  Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 is a conceptual diagram of a system configuration in an embodiment of a notification system 1 (hereinafter, system) according to the present invention. The system 1 includes a bicycle vehicle 2 (bicycle) and an electronic key 3 (key, portable device).

  The bicycle 2 is an electrically assisted bicycle in the example of FIG. 1 and includes a communication control unit 20, a charge ECU 21, a battery 22, a motor 23, a pedal 24, wheels 25, a brake lever stroke sensor 26, a stand as a configuration related to the present invention. A position sensor 27, a vehicle speed sensor 28, and a power meter 29 are provided.

  The communication control unit 20 is a part that controls communication on the bicycle 2 side according to the present invention, and includes a communication unit 202, a control ECU 203, and a memory 204. A slot unit 200 is disposed adjacent to the communication control unit 20, and the slot unit 200 includes a sensor 201. The communication unit 202 includes a transmission unit and a reception unit, and executes signal communication between the bicycle 2 and the key 3.

  The communication between the bicycle 2 and the key 3 in the system 1 includes both wireless communication and wired communication, and the communication unit 202 includes both a wireless communication unit and a wired communication unit. Further, it is assumed that transmission to the bicycle 2 and the key 3 and transmission from the key 3 to the bicycle 2 are performed, and the communication unit 202 includes both a transmission unit and a reception unit. The control ECU 203 controls communication (wireless communication, wired communication, transmission and reception) in the communication unit 202.

  The control ECU 203 has a structure similar to that of an ordinary computer, and includes a CPU for executing various calculations and commands and a RAM as a work area of the CPU. The memory 204 stores data and programs necessary for various information processing in the control ECU 203. Note that the control ECU 203 also has a timekeeping function (timer).

  The charging ECU 21 is an ECU that controls charging of the battery 22. The charge ECU 21 also has a function of detecting the remaining amount of the battery 22. The battery 22 supplies power to the motor 23 for traveling the bicycle 2 and also supplies power for communication in the communication unit 202. In the electrically assisted bicycle 2, the motor 23 supplies driving force to the wheels 25 as well as driving force supplied by the user by stroking the pedal 24. Controls such as in what circumstances power from the motor 23 is supplied to the wheels 25 and how to adjust the ratio of power from the pedal 24 and power from the motor 23 are controlled by the conventional electrically assisted bicycle 2. Same as above.

  The slot portion 200 has a shape to which the key 3 can be attached (detachable), and attachment or detachment is detected by the sensor 201. The sensor 201 may be a known contact sensor. In the basic embodiment of the system 1, the key 3 is attached to the slot part 200 when traveling.

  The brake lever stroke sensor 26 detects the stroke amount of the brake lever (or rope) of the bicycle 2. The stand position sensor 27 detects the raising and lowering operations of the bicycle 2 stand. The vehicle speed sensor 28 detects the vehicle speed of the bicycle 2 by, for example, detecting the rotation of an encoder mounted on the wheel 25 of the bicycle 2. The power meter 29 measures the power in traveling of the bicycle 2 by a known structure or principle. In the example of FIG. 1, the bicycle 2 is an electrically assisted bicycle, but the present invention is not limited to this and may be a normal bicycle without the motor 23.

  Next, the key 3 is an electronic key whose main functions are locking (locking) and unlocking (unlocking) the bicycle 2 by wireless communication, and a function related to the present invention is added to the function. The key 3 mainly includes a CPU 30, a memory 31, a communication unit 32, an operation unit 33, a display 34, a speaker 35, and a sensor 36.

  The CPU 30 controls various equipment of the key 3. The memory 31 includes a RAM as a work area for information processing in the CPU 30 and a nonvolatile storage unit that stores data, programs, and the like necessary for information processing in the CPU 30. The communication unit 32 performs communication with the communication unit 202 of the bicycle 2. Similar to the communication unit 202, the communication unit 32 includes a transmission unit and a reception unit in each of the wireless communication unit and the wired communication unit. The operation unit 33 includes, for example, operation buttons and the like, and is a part that receives an operation on the user's key 3.

