Description

  The present invention provides a vehicle control system for performing optimal control for a bicycle user.

  In recent years, the use of bicycles has been increasing with the emphasis on environmental issues and personal health. In recent bicycles, the number of electric bicycles that assist when climbing a slope is increasing, and the price is increasing. Under such circumstances, the number of bicycle thefts is also increasing. Therefore, it is common for a user to lock the bicycle and unlock it. In this case, the user locks the bicycle with the key attached to the front wheel or the rear wheel of the bicycle and carries the locked key. And when riding a bicycle, the key you have points to the keyhole and unlocks.

Here, in the conventional unlocking method, the key is locked by pushing the lock claw attached to the front wheel or rear wheel of the bicycle, and the key is pulled out. When unlocking, the carried key is inserted into the key. It will be unlocked by removing the lock claw, but it will be forced to unlock with an unreasonable posture, and there is a high possibility that the hands and arms will come into contact with the wheel and others, and the clothes will be dirty. Is done. On the other hand, a system that can be unlocked and locked remotely has been studied. This is a mechanism in which a user has a key capable of wireless communication and can unlock and lock a bicycle remotely by simply pressing a button attached to the key.

(Embodiment 1)
FIG. 1 shows a system configuration diagram of Embodiment 1 of the present invention. In FIG. 1, 1 is a bicycle. Reference numeral 2 denotes a travel detection unit. 3 is an unlocking part. Reference numeral 4 denotes an input unit. In FIG. 1, (a) shows a case where the bicycle 1 is stopped, and (b) shows a case where the bicycle 1 is running.

  In FIG. 1A, the operation will be described with reference to the flowchart of FIG. When the user stops the bicycle 1 and stands still and is not locked yet (unlocking), the user then locks the bicycle 1. In this case, the user operates the input unit 4 of the bicycle 1 to lock the bicycle 1. Specifically, for example, the input unit 4 is a push button type switch, and the user performs locking by pressing the switch (S31 in FIG. 3). When the user performs the locking operation in this manner, the input unit 4 tries to perform the locking operation by receiving the input signal in the state of “unlocking” (S32 in FIG. 3). Here, the input unit 4 makes an inquiry to the travel detection unit 2. The inquiry content is whether or not the bicycle 1 is currently running.

  In FIG. 1, the travel detection unit 2 is attached to a stand of a bicycle 1. The travel detection unit 2 detects whether or not the bicycle 1 stand is standing. This is because when the stand is standing, the bicycle 1 is stopped, that is, not running, and when the stand is not standing, the bicycle 1 can be regarded as being running.

  When receiving an inquiry from the input unit 4, the traveling detection unit 2 determines whether the vehicle is traveling or stopped depending on whether the stand is currently standing or not, and sends the result to the input unit 4. In the case of FIG. 1A, the fact that the vehicle is stopped is sent to the input unit 4. When the input unit 4 obtains information indicating that the vehicle is stopped from the travel detection unit 2 (S33 in FIG. 3), the input unit 4 determines that the locking may be performed, and issues a locking instruction to the unlocking unit 3. When receiving the locking instruction from the input unit 4, the unlocking / locking unit 3 locks the bicycle 1 (S34 in FIG. 3).

  In FIG. 1, the unlocking portion 3 is attached to the rear wheel of the bicycle 1, and the rear wheel of the bicycle 1 is locked by some method for locking. Thus, the bicycle 1 transits from “unlocking” to “locking”. In this way, the user confirms that the bicycle 1 is locked and leaves the place.

  Next, a case where the user returns to his / her bicycle 1 and tries to ride the bicycle 1 will be described. When the user wants to ride the bicycle 1 from now on, the switch of the input unit 4 is pushed as before (S31 in FIG. 3). Here, the input unit 4 tries to perform the unlocking operation by receiving the input signal in the currently “locking” state (S32 in FIG. 3). Here, the input unit 4 makes an inquiry to the travel detection unit 2. The inquiry content is whether or not the bicycle 1 is currently running.

When receiving an inquiry from the input unit 4, the traveling detection unit 2 determines whether the vehicle is traveling or stopped depending on whether the stand is currently standing or not, and sends the result to the input unit 4. In the case of FIG. 1A, the fact that the vehicle is stopped is sent to the input unit 4. When the input unit 4 obtains information indicating that the vehicle is stopped from the travel detection unit 2 (S33 in FIG. 3), the input unit 4 determines that the unlocking may be performed, and issues an unlocking instruction to the unlocking unit 3. When receiving the unlocking instruction from the input unit 4, the unlocking / locking unit 3 unlocks the bicycle 1 (S34 in FIG. 3). As a result, the bicycle 1 transits from “locking” to “unlocking”. In this way, the user confirms that the bicycle 1 is unlocked, removes the stand, and rides the bicycle.

  Next, a case where the user erroneously presses the lock button while traveling will be described with reference to the flowcharts of FIG. 1B and FIG. The input unit 4 receives the input signal in a state of “unlocking” at present (S31 in FIG. 3), and tries to perform the locking operation (S32 in FIG. 3). Here, the input unit 4 makes an inquiry to the travel detection unit 2. The inquiry content is whether or not the bicycle 1 is currently running.

