As needed or desired, the first wireless communicator circuit WC1 and the second wireless communicator circuit WC2 may be configured to use a protocol other than Bluetooth (registered trademark).

[0137] As seen in Figure 6 and Figure 7 for example, the direction information INF11 may include an angle of arrival AG1. The angle of arrival AG1 is defined based on the relative positions between the first wireless communicator circuit WC1 and the second wireless communicator circuit WC2 in the human-powered vehicle 2. The electronic controller circuit EC1 is configured to obtain the angle of arrival AG1.

[0146] For example, the first antenna circuit WC13 includes the first antenna WC15. The second antenna circuit WC23 includes at least two second antennas WC25. That is, the first wireless communicator circuit WC1 includes the first antenna WC15. The second wireless communicator circuit WC2 includes at least two second antennas WC25. The at least two second antennas WC25 are equally spaced apart.

[0147] The departure angle AG2 is defined based on the positional relationship between the first antenna WC15 and the at least two second antennas WC25 in the second wireless communicator circuit WC2 of the human-powered vehicle 2.

[0148] The total number of the at least two second antennas WC25 is greater than or equal to three. However, depending on need or desire, the total number of the at least two second antennas WC25 may be equal to two. The total number of the at least two second antennas WC25 is not limited to the illustrated embodiments.

The electronic controller circuit EC1 is configured to obtain the phase difference (ψ) and the wavelength (λ) based on the direction finding signal SG2 received by the first antenna. The at least two second antennas WC25 are arranged at a distance (d) defined between two adjacent antennas among the at least two second antennas WC25. Therefore, the electronic controller circuit EC1 is configured to calculate the departure angle AG2 based on the following formula (2). The electronic controller circuit EC1 is configured to store the departure angle AG2 as the information INF1 in the memory EC12.

[0171] As seen in Figure 2 the control system 10 of the human-powered vehicle 2 includes a sensor 12. The sensor 12 is configured to be connected to at least one of the first wireless communication circuit WC1, the second wireless communication circuit WC2, and the electronic controller circuit EC1. The sensor 12 is configured to be electrically connected to at least one of the first wireless communication circuit WC1, the second wireless communication circuit WC2, and the electronic controller circuit EC1.

[0173] The first wireless communication circuit WC1 is provided on the fixed part of the human-powered vehicle 2. The sensor 12 is provided on the fixed part of the human-powered vehicle 2. For example, the electrical device ED1 is mounted on the vehicle body 8. The circuit board EC13 is fixed to the base member ED11.

The sensor 12 is coupled to the vehicle body 8 via the circuit board EC13 and the base member ED11.

[0174] The following will refer toFigure 10 and Figure 11 Describe the first control executed by control system 10 based on information INF1.

[0175] As seen in Figure 10 The electronic controller circuit EC1 performs pairing between the first wireless communicator circuit WC1 and the second wireless communicator circuit WC2 (step ST11). The electronic controller circuit EC1 obtains information INF1 (step ST2). For example, the second electronic controller circuit EC2 controls the second wireless communicator circuit WC2 to wirelessly transmit a direction finding signal SG2 at a specific period (step ST21). The first wireless communicator circuit WC1 wirelessly receives the direction finding signal SG2 (step ST22). The electronic controller circuit EC1 calculates information INF1 based on the direction finding signal SG2 (step ST23). Specifically, the electronic controller circuit EC1 calculates the angle of arrival AG1 or the angle of departure AG2 based on the direction finding signal SG2 (step ST23). Therefore, the electronic controller circuit EC1 obtains the angle of arrival AG1 or the angle of departure AG2 as information INF1 or direction information INF11. The electronic controller circuit EC1 calibrates the default position obtained from information INF1 (step ST12). The electronic controller circuit EC1 initializes the system of the electrical device ED1 (step ST13).

[0176] As seen in Figure 11 The electronic controller circuit EC1 obtains information INF1 (step ST3). For example, the second electronic controller circuit EC2 controls the second wireless communicator circuit WC2 to wirelessly transmit a direction finding signal SG2 at a specific period (step ST31). The first wireless communicator circuit WC1 wirelessly receives the direction finding signal SG2 (step ST32). The electronic controller circuit EC1 calculates information INF1 based on the direction finding signal SG2 (step ST33). Specifically, the electronic controller circuit EC1 calculates the angle of arrival AG1 or the angle of departure AG2 based on the direction finding signal SG2 (step ST33). Therefore, the electronic controller circuit EC1 obtains the angle of arrival AG1 or the angle of departure AG2 as information INF1 or direction information INF11.