  The display 34 and the speaker 35 are parts added to the conventional electronic key 3 for the notification process performed in the present invention. The display 34 includes, for example, a liquid crystal display and displays various kinds of information (characters, numbers, pictures, symbols, etc.) as images. The speaker 35 outputs sound (or sound) for notification to the user. The sensor 36 has a structure such as a contact sensor and detects whether the key 3 is attached to or detached from the slot portion 200.

  The key 3 has a function for unlocking and locking the bicycle 2. Specifically, for example, the operation unit 33 of the key 3 is provided with a lock button and an unlock button, and the ID unique to the key 3 is stored in the memory 31, and when the user operates the lock button, the ID is received from the communication unit 32. If the lock command signal is transmitted and received by the communication unit 202 and the control ECU 203 authenticates that the ID in the received signal is the ID of the regular key 3 of the bicycle 2, the bicycle 2 is provided. The locking mechanism is locked. Similarly, when the user operates the unlock button in a state where the bicycle 2 is locked, an unlock command signal including an ID is transmitted from the communication unit 32, and is received by the communication unit 202. If the control ECU 203 authenticates that the inside ID is the ID of the regular key 3 of the bicycle 2, the lock mechanism provided in the bicycle 2 is unlocked.

  In the present invention, various information is transmitted from the bicycle 2 to the key 3 under the above-described configuration, and the contents are notified by the display 34 or the speaker 35 on the key 3 side. The information (data) to be transmitted is, for example, information related to past traveling of the bicycle 2 or information regarding whether or not various equipment of the bicycle 2 is in a state suitable for traveling.

  More specifically, the former, that is, information on past travel of the bicycle 2 includes travel distance, travel time, power consumption, calorie consumption, remaining battery power, and the like. The travel distance, travel time, power consumption, and calorie consumption may be those values in the previous travel (according to one travel from stand up to stand down) or the integrated value of past travel. For example, the travel distance may be an integrated value of travel distance per unit time calculated from the detection value of the vehicle speed sensor 28. For example, the running time may be measured by a timer provided in the control ECU 203 for the elapsed time from stand up to stand down detected by the stand position sensor 27.

  The used power is the amount of power used by the battery 22 and may be detected by the charging ECU 21. The calorie consumption may be detected by the power meter 29. The battery remaining amount may be detected by the charging ECU 21 with the remaining amount of electric power stored in the battery 22. The latter, that is, information relating to whether or not the various equipment of the bicycle 2 is in a state suitable for traveling is, for example, the remaining amount of the battery 22, whether or not the replacement time of the battery 22 has come, and whether or not the tire replacement time has come. Or whether it is time to repair the brakes. These will be described later. In the following description, unless otherwise specified, the predetermined data (data transmitted from the bicycle 2 and data received by the key 3) is various data as described above.

  Examples of processing procedures in the bicycle 2 and key 3 according to the present invention are shown in FIG. First, FIG. 2 is an example of a processing procedure for sending predetermined data from the bicycle 2 at the timing of lowering (or raising) the stand of the bicycle 2. The processing procedure of FIG. 2 (and FIGS. 3 to 7 and FIGS. 9 to 11 described later) may be programmed in advance and stored in the memory 204 and automatically called by the control ECU 203 and executed.

  In the processing procedure of FIG. 2, first in step S <b> 10, the control ECU 203 determines whether or not a signal (stand down signal) that detects that the stand has been lowered has been acquired from the stand position sensor 27. When the stand lowering signal is acquired (S10: YES), the process proceeds to S20. When the stand lowering signal is not acquired (S10: NO), S10 is repeated to wait for acquisition of the stand lowering signal.

  Alternatively, in S <b> 10, it is determined whether or not a signal (stand raising signal) for detecting that the stand has been raised is acquired from the stand position sensor 27. If a stand-up signal is acquired (S10: YES), the process proceeds to S20. If not acquired (S10: NO), S10 is repeated to wait for acquisition of a stand-up signal.