  When receiving an inquiry from the input unit 4, the traveling detection unit 2 determines whether the vehicle is traveling or stopped depending on whether the stand is currently standing or not, and sends the result to the input unit 4. In the case of FIG. 1B, the fact that the vehicle is running is sent to the input unit 4. When the input unit 4 obtains information indicating that the vehicle is traveling from the traveling detection unit 2, the input unit 4 determines that the locking is not allowed (S33 in FIG. 3), and does not give the locking / unlocking unit 3 a locking instruction. As a result, the bicycle 1 is not locked. As a result, even if the user accidentally presses the locking button while traveling, the bicycle 1 is not locked, so the rear wheels are not locked in FIG. 1 and a serious accident can be prevented.

  As described above, the user can easily lock and unlock the bicycle with one touch, and can prevent a serious accident resulting from locking due to an erroneous operation.

  In the above embodiment, the information exchange between the input unit 4 and the travel detection unit 2 and between the input unit 4 and the unlocking unit 3 may be performed by connecting them with a wire or by connecting them wirelessly. May be.

  In the above embodiment, the input unit 4 has the current state of the bicycle 1, that is, the state of “unlocking” or “locking”, and there is an input to the input unit 4 accordingly. In addition, it is configured to determine whether the input is an unlocking request or a locking request. However, the input unit 4 is provided with an unlocking switch and a locking switch, and it is determined whether the unlocking request is made depending on which switch is operated. The input unit 4 may have the state of “unlocking” or “locking”, and may be included in the unlocking / unlocking unit 3.

  Furthermore, in the above embodiment, the input unit 4 inquires of the traveling detection unit 2 about the traveling state, acquires the result, and determines whether or not to issue an instruction to the unlocking unit 3. A method may be used in which the part 2 is always or when the running state is changed, the fact is sent to the input unit 4 or the unlocking unit 3 and the input unit 4 or the unlocking unit 3 holds the state of whether or not the vehicle is running. .

(Embodiment 2)
FIG. 2 shows a system configuration diagram of Embodiment 2 of the present invention. The description of the same role as in FIG. 1 is omitted. In FIG. 2, 5 is a wireless key.

  2 will be described with reference to the flowchart of FIG. A user of the bicycle 1 always carries the wireless key 5. That is, the user of the bicycle 1 always carries the wireless key 5 in a bag, a pocket or the like, and the wireless key 5 can be regarded as proof that the owner of the bicycle 1 is the owner.

  Here, as in the first embodiment, a case where the user stops the bicycle 1 is considered. In FIG. 2, when the user stops the bicycle 1 and stands still and is not locked (unlocking), the user then locks the bicycle 1.

  In this case, the user operates the input unit 4 of the bicycle 1 to lock the bicycle 1. Specifically, for example, the input unit 4 is a push button type switch, and the user performs locking by pressing the switch (S41 in FIG. 4). When the user performs the locking operation in this manner, the input unit 4 attempts to perform the locking operation by receiving the input signal in the currently “unlocking” state (S42 in FIG. 4). Here, the input unit 4 makes an inquiry to the travel detection unit 2. The inquiry content is whether or not the bicycle 1 is currently running.

  When receiving an inquiry from the input unit 4, the traveling detection unit 2 determines whether the vehicle is traveling or stopped depending on whether the stand is currently standing or not, and sends the result to the input unit 4. In the case of FIG. 2, the fact that it is stopped is sent to the input unit 4. When the input unit 4 obtains information indicating that the vehicle is stopped from the traveling detection unit 2 (S43 in FIG. 4), the input unit 4 then performs wireless communication with the wireless key 5.

  Here, when the user performs locking while the bicycle 1 is unlocked, the user should be near the bicycle 1 because the user presses the switch of the input unit 4 as described above. Therefore, the wireless key 5 possessed by the user should be near the bicycle 1.

  Therefore, when the input unit 4 of the bicycle 1 tries to perform wireless communication with the wireless key 5, the wireless key 5 should exist within a range where radio waves can reach sufficiently. Communication succeeds. Here, when the wireless communication with the wireless key 5 is successful, the input unit 4 recognizes that the user himself / herself has pressed the switch of the input unit 4. That is, personal authentication is established (S44 in FIG. 4).

  When the wireless communication with the wireless key 5 is successful and the personal authentication is established, the input unit 4 determines that the locking may be performed, and issues a locking instruction to the unlocking unit 3. When receiving the locking instruction from the input unit 4, the unlocking / locking unit 3 locks the bicycle 1 (S45 in FIG. 4). Thus, the bicycle 1 transits from “unlocking” to “locking”. In this way, the user confirms that the bicycle 1 is locked and leaves the place.

