On the other hand, control circuit 24 when the bright light switch 29 of differentiation is not connected, head lamp 20 is remained on the state of turning off the light, and taillight 22 also remains on the state of turning off the light (step S3).
Fig. 4 is expression is detected control action by the braking state of control circuit 24 execution a diagram of circuit.
According to the flow process of Fig. 4, if describe with reference to Fig. 2, then control circuit 24, monitor with the control cycle (interrupt routine) of the regulation state to BK Brake Switch 31.Then, whether be the braking state of operating brake lever 7 by the driver, whether connect according to BK Brake Switch 31 and differentiate (step S11).
Then, if BK Brake Switch 31 is connected, then control circuit 24 is made as regeneration mode (step S12) with inverter 14.If inverter 14 is made as regeneration mode, then be not by inverter 14 to motor 18 supply capabilities, but motor 18 plays a role as electrical generator, the counter electromotive force that produces by motor 18 from motor 18 to inverter 14 regenerative currents that flow.This regenerative current also is used in battery 11 is charged, and when taillight 22 conductings, with taillight 22 bright lamps.
On the other hand, control circuit 24 when differentiation BK Brake Switch 31 is not connected, is made as drive pattern (step S14) with inverter 14.Inverter 14 is provided for battery 18 with the electric power of battery 11 from inverter 14 under drive pattern, motor 18 is driven.

According to the detection control of as shown in Figure 4 braking state,, then, can report braking state easily expressly by taillight 22 with taillight 22 fast light on and off if BK Brake Switch 31 is switched on.And, owing to can therefore can suppress the power consumption of battery 11 by supply with the fast light on and off desired power of taillight 22 from the regenerated electric power of motor 18.
Then, the restriction control at the output current value of battery 11 describes.
Usually, the limits value of outgoing current is fixed in the battery 11.About limits value, exist to the restriction (being the instantaneous current limits value) of the transient peak about the several seconds with to the restriction (being average current limit) of the aviation value during long to a certain degree.In Electrical Bicycle 10, need under both sides' restriction, get maximum power from battery 11.
Therefore, in the Electrical Bicycle 10 of present embodiment, carry out the limits value control of so as shown in Figure 5 outgoing current.
In Fig. 5, the longitudinal axis is represented immediate current controlling valu and Average Current Control value, immediate current controlling valu〉the Average Current Control value.Transverse axis is represented stepping on and pedal action repeatedly.Step on for 1 time pedal action be meant from begin to step on pedal to step on pedal end till.Stepping on for this 1 time and pedal action, is to be undertaken by half rotation of a pedal 6 (for example right-hand tread plate), and ensuing once stepping on pedaled action, is to be undertaken by half rotation of another pedal 6 (for example left-hand tread plate).
In Electrical Bicycle 10, the pedal force that pedal 6 is applied is detected by pedal sensor 39.In control circuit 24, according to the pedal force that pedal sensor 39 is detected inverter 14 is controlled, and made the outgoing current increase and decrease of the battery of supplying with to motor 18 11.The output torque of motor 18 increases and decreases according to the increase and decrease of the outgoing current of battery 11.
In control circuit 24, according to the pedal force that is detected by pedal sensor 39, the auxiliary driving force (output torque) that motor 18 is produced increases and decreases.Rough, if the pedal force that pedal sensor 39 is detected is big, the auxiliary driving force that motor 18 is produced is big, if pedal force is little, then makes auxiliary driving force little.
The size of auxiliary driving force, proportional with the current value of supplying with to motor 18 from battery 11.Therefore, in control circuit 24, to monitoring, pedal in the course of action 1 time step on output current value is surpassed the amount (B1 among Fig. 5) of average current limit of the battery of predesignating 11 and the amount (A1 among Fig. 5) that is accommodated in the average current limit adds up according to the output current value of the battery 11 of the pedal force increase and decrease that obtains from pedal sensor 39 (current value that is detected by current sensor 35).
Then, when the high load capacities such as upward slope of fierceness, be B1 at the electric current aggregate-value of being obtained〉under the situation of A1, step at ensuing 1 time and to pedal in the action, the immediate current limits value is reduced certain value.Like this, for example pedal in the action (second step on pedal action) stepping on for ensuing 1 time, even detect and first step on and pedal the same pedal force of action, since second step on the immediate current limits value pedaled in the course of action than first step on pedal when moving low, so current average to step on the current average of pedaling during the action than first little.
