    20 25 30 533 982 tors, drivable vehicles and there resp. vehicles must have a power regulating control circuit, for the creation of a selected and required propulsive power and / or a speed adjustment and / or control.
    The invention is intended to be able to be applied to road construction in the form of public and private roads and along its road sections, but can also be used in industrial facilities, with different requirements for power needs and energy needs.
    The invention intends to e.g. at the same time as an energy charge of the battery set from the external energy source to supply the power and energy that will be required for a selected, for the vehicle driving upwards and over an upwardly sloping road section adapted, power requirements.
    More particularly, the present invention provides such a system where an untracked vehicle, such as a truck, during its driving along selected road sections with its vehicle-assigned battery array can be supplied with a supplementary energy, such as from the external energy source or from a vehicle-related energy source, such as a diesel generator.
    In this regard, the present invention proposes a "first" vehicle-related energy source, such as a diesel generator, a "second" vehicle-related energy source, such as a battery set, and a "third" from the vehicle separate and external energy source, such as live electrical or two conductors. tracks in successive road sections, and where the conductors for a selected road section are electrically isolated from the corresponding conductor for an adjacent (previous or subsequent) road section.
    The present invention is based on two or two conductors being built into a track or in each track in its own road section and where the track (not the conductors) extends continuously from road section to road section.
    The voltage assigned to these voltage-conducting conductors can be an AC voltage (with a vehicle-related rectifier) or a DC voltage. When selecting a direct voltage, one conductor can be positive while the other conductor can be negative and an additional conductor assigned ground potential or zero potential, whereby the vehicle can be operated with double the voltage value.
    In the case of alternating voltage to the conductors for the road sections, this can advantageously be arranged in opposite phase and symmetrically around a ground potential or zero potential.
    The motor intended for driving the vehicle may be of a direct current type or of an alternating current type, in which case the motor must be connected to an inverter.
    BACKGROUND OF THE INVENTION Methods, arrangements and constructions, related to the above-mentioned technical field and nature, are previously known in a number of different embodiments.
    In the case of electrically powered vehicles, these can advantageously be categorized as "rail-bound vehicles" or as "non-rail-bound vehicles".
    “Rail-bound vehicles” are driven along their road section and road sections of parallel rails laid in the road section or exposed via slippers, which guide the vehicle's fixed pairs of wheels.
    "Non-rail vehicles" are driven along their road section and road sections over a drivable road and are driven along the road sections via a control equipment belonging to the vehicle.
    The present invention is based on and is intended to be utilized in the latter category and technique, and is primarily intended to be able to be applied to heavy goods vehicles, with or without coupled trailers, where it is known, by the patent publication US-4,129 203-A, a vehicle-related arrangement for causing the vehicle underlying contact springs, up and down and laterally, for mechanical and electrical interaction with or out of interaction with the non-insulated surface sections of the energized electrical conductors (14) associated with the road section.
    Here, the use of an insulator (16) within a channel (18) which supports the conductors in the form of rails (14) is indicated. A cover plate (20) formed with a slot (12) is removably attached to the upper and opposite wall portions of the channel (18), this cover plate (20) being adjusted to a plane adjoining the upper part of the road section. surface (22).
    Figures 2 and 3 of the cited patent publication describe a vehicle-related table (98) and to which table an arm (10) is rotatably attached (94, 96, 99). Sensors (30) assigned to the table (98) generate signals which, with respect to phase position and size, indicate the direction and distance from a axis of rotation (99) to the slot (12) in the cover plate (20), which is based on changes in a generated magnetic field. Via a designated mechanism (31), the table (98) and the arm (10) can be driven by a motor (32) between predetermined limits and limit switches (40, 41) located there.
    From the patent publication WO 93/10995-A a system is previously known for having electrically drivable vehicles driven along a stretch of road and its road sections.
    Figure 9, in the patent publication stated here, clarifies the system's basic structure.
    It is indicated here that the road section (14) and its road sections are provided with electrically conductive road sections (300a - 300f), where a road section can be considered to correspond to a road section.
    The vehicles (310) have an electric motor (320) and two (312, 314) or three (312, 312 'and 314) underlying contact springs, adapted for a mechanical and electrical contact with the electrically conductive conductors, the length of which is adapted to correspond a selected length (identically equal lengths) for utilized road sections or sections.
    The electrically conductive conductors within the road sections (300a - 300f) are placed one after the other with a medium-oriented free space (302a - 302e), in order to prevent a short circuit via trailing contact springs (312, 3122 314).
    Every other road section (300b, 300d, 300f) is here connected continuously to a reference voltage (earth potential) while the other road sections (300a, 300c and 300e) are either directly connectable to a DC voltage source (440) or via a 533 982 coupling means (304a, 304b, 304c) connectable to any suitable electrical energy source (308), when a vehicle is nearby.
    When an embodiment with three contact springs is used, the distance between them must be chosen so that two or three contacts are always in an electrical contact with two opposite poles of road section and that neither of the two contacts can short-circuit the free space (302a - 302e) between two nearby sections.
    The system here requires for its function specially designed vehicles (310), where a selected distance between front (314) and rear (312, 312 ') contacts must be identically equal and further selected slightly longer than the equal lengths of the road sections (300b, 300d).
    Thus, specially designed vehicles with front and rear contacts are required and where each of the used road sections (300a - 300f) must be selected with equal lengths and oriented one after the other in the direction of travel of the vehicle with equally free and intermediate spaces (302a - 302e) .