  On the other hand, the same applies to the case where the user returns to his / her bicycle 1 and tries to ride the bicycle 1 from now on. That is, when the user wants to ride the bicycle 1 from now on, the switch of the input unit 4 is pushed as before (S41 in FIG. 4). Here, the input unit 4 attempts to perform the unlocking operation by receiving the input signal in the currently “locking” state (S42 in FIG. 4). Here, the input unit 4 makes an inquiry to the travel detection unit 2. The inquiry content is whether or not the bicycle 1 is currently running.

  When receiving an inquiry from the input unit 4, the traveling detection unit 2 determines whether the vehicle is traveling or stopped depending on whether the stand is currently standing or not, and sends the result to the input unit 4. In the case of FIG. 2, the fact that it is stopped is sent to the input unit 4. When the input unit 4 obtains information indicating that the vehicle is stopped from the traveling detection unit 2 (S43 in FIG. 4), the input unit 4 then performs wireless communication with the wireless key 5. When the wireless communication with the wireless key 5 is successful, the input unit 4 recognizes that the user himself / herself has pressed the switch of the input unit 4. That is, personal authentication is established (S44 in FIG. 4).

When the wireless communication with the wireless key 5 is successful and the personal authentication is established, the input unit 4 determines that the unlocking may be performed and issues an unlocking instruction to the unlocking unit 3. When receiving the unlocking instruction from the input unit 4, the unlocking unit 3 unlocks the bicycle 1 (S45 in FIG. 4). As a result, the bicycle 1 transits from “locking” to “unlocking”. In this way, the user confirms that the bicycle 1 is unlocked, removes the stand, and rides the bicycle.

  Next, consider a case where a malicious person tries to steal the bicycle 1. When the bicycle 1 is “locked” and a malicious person presses the switch of the input unit 4 (S41 in FIG. 4), the travel detection unit 2 determines that the bicycle 1 is stopped (S43 in FIG. 4). However, the wireless communication between the input unit 4 and the wireless key 5 is not successful. This is because the user of the bicycle 1 is not in the vicinity, so that the person cannot be authenticated (S44 in FIG. 4). Therefore, the unlocking part 3 does not operate, and as a result, the bicycle 1 is not unlocked.

  As described above, by constructing a mechanism for identity authentication using the wireless key 5, only the owner of the bicycle 1 can realize the unlocking that can be performed only while the bicycle 1 is stopped, and the safety of the unlocking is achieved. In addition, security can be improved from the viewpoint of theft prevention. Even when the bicycle 1 is parked and locked, the user authentication with the wireless key 5 can be performed. By doing so, it is possible to prevent others from locking for mischief.

  Further, in the present embodiment, the wireless key 5 carried by the owner of the bicycle 1 is not provided with a switch such as a button, and the unlocking of the bicycle 1 is performed by the input unit attached to the bicycle 1. This can be realized by operating the switch 4. In other words, the bicycle 1 is not unlocked by a switch attached to the wireless key 5. This means that when the bicycle 1 is unlocked, the user does not have to search for the wireless key 5 from a bag, a pocket or the like. That is, since the owner of the bicycle 1 can carry the wireless key 5 anywhere, the bicycle 1 can be easily unlocked. This means that there is no need to search for a key or to insert or remove the key, and the convenience for the user can be greatly improved.

  As described above, in the present embodiment, the method has been described in which the input unit 4 grasps the state of the travel detection unit 2 and then performs the authentication with the wireless key 5, but when the user switch is pressed on the input unit 4. After the user authentication with the wireless key 5 first, if the user authentication is successful, the traveling detection unit 2 may be checked for the traveling state.

  In addition, as described in the first embodiment, the information exchange between the input unit 4 and the travel detection unit 2 and between the input unit 4 and the unlocking unit 3 may be performed by connecting each other by wire or wirelessly. You may connect.

  Further, when the input unit 4 has the current state of the bicycle 1, that is, the state of “unlocking” or “locking”, and there is an input to the input unit 4 accordingly, the input is unlocked Although it was set as the structure which judges whether it is a request | requirement or a lock | rock request | requirement, the input part 4 is provided with the unlocking switch and the locking switch, and the structure which judges whether it is a unlocking request | requirement or a locking request | requirement by which switch was operated. Alternatively, the input unit 4 may not be in the “unlocking” or “locking” state, but may be included in the unlocking unit 3.

  Further, the input unit 4 inquires of the traveling detection unit 2 about the traveling state, and combines the result with the result of the personal authentication with the wireless key 5 to determine whether or not to issue an instruction to the unlocking unit 3. However, when the traveling detection unit 2 is constantly or when the traveling state is changed, the fact is sent to the input unit 4 or the unlocking unit 3 to determine whether the input unit 4 or the unlocking unit 3 is traveling. The method of holding may be used. Further, the person authentication with the wireless key 5 may be performed not by the input unit 4 but by the travel detection unit 2 or the unlocking unit 3.

By the way, the personal authentication is performed wirelessly between the input unit 4 and the wireless key 5. Specifically, the ID of the bicycle 1 and the ID of the wireless key 5 are wirelessly communicated, and the personal authentication is performed using the ID verification. The method of performing is considered.

