[0005] [Patent Document 1] International Publication No. 2018 / 190152 [Patent Document 2] U.S. Patent No. 10,157,321 [Patent Document 3] U.S. Patent No. 10,817,950 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]
[0006] Lean vehicles are highly mobile and convenient, and are therefore used in a variety of situations. Therefore, a lean vehicle driving data processing device that generates and outputs output data specific to a lean vehicle is required to generate and output the output data specific to a lean vehicle, taking into account a variety of driving situations. In particular, when the lean vehicle driving data processing device generates economic loss-related data as the output data, it is required to generate more accurate economic loss-related data based on the driving data of the lean vehicle.
[0007] Furthermore, in order to generate more accurate economic loss-related data in the lean vehicle driving data processing device, if data on various conditions such as driving conditions is to be obtained, the types and amounts of data to be processed by the lean vehicle driving data processing device will be extremely large. This increases the hardware load in the lean vehicle driving data processing device. This increases the hardware resources required by the lean vehicle driving data processing device, resulting in restrictions on the design of the hardware resources. This reduces the degree of freedom in designing the hardware resources of the lean vehicle driving data processing device.
[0008] The present invention aims to provide a lean vehicle driving data processing device that can improve the accuracy of economic loss-related data obtained based on lean vehicle driving data while increasing the design freedom of hardware resources. [Means for solving the problem]
[0009] The inventors have gained the following new knowledge while studying output data specific to lean vehicles based on the running data of lean vehicles, which is generated and output by a lean vehicle running data processing device.
[0010] Unlike a four-wheel vehicle, a lean vehicle leans to the right when turning right and leans to the left when turning left. Therefore, when turning a lean vehicle left or right, the driver must perform an action of leaning the lean vehicle to turn the lean vehicle and an action of raising the lean vehicle after the lean vehicle has finished turning. Also, unlike a four-wheel vehicle, a lean vehicle changes course by tilting the vehicle body in the left-right direction. Moreover, since the dimensions of a lean vehicle in the left-right direction are smaller than those of a four-wheel vehicle, the degree of freedom of the running position in the left-right direction is high. Therefore, in the case of a lean vehicle, course changes occur frequently.
[0011] In such lean vehicles, the driver's driving skill and driving tendency are easily reflected in sudden movements of the vehicle body leaning to the left or right when changing lanes, for example.
[0012] The inventors also found that there is a high correlation between the sudden left-right tilt of the vehicle body, which reflects the driver's driving skill and driving tendency as described above, and data related to economic loss. Therefore, the inventors realized that it is easy to obtain a correlation between the driver operating the lean vehicle and economic loss from each data related to the sudden left-right tilt of the vehicle body, which reflects the driver's driving skill and driving tendency as described above.
[0013] The lane change means an operation of a lean vehicle in which the vehicle changes course while traveling in the same direction, and includes an operation of the lean vehicle changing lanes.
[0014] Taking the above into consideration, the inventors have realized that by processing lean vehicle driving data including data related to sudden left and right tilting movements of the vehicle body, which reflect the driving skills and driving tendencies of the driver of the lean vehicle, it is possible to more accurately generate and output output data specific to lean vehicles that can be used for services related to economic losses, such as insurance and finance.
[0015] In addition, the inventors have realized that by using the above-mentioned lean vehicle driving data for processing, the type of data to be processed can be limited compared to processing lean vehicle driving data in all driving scenes. This makes it possible to suppress an increase in the amount of data to be processed by the lean vehicle driving data processing device, thereby reducing the load on the hardware of the lean vehicle driving data processing device. Therefore, it is possible to increase the design freedom of the hardware resources of the lean vehicle driving data processing device.
[0016] As described above, the inventors have discovered that by using lean vehicle driving data including data related to sudden left and right tilting movements of the vehicle body, which reflect the driving skills and driving tendencies of the driver of the lean vehicle, for processing, it is possible to improve the accuracy of economic loss-related data obtained based on the lean vehicle driving data while increasing the design freedom of hardware resources, and have come up with the following configuration.
[0017] A lean vehicle driving data processing device according to one embodiment of the present invention is a lean vehicle driving data processing device having a memory that stores lean vehicle driving data, which is driving data of a lean vehicle that leans to the left when turning left and leans to the right when turning right, and a processor that generates economic loss-related data based on the lean vehicle driving data stored in the memory using an economic loss-related data generation model that generates economic loss-related data used for services related to economic loss in accordance with data indicating sudden movement of the vehicle body contained in the lean vehicle driving data, and outputs the generated economic loss-related data. The economic loss related data generation model is configured to define the lean vehicle driving data in which a driver drives a first route in a first lean vehicle during a first time period on a first date such that neither the vehicle body accelerates or decelerates in the fore-and-aft direction nor the vehicle body tilts in the left-and-right direction is sudden as first lean vehicle driving data, and define the lean vehicle driving data in which the driver drives the first route in the first lean vehicle during the first time period on the first date such that the vehicle body does not accelerate or decelerate in the fore-and-aft direction and the vehicle body tilts in the left-and-right direction is sudden as second lean vehicle driving data, so that first economic loss related data generated based on the first lean vehicle driving data and second economic loss related data generated based on the second lean vehicle driving data are different data from each other.
[0018] As a result, the economic loss-related data generation model can obtain economic loss-related data in response to sudden left-right tilting movements of the vehicle body, based on data indicating the left-right tilting movements of the vehicle body contained in the lean vehicle driving data, which reflects the driving skills and driving tendencies of the driver of the lean vehicle.
[0019] The economic loss related data generation model is configured such that the second economic loss related data obtained based on the second lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body tilts sharply in the left-right direction is different from the first economic loss related data obtained based on the first lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body does not tilt sharply in the left-right direction. Therefore, the economic loss related data generation model is configured such that the second economic loss related data obtained based on the second lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body does not tilt sharply in the left-right direction is different from the first economic loss related data obtained based on the first lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body does not tilt sharply in the left-right direction. left and right Economic loss related data can be generated according to the sudden movement in the direction of inclination.
[0020] In a lean vehicle, the driver's driving skill and driving tendency are likely to be reflected in the sudden left-right tilt of the vehicle body. Therefore, by using the economic loss related data generation model as described above to generate economic loss related data according to the sudden left-right tilt of the vehicle body, it is possible to accurately obtain economic loss related data according to the driver's driving skill and driving tendency. Moreover, the predicted driving level of the driver of a lean vehicle differs depending on the driving skill of the driver. Therefore, the predicted driving level of the driver is also likely to be reflected in the sudden left-right tilt of the vehicle body. Therefore, by generating economic loss related data according to the sudden left-right tilt of the vehicle body as described above, it is possible to accurately obtain economic loss related data according to the predicted driving level of the driver.
[0021] In addition, by using data indicating the left-right tilting movement of the vehicle body included in the lean vehicle driving data, which reflects the driving skills and driving tendencies of the driver of the lean vehicle, it is possible to suppress an increase in the amount of data to be processed compared to the case where all lean vehicle driving data is used. Therefore, it is possible to reduce the load on the hardware in the lean vehicle driving data processing device. Therefore, it is possible to increase the design freedom of the hardware resources of the lean vehicle driving data processing device.
[0022] As a result, it is possible to provide a lean vehicle driving data processing device that can improve the accuracy of economic loss-related data obtained based on lean vehicle driving data while increasing the design freedom of hardware resources.
[0023] According to another aspect, the lean vehicle driving data processing device of the present invention preferably includes the following configuration: When the driving of the lean vehicle during a period from when the attitude and longitudinal speed of the lean vehicle change from a predetermined state to when they return to the predetermined state is defined as one driving cycle, the first lean vehicle driving data and the second lean vehicle driving data each include data for one driving cycle or more, and the economic loss related data generation model is configured to generate economic loss related data corresponding to a sudden left-right tilting movement of the vehicle body based on data indicating a left-right tilting movement of the vehicle body for one driving cycle or more included in the lean vehicle driving data so that the first economic loss related data generated based on the first lean vehicle driving data and the second economic loss related data generated based on the second lean vehicle driving data are different data from each other.
[0024] As a result, the lean vehicle driving data includes data for one or more driving cycles, and therefore, using the economic loss related data generation model, economic loss related data corresponding to a sudden left / right tilt of the vehicle body can be generated based on data indicating a left / right tilt of the vehicle body for one or more driving cycles included in the lean vehicle driving data that reflects the driving skill and driving tendency of the driver of the lean vehicle.
[0025] Moreover, the second lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body tilts sharply in the left-right direction includes data for one or more driving cycles, and the first lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body does not tilt sharply in the left-right direction includes data for one or more driving cycles. Therefore, economic loss-related data corresponding to a sudden tilt of the vehicle body in the left-right direction can be generated with higher accuracy by using the economic loss-related data generation model configured so that the second economic loss-related data obtained based on the second lean vehicle driving data is different from the first economic loss-related data obtained based on the first lean vehicle driving data.
[0026] Furthermore, by the processor generating economic loss related data based on data from the lean vehicle driving data that indicates the left-right tilting of the vehicle body, the increase in the amount of data to be processed can be suppressed more than when all data in the lean vehicle driving data is used. Therefore, the load on the hardware in the lean vehicle driving data processing device can be further reduced. Therefore, the degree of freedom in designing the hardware resources of the lean vehicle driving data processing device can be further increased.
[0027] As a result of the above, it is possible to provide a lean vehicle driving data processing device that can improve the accuracy of economic loss-related data obtained based on lean vehicle driving data while increasing the design freedom of hardware resources.
[0028] According to another aspect, the lean vehicle running data processing device of the present invention preferably includes the following configuration: The first lean vehicle running data and the second lean vehicle running data include at least data related to roll motion.
