Description

  The present invention relates to a drift scoring system for scoring in a drift game that is a kind of automobile competition.

Unlike the racing competition, where drift competition is simply a competition, the beauty of driving and the level of driving skills are evaluated. Beautiful drift driving impresses the viewer. Because drifting technology and beauty are largely related to human sensitivity, unlike time and maximum speed, it is difficult to quantify. For this reason, in the past, the judges looked at the competitors' runs, evaluated their skills and beauty, and scored.
Patent Document 1 describes a system for scoring drift based on a running line, speed, and drift angle in a drive game machine.

JP 2007-37796 A

The scoring by the judges is subject to the subjectivity of the judges, so there may be blurring in the evaluation, and the athlete may be dissatisfied with the scoring results. For this reason, a system capable of more objective scoring is desired.
The scoring system described in Patent Document 1 does not necessarily obtain a high scoring with beautiful running as seen by the human eye, and cannot accurately evaluate drift technology and beauty.
An object of the present invention is to objectively and accurately evaluate the beauty of drift and the height of traveling technology, and to score them.

The drift scoring system according to the present invention is an evaluation value for calculating two or more evaluation values for each section obtained by dividing the drift competition course, based on running data representing a running situation in which the drift racing vehicle has run on the drift competition course. For each section, a total evaluation value calculation unit that calculates a product of the evaluation values calculated by the evaluation value calculation unit for each section and sets the total evaluation value of the drift racing vehicle, and the total evaluation value calculation unit includes: A drift scoring system comprising: a total score calculated for each section is converted into a section score by a predetermined monotonically increasing function, and a score calculation unit that calculates the score of the drift racing vehicle by summing the converted section scores The evaluation value calculated by the evaluation value calculation unit is obtained by dividing the maximum value of the speed of the drift racing vehicle by a predetermined reference value and calculating the calculated quotient. A maximum speed evaluation value that is a value raised to an exponent, an average speed evaluation value that is a value obtained by dividing the average value of the speed of the drift racing vehicle by a predetermined reference value, and the calculated quotient raised to a power of a predetermined index; A maximum angle evaluation value that is a value obtained by dividing the maximum drift angle of the drift racing vehicle by a predetermined reference value and raising the calculated quotient to a power of a predetermined index, and an average value of the drift angle of the drift racing vehicle are predetermined. The average angle evaluation value, which is a value obtained by dividing the calculated quotient by a predetermined index, and the maximum value of the drift angle change rate of the drift racing vehicle are divided by the predetermined reference value. Divide the maximum angle change rate evaluation value, which is a value obtained by raising the quotient to a predetermined index, and the average value of the drift angle change rate of the drift racing vehicle by a predetermined reference value, and calculate the calculated quotient to the power of the predetermined index And the average angle change rate evaluation value The maximum lateral acceleration change rate evaluation value, which is a value obtained by dividing the maximum value of the lateral acceleration change rate of the drift racing vehicle by a predetermined reference value and raising the calculated quotient to a power of a predetermined index, and the lateral acceleration of the drift racing vehicle The average lateral acceleration change rate evaluation value, which is a value obtained by dividing the average value of the change rate by a predetermined reference value and raising the calculated quotient to a power of a predetermined index, and the maximum value of the change rate of the vertical acceleration of the drift racing vehicle Is divided by a predetermined reference value, and a maximum vertical acceleration change rate evaluation value that is a value obtained by raising the calculated quotient to a power of a predetermined index and an average value of the change rate of the vertical acceleration of the drift racing vehicle by a predetermined reference value. Dividing the calculated quotient to the power of a predetermined index and dividing the average longitudinal acceleration change rate evaluation value and the section time of the drift racing vehicle by a predetermined reference value, the calculated quotient is raised to a power of the predetermined index The section time evaluation value that is That's it.
The comprehensive evaluation value calculation unit preferably sets the comprehensive evaluation value to a predetermined value when the evaluation value calculated by the evaluation value calculation unit does not satisfy a predetermined condition.
In the drift scoring system, each section of the drift competition course is divided into a swing section that is a straight line part before the curve, a drift section that is a curve part in which the bending direction does not change, and a curve part in which the bending direction changes. And the evaluation value calculation unit, when the section is a swinging section or a swinging section, the average speed evaluation value, the maximum angle change rate evaluation value, The average lateral acceleration change rate evaluation value is calculated, and when the section is a drift section, the average speed evaluation value, the average angle evaluation value, and the average angle change rate evaluation value are calculated, When the section is a swing-out section or a swing-back section, the comprehensive evaluation value calculation unit includes the average speed evaluation value, the maximum angle change rate evaluation value, and the average lateral acceleration change rate evaluation value. The product is calculated as the overall evaluation value of the drift racing vehicle, and when the section is a drift section, the product of the average speed evaluation value, the average angle evaluation value, and the average angle change rate evaluation value. Is preferably used as the overall evaluation value of the drift racing vehicle.
Preferably, the score calculation unit calculates a maximum speed point based on the maximum speed evaluation value, and adds the maximum speed point to the total of the section scores to obtain a score of the drift racing vehicle.
The drift scoring system includes a section determination unit that determines which section the drift racing vehicle is in, and a maximum value and an average of the speed of the drift racing vehicle in each section based on a result determined by the section determination unit. Value, maximum and average values of drift angle, maximum and average values of change rate of drift angle, maximum and average values of change rate of lateral acceleration, maximum and average values of change rate of longitudinal acceleration, and interval A data calculation unit that calculates at least one of the times and sets the travel data, and the evaluation value calculation unit calculates the evaluation value based on a value calculated by the data calculation unit. preferable.
The drift scoring system is mounted on the drift racing vehicle, measures a traveling state of the drift racing vehicle, and transmits the traveling data, and receives the traveling data transmitted by the traveling state measuring device. A reception device, and the travel state measurement device includes the section determination unit, the data calculation unit, and a transmission unit that transmits the travel data calculated by the data calculation unit, and the evaluation value calculation unit Preferably, the evaluation value is calculated based on travel data received by the receiving device.
The drift scoring system is configured such that, for each of a plurality of drift competition courses, a reference value storage unit that stores a reference value used by the evaluation value calculation unit to calculate an evaluation value, and the drift racing vehicle travels based on the travel data. A course determination unit that determines the drift competition course, and the evaluation value calculation unit uses the reference value stored in the reference value storage unit for the drift competition course determined by the course determination unit. It is preferable to calculate the value.

