Fig. 6 is the constructional drawing of key.
Below according to view embodiments of the invention are described.State because of the side of the outward appearance of the electronic manned golf cart of Fig. 1 is the same bright the same, the Therefore, omited.In Fig. 2, the power supply (battery pack) 11 that a plurality of driving motors 13 and other motors are used is installed on body shell 4.On the axletree of trailing wheel 3, driving motors 13 is installed on change speed gear box 12.
Again, the present invention is mounted with the driving motors 13 of unexistent novel structure on existing electric golf cart and as the power-generation charging device 10 of the charging usefulness of the power supply (battery) 11 of the propulsion source of other motors.And, on body shell 4, dispose control single-piece control circuit portion 9.
According to Fig. 3 the electronic manned structure of using the control system of golf cart is described.Switch with (HM) motor 16 by driving motors 13, main brake (MB) motor 14, stopping brake with (PB) motor 15, automatic/hand and turn to control with (SM) motor 17 formations as the motor part of power part.
The power supply of power part (battery pack) 11 is connected with power system through current detection circuit 24.Detect the charging current of power supply (battery pack) 11 or any in the discharge current with current detection circuit 24, according to the instruction of host CPU 23, with the electrical generator 10a of generator control circuit 25 control power-generation charging devices 10.
Power-generation charging device 10 is to constitute like this, promptly on the output shaft as the engine of propulsion source electrical generator 10a is installed, and is to be made of Starting motor and choke coil control part that the engine to propulsion source starts.Spontaneous motor 10a is to be connected with the terminal of charger 10b behind the vdc by AC voltage conversion.Again, config memory 26 on host CPU 23, are used to store charging current value, the discharge current value that periodically detects with current detection circuit 24.
The control system of turning part have coil pickup, with the moment of torsion sensor of bearing circle interlock and not shown steering motor, torque sensor is as the device configuration that detects the steering operation amount.
Again, on electric golf cart of the present invention, the switch that model selection is used is configured to and key (with the golf cart power supply main switch that the switch branch is arranged such as begin to travel, the stop) mode of interlock jointly.The example that Fig. 6 represents is exactly that key 30 has the turning cylinder 31 that rotates together with knob 32." electrical generator stop mode ", " OFF " and " charge mode " that knob 32 can be selected solid line position " general driving mode ", be represented by dotted lines.Can utilize this key 30 to come the ON/OFF propulsion source to reach the circuit that leads to control circuit, and can select above-mentioned each pattern.
Carry out under the situation of manual operation at electric golf cart this structure, after the changer lever that will turn round automatically is made as " manually ", become manual driving mode, with common manned the same as the direction of operating dish with golf cart, make the device action that detects button square sensor steering operation amount, through host CPU 23 steering motor is rotated to left, above-mentioned torque sensor is according to the rotating to the left or to the right amount of bearing circle and corresponding turning to.And the operation of the operation of direction of passage dish (turning to) and throttle, drg just can advance, retreat according to linksman's oneself operation.
Secondly, under automatic travel situations, after the changer lever that will turn round automatically is made as " automatically ", become automatic driving mode.At this moment, the inducing current that on the return line of burying underground along golf track (travel), flows as induced signal, with about coil pickup detect, after amplification, detection, obtain differential output through differential amplifier, with analog signal input host CPU 23, handle the ridden in left or right direction direction.
Again, read according to being embedded in the magnet array on the golf track (travel) and the speed that produces, information such as stop, according to carrying out automatic guidance and automatic deceleration, stop automatically in the instruction limit of host CPU 23, sail in that the golf track is up on the limit.In addition, by remote control or advance/operation of stop button also can advance, stop in arbitrary site.Again, utilize various safety devices such as golf cart protection detecting device to detect dangerous situation after, promptly stop.Especially under the situation of utilizing golf cart protection detecting device, because of stopping action automatically, so can and front truck between maintenance certain intervals and stopping.