  For example, the ID of the wireless key 5 is stored in advance in the bicycle 1 in some way, and the ID of the wireless key 5 mounted on the radio wave transmitted from the wireless key 5 matches the ID stored by itself. In such a case, the identity of the bicycle 1 is regarded as successful, and conversely, the ID of the bicycle 1 is previously stored in the wireless key 5 in some way. There is also a method in which an ID is installed and the bicycle 1 authenticates itself by comparing the ID received at the time of reception with its own ID.

  The same can be realized on the wireless key 5 side, and the wireless key 5 collates the ID of the bicycle 1 mounted on the transmission radio wave transmitted from the bicycle 1 to the wireless key 5 or the ID of the wireless key 5 at the time of reception. You can also. By doing so, the reliability of wireless communication between the bicycle 1 and the wireless key 5 is increased, and the identity authentication accuracy is improved.

  In addition, the bicycle 1 can measure the received electric field strength when receiving the radio wave from the wireless key 5, and can determine whether or not the personal authentication is successful based on the result. More specifically, the bicycle 1 stores a predetermined reception field strength threshold value. The reception field strength is measured when radio waves are received from the wireless key 5 and the result is stored in advance. This is a method in which the identity authentication is regarded as a success when the number exceeds. This is a concept of performing distance detection based on the received electric field strength. If the received electric field strength is low, the distance between the bicycle 1 and the wireless key 5 is increased. Conversely, if the received electric field strength is high, the bicycle 1 and This is a determination that the distance from the wireless key 5 is short. As a result, it can be determined whether the owner of the bicycle 1 is in the vicinity of the bicycle 1, and the authenticity of the personal authentication is improved. For example, a malicious person tries to steal the bicycle 1. In addition, it is possible to prevent the owner from unlocking at a delicate timing when the owner leaves the bicycle 1. Here, the received electric field strength may be determined by a single measurement, or may be determined by measuring a plurality of times and using a median value or an average value. By measuring a plurality of times, it is possible to eliminate the influence of fluctuations in the received electric field strength due to fading and improve the determination accuracy.

  Furthermore, in wireless communication between the bicycle 1 and the wireless key 5, communication data can be encrypted. For example, by providing a common key (encryption key) for both the bicycle 1 and the wireless key 5 and performing encryption and decryption of wireless communication using the encryption key, the confidentiality of the data is increased. This makes it difficult for others to manipulate the data with malicious intent. As a result, the accuracy of personal authentication can be greatly increased.

  Note that the radio wave used for the wireless communication between the bicycle 1 and the wireless key 5 can be performed using a specific low-power radio such as a 400 MHz band. In addition, a communication medium such as weak radio wave, infrared ray, wireless LAN, wireless tag, Bluetooth (registered trademark), or Zigbee (registered trademark) may be used.

  As described above, in the first embodiment and the second embodiment, the travel detection unit 2 has been described using the determination whether the bicycle stand is standing or not. However, the travel detection unit 2 detects whether the vehicle is traveling by another method. May be. For example, a method may be used in which a sensor is provided in the wheel portion of the bicycle 1 to detect whether or not the wheel is rotating.

(Embodiment 3)
FIG. 5 shows a system outline diagram of the third embodiment. In FIG. 5, it is assumed that the bicycle 1 is equipped with a wireless device, and the bicycle is shared and used by a plurality of users. Each individual owns the wireless key 5. The wireless key 5 can be automatically unlocked by using wireless communication when each person gets on and off the bicycle without manually unlocking the bicycle. This is the so-called bicycle version of the smart entry function.

  A plurality of (four people in FIG. 5) users have different ages and physiques. And hobbies and tastes are different, and each wants to ride a shared bicycle in a style that suits their tastes. Here, it is assumed that the saddle height automatic adjustment function is added to the bicycle 1.

  Next, a case where a certain user gets on the bicycle 1 is considered. The user approaches his bicycle 1 with his wireless key 5. Then, wireless communication is performed between the bicycle 1 and the wireless key 5 possessed by the user, and the bicycle 1 recognizes that the user is approaching (trying to get on). Then, the bicycle 1 operates the saddle height automatic adjustment function to increase the saddle height (the optimum saddle height according to the user's physique).

  On the other hand, when another user tries to get on the bicycle 1 in the same manner, the saddle height is lowered (the optimum saddle height is adjusted to the physique of the other user). Thus, by automatically adjusting the optimum saddle height according to the rider, user convenience is greatly improved.

  FIG. 6 shows an unlocking unit and a wireless key internal block mounted on the bicycle 1 according to the third embodiment.

  The unlocking unit mounted on the bicycle 1 includes a wireless communication unit 601 for performing wireless communication with the external wireless key 5, a traveling detection unit 2 that determines whether or not the bicycle 1 is traveling, and a saddle 604 of the bicycle 1. The height information of the saddle 604 is transmitted from the external wireless key 5 and is received by the wireless communication unit 601 in a state where the bicycle 1 is not traveling by the driving means 603 for adjusting the height and the traveling detection unit 2. In addition, it is determined that the distance between the wireless key 5 and the bicycle 1 has reached a predetermined distance or electric field strength level, and the driving means 603 is turned on according to the height information of the saddle 604 included in the message. It comprises control means 602 for controlling.

