In order to describe technical characterstic of the present invention place in detail, lift following preferred embodiment and coordinate accompanying drawing explanation as after, wherein:
As shown in Figures 1 to 4, the morpet that the present invention's the first preferred embodiment provides reduces the shifting system 10 of motor rotary speed while gearshift, be arranged on a morpet 90 with mid-motor 91 and selector 93, this shifting system 10 is mainly made up of a power module 11, a micro computer 21, a gearshift actuator 31 and a speed of a motor vehicle sensing module 41, wherein:
This mid-motor 91 is located at the vehicle frame of this morpet 90 and corresponding to Five-way tube, is driven trailing wheel so that power-assisted to be provided by a chain 92.
This power module 11 can be a battery, in order to power supply to be provided.
This micro computer 21, is electrically connected at this power module 11 and this mid-motor 91, in order to control output power-assisted and the rotating speed of this mid-motor 91.
This gearshift actuator 31, is electrically connected at this micro computer 21 and entity and is connected in this selector 93, is subject to the control of this micro computer 21 to drive this selector 93 to shift gears.
This speed of a motor vehicle sensing module 41, is electrically connected at this micro computer 21, in order to the speed of a motor vehicle of this morpet 90 of sensing.When enforcement, this speed of a motor vehicle sensing module 41 at least has the sensor for vehicle speed sensing.
This micro computer 21 has a motor rotary speed control logic 22 and the corresponding table 24 of one speed of a motor vehicle/motor rotary speed.In the process of gearshift, with self shifter or electric gear change system, its gearshift this micro computer 21 of serving as reasons opportunity judges voluntarily and should shift gears or when receiving rider's shifting commands, this micro computer is also carried out this motor rotary speed control logic 22, and coordinates this gearshift actuator 31 of control to shift gears.The corresponding table 24 of this speed of a motor vehicle/motor rotary speed for driving the required motor of these morpet 90 difference to drive rotating speed under multiple different speed of a motor vehicle.
The content of the corresponding table 24 of this speed of a motor vehicle/motor rotary speed is take table 1 as example, and this table 1 is the morpet corresponding to 7 fast speed changes.
In table 1 because motor rotary speed must match with gear with the speed of a motor vehicle, therefore at different gears and under the identical speed of a motor vehicle, motor rotary speed also can be different.
As shown in Figure 3, this micro computer 21 in the flow process of carrying out this motor rotary speed control logic 22 is:
(1), according to the corresponding table 24 of this speed of a motor vehicle/motor rotary speed, find out the corresponding motor of the current speed of a motor vehicle and drive rotating speed;
(2) controlling this mid-motor 91 makes rotating speed lower than the rotating speed of the corresponding motor driving of the speed of a motor vehicle at present, as shown in Figure 4, but still maintain the running of this mid-motor 91, so that the propulsive effort of this mid-motor 91 cannot be passed to this morpet 90 and just as idle running, now this mid-motor 91 does not provide propulsive effort by chain 92;
(2.1) controlling this gearshift actuator 31 shifts gears;
(3), after having shifted gears, control this mid-motor 91 and make its motor returning back to before gearshift drive rotating speed.
In the present embodiment, aforementioned flow process (2) makes rotating speed lower than the rotating speed of the corresponding motor driving of the speed of a motor vehicle at present at this mid-motor 91 of control, be control this mid-motor 91 make its rotating speed be the corresponding motor of the current speed of a motor vehicle drive rotating speed 90%～10%, and with 90% for better.
Again, aforesaid motor rotary speed control logic 22 flow processs are sequentially to carry out, but, except sequentially carrying out, also can add the interval of some times.For example, aforesaid flow process (2.1), is just to carry out through one first schedule time after flow process (2) completes, and this first schedule time is take 0.1～0.5 second as example.And aforesaid flow process (3) is just to carry out through one second schedule time after flow process (2.1) completes, this second schedule time is take 0.1～0.5 second as example.
Thus, this micro computer 21 is in the process driving, in the process of shifting gears, can first the rotating speed of this mid-motor 91 be turned down and make it just as idle running, propulsive effort cannot provide to this morpet 90 via chain 92, and then the problem that the interlock that can avoid prior art may suffer from because still having high power-assisted in shift process has some setbacks, chain breakage or change-speed box damage.And owing to just the rotating speed of this mid-motor 91 being turned down rather than being stopped, therefore after gearshift completes, mid-motor 91 is returned back to should have the required time of rotating speed shorter (for example, rotating speed returned back to for 100% required time by 90%, can specific speed to return back to for 100% required time by 0% short), and then can allow user feel that the speed of power-assisted reply is very fast, do not have the sensation of delay.
Referring again to Fig. 5 to Fig. 7, a kind of morpet that the present invention's the second preferred embodiment provides reduces the shifting system 10 ' of motor rotary speed while gearshift, be mainly generally same as aforementioned the first embodiment, and difference is:
The first embodiment is that morpet take self shifter or electric gear change is as example, and this second embodiment is that morpet take manual shift is as example, therefore this second embodiment does not have gearshift actuator, but separately there is a gearshift motion detector 19 ', be located at this selector 93 and be electrically connected at this micro computer 21 ', in order to detecting gearshift action.
