[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0010] (Example of vehicle information management system configuration) 1 shows an example of the configuration of a vehicle information management system SY according to an embodiment. The vehicle information management system SY includes one or more vehicles 1 and an information processing device 2.

[0011] The vehicle 1 includes wheels 101, a steering device 102, a power source 103, a power transmission mechanism 104, and a control unit 105. The vehicle 1 is a saddle-type vehicle, and is a motorcycle here, but the number of wheels 101 is not limited to this example. In another embodiment, the vehicle 1 may be a passenger car.

[0012] The steering device 102 is configured to be capable of changing the direction of the wheels 101 (typically the front wheels). This allows the driver to perform steering operations. In this embodiment, a handlebar is used to realize this, but in other embodiments, other operators such as a steering wheel, a switch, a lever, etc. may be used.

[0013] Here, an internal combustion engine is used as the power source 103, but other units capable of generating power, such as an electric motor, may be used. The power transmission mechanism 104 is configured to be capable of transmitting the power (rotation) of the power source 103 to the wheels 101 (typically the rear wheels). The control unit 105 controls the power transmission mechanism 104, and as will be described in detail later, this makes it possible to change the transmission ratio of power from the power source 103 to the wheels 101.

[0014] A plurality of contact portions 19 are provided on the body of the vehicle 1. Each contact portion 19 is installed at a position where the driver of the vehicle 1 comes into contact with or approaches the contact portion 19. For example, a certain contact portion 19 (referred to as "contact portion 19a" for the sake of distinction) is installed on the steering device 102, such as the upper surface of the grip portion of the handlebar, the brake lever, or the like.

[0015] Vehicle 1 further includes a knee-grip portion 106, a fuel tank 107, a crankcase 108, and a seat 109. Knee-grip portion 106 is a portion where a driver holds the vehicle body between his / her knees in vehicle 1, which is a saddle-type vehicle. Fuel tank 107 stores fuel and is a portion where the driver's body may come into contact. Crankcase 108 contains power source 103 and is a portion where the driver's legs may come into contact. Seat 109 is a portion where the driver sits.

[0016] In this embodiment, other contact portions 19 are also provided on the knee grip portion 106, fuel tank 107, crankcase 108, and seat 109 (for the sake of distinction, they are referred to as "contact portion 19b," "contact portion 19c," "contact portion 19d," and "contact portion 19e," respectively). All of contact portions 19b to 19e have the same configuration as contact portion 19a. In other embodiments, some or all of contact portions 19b to 19e may be omitted.

[0017] In addition, the vehicle 1 further includes a notification unit 11 and a calculation device 12, the details of which will be described later. The notification unit 11 is configured to be capable of notifying the driver of predetermined information. The calculation device 12 is configured to be capable of executing calculation processing for realizing the functions of the vehicle information management system SY. In this embodiment, the notification unit 11 and the calculation device 12 are installed in the body of the vehicle 1, but in other embodiments, the notification unit 11 and / or the calculation device 12 may be installed separately from the body. For example, the notification unit 11 may be installed in a terminal that is detachable from the body, a terminal that is wearable by the driver, or the like.

[0018] The information processing device 2 includes a CPU (Central Processing Unit) 21, a memory 22, and a communication interface 23. With such a configuration, the information processing device 2 communicates with each vehicle 1 via the network NT, and also receives the calculation results of the calculation device 12 and generates map data based on the calculation results, as will be described in detail later.

[0019] (Functions of the computing device) 2 shows an example of the configuration of the arithmetic device 12. The arithmetic device 12 is configured to be electrically connectable to each of the multiple contact units 19. A known wiring unit such as a wire harness may be used for each of these connections. The arithmetic device 12 includes a signal output unit 121, a detection unit 122, a calculation unit 123, a determination unit 124, and an evaluation unit 125.

