of the motorcycle specific index j. _j Is determined not to be stored in the memory 16, the microprocessor 13 as the second movement position predicting means determines the correction coefficient ΔD. _sj Value is read (step c25) and the elapsed time T _j And correction coefficient ΔD _sj Based on the reference function g (T) after the second lap downloaded in advance, the travel distance D from the start point of the second lap of the motorcycle 2 corresponding to the motorcycle specific index j _cj Is predicted (step c26).
[0086]
Thus, there is no data on the lap time of the first lap of the motorcycle 2, and the actual lap time of the first lap and the reference lap time T ₀ If the movement position cannot be predicted using the comparison with _j And correction coefficient ΔD _sj In addition, the movement position is predicted using only the reference function g (T) after the second round. In this case, the basic processing is the same as the prediction processing for the first round, but the content of the reference function used for prediction is different.
[0087]
On the other hand, the latest lap time R of the motorcycle 2 corresponding to the current value of the motorcycle specific index j _j Is stored in the memory 16, the microprocessor 13 as the second movement position predicting unit further selects the lap number storage register x corresponding to the motorcycle 2. _j Whether or not the value of the motorcycle exceeds 2, in other words, whether the motorcycle 2 corresponding to the current value of the motorcycle specific index j is going around the second lap or going around the third lap and thereafter (Step c27).
[0088]
When the motorcycle 2 goes around the second lap, the latest lap time currently stored in the memory 16, that is, the first lap time and the reference lap time T ₀ And the progress and delay of the race development should be evaluated, and if the motorcycle 2 is going around the third and subsequent laps, the latest lap time currently stored in the memory 16, that is, Lap time and reference lap time T after the second lap ₁ This is because the progress and delay of the race development must be evaluated by comparing with the above.
[0089]
Therefore, if the determination result in step c27 is false, that is, if it is determined that the motorcycle 2 corresponding to the current value of the motorcycle specific index j is circling the second lap, the second movement position The microprocessor 13 as the predicting means has an elapsed time T _j And the reference function g (T) and the reference lap time T after the second lap downloaded in advance ₀ And the actual lap time R of the first lap _j Based on the mileage D from the starting point of the second lap of the motorcycle 2 corresponding to the motorcycle specific index j _cj Is predicted (step c28).
[0090]
In this case, the reference lap time T ₀ And the actual lap time R of the first lap _j Relationship with, that is, T ₀ / R _j Since the relative value of the superiority and inferiority between the skill of the pilot maneuvering the motorcycle 2 and the skill of the pilot driver during the standard test driving is clarified by the value of _sj Correction of the predicted position by is not necessary.
[0091]
In addition, when the determination result of step c27 is true, that is, when it is determined that the motorcycle 2 corresponding to the current value of the motorcycle specific index j is circling after the third lap, the second movement The microprocessor 13 as the position predicting means _j And the reference function g (T) and the reference lap time T after the second lap downloaded in advance ₁ And last actual lap time R _j Based on the mileage D from the starting point after the third lap of the motorcycle 2 corresponding to the motorcycle specific index j _cj Is predicted (step c29).
[0092]
In this case as well, the reference lap time T ₁ And last actual lap time R _j Relationship with, that is, T ₁ / R _j Since the relative value of the superiority and inferiority between the skill of the pilot maneuvering the motorcycle 2 and the skill of the pilot driver during the standard test driving is clarified by the value of _sj Correction of the predicted position by is not necessary.
[0093]
The microprocessor 13 then moves the travel distance D _cj It is determined whether or not the current value exceeds the length of one lap of the race course (step c30).
[0094]
And mileage D _cj If the length does not exceed the length of one lap, the microprocessor 13 as the predicted position display means indicates that the distance from the start point of the course display on the display 14 to the marker is the travel distance D _cj The predicted position of the motorcycle 2 corresponding to the current value of the motorcycle specific index j is displayed with a marker on the display 14 (step c31).
[0095]
The predicted position includes the last lap time R of each motorcycle 2 itself. _j And standard lap time T ₁ Or T ₀ As a result of the comparison, the correction is made in consideration of the skill of the pilot, so even if the performance of the motorcycle 2 is the same, the marker will be displayed repeatedly unless the skill of the pilot is the same. Absent.
[0096]
Next, the microprocessor 13 determines whether or not the current value of the motorcycle specific index j has reached the total number n of motorcycles participating in the race (step c37).