According to the drift scoring system according to the present invention, since the product of two or more evaluation values is calculated as the overall evaluation value of the drift racing vehicle, a high score cannot be obtained if any evaluation value is low, A high score can be given to a well-balanced run in all respects. This makes it possible to accurately evaluate the beauty of drift. Each evaluation value includes maximum speed, average speed, maximum drift angle, average drift angle, maximum drift angle change rate, average drift angle change rate, maximum lateral acceleration, average lateral acceleration, maximum vertical acceleration, average vertical acceleration, section time, etc. Since it is calculated based on values that can be measured objectively, it is possible to objectively evaluate the beauty of drift and the height of running technology.
By dividing the course into a plurality of sections and calculating a comprehensive evaluation value for each section, the beauty of drift can be objectively and accurately evaluated for each section that requires different driving techniques. By converting the total evaluation value calculated for each section into a section score and totaling it, it is possible to comprehensively evaluate the running of the entire course.
When the predetermined condition is not satisfied, the total evaluation value in the section is set to a predetermined value, so that the evaluation can be correctly performed even when the drift racing vehicle does not deserve evaluation because of spinning.
In the swing-out section and the swing-back section, fast speed and sharp swinging / backing are required. A total evaluation value is calculated based on the average speed evaluation value related to the speed of speed, the maximum angle change rate evaluation value and the average lateral acceleration change rate evaluation value which are values related to the sharpness of swinging / backing back. Therefore, a high score can be given with respect to the driving | running | working which demonstrated the driving | running technique requested | required in a swing area / backward section. In particular, it is possible to accurately evaluate the beauty of drift running by evaluating the sharpness of the swinging / returning together with the average lateral acceleration change rate evaluation value rather than evaluating only the maximum angle change rate evaluation value. .
In the drift section, a high speed and a large and stable drift angle are required. Based on the average speed evaluation value related to the speed of speed, the average angle evaluation value related to the drift angle magnitude, and the average angle change rate evaluation value related to the drift angle stability, Since it calculates, a high score can be given with respect to the driving | running | working which demonstrated the driving technique requested | required in a drift area.
Also, how much speed can be increased is an important evaluation item. By adding the maximum speed point based on the maximum speed evaluation value to the total of the section scores calculated for each section, the beauty of drift traveling can be accurately evaluated.
Prior to calculating the evaluation value, the maximum speed, average speed, maximum drift angle, average drift angle, maximum drift angle change rate, average drift angle change rate, maximum lateral acceleration change rate, and average lateral acceleration change rate in each section are calculated. By doing so, there is no need to store raw data representing the running situation of the drift racing vehicle, so the amount of data to be stored can be reduced. In addition, the time taken to calculate the evaluation value can be shortened.
In particular, at a venue such as a competition or event, a large number of drift racing vehicles must travel, and it is necessary to score and rank the traveling of each drift racing vehicle. The amount of data transmitted from the traveling state measuring device can be reduced by calculating the traveling data of each section with the traveling state measuring device mounted on the drift racing vehicle. Thereby, even when the communication between the traveling state measuring device and the receiving device is unstable, the data can be easily retransmitted, and the data can be reliably transmitted and received. Further, even when the communication speed is low, the receiving device can receive data from a large number of drift racing vehicles.
Moreover, since the beauty of drift running is evaluated based on the data which recorded the driving | running | working of the drift racing vehicle, it is also possible to score the driving | running | working in a remote place. In this case, the evaluation reference value changes depending on the shape of the course. When the course determination unit determines which course the drift racing vehicle has traveled, it is possible to score based on a reference value corresponding to each course.