[0177] The electronic controller circuit EC1 generates at least one control signal CS1 based on information INF1 (step ST4). For example, the electronic controller circuit EC1 compares information INF1 with a first threshold TA1 (step ST41). When the value of information INF1 is greater than the first threshold TA1, the electronic controller circuit EC1 generates a first control signal CS11 (steps ST41 and ST42). Specifically, the electronic controller circuit EC1 generates the first control signal CS11 when the angle of arrival AG1 or the angle of departure AG2 is greater than the first threshold TA1 (steps ST41 and ST42).

[0178] When the value of information INF1 is equal to or less than the first threshold TA1, the electronic controller circuit EC1 compares the information INF1 with the first threshold TA1 and the second threshold TA2 (steps ST41 and ST43). When the value of information INF1 is greater than the second threshold TA2, the electronic controller circuit EC1 generates a second control signal CS12 (steps ST43 and ST44). Specifically, the electronic controller circuit EC1 generates the second control signal CS12 when the arrival angle AG1 or the departure angle AG2 is greater than the second threshold TA2 (steps ST43 and ST44).

[0179] When the value of information INF1 is equal to or less than the second threshold TA2, the electronic controller circuit EC1 generates a third control signal CS13 (steps ST43 and ST45). Specifically, the electronic controller circuit EC1 generates the third control signal CS13 when the arrival angle AG1 or the departure angle AG2 is equal to or less than the second threshold TA2 (steps ST43 and ST45).

[0180] The additional electronic controller circuit EC3 changes the state of the additional electrical device ED3 based on at least one control signal CS1 (step ST5). For example, the additional electronic controller circuit EC3 changes the state of the additional electrical device ED3 to a first state based on the first control signal CS11 (step ST51). The additional electronic controller circuit EC3 changes the state of the additional electrical device ED3 to a second state based on the second control signal CS12 (step ST52). The additional electronic controller circuit EC3 changes the state of the additional electrical device ED3 to a third state based on the third control signal CS13 (step ST53). Therefore, it is possible to change the state of the additional electrical device ED3 according to the positional relationship between the first wireless communicator circuit WC1 and the second wireless communicator circuit WC2. After changing the state of the additional electrical device ED3, the process returns to step ST3.

[0181] When the second electrical device ED2 includes an adjustable seat tube AS and the additional electrical device ED3 includes a suspension SS, the suspension SS changes its state based on the movement of the adjustable seat tube AS.

[0182] As in Figure 12As can be seen, for example, when the angle of arrival AG1 or the angle of departure AG2 is greater than the first threshold TA1, the length of the adjustable seat tube AS is greater than the first predetermined length, indicating that the adjustable seat tube AS has a long length and the position of the saddle 8S is high. When the adjustable seat tube AS has a long length, the suspension SS changes its state to the first state in response to the first control signal CS11 (steps ST71, ST72, and ST81). That is, when the adjustable seat tube AS has a long length, the suspension SS absorbs or damps shocks or vibrations in the first state, within the first stroke, or with the first damping performance. For example, the first stroke is shorter than the second and third strokes. The second stroke is shorter than the third stroke. The first stroke can be zero. The first damping performance is lower than the second and third damping performances. The second damping performance is lower than the third damping performance. Therefore, when the adjustable seat tube AS has a long length, the suspension SS is locked and cannot absorb or damp shocks or vibrations.

[0183] When the angle of arrival AG1 or the angle of departure AG2 is less than or equal to the first threshold TA1 and greater than the second threshold TA1, the length of the adjustable seat tube AS is less than or equal to the first predetermined length and longer than the second predetermined length, indicating that the adjustable seat tube AS has an intermediate length and the position of the saddle 8S is intermediate. When the adjustable seat tube AS has an intermediate length, the suspension SS changes its state to the second state in response to the second control signal CS12 (steps ST71, ST73, ST74, and ST82). That is, when the adjustable seat tube AS has an intermediate length, the suspension SS absorbs or damps shocks or vibrations in the second state, within the second stroke, or with the second damping performance. Therefore, when the adjustable seat tube AS has an intermediate length, the suspension SS can absorb or damp shocks or vibrations in an intermediate range.