[0020] The signal output unit 121 is configured to be able to output an electric signal to each of the contact parts 19. In this embodiment, the signal output unit 121 includes a capacitor 121C and a switch 121W. A plurality of capacitors 121C and switches 121W may be provided to correspond to the plurality of contact parts 19. The capacitor 121C holds a voltage to be supplied to the corresponding contact part 19. The switch 121W is configured to be able to electrically connect the capacitor 121C to the corresponding contact part 19. For example, before outputting an electric signal, the switch 121W connects a predetermined battery 121B and the capacitor 121C to cause the capacitor 121C to hold a voltage, and connects the capacitor 121C to the corresponding contact part 19 when outputting an electric signal.

[0021] With this configuration, the signal output unit 121 outputs the voltage held in the capacitor 121C as the above-mentioned electrical signal to the corresponding contact unit 19. The signal output unit 121 is not limited to this configuration, and may be configured to output a voltage showing a predetermined waveform. Therefore, the electrical signal output by the signal output unit 121 may be a step pulse voltage or a sine wave voltage. Alternatively, a predetermined current may be output to the corresponding contact unit 19 as the above-mentioned electrical signal.

[0022] The contact portion 19 includes terminals Ta and Tb. An impedance based on the driver's contact state with the contact portion 19 and the degree of equipment of the driver can be formed between the terminals Ta and Tb. The voltage output from the capacitor 121C via the switch 121W is input to the terminal Ta, and a voltage according to the driver's contact state with the contact portion 19 is output from the terminal Tb. For example, when the driver is in contact with the contact portion 19, a voltage according to the degree of equipment of the driver is output from the terminal Tb, as will be described later in detail. On the other hand, when the driver is not substantially in contact with the contact portion 19, the voltage output from the terminal Tb is substantially 0 [V (volts)]. In this embodiment, the detection value of the detection portion 122 described later is expressed as impedance, but it may be a resistance value.

[0023] The detection unit 122 is connected to at least two of the multiple contact parts 19, obtains the impedance between them as a detection value, and can detect that the driver has entered the vehicle based on the detection value. For example, some impedance may be formed between the terminal Ta of the contact part 19a installed on the steering device 102 and the terminal Ta of the contact part 19e installed on the seat 109. Therefore, the detection unit 122 can detect that the driver has entered the vehicle based on the impedance or a change in the impedance. As another example, the detection unit 122 may detect that the driver has entered the vehicle based on the impedance between the terminals Ta of the contact parts 19a installed on each of a pair of left and right grip parts of the handlebar of the steering device 102.

[0024] The calculation unit 123 is configured to be able to calculate the impedance between the terminals Ta and Tb for each contact portion 19. In this embodiment, after a voltage is supplied from the capacitor 121C to the contact portion 19 via the switch 121W, the calculation unit 123 calculates the impedance between the terminals Ta and Tb based on the voltage output from the contact portion 19.

[0025] As shown in the schematic diagram, the impedance between the terminals Ta and Tb includes an inductance L1, a capacitance C1, and a resistance R1. These components of inductance L1, capacitance C1, and resistance R1 can be calculated based on the voltage input to the contact portion 19 and the voltage output from the contact portion 19 under a predetermined analytical model.

[0026] The calculation by the calculation unit 123 can also be used during detection by the detection unit 122. That is, the detection unit 122 can calculate the impedance between two of the multiple contact parts 19 in the same procedure as the calculation unit 123, and detect that the driver has entered the vehicle based on the calculation result.

[0027] The determination unit 124 is configured to be able to determine the degree of equipment of the driver, and determines the degree of equipment of the driver based on the response from the contact unit 19 to the electric signal output from the signal output unit 121. The equipment of the driver includes, for example, gloves (rider gloves, etc.), clothes (rider jacket, rider pants, etc.), and shoes (rider boots, etc.). For example, the determination unit 124 determines that the driver is lightly equipped as the value of the impedance between the terminals Ta and Tb, generally the absolute value of the composite impedance at a predetermined frequency, becomes smaller.

[0028] In the following description, the degree of equipment of the driver may be simply expressed as a "degree." Also, the determination of the degree may be simply expressed as a "determination."