  After proceeding to S20, the control ECU 203 determines whether or not there is a change in the predetermined data transmitted from the bicycle 2 to the key 3 from the data content in the previous data transmission. Here, as described above, the predetermined data is, for example, information on past travel of the bicycle 2 or information regarding whether or not various equipment of the bicycle 2 is in a state suitable for travel. Since the predetermined data includes numerical data as exemplified above, if those numerical values have changed (above a predetermined threshold value) from the previous data transmission (S20: YES), the process proceeds to S30, and the data (predetermined) If there is no change (greater than or equal to the threshold value) (S20: NO), the process returns to S10 and the above procedure is repeated. If there is any change in the numerical value with the threshold value set to zero, S30 may be affirmative (YES). Alternatively, even when the predetermined data does not include numerical data, if there is a change, S30 may be determined as an affirmative decision (YES).

  After proceeding to S30, the control ECU 203 transmits predetermined data through the communication unit 202. In this data transmission, the control ECU 203 may perform switching so as to perform wired communication when the key 3 is attached to the slot portion 200 and wireless communication when the key 3 is detached from the slot portion 200. The above is the processing procedure of FIG. With this processing procedure, data is transmitted from the bicycle 2 to the key 3 at the timing when the user raises or lowers the stand, so that the user does not need to perform an extra operation. In addition, since the transmission timing is limited, the power required for communication can be saved.

  FIG. 3 is an example of a processing procedure for sending predetermined data from the bicycle 2 when the user performs a predetermined operation on the bicycle 2 while the vehicle is stopped. As an example of the predetermined operation, an operation of grasping the brake lever is used in the example of FIG.

  In the processing procedure of FIG. 3, first, in step S <b> 12, the control ECU 203 determines whether or not the bicycle 2 stand is being lowered. This determination may be made based on whether or not a stand lowering signal from the stand position sensor 27 has been received. If the stand is in the state of being lowered (S12: YES), the process proceeds to S14, and if it is not lowered (S12: NO), S12 is repeated to wait for it to be lowered.

  After proceeding to S14, the control ECU 203 determines whether or not the brake lever stroke sensor 26 has detected an operation of gripping the brake lever (grip operation). If a grip operation is detected (S14: YES), the process proceeds to S16. If a grip operation is not detected (S14: NO), the process returns to S12 and the above procedure is repeated.

  After proceeding to S16, the control ECU 203 determines whether or not a predetermined time has elapsed since the previous grip grip detection. If the predetermined time has elapsed (S16: YES), the process proceeds to S20. If the predetermined time has not elapsed (S16: NO), the process returns to S12 and the above procedure is repeated. In subsequent S20 and S30, the same processing as the processing of the same sign in FIG. 2 is executed. The above is the processing procedure of FIG. With this processing procedure, data is transmitted if the user performs a grip operation when he / she wants various bicycle data when the vehicle is stopped.

  FIG. 4 is an example of a processing procedure on the key 3 side. The processing procedure of FIG. 4 (and FIG. 12 to be described later) may be programmed and stored in the memory 31, and the CPU 30 may automatically call and execute it.

  In the processing procedure of FIG. 4, first, in S <b> 100, the CPU 30 determines whether data has been received by the communication unit 32. This data is, for example, the data transmitted in S30. Data received by the communication unit 32 may be stored in the memory 31. If data has been received (S100: YES), the process proceeds to S110. If data has not been received (S100: NO), S100 is repeated to wait for reception.

  After proceeding to S110, the CPU 30 notifies the contents included in the received data. Specifically, the notification process may be a display on the display 34, a sound (voice) output from the speaker 35, or a combination thereof. In S110, the received data is not immediately notified, but the information received and stored in the memory 31 may be notified at a predetermined timing.

  The notification contents in S110 are contents corresponding to the received data, but in that case, the relationship between the received data and the notification contents may be a form in which the received data is notified as it is, and the received data is subjected to some conversion. The form which alert | reports may be sufficient. As an example of the former, there is an example in which the numerical value of the remaining battery level is transmitted in the process of FIG. 2 and the numerical value transmitted in the process of FIG. As an example of the latter, the numerical value of the remaining battery level is transmitted in the process of FIG. 2, and when the remaining capacity transmitted in the process of FIG. 4 is small, it is converted into a sentence such as “the remaining battery level is low”. There is an example to notify. The above is the processing procedure of FIG. The data confirmed to be received in S100 of FIG. 4 is not limited to the data transmitted in S30, but may be data transmitted from the bicycle 2 described later.

