Embodiment 1.
An information management system according to Embodiment 1 will be described below.

<Configuration of information management system>
A configuration of an information management system according to Embodiment 1 will be described.
FIG. 1 is a diagram showing a mounting state of an information management system according to Embodiment 1 of the present invention on a motorcycle. FIG. 2 is a diagram showing the system configuration of the information management system according to Embodiment 1 of the present invention. FIG. 3 is a diagram for explaining the definition of the inclination angle of the motorcycle.

As shown in FIGS. 1 and 2, the information management system 1 is mounted on a motorcycle 100. FIG. The information management system 1 includes at least a running state detection unit (IMU) 11 that detects the running state of the motorcycle 100 , a processing unit (ECU) 20 , and information transmission devices 30 and 50 .

The information management system 1 acquires event information to be transmitted to the rider while the motorcycle is running, and uses the information transmission devices 30 and 50 to control the transmission of the event information to the rider. The processing unit 20 receives incoming information from a mobile phone or the like, fuel level warning information that warns that the remaining fuel level is low, and tire pressure warning information that warns that the tire pressure is low. , that is, information that does not depend on the output of the running state detection device 11 , and outputs control commands to the information transmission devices 30 and 50 .
The processing unit 20 includes, for example, the output of the running state detection device 11 for acquiring the running state information of the motorcycle 100 during running, various detection devices (not shown) for acquiring the rider's operating state information, and the like. Output is also entered. Each part of the information management system 1 may be used exclusively for the information management system 1, or may be shared with other systems.

The running state detection device 11 includes, for example, a 3-axis gyro sensor and a 3-direction acceleration sensor, and outputs the detected inertia to the processing unit 20 . The running state detection device 11 may detect other physical quantities substantially convertible to the inertia occurring in the motorcycle 100 . In addition, the traveling state detection device 11 can acquire posture information related to the inclination angle θL of the motorcycle 100 and deceleration information related to deceleration that occurs in the motorcycle. It may be a speed sensor, a yaw rate sensor or a combination thereof.

A mobile phone 40 that outputs incoming call information, a remaining fuel warning device 70 that outputs remaining fuel warning information, and a tire pressure warning device 80 that outputs tire pressure warning information are each electrically connected to a processing unit via a wired or wireless connection. It is possible to send a signal. These devices applicable to the present invention have a common feature of outputting information that does not depend on the output of the driving state detection device 11. In addition to the above-described devices, for example, a winker, a brake light, etc. It also includes a lamp failure detection device that outputs an output when a failure such as disconnection occurs in the lighting device. Hereinafter, these devices will be collectively called an event information transmission device. Further, the event information notified via the mobile phone 40 is not limited to incoming call information, and may include incoming e-mail and new arrival news.

The processing unit 20 includes an acquisition unit 21 , a priority evaluation unit 22 , a driving load state determination unit 23 , a priority determination unit 24 and a control unit 25 . Each section of the processing unit 20 may be provided collectively in one housing, or may be provided separately in a plurality of housings. Further, part or all of the processing unit 20 may be configured by, for example, a microcomputer, a microprocessor unit, etc., or may be configured by an updatable unit such as firmware, or may be configured by a command from a CPU or the like. It may be a program module or the like executed by.

While the motorcycle 100 is running, the acquisition unit 21 receives the output of the event information transmission device and acquires the event information. Then, the priority evaluation unit 22 evaluates the transmission priority of the event information acquired by the acquisition unit 21 . Specifically, the priority of the information to be notified to the rider is divided into levels according to the priority. For example, incoming call information, which is event information that does not directly affect the running state of the motorcycle, and information indicating a problem with a lamp, is given a relatively low priority, and event information that can affect the running state of the motorcycle is given a relatively low priority. Certain fuel level warning information and tire pressure warning information may be given higher priority.

The acquisition unit 21 acquires attitude information related to the inclination angle θL of the motorcycle 100 based on the output of the running state detection device 11 . The posture information related to the inclination angle θL may be information of the inclination angle θL itself, or other physical quantities that can be substantially converted to the inclination angle θL (for example, the yaw rate occurring in the motorcycle 100, the lateral acceleration, etc.). The inclination angle θL is defined as an inclination angle in the roll direction of the motorcycle 100 with respect to the upright state of the motorcycle 100 (see FIG. 3).

Further, the acquisition unit 21 may acquire deceleration information related to the deceleration of the motorcycle 100 based on the output of the running state detection device 11 . The deceleration information related to deceleration may be information on the deceleration itself of the motorcycle, or may be other physical quantity that can be substantially converted to deceleration. For example, the value of the wheel speed sensor may be obtained and the calculated value may be used in a known method to obtain the deceleration information of the motorcycle.

The driving load state determination unit 23 determines whether or not there is a driving load state of the rider based on the driving state information such as the posture information and the deceleration information acquired by the acquisition unit 21 . Specifically, the presence or absence of the load operation state may be determined by comparing the inclination angle θL as posture information with a predetermined limit inclination angle θLth1. The absolute value of deceleration |Dec| as the deceleration information may be compared with the absolute value of limit deceleration |Dec_th1| to determine the presence or absence of the load operation state.