[0097]
If the current value of the motorcycle specific index j does not reach the total number n of motorcycles, the microprocessor 13 as the second movement position predicting means and the predicted position display means moves again to the process of step c8 and enters the motorcycle specific index j. 1 is incremented, and the same processing as described above is repeatedly executed, so that the current position of the motorcycle 2 corresponding to the newly incremented motorcycle specific index j is predicted and displayed on the display 14 with a marker. To do.
[0098]
In this way, the current positions of all motorcycles 2 participating in the race are predicted, and each position is displayed on the display 14 by the marker.
[0099]
When only the motorcycle 2 of interest is selected and displayed, it is determined whether or not the current value of the motorcycle specific index j is registered in the memory 16 between the process of step c30 and the process of step c31. A determination process for determination is inserted, and if the current value of the motorcycle specific index j is registered in the memory 16, the process of step c31 is executed in the same manner as described above. If it is not registered, step c31 is performed. This process is configured to be skipped.
[0100]
When the current position prediction process and display process for all motorcycles 2 participating in the race are finished and the current value of the motorcycle specific index j has reached the total number n of motorcycles, it is confirmed by the determination process in step c37. The microprocessor 13 sets the lap completion flag E corresponding to each motorcycle 2. ₁ ~ E _n It is determined whether or not all of these are set, in other words, whether or not the race has been completed (step c38).
[0101]
And the lap completion flag E ₁ ~ E _n If any one of the reset states is maintained, the microprocessor 13 again initializes the value of the motorcycle specific index j (step c7), and then repeatedly executes the same processing as described above to execute the race. The current position prediction and display for all motorcycles 2 participating in the are executed.
[0102]
Also during this time elapsed timer T ₁ ~ T _n Value gradually increases, and the estimated mileage D of each motorcycle 2 _cj Since the value of gradually increases, the marker of each motorcycle 2 is moved and displayed as if it were an actual race development.
[0103]
And while such processing is repeatedly executed, the predicted travel distance D of any motorcycle 2 _cj When it is confirmed by the determination process in step c30 that the value of has reached the length of one lap of the course, the microprocessor 13 sets the lap number storage register x corresponding to the motorcycle 2. _j In short, the lap number storage register x corresponding to the current value of the motorcycle specific index j _j Is incremented by 1, and the fact that this motorcycle 2 has entered the next lap is stored (step c32).
[0104]
Next, the microprocessor 13 uses the lap count storage register x. _j It is determined whether or not the current value of the vehicle exceeds the number m of laps of the entire race, that is, whether or not the motorcycle 2 corresponding to the current value of the motorcycle specific index j has already circulated the race course at least m times (step) c33).
[0105]
If m or more laps are not performed, the microprocessor 13 as the second movement position predicting means determines that the elapsed time measuring timer T corresponding to the motorcycle 2 _j Is reset and restarted, and the measurement of the elapsed time after passing through the start point of the next round is started again (step c34).
[0106]
If it is determined that m or more laps are being performed, this means that the motorcycle 2 has finished racing, and the microprocessor 13 sets the current value of the motorcycle specific index j. Based on the elapsed time measuring timer T corresponding to the motorcycle 2 _j Is reset to stop the operation (step c35), and the lap completion flag E corresponding to the motorcycle 2 is further determined based on the current value of the motorcycle specific index j. _J Is set (step c36).
[0107]
Cycle completion flag E _J Since the process after step c23 is not executed for the motorcycle 2 to which is set (see the determination process in step c22), the marker display on the display 14 disappears in order from the motorcycle 2 that has finished the race. .
[0108]
In addition, when a motorcycle 2 that has dropped out of the race is detected on the way, a signal is sent from the network communication server 9 to the mobile phone 10, and the lap completion flag E of the corresponding motorcycle 2 is processed by the microprocessor 13 side. _J Can be forcibly set, the marker display of the motorcycle 2 that has withdrawn from the race can be erased from the display 14.
[0109]
Finally, all motorcycles 2 have traveled the course more than m times, and the lap completion flag E ₁ ~ E _n When all of the above are set, the determination result in step c38 becomes true, and the race-status display by the mobile phone 10 ends.
[0110]
In the above, the contents of the mobile terminal race live state system to which the mobile terminal race live state display method of the present invention is applied and the substantial mobile terminal race live state display program have been described in detail by taking one embodiment as an example.
Next, some modifications will be briefly described.
[0111]
First, since the mobile phone 10 is provided with a speaker, a vibrator for detecting incoming calls, etc., using these equipment, the user can confirm that a specific motorcycle 2 has passed the attention position on the course. Is possible.