(First embodiment)
FIG. 1 shows a drift scoring system 10. The drift scoring system 10 is a system for scoring the drift travel of the drift competition vehicle 12 traveling on the drift competition course 11 in a drift competition or an event venue.
The drift competition vehicle 12 is a passenger car modified for drift competition, for example. The drift racing vehicle 12 is equipped with a traveling state measuring device that measures the traveling state of the drift racing vehicle 12.
The drift competition course 11 includes a start line 111 and a finish line 112, and the section from the start line 111 to the finish line 112 is divided into a plurality of sections 114a to 114f by boundaries 113a to 113e. Each section 114a-114f differs in the required driving technique, and the scoring criteria differ accordingly. Note that the boundaries 113a to 113e are virtual, and it is not necessary for the signs and marks indicating the boundaries 113a to 113e to be provided on the actual drift competition course 11. Or you may install the beacon apparatus which transmits the electromagnetic wave for notifying the drift racing vehicle 12 that it passed the boundary 113a-113e in the boundary 113a-113e vicinity.

The first boundary 113 a is provided in the middle of the straight line portion that continues from the start line 111. A section 114a from the start line 111 to the first boundary 113a is a running section for the drift racing vehicle 12 to accelerate.
The second boundary 113b is provided near the entrance of the first curved portion that curves to the left from the straight section. A section 114b from the boundary 113a to the boundary 113b is a starting section for the drift racing vehicle 12 to start drifting in the first curved portion.

A section 114d from the boundary 113c to the boundary 113d is a drift section through which the drift racing vehicle 12 passes while drifting, similarly to the third section 114c.
The fifth boundary 113e is provided in the vicinity of the entrance of the third curved portion that curves to the right contrary to the second curved portion. A section 114e from the boundary 113d to the boundary 113e is a return section for the drift racing vehicle 12 to reverse the direction of drift.
The finish line 112 is provided near the exit of the third curved portion. A section 114f from the boundary 113e to the finish line 112 is a drift section through which the drift racing vehicle 12 passes while drifting.

The run-up section is not subject to scoring.
In the swing-out section and the swing-back section, it is required to swing back sharply from a high speed.
In the drift section, it is required to stably maintain a large drift angle while minimizing deceleration.
Each section does not necessarily have to be continuous. That is, the previous section and the next section are not separated by one boundary, but the boundary representing the end point of the previous section and the boundary representing the start point of the next section are two different boundaries. There may be, and moreover, the two boundaries may be greatly separated.

  The drift scoring system 10 includes repeaters 131a and 131b, a base station 132, a receiving device 133, a judge terminal device 14, a scoring device 15, a distributor 161, a judge monitor 162, and a facilitator monitor. 163 and a display 164 in the hall. The repeaters 131a and 131b are arranged in the vicinity of the drift competition course 11 and receive and relay radio waves transmitted from a traveling state measuring device having a small transmission output. The base station 132 communicates with the traveling state measuring apparatus directly or via the repeaters 131a and 131b. The receiving device 133 receives the running data representing the running status of the drift racing vehicle 12 measured by the running status measuring device from the running status measuring device via the base station 132. The judge terminal device 14 is, for example, a notebook personal computer or the like, and inputs a scoring result by the judge 18 by executing an installed application program or dedicated software. The judges 18 score human factors that cannot be scored by the machine. The scoring device 15 is, for example, a notebook personal computer or the like, and by running the installed application program or dedicated software, the running data received by the receiving device 133 or by the judge 18 input to the judge terminal device 14.

The judge monitor 162, the facilitator monitor 163, and the on-site display 164 receive the image signal distributed by the distributor 161 and display the scoring result by the scoring device 15.

FIG. 2 shows the traveling state measuring device 20. The traveling state measurement device 20 includes a power supply unit 21, a measurement unit 22, and a transmission unit 23. The power supply unit 21 includes a storage battery, for example, and supplies power to the measurement unit 22 and the transmission unit 23. The measurement unit 22 measures the traveling state of the traveling state measuring device 20 and generates traveling data. The transmission unit 23 wirelessly transmits the travel data generated by the measurement unit 22.
The measurement unit 22 is, for example, a DriftBox manufactured by RaceLogic (UK), and measures the speed, drift angle, and the like of the drift racing vehicle 12. The measurement unit 22 includes, for example, a position measurement unit 221, an orientation measurement unit 222, a boundary storage unit 223, a section determination unit 224, and a data calculation unit 225.
The position measuring unit 221 repeatedly measures the position of the drift racing vehicle 12 at a predetermined cycle (for example, 0.1 second). For example, the position measurement unit 221 calculates the position where the GPS antenna is disposed by receiving radio waves from a GPS satellite with a receiver of the global positioning system (GPS).
The direction measuring unit 222 repeatedly measures the direction of the drift racing vehicle 12 at a predetermined cycle (for example, 0.1 second). For example, the direction measuring unit 222 measures the horizontal angular velocity of the drift racing vehicle 12 with a yaw rate sensor, and calculates the orientation of the drift racing vehicle 12 by integrating the measured angular velocity. Alternatively, the direction measuring unit 222 calculates the direction of the drift racing vehicle 12 by measuring the direction of geomagnetism with a geomagnetic sensor. Alternatively, the direction measuring unit 222 receives radio waves from GPS satellites with two GPS receivers, calculates the positions of the two GPS antennas, and calculates the direction of the drift racing vehicle 12 from the difference between the two calculated positions. To do. In this case, one of the two GPS receivers is shared with the position measurement unit 221.
The boundary storage unit 223 stores the positions of the start line 111, the boundaries 113a to 113e, and the finish line 112. For example, the boundary storage unit 223 includes a slot for inserting a memory card, and the organizer of the competition distributes the memory card storing the position of the start line 111 and the like to each athlete, and the distributed memory card is distributed to each competition. The boundary storage unit 223 stores the position of the start line 111 and the like when the person inserts it into the traveling state measurement device 20 mounted on his / her drift racing vehicle 12.
The section determination unit 224 determines which section of the sections 114 a to 114 f the traveling state measurement device 20 is based on the position of the drift racing vehicle 12 measured by the position measurement unit 221.
The data calculation unit 225 is based on the position of the drift racing vehicle 12 measured by the position measurement unit 221 and the orientation of the drift racing vehicle 12 measured by the orientation measurement unit 222 by executing, for example, firmware installed in the DriftBox. Then, the speed of the drift racing vehicle 12 is calculated, and based on the section determined by the section determination unit 224, the calculated values such as the speed are aggregated for each section, and the average value, maximum value, minimum value, etc. are calculated. .