  The wireless communication unit 601 uses a short-range radio wave, UWB (Ultra Wide Band), weak, specific low-power radio, or the like used in RFID (Radio Frequency Identification) via an antenna. The transmission and reception of a signal including an identification code set in a pair with the key unit 120 by pairing processing is controlled based on a predetermined protocol, and an amplifier circuit, a modulation circuit, a demodulation circuit, a phase synchronization circuit, an amplitude limiting circuit, and a filter circuit , An oscillation circuit, a phase comparison circuit, a counting circuit, an analog / digital conversion circuit, a digital conversion circuit, a mixer, a level detection circuit, and the like.

  The traveling detection means 2 is a method for determining the traveling state based on the position information of the vehicle fixing means attached to the rear wheel of the bicycle 1 based on whether the bicycle 1 is fixed to the ground, or an element that generates magnetism on the wheels of the bicycle 1. The reed switch is attached to the fork that fixes the wheel, the speed is detected by rotating the wheel, the running is detected, the power generator is attached to the axle, and the mechanism that can detect the voltage when the wheel rotates, It is configured to determine whether or not the vehicle is running.

  The driving unit 603 includes a motor for controlling the height of the saddle 604 and a position detecting unit for detecting the height of the saddle 604.

  The control unit 602 controls the driving unit 603 based on information for communicating with a predetermined protocol and height information of the saddle 604 transmitted from the external wireless key 5 via the wireless communication unit 602. In order to generate data for processing and to process the information of the travel detection means 2, it is constituted by an arithmetic unit such as a microcomputer constituted by a semiconductor or the like.

  On the other hand, since the wireless key 5 communicates with the wireless communication unit 601 in the bicycle 1 according to a predetermined protocol, the key wireless communication means 650, the unique ID of the wireless key 5, and the owner of the wireless key 5 are 1 is composed of storage means 651 for storing height information of the saddle 604 when boarding 1.

  The key wireless communication means 650 transmits short-range radio waves used in RFID (Radio Frequency Identification), UWB (Ultra Wide Band), weak, specific low power radio, etc. via an antenna. Controls transmission / reception of a signal including an identification code set in a pair with the key unit 120 using pairing processing based on a predetermined protocol, and an amplifier circuit, a modulation circuit, a demodulation circuit, a phase synchronization circuit, an amplitude limiting circuit, a filter Circuits such as a circuit, an oscillation circuit, a phase comparison circuit, a counting circuit, an analog / digital conversion circuit, a digital conversion circuit, a mixer, and a level detection circuit are included.

  The storage unit 651 includes a semiconductor memory for storing a unique ID of the wireless key 5, owner information of the wireless key 5, and height information of the saddle 604 of the bicycle 1.

  Subsequently, a flow for adjusting the height of the saddle 604 of the bicycle 1 according to the third embodiment will be described with reference to FIG.

  First, the traveling state of the bicycle 1 is detected by the traveling detection unit 2, and if the state in which the bicycle 1 is not traveling is detected, the process proceeds to the next step, and if it is in the traveling state, this step remains (S701). Next, the wireless communication unit 601 is activated at a predetermined cycle, and carrier sense (CS confirmation) is performed in order to receive a message transmitted from an external wireless key. Here, the predetermined period may be varied, for example, when the period is 4 seconds or when the first 24 hours is a period of 4 seconds and after that, the period is 8 seconds.

  Here, when the carrier sense cannot be confirmed, the process returns to the previous step S701. If radio waves can be detected, the process proceeds to the next step (S702). Subsequently, authentication communication is performed with the wireless key 5. Here, the authentication communication is established only with the bicycle 1 and the wireless key 5 preliminarily assembled. At the same time, the authentication communication is established when the electric field strength level is detected from the message transmitted from the wireless key 5 and the electric field strength equal to or higher than a predetermined level is detected. As a result, the authentication communication cannot be established unless the positional relationship between the bicycle 1 and the wireless key 5 is within a predetermined distance or area. If the authentication communication is not established, the process returns to S701. If established, the process proceeds to the next step (S703). The message received in step S703 includes user information and height information of the saddle 604 in addition to the ID of the wireless key 5, and the wireless communication unit 601 performs demodulation (S704). Subsequently, the control unit 602 generates a control amount for controlling the saddle 604 by the driving unit 603 according to the height information of the saddle 604 received in the previous step S704 (S705). The drive unit 603 adjusts the height of the saddle 604 according to the control amount generated in S705 (S706).

  From the above, if individual saddle height information is stored in the plurality of wireless keys 5 for the bicycle 1 as shown in FIG. 5, the optimum saddle height for each user is set before riding the bicycle 1. Therefore, user convenience is improved.