As shown in Figure 5 and 7, the flow process of the motor rotary speed control logic 22 ' of this second embodiment, does not have the flow process (2.1) in the first embodiment, but only has flow process (1), (2) and (3).Wherein, these flow processs, except can sequentially carrying out, also can add time gap, and for example, this flow process (3) is just to carry out through one the 3rd schedule time after flow process (2) completes, and the 3rd schedule time was take 0.1～0.5 second as example.
Thus, this second embodiment can, in the process of manual shift, reduce the rotating speed of this mid-motor, still can reach effect of aforementioned the first embodiment.
Must additional description be a bit, in the first embodiment, owing to being applied in the technology of self shifter or electric gear change, gearshift is controlled by this micro computer, therefore can, in whole shift process, before starting, gearshift action just start to carry out motor rotary speed control logic.But in this second embodiment, owing to being the technology that is applied in manual shift, therefore gearshift is undertaken by selector, therefore can after gearshift action starts, just be detected by this gearshift motion detector 19 ' institute, then start to carry out motor rotary speed control logic by this micro computer.Even just carry out motor rotary speed control logic after gearshift action has started, still can effectively reduce motor rotary speed gearshift is also become as smooth and easy, the problem of solution known technology.
All the other technology of this second embodiment and the effect that can reach are all generally same as aforementioned the first embodiment, hold and no longer give and repeating.
Referring again to Fig. 8 to Figure 15, the morpet that the present invention's the 3rd preferred embodiment provides reduces the shifting system 50 of motor rotary speed while gearshift, be mainly generally same as aforementioned the first embodiment, and difference is:
This second embodiment, except the technology of the first embodiment, also combines pedal position as factor of judgment.
This second embodiment also includes: a pedal position sensing module 51, be located at least one crank 95 corresponding to this morpet 90 on this morpet 90 (in the present embodiment quantitatively take one as example, but two cranks are also applicable, be not limited in one), and be electrically connected at this micro computer 61, this micro computer 61 is the angle positions of learning this crank 95 by this pedal position sensing module 51.
As shown in Figure 10 to Figure 12, this micro computer 61 is in the time carrying out this motor rotary speed control logic 62, in flow process (1), except the technology described in the first embodiment, while also passing through one first angle position P1 in the angle position of this crank 95, reduce output power-assisted to the one first power-assisted value of this mid-motor 91; In flow process (2), leave after the P1 of this first angle position in the angle position of this crank 95, and while trampling dead point by one, this micro computer 61 is down to minimum by the output power-assisted of this mid-motor 91.And in flow process (3), after gearshift completes, the output power-assisted that this micro computer 61 is controlled this mid-motor 91 is returned to flow process (1) power-assisted size before.
In this second embodiment, aforesaid the first angle position P1 is take pedal position as 0 degree or the angle positions of 90 degree as example, wherein pedal position vertex is defined as 0 degree.The aforesaid dead point of trampling is the angle position of trampling moment this crank 95 when minimum, and is pedal position vertex (0 degree) or nadir (180 degree).Aforesaid the first power-assisted value is 30% of the highest output power-assisted of motor value.
Thus, except the technology of the first embodiment and the effect that can reach, what this second embodiment also combined pedal tramples position as factor of judgment, and coordinate the reduction of power-assisted value to shift gears, and after completing, gearshift again power-assisted value is improved, and then can be except motor rotary speed, also control power-assisted value and coordinate and shift gears, enter to make shift process also for smooth and easy.
As shown in FIG. 13 to 15, the adjustment of aforementioned power-assisted value, also can also have and further change: by adjusting this motor rotary speed control logic 62 ' (being shown in Fig. 8), in flow process (1) afterwards, also comprise a flow process (1.1) in the time that one second angle position P2 is passed through in the angle position of this crank 95, reduce output power-assisted to the one second power-assisted value of this mid-motor 91; And in flow process (2), whether the angle position of this crank 95 do not left this first angle position P1 and be down to minimum judgement as motor output power-assisted, but change into after this second angle position P2 is left in the angle position of this crank 95, and while trampling dead point by one, this micro computer 61 is down to minimum by the output power-assisted of this mid-motor 91.
Aforementioned the second angle position P2 is to spend as example take 45 degree or 135 of pedal position.
Aforesaid the first power-assisted value be take the highest output power-assisted of motor value 50% as example; This first power-assisted value is 30% of the highest output power-assisted of motor value; The output power-assisted of this mid-motor 91 is down to when minimum, is 10% of the highest output power-assisted of motor value.
Thus, the reduction of power-assisted value is not one-time-reach-place, but is divided into gradually having reduced of the first power-assisted value and the second power-assisted value.
All the other technology of this second embodiment and the effect that can reach are all generally same as aforementioned the first embodiment, hold and no longer give and repeating.
What must supplement is a bit, in the corresponding table 24 of this speed of a motor vehicle/motor rotary speed, there is the corresponding motor of each speed of a motor vehicle and drive rotating speed, if and when there is the morpet current speed of a motor vehicle and not listing in the corresponding table 24 of this speed of a motor vehicle/motor rotary speed, can make this micro-brain select to approach most the speed of a motor vehicle in the table of the current speed of a motor vehicle, again or can also first find out the current speed of a motor vehicle and be arranged in two vehicle speed values that table is adjacent, re-using the linear mode of calculating calculates corresponding motor and drives rotating speed.