  In addition, the structure which supplies the power supply of the drift racing vehicle 12 directly to the measurement part 22 or the transmission part 23 without providing the power supply part 21 may be sufficient. However, when the measurement unit 22 includes a GPS receiver, it may take time to start up when the power is turned on. If the power source is cut off due to the engine stall of the drift racing vehicle 12 or the like, the running situation of the drift racing vehicle 12 may not be measured. Moreover, there is a possibility that the power supply from the drift racing vehicle 12 may be interrupted due to poor contact. For this reason, it is preferable to provide the power supply unit 21.

In FIG. 3, the position of the drift racing vehicle 12 measured by the position measuring unit 221 is indicated by a cross. The position of the drift racing vehicle 12 is represented by a set of latitude and longitude, for example.
The data calculation unit 225 moves the drift racing vehicle 12 in the north-south direction and the east-west direction between two times based on the position of the drift racing vehicle 12 at a certain time and the position of the drift racing vehicle 12 at the next time. By calculating the distance and calculating the quotient obtained by dividing the calculated moving distance by the difference between the two times, the moving speed of the drift racing vehicle 12 in the north-south direction and the east-west direction is obtained. The data calculation unit 225 calculates the absolute value of the speed of the drift racing vehicle 12 and the moving direction based on the calculated moving speeds in the north-south direction and the east-west direction.
If the drift racing vehicle 12 is not drifting, the moving direction of the drift racing vehicle 12 matches the direction of the drift racing vehicle 12. On the other hand, when the drift racing vehicle 12 is drifting, the moving direction of the drift racing vehicle 12 and the direction of the drift racing vehicle 12 are different. The data calculation unit 225 obtains the drift angle of the drift racing vehicle 12 by calculating the difference between the calculated moving direction and the direction of the drift racing vehicle 12 measured by the direction measurement unit 222.
Based on the drift angle calculated for a certain time and the drift angle calculated for the next time, the data calculation unit 225 calculates and calculates the amount of change in the drift angle of the drift racing vehicle 12 between the two times. The drift angle change rate is obtained by calculating a quotient obtained by dividing the change amount of the drift angle by the difference between the two times. The drift angle change rate represents the amount of change in drift angle per unit time.
The data calculating unit 225 also determines the drift racing vehicle 12 between two times based on the moving speed of the drift racing vehicle 12 calculated for a certain time and the moving speed of the drift racing vehicle 12 calculated for the next time. By calculating the amount of change in the moving speed in the north-south direction and east-west direction, and by calculating the quotient obtained by dividing the amount of change in the calculated moving speed by the difference between the two times, Find the acceleration. The data calculation unit 225 performs coordinate conversion of the calculated acceleration on the basis of the traveling direction of the drift racing vehicle 12 to obtain the vertical acceleration and the lateral acceleration of the drift racing vehicle 12. The longitudinal acceleration is an acceleration in the traveling direction of the drift racing vehicle 12, and the lateral acceleration is an acceleration in a direction perpendicular to the traveling direction of the drift racing vehicle 12 in the horizontal plane.
Furthermore, the data calculation unit 225 calculates the amount of change in the lateral acceleration of the drift racing vehicle 12 between the two times based on the lateral acceleration calculated for a certain time and the lateral acceleration calculated for the next time. By calculating the quotient obtained by dividing the calculated change amount of the lateral acceleration by the difference between the two times, the lateral acceleration change rate of the drift racing vehicle 12 is obtained. The lateral acceleration change rate represents the amount of change in lateral acceleration per unit time.
Further, the data calculation unit 225 calculates the amount of change in the vertical acceleration of the drift racing vehicle 12 between the two times based on the vertical acceleration calculated for a certain time and the vertical acceleration calculated for the next time, By calculating a quotient obtained by dividing the calculated change amount of the vertical acceleration by the difference between the two times, the vertical acceleration change rate of the drift racing vehicle 12 is obtained. The vertical acceleration change rate represents the amount of change in vertical acceleration per unit time.