[0184] When the angle of arrival AG1 or the angle of departure AG2 is less than or equal to the second threshold TA1, the length of the adjustable seat tube AS is less than or equal to the second predetermined length, indicating that the adjustable seat tube AS has a short length and the position of the saddle 8S is low. When the adjustable seat tube AS has a short length, the suspension SS changes its state to the third state in response to the third control signal CS13 (steps ST73, ST75, and ST83). That is, when the adjustable seat tube AS has a short length, the suspension SS absorbs or damps shocks or vibrations in the third state, within the third stroke, or with the third damping performance. Therefore, when the adjustable seat tube AS has a short length, the suspension SS can absorb or damp shocks or vibrations in a wide range.

[0185] When the second electrical device ED2 includes the suspension SS and the additional electrical device ED3 includes the suspension SS, the suspension SS changes its state based on the movement of the suspension SS.

[0186] As shown in Figure 13 it, for example, when the arrival angle AG1 or the departure angle AG2 is greater than the first threshold TA1, the length of the suspension SS is greater than the first predetermined length, indicating that the suspension SS has a long length. When the suspension SS has a long length, the suspension SS changes its state to the first state in response to the first control signal CS11 (steps ST71, ST72, and ST81). That is, when the suspension SS has a long length, the suspension SS absorbs or damps shock or vibration within the first stroke or under the first damping performance in the first state. For example, the first stroke is longer than the second stroke and the third stroke. The second stroke is longer than the third stroke. The first damping performance is higher than the second damping performance and the third damping performance. The second damping performance is higher than the third damping performance. Therefore, when the suspension SS has a long length, the suspension SS can absorb or damp shock or vibration within a wide range.

[0187] When the arrival angle AG1 or the departure angle AG2 is less than or equal to the first threshold TA1 and greater than the second threshold TA1, the length of the suspension SS is shorter than or equal to the first predetermined length and longer than the second predetermined length, indicating that the suspension SS has an intermediate length and the position of the saddle 8S is intermediate. When the suspension SS has an intermediate length, the suspension SS changes its state to the second state in response to the second control signal CS12 (steps ST71, ST73, ST74, and ST82). That is, when the suspension SS has an intermediate length, the suspension SS absorbs or damps shock or vibration within the second stroke or under the second damping performance in the second state. Therefore, when the suspension SS has an intermediate length, the suspension SS can absorb or damp shock or vibration within an intermediate range.

[0188] When the arrival angle AG1 or the departure angle AG2 is less than or equal to the second threshold TA1, the length of the suspension SS is less than or equal to the second predetermined length, indicating that the suspension SS has a short length and the position of the saddle 8S is low. When the suspension SS has a short length, the suspension SS changes its state to the third state in response to the third control signal CS13 (steps ST73, ST75, and ST83). That is, when the suspension SS has a short length, the suspension SS absorbs or damps shock or vibration within the third stroke or under the third damping performance in the third state. Therefore, when the suspension SS has a short length, the suspension SS can absorb or damp shock or vibration within a narrow range.

[0189] When the second electrical device ED2 includes the operating device ST and the additional electrical device ED3 includes the braking device BD, the braking device BD changes its state based on the movement of the operating device ST. The movement of the operating device ST includes the movement of the handlebar 8H. That is, the braking device BD changes its state based on the movement of the handlebar 8H.

[0190] As seen in Figure 14 Figure 14 , for example, in the case where the arrival angle AG1 or the departure angle AG2 is greater than the first threshold TA1, the operating device ST is in the neutral position relative to the frame 8F, which indicates that the handlebar 8H is in the neutral position relative to the frame 8F about the axis of rotation. In the case where the operating device ST is in the neutral position, the braking device BD changes its state to the first state in response to the first control signal CS11 (steps ST71, ST72, ST81). That is, in the case where the operating device ST is in the neutral position, the braking device BD operates in the first state in a normal manner. Therefore, in the case where the operating device ST is in the neutral position, the braking device BD applies a braking force to the wheels 7A and / or 7B in response to the operation of the operating device ST.