  The processing procedure of FIG. 5 is a procedure on the side of the bicycle 2 in a process of counting the number of times of charging the battery 22 and informing the user that the battery should be replaced when it reaches a predetermined value or more.

  In the process of FIG. 5, the user first charges the battery 22 in S200. In response to this, the control ECU 203 determines in S210 whether or not the number of times of charging is a predetermined value or more. The information on the number of times of charging may be transmitted to the control ECU 203 after being counted by the charging ECU 21, for example. When the number of times of charging is equal to or greater than a predetermined value (S210: YES), the process proceeds to S220, and when it is less than the predetermined value (S210: NO), the process of FIG.

  After proceeding to S220, the control ECU 203 transmits information indicating that the number of times of charging is equal to or greater than a predetermined value or information for prompting replacement of the battery 22 from the communication unit 32. The key 3 that has received this transmission content makes a notification prompting the user to replace the battery 22 by the process of FIG. The above is the processing procedure of FIG. With this processing procedure, the user can know with the electronic key that the bicycle battery has reached the replacement time.

  The processing procedure of FIG. 6 is a procedure on the side of the bicycle 2 in a process of notifying the tire replacement when the travel distance becomes a predetermined value or more. The process in FIG. 6 may be executed at predetermined time intervals, for example.

  In the process of FIG. 6, first in step S300, the control ECU 203 determines whether or not the travel distance has become a predetermined value or more. Information on the travel distance may be calculated by the control ECU 203 using rotation detection by the vehicle speed sensor 28. When the travel distance is equal to or greater than the predetermined value (S300: YES), the process proceeds to S310, and when the travel distance is less than the predetermined value (S300: NO), the process of FIG.

  After proceeding to S310, the control ECU 203 transmits information indicating that the travel distance has become equal to or greater than a predetermined value or information prompting tire replacement from the communication unit 202. The key 3 which has received this transmission content performs a notification for urging tire replacement by the process of FIG. The above is the processing procedure of FIG. With this processing procedure, the user can know with the electronic key that the bicycle tire has reached the replacement time.

  The processing procedure of FIG. 7 is a procedure on the side of the bicycle 2 in a process of notifying the user that the brake is repaired when the brake rope is extended to the extent that it needs to be replaced (when bent). The processing in FIG. 7 may be executed during traveling, for example.

  In the process of FIG. 7, first in step S400, the control ECU 203 determines whether or not an operation of the brake lever has been detected. Information on operation of the brake lever may be acquired from the brake lever stroke sensor 26. When the operation of the brake lever is detected (S400: YES), the process proceeds to S410, and when the operation of the brake lever is not detected (S400: NO), S400 is repeated to wait for the operation.

  After proceeding to S410, the control ECU 203 determines whether or not the increasing speed of the brake lever stroke amount is equal to or greater than a predetermined threshold value. The threshold here is a threshold that can be used to determine whether or not the brake is sudden. As for the information on the increasing speed of the brake lever stroke amount, the control ECU 203 obtains the detected value of the brake lever stroke sensor 26 and calculates the increasing speed (that is, the value obtained by dividing the stroke amount increment by the time increment). Good. An example of this increase rate is illustrated in FIG.

  If the increasing speed of the stroke amount is not equal to or greater than the predetermined threshold (S410: NO), the process proceeds to S420. If the increasing speed of the stroke amount is equal to or greater than the predetermined threshold (S410: YES), the process returns to S400 and the above procedure is repeated. Thus, the case of sudden braking is excluded from the case of proceeding to S420.

  After proceeding to S420, the control ECU 203 accumulates data on the stroke rate increasing speed. As a result, data on the increasing speed of the brake stroke amount when the brake is not sudden is collected. The control ECU 203 calculates an average value of the increasing speeds of the collected brake stroke amounts.