The section determination unit 224 compares the position of the drift racing vehicle 12 at each time with the positions of the start line 111, the boundaries 113a to 113e and the finish line 112 stored in the boundary storage unit 223, and determines which of the drift racing vehicle 12 Determine if you are in a section.
The data calculation unit 225 aggregates the speed, drift angle, drift angle change rate, lateral acceleration change rate, and vertical acceleration change rate calculated for each time for each section based on the determination result by the section determination unit 224. The maximum value, average value, and minimum value are calculated. Moreover, the data calculation part 225 calculates | requires the area time of the drift racing vehicle 12 by calculating the time required for the drift racing vehicle 12 to enter from a certain section until it leaves the section. The data calculation unit 225 generates traveling data representing the speed, drift angle, drift angle change rate, lateral acceleration change rate, and vertical acceleration change rate maximum value, average value, and minimum value calculated for each section, and the section time. . Note that the travel data need not include all these values, and may include only some of these values.

  The travel data thus generated is wirelessly transmitted by the transmission unit 23 and received by the reception device 133 via the repeaters 131a and 131b and the base station 132. By summing up each section on the side of the traveling state measuring device 20, the amount of data transmitted by the traveling state measuring device 20 can be suppressed. In particular, since there are a large number of athletes at the venue of the competition, a large amount of running data is transmitted. In addition, the radio station installed temporarily has a small output and is affected by noise emitted from the drift racing vehicle 12 or the like, so the communication speed cannot be increased very much. In addition, a single transmission is not always successful, and the same data may have to be retransmitted many times. Since the success rate of communication is increased by suppressing the amount of data transmitted by the traveling state measuring device 20, the reliability of communication is increased and stable communication can be ensured. In addition, since the time required for communication can be shortened, the time required for obtaining the scoring result can be shortened.

In addition, the structure provided with the acceleration measurement part which measures the acceleration of the drift racing vehicle 12 may be sufficient as the measurement part 22 instead of the position measurement part 221. In that case, the data calculation unit 225 calculates the speed of the drift racing vehicle 12 by integrating the acceleration measured by the acceleration measurement unit, and calculates the position of the drift racing vehicle 12 by further integrating the calculated speed. To do.
Moreover, even if it is the structure which the area determination part 224 determines the area where the drift racing vehicle 12 exists by receiving the electromagnetic wave etc. from the beacon apparatus installed in the drift competition course 11 without providing the boundary memory | storage part 223. Good.
The running condition measuring device 20 is not limited to the configuration described above, and measures the running situation of the drift racing vehicle 12 such as the position, speed, acceleration, drift angle of the drift racing vehicle 12 and the rate of change thereof, and the average for each section. Any value may be used as long as the value, maximum value, minimum value, etc. are calculated and transmitted.

FIG. 4 shows the scoring device 15. The scoring device 15 scores the travel of the drift racing vehicle 12 based on the travel data received by the receiving device 133. The scoring device 15 includes an evaluation item storage unit 511, a reference value storage unit 512, a weight storage unit 513, a data acquisition unit 531, a judge scoring acquisition unit 532, an evaluation value calculation unit 541, and a comprehensive evaluation value calculation. Unit 542, score calculation unit 543, and scoring result output unit 55.
The evaluation item storage unit 511 stores, in advance, an evaluation item for which the evaluation value calculation unit 541 should calculate an evaluation value and an index used by the evaluation value calculation unit 541 for calculating the evaluation value for each evaluation item for each type of section. I remember it.
The reference value storage unit 512 stores in advance, for each section, a reference value used by the evaluation value calculation unit 541 for calculating the evaluation value.
The weight storage unit 513 stores in advance, for each section, the weight used by the score calculation unit 543 to calculate the score.
The data acquisition unit 531 acquires travel data received by the receiving device 133.
The judges scoring acquisition unit 532 acquires the scoring results by the judges 18 input to the judges terminal device 14.

The evaluation value calculation unit 541 calculates evaluation values related to a plurality of evaluation items for each section based on the travel data acquired by the data acquisition unit 531. For example, the evaluation value calculation unit 541 determines an evaluation item for which an evaluation value should be calculated for the section according to the evaluation item stored in the evaluation item storage unit 511. The evaluation value calculation unit 541 acquires the value of the evaluation item for which the evaluation value is to be calculated from the travel data acquired by the data acquisition unit 531. The evaluation value calculation unit 541 acquires the reference value of the evaluation item from the reference value stored in the reference value storage unit 512. The evaluation value calculation unit 541 obtains a ratio of the value to the reference value by dividing the value of the evaluation item by the reference value. The evaluation value calculation unit 541 acquires an index used for the evaluation item from the index stored in the evaluation item storage unit 511. The evaluation value calculation unit 541 obtains an evaluation value for the evaluation item by raising the ratio calculated for the evaluation item to a power of a predetermined index.
The comprehensive evaluation value calculation unit 542 calculates the comprehensive evaluation value of the drift racing vehicle 12 based on the evaluation value calculated by the evaluation value calculation unit 541 for each section. For example, the comprehensive evaluation value calculation unit 542 calculates a product of a plurality of evaluation values calculated by the evaluation value calculation unit 541 for the section, and sets the product as a comprehensive evaluation value for the section.
The score calculation unit 543 calculates the score of the drift racing vehicle 12 based on the comprehensive evaluation value calculated for each section by the comprehensive evaluation value calculation unit 542 and the scoring by the judge 18 acquired by the judge scoring acquisition unit 532. To do. For example, the score calculation unit 543 acquires the weight stored by the weight storage unit 513 for each section. The score calculation unit 543 calculates the product of the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 542 and the acquired weight for each section, and sets it as the section score. The score calculation unit 543 calculates the score by machine scoring by summing up the section scores calculated for all the sections. The score calculation unit 543 obtains the score of the drift racing vehicle 12 by adding the score obtained by scoring by the judge 18 to the score obtained by the mechanical scoring.
The scoring result output unit 55 outputs the score calculated by the score calculating unit 543, the comprehensive evaluation value of each section calculated by the comprehensive evaluation value calculating unit 542, and the like as the scoring result.