[0191] In the case where the arrival angle AG1 or the departure angle AG2 is less than or equal to the first threshold TA1 and greater than the second threshold TA1, the operating device ST is in the intermediate position relative to the frame 8F, which means that the handlebar 8H is in the intermediate position relative to the frame 8F about the axis of rotation. In the case where the operating device ST is in the intermediate position, the braking device BD changes its state to the second state in response to the second control signal CS12 (steps ST71, ST73, ST74, and ST82). That is, in the case where the operating device ST is in the intermediate position, the braking device BD operates in the second state in a normal manner. Therefore, in the case where the operating device ST is in the intermediate position, the braking device BD applies a braking force to the wheels 7A and / or 7B in response to the operation of the operating device ST.

[0192] In the case where the arrival angle AG1 or the departure angle AG2 is less than or equal to the second threshold TA1, the operating device ST is in the terminal position relative to the frame 8F, which indicates that the handlebar 8H is in the terminal position relative to the frame 8F about the axis of rotation. In the case where the operating device ST is in the terminal position, the braking device BD changes its state to the third state in response to the third control signal CS13 (steps ST73, ST75, and ST83). For example, in the case where the operating device ST is in the terminal position, the braking device BD is locked and unable to apply a braking force regardless of the operation of the operating device ST in the third state.

[0193] In the case where the second electrical device ED2 includes the operating device ST and the additional electrical device ED3 includes the transmission RD, the transmission RD changes its state based on the movement of the operating device ST. The movement of the operating device ST includes the movement of the handlebar 8H. That is, the transmission RD changes its state based on the movement of the handlebar 8H.

[0194] As seen in Figure 15As can be seen, for example, when the arrival angle AG1 or the departure angle AG2 is greater than the first threshold TA1, the operating device ST is in a neutral position relative to the frame 8F, which indicates that the handlebar 8H is in a neutral position relative to the frame 8F about the axis of rotation. When the operating device ST is in the neutral position, the transmission RD changes its state to a first state in response to the first control signal CS11 (steps ST71, ST72, ST81). That is, when the operating device ST is in the neutral position, the transmission RD operates in a normal manner in the first state. Therefore, when the operating device ST is in the neutral position, the transmission RD applies a braking force to the wheels 7A and / or 7B in response to the operation of the operating device ST.

[0195] When the arrival angle AG1 or the departure angle AG2 is less than or equal to the first threshold TA1 and greater than the second threshold TA1, the operating device ST is in an intermediate position relative to the frame 8F, which means that the handlebar 8H is in an intermediate position relative to the frame 8F about the axis of rotation. When the operating device ST is in the intermediate position, the transmission RD changes its state to a second state in response to the second control signal CS12 (steps ST71, ST73, ST74 and ST82). That is, when the operating device ST is in the intermediate position, the transmission RD operates in a normal manner in the second state. Therefore, when the operating device ST is in the intermediate position, the transmission RD applies a braking force to the wheels 7A and / or 7B in response to the operation of the operating device ST.

[0196] When the arrival angle AG1 or the departure angle AG2 is less than or equal to the second threshold TA1, the operating device ST is in a terminal position relative to the frame 8F, which indicates that the handlebar 8H is in a terminal position relative to the frame 8F about the axis of rotation. When the operating device ST is in the terminal position, the transmission RD changes its state to a third state in response to the third control signal CS13 (steps ST73, ST75, ST83). For example, when the operating device ST is in the terminal position, the transmission RD downshifts regardless of the operation of the operating device ST in the third state.

[0197] When the second electrical device ED2 includes the operating device ST and the additional electrical device ED3 includes the auxiliary drive unit DU, the auxiliary drive unit DU changes its state based on the movement of the operating device ST. The movement of the operating device ST includes the movement of the handlebar 8H. That is, the auxiliary drive unit DU changes its state based on the movement of the handlebar 8H.

[0198] As in Figure 16As can be seen, for example, when the arrival angle AG1 or the departure angle AG2 is greater than the first threshold TA1, the operating device ST is in a neutral position relative to the frame 8F, which indicates that the handlebar 8H is in a neutral position relative to the frame 8F about the axis of rotation. When the operating device ST is in the neutral position, the auxiliary drive unit DU changes its state to the first state in response to the first control signal CS11 (steps ST71, ST72, ST81). That is, when the operating device ST is in the neutral position, the auxiliary drive unit DU operates in a normal manner in the first state. Therefore, when the operating device ST is in the neutral position, the auxiliary drive unit DU applies a braking force to the wheels 7A and / or 7B in response to the operation of the operating device ST.