[0029] In this way, since the first lean vehicle driving data and the second lean vehicle driving data include at least data related to roll motion, the first lean vehicle driving data and the second lean vehicle driving data include data indicating a lateral tilting movement of the vehicle body. Therefore, using an economic loss related data generation model, economic loss related data corresponding to a sudden lateral tilting movement of the vehicle body can be generated based on the data indicating the lateral tilting movement of the vehicle body included in the lean vehicle driving data that reflects the driver's driving skill and driving tendency.
[0030] According to another aspect, the lean vehicle driving data processing device of the present invention preferably includes the following configuration: The sudden left-right tilting movement of the vehicle body is a movement in which data indicating the left-right tilting movement of the vehicle body included in the lean vehicle driving data is greater than a threshold value.
[0031] This allows the processor to easily determine data indicating abrupt left-right tilting of the vehicle body from among data indicating left-right tilting of the vehicle body included in the lean vehicle driving data. Therefore, using the economic loss related data generation model, economic loss related data corresponding to the abrupt left-right tilting of the vehicle body can be easily generated based on the data indicating the abrupt left-right tilting of the vehicle body.
[0032] According to another aspect, the lean vehicle driving data processing device of the present invention preferably includes the following configuration: the sudden movement of the vehicle body tilting in the left / right direction includes at least one of a sudden leaning motion for turning, a sudden raising motion, and a sudden change of course in the lean vehicle.
[0033] The sudden leaning and raising operations for turning a lean vehicle and the sudden course change of the lean vehicle tend to reflect the difference in driving skill and driving tendency of the driver who drives the lean vehicle. Also, as described above, there is a high correlation between the sudden leaning, raising, and course change, which reflect the driving skill and driving tendency of the driver, and data related to economic loss. Therefore, it is easy to obtain a correlation between the driver who drives the lean vehicle and economic loss from the data related to the sudden leaning, raising, and course change.
[0034] Therefore, the economic loss related data can be obtained with high accuracy based on the data related to the sudden leaning operation, the sudden lifting operation, and the sudden course change among the lean vehicle driving data.
[0035] According to another aspect, the lean vehicle driving data processing device of the present invention preferably includes the following configuration. The processor generates turning evaluation data related to at least one of agility and smoothness when the lean vehicle turns from the lean vehicle driving data. The memory stores the generated turning evaluation data. The economic loss related data is generated based on the lean vehicle driving data as well as the turning evaluation data related to at least one of agility and smoothness when the lean vehicle turns.
[0036] Economic loss-related data is generated based on lean vehicle driving data as well as turning evaluation data related to at least one of agility and smoothness during turning of the lean vehicle. The turning evaluation data is data reflecting the driving skill that affects the predicted driving level of the driver who drives the lean vehicle. Furthermore, by combining the agility and the smoothness, the driving tendency of the driver can be grasped. Therefore, by generating the economic loss-related data based on the lean vehicle driving data and the turning evaluation data as described above, economic loss-related data that more accurately reflects the driving skill and driving tendency can be obtained. Therefore, the lean vehicle driving data processing device can generate and output economic loss-related data that more reliably reflects the driving skill and driving tendency of the driver.

[0045] In this specification, an embodiment of a lean vehicle driving data processing device according to the present invention will be described.
[0046] In the following description, numerous specific examples are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without these specific examples.
[0047] The following disclosure is therefore to be considered as illustrative of the present invention and is not intended to limit the invention to the specific embodiments illustrated by the following drawings or description.
[0048] [Lean vehicle] In this specification, a lean vehicle is a vehicle that turns in a leaning posture. Specifically, a lean vehicle is a vehicle that, in the left-right direction of the vehicle, leans to the left when turning left and leans to the right when turning right. A lean vehicle may be a vehicle for one person or a vehicle that can accommodate multiple people. A lean vehicle may or may not have wheels. A lean vehicle may have movable parts other than wheels, such as skis. Note that a lean vehicle includes all vehicles that turn in a leaning posture, such as not only two-wheeled vehicles but also three-wheeled or four-wheeled vehicles. That is, a lean vehicle may have any number of wheels.
[0049] [Sudden movement of the vehicle] In this specification, the sudden movement of the vehicle body means a movement of the vehicle body that is faster than a normal movement. The movement of the vehicle body is determined to be a sudden movement when the value related to the movement of the vehicle body is equal to or greater than a threshold value set for many drivers, when the value related to the movement of the vehicle body is a prominent value in the data of the same driver, when it is determined that the movement has changed suddenly by fitting the waveform of the data related to the movement of the vehicle body, etc. On the other hand, the movement of the vehicle body is determined to be a non-sudden movement when the value related to the movement of the vehicle body is smaller than a threshold value set for many drivers, when the value related to the movement of the vehicle body is not prominent in the data of the same driver, when it is determined that the change is not sudden by fitting the waveform of the data related to the movement of the vehicle body, etc.
[0050] [The vehicle tilts left and right] In this specification, the lateral tilt of the vehicle body refers to a vehicle body movement in which the lateral tilt angle of the vehicle body is changing, i.e., the lateral tilt of the vehicle body refers to a vehicle body movement in which a value related to the roll motion of the vehicle body is not zero.
[0051] The left-right tilting of the vehicle body is a motion of the vehicle body that occurs when changing the traveling direction of a lean vehicle. For example, the left-right tilting of the vehicle body is a motion of the vehicle body that occurs when turning a curve or an intersection. In addition, for example, the left-right tilting of the vehicle body is a motion of the vehicle body that changes lanes or changes course within a lane. In addition, for example, the left-right tilting of the vehicle body is a motion of the vehicle body that continuously changes course to avoid a manhole cover, a stone, or the like. The left-right tilting of the vehicle body includes at least one of a sudden leaning motion to turn, a sudden raising motion after finishing a turn, and a sudden change of course.
[0052] A sudden left / right tilt of the vehicle body refers to a left / right tilt of the vehicle body in which a value related to the roll motion of the vehicle body exceeds a threshold value.
[0053] [Data showing the vehicle's left-right tilting movement] In this specification, data indicating the inclination of the vehicle body in the left-right direction means data related to the roll motion of the vehicle body. The data indicating the inclination of the vehicle body in the left-right direction may be, for example, data on the roll rate of the vehicle body, or may be data other than the roll rate related to the roll motion. The data related to the roll motion may include, for example, at least one of the following: angular acceleration (roll axis angular acceleration) when the vehicle body rotates around the roll axis, angular acceleration (yaw axis angular acceleration) when the vehicle body rotates around the yaw axis, acceleration in the left-right direction (pitch axis acceleration), and a combination of the velocity and yaw rate in the front-back direction (roll axis direction). The roll axis is an axis extending in the front-back direction with respect to the lean vehicle. The pitch axis is an axis extending in the left-right direction with respect to the lean vehicle. The yaw axis is an axis extending in the vertical direction with respect to the lean vehicle. The roll axis angular acceleration is a time differential value of the roll rate. The yaw axis angular acceleration is a time differential value of the yaw rate.
[0054] [Sudden leaning in to turn] In this specification, the sudden leaning motion for turning refers to a tilting motion of the vehicle body when the time differential value of the roll rate when the driver tilts the vehicle body to the left when the lean vehicle turns left or the time differential value of the roll rate when the driver tilts the vehicle body to the right when the lean vehicle turns right is equal to or greater than the first sudden turning threshold. Note that the sudden leaning motion for turning may be determined using a value related to the roll rate other than the time differential value of the roll rate. The sudden leaning motion for turning may be determined using, for example, a value related to the yaw rate.
[0055] [Sudden lifting motion after completing a turn] In this specification, the sudden raising operation after the end of a turn refers to a tilting operation of the vehicle body when the time differential value of the roll rate when the driver raises the vehicle body after the lean vehicle turns left or right is equal to or greater than the second sudden turn threshold value. The sudden raising operation after the end of a turn may be determined using a value related to the roll rate other than the time differential value of the roll rate. The sudden raising operation after the end of a turn may be determined using, for example, a value related to the yaw rate.
[0056] [Sudden change of course] In this specification, a sudden lane change refers to a lane change of a lean vehicle when the roll rate is equal to or greater than a threshold. The lane change refers to the motion of a lean vehicle changing lane while moving in the same direction. The lane change also includes the motion of a lean vehicle changing lanes. The sudden lane change may refer to the motion of a lean vehicle when the difference between the peak values of the roll axis angular acceleration at both the time when the vehicle body is leaned and the time when it is raised is equal to or greater than a threshold. Note that a sudden lane change may be determined using a value other than the roll rate as long as it is determined using a value related to roll motion.
[0057] [Services related to economic loss] In this specification, the service related to economic loss means a service related to economic loss in insurance, finance, rental, company assessment, etc. Specifically, the service related to economic loss includes insurance-related services such as insurance rate setting support for automobile insurance companies, finance-related services such as repayment risk prediction support for customers for financial institutions, passenger and transportation industry-related services such as employee assessment support for passenger and transportation industry operating companies, sharing or rental-related services, employee evaluation-related services such as assessment support for company employees, and B to B (Business to Business)-related services. In this specification, the economic loss does not only mean economic loss, but also includes economic benefits such as bonuses and incentives. In other words, the economic loss means economic loss or profit.
[0058] [Economic loss related data] In this specification, the economic loss related data refers to data used for the above-mentioned economic loss related services. The economic loss related data includes, for example, data related to insurance premium rates, assessment results, repayment risk prediction results, etc.
[0059] [Economic loss-related data generation model] In this specification, the economic loss related data generation model means a model that generates economic loss related data in response to a sudden movement of a vehicle body included in the lean vehicle driving data. The economic loss related data generation model includes logic, a learning model, a function, a model obtained as a result of machine learning, table data, etc. for generating economic loss related data based on at least a part of the lean vehicle driving data.