  The evaluation items for which the evaluation value calculation unit 541 calculates the evaluation value include, for example, the maximum speed that is the maximum speed of the drift racing vehicle 12 in the section, and the average value of the speed of the drift racing vehicle 12 in the section. The average speed, the maximum angle that is the maximum drift angle of the drift racing vehicle 12 in the section, the average angle that is the average drift angle of the drift racing vehicle 12 in the section, and the drift of the drift racing vehicle 12 in the section The maximum angle change rate that is the maximum value of the angle change rate, the average angle change rate that is the average value of the drift angle change rate of the drift racing vehicle 12 in the section, and the maximum value of the lateral acceleration change rate of the drift racing vehicle 12 in the section The maximum lateral acceleration change rate, and the average value of the lateral acceleration change rate of the drift racing vehicle 12 in that section The lateral acceleration change rate, the maximum vertical acceleration change rate that is the maximum value of the vertical acceleration change rate of the drift racing vehicle 12 in that section, and the average vertical acceleration change rate that is the average value of the vertical acceleration change rate of the drift racing vehicle 12 in that section There is a section time that is the time taken for the drift racing vehicle 12 to pass through the section.

As described above, the required driving technique varies depending on the type of section. For this reason, the evaluation value to be calculated by the evaluation value calculation unit 541 changes.
For example, in the swinging out section and the returning section, it is required to swing back sharply from a high speed. Therefore, in order to obtain a high score, it is necessary that the average speed is large, the maximum angle change rate is large, and the average lateral acceleration change rate is large. Therefore, for example, the evaluation item storage unit 511 stores an average speed, a maximum angle change rate, and an average lateral acceleration change rate as evaluation items for which the evaluation value calculation unit 541 should calculate evaluation values for the swing-out section and the return section. “1” is stored as the index used for the average speed, “1” is stored as the index used for the maximum angle change rate, and “1” is stored as the index used for the average lateral acceleration change rate. The index means that the higher the absolute value, the more important the evaluation item is. In this example, the same index is used to emphasize the three evaluation items to the same extent. Further, the index being “1” means that the ratio of the original value to the reference value is used as the evaluation value as it is. Accordingly, the evaluation value calculation unit 541 calculates a quotient obtained by dividing the average speed by the reference value for the swing section and the return section, and sets the average speed evaluation value, and the maximum angle change rate by the reference value. The divided quotient is calculated to obtain the maximum angle change rate evaluation value, and the quotient obtained by dividing the average lateral acceleration change rate by the reference value is calculated to obtain the average lateral acceleration change rate evaluation value. The comprehensive evaluation value calculation unit 542 calculates the product of the average speed evaluation value, the maximum angle change rate evaluation value, and the average lateral acceleration change rate evaluation value, and sets it as the overall evaluation value of the drift racing vehicle 12 in that section. .

  Through experiments, the inventor has realized that in evaluating the sharpness of turning, the impression received by the viewer cannot be accurately reflected only by the maximum angle change rate. By adding the average lateral acceleration change rate to the evaluation items, it was possible to score accurately reflecting the impression received by the viewer.

  In the drift section, it is required to stably maintain a large drift angle while keeping the speed high. Therefore, in order to obtain a high score, it is necessary that the average speed is large, the average angle is large, and the average angle change rate is small. Therefore, for example, the evaluation item storage unit 511 stores the average speed, the average angle, and the average angle change rate as evaluation items for the evaluation value to be calculated by the evaluation value calculation unit 541 for the drift section, and as an index used for the average speed. “1”, “1” as an index used for the average angle, and “−1” as an index used for the average angle change rate are stored. The negative index means that the smaller the original value is, the larger the evaluation value is and high evaluation can be obtained. Accordingly, for the drift section, the evaluation value calculation unit 541 calculates a quotient obtained by dividing the average speed by the reference value to obtain an average speed evaluation value, and calculates a quotient obtained by dividing the average angle by the reference value. The average angle evaluation value is calculated, and the reciprocal of the quotient obtained by dividing the average angle change rate by the reference value is calculated to obtain the average angle change rate evaluation value. The comprehensive evaluation value calculation unit 542 calculates the product of the average speed evaluation value, the average angle evaluation value, and the average angle change rate evaluation value, and sets it as the comprehensive evaluation value of the drift racing vehicle 12 in that section.