(Embodiment 4)
In the fourth embodiment, as in the third embodiment, it is assumed that the bicycle 1 is equipped with a wireless device as shown in FIG. 5, and the bicycle is shared and used by a plurality of users. At that time, each user owns the wireless key 5. The specification of the bicycle 1 can be individually set for each user. In the fourth embodiment, the electric bicycle has a mechanism for changing the assist amount for each user.

  FIG. 8 shows an internal block diagram of the unlocking unit and the wireless key mounted on the bicycle 1 according to the fourth embodiment. A description of a configuration having the same function as that of the third embodiment will be omitted, and the block in the bicycle 1 and the wireless key 5 different from FIG. 6 will be described.

  In FIG. 8, the speed detection means 608 of the bicycle 1 detects the speed from the number of rotations of wheels and axles. The control unit 602 calculates control data for controlling the auxiliary drive unit 606 according to the speed amount detected by the speed detection unit 608 based on information stored in the vehicle storage unit 609 in advance. The auxiliary drive unit 606 controls the pedal axle 607 based on the control data calculated by the control unit 602.

  The speed detection means 608 includes a detection circuit using a hall element or the like on the axle, generates a pulse from the position information of the axle, counts the pulse and converts it to a speed, or turns the reed switch on / off with a magnetic element. The number of times is counted per unit time, or the period is calculated and converted into a speed.

  The auxiliary drive means 606 is power for applying a rotational force directly or indirectly to the pedal axle to which the pedal is connected based on the control data calculated by the control means 602, and is composed of, for example, a DC motor. ing.

  The vehicle storage means 609 is composed of a semiconductor element such as a flash memory. Further, here, speed information detected by the speed detection means 608 as input, a transfer function whose output becomes the control amount of the auxiliary drive means 606, coefficients of the transfer function, and the like are stored. The expression method is expressed by table data, functions, or the like. A part of this transfer function is included as individual specification setting information in a message transmitted from the wireless key 5. The personal specification setting information transmitted from the wireless key 5 reflects the individual specification together with the transfer function and the like previously stored in the vehicle storage unit 609 in the control unit 602 after being received and demodulated by the wireless communication unit 601. Generate a transfer function.

  FIG. 9A shows a table for converting the speed detected by the speed detection means 608 stored in the vehicle storage means 609 in the bicycle 1 into a control amount applied to the auxiliary drive means 606. FIG. 9B shows individual specification setting information stored in the storage unit 651 in the wireless key 5.

  In FIG. 9A, the transfer function is expressed in a table format, and auxiliary control amounts C0 to C4 applied to the auxiliary control means 606 are stored for the speeds 0 to 4 detected by the speed detection means 608. . Here, C0 to C4 are in an initial state, and general numerical values are inputted. On the other hand, the individual specification setting information shown in FIG. 9B describes the auxiliary control amount for the speed customized by the user who owns the wireless key 5. Here, eigenvalues of 0, 2, 4, 2, 1 are stored for the auxiliary control amounts C0 to C4. The individual specification setting information stored in FIG. 9B is modulated from the key wireless communication means 650 of the wireless key 5 and transmitted to the bicycle 1. The transmitted information is received and demodulated by the wireless communication unit 601 in the bicycle 1 and updated by the control unit 602 according to the data format read from the vehicle storage unit 609.

The information stored in the storage means 651 of the wireless key 5 includes user's individual information, wireless key identification ID, wireless key 5 owner information, bicycle 1 body information, etc., as well as user preferences and health. Information set individually according to the state and physical strength may be stored, and a plurality of pieces of information may be taken into consideration, and a coefficient of a transfer function that outputs a control amount of the auxiliary driving unit 606 in the bicycle 1 may be generated. As a result, when the user holding the wireless key 5 approaches the predetermined distance or area on the bicycle 1 that is stopped, the communication is performed and the transmission stored in the storage means of the wireless key 5 is performed. By including the coefficient of the function in the message and communicating with the bicycle 1, it is possible to customize the control of the auxiliary driving means 606 of the electric bicycle so as to make the specification suitable for the user.

  Next, regarding the transfer function stored in the vehicle storage means 609 in the bicycle 1, a sequence for reflecting the coefficient of the transfer function unique to the user stored in the storage means 611 of the wireless key 5 will be described. FIG. 10 shows a processing flow at that time.

  First, the traveling state of the bicycle 1 is detected by the traveling detection unit 2, and if the state in which the bicycle 1 is not traveling is detected, the process proceeds to the next step. If the traveling state is in the traveling state, the process stays at this step (S1001). Next, the wireless communication unit 601 is activated at a predetermined time, and carrier sense (CS confirmation) is performed in order to receive a message transmitted from an external wireless key.

  Here, when carrier sense cannot be confirmed, it returns to previous step S1001. If radio waves can be detected, the process proceeds to the next step (S1002). Subsequently, authentication communication is performed with the wireless key 5. Here, the authentication communication is established only with the bicycle 1 and the wireless key 5 preliminarily assembled. At the same time, the authentication communication is established when the electric field strength level is detected from the message transmitted from the wireless key 5 and the electric field strength equal to or higher than a predetermined level is detected. As a result, the authentication communication cannot be established unless the positional relationship between the bicycle 1 and the wireless key 5 is within a predetermined distance or area.