[0060] [Generating economic loss-related data in response to sudden vehicle movements] In this specification, generating economic loss-related data in response to sudden movements of the vehicle body means generating economic loss-related data by evaluating or analyzing the frequency of occurrence and / or the degree of suddenness of sudden movements of the vehicle body per unit traveling distance.
[0061] [Lean vehicle driving data] In this specification, lean vehicle driving data is data related to the driving of a lean vehicle. The lean vehicle driving data includes data indicating a sudden movement of the vehicle body. The processor generates economic loss related data used for a service related to an economic loss according to the data indicating the sudden movement of the vehicle body included in the lean vehicle driving data. The lean vehicle driving data may include data related to a sudden acceleration or deceleration in the forward / rearward direction of the lean vehicle. The lean vehicle driving data may include at least one of lean vehicle driving input data related to a driving input to the lean vehicle by a driver, lean vehicle behavior data related to the behavior of the lean vehicle, lean vehicle position data related to the driving position of the lean vehicle, and lean vehicle driving environment data related to the driving environment in which the lean vehicle drives.
[0062] [First lean vehicle driving data] In this specification, the first lean vehicle driving data means lean vehicle driving data that does not include data showing a sudden left-right tilt of the vehicle body. The first lean vehicle driving data is data obtained when the vehicle body is driven so that the left-right tilt is not abrupt, for example, when the lean vehicle is driven in a wide circle when turning at an intersection. The first lean vehicle driving data is data obtained when the vehicle body is driven so that the left-right tilt is not abrupt, for example, when the lean vehicle is driven by changing lanes with a large margin of distance or time to avoid a manhole cover or a stone.
[0063] [Second lean vehicle driving data] In this specification, the second lean vehicle driving data refers to lean vehicle driving data obtained when the lean vehicle drives the same route as the route the lean vehicle drives when acquiring the first lean vehicle driving data, during the same time period on the same date, and including data indicating a sudden left-right tilt of the vehicle body. The second lean vehicle driving data is data obtained when the lean vehicle drives such that the left-right tilt of the vehicle body is sudden, for example, when the lean vehicle drives in a tight turn when turning at an intersection. The second lean vehicle driving data is data obtained when the lean vehicle drives such that the left-right tilt of the vehicle body is sudden, for example, when the lean vehicle drives such that the lean vehicle changes course without sufficient distance or time to avoid a manhole cover or a stone.
[0064] The first lean vehicle driving data and the second lean vehicle driving data are lean vehicle driving data obtained when a lean vehicle drives the same route during the same time period on the same date, and are lean vehicle driving data that do not include sudden acceleration or deceleration of the vehicle body in the forward / rearward direction. The first lean vehicle driving data and the second lean vehicle driving data differ in whether the lean vehicle driving data includes data indicating sudden left / right tilting of the vehicle body.
[0065] [1st time slot of 1st date] In this specification, the first time period on the first date means that the date and time when the lean vehicle runs when the first lean vehicle driving data and the second lean vehicle driving data are acquired are the same time period on the same date. This is to match the driving conditions of the lean vehicle as much as possible when the first lean vehicle driving data and the second lean vehicle driving data are acquired, respectively. For example, the time period before and after sunset is not included in the same time period. The same time period is a range of time during which the same driver can drive the lean vehicle. Note that the time period means a predetermined time range on a time axis, such as one hour, two hours, etc.
[0066] [First Route] In this specification, the first route means that the route on which the lean vehicle travels when the first lean vehicle driving data and the second lean vehicle driving data are acquired is the same route. In other words, the first route means that the road on which the lean vehicle travels when the first lean vehicle driving data and the second lean vehicle driving data are acquired is the same road. This is to make the driving conditions of the lean vehicle as similar as possible when the first lean vehicle driving data and the second lean vehicle driving data are acquired.
[0067] [1 driving cycle] In this specification, one driving cycle means the running of the lean vehicle during the period from when the posture and the longitudinal speed of the lean vehicle change from a predetermined state to when they return to the predetermined state. The one driving cycle may mean, for example, the running of the lean vehicle from when the lean vehicle starts from a stopped state until it stops thereafter. The posture of the lean vehicle at the start and end of the one driving cycle may be upright or inclined. The speed of the lean vehicle at the start and end of the one driving cycle may be zero or other than zero. The one driving cycle may not include left and right turns at intersections and cornering at curves. The lean vehicle is smaller than other vehicles such as four-wheeled vehicles, and there are many opportunities to make small course changes even on straight roads. Therefore, even if the data of the one driving cycle does not include turns and cornering, the data is likely to show movements other than the straight running of the lean vehicle.
[0068] [Agility] In this specification, agility refers to the movement of a lean vehicle when the actual turning motion of the lean vehicle as it traverses a corner corresponds to a predicted turning motion based on the driver's intent to generate turning power for the lean vehicle.
[0069] [Smoothness] As used herein, smoothness refers to the behavior of a lean vehicle when the actual turning motion of the lean vehicle as it travels around a corner corresponds to the turning motion predicted based on the driver's intent. Effect of the Invention
[0070] According to one embodiment of the present invention, a lean vehicle driving data processing device can be provided that can improve the accuracy of economic loss-related data obtained based on lean vehicle driving data while increasing the design freedom of hardware resources.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0072] Hereinafter, each embodiment will be described with reference to the drawings. Note that the dimensions of components in each drawing do not faithfully represent the actual dimensions of the components and the dimensional ratios of the components.
[0073] <Embodiment 1> (Lean vehicle driving data processing device) FIG. 1 shows a schematic configuration of a lean vehicle driving data processing device 1 according to a first embodiment of the present invention. The lean vehicle driving data processing device 1 is a device that generates economic loss related data based on driving data (lean vehicle driving data) of the lean vehicle X obtained when a driver drives the lean vehicle X. The lean vehicle driving data processing device 1 may output the economic loss related data. When generating the economic loss related data based on the lean vehicle driving data, the lean vehicle driving data processing device 1 of this embodiment uses data that indicates a left-right tilting movement of the vehicle body, which is included in the lean vehicle driving data.
[0074] In this embodiment, the economic loss related data is generated in response to a sudden left-right tilt of the vehicle body. The economic loss related data is used for services related to economic loss. The economic loss related services are, for example, services related to economic loss in insurance, finance, rental, company assessment, etc. Therefore, the economic loss related data is used for, for example, insurance related services, finance related services, sharing and rental related services, employee assessment in companies, etc.
[0075] The lean vehicle driving data in this embodiment is data related to the driving of the lean vehicle X. The lean vehicle driving data is used when generating the economic loss related data. The lean vehicle driving data includes data indicating a sudden left-right tilt of the vehicle body. Data indicating a sudden left-right tilt of the vehicle body is likely to reveal differences in the driving skills and driving tendencies of the drivers of the lean vehicle X. In addition, the driving skills affect differences in the predictive driving levels of the drivers. Therefore, data indicating a sudden left-right tilt of the vehicle body is likely to reveal differences in the predictive driving levels of the drivers.
[0076] The lateral tilt of the vehicle body is a movement of the vehicle body in which the lateral tilt angle of the vehicle body is changing, i.e., the lateral tilt of the vehicle body is a movement in which a value related to the roll motion of the vehicle body is not zero.
[0077] The left-right tilting of the vehicle body is a motion of the vehicle body that occurs when changing the traveling direction of the lean vehicle X. For example, the left-right tilting of the vehicle body is a motion of the vehicle body that occurs when turning a curve or an intersection. In addition, for example, the left-right tilting of the vehicle body is a motion of the vehicle body that changes lanes or changes course within a lane. In addition, for example, the left-right tilting of the vehicle body is a motion of the vehicle body that continuously changes course to avoid a manhole cover, a stone, or the like. The left-right tilting of the vehicle body includes a sudden leaning motion to turn, a sudden raising motion after turning, or a sudden change of course.
[0078] The sudden lateral tilt of the vehicle body is, for example, the above-mentioned lateral tilt of the vehicle body, in which a value related to the roll motion of the vehicle body is equal to or greater than a threshold value. In this case, the data indicating the lateral tilt of the vehicle body is data related to the roll motion of the vehicle body.
[0079] Therefore, the lean vehicle driving data includes, for example, at least one of data related to a sudden leaning operation of the lean vehicle X to turn, data related to a sudden pulling up operation of the lean vehicle after completing a turn, and data related to a sudden change of course of the lean vehicle.
[0080] Unlike a four-wheel vehicle, a lean vehicle leans to the right when turning right and leans to the left when turning left. Therefore, when turning a lean vehicle left or right, the driver needs to perform an action of leaning the lean vehicle to turn the lean vehicle and an action of raising the lean vehicle after the lean vehicle has finished turning. In such a lean vehicle, the difference in the driver's driving skill and driving tendency is likely to be reflected in the action of leaning the lean vehicle to turn the lean vehicle and the action of raising the lean vehicle after the lean vehicle has finished turning. Therefore, from each data related to the action of leaning the lean vehicle to turn the lean vehicle and the action of raising the lean vehicle after the lean vehicle has finished turning, economic loss related data can be accurately obtained according to the driving skill and driving tendency of the driver who operates the lean vehicle. Moreover, the difference in the driver's driving skill is likely to be reflected in the difference in the level of the driver's predicted driving. Therefore, from each of the above data, economic loss related data can be obtained according to the difference in the predicted driving level of the driver.
[0081] In addition, unlike four-wheel vehicles, lean vehicles change course by tilting the body in the left-right direction. Therefore, differences in the driver's driving skills and driving tendencies are likely to be reflected in the tilt state of the body when the lean vehicle changes course. Therefore, economic loss-related data can be accurately obtained from data related to the course change of the lean vehicle according to the driving skills and driving tendencies of the driver operating the lean vehicle.