Based on the priority level of the event information evaluated by the priority evaluation unit 22 and the driving load state determined by the driving load state determination unit 23, the priority determination unit 24 determines whether the event information should be transmitted to the rider. make a decision as to whether Specifically, the priority evaluation unit 22 may compare the tagged priority level Prio_Lv with the limit priority level Prio_L1 to determine whether event information should be transmitted to the rider. Also, the limit priority level Prio_L1 may be a fixed value, or may be variable according to the inclination angle θL and the deceleration Dec, which are the running state information acquired by the acquisition unit 21 . In this way, it is possible to output the event information to the information transmission device in accordance with the priority of the event information, so that necessary information can be quickly transmitted to the rider.

The control unit 25 controls the output of the event information acquired by the acquisition unit to the information transmission device according to the input from the driving load state determination unit or the priority determination unit. Output control may be ON/OFF control of whether or not to output, or control to adjust the mode of output. For example, it may be a control that adjusts the output of display brightness, sound volume, and vibration frequency individually or simultaneously. "Changing the output mode" in the present invention is a concept including both the aforementioned ON/OFF control and control for adjusting the output mode.

The communication unit 26 acquires a control signal from the control unit 25 and wirelessly communicates with the information transmission device. Wireless communication may take place according to a predetermined short-range communication standard (eg, Bluetooth®) in a known manner.

The information transmission device may transmit information to the rider by means of the display device 30 (i.e., perception using the visual organ as a sensory organ), and the audio device 50 (i.e., perception using the auditory organ as a sensory organ). Information may be transmitted to the rider by a vibrating device (that is, perception in which the tactile organs are used as sensory organs), or a combination of these may transmit information to the rider. It may be transmitted.
Specifically, the information transmission device is a speaker, display, lamp, vibrator, or the like. FIG. 1 shows an example in which a motorcycle 100 is provided with a display device 30 as an information transmission device, and a smart helmet 60 is provided with an acoustic device 50 as an information transmission device. Further, the information transmission device may be composed of one output device, or may be composed of a plurality of output devices of the same type or different types. The plurality of output devices may be provided integrally or may be provided separately.

The processing unit 20 executes the operation flow shown in FIG. 4 while the motorcycle 100 is running.

(Event information acquisition step)
In step S101, the acquisition unit 21 acquires event information to be notified to riders.

(Evaluation step)
In step S102, the priority evaluation unit 22 processes the event information acquired in step S101, and evaluates transmission priority as information to be notified to the rider. The evaluation of transmission priority may be divided into a plurality of levels from the viewpoint of whether or not the event information acquired by the event acquisition unit directly affects the running of the motorcycle. For example, if the event information is incoming call information notifying that a mobile phone has received an incoming call while the motorcycle is running, the incoming call information does not directly affect the running of the motorcycle, so it has a relatively low priority. to give On the other hand, if the event information is fuel level warning information that warns that the remaining fuel level is low while the motorcycle is running or tire pressure warning information that warns that the tire pressure is low, the event information is immediately Even if it does not affect the running of the motorcycle, it may affect the running of the motorcycle in the near future, so a relatively high priority is given. The data for which the priority has been evaluated is stored in a storage unit (not shown) after being tagged with the corresponding priority.

(Load operation state determination step)
In step S103, the traveling state information such as the attitude information of the motorcycle or the deceleration information of the motorcycle is acquired from the traveling state detection device. Also, in step S104, the driving load state determination unit 23 compares the driving state information acquired in step S103 with a threshold to determine whether or not the rider is in a driving load state.

Specifically, in step S104, if the information acquired in step S103 is the posture information, the driving load state determination unit 23 determines the posture information corresponding to the tilt angle θL that is larger than the limit tilt angle θLth1. It is determined whether or not. If Yes, go to step S105; if No, go to step S106.
On the other hand, if the information acquired in step S103 is the deceleration information, it is determined whether the deceleration information corresponds to the absolute value of the deceleration Dec that is larger than the absolute value of the limit deceleration Dec_th1. do. If Yes, go to step S105; if No, go to step S106.

(Priority determination step)
In step S105, the priority determination unit 24 determines whether the priority level Prio_Lv of the event information evaluated in step S102 is smaller than the limit priority level Prio_L1, that is, as information to be notified to the rider from the limit priority level Prio_L1. Determine if the priority is low. If Yes, go to step S107, and if No, go to step S106.

(control step)
The control unit 25 causes the information transmission device to output the event information in step S106, and does not cause the information transmission device to output the event information in step S107.

