The present invention is an application with the golf cart that can travel automatically mainly, but at this, and display application is in selecting to travel automatically and the example of the electronic carrying golf cart of manual operation.Fig. 1 is the in-built planar view of expression electric golf cart for the lateral plan of the outward appearance of expression electric golf cart of the present invention, Fig. 2, and Fig. 3 represents its control system structure.
Below record and narrate embodiments of the invention according to accompanying drawing.Because of the explanation of the side of the outward appearance of the electric golf cart of Fig. 1 as mentioned above, the Therefore, omited.In Fig. 2, a plurality of power supplys (battery) 11 that travel and use with motor 13 and other motor are installed in vehicle body frame 4.On the axletree of trailing wheel 3, travel with motor 13 in change-speed box 12 installations.
Again, the invention is characterized in, loaded the new structure, the i.e. conduct that on existing electric golf cart, are provided with and travelled with the generating/charging unit 10 of the charging usefulness of the power supply (battery) 11 of the propulsion source of motor 13 and other motor.And, on vehicle body frame 4, disposed control single-piece control circuit portion 9.
According to Fig. 3 the control system structure of electronic carrying with golf cart is described.Switch with (HM) motor 16 with (PB) motor 15, automatic/hand and turn to control with (SM) motor 17 formations with motor 13, foundation brakes (MB) motor 14, parking brake by travelling as the motor part of power part.
With motor 13 motor control part 18 is set travelling, and the configuration current detection circuit.Again, foundation brakes motor control circuit portion 19 is set at foundation brakes motor 14, and configuration current detection circuit and brake position sensor.The control part 20 of parking brake with motor 15 is set, and the configuration current detection circuit.Switch the control part 21 configuration detection circuit of using motor 16 at automatic/hand.Turning to control control part 22 to be set, utilize host CPU 23 (micro computer) to control each motor with motor 17.
The power supply of power part (battery) 11 is connected with power system via current detection circuit 24.With the charging current or the discharge current of current detection circuit 24 detection power supplys (battery) 11, control the electrical generator 10a of generating/charging units 10 with generator control circuit 25 according to the instruction of host CPU 23.
Generating/charging unit 10 is at the structure that electrical generator 10a has been installed as the output shaft of the engine of propulsion source, constitutes with the battery motor and the choke coil control part of the engine of starting propulsion source.Spontaneous motor 10a is to be connected with the terminal of charger 10b behind the vdc by AC voltage conversion.Again, the charging current value that periodically detects with current detection circuit 24 in order to storage in host CPU 23 configurations, the memory device 26 of discharge current value.
The control system of turning part has the torque sensor of coil pickup and bearing circle interlock, not shown turning to uses motor, torque sensor to be configured to detect the device of the operational ton that turns to.
Use under the situation of golf cart in the carrying of this structure of manual operation, after the changer lever that will turn round automatically is made as " manually ", become manual driving mode, the same as the direction of operating dish with general carrying with golf cart, rotation to the left or to the right according to bearing circle, the device action of the operational ton that the detection of torque sensor turns to turns to motor via host CPU 23 order and to rotate to left.And, through the operation of the operation of bearing circle and throttle, drg, can advance, retreat according to linksman's operation.
Secondly, under the situation of travelling automatically, after the changer lever that will turn round automatically is made as " automatically ", become automatic driving mode.At this moment, be induced signal with the inducing current that flows at the loop line of burying underground along transport trolley road (travel), the coil pickup about using detects, after amplification, detection,, obtain differential output via differential amplifier, with analog signal input host CPU 23, the travel direction about manipulation.
Again, through the speed that reads the magnet array of being buried underground based on transport trolley road (travel), information such as stop, carrying out automatic guidance and acceleration, deceleration automatically, stop automatically according to the instruction of host CPU 23, and in the transport trolley travels down.Through remote control or advance/operation of stop button also can advance, stop in place arbitrarily.Promptly stop after utilizing various safety devices such as transport trolley protection detecting device to detect danger again.Especially under the situation of utilizing transport trolley protection detecting device, stop action because of automatically forming, so keep certain to stop more than the fixed range at interval with front truck.
In the present invention, as the magnet information of being buried underground at transport trolley road (travel), except the speed of general running, stop etc. the information, for near as the meadow around teeing ground or the match play or transport trolley is indoor waits the charging of control battery to move, promptly pre-its anti-noise takes place in order to prevent to drive the engine starting that electrical generator uses, and also buries the magnet information that the electrical generator of the arrangement of having made up magnet stops to move underground.