[0199] When the arrival angle AG1 or the departure angle AG2 is less than or equal to the first threshold TA1 and greater than the second threshold TA1, the operating device ST is in an intermediate position relative to the frame 8F, which means that the handlebar 8H is in an intermediate position relative to the frame 8F about the axis of rotation. When the operating device ST is in the intermediate position, the auxiliary drive unit DU changes its state to the second state in response to the second control signal CS12 (steps ST71, ST73, ST74, ST82). That is, when the operating device ST is in the intermediate position, the auxiliary drive unit DU operates in a normal manner in the second state. Therefore, when the operating device ST is in the intermediate position, the auxiliary drive unit DU applies a braking force to the wheels 7A and / or 7B in response to the operation of the operating device ST.

[0200] When the arrival angle AG1 or the departure angle AG2 is less than or equal to the second threshold TA1, the operating device ST is in a terminal position relative to the frame 8F, which indicates that the handlebar 8H is in a terminal position relative to the frame 8F about the axis of rotation. When the operating device ST is in the terminal position, the auxiliary drive unit DU changes its state to the third state in response to the third control signal CS13 (steps ST73, ST75, ST83). For example, when the operating device ST is in the terminal position, the auxiliary drive unit DU reduces the auxiliary ratio regardless of the operation of the operating device ST.

[0201] When the electrical device ED includes an adjustable seat tube AS, the second electrical device ED2 includes a wearable device WD, and the additional electrical device ED3 includes a suspension SS, the suspension SS changes its state based on the movement of the wearable device WD relative to the adjustable seat tube AS. That is, when the wearable device WD is attached to the body of the rider (such as the rider's waist or the rider's head), the suspension SS changes its state based on the movement of the rider's body relative to the saddle 8S.

[0202] As in Figure 17As seen, for example, when the angle of arrival AG1 or the angle of departure AG2 is greater than the first threshold TA1, the distance between the wearable device WD and the adjustable seat tube AS is greater than the first predetermined distance, indicating that the rider's body has moved away from the saddle 8S. That is, the rider lifts off the saddle 8S when the wearable device WD is in a state where the distance is greater than the first predetermined distance.

[0203] When the distance between the wearable device WD and the adjustable seat tube AS is greater than the first predetermined distance, the suspension SS changes its state to the first state in response to the first control signal CS11 (steps ST71, ST72, and ST81). That is, when the distance between the wearable device WD and the adjustable seat tube AS is greater than the first predetermined distance, the suspension SS absorbs or damps shock or vibration in the first state, within the first stroke, or with the first damping performance. For example, the first stroke is shorter than the second and third strokes. The second stroke is shorter than the third stroke. The first stroke can be zero. The first damping performance is lower than the second and third damping performances. The second damping performance is lower than the third damping performance. Therefore, when the distance between the wearable device WD and the adjustable seat tube AS is greater than the first predetermined distance, the suspension SS is locked and unable to absorb or damp shock or vibration.

[0204] When the angle of arrival AG1 or the angle of departure AG2 is less than or equal to the first threshold TA1 and greater than the second threshold TA1, the length of the wearable device WD is less than or equal to the first predetermined distance and greater than the second predetermined distance, indicating that the wearable device WD is at a medium distance from the adjustable seat tube AS. When the wearable device WD is at a medium distance from the adjustable seat tube AS, the suspension SS changes its state to the second state in response to the second control signal CS12 (steps ST71, ST73, ST74, and ST82). That is, when the wearable device WD is at a medium distance from the adjustable seat tube AS, the suspension SS absorbs or dampens shock or vibration in the second state, within the second stroke, or with the second damping performance. Therefore, when the wearable device WD is at a medium distance from the adjustable seat tube AS, the suspension SS can absorb or dampen shock or vibration within a medium range.