[0082] Furthermore, since a lean vehicle has smaller dimensions in the left-right direction compared to a four-wheel vehicle, the vehicle has a high degree of freedom in terms of the running position in the left-right direction. Therefore, in the case of a lean vehicle, the frequency of course changes is high. Therefore, differences in the driving skills and driving tendencies of the drivers are likely to be reflected in the course changes of the lean vehicle. Therefore, from data related to the course changes of the lean vehicle, economic loss-related data can be accurately obtained according to the driving skills and driving tendencies of the driver operating the lean vehicle.
[0083] Furthermore, as described above, differences in drivers' driving skills are likely to be reflected in differences in the drivers' levels of predictive driving, so economic loss-related data can be obtained from the above-mentioned route change-related data according to differences in the drivers' levels of predictive driving.
[0084] The lane change means an operation of a lean vehicle in which the vehicle changes course while traveling in the same direction, and includes an operation of the lean vehicle changing lanes.
[0085] The lean vehicle driving data processing device 1 has a processor 10 and a memory 20. The lean vehicle driving data processing device 1 may be a mobile terminal owned by the driver of the lean vehicle X, or may be a calculation processing device that acquires data via communication and performs calculation processing. The calculation processing device may be provided in the lean vehicle, or may be provided outside the lean vehicle.
[0086] The memory 20 may be a memory capable of temporary storage, or may be a storage medium such as a hard disk. The memory 20 may have any configuration as long as it is capable of storing data acquired or calculated by the processor 10.
[0087] The memory 20 stores lean vehicle driving data when the driver drives the lean vehicle X. In Fig. 1, the lean vehicle driving data stored in the memory 20 is indicated by D1. The economic loss related data generation model may be stored in the memory 20, or may be calculated from the lean vehicle driving data stored in the memory 20 by the processor 10 or another computing device.
[0088] The economic loss-related data generation model is configured to generate economic loss-related data to be used for services related to economic loss, based on lean vehicle driving data obtained when a driver drives a lean vehicle X. In detail, the economic loss-related data generation model generates economic loss-related data according to data indicating a sudden movement of the vehicle body, which is included in the lean vehicle driving data.
[0089] The economic loss related data generation model is configured to define the lean vehicle driving data when a driver drives a first route in a first lean vehicle during a first time period on a first date such that neither the vehicle body accelerates or decelerates in the fore-and-aft direction nor the vehicle body tilts in the left-and-right direction suddenly as first lean vehicle driving data, and define the lean vehicle driving data when the driver drives the first route in the first lean vehicle during the first time period on the first date such that the vehicle body does not accelerate or decelerate in the fore-and-aft direction suddenly and the vehicle body tilts in the left-and-right direction suddenly as second lean vehicle driving data, so that the first economic loss related data generated based on the first lean vehicle driving data and the second economic loss related data generated based on the second lean vehicle driving data are different data from each other.
[0090] The economic loss-related data generation model includes logic, a learning model, a function, a model obtained as a result of machine learning, table data, etc. for generating economic loss-related data based on at least a portion of the lean vehicle driving data.
[0091] In addition, when the change in the left-right tilting movement of the vehicle body (e.g., roll rate) is small (e.g., change due to measurement variation or error), the economic loss-related data generated by the economic loss-related data generation model may not change.
[0092] The processor 10 is, for example, a processing device used in a computer. The processor 10 may have an economic loss-related data generation model. The processor 10 may read the economic loss-related data generation model from the memory 20 or another storage device. The processor 10 may use the economic loss-related data generation model calculated by the processor 10 or another processing device.
[0093] The processor 10 acquires lean vehicle driving data and stores it in the memory 20, and generates economic loss related data by performing calculation processing using the lean vehicle driving data stored in the memory 20 and the economic loss related data generation model. The processor 10 outputs the generated economic loss related data.
[0094] 2 is a block diagram showing a schematic configuration of the processor 10. As shown in FIG. 2, the processor 10 includes an economic loss related data generating unit 11 and an output unit 12.
[0095] The lean vehicle driving data stored in the memory 20 may be acquired by, for example, a sensor. The sensor may include a device for detecting a position, such as an angle sensor including a gyro sensor, an acceleration sensor, a six-axis inertial measurement unit (IMU), an image sensor, an infrared sensor, an ultrasonic sensor, or a GPS. The sensor may be any detection device that can acquire the above-mentioned lean vehicle driving data.
[0096] The economic loss related data generating unit 11 of the processor 10 generates economic loss related data using lean vehicle driving data including data indicating left-right tilting of the vehicle body and an economic loss related data generating model. The output unit 12 of the processor 10 outputs the economic loss related data generated by the economic loss related data generating unit 11.
[0097] As described above, the lean vehicle driving data processing device 1 of this embodiment has a memory 20 that stores driving data of a lean vehicle X that leans to the left when turning left and leans to the right when turning right, and a processor 10 that generates economic loss related data based on the lean vehicle driving data stored in the memory 20 using an economic loss related data generation model that generates economic loss related data to be used for services related to economic loss in accordance with data indicating sudden movement of the vehicle body contained in the lean vehicle driving data, and outputs the generated economic loss related data.
[0098] The economic loss related data generation model is configured to define the lean vehicle driving data when a driver drives a first route in a first lean vehicle during a first time period on a first date such that neither the vehicle body accelerates or decelerates in the fore-and-aft direction nor the vehicle body tilts in the left-and-right direction suddenly as first lean vehicle driving data, and define the lean vehicle driving data when the driver drives the first route in the first lean vehicle during the first time period on the first date such that the vehicle body does not accelerate or decelerate in the fore-and-aft direction suddenly and the vehicle body tilts in the left-and-right direction suddenly as second lean vehicle driving data, so that the first economic loss related data generated based on the first lean vehicle driving data and the second economic loss related data generated based on the second lean vehicle driving data are different data from each other.
[0099] As a result, the economic loss-related data generation model can obtain economic loss-related data corresponding to sudden left-right tilting movements of the vehicle body based on data indicating the left-right tilting movements of the vehicle body contained in the lean vehicle driving data, which reflects the driving skills and driving tendencies of the driver of the lean vehicle.
[0100] The economic loss related data generation model is configured such that the second economic loss related data obtained based on the second lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body tilts sharply in the left-right direction is different from the first economic loss related data obtained based on the first lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body does not tilt sharply in the left-right direction. Therefore, the economic loss related data generation model is configured such that the second economic loss related data obtained based on the second lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body does not tilt sharply in the left-right direction is different from the first economic loss related data obtained based on the first lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body does not tilt sharply in the left-right direction. left and right Economic loss related data can be generated in response to sudden movements in the direction of inclination.
[0101] In the lean vehicle X, the driver's driving skill and driving tendency are easily reflected in a sudden left-right tilt of the vehicle body. Therefore, by using the economic loss related data generation model as described above to generate economic loss related data in response to a sudden left-right tilt of the vehicle body, it is possible to accurately obtain economic loss related data in response to the driver's driving skill and driving tendency.
[0102] In addition, by using data indicating the left-right tilting movement of the vehicle body included in the lean vehicle driving data that reflects the driving skill and driving tendency of the driver of the lean vehicle X, it is possible to suppress an increase in the amount of data to be processed compared to the case where all lean vehicle driving data is used. Therefore, it is possible to reduce the load on the hardware in the lean vehicle driving data processing device. Therefore, it is possible to increase the degree of freedom in designing the hardware resources of the lean vehicle driving data processing device.
[0103] As described above, it is possible to provide a lean vehicle driving data processing device 1 that can improve the accuracy of economic loss related data obtained based on lean vehicle driving data while increasing the degree of freedom in designing hardware resources.
[0104] <Embodiment 2> In this embodiment, the lean vehicle driving data processed by the processor 10 of the lean vehicle driving data processing device 1 includes driving data of one or more driving cycles of the lean vehicle X. In addition, the lean vehicle driving data includes at least data related to roll motion.
[0105] FIG. 3 is a diagram for explaining one driving cycle of the lean vehicle X. As shown in FIG. 3, the one driving cycle means a traveling period from when the posture and the speed in the longitudinal direction of the lean vehicle X change from a predetermined state to when they return to the predetermined state. That is, the one driving cycle means a traveling period from when the posture of the lean vehicle X is a predetermined posture and the speed in the longitudinal direction is a predetermined speed to when the posture becomes the predetermined posture and the speed becomes the predetermined vehicle speed. The predetermined posture in the one driving cycle may be an upright posture or a posture inclined in the left-right direction. The predetermined speed in the one driving cycle may be zero (stopped state) or a traveling speed other than zero.
[0106] As described above, the lean vehicle driving data includes at least data related to roll motion. Thus, the lean vehicle driving data includes data indicating a lateral tilting movement of the vehicle body. Therefore, using an economic loss related data generation model, economic loss related data corresponding to a sudden lateral tilting movement of the vehicle body can be generated based on data indicating a lateral tilting movement of the vehicle body included in the lean vehicle driving data that reflects the driving skill and driving tendency of the driver of the lean vehicle.
[0107] The data indicating the lateral tilting movement of the vehicle body may be, for example, data on the roll rate of the vehicle body, or data other than the roll rate that is related to the roll movement.
[0108] The economic loss related data generation model is generated by, for example, machine learning using training data and feature quantities as follows. Note that any form of machine learning may be used. As long as the economic loss related data generation model can be generated, the economic loss related data generation model may be generated by a method other than machine learning.
[0109] The teacher data is, for example, data having an association between the lean vehicle driving data and economic loss. That is, the teacher data is, for example, data associating the lean vehicle driving data with economic loss related data.
[0110] The feature amount includes, for example, a driving skill evaluation index, a driving event index, a vehicle behavior evaluation index, a driving distance, a driving time, a driving environment index, etc. The feature amount may include at least one of these indexes. The feature amount may not include indexes other than the driving skill evaluation index and the driving event index.
