Illustrative program circuit

Figure 14 be computer 282 control various 100 components of bicycle and/or operation with optimize user firmly or at certain It is used under a little situations based on data auxiliary received from such as user apparatus 274, hand handle control unit 286, and/or sensor 288 The diagram of the exemplary process 300 at family.For example, user characteristics, physiology such as input by user and biological information are based on Element is determined by computer 282 --- such as holding by the program instruction, calibration of calibration process stored in memory Row --- and/or measured by sensor 288 and be stored in the memory of computer 282, together with being stored in computer Instruction, algorithm, program and formula in 282 memory, the computer 282 of bicycle 100 can determine motor output And provide such as starting auxiliary force at the parting of the ways and/or when climbing, riding rhythm optimization and the optimization of bicycle slant range Such feature.

The illustrative program 300 starts in a block 310, and wherein user characteristics pass through computer 282, sensor 288, use Family device 274 and/or hand handle control unit 286 are measured and/or are updated and stored in the memory of computer 282.User is special Sign may include, for example, physiological and biological information factor such as tramples power, pedal force, tramples rhythm, weight, relaxes Appropriateness, technology of riding, aerodynamic form, clothes and constitution level etc..In one example, it pedal force and is trampled to measure The user characteristics of rhythm, computer 282 may include software or instruction, for determining test or calibration procedure or mode, In these factors be measured directly (for example, trampling rhythm) and/or determine (for example, trampling with applied change in torque Power).In such illustrative embodiment, measured user's performance value --- it for example tramples rhythm and tramples torsion Square --- it can be set and be stored by the group of one or more data arrays in its memory by computer 282, Automatic calibration order as defined in each is also stored in its memory.User characteristics can by one or more data arrays into Row calculates.In another example, user can by user apparatus 274 and/or hand handle control unit 286, by manual access, or By measured value using other software, the storage of mechanism or machine (for example, fixed bicycle or other exercise devices) or The determination of user characteristics inputs or transmits user characteristics.Other users feature can be still directly measured, such as weight.Another In one example, which can be pre-stored in the memory of computer 282 and the bicycle is based on bicycle 100 measured value used or new test or calibration mode operation are to update user characteristics.

In the determined situation of user characteristics, which continues in a block 320, and the wherein computer 282 determination comes from Motor 280 is used for the operating conditions of bicycle 100 --- for example, the gradient of road, current speed, and/or bicycle 100 With the degree of approach of other vehicles --- power distribution, can be sensed by sensor 288.For example, if voluntarily Vehicle 100 is configured as offer power-assisted in accelerator at the parting of the ways and is travelled at a slow speed with helping to avoid user, then should be certainly Driving 100 can be from measured speed lower than identifying accelerated events in specific storage threshold value and as being higher than some threshold value Rhythm and/or power are trampled in measurement.Using such as weight, pedal force and user characteristics as rhythm are trampled, the calculating Machine 282 can be determined for the selectable parameter of motor controller 284 and/or instruction to activate motor 280 and make certainly The operation of driving 100 is in user characteristics and other parameters, is such as stored in computer 282 from sensor 288 Control threshold and data in memory.Control threshold may include, for example, secure threshold --- such as maximum speed or Bicycle angle or comfort threshold --- such as maximum pedal force accelerates rate.

In the determined situation of instruction for controlling motor 280, next, in frame 330, the computer 282 And/or motor controller 284 operates motor 280 according to instruction.In frame 340, which determines the control function Whether continue, for example, whether the bicycle 100 has arrived at its terminal.If the control of the computer 282 does not continue, example Such as, which has had arrived at its terminal and/or has closed, then the program 300 terminates.It, should if the control continues Program 300 proceeds to frame 350, and wherein the computer 282 determines whether the user characteristics are updated.If the user characteristics will It is updated, for example, the computer 282 is being designed to run under the health keeping mode for adjusting the energy level of user, then the journey Sequence 300 returns to frame 310.If the user characteristics are not updated, for example, the computer 282 is based only upon static user spy Sign --- weight of such as user --- is run under power preservation mode, then the program 300 returns to frame 320.

In an illustrative embodiment, which can optimize battery life by program 300, For example, the computer 282 can be continuously updated user characteristics with re-optimization power transmission in order to maximizing bicycle Energy.In other embodiments, the bicycle 100 and computer 282 can permit user and determine computer 282 in much degree The upper instruction determined dependent on user characteristics under given operation mode for the operation of motor 280.In additional example, The operational mode can have different objective results, such as training mode, wherein the instruction of the operation for motor 280 is pressed Training or body-building demand according to user determine；Cruise mode control, wherein for example by hand handle control unit 286, speed input is logical The route conditions for crossing variation are maintained；Accelerate boost mode, wherein power be provided on such as crossroad or hillside with In the reduction acceleration time and/or firmly；Foot-operated Optimizing Mode, wherein the power assisted is conditioned so that bicyclist can remain pre- Setting or the optimization rhythm measured trample power；Refresh charging, the wherein power and control system 250 and/or motor 280 Including regenerative power mechanism to be that power supply 260 recharges in descending or moderating process；And continuation of the journey Support Mode, wherein presetting Or measurement terminal be entered and the bicycle optimization performance be able to maintain that with the cruising ability for ensuring the power supply 260 Terminal.In another example, operation mode can be predetermined with by the performance adjustment of bicycle 100 to specific style, for example, Faster accelerate in " innervation " setting under any appropriate operation mode.Similarly, exemplary process 300 can provide various Rhythm is trampled, without respectively debugging the transmission device of bicycle 100.