[0205] When the angle of arrival AG1 or the angle of departure AG2 is less than or equal to the second threshold TA1, the length of the wearable device WD is less than or equal to the second predetermined distance, indicating that the wearable device WD is at a short distance from the adjustable seat tube AS. That is, in the state where the wearable device WD is at a short distance from the adjustable seat tube AS, the rider is on the saddle 8S. When the wearable device WD is at a short distance from the adjustable seat tube AS, the suspension SS changes its state to the third state in response to the third control signal CS13 (steps ST73, ST75, and ST83). That is, when the wearable device WD is at a short distance from the adjustable seat tube AS, the suspension SS absorbs or dampens shocks or vibrations in the third state, within the third stroke, or with the third damping performance. That is, when the wearable device WD is at a short distance from the adjustable seat tube AS, the suspension SS can absorb or dampen shocks or vibrations within a wide range.

[0206] The position detection system used in the control system 10 can be used together with another sensor such as a position sensor and a motion sensor.

The saddle load sensor S4 is configured to obtain the second load applied to the saddle 8S (see, for example, Figure 1 ) or the position change of the saddle 8S (see, for example, Figure 1 ) along the lateral direction of the human-powered vehicle 2 as the second saddle load. If desired, the control system 10 and / or the user can select the information obtained by the sensors.

[0211] The auxiliary power sensor S5 is configured to sense the auxiliary power of the auxiliary drive unit DU (see, for example, Figure 1 ) as the auxiliary power output. The rider motion sensor S6 is configured to sense the motion of the rider. The chain state sensor S7 is configured to sense the chain 5 (see, for example, Figure 1)'s state as the chain state.

The crank power sensor S10 is configured to obtain the crank torque applied from the user to the crank 3 (see, for example, Figure 1 ).

[0212] Each of the pressure sensor S1, the acceleration sensor S2, the handlebar load sensor S3, the saddle load sensor S4, the auxiliary power sensor S5, the rider motion sensor S6, the chain state sensor S7, the speed sensor S8, the cadence sensor S9, and the crank power sensor S10 may include a wireless communicator circuit configured to wirelessly communicate with wireless communicator circuits such as the first wireless communicator circuit WC1, the second wireless communicator circuit WC2, and the additional wireless communicator circuit WC3.

Another of the wireless communicator circuits WC1, WC2, and WC3 is configured to wirelessly receive at least one control signal CS27. The electronic controller circuits EC1, EC2, or EC3 are configured to limit the function of the device ED based on at least one control signal CS27. The device ED is configured to limit the function of the device ED based on at least one control signal CS27.

[0226] The electronic controller circuits EC1, EC2, or EC3 are configured to generate at least one control signal CS28 if the traveling speed is greater than a speed threshold for a predetermined time. One of the wireless communicator circuits WC1, WC2, and WC3 is configured to wirelessly transmit at least one control signal CS28. Another of the wireless communicator circuits WC1, WC2, and WC3 is configured to wirelessly receive at least one control signal CS28. The electronic controller circuits EC1, EC2, or EC3 are configured to limit the function of the device ED based on at least one control signal CS28. The device ED is configured to limit the function of the device ED based on at least one control signal CS28.

[0227] As seen in Figure 19 in the Figure 18 illustrated variant, at least one control signal CS2 at least includes: a first limiting control signal CS2A for limiting the function of the device ED to a first operating state; a second limiting control signal CS2B for setting the device ED to a second operating state different from the first operating state; and a third limiting control signal CS2C for setting the device ED to a third operating state different from the first and second operating states.

[0228] For example, the device ED is configured to change the state of the device ED to the first operating state in response to the first limiting control signal CS2A. The device ED is configured to change the state of the device ED to the second operating state in response to the second limiting control signal CS2B. The device ED is configured to change the state of the device ED to the third operating state in response to the third limiting control signal CS2C.

[0229] For example, the device ED is configured to stop in the first operating state. In the first operating state, the device ED is configured to ignore or not respond to the operation signal SG1 transmitted from the operating device ST. Thus, the function of the device ED is limited in the first operating state. The electronic controller circuits EC1, EC2, or EC3 are configured to limit the function of the device ED based on the control signal CS2A.

[0230] Device ED is configured to operate at a first frequency in a second operating state. In the second operating state, device ED is configured to listen for an operation signal SG1 during a first time period and to ignore the operation signal SG1 during a second time period. Device ED is configured to repeat the first time period and the second time period at the first frequency. Accordingly, the functionality of device ED is limited in the second operating state. The electronic controller circuits EC1, EC2, or EC3 are configured to limit the functionality of device ED based on a control signal CS2B. The power consumption of device ED in the second operating state is higher than the power consumption of device ED in the first operating state.