[0111] The piloting skill evaluation index is an index related to the evaluation of piloting skill. The piloting skill evaluation index is, for example, an index related to smoothness and agility. These indices are obtained based on acceleration, angular velocity, geomagnetism, and position information obtained by GPS or the like.
[0112] The driving event indexes are indexes related to sharp turns, emergency avoidance, etc. These indexes are obtained based on acceleration, angular velocity, geomagnetism, and position information by GPS or the like.
[0113] The vehicle behavior evaluation indexes are indexes related to acceleration tendency, road surface condition, lateral variability, etc. when driving in a straight line or when turning. These indexes are obtained based on acceleration, angular velocity, geomagnetism, and position information from GPS or the like.
[0114] The travel distance is obtained based on location information from a GPS, etc. The travel time is obtained based on a time stamp, etc.
[0115] The driving environment indexes are indexes related to the driving environment such as temperature, visibility distance, wind speed, amount of rain, day and night, etc. These indexes are obtained based on weather information, etc.
[0116] In this embodiment, if the driving of the lean vehicle X during a period from when the attitude and longitudinal speed of the lean vehicle X change from a predetermined state until when the driving of the lean vehicle X returns to the predetermined state is defined as one driving cycle, the first lean vehicle driving data and the second lean vehicle driving data each include data for one driving cycle or more, and the economic loss related data generation model is preferably configured to generate economic loss related data corresponding to a sudden left-right tilting movement of the vehicle body based on data indicating a left-right tilting movement of the vehicle body for one driving cycle or more included in the lean vehicle driving data so that the first economic loss related data generated based on the first lean vehicle driving data and the second economic loss related data generated based on the second lean vehicle driving data are different data from each other.
[0117] As a result, the lean vehicle driving data includes data for one or more driving cycles. Therefore, using the economic loss related data generation model, economic loss related data corresponding to a sudden left / right tilt of the vehicle body can be generated based on data indicating the left / right tilt of the vehicle body for one or more driving cycles included in the lean vehicle driving data that reflects the driving skill and driving tendency of the driver of the lean vehicle X.
[0118] Moreover, the second lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body tilts sharply in the left-right direction includes data for one or more driving cycles, and the first lean vehicle driving data obtained when the vehicle travels along the first route so that the vehicle body does not tilt sharply in the left-right direction includes data for one or more driving cycles. Therefore, economic loss related data can be generated more accurately in response to a sudden tilt of the vehicle body in the left-right direction by using the economic loss related data generation model configured so that the second economic loss related data obtained based on the second lean vehicle driving data is different from the first economic loss related data obtained based on the first lean vehicle driving data.
[0119] Furthermore, by the processor 10 generating economic loss related data based on data from the lean vehicle driving data that indicates the left-right tilting of the vehicle body, the increase in the amount of data to be processed can be suppressed more than when all of the lean vehicle driving data is used. Therefore, the load on the hardware in the lean vehicle driving data processing device can be further reduced. Therefore, the design freedom of the hardware resources of the lean vehicle driving data processing device can be further increased.
[0120] As a result of the above, it is possible to provide a lean vehicle driving data processing device that can improve the accuracy of economic loss-related data obtained based on lean vehicle driving data while increasing the design freedom of hardware resources.
[0121] In this embodiment, the first lean vehicle driving data and the second lean vehicle driving data preferably include at least data related to roll motion.
[0122] In this way, since the first lean vehicle driving data and the second lean vehicle driving data include at least data related to roll motion, the first lean vehicle driving data and the second lean vehicle driving data include data indicating a lateral tilting movement of the vehicle body. Therefore, using the economic loss related data generation model, economic loss related data corresponding to a sudden lateral tilting movement of the vehicle body can be generated based on the data indicating the lateral tilting movement of the vehicle body included in the lean vehicle driving data that reflects the driving skill and driving tendency of the driver of the lean vehicle.
[0123] <Embodiment 3> 4 is a diagram showing a schematic configuration of a lean vehicle driving data processing device 101 according to embodiment 3. The lean vehicle driving data processing device 101 of this embodiment analyzes the driving scene of the lean vehicle X based on the lean vehicle driving data, and generates economic loss related data using the analysis results. Note that, in the following, the same components as those in embodiment 1 are given the same reference numerals and their explanation is omitted, and only the parts different from embodiment 1 are explained.
[0124] The lean vehicle travel data includes at least one of data related to a sudden leaning operation for the lean vehicle X to turn, data related to a sudden raising operation of the lean vehicle X after the lean vehicle X finishes turning, and data related to a sudden change in course of the lean vehicle X. The lean vehicle travel data may include data related to a sudden acceleration of the lean vehicle X, and data related to a sudden deceleration of the lean vehicle X.
[0125] The lean vehicle driving data processing device 101 includes a processor 110 and a memory 120 .
[0126] The processor 110 analyzes driving scenes of the lean vehicle X based on the lean vehicle driving data, and generates economic loss related data for each driving scene based on the economic loss related data generation model and the lean vehicle driving data.
[0127] Fig. 5 is a block diagram showing a schematic configuration of the processor 110. As shown in Fig. 5, the processor 110 includes a lean vehicle driving data acquisition unit 111, a lean vehicle driving data analysis unit 112, an economic loss related data generation unit 113, and an output unit 114.
[0128] The lean vehicle driving data acquisition unit 111 acquires lean vehicle driving data from a sensor (not shown) or the like when the driver drives the lean vehicle X, and stores the data in the memory 120.
[0129] The lean vehicle driving data acquisition unit 111 may, for example, acquire an operation signal related to the driving of the driver of the lean vehicle X as the lean vehicle driving input data, and store it in the memory 120. Specifically, the lean vehicle driving data acquisition unit 111 may acquire data related to the driving input of the driver of the lean vehicle X, that is, data related to accelerator operation, brake operation, steering or change in center of gravity position due to change in the driver's posture, data related to operation of various switches such as a horn switch, a blinker switch, a light switch, etc., and store it in the memory 120. These data are transmitted from the lean vehicle X.
[0130] The lean vehicle driving data acquisition unit 111 may acquire, for example, data including the acceleration, speed, and angle of the lean vehicle X that change when the driver drives the lean vehicle X as lean vehicle behavior data, and store the data in the memory 120. The processor 110 acquires the lean vehicle behavior data, for example, by a gyro sensor. The lean vehicle behavior data is data that represents the behavior of the lean vehicle X that occurs when the driver accelerates or decelerates the lean vehicle X by operating the accelerator or brake, or when the driver steers the lean vehicle X or changes its attitude including changing the position of the center of gravity.
[0131] The lean vehicle traveling data acquisition unit 111 may acquire, as the lean vehicle behavior data, operations occurring in the lean vehicle X due to switch operations or the like performed by the driver on the lean vehicle X, and store the data in the memory 120. That is, the lean vehicle traveling data acquisition unit 111 may acquire, as the lean vehicle behavior data, data related to operations occurring in the lean vehicle X due to operations of various switches such as a horn switch, a blinker switch, and a lighting switch, and store the data in the memory 120. These data are transmitted from the lean vehicle X to the lean vehicle traveling data processing device 101.
[0132] The lean vehicle driving data acquisition unit 111 may acquire lean vehicle position data related to the driving position of the lean vehicle X based on, for example, information from a GPS or a communication base station of a communication mobile terminal, and store the data in the memory 120. The lean vehicle position data can be calculated by various positioning techniques, such as SLAM.
[0133] The lean vehicle driving data acquisition unit 111 may acquire the lean vehicle driving environment data from, for example, map data, and store it in the memory 120. This map data may be associated with, for example, information on road conditions, information on road traffic environments such as signals and facilities, and regulation information on road driving. The map data may also be associated with environmental data such as weather, temperature, or humidity. The map data may include information in which road information and information on road traffic environments (accompanying information on roads such as signals) are associated with regulation information on road driving.
[0134] The lean vehicle driving data acquisition unit 111 may acquire the lean vehicle driving environment data, for example, by an external environment recognition device mounted on the lean vehicle X, and store it in the memory 120. More specifically, the lean vehicle driving data acquisition unit 111 may acquire the lean vehicle driving environment data from a camera or a radar, and store it in the memory 20. The processor 110 may also acquire the lean vehicle driving environment data, for example, by a communication device, and store it in the memory 120. More specifically, the lean vehicle driving data acquisition unit 111 may acquire the lean vehicle driving environment data by a vehicle-to-vehicle communication device or a road-to-vehicle communication device, and store it in the memory 120. The processor 110 may acquire the lean vehicle driving environment data, for example, via the Internet, and store it in the memory 120. In this way, the lean vehicle driving environment data can be acquired from various means. The means for acquiring the lean vehicle driving environment data is not limited to a specific means.
[0135] The lean vehicle driving data analysis unit 112 uses the lean vehicle driving data to analyze at least one of the following: a sudden leaning operation for turning the lean vehicle X, a sudden raising operation after the turning is completed, and a sudden change of course. In more detail, the lean vehicle driving data analysis unit 112 uses the lean vehicle driving data to analyze at least one of the frequency and the degree of the at least one of the above-mentioned scenes. The lean vehicle driving data analysis unit 112 may also analyze at least one of the sudden deceleration and the sudden acceleration of the lean vehicle X.
[0136] The economic loss related data generating unit 113 generates economic loss related data using the lean vehicle driving data including data indicating the left-right tilting movement of the vehicle body in the analyzed scene and the economic loss related data generating model. The output unit 114 outputs the economic loss related data generated by the economic loss related data generating unit 113.
[0137] The configuration of the processor 110 other than the above is similar to that of the processor 10 of the first embodiment. The configuration of the memory 120 is similar to that of the memory 20 of the first embodiment.