Pedal in the action even step on second, also to the amount (B2 of Fig. 5) that surpasses average current limit and be accommodated in average current limit and add up with interior amount (A2 of Fig. 5), if still the electric current computing value is B2〉A2, then step on the instantaneous current limits value of pedaling action with the 3rd and further reduce certain value.The instantaneous current limits value can be faded to till the average current limit.
If the instantaneous current limits value drops to till the average current limit, then must average current limit be accommodated in the allowed value.
On the contrary, if certain steps on the amount Bn that surpasses average current limit pedaled in the action (the N time step on pedal action), and to be accommodated in average current limit be Bn ≦ An with the pass between the interior amount An, then the instantaneous current limits value can increase to the standard value of predesignating (maxim).
By continuing such control, even thereby the big state of load continues, also can observe to the restriction (restriction of instantaneous current limits value) of peak current value and to the restriction (restriction of average current limit) of average current value, can securely and effectively use battery 11.
In addition, instantaneous current limits value and average current limit, the temperature traverse that produces according to the use because of battery 11 changes.Thereby, in the present embodiment,, this detected temperatures and the current limit value form that sets in advance are contrasted by the temperature of temperature sensor 37 detection batteries 11, decide instantaneous current limits value (standard value) and average current limit.
Then, the flow process along the diagram of circuit of Fig. 6 and Fig. 7 describes the control action of carrying out in the control circuit 24 of reference Fig. 5 explanation.
At first, describe according to the flow process of Fig. 6, whether control circuit 24 is differentiated to begin to step on based on the pedal force that is provided by pedal sensor 39 and is pedaled (step S21).Then,, then begin to step on for 1 time the electric current accumulative total of pedaling during the action if detect to begin to step on and pedal, with the part below the average current limit as An, will be above the part of average current limit as Bn.In addition, n be n=1,2,3 ..., the order of pedaling action is respectively stepped in expression.Then, obtain and step on the end of pedaling action for 1 time and promptly step on electric current aggregate-value An and the Bn of pedaling till finishing to be detected (step S22, S23).
Detect step on pedal end after, the size (step S24) of electric current aggregate-value Bn and An relatively.
According to result relatively, at Bn〉under the situation of An, make the currency of instantaneous current limits value reduce the value (step S25) of regulation.
On the contrary, if Bn ≦ An confirms that then the currency of instantaneous current limits value does not become the standard value of instantaneous current limits value (maxim) (step S26), make the currency of instantaneous current limits value increase certain value (step S27).
In control circuit 24, on one side carry out as shown in Figure 6 control action, on one side concurrently detection begin to step on pedal step on to detection pedal end till during carry out current control according to the mode that is no more than instantaneous current limits value as shown in Figure 7.
Promptly, flow process according to Fig. 7, differentiate (step S31) to beginning to step on the detection of pedaling, detect in output and begin to step under the situation about pedaling, relatively from the current instantaneous value of current sensor 35 inputs and the size (step S32) of instantaneous current limits value based on pedal sensor 39.Then, under the current instantaneous value situation bigger than instantaneous current limits value, control inverter 14 makes the driving dutycycle of motor 18 reduce (step S33).
On the contrary, under current instantaneous value is situation below the instantaneous current limits value, the size of the torque output valve of torque indicated value that should provide to motor 18 and motor 18 relatively, if the motor torque indicated value is more than the motor torque output valve, then control inverter 14 makes the driving dutycycle of motor 18 increase (step S35).
On the contrary, if the motor torque indicated value is below the motor torque output valve, then control inverter 14 makes the driving dutycycle of motor 18 reduce (step S36).
Then, detect step on pedal end before, carry out the control (step S37) of step S32～S36.
By carrying out above action, thereby the pedal force that is detected by pedal sensor 39 is big more, and the torque output valve of motor 18 is big more, produces big more auxiliary driving force, and generation and the corresponding suitable auxiliary driving force of pedal force.And,, can control the current value that motor 18 is provided and also satisfy arbitrary restriction in instantaneous current limits value and the average current limit in order to produce auxiliary driving force.
The present invention is not the embodiment that is defined in above explanation, in the scope of claim record various changes can also be arranged.