[0231] Device ED is configured to operate in a normal manner in a third operating state. In the third operating state, device ED is configured to respond to the operation signal SG1. Accordingly, the functionality of device ED is not limited in the third operating state. The power consumption of device ED in the third operating state is higher than the power consumption of device ED in each of the first operating state and the second operating state.

[0232] In the third operating state, device ED is configured to operate in a first direction in response to a first operation signal included in the operation signal SG. Device ED is configured to operate in a second direction in response to a second operation signal included in the operation signal SG. The second direction is different from the first direction.

[0233] Device ED may be configured to operate in only one of the first direction and the second direction in the second operating state, rather than at the first frequency. In this case, the functionality of device ED is limited in the second operating state. The electronic controller circuits EC1, EC2, or EC3 are configured to limit the functionality of device ED based on a control signal CS2B. The power consumption of device ED in the second operating state is higher than the power consumption of device ED in the first operating state.

[0234] As needed or desired, at least one of the first limiting control signal CS2A, the second limiting control signal CS2B, and the third limiting control signal CS2C may be omitted from the control signal CS2. As needed or desired, at least one of the first operating state, the second operating state, and the third operating state may be omitted from the states of device ED.

[0235] As seen in Figure 19 the control signal CS21 includes at least: a first limiting control signal CS21A for limiting the functionality of device ED to a first operating state; a second limiting control signal CS21B for setting device ED to a second operating state different from the first operating state; and a third limiting control signal CS21C for setting device ED to a third operating state different from the first operating state and the second operating state.

[0236] For example, the device ED is configured to change the state of the device ED to a first operating state in response to the first limiting control signal CS21A. The device ED is configured to change the state of the device ED to a second operating state in response to the second limiting control signal CS21B. The device ED is configured to change the state of the device ED to a third operating state in response to the third limiting control signal CS21C. Thus, the electronic controller circuits EC1, EC2, or EC3 are configured to limit the function of the device ED based on each of the control signals CS21A and CS21B.

[0237] As needed or desired, at least one of the first limiting control signal CS21A, the second limiting control signal CS21B, and the third limiting control signal CS21C may be omitted from the control signal CS21.

[0238] As seen in Figure 19 the control signal CS22 includes at least: a first limiting control signal CS22A for limiting the function of the device ED to a first operating state; a second limiting control signal CS22B for setting the device ED to a second operating state different from the first operating state; and a third limiting control signal CS22C for setting the device ED to a third operating state different from the first and second operating states.

[0239] For example, the device ED is configured to change the state of the device ED to a first operating state in response to the first limiting control signal CS22A. The device ED is configured to change the state of the device ED to a second operating state in response to the second limiting control signal CS22B. The device ED is configured to change the state of the device ED to a third operating state in response to the third limiting control signal CS22C. Thus, the electronic controller circuits EC1, EC2, or EC3 are configured to limit the function of the device ED based on each of the control signals CS22A and CS22B.

[0240] As needed or desired, at least one of the first limiting control signal CS22A, the second limiting control signal CS22B, and the third limiting control signal CS22C may be omitted from the control signal CS22.

[0241] As seen in Figure 19 the control signal CS23 includes at least: a first limiting control signal CS23A for limiting the function of the device ED to a first operating state; a second limiting control signal CS23B for setting the device ED to a second operating state different from the first operating state; and a third limiting control signal CS23C for setting the device ED to a third operating state different from the first and second operating states.

[0242] For example, device ED is configured to change the state of device ED to a first operating state in response to a first limit control signal CS23A. Device ED is configured to change the state of device ED to a second operating state in response to a second limit control signal CS23B. Device ED is configured to change the state of device ED to a third operating state in response to a third limit control signal CS23C. Thus, the electronic controller circuits EC1, EC2, or EC3 are configured to limit the functionality of device ED based on each of the control signals CS23A and CS23B.

[0243] As needed or desired, at least one of the first limit control signal CS23A, the second limit control signal CS23B, and the third limit control signal CS23C may be omitted from the control signal CS23.