  In step S430, the control ECU 203 determines whether the calculated average value of the increasing speed of the brake stroke amount is equal to or greater than a predetermined threshold value. Here, the threshold value is a threshold value for determining whether or not the brake rope has been extended to an extent that requires replacement. If the average value is equal to or greater than the predetermined threshold (S430: YES), the process proceeds to S430. If the average value is less than the predetermined threshold (S430: NO), the process returns to S400 and the above procedure is repeated.

  Accordingly, when the process proceeds to S440, since the average value of the increase speed of the brake stroke amount is large rather than the sudden brake, it is considered that the brake rope is extended to an extent that requires replacement. Accordingly, in step S440, the control EC 203 transmits information indicating that the brake is to be repaired (brake rope replacement). The key 3 that has received this transmission content issues a notification that prompts repair of the brake by the processing of FIG. The above is the processing procedure of FIG. This processing procedure allows the user to know with the electronic key that the bicycle brake has reached the time for repair and replacement. The key 3 that has received the information transmitted by the processes of FIGS. 5, 6, and 7 may continue notification until replacement or repair is performed.

  The processing procedure of FIG. 9 is a procedure on the side of the bicycle 2 in the process of notifying the charging rate information every moment during charging. In this process, the charge rate data is transmitted only when the key (the user who owns the key) exists around the bicycle 2. For this purpose, a process of transmitting a polling signal from the bicycle to the key 3 and confirming the presence of the key 3 is included as in the so-called smart key system.

  In the process of FIG. 9, first, in step S500, the control ECU 203 determines whether charging of the battery 22 has been started. Information on whether or not charging is performed may be acquired from the charging ECU 21. When charging is started (S500: YES), the process proceeds to S510, and when charging is not started (S500: NO), S500 is repeated.

  After proceeding to S510, the control ECU 203 transmits a polling signal from the communication unit 202. The polling signal is a wireless signal for obtaining a response from the peripheral key 3, and is, for example, a signal in the LF (long wave) band.

  In step S520, the control ECU 203 determines whether the communication unit 202 has received a signal returned from the key 3 in response to the polling signal (response signal, for example, an RF signal in the UHF band). If a response signal has been received (S520: YES), the process proceeds to S530, and if no response signal has been received (S520: NO), the process returns to S510 and the above procedure is repeated. Note that an ID specific to the key 3 may be included in the response signal, and an authentication process may be performed to determine whether the ID received in S520 is the ID of the regular key of the bicycle 2. Naturally, the case where a response signal is received and the ID of the authorized key is authenticated is an affirmative determination (YES), and the other case is a negative determination (NO).

  After proceeding to S530, the control ECU 203 transmits charge amount data from the communication unit 202. What is necessary is just to acquire the information of charge amount from charge ECU21 every moment.

  In step S540, the control ECU 203 determines whether charging has ended. When the charging is finished (S540: YES), the process of FIG. 9 is finished. When the charging is not finished (S540: NO), the process returns to S510 and the above procedure is repeated. The key 3 that has received the data transmitted in S530 notifies the charge amount every moment through the processing of FIG. Thus, the charging amount is notified to the key 3 from time to time during the charging period and during the period in which the key 3 (or the user who owns it) is near the bicycle. The above is the processing procedure of FIG. With this processing procedure, the user can know the charge amount information momentarily using the key 3 during charging. Note that the processing of S510 and S520 may be performed prior to any data transmission from the bicycle in the present invention.

  The processing procedure of FIG. 10 is a procedure on the side of the bicycle 2 in a process of notifying predetermined data every time during traveling.

  In the process of FIG. 10, first in step S600, the control ECU 203 determines whether or not the bicycle 2 has started running. This determination may be made based on the detection value of the vehicle speed sensor 28. When the travel is started (S600: YES), the process proceeds to S610, and when the travel is not started (S600: NO), S600 is repeated to wait for the travel start.

  After proceeding to S610, the control ECU 203 determines whether a predetermined time has elapsed since the previous data transmission. If the predetermined time has elapsed (S610: YES), the process proceeds to S620. If the predetermined time has not yet elapsed (S610: NO), S610 is repeated to wait for the predetermined time to elapse.