[0029] In this embodiment, the determination unit 124 executes the above-mentioned determination at a predetermined cycle based on the calculation result of the calculation unit 123, but is not limited to this. For example, in another embodiment, the determination unit 124 may execute the determination in response to input of an operation (e.g., an acceleration operation, a deceleration operation, a steering operation, etc.) by the driver to the vehicle 1.

[0030] In addition, in this embodiment, the determination unit 124 starts the above-mentioned determination based on the detection result of the detection unit 122, but is not limited to this. For example, in another embodiment, the determination unit 124 may start the determination in response to input of another operation (e.g., a start-up operation, etc.) to the vehicle 1.

[0031] As described above, the impedance between the terminals Ta and Tb includes the inductance L1, the capacitance C1, and the resistance R1, but the arrangement of these is not limited to the illustrated embodiment and can be changed according to the analysis model of the calculation unit 123. For example, for the contact portion 19a installed on the steering device 102, when the determination unit 124 determines only the presence or absence of gloves as equipment of the driver, the calculation unit 123 may calculate only the resistance R1 between the terminals Ta and Tb. Also, for example, when the determination unit 124 determines the thickness of gloves, the calculation unit 123 may further calculate the inductance L1 and / or the capacitance C1 between the terminals Ta and Tb.

[0032] The determination unit 124 can determine the degree of equipment of the driver based on the calculation result of the calculation unit 123, that is, based on the response (output voltage) from each of the multiple contact units 19, with the above-mentioned configuration.

[0033] The determination unit 124, for example: Based on the response from the contact portion 19a installed on the steering device 102, it is possible to determine the presence or absence of rider gloves, the thickness of the rider gloves, etc.; Based on a response from the contact portion 19b installed on the knee grip portion 106, it is possible to determine the presence or absence of rider pants, the thickness of the rider pants, etc.; Based on the response from the contact portion 19c installed on the fuel tank 107, it is possible to determine the presence or absence of a rider jacket, the thickness of the rider jacket, etc.; The presence or absence of a rider boot, the thickness of the rider boot, etc. can be determined based on a response from the contact portion 19d installed on the crankcase 108; and Based on the response from a contact portion 19e provided on the seat 109, it is possible to determine the presence or absence of rider pants, the thickness of the rider pants, etc.

[0034] Additionally, the determination unit 124 may further determine whether the rider is gripping both of the pair of grip portions on the left and right of the handlebars based on the response from the contact portion 19a, thereby making it possible to determine whether the rider is performing an appropriate driving operation. In addition, the contact portion 19a may include a temperature detection element, thereby making it possible to increase the accuracy of determining whether or not the rider is wearing gloves, the thickness of the rider's gloves, etc.

[0035] Here, even if the degree of equipment of the driver does not change, the response from each contact unit 19 may vary with time. This can be said to indicate that the driving posture of the driver changes with time. In this embodiment, since the determination unit 124 executes the determination at a predetermined period, the evaluation unit 125 can evaluate the degree of fatigue of the driver by calculating the transition of the determination result of the determination unit 124 with the passage of time based on the responses from each of the multiple contact units 19.

[0036] The evaluation unit 125 may, for example: Based on the response from the contact portion 19a installed on the steering device 102, the manner in which the driver grips the grip portion of the handlebars can be determined; The position of the driver's knees, etc. can be determined based on a response from the contact portion 19b installed in the knee grip portion 106; Based on the response from the contact portion 19c installed on the fuel tank 107, the driver's posture, etc. can be determined; The position of the driver's legs, etc. can be determined based on a response from the contact portion 19d installed on the crankcase 108; and Based on the response from the contact portion 19e installed on the seat 109, the manner in which the driver is seated can be determined.

[0037] Generally, the detection unit 122, the calculation unit 123, the determination unit 124, and the evaluation unit 125 can all be realized by a predetermined calculation process. Therefore, in this embodiment, the detection unit 122, the calculation unit 123, the determination unit 124, and the evaluation unit 125 each include a CPU and a memory, and each function can be realized by the CPU expanding and executing a predetermined program on the memory. Also, some / all of the functions of the detection unit 122, the calculation unit 123, the determination unit 124, and the evaluation unit 125 may be realized by execution by a single CPU.