[0112]
In that case, the user instructs the microprocessor 13 to specify the value of the motorcycle specific index j of the motorcycle 2 that he / she is paying attention to, and the distance S from the start point to the target position on the course. The microprocessor 13 stores these values in the memory 16 and moves the distance D. _cj And travel distance D _sj The value of the register for calculating is sequentially monitored, and when the value falls within the range of S ± α (α is a set value), the speaker or vibrator is driven.
[0113]
For example, if the value of the distance S is set to zero, it can be confirmed (predicted) that the specific motorcycle 2 has passed the start point. In addition, when the user is watching the race around the course, the value on the course corresponding to the user's position is input as the distance S, so that the specific motorcycle 2 comes close to him / her. Can be confirmed (predicted).
[0114]
The specification of the motorcycle specific index j and the distance S can be performed by numerical input using the numeric keypad of the mobile phone 10, so that the mobile phone 10 need not be modified at all.
[0115]
Furthermore, the engine sound can be reproduced using the speaker of the mobile phone 10.
[0116]
As described above, the selection state of the gear is considered to be determined almost uniquely depending on each place on the course, so that the engine sound can be reproduced as long as the traveling speed is known. When a Bezier curve or the like is used as the reference functions f (T) and g (T), the function is differentiated, more specifically, the moving distance D obtained in the current processing cycle. _cj Or D _sj Travel distance D obtained in the previous processing cycle _cj Or D _sj The current speed is obtained by subtracting and dividing by the calculation cycle, and the gear selection status is known from the moving position on the course, so the engine speed is calculated based on the current speed and the gear selection status. The speaker can be driven at a frequency commensurate with the engine speed.
In addition, when the elapsed time is divided into sections and the simple increase function for each section is used as a reference function, the movement speed for each section is basically constant. The engine speed is calculated on the basis of the selection status, and the speaker is driven.

【The invention's effect】
The mobile device race live system, the mobile device race live display program, and the mobile device race live state display method according to the present invention have a vehicle having substantially the same specifications as that used for a race, moved in a test manner along the course in a race mode. Measure the movement situation at the time and generate a reference function that represents the relationship between the elapsed time after the start and the movement distance, and communicate the reference lap time and reference function measured in the test movement from the data transmission means during the actual race It is transmitted to the mobile terminal via the network and the actual lap time is transmitted to the mobile terminal every lap, and the relationship between the reference function and the elapsed time or between the latest lap time and the reference lap time is determined by processing on the mobile terminal side. Based on the relationship between the time advance and delay of the vehicle, the reference function, and the elapsed time, the movement position of the vehicle is predicted and displayed every predetermined period. Therefore, only a small amount of communication data, specifically, the transmission process of the reference lap time and the reference function performed only once, and the transmission process of the lap time for each lap, can be used to determine the actual race development situation. The mobile terminal can be moved and displayed with an accurate prediction.
Therefore, even in the case of a race live system using a mobile terminal such as a mobile phone and a network such as the Internet, a dynamic race can be performed without being restricted by data transfer speed and data transfer amount on the network. It is possible to reliably carry out the actual status display.
In addition, since there is no need to install special equipment such as GPS devices on the vehicle used for the race, it is possible to display the actual situation at low cost, and to display the actual situation of the race such as motorcycles that do not have enough space to install the equipment. It is also suitable for preventing vehicle speed reduction due to over-equipment.
Moreover, it is possible to easily grasp the development of the entire race by the display on the display, especially when a mobile phone is used as a mobile terminal, it is very easy to carry the terminal and limit the field of view. It can also be used conveniently when watching a race on a racetrack where the vehicle is approaching and looking at the course.
[0118]
Furthermore, a reference function to be used for predicting the movement position of the first round in order to correspond to the round movement of the first round including the acceleration process from zero speed and the round movement after the second round in which the initial speed itself is increased. And a reference function to be used for predicting the movement position for the second and subsequent laps, and predicting the movement position of the vehicle by selectively using one of the reference functions according to the actual race circumstance Thus, it is possible to predict the movement position with high accuracy.
[0119]
In addition, since the calculation function of the reference function is executed using the correction coefficient according to the performance of the vehicle and the skill of the driver, it is possible to use multiple vehicles with the same specifications participating in the race at the same time. Even if it exists, the movement prediction position of a some vehicle does not overlap darkly, and realistic prediction display can be performed.