<Effects of the information management system>
Effects of the information management system according to the first embodiment will be described.
The processing unit 20 includes an acquisition unit 21 for acquiring event information to be notified to the rider, a priority evaluation unit 22 for evaluating the priority of transmission of the event information to the rider, and a running state detection device provided in the motorcycle 100. Based on the driving state information corresponding to the output of 11, control the driving load state determination unit 23 that determines whether the rider is in a driving load state and the output of the event information acquired by the acquisition unit to the information transmission device When the driving load state is determined by the driving load state determination unit 23 while the motorcycle 100 is running, the control unit 25 outputs the event information to the information transmission device. , is changed according to the transmission priority evaluated by the priority evaluation unit 22 . Therefore, in a driving load state in which a considerable driving load is imposed on the rider, such as when the rider is traveling on a curve or during sudden braking, the event information transmitted from the information transmission device to the rider can be appropriately selected. Driving safety can be improved.

Preferably, the control unit 25 stops outputting the event information to the information transmission device according to the priority evaluated by the priority evaluation unit 22 . Therefore, improved rider safety is ensured.

Embodiment 2.
An information management system according to Embodiment 2 will be described below.
Note that the information management system according to the second embodiment differs from the information management system according to the first embodiment only in the operation flow of the processing unit 20 . Descriptions that overlap or are similar to those of the information management system according to the first embodiment are appropriately simplified or omitted.

<Operation of information management system>
The operation of the information management system according to Embodiment 2 will be described.
FIG. 5 is a diagram showing an operational flow of a processing unit in an information management system according to Embodiment 2 of the present invention.

The processing unit 20 executes the operation flow shown in FIG. 5 while the motorcycle 100 is running. Since steps S201-S203 and S205-S207 are the same as those in the first embodiment, description thereof will be omitted.

(Operating load state determination step)
In step S204, the driving load state determination unit 23 compares the driving state information acquired in step S203 with a threshold to determine whether or not the rider is in a driving load state.

Specifically, in step S204, if the information acquired in step S203 is the posture information, the driving load state determination unit 23 determines the posture information corresponding to the tilt angle θL that is larger than the limit tilt angle θLth1. It is determined whether or not. If Yes, go to step S205; if No, go to step S206.
On the other hand, in step S204, the control unit 25 determines that the deceleration information (absolute value of deceleration) of the motorcycle acquired in step S203 corresponds to deceleration Dec that is larger than the absolute value of limit deceleration Dec_th1. It is determined whether or not it is deceleration information. If Yes, go to step S205; if No, go to step S206.

(Priority determination step)
In step S205, the priority determination unit 24 determines whether the priority level Prio_Lv of the event information evaluated in step S202 is smaller than the limit priority level Prio_L1. is low in transmission priority. If Yes, go to step S207; if No, go to step S206.

(control step)
In step S206, the control unit 25 causes the information transmission device to output the event information. On the other hand, in step S207, the control unit 25 performs control to stop the output of the event information to the information transmission device, and then repeats the operation flow from step S204. That is, even after the driving load state is determined in step S204 and the output of the event information to the information transmission device is stopped, if the driving load state is canceled after that, the control unit 25 outputs the event information to the information transmission device. Also, since Prio_L1 is variable depending on θL, even after the operating load state is determined in step S204, if the priority level evaluated in step S205 is higher than Prio_L1, step Proceeding to S206, the control unit 25 causes the information transmission device to output the event information.

<Effects of the information management system>
Effects of the information management system according to the second embodiment will be described.
According to Embodiment 2, when the driving load state determination unit 23 determines that the driving load state has been canceled, the control unit 25 cancels the stoppage of the output of the event information to the information transmission device. Further, when the priority becomes equal to or lower than the limit priority after it is determined that the driver is in the driver's load state, the control unit 25 cancels the stop of the output of the event information to the information transmission device. Therefore, it is possible to immediately notify the driver of the information that should be notified to the rider after the driver's driving load state is released while improving the safety of the rider.

An information management system according to Embodiment 3 will be described below.
The information management system according to Embodiment 3 differs from the information management systems according to Embodiments 1 and 2 only in step S307, so only that point will be described.

In Embodiments 1 and 2, in steps S107 and S207, the control unit 25 executes control not to output the event information to the information transmission device, but in Embodiment 3, in step S307, the control unit 25 , to output the event information to the information transmission device at a lower output than the output in step S306. Specifically, when the information transmission device is a display that can be visually recognized by the rider, in step S307, the control unit outputs a display with a lower luminance than the display output of the event information in step S306.
Also, if the information transmission device is an audio device that can be recognized by the rider's sense of hearing, in step S307 the control unit outputs a volume lower than the volume of the event information in step S306.

<Effects of the information management system>
Effects of the information management system according to the third embodiment will be described.
When the priority of the event information evaluated by the evaluation unit is lower than a predetermined priority level, the control unit outputs an output lower than the output when the priority of the event information is higher than the predetermined priority level. Let
Therefore, while ensuring the safety of the rider, it is possible to transmit necessary information to the rider without affecting the rider's driving.

Although Embodiments 1 to 3 have been described above, the present invention is not limited to the description of each embodiment. For example, only part of each embodiment may be implemented, or all or part of each embodiment may be combined. Further, all or part of each step of the operation flow may be executed in a different order. good too.