[0038] The functions of the detection unit 122, calculation unit 123, determination unit 124, and evaluation unit 125 may be realized by a semiconductor device such as an ASIC (application specific integrated circuit), and in that case, some or all of them may be configured in a single semiconductor package. That is, the functions of the detection unit 122, calculation unit 123, determination unit 124, and evaluation unit 125 can be realized by either hardware or software.

[0039] Referring again to FIG. 1, the notification unit 11 can notify the driver based on the determination result of the determination unit 124 (the degree of equipment of the driver) and / or the evaluation result of the evaluation unit 125 (the degree of fatigue of the driver). For example, if the standard of the degree of equipment of the driver is not met, the notification unit 11 can notify the driver to recommend a review of the equipment. Also, if the degree of fatigue of the driver is greater than a standard value, the notification unit 11 can notify the driver to recommend a rest. Alternatively / additionally, if the degree does not meet the standard and the inclination of the vehicle body during cornering is greater than a predetermined angle, the notification unit 11 can notify the driver of this, for example, can notify the driver to recommend a shallow bank angle and / or deceleration. These notifications may be realized by audio guidance, and in that case, for example, a sound source as the notification unit 11 may be built into the driver's helmet.

[0040] Alternatively / additionally, the control unit 105 can change the control mode of the power transmission mechanism 104 based on the degree, for example, can control the timing of changing the power transmission ratio from the power source 103 to the wheels 101. According to these modes, it may be possible to realize appropriate driving of the vehicle 1.

[0041] As described above, according to this embodiment, the signal output unit 121 outputs an electric signal to the contact unit 19, and the degree of equipment of the driver is determined based on the response from the contact unit 19 to the electric signal. Since an impedance according to the degree of equipment of the driver can be formed in the contact unit 19, it becomes possible to determine the degree of equipment of the driver based on the response from the contact unit 19, and thus it becomes possible to detect the state of the driver with high accuracy. In this embodiment, a saddle-type vehicle is exemplified as the vehicle 1, but the contents of this embodiment can be applied to other vehicles, and the same can be said about other passengers riding with the driver.

[0042] (Example of services provided by vehicle information management systems) 1 again, the information processing device 2 communicates with each vehicle 1 via the network NT, receives the calculation results of the calculation device 12, and generates map data based on the calculation results. The generation of the map data can be realized by the CPU 21 expanding and executing a predetermined program on the memory 22. For example, the information processing device 2 can generate map data indicating the distribution of the equipment levels of the drivers of a plurality of vehicles 1 based on the judgment results for those vehicles 1. Furthermore, the information processing device 2 can generate map data indicating the distribution of the fatigue levels of the drivers of a plurality of vehicles 1 based on the evaluation results for those vehicles 1.

[0043] Either or both of these map data can be used for a predetermined service, regardless of whether the content of the service is tangible or not, and examples of the service include sales services, rest services, and the like.

[0044] In this specification, the embodiment in which the degree of equipment of the driver and the degree of fatigue of the driver are evaluated is exemplified, but other states of the driver (concentration, physical condition, and other conditions) may be evaluated. In addition, although the contact portion 19e is provided on the seat 109, if the vehicle 1 is a two-seater, the contact portion 19e may be provided on the front portion (driver's seat) and the rear portion (passenger's seat) of the seat 109. In this case, the driving behavior can also be evaluated.

[0045] In the above description, for ease of understanding, each element is indicated by a name related to its function, but each element is not limited to having the content described in the embodiment as its main function, and may have it as an auxiliary function. Therefore, each element is not strictly limited to the expression, and the expression can be replaced with a similar expression. In the same spirit, the expression "apparatus" may be replaced with "unit," "component, piece," "member," "structure," "assembly," etc., or may be omitted.