The golf cart of the present invention that as above, constitutes, no matter (also comprise descending) under steam, still be in stopping, in often with the discharge current value and charging current value of current detection circuit 24 supervision, periodically detected charging current value, discharge current value are stored in the memory device 26 as the power supply (battery pack) 11 of propulsion source.At this, why be conceived to charging current value and discharge current value, even be owing under the situation that external causes such as load variations disturb, also can detect stable battery charge, discharge regime, but also can monitor and prevent the cause of battery overcharge.
When the linksman goes to " the general driving mode " of solid line position with the knob 32 of the key 30 of Fig. 6, foundation and one play the position signal of the turning cylinder 31 of rotation, after host CPU 23 was judged as general driving mode, the golf cart limit was carried out following general charging action limit and is travelled.
Promptly, in golf cart travels, host CPU 23 judges on current detection circuit 24 that discharge current value increases and when becoming charge volume big, battery and reducing, and starting (ON) is charged to battery pack 11 by charger 10b to the engine that the electrical generator 10a of power-generation charging device 10 drives.Then, check charging current values,, engine is stopped, the complete charge action when discharge current value is reduced to specified value when following with current detection circuit 24.Like this, when each golf cart begins to travel, just check discharge current value, carry out same charging action with current detection circuit 24.
If golf cart is in the words in stopping, then start the engine that the electrical generator 10a to power-generation charging device 10 drives, after determining the engine starting, check charging current value with current detection circuit 24, if charging current value surpasses specified value, through electrical generator 10a, charger 10b battery pack 11 is charged, charging action continue to charging current value be reduced to specified value following till.Again, check charging current value with current detection circuit 24, if charging current value is lower than specified value, then make engine stop (OFF), golf cart is waited for halted state.Then, if begin to travel again, then check discharge current value with current detection circuit 24.
In addition, because of monitor the discharge current value and the charging current value of power supply (battery pack) 11 with current detection circuit 24 always, and charging current value, the discharge current value that is detected periodically stored in the memory device 26, so no matter golf cart under steam, still in stopping, all can grasp the charge condition of battery pack, after date when being transformed into charging can positively carry out additional charge.Especially, in golf cart stops, because of starting engine especially with the charge volume of confirming battery, so can not produce unnecessary noise in order to detect charging current value.
Again, because of the engine of power-generation charging device 10 produces noise in driving, so when playing golf the linksman wish that Keep silence in whole bout, when concentrating on, after the knob 32 of key 30 gone to " the electrical generator stop mode " shown in the dotted line, foundation and one play the position signal of the turning cylinder 31 of rotation, host CPU 23 stops the action of charging at any time under steam, is controlled to only to rely on the power supply of electrically-charged battery pack to travel.Thereby, can not be subjected to the engine acoustic jamming, can undisturbedly enjoy the enjoyment that plays golf.
After using " electrical generator stop mode " to finish whole bout, the amount of being of holding of battery pack almost consumes and is over certainly, so need to charge in order to travel next time.Therefore, before being received into the golf cart chamber, the knob 32 of key 30 gone to " charge mode " shown in the dotted line after, foundation and one play the position signal of the turning cylinder 31 of rotation, even golf cart is in stopping, host CPU 23 also instructs and carries out set charging action.
That is, starting (ON) is charged to battery pack 11 by charger 10b to the engine that the electrical generator 10a of power-generation charging device 10 drives.Then, check charging current values,, engine is stopped, the complete charge action when charging current value is decreased to set value when following with current detection circuit 24.
Again, under the situation of general driving mode, the charging of battery pack utilizes the regenerative brake of the driving motors 13 of golf cart when brake also can charge a little except utilizing power-generation charging device 10.Like this, the present invention charges to battery pack 11 in the electric golf cart chamber of golf course, but utilizes power-generation charging device 10 to charge at any time on running route.Again, power-generation charging device also can utilize small fuel cell.
Following elder generation illustrates the generating-charging control of electric golf cart under general driving mode situation as object of the present invention according to the flow process of the generating-charging control sequence of Fig. 4.In Fig. 4,, whether under steam to judge golf cart at step S1 by step S0 generating-charging control beginning.