In above structure, no matter golf cart of the present invention is in (also comprising descending) under steam, stopping, all monitor the discharge current value and the charging current value of power supply (battery) 11 always, and charging current value, the discharge current value that is detected periodically is stored in memory device 26 as propulsion source with current detection circuit 24.At this, why be conceived to charging current value, discharge current value and be owing to detect for the also stable battery charge of upsets such as alternation in weight, discharge regime and can monitor and prevent battery overcharge.
And, in golf cart travels, host CPU 23 judgements become greatly in the increase of current detection circuit 24 discharge current values, when the charge volume of battery begins to reduce, start the engine of the electrical generator 10a of driving generating/charging unit 10, via charger 10b battery 11 are charged.Then, check charging current values,, engine is stopped, the complete charge action when discharge current value is reduced to set value when following with current detection circuit 24.Each after this manner golf cart begins to travel, and just checks discharge current value with current detection circuit 24, carries out same charging action.
During if golf cart is in and stops, starting drives the engine of the electrical generator 10a of generating/charging unit 10, after determining the engine starting, check charging current value with current detection circuit 24, if charging current value is more than set value, via electrical generator 10a, charger 10b with battery 11 charging, the charging action continue to charging current value become set value following till.Again, check charging current value with current detection circuit 24, if charging current value below set value, then makes engine stop, golf cart is waited for the state that stops.Then with current detection circuit 24 check discharge current value if begin to travel again next time.
In addition, because of monitor the discharge current value and the charging current value of power supply (battery) 11 with current detection circuit 24 always, and charging current value, the discharge current value that is detected periodically be stored in memory device 26, so no matter golf cart under steam, stop, all can grasp the charge condition of battery, after date, positively additional charge when becoming charging.Especially, in golf cart stops, because of starting engine especially with the charge volume of confirming battery, so can the outer noise of amount in order to detect charging current value.
Again, because of the engine of generating/charging unit 10 produces noise in driving, so the place that the linksman in playing golf concentrates on (for example near the meadow around the teeing ground, match play) or to be not suitable for the transport trolley of centrality generation noise indoor, requiring to suppress noise takes place, because of bury underground at the transport trolley road in court the magnet used with speed control different in order to represent the magnet information of engine starting prohibited area in advance, so if golf cart enters this interval, will read this information, can be with the charging action locking of generating/charging unit 10.
And, even detect the magnet information that electrical generator stops to move, in the charging action of power generation assembly being in stop, under the charge capacity that detects battery is in situation below the set value, in order not hinder entry into service again, also can begin the charging action, even battery does not reach full charging in golf cart, if charging current reaches and begins the required set value that travels again, also can make engine stop action not produce more noise.
Structure through the magnet information that adopts the electrical generator only accepting the starting of power generation assembly under steam or stop to stop to move, because of needn't in the control program in the stopping of golf cart, preparing to judge the step whether the magnet information that electrical generator stops to move is arranged, can avoid control system to become complicated.
Again, the charging of battery is except utilizing generating/charging unit 10, and the regenerative brake that travels when utilizing golf cart to brake with motor 13 also can charge a little.So the present invention can not carry out the charging of battery 11 in the transport trolley chamber of golf course, but utilize generating/charging unit 10 T-grounds to charge at any time.Again, generating/charging unit also can utilize small-sized fuel cell.
Secondly, the flow process according to generating/charging control sequence of Fig. 4 illustrates that generating/charging of electric golf cart of the present invention is controlled.In Fig. 4,, judge that at step S1 whether golf cart is to travel by step S0 generating/charging control beginning.
If the situation in travelling then moves to step S2, accept the magnet information that electrical generator stops to move, at step S3, judge the magnet information that electrical generator stops to move that whether detects.If detect the magnet information that electrical generator stops to move, make electrical generator stop to move till the instruction that has electrical generator to restart at step S4.
If at step S3, do not detect the magnet information that electrical generator stops to move, step S5 in the back then judges the size of discharge current (discharge rate).If the situation that discharge current is little, it is little and needn't additional charge then to be judged as discharge rate, then, and the judgement of reignition size of current similarly.If the situation that discharge current is big, it is big then to be judged as discharge rate, moves to step S6, and starter generator drives the engine of usefulness.
Then, at step S7, judge whether engine has started.If engine unstart (NG) then moves to step S6 again, attempt the engine that starter generator drives usefulness.If judge that engine has started, then move to step S8, judge the size of discharge current (discharge rate).
If discharge current is big, judge that then discharge rate is still big, the judgement of same reignition size of current.If discharge current is little, it is little and additional charge more then, moves to step S9 then 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.
If at step S1, the judgement golf cart then moves to step S10 in being in and stopping, and starter generator drives the engine of usefulness.At step S11, judge whether engine has started.If engine unstart (NG) then moves to step S10 again, attempt the engine that starter generator drives usefulness.If judge that engine has started, then move to next step S12, judge the size of charging current (charge volume).