  If authentication communication is not established, the process returns to S1001, and if established, the process proceeds to the next step (S1003). The electronic message received in step S1003 includes the transfer function coefficient for calculating the control amount of the auxiliary driving means 606 from the user information and the speed detected by the speed detecting means 608 in addition to the ID of the wireless key 5. The radio communication unit 601 performs demodulation (S1004). Subsequently, the transfer function and the coefficient stored in the vehicle storage unit 609 are read out to the control unit 602 (S1005), and if it is necessary to update by comparing with the coefficient of the transfer function received in step S1004, the coefficient is rewritten. If it is equivalent to the stored information, the data is retained (S1006). The data rewritten in the previous step S1006 is stored again in the vehicle storage means 609.

  From the above, if the coefficients of the individual transfer functions are stored in the plurality of wireless keys 5 for the bicycle 1 as shown in FIG. 5, the control amount of the auxiliary drive for the speed can be varied for each user. Bicycles with specifications that suit the user can be realized. Here, the transfer function related to the control amount of the auxiliary drive means with respect to the speed is controlled. However, a transfer function that determines the control amount of the auxiliary drive means based on travel time, pedaling force, rotation speed, body weight, amount of exercise, etc. A transfer function that calculates a control amount using a plurality of amounts may be used. Therefore, the information in the message transmitted from the wireless key may be a coefficient of these transfer functions, the transfer function itself, or information directly including the above information.

FIG. 11 shows an internal block diagram of the bicycle 1 and the wireless key 5 in the fifth embodiment. Here, the description regarding the configuration having the same function as in the third and fourth embodiments is omitted, and the block and the wireless key 5 in the bicycle 1 different from those in FIGS. 6 and 8 will be described.

The pedal effort detection means 610 in the bicycle 1 detects the force applied to the axle connected to the pedal of the bicycle 1. In addition to the pedal effort information acquired by the pedal effort detector 610, the controller 602 generates a message including speed information obtained from the speed detector 608, travel information data such as the distance traveled by the user, and time. Then, the wireless communication unit 601 performs modulation in accordance with a predetermined protocol and transmits the modulated signal to the wireless key 5.

  The pedaling force detection means 610 calculates the force applied to the axle connected to the pedal of the bicycle 1 by converting the stress into a voltage using a piezo element or the like.

  On the other hand, the key calculation means 652 in the wireless key 5 generates individual specification setting information for the bicycle 1 to be transmitted to the bicycle 1 via the key wireless communication unit 601. The individual specification setting information relates to a transfer function calculated in the control amount of the auxiliary driving means 606 from the information output from the speed detecting means 608 or the like in the bicycle 1 or its coefficient. The key calculation means 652 updates the individual specification setting information stored in the storage means 651 with the travel information data transmitted from the bicycle 1.

  Next, a method for updating the individual specification setting information by the key calculation means 652 will be described with reference to FIGS. FIG. 12 shows a graph for calculating the multiplication factor of the coefficient of the transfer function using the pedal effort information among the travel information data transmitted from the bicycle 1. According to FIG. 12, when the pedal effort information is 5, a numerical value of 0.4 is obtained. Next, FIG. 13 shows that the individual specification setting information is updated by multiplying the value of the individual specification setting information C0 to C4 used up to the previous time by a magnification of 0.4. The updated individual specification setting information is stored in the storage unit 651 and is also transmitted to the bicycle 1.

  Next, a sequence for updating the individual specification setting information from the travel information data between the bicycle 1 and the wireless key 5 will be described with reference to FIG. Authentication communication is periodically performed between the bicycle 1 and the wireless key 5 using a challenge and response method. The wireless key 5 transmits a search message at a predetermined cycle (S1401). When the bicycle 1 receives the electronic message of S1401, the electronic message including the identification ID is transmitted to the wireless key 5 in advance (S1402). When the wireless key 5 matches the identification ID when the bicycle 1 is preliminarily associated with the bicycle 1, a signal for communicating that the identification ID matches is transmitted to the bicycle 1 (S1403). When the bicycle 1 receives the electronic message transmitted in S1403, it transmits a challenge request to the wireless key 5 (S1404). The wireless key 5 that has received the challenge request returns a challenge signal generated by generating a random number to the bicycle 1 (S1405), and the bicycle 1 that has received the challenge signal performs a response generated by performing encryption processing on this signal. A signal is transmitted to the wireless key 5 (S1406). Subsequently, the wireless key 5 that has received the response signal confirms whether the decrypted response signal and the challenge signal match, and if they match, determines that the authentication has succeeded and transmits that fact to the bicycle 1 (S1407). . When the authentication is established, the travel information data is transmitted from the bicycle 1 to the wireless key 5 (S1408). In the wireless key 5, the individual specification setting data stored in the storage unit 651 is updated based on the travel information data, stored again in the storage unit 651, and transmitted to the bicycle 1 via the key wireless communication unit 650. (S1409). In the bicycle 1, the individual specification setting data transmitted from the wireless key 5 is received by the wireless communication unit 601, and the control unit 602 updates the information stored in the vehicle storage unit 609 in advance with the individual use setting data.

