Below with reference to control flow chart as shown in Figure 6, the control action mode of the front-wheel auxiliary motor among the present invention with driving circuit described.In this diagram of circuit, be to describe with the example of only output valve of motor force being implemented to set.
Begin this control action program at program step S0,, judge whether the prop stand 19 on the bicycle is in (uprightly) state of falling subsequently at program step S1.When prop stand 19 being in fall (uprightly) state, lifting test section (microswitch) 34 can input to control circuit 42 by this signal of falling state of expression.If prop stand 19 remains on the state of falling continuously, then enter to program step S2, making electric driving force K is 0, does not promptly produce underaction by motor force.
If when prop stand 19 is risen, enter to program step S3, judge whether trailing wheel is in float state (whether load being arranged at the trailing wheel place).If trailing wheel is in float state, will represent that with detection components (deformation strain meter) 18 trailing wheel is in the signal of float state, inputs to control circuit 42 by the trailing wheel float state.And when detecting trailing wheel and be in float state, enter to program step S2, making electric driving force is 0, does not promptly produce underaction by motor force.
If being trailing wheel, the result of determination of program step S3 is not in float state, when promptly detecting load, enter program step S4, the signal A that moment sensor 48 is provided inputs to control circuit 42, and by program step S5, to incoming signal A and the electric driving force K that provides by moment sensor 48, whether satisfy the condition of electric driving force K 〉=torque signals A and implement relatively.If electric driving force K 〉=torque signals A then sets electric driving force K=torque signals A, and is back to program step S1, judge whether prop stand 19 is in the rise state.
For the incoming signal A that provides by moment sensor 48 occasion different, enter to next step with electric driving force K.Such as,, adopt step-by-step system gently to increase the output signal of drive division if judge that the power that inputs to front-wheel 5 for foot-operated power, then enters program step S6 for the bigger occasion of incoming signal A that the manpower applied moment produces.Promptly increased after 1 when output signal, be back to program step S5, and the time once more by this part, at first by the time increase by 1 on the output signal 1, reach 2.Implement this process continuously, just can As time goes on slowly gather way.Therefore, can realize so-called soft start.
After beginning to advance, by program step S5 incoming signal A and the electric driving force K that moment sensor 48 provides compared, if the incoming signal A that is provided by moment sensor 48 is littler than electric driving force K, promptly step on and pedal when the force rate at pedal 7 places is more weak, enter to program step S7, implement control according to the mode that the output K that electric driving part is provided is identical with moment sensor 48 detected manpower effect sizes.
In traveling process, also often whether prop stand 19 is in the rise state and implements to judge (program step S1), whether trailing wheel is in float state implements to judge (program step S3), if because prop stand 19 is in the state of falling in traveling process, prop stand 19 may contact with ground and produce danger, if owing to the convex-concave fluctuating of road is floated trailing wheel, front-wheel may be in extended state and produce danger, so in case these situations occur, just can make electric driving force K is 0 (program step S2), stops the rotation of auxiliary motor.
In aforesaid embodiment, be that the front wheel driven electric bicycle that changes the electric driving part propulsive effort in order to personnel selection power effect moment is that example describes, yet the present invention is not limited in this form, can also constitute when implementing quicken to wait operation the Electrical Bicycle that the propulsive effort of electric driving part is changed such as the user.
