Abstract: PROBLEM TO BE SOLVED: To accurately detect a torque with a simple constitution by transmitting a driving force by a rotor changing at its relative position by the torque, detecting a change in a resonance frequency responsive to the change of the relative position without contact, and transmitting a modulation signal without contact. SOLUTION: An oscillator 61 oscillates a sine wave signal according to a resonance frequency of a resonator and outputs a signal so as to change an oscillation signal in response to a pedal power. In a motor driven bicycle 31, this sine wave signal is amplified by an output circuit 63, and then transmitted to a frame side through coupling elements 54A, 54B without contact. Then, an output signal of the element 54B is frequency divided by a frequency divider 66, then band-pass limited by a high-pass filter 67, and detected. This detected result is integrated by a low-pass filter 68, and a torque detection signal changed at its DC level in response to a frequency of the sine wave signal, i.e., the pedal power is detected. The torque can be detected without contact by detecting the resonance frequency changing according to the pedal power.

Abstract: PROBLEM TO BE SOLVED: To avoid a wheel base from becoming longer and a saddle position from becoming unreasonable, reduce the number of parts, and also avoid a chargeable battery from being damaged due to overturning. SOLUTION: In an electric bicycle where a part of a power for travelling is assisted by a motor 9 when it is moved by the operation of a rider, a battery storing space 11 is provided in a top tube 10, a cover body 13 to open and close the battery storing space is provided at the rear end of the top tube. Thus the cover body 13 can be opened and closed with a seat pillar 17 removed from a seat tube 12.

Abstract: PROBLEM TO BE SOLVED: To reduce the burden of main power and stabilize traveling by obtaining sufficient auxiliary power overcoming running resistance at the time of starting a moving device. SOLUTION: A moving device 1 is provided with an auxiliary power source 2 for assisting propulsive force in an advance direction generated by main power. At the time of starting the moving device 1 against running resistance, a power control means 3 computes auxiliary power for balancing the running resistance and propulsive force and adds it to the main power. In an assisted bicycle with a motor as an auxiliary drive source, for instance, in case of a wheel being reversely rotated at the time of starting on an upward slope, it is so controlled as to balance auxiliary power and slope resistance so as to facilitate slope start only by adding slight leg power (main power). The burden on a rider can therefore be lightened, and stable running can be guaranteed at the time of start.

Abstract: PROBLEM TO BE SOLVED: To provide assistance of stepping force properly on real time by providing a power assist means which assists power which corresponds to speed change information which an operator gives based on speed information obtained from a traveling information grasp means in a travelling device such as a bicycle provided with a motor. SOLUTION: When an electric bicycle is driven, a control means 100 grasps a traveling condition of the electric bicycle based on signals from a speed sensor 110, an inclination sensor 90, a crank rotation sensor 120, a front brake sensor 130, and a rear brake sensor 140. Moreover, it synthesizes acceleration information based on a speed signal Vs from the speed sensor 110 to realize power assist which is failthful to a will of an operator for a power assist means 30. That is, traveling power is calculated from speed information and inclination information, acceleration information is obtained based on the speed signal Vs, and real time assist amount is determined by adding an acceleration traveling power value and a fixed speed traveling power value based on the acceleration information.

Abstract: PROBLEM TO BE SOLVED: To charge a battery effectively to prolong traveling distance by providing a function change-over control means which makes a motor function as a generator when a situation of a road surface does not necessitate assistance of a part of force for moving a travelling device such as a bicycle provided with the motor in the travelling device. SOLUTION: In a function change-over control means of a motor 31, a coil cut relay part 200 is turned on and a relay part for charging circuit 250 is turned off when a running road surface is a climbing slope. When the traveling road surface is flat and inertia running is possible, the coil cut relay part 200 is turned off and the relay part for charging circuit 250 is also turned off. On the other hand, when the traveling road surface is down slope, the coil cut relay part 200 is turned off and the relay part for charging circuit 250 is turned on. Consequently, when the traveling road surface is down slope, the motor 31 functions as a generator, and induction power generated when the motor 31 functions as the generator is charged into a battery 40 through the relay part for charging circuit 250 and a charging circuit 300 of the battery.

Abstract: PROBLEM TO BE SOLVED: To detect an overall mass of a vehicle having a moving unit from detected information of its motion in the unit having an auxiliary power source. SOLUTION: The moving unit 1 has an auxiliary power source SS for a main power source MS, and moves together with a drive subject of the power source MS. An acceleration 'at' of a vehicle (moving object having the unit 1 and the subject) of the case of driving the power source SS by a predetermined force 'Fa' and an acceleration 'αn' of the vehicle of the case of driving the power source SS by a force 'Fa'' different from the force 'Fa' are detected. An overall mass 'M' of the vehicle is calculated as a value of a ratio of dividing a difference 'Fa-Fa'' of the force by the power source SS by difference information 'αt-αn' of the accelerations, an auxiliary power value is obtained from this, and the power source SS is controlled.