  On the other hand, if the authentication fails, the wireless key 5 shifts to a standby mode to a mode for transmitting a search message. Even if the transmission / reception of the above signal is interrupted during authentication using the challenge-and-response method between the bicycle 1 and the wireless key 5, the bicycle 1 shifts to the standby mode and starts transmitting the identification ID. become.

From the above, if the coefficients of the individual transfer functions are stored in the plurality of wireless keys 5 for the bicycle 1, the control amount of the auxiliary drive with respect to the speed can be varied for each user, and the user's Depending on the usage situation, it is possible to acquire travel time, travel distance, and pedaling force information and update the control amount using the information. As a result, detailed customization is possible depending on the state of the user's body, preferences, and the like. Here, the transfer function related to the control amount of the auxiliary drive means with respect to the speed is controlled. However, a transfer function that determines the control amount of the auxiliary drive means based on travel time, pedaling force, rotation speed, body weight, exercise amount, etc. may be used. A transfer function that calculates a control amount using a plurality of amounts may be used. Therefore, the information in the message transmitted from the wireless key may be a coefficient of these transfer functions, the transfer function itself, or information directly including the above information.

Here, a description of a configuration having the same function as in the third, fourth, and fifth embodiments will be omitted, and only the wireless key 5 that is different from FIGS. 6, 8, and 11 will be described.

  The exercise amount detecting means 653 in the wireless key 5 detects the amount of exercise of the user when the wireless key 5 is held by the user and not on the bicycle 1. The amount of exercise referred to here detects the distance that the user has moved on foot, the calorie consumption at that time, the number of steps, and the like.

  Further, the key calculation means 652 calculates the accumulated exercise amount in a state where the user has not appeared on the exercise bicycle 1 within a predetermined time based on the output of the exercise amount detection means 653. In addition, the individual specification setting information stored in the storage unit 651 is updated based on the accumulated exercise amount.

  The momentum detecting means 653 is composed of any one of an acceleration sensor, an angle sensor, a pressure sensor, a gravity sensor, a direction sensor, and the like, and when the user holding the wireless key 5 exercises, level fluctuation occurs in the sensor output. . This level fluctuation is input to the key calculation means 652, and the calculation means 652 captures the number of fluctuations of the sensor output and calculates the accumulated motion amount.

  Based on the above, it is possible to grasp how much the user holding the wireless key 5 is exercising while not riding the bicycle 1, and creating individual specification setting information based on that information To do. Furthermore, a transfer function for calculating the control amount of the auxiliary drive means of the bicycle 1 with respect to the output of the speed detection means can be generated based on the individual specification setting information. For example, if the user determines that the exercise is insufficient, the control amount is calculated. If it can be reduced or it can be determined that the user is exercising sufficiently, a large amount of control can be set. That is, the user's unique information can be finely varied according to the user's condition, and fine customization can be achieved.

FIG. 16 shows an internal block diagram of the bicycle 1 and the wireless key 5 in the seventh embodiment. Here, description of elements having functions similar to those of the third, fourth, fifth, and sixth embodiments will be omitted, and only the wireless key 5 that is different from FIGS. 6, 8, 11, and 15 will be described.

  The time output means 654 in the wireless device 5 includes a crystal resonator, a ceramic resonator, an oscillation circuit, or an oscillation circuit using a crystal or a ceramic element, and outputs the time. The storage means stores individual specification setting information and a function for outputting a magnification with respect to time. When transmitting the individual specification setting information to the bicycle 1, the key calculation means 652 performs correction and transmission in accordance with the transmission time.

The correction of the individual specification setting information will be described with reference to FIG. The storage unit 651 stores a table in which individual specification setting information (auxiliary control amount 0, 2, 4, 2, 1 for addresses C0 to C4) and a magnification with respect to time are described. The key calculation means 652 first reads the individual specification setting information, and then reads the time from the time output means 654. In FIG. 17, the time of 18:45 is read out. Next, the key calculation unit 652 searches the magnification table stored in the storage unit 651 for the magnification corresponding to the time of 18:45. Here, the time 18:45 falls within the range of 17:00 to 24:00, and the magnification 2 is read. Subsequently, the magnification 2 is multiplied by all the addresses C0 to C4 of the individual specification setting information that has already been read, and the correction is completed.

  From the above, the user holding the wireless key 5 can set the individual specifications at the time when he / she wants to ride the bicycle 1 and can ride the bicycle. Thereby, a user's action pattern can be estimated and a specification can be changed automatically. For example, in the morning, you ’re likely to be in a hurry and have a lot of auxiliary control, so that you ’ll have plenty of time in the afternoon to drive your bike as easily as possible, thinking about maintaining your health rather than driving fast, The amount of auxiliary control is small, and in the evening, tiredness of the day has accumulated, so it is possible to determine detailed specifications such as determining the amount of auxiliary control so that the bicycle can be driven easily.