[0138] (Analysis of lean vehicle driving data in driving scenarios) Next, the analysis of the lean vehicle driving data in a driving scene of the lean vehicle X by the processor 110 will be described with reference to Fig. 6 to Fig. 8. Note that the processor 110 does not need to analyze sudden deceleration and sudden acceleration.
[0139] 1. Sudden deceleration and acceleration The processor 110 determines the sudden deceleration and sudden acceleration of the lean vehicle X, for example, based on the acceleration in the forward and backward directions of the lean vehicle X. The processor 110 determines the sudden deceleration and sudden acceleration of the lean vehicle X using the lean vehicle driving data D1 stored in the memory 120.
[0140] 6 is a diagram showing an example of a change in acceleration in the longitudinal direction of the lean vehicle X. As shown in FIG. 6, the processor 110 determines that the lean vehicle X is suddenly decelerating when the acceleration in the longitudinal direction of the lean vehicle X is a negative value and is equal to or less than a sudden deceleration threshold. The processor 110 determines that the lean vehicle X is suddenly accelerating when the acceleration in the longitudinal direction of the lean vehicle X is a positive value and is equal to or more than a sudden acceleration threshold. The sudden deceleration threshold and the sudden acceleration threshold are stored in the memory 120.
[0141] The results of the sudden deceleration and sudden acceleration determination by the processor 110 as described above are stored in the memory 120 as data related to at least one of the frequency and the degree. The frequency is, for example, the frequency of occurrence of sudden deceleration or sudden acceleration. The degree is, for example, the ratio of the magnitude of the longitudinal acceleration to the sudden deceleration threshold in the case of sudden deceleration, or the ratio of the magnitude of the longitudinal acceleration to the sudden acceleration threshold in the case of sudden acceleration.
[0142] 2. Sudden leaning to turn and sudden raising after turning The processor 110 determines a sudden leaning operation for turning in the lean vehicle X and a sudden raising operation after the turning is completed, for example, based on a time differential value of the roll rate. The processor 110 determines a sudden leaning operation for turning in the lean vehicle X and a sudden raising operation after the turning is completed, using the lean vehicle driving data stored in the memory 120.
[0143] Fig. 7 is a diagram showing an example of changes in the roll rate and the time differential value of the roll rate of the lean vehicle X before, during, and after the lean vehicle X turns. In Fig. 7, the roll rate is indicated by a thin line, and the time differential value of the roll rate is indicated by a thick line. As shown in Fig. 7, there are peaks (black circles in the diagram) of the time differential value of the roll rate of the lean vehicle X before and after the lean vehicle X turns.
[0144] The processor 110 determines the sudden leaning operation of the lean vehicle X for turning by using the peak of the time differential value of the roll rate before the lean vehicle X turns. Specifically, the processor 110 determines that the operation of the lean vehicle X is the sudden leaning operation of the lean vehicle X for turning when the peak of the time differential value of the roll rate before the lean vehicle X turns is equal to or greater than the first sharp turn threshold. The processor 110 may determine that the operation of the lean vehicle X is the sudden leaning operation of the lean vehicle X for turning when the average value of the peak of the time differential value of the roll rate before the lean vehicle X turns is equal to or greater than the first sharp turn threshold.
[0145] The processor 110 uses the peak of the time differential value of the roll rate after the lean vehicle X has finished turning to determine whether the lean vehicle X has suddenly pulled up after the lean vehicle X has finished turning. Specifically, when the peak of the time differential value of the roll rate after the lean vehicle X has finished turning is equal to or greater than the second abrupt turning threshold, the processor 110 determines that the behavior of the lean vehicle X is a sudden pulling up behavior of the lean vehicle X after the lean vehicle X has finished turning. When the average value of the peak of the time differential value of the roll rate after the lean vehicle X has finished turning is equal to or greater than the second abrupt turning threshold, the processor 110 determines that the behavior of the lean vehicle X is a sudden pulling up behavior of the lean vehicle X after the lean vehicle X has finished turning. After you finish Lean vehicle X steep Cause It may be determined that it is a movement.
[0146] The processor 110 may use the peaks of the time differential values of the roll rates before and after the lean vehicle X turns to determine at least one of a sudden leaning operation of the lean vehicle X for turning and a sudden raising operation of the lean vehicle X after the turning is completed. The processor 110 may use the yaw rate, pitch axis acceleration, yaw axis angular acceleration, or roll axis angular acceleration instead of the roll rate to determine a sudden leaning operation for turning and a sudden raising operation after the turning is completed. The processor 110 may determine a sudden turn when the difference between the peak values of the roll rates at both the time of leaning and the time of raising is equal to or greater than a threshold value.
[0147] The results of the determination by the processor 110 of the sudden leaning operation for turning and the sudden pulling up operation after the end of the turn as described above are stored in the memory 120 as data related to at least one of the frequency and the degree. The frequency is, for example, the occurrence frequency of the sudden leaning operation for turning or the sudden pulling up operation after the end of the turn. The degree is, for example, the ratio of the magnitude of the time differential value of the roll rate to the first abrupt turn threshold in the case of the sudden leaning operation for turning, or the ratio of the magnitude of the time differential value of the roll rate to the second abrupt turn threshold in the case of the sudden pulling up operation after the end of the turn.
[0148] The processor 110 may determine at least one of a sudden leaning motion of the lean vehicle X to turn and a sudden raising motion of the lean vehicle X after the turn is completed based on, for example, the roll rate, not the time differential value of the roll rate.
[0149] 3. Sudden changes of course The processor 110 determines the sudden change in direction of the lean vehicle X based on, for example, the roll rate. The processor 110 determines the sudden change in direction of the lean vehicle X using the lean vehicle driving data stored in the memory 120.
[0150] figure 8 FIG. 1 is a diagram showing an example of a change in roll rate while a lean vehicle X is traveling. 8 As shown in FIG. 1, the processor 110 determines that the lean vehicle X has suddenly changed course when the peak value of the roll rate is equal to or greater than a threshold value. The threshold value is stored in the memory 120. The processor 110 may determine that the lean vehicle X has suddenly changed course by using the roll axis angular acceleration, the yaw rate, the pitch axis acceleration, or the yaw axis angular acceleration instead of the roll rate. The processor 110 may determine that the lean vehicle X has suddenly changed course when the difference between the peak values of the roll axis angular acceleration at both the time points when the vehicle body is leaned and when it is raised is equal to or greater than a threshold value.
[0151] The result of the processor 110's determination of an abrupt lane change as described above is stored in the memory 120 as data relating to at least one of the frequency and the degree. The frequency is, for example, the frequency of occurrence of the abrupt lane change. The degree is, for example, the ratio of the magnitude of the peak value of the roll rate to the threshold value in the case of an abrupt lane change.
[0152] The processor 110 may determine a sudden change in direction of the lean vehicle X by using data obtained by processing the peak value of the roll rate.
[0153] The lean vehicle driving data analysis unit 112 analyzes each of the above-mentioned scenes and outputs the results. The economic loss related data generation unit 113 generates economic loss related data using the judgment results of each scene by the lean vehicle driving data analysis unit 112 and an economic loss related data generation model. The economic loss related data generation model includes, for example, data that associates each scene with economic loss related data. Therefore, the economic loss related data generation unit 113 generates economic loss related data using the judgment results of each scene by the lean vehicle driving data analysis unit 112 and the economic loss related data generation model. Generative Model The economic loss related data can be generated by using the above. The output unit 114 outputs the economic loss related data generated by the economic loss related data generating unit 113.
[0154] With the above configuration, the processor 110 of the lean vehicle driving data processing device 101 uses the lean vehicle driving data of the lean vehicle X driven by the driver to analyze at least one scene of a sudden leaning operation for turning the lean vehicle X, a sudden raising operation after the turning is completed, and a sudden change of course, and generates and outputs economic loss related data using the lean vehicle driving data and an economic loss related data generation model.
[0155] As a result, economic loss related data can be obtained using lean vehicle driving data including data related to at least one of a sudden leaning operation for turning the lean vehicle X, a sudden raising operation after the turning is completed, and a sudden change of course. The above-mentioned lean vehicle driving data is likely to reflect the driving skill and driving tendency of the driver who drives the lean vehicle X. Therefore, the economic loss related data with higher accuracy that reflects the driving skill and driving tendency of the driver who drives the lean vehicle X can be obtained.
[0156] Moreover, the level of the driver's predicted driving varies depending on the driving skill of the driver of the lean vehicle. Therefore, the level of the driver's predicted driving is likely to be reflected in the sudden left-right tilt of the vehicle body. Therefore, by generating the economic loss related data according to the sudden left-right tilt of the vehicle body as described above, the economic loss related data can be accurately obtained according to the driver's predicted driving level.
[0157] The economic loss related data generation model is configured to define the lean vehicle driving data when a driver drives a first route in a first lean vehicle during a first time period on a first date such that neither the vehicle body accelerates or decelerates in the fore-and-aft direction nor the vehicle body tilts in the left-and-right direction suddenly as first lean vehicle driving data, and define the lean vehicle driving data when the driver drives the first route in the first lean vehicle during the first time period on the first date such that the vehicle body does not accelerate or decelerate in the fore-and-aft direction suddenly and the vehicle body tilts in the left-and-right direction suddenly as second lean vehicle driving data, so that the first economic loss related data generated based on the first lean vehicle driving data and the second economic loss related data generated based on the second lean vehicle driving data are different data from each other.
[0158] In addition, by analyzing at least one of the following scenes: a sudden leaning motion for turning the lean vehicle X, a sudden raising motion after the turning, and a sudden change of course, an increase in the amount of data to be processed can be suppressed compared to the case where all driving scenes are analyzed. Therefore, the load on the hardware in the lean vehicle driving data processing device 101 can be reduced. Therefore, the degree of freedom in designing the hardware resources of the lean vehicle driving data processing device 101 can be increased.