  Alternatively, in S610, it may be determined whether or not the current vehicle speed of the bicycle 2 is equal to or higher than a predetermined speed. If the speed is equal to or higher than the predetermined speed (S610: YES), the process proceeds to S620. If the speed is lower than the predetermined speed (S610: NO), S610 is repeated to wait for the speed to be higher than the predetermined speed.

  After proceeding to S620, the control ECU 203 transmits predetermined data from the communication unit 202. In the case where the key 3 is attached to the slot portion 200 during traveling as described above, this transmission may be performed by wired communication.

  In step S630, the control ECU 203 determines whether the travel has ended. When the travel is finished (S630: YES), the processing of FIG. 10 is terminated, and when the travel is still performed (S630: NO), the process returns to S610 and the above procedure is repeated. The key 3 that has received the data transmitted in S620 notifies the received predetermined data by the process of FIG. In that case, the display on the display 34 is always displayed, and the display content may be updated every time it is received (or at a predetermined speed or more). The above is the processing procedure of FIG.

  With this processing procedure, the user can acquire various information using the electronic key while traveling (not only when the vehicle is stopped). At this time, the data transmission timing is limited to a case where a predetermined time has elapsed since the previous transmission or a case where the transmission speed is equal to or higher than a predetermined speed, so that power by communication is saved. In addition, when the transmission timing is limited when the speed is higher than the predetermined speed, the data is not transmitted when the numerical value does not fluctuate when the predetermined data to be transmitted includes, for example, mileage data. Can send.

  The processing procedure of FIG. 11 is a procedure on the bicycle 2 side in a process of notifying predetermined data at the timing when the key 3 is attached to the slot part 200.

  In the processing procedure of FIG. 11, first, in step S <b> 700, the control ECU 203 determines whether or not the key 3 is attached to the slot part 200. The detection of the attachment of the key 3 may be performed by the sensor 201. If the key 3 is attached (S700: YES), the process proceeds to S710. If the key 3 is not attached (S700: NO), S700 is repeated to wait for the key to be attached.

  After proceeding to S710, the control ECU 203 transmits predetermined data from the communication unit 202. Since the key 3 is mounted in the slot portion 200, this transmission may be performed by wired communication. The above is the processing procedure of FIG. With this processing procedure, the user can acquire various types of information with the electronic key when the key is attached (before starting running). Moreover, since the transmission timing is limited, power can be saved.

  The processing procedure of FIG. 12 is a procedure on the key 3 side in a process of notifying predetermined data at the timing when the key 3 is attached to the slot part 200.

  In the processing procedure of FIG. 11, first, in S800, the CPU 30 determines whether or not the slot unit 200 is attached. This attachment detection may be performed by the sensor 36. If it is mounted in the slot unit 200 (S800: YES), the process proceeds to S810. If it is not mounted in the slot unit 200 (S800: NO), S800 is repeated to wait for the key mounting.

  After proceeding to S810, the CPU 30 activates the display 34 or the speaker 35. In S820, the CPU 30 determines whether or not data (for example, transmitted in S620 or S710) is received by the communication unit 32. If received (S820: YES), the process proceeds to S830, and if not received (S820: NO), S820 is repeated to wait for reception.

  After proceeding to S830, the CPU 30 notifies the received data content via the display 34 or the speaker 35. As in S110 described above, the notification content in S830 is determined according to the received data, and the relationship between the received data and the notification content may be a form in which the received data is notified as it is, and some conversion is performed on the received data. The form which gives and alert | reports may be sufficient. The above is the processing procedure of FIG. By this processing procedure, the user can acquire various types of information with the electronic key during traveling or when the key is attached (before starting traveling).

  The above-described embodiments may be arbitrarily changed within the scope of the gist of the claims. For example, in the configuration of FIG. 1, the bicycle 2 is an electrically assisted bicycle. However, the present invention is not limited to this and can be applied to bicycles in general. In the above description, when the key 3 is mounted in the slot, the communication between the key 3 and the communication unit 202 is wired communication, but may be wireless communication.