Under the big situation of charging current, judge that then charge volume is still little, similarly the judgement of recharge size of current.Under the little situation of charging current, it is big and additional charge more then, moves to step S13 then to be judged as charge volume, and the engine that generator drive is used stops.
After the engine that generator drive is used stops, judging that at step S14 whether golf cart is to travel.If the judgement golf cart then repeats same acts of determination in being in and stopping.In the judgement of step S14,, then move to step S2, repeat the master mode in above-mentioned the travelling if golf cart begins to have travelled.
Secondly, describe according to the flow process of generating/charging control sequence of other embodiment according to Fig. 5.
In Fig. 5,, judge that at step S1 whether golf cart is to travel by step S0 generating/charging control beginning.
If the situation in travelling moves to step S2, accept the magnet information that electrical generator stops to move, at step S3, judge the magnet information that electrical generator stops to move that whether detects.If detect the magnet information that electrical generator stops to move, till the instruction that has electrical generator to restart, make electrical generator stop action at step S4.
If at step S3, do not detect the magnet information that electrical generator stops to move, at next step S5, accept the magnet information that electrical generator output reduces, judge whether detect the magnet information that electrical generator output reduces at step S6.If detect the magnet information that electrical generator output reduces, then at step S8, the electric energy generated that is set as electrical generator becomes 50%, do not export the magnet information that reduces at step S6 if detect electrical generator, then the electric energy generated that is set as electrical generator at step S7 is 100%, at step S9, judge the size of discharge current (discharge rate).If discharge current is little, it is little and needn't additional charge then to be judged as discharge rate, then, and the judgement of reignition size of current similarly.If discharge current is big, it is big then to be judged as discharge rate, moves to step S10, and starting drives the engine that electrical generator is used.
Then, at step S11, judge whether engine has started.If engine unstart (NG) then moves to step S10 again, attempt starting and drive the engine that generator drive is used.If judge that engine has started, then move to next step S12, judge the size of discharge current (discharge rate).
If discharge current is big, judge that then discharge rate is still big, the judgement of reignition size of current similarly.If discharge current is little, it is little and additional charge more then, moves to step S13 then 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.
If at step S1, the judgement golf cart then moves to step S14 in being in and stopping, and starter generator drives the engine of usefulness.At step S15, judge whether engine has started.If engine unstart (NG) then moves to step S14 again, attempt the engine that starter generator drives usefulness.If judge that engine has started, then move to next step S16, judge the size of charging current (charge volume).
If charging current is big, judge that then charge volume is still little, similarly the judgement of recharge size of current.If charging current is little, it is big and additional charge more then, moves to step S17 then to be judged as charge volume, and the engine that generator drive is used stops.
After the engine that generator drive is used stops, judging that at step S18 whether golf cart is to travel.If the judgement golf cart then repeats same acts of determination in being in and stopping.In the judgement of step S18,, then move to step S2, repeat the master mode in above-mentioned the travelling if golf cart begins to have travelled.
In the present embodiment, represented that controlling quantity with electrical generator is divided into 50% and 100% two kind situation, but also can be subdivided into 3 sections, 4 sections certainly controls, and according to the place control electric energy generated of golf course, adjusts noise again.Again, through electrical generator being stopped and making it with actions such as idling conditions, the control in the time of can not needing to start has available simple control to increase the effect of electric energy generated.
As noted above, golf cart of the present invention, be loaded into the court of generating/charging unit in playing golf that constitutes by power generation assembly and the charging unit charging voluntarily at any time of golf cart through utilization, can prevent to play golf for a long time or special can't the travelling that the power supply capacity deficiency causes when turning round of travelling, can omit the high-capacity charging unit of transport trolley chamber again, and, produce noise in unaccommodated place so can prevent the engine of electrical generator because of action according to the magnet information Control power generation assembly of burying underground at travel.
Again, for the linksman who requires concentrated force, near the engine running sound of the power generation assembly the meadow that is intended to around teeing ground or the match play very, electric golf cart is being concealed in the transport trolley chamber again, when many golf carts begin to carry out the charging of battery, noise is very big, so if detect the magnet information that electrical generator stops or electrical generator output reduces, can prevent or reduce the engine noises of power generation assembly.
Again, even detect during magnet information that electrical generator stops to move is in the charging action of power generation assembly to stop, under the charge capacity that detects battery is situation below the set value, in order not hinder entry into service again in golf cart, also begin the charging action, even battery does not reach full charging, if charging current reaches and begins the required set value that travels again, also can make engine stop action, can prevent from further to produce engine noises.