[0159] As described above, it is possible to provide a lean vehicle driving data processing device 101 that can improve the accuracy of economic loss related data obtained based on lean vehicle driving data while increasing the design freedom of hardware resources.
[0160] In addition, in this embodiment, the processor 110 uses the lean vehicle driving data to analyze at least one of the frequency and degree of sudden leaning operations to turn, sudden pulling up operations after completing a turn, and sudden course changes, and generates and outputs economic loss-related data corresponding to the analyzed scene using the lean vehicle driving data and an economic loss-related data generation model so that the data differs depending on at least one of the frequency and degree.
[0161] The lean vehicle driving data and the economic loss related data generation model each include data that better reflects the differences in driving skills and driving tendencies of the drivers who drive the lean vehicle X. Therefore, the economic loss related data generated based on the lean vehicle driving data and the economic loss related data generation model better reflects the driving skills and driving tendencies of the drivers. Therefore, the lean vehicle driving data processing device 101 can generate and output economic loss related data that more reliably reflects the driving skills and driving tendencies of the drivers.
[0162] Moreover, the predicted driving level of a driver of a lean vehicle differs depending on the driving skill of the driver. Therefore, the difference in the predicted driving level of the driver is likely to be reflected in the lean vehicle driving data and the economic loss related data generation model. Therefore, by generating economic loss related data based on the lean vehicle driving data and the economic loss related data generation model as described above, it is possible to accurately obtain economic loss related data according to the predicted driving level of the driver.
[0163] In addition, by the processor 110 analyzing at least one of the frequency and the degree of at least one of the sudden leaning motion for turning, the sudden raising motion after the turning is completed, and the sudden course change, the increase in the amount of data to be processed can be suppressed more than when all driving scenes are analyzed. Therefore, the load on the hardware in the lean vehicle driving data processing device 101 can be further reduced. Therefore, the degree of freedom in designing the hardware resources of the lean vehicle driving data processing device 101 can be further increased.
[0164] Therefore, it is possible to provide a lean vehicle driving data processing device 101 that can improve the accuracy of economic loss related data obtained based on lean vehicle driving data while increasing the design freedom of hardware resources.
[0165] <Embodiment 4> 9 is a diagram showing a schematic configuration of a lean vehicle driving data processing device 201 according to the fourth embodiment. The lean vehicle driving data processing device 201 of this embodiment analyzes the driving scene of the lean vehicle X from the lean vehicle driving data, generates turning evaluation data related to at least one of the agility and smoothness during turning of the lean vehicle X, and generates economic loss related data based on the turning evaluation data in addition to the lean vehicle driving data and the economic loss related data generation model. In the following, the same reference numerals are used for the same configuration as in the third embodiment, and the description is omitted, and only the parts different from the third embodiment are described.
[0166] The processor 210, like the processor 110 of the third embodiment, uses the lean vehicle travel data and the economic loss related data generation model to analyze at least one of the following scenes: a sudden leaning motion for turning the lean vehicle X, a sudden raising motion after the turning is completed, and a sudden change of course. The processor 210 generates turning evaluation data related to at least one of agility and smoothness during turning of the lean vehicle X from the lean vehicle travel data. The processor 210 generates economic loss related data based on the analysis result of the at least one scene, the turning evaluation data, and the economic loss related data generation model.
[0167] 10 is a diagram showing a schematic configuration of the processor 210. The processor 210 includes a lean vehicle driving data acquisition unit 211, a lean vehicle driving data analysis unit 212, an economic loss related data generation unit 213, an output unit 214, a turning time driving data extraction unit 215, and a turning evaluation determination unit 216.
[0168] The turning running data extraction unit 215 extracts the running data of the lean vehicle X during turning from the lean vehicle running data stored in the memory 220. A method of extracting the running data of the lean vehicle X during turning from the lean vehicle running data is performed, for example, by using the yaw rate of the lean vehicle X. A method of extracting the running data of the lean vehicle X during turning from the lean vehicle running data is similar to the method disclosed in, for example, International Publication No. 2021 / 079494.
[0169] The turning running data of the lean vehicle X may be extracted from the lean vehicle running data by using, for example, data related to other parameters indicating the behavior of the lean vehicle X, such as the pitch rate and roll rate of the lean vehicle X, data related to the driving input to the lean vehicle X, data related to the position of the lean vehicle X, etc. Also, the turning running data of the lean vehicle X may be extracted from the lean vehicle running data by combining a plurality of data.
[0170] The turning evaluation determination unit 216 uses the turning driving data extracted from the lean vehicle driving data by the turning driving data extraction unit 215 to generate turning evaluation data related to at least one of the agility and smoothness during turning of the lean vehicle X.
[0171] In detail, the turning evaluation determination unit 216 calculates the degree of agility using at least one low frequency band component of the roll angle and pitch angle of the lean vehicle X, for example. The turning evaluation determination unit 216 calculates a roll determination index based on the low frequency band component of the roll angle, for example, and evaluates the calculated roll determination index to perform an evaluation regarding the agility. The roll determination index is an index that scores the agility. The degree of agility is calculated based on the ratio of the agility score to an evaluation criterion.
[0172] Further, the turning evaluation determination unit 216 calculates the degree of smoothness using, for example, the yaw rate of the lean vehicle X. For example, the turning evaluation determination unit 216 calculates a yaw determination index based on the yaw rate, and evaluates the calculated yaw determination index to perform an evaluation regarding the smoothness. The yaw determination index is an index in which the smoothness is scored. The degree of smoothness is calculated as a ratio of the score of the smoothness to an evaluation criterion.
[0173] The method of generating turning evaluation data related to agility and smoothness by the turning evaluation determination unit 216 is similar to the method disclosed in International Publication No. 2021 / 079494. In International Publication No. 2021 / 079494, the agility is described as quick movement, and the smoothness is described as smooth movement.
[0174] The turning evaluation determination unit 216 may generate turning evaluation data related to agility and smoothness, or may generate turning evaluation data related to agility or smoothness. The turning evaluation determination unit 216 may generate turning evaluation data divided into four categories using the degree of agility and the degree of smoothness as disclosed in International Publication No. 2021 / 079494. The evaluation of each category in this case is disclosed, for example, in International Publication No. 2021 / 079494.
[0175] The turning evaluation data obtained by the turning evaluation determination unit 216 is stored in the memory 220.
[0176] The economic loss related data generating unit 213 generates economic loss related data based on the analysis result of the lean vehicle driving data analyzing unit 212, the turning evaluation result of the turning evaluation determining unit 216 stored in the memory 220, and the economic loss related data generating model. That is, the economic loss related data generating unit 213 generates economic loss related data based on the turning evaluation data in addition to the lean vehicle driving data and the economic loss related data generating model.
[0177] The economic loss related data generating unit 213 is configured to generate the economic loss related data based on, for example, the analysis result of the lean vehicle driving data by the lean vehicle driving data analyzing unit 212 and the turning evaluation determining unit stored in the memory 220. 216 The turning evaluation result may be applied to the economic loss related data generation model to generate economic loss related data.
[0178] The economic loss related data generation unit 213 may generate economic loss related data, for example, using data obtained by applying the analysis results of the lean vehicle driving data by the lean vehicle driving data analysis unit 212 to the economic loss related data generation model, and the turning evaluation results of the turning evaluation determination unit 216 stored in the memory 220.
[0179] The configuration of the processor 210 other than the above is similar to that of the processor 110 of the third embodiment. The configuration of the memory 220 is similar to that of the memory 120 of the third embodiment.
[0180] As described above, in this embodiment, the processor 210 generates turning evaluation data related to at least one of agility and smoothness during turning of the lean vehicle X from the lean vehicle driving data. The memory 220 stores the generated turning evaluation data. The economic loss related data is generated based on the turning evaluation data related to at least one of agility and smoothness during turning of the lean vehicle X, in addition to the lean vehicle driving data and the economic loss related data generation model.
[0181] As a result, the economic loss related data is generated based on the lean vehicle driving data, the economic loss related data generation model, and also on turning evaluation data related to at least one of agility and smoothness during turning of the lean vehicle X, so that output data can be obtained that better reflects the driving skill and driving tendency of the driver who drives the lean vehicle X. Therefore, the lean vehicle driving data processing device 201 can generate and output output data that more reliably reflects the driving skill and driving tendency of the driver.
[0182] <Other embodiments> Although the embodiment of the present invention has been described above, the above-mentioned embodiment is merely an example for carrying out the present invention. Therefore, the present invention is not limited to the above-mentioned embodiment, and the above-mentioned embodiment can be appropriately modified and carried out without departing from the spirit of the present invention.
[0183] In each of the above embodiments, the lean vehicle driving data may include, for example, lean vehicle driving input data related to a driving input to the lean vehicle by a driver, lean vehicle behavior data related to the behavior of the lean vehicle, lean vehicle position data related to the driving position of the lean vehicle, and lean vehicle driving environment data related to the driving environment in which the lean vehicle drives, or may include other data. Furthermore, the lean vehicle driving data may include one or more of the lean vehicle driving input data, the lean vehicle behavior data, the lean vehicle position data, and the lean vehicle driving environment data.
[0184] The lean vehicle driving input data is data related to the operation input of the driver when the driver drives the lean vehicle. Specifically, the lean vehicle driving input data may include data related to the accelerator operation, the brake operation, the gear shift operation (the operation of the clutch lever and the operation of the shift pedal), the steering or the change in the center of gravity position due to the change in the driver's posture. Specifically, the lean vehicle driving input data may include data related to the operation of various switches such as a horn switch, a turn signal switch, and a lighting switch. Since the lean vehicle driving input data is data related to the driving input by the driver, it more reflects the result of the driver's judgment. In a lean vehicle, there are many types of operations by the driver, and the driver has a high degree of freedom of choice when driving, so the driver's driving skill and driving tendency tend to be strongly reflected. In addition, the lean vehicle driving input data may include processed data obtained by processing data acquired from a sensor or the like. The lean vehicle driving input data may include processed data obtained by processing data acquired from a sensor or the like and other data.