If under steam, then move to step S2, judge the size of discharge current (discharge rate) at step S2.Under the little situation of discharge current, judge that discharge rate is little and after needn't additional charge, repeat to judge the size of discharge current equally.Under the big situation of discharge current, it is big to be judged as discharge rate, then moves to step S3, the engine that starting (ON) generator drive is used.
At step S4, judge whether engine has started.If under the situation of engine unstart (NG), move to step S3 again, the engine that starting (ON) generator drive of trying is used.If judge that engine has started, then move to next procedure S5, judge the size of discharge current (discharge rate).
If under the big situation of discharge current, judge that discharge rate is still big, repeat to judge the size of discharge current equally.If under the little situation of discharge current, it is little and after not needing to carry out unnecessary additional charge, move to step S6 to be judged as discharge rate, and the engine that generator drive is used stops.Then, get back to step S1, repeat same control action.
At step S1, if judge that golf cart in stopping, then moving to step S7, the engine that starting (ON) generator drive is used.Then, at step S8, judge whether engine has started.If under the situation of engine unstart (NG), move to step S7 again, the engine that starting (ON) generator drive of trying is used.If being judged to be engine has started, then move to next step S9, judge the size of charging current (charge volume).
If still little, similarly repeat to judge the size of charging current at the big situation of the charging current charge volume that judges.Under the little situation of charging current, after the judgement charge volume needs greatly and not to carry out unnecessary additional charge, move to step S10, the engine that generator drive is used stops (OFF).
After the engine that generator drive is used stops, whether under steam to judge golf cart at step S11.If be judged to be golf cart in stopping, then repeating same acts of determination.In the judgement of step S11, if golf cart begins to have travelled, then move to step S2, repeat the master mode in above-mentioned the travelling.
The flow process of the selection control sequence of " charge mode " in the various patterns of generating-charging control in the generating-charging control sequence when secondly, explanation is attached to generally travelling of Fig. 4 with reference to Fig. 5, electric golf cart of the present invention, " general driving mode " and " electrical generator stop mode ".
In Fig. 5,, judge whether be charge mode at step S21 from step S20.If charge mode then moves to step S22, the engine that starting (ON) generator drive is used.Then, judge at step S23 whether engine has started.If under the situation of unstart (No), return step S22, the engine that starting (ON) generator drive of trying is used.If judge that engine has started, then move to step S24, judge the size of charging current (charge volume).
Still need charging as if judging, similarly repeat to judge the size of discharge current in the big situation of charging current.Judge after charge volume needs greatly and not to carry out unnecessary additional charge in the little situation of charging current, move to step S25, the engine that generator drive is used stops (OFF) action.
At step S21, if judge it is not charge mode, then move to step S26, judge whether be general driving mode.If be judged as general driving mode, then move to step S27, general driving mode is controlled according to the flow process of the generating-charging control sequence of Fig. 4.If judge it is not general driving mode, move to step S28, the engine that generator drive is used stops action (OFF).
As mentioned above, golf cart of the present invention, utilize on the golf cart the cargo-carring power-generation charging device that constitutes by power generation assembly and charging unit, charging voluntarily at any time on the running route that plays golf, so just, can prevent to play golf for a long time or special when running of travelling causes and can't travel because of the power supply capacity deficiency, can save the high-capacity charging unit of golf cart chamber again, and by selecting " electrical generator stop mode ", can prevent the engine noises of power generation assembly, make the linksman in whole bout, quietly concentrate on playing ball in the environment.
Again, after using " electrical generator stop mode " to finish whole bout, travel and need battery pack be charged in order to prepare next, so before having played ball afterwards, being accommodated in the golf cart chamber, when selecting " charge mode " to batteries charging, because of the charging current of battery reaches just generation outage machine running behind the specified value, so can prevent undue charging really.In addition, so the form that is configured to common interlock because of switch that model selection is used and key is with the just changeable pattern of simple structure.