As described above, the evaluation item for which the evaluation value calculation unit 541 should calculate the evaluation value and the index used for each evaluation item vary depending on the type of the section. For this reason, the evaluation item storage unit 511 stores an evaluation item and an index used for each evaluation item for each type of section. The evaluation items and indices described above are examples, and the evaluation item storage unit 511 may be configured to store evaluation items and indices different from the evaluation items mentioned in the above examples. The exponent is not limited to a natural number, and may be a negative number as in the above-described example, or may be a decimal or a fraction. For example, if the index is “0.5”, it means that the square root of the quotient obtained by dividing the value of the evaluation item by the reference value is used as the evaluation value of the evaluation item, and the index is “−2/3”. If there is, it means that the reciprocal of the square root of the quotient obtained by dividing the value of the evaluation item by the reference value is used as the evaluation value of the evaluation item.
Further, the reference value used by the evaluation value calculation unit 541 for each evaluation item is different for each section even if the type of the section is the same. For this reason, the reference value storage unit 512 stores a reference value used for each evaluation item for each section. The reference value stored in the reference value storage unit 512 may be calculated based on traveling data obtained by actually traveling the drift racing course 11 on the drift competition course 11, or theoretically calculated. It may be. Alternatively, the reference value may be a constant value regardless of the section.

In addition, there are a relatively simple section and a section that requires advanced technology depending on the section. Therefore, in summing up the scores in each section, the weight of simple sections is reduced, and the weight of sections that require advanced technology is increased. To. Therefore, for example, the weight storage unit 513 sets “35” as the weight of the section 114b, “30” as the weight of the section 114c, “20” as the weight of the section 114d, “10” as the weight of the section 114e, and weights the section 114f. Is stored as “5”. In addition, about the area which is not the object of scoring like the area 114a, the structure which the weight memory | storage part 513 memorize | stores "0" as a weight may be sufficient. Accordingly, the score calculation unit 543 multiplies the total evaluation value of the section 114b by 35 times, and multiplies the total evaluation value of the section 114c by 30 times based on the total evaluation value calculated by the comprehensive evaluation value calculation unit 542 for each section. The total evaluation value of the section 114d is multiplied by 20, the total evaluation value of the section 114e is multiplied by 10, and the total evaluation value of the section 114f is multiplied by five to obtain the section score of each section, and the calculated section scores are totaled.
Note that the weighting of each section may be the same. In other words, the total evaluation score of each section may be summed without weighting.
Further, the score calculation unit 543 may be configured to convert the comprehensive evaluation value into the section score by a predetermined monotonically increasing function, instead of simply multiplying by weight. For example, the score calculation unit 543 divides a predetermined constant by the comprehensive evaluation value, subtracts the calculated quotient from another constant, and sets the calculated difference as a segment score. This makes it possible to score more like a human sense.

Moreover, there may be an item evaluated independently from the score of each section. For example, since the section 114b that is the starting section is a section before the first curve, there is a possibility that the first curve cannot be completely turned if the speed is increased too much, and there is courage to step on the accelerator. Therefore, the maximum speed in the starting section may be evaluated independently of the score in that section. For example, the evaluation value calculation unit 541 calculates the maximum speed evaluation value for the maximum speed for the starting section. However, the maximum speed evaluation value is not used for the overall evaluation value calculation unit 542 to multiply with other evaluation values, but is used to calculate a score independent of the overall evaluation value of the section. For example, the score calculation unit 543 calculates the maximum speed point by subtracting the reciprocal of the maximum speed evaluation value from “1” and multiplying the calculated difference by a predetermined coefficient. Note that the maximum speed point is not limited to the starting section, and may be calculated for other sections, or may be calculated in common for all sections.
The score calculation unit 543 calculates a score by machine scoring by adding a score calculated independently from the section score in each section, such as the maximum speed point, to the sum of the section scores in each section. Further, the score calculation unit 543 calculates the score of the drift racing vehicle 12 by adding the score obtained by scoring the judge 18.

  Moreover, when the predetermined condition is not satisfied in each section, the score in the section may be set to a predetermined value (for example, “0”). For example, when the minimum speed in a certain section is a predetermined minimum speed (for example, 20 km / h) or less, the score in that section is set to “0”. Alternatively, when the maximum angle change rate in a certain section exceeds a predetermined threshold, the score in that section is set to “0”, assuming that the drift racing vehicle 12 has spun. Alternatively, when the average angle in the drift section is equal to or less than a predetermined threshold, the score in that section is set to “0”, assuming that the drift racing vehicle 12 is not drifting. For example, the comprehensive evaluation value calculation unit 542 determines whether or not the condition is satisfied. If the condition is not satisfied, the comprehensive evaluation value in the section is not a product of the evaluation values but a predetermined value (for example, “0 ]).