[0185] The lean vehicle behavior data is data related to the behavior of the lean vehicle caused by the driving input of the driver when the lean vehicle is driven by the driver. Specifically, the lean vehicle behavior data includes, for example, the acceleration, speed, and angle of the lean vehicle that change when the driver drives. In other words, the lean vehicle behavior data is data that represents the behavior of the lean vehicle that occurs when the driver accelerates or decelerates the lean vehicle by operating the accelerator, brake, or shifts gears, or when the driver steers the lean vehicle or changes its posture, including changing the center of gravity.
[0186] Furthermore, as described above, the lean vehicle behavior data may include not only data related to the acceleration, speed, and angle of the lean vehicle, but also operations occurring in the lean vehicle due to switch operations performed by the driver on the lean vehicle. That is, the lean vehicle behavior data includes data related to operations occurring in the lean vehicle due to operations of various switches such as a horn switch, a turn signal switch, and a light switch. The lean vehicle behavior data strongly reflects the results of the driver's driving input. Therefore, the lean vehicle behavior data also tends to strongly reflect the driver's driving skills and driving tendencies. The lean vehicle behavior data may also include processed data obtained by processing data acquired from a sensor or the like. The lean vehicle behavior data may also include processed data obtained by processing data acquired from a sensor or the like and other data.
[0187] The lean vehicle position data is data related to the running position of the lean vehicle. For example, the lean vehicle position data can be detected based on information from a GPS or a communication base station of a communication mobile terminal. The lean vehicle position data can be calculated using various positioning techniques, SLAM, and the like. The lean vehicle position data strongly reflects the results of the driver's driving input, which strongly reflects the driver's driving skill and driving tendency. Therefore, the lean vehicle position data also tends to strongly reflect the driver's driving skill and driving tendency. In addition, the lean vehicle position data may include processed data obtained by processing data acquired from a sensor or the like. The lean vehicle position data may include processed data obtained by processing data acquired from a sensor or the like and other data.
[0188] The lean vehicle driving environment data includes, for example, map data. The map data may be associated with, for example, information on road conditions, information on road traffic environments such as signals and facilities, and regulation information on road driving. The map data may also be associated with environmental data such as weather, temperature, and humidity. The lean vehicle driving environment data, together with the lean vehicle driving input data, the lean vehicle behavior data, and the lean vehicle position data, can be used to analyze the driver's driving skills and driving tendencies.
[0189] The information on road conditions includes information on roads (areas) in congested environments, such as frequent traffic jams and many parked vehicles. This information can be combined with the time of day to improve the accuracy of the information. The information on road conditions also includes information on roads that are prone to flooding when a squall occurs.
[0190] The lean vehicle driving environment data may include processed data obtained by processing data acquired from a sensor, etc. The lean vehicle driving environment data may include processed data obtained by processing data acquired from a sensor, etc. and other data.
[0191] The lean vehicle driving environment data is considered to be an example of external stress that the driver receives. The lean vehicle driving environment data influences the driver's judgment. The lean vehicle driving environment data influences the driver's driving. Therefore, by using the lean vehicle driving environment data, the driver's driving skills and driving tendencies are more likely to be reflected in the lean vehicle driving data. In addition, by using the lean vehicle driving environment data, the purpose and frequency of use of the lean vehicle are affected, so the driver's driving skills and driving tendencies are more likely to be reflected in the lean vehicle driving data.
[0192] The lean vehicle driving environment data can be acquired from various means. The means for acquiring the lean vehicle driving environment data is not limited to a specific means. For example, the means for acquiring the lean vehicle driving environment data is an external environment recognition device mounted on the lean vehicle. More specifically, the means for acquiring the lean vehicle driving environment data is a camera, a radar, or the like. Also, for example, the means for acquiring the lean vehicle driving environment data is a communication device. More specifically, the means for acquiring the lean vehicle driving environment data is a vehicle-to-vehicle communication device, a road-to-vehicle communication device. The lean vehicle driving environment data can also be obtained, for example, via the Internet.
[0193] In each of the above embodiments, the lean vehicle driving data may include data related to sudden acceleration of the lean vehicle and data related to sudden deceleration of the lean vehicle.
[0194] Unlike a four-wheel vehicle, the brakes of a lean vehicle include a front wheel brake operator that operates the front wheel brakes and a rear wheel brake operator that operates the rear wheel brakes. Therefore, in a lean vehicle, the driver needs to adjust the braking force of both the front wheel brakes and the rear wheel brakes. In such a lean vehicle, differences in the driver's driving skills and driving tendencies are likely to be reflected in the deceleration of the lean vehicle. Therefore, from data related to the deceleration of the lean vehicle, it is easy to obtain a correlation between the driver operating the lean vehicle and economic loss.
[0195] In addition, the weight of a lean vehicle is generally lighter than that of a four-wheel vehicle. Therefore, in a lean vehicle, the operation state of the accelerator operator by the driver is likely to be reflected in the acceleration. Therefore, differences in the driver's driving skills and driving tendencies are likely to be reflected in the acceleration of the lean vehicle. Therefore, from data related to the acceleration of the lean vehicle, it is easy to obtain a correlation between the driver who operates the lean vehicle and economic loss.
[0196] In each of the above-described embodiments, the economic loss-related data output from the lean vehicle driving data processing device 1, 101, 201 is used for services related to economic loss. However, the economic loss-related data output from the lean vehicle driving data processing device may be used in combination with data related to other information. The economic loss-related data may be used in combination with data related to information such as, for example, theft prevention of the lean vehicle, abnormalities of the lean vehicle, breakdowns of the lean vehicle, maintenance of the lean vehicle, collision prevention, improvement of the driving environment, route guidance, and presentation of information to the driver.
[0197] In each of the above embodiments, the lean vehicle driving data processing device 1, 101, 201 generates economic loss related data based on the lean vehicle driving data using an economic loss related data generation model. The economic loss related data generation model may generate the economic loss related data using a proportion of sudden left-right tilting of the vehicle body in the lean vehicle driving data. The economic loss related data generation model may generate the economic loss related data using a proportion of non-abrupt left-right tilting of the vehicle body in the lean vehicle driving data.
[0198] In the first embodiment, the lean vehicle driving data is stored in the memory 20. However, the lean vehicle driving data may be acquired by a lean vehicle driving data acquisition unit included in the processor. In this case, the lean vehicle driving data acquisition unit may acquire the lean vehicle driving data via a sensor. The acquired lean vehicle driving data may be stored in the memory.
[0199] In the second embodiment, the lean vehicle driving data, the first lean vehicle driving data, and the second lean vehicle driving data each include data for one driving cycle or more. However, at least one of the lean vehicle driving data, the first lean vehicle driving data, and the second lean vehicle driving data may include data for less than one driving cycle.
[0200] In the second embodiment, the economic loss related data generation model is configured to generate economic loss related data corresponding to a sudden left-right tilt of the vehicle body based on data indicating a left-right tilt of the vehicle body for one driving cycle or more included in the lean vehicle driving data, so that the first economic loss related data generated based on the first lean vehicle driving data and the second economic loss related data generated based on the second lean vehicle driving data are different data from each other. However, the economic loss related data generation model may be configured to generate economic loss related data corresponding to a sudden left-right tilt of the vehicle body based on data indicating a left-right tilt of the vehicle body for a period shorter than one driving cycle included in the lean vehicle driving data.
[0201] In the second embodiment, the lean vehicle driving data processed by the processor 10 of the lean vehicle driving data processing device 1 includes driving data of one or more driving cycles of the lean vehicle X. Similarly, in the first embodiment, the lean vehicle driving data processed by the processor 10 of the lean vehicle driving data processing device 1 may include driving data of one or more driving cycles of the lean vehicle X, or may include driving data shorter than one driving cycle.
[0202] In the third embodiment, the processor 110 of the lean vehicle driving data processing device 101 uses the lean vehicle driving data to analyze at least one of the frequency and degree of sudden leaning operations to turn, sudden pulling up operations after completing a turn, and sudden course changes, and uses an economic loss related data generation model to generate and output economic loss related data corresponding to the analyzed scene, which differs depending on at least one of the frequency and degree.
[0203] However, the processor may analyze with respect to parameters other than frequency and severity, and generate and output economic loss related data according to the analyzed scene such that the parameters vary.
[0204] In the third embodiment, the lean vehicle driving data processing device 101 analyzes at least one of the following scenes: a sudden leaning motion for turning a lean vehicle, a sudden raising motion after the turning is completed, and a sudden change of course, and generates and outputs economic loss related data. However, the lean vehicle driving data processing device may analyze the lean vehicle driving data in combination with other data to generate economic loss related data.
[0205] In the third embodiment, the processor 110 includes a lean vehicle driving data acquisition unit 111. However, the processor may not include the lean vehicle driving data acquisition unit. In this case, the processor may read the lean vehicle driving data stored in the memory.
[0206] In the fourth embodiment, the lean vehicle driving data processing device 201 analyzes the driving scene of the lean vehicle X from the lean vehicle driving data, generates turning evaluation data related to at least one of the agility and smoothness during turning of the lean vehicle X, and generates economic loss related data based on the turning evaluation data in addition to the lean vehicle driving data and the economic loss related data generation model. However, the lean vehicle driving data processing device may generate economic loss related data based on the lean vehicle driving data, the economic loss related data generation model, and the turning evaluation data without analyzing the driving scene of the lean vehicle X.