As described above, the evaluation value is calculated for each evaluation item, the product of the evaluation values is calculated, and the total evaluation value of the drift racing vehicle 12 is obtained. Can be given a high evaluation.
By weighting and summing the overall evaluation values for each section, it is possible to calculate a score in consideration of the difficulty of the section.
Since the scoring is based on information that can be measured objectively, such as the position and orientation of the drift racing vehicle 12, it is not affected by the subjectivity of the scorer. In the sensitivity evaluation based on the subjectivity of the scorer, it is difficult to keep the evaluation standard constant, and the reproducibility of the evaluation is poor. Even if the evaluation criteria can be kept constant, a competitor who receives a low evaluation is dissatisfied, and in some cases, can develop into grudge against the individual scorer.
Since it does not depend on the subjectivity of the grader, the evaluation criteria can be kept constant and the reproducibility of the evaluation can be ensured. It is possible to prevent the competitors and spectators from having dissatisfaction and distrust with the scoring results.

As a reference value used for calculation of the evaluation value, by using a value calculated based on traveling data obtained by actually running the drift competition vehicle 12 on the drift competition course 12, a standard in the drift competition course 11 is used. You can score on the basis of running. For example, if the reference value is calculated by averaging the running data of a plurality of drift racing vehicles 12 that have achieved high scores in the previous competition held using the same drift competition course 11, there are few mistakes. A reference value based on high-level driving data can be obtained. Alternatively, the reference value may be calculated by collecting running data during a trial run of the current competition, and picking up and averaging the running data for running with no mistakes.
Further, if a theoretically calculated value is used as the reference value, an absolute evaluation can be performed instead of a relative evaluation based on past driving.
Or it is good also as a structure which uses a fixed value as a reference value irrespective of an area or a drift competition course.

  In addition, the judges can score points that cannot be evaluated by running data alone, and the scores calculated based on the running data and scores from the judges can be summed up for more accurate scoring. . The items that the judges score are, for example, the human impression, such as overall impression and completeness such as timidity, force, smoke, etc., the ability to pull out the vehicle ability, the courage, the spirit of challenge, uniqueness, and novelty. There are items that can only be evaluated. In addition, position measurement by GPS can be performed with high accuracy with respect to relative movement within a relatively short time. However, in order to increase absolute position measurement accuracy, it is very expensive. Equipment is required. For this reason, when GPS is used to measure the position in the traveling state measuring device 20, the measured values such as speed and moving direction are accurate and can be used to calculate the score, but the absolute position measured value is not necessarily It is not always accurate and cannot be used to calculate scores. For example, running at the edge of the wall of the drift competition course 11 deserves a high evaluation, but if a running line is determined and scored based on the position of the drift racing vehicle 12 measured by the running situation measuring device 20, a measurement error may result. There is a possibility that the scoring may not be performed correctly, and a more accurate evaluation is possible if the judges score. In addition, points deducted by the steering wheel operation and brake operation methods may be used as scoring items by the judges.

  Further, if only scoring by machine scoring is calculated without adding scoring by the judges, it is not necessary for the judges to see the drift racing vehicle 12 running. For this reason, for example, scoring can also be given for practice running. By scoring the practice run and providing the athlete with the scoring results, the technical level of the athlete can be improved.

In addition to the single-run type in which each drift racing vehicle 12 travels alone as a competition format, there are a follow-up format in which two drift racing vehicles 12 travel simultaneously. In the follow-up type, the vehicle is divided into a preceding vehicle and a follower vehicle and starts simultaneously. The preceding vehicle is required to travel in its own best, and the follower vehicle is required to drift in accordance with the preceding vehicle. In the case of such a competition format, for example, if ranking is performed by scoring the traveling of the preceding vehicle using mechanical scoring, the rank of the follow-up vehicle can be determined based on this.
Alternatively, a configuration may be used in which a scoring is also performed for a follower vehicle by using a machine scoring system, and a judge scores a distance from a preceding vehicle.

In addition, the evaluation criteria of what kind of driving is beautiful may differ depending on the host country of the competition and the difference in aesthetics. For example, in the drift section, there is a way of thinking that the magnitude of the drift angle is most important and the stability of speed and drift angle is not so important.
In the drift scoring system 10, since the evaluation criteria are determined by the evaluation items stored in the evaluation item storage unit 511 and the index for each evaluation item, different evaluations can be made by changing these values stored in the evaluation item storage unit 511. It can also meet standards.

The evaluation value calculation unit 541A acquires the reference value of each section in the drift competition course determined by the course determination unit 521 from the reference value storage unit 512A, and evaluates each section based on the value calculated by the data calculation unit 525. An evaluation value related to the evaluation item stored in the item storage unit 511 is calculated.
The comprehensive evaluation value calculation unit 542 calculates, for each section, the comprehensive evaluation value of the drift racing vehicle in the section based on the evaluation value calculated by the evaluation value calculation unit 541A.
The score calculation unit 543A obtains the weight of each section in the drift competition course determined by the course determination unit 521 from the weight storage unit 513A, and weights the total evaluation value calculated by the comprehensive evaluation value calculation unit 542 for each section. The score is calculated, and the calculated section score is added to calculate the score of the drift racing vehicle.

There is no need to know the position of the boundary in advance. Further, since the drift competition course is determined based on the position of the drift competition vehicle represented by the running data, the user does not need to separately notify the scoring device 15A which drift course has been run. That is, the user can use the scoring service simply by transmitting the travel data without any prior preparation.