    The patent publication otherwise indicates the presence of a single live conductor or rail within a road section (p. 5, lines 11-13), and that a vehicle must be able to apply voltage to a road section in front (p. 5, lines 19-21; p. 6, lines 7-10; p. 8, lines 28-32).
    It is further instructed that voltage-adjustable rails (16) must be able to be provided with side-by-side drainage grooves (page 9, rows 1-4).
    An absence (or presence) of an activation signal must be able to affect a control unit (see) (p. P, lines 23-27).
    The required distance between vehicle-related contacts is stated on the side. 10, line, 17-20 and an utilization of activity-initiating radio signals is proposed on p. 11, lines 2-4 and p. 14, lines 1-16. 10 15 20 25 30 533 582 Further proposed, on p. 15, lines 21-23 and p. 16, lines 1-15, an utilization of a Hall element (240) and its connection to an amplifier (246). Alternatives to this are further illustrated on page 17, lines 3-9.
    It is also known to electrically drive a vehicle along a stretch of road by means of an inductive energy transfer effective between a vehicle and an underlying road section.
    As an example of this prior art, reference is made to the contents of U.S. Patent Nos. 3,914,562-A and 4,007,817-A.

    Thus, Figure 1A shows a vehicle 1 driving, electrically and by one or more of your batteries or a set of batteries, driving along a stretch of road 2 and its road sections 2a1 and 2a1 '.
    The vehicle 1 here consists externally of an "A-Ford", but this is here converted to a battery-powered vehicle, with an access to an external energy source, designated "s1", "lll".
    The vehicle 1 according to the invention shall then comprise a control equipment (not shown), so that a driver "F" (not shown) can drive and steer the vehicle 1 along said road section 2 and its road section 2a1. The vehicle 1 could also comprise a gearbox and other parts and details required for the operation of the vehicle, but as these parts are well known to a person skilled in the art, these will not be described in detail.
    However, an electrically driven vehicle 1 does not need a gearbox as a speed control and a power take-off can take place via known electrical and electronic circuits.
    Figure 1B shows, in the same way as in the fi clock 1A, an electrically propulsive truck 1b with coupled trailers 1c along the road section 2, 2a and its road section 2a1. Figure 15C now clearly shows two vehicle-related energy sources, designated "l" and "ll", a "first" in the form of a diesel generator, a "second" in the form of a battery or a battery set. and a “third” energy source “lll” in the form of a vehicle external energy source, here formed as, via coupling means or switches, energizable parallel conductors or rails, recessed in grooves and a cavity in the carriageway or road section 2.
    These are in Fig. 1C coordinated to a vehicle-related control circuit 100, which, depending on a power supplied to an electric drive motor 5, allows all or a combination of the power supply energy sources "1", "11" and "lll". The power control is illustrated here as an accelerator pedal 100a, whose up and down movement is connected to a maneuvering circuit "R2" within the control circuit 100, which in turn comprises a circulating "power", power and energy between the energy sources.
    Figure 1D illustrates in a P / t (power / time) diagram how a full power or a reduced power can be distributed and transmitted for the passage of the vehicle along a different road section 2a of a carriageway or road section 2 by means of the circuit ". R1 "and the control circuit" R2 ".

    Between the times tf, - te, a reduced power output from the energy sources “ll” and “lll” is illustrated. l "," B ". 10 15 20 25 30 533 982 16 The invention is based on the battery set "B" and the second energy source "II" primarily, via the distribution circuit "R1", supplying the motor 5 and for this purpose it is required that the battery set "B" has stored an energy that can drive the motor 5 at full power.
    Battery set “I |”; "B" shall primarily be charged via the energy source "lll"; "S1" and in the alternative is maintained or charged via the energy source "l".
    The energy from the energy sources "l" and "lll" can be selected to 5 - 30% of the energy assigned to the energy source "ll"; such as about 25%.
    The supply voltage to the motor 5 can be selected to +40O VDC and -400 VDC, i.e. voltage value 800 VDC.
    The system “S” proposed according to the invention shall then primarily comprise: “a” one or fl era, via each electric motor 5 or motors, electrically drivable vehicles 1, 1b and where resp. vehicles have a power distributing and / or regulating control circuit “Rt” within the control circuit 100, for creating a required power and / or a speed control via the control circuit “R2” and the accelerator pedal 100a.
    The required output power shall be provided primarily by the vehicle external energy source "ll"; "B" and which is to be subjected to a secondary charge from the energy source "lll"; "S1". The road section 2 is shown subdivided into road sections 2a (2a1, 2a2, 2a3; 2a1 ', 2a2' and 2a3 '), where each should advantageously be assigned an external energy source "lll", illustrated here as a number of electrical stations "s1".
    The vehicle external third energy source "lll"; "S1" and / or the vehicle's first energy source "l"; "G" can be used one or both, to thereby additionally charge the vehicle's battery set “ll”; ”B” during an adapted time sequence of power take-offs from this battery set. Also within the scope of the invention is the possibility that in addition to driving the vehicle 1 via the battery sets "ll"; "B" and during a supplementary charge of the battery set "ll"; "B" along the road sections and the stationary electrical stations "sl" or the energy source "lll" can, for the vehicle 1's travel over the road section 2a1, a required additional power and energy is supplied via the vehicle-associated energy source " l ";" G ".
    Figure 2 shows in principle an electrical / mechanical coupling arrangement "K" related to a vehicle 1, (1 b) with a schematically shown control equipment 10, for guiding a vehicle belonging to pantograph 4 towards and to an electrical contact with pairable live wires. , in the form of rails 4a, 4b, for a possible joint parallel operation of an electric motor 5, from the battery set "11"; "B" and / or from the stationary station "lll"; "s1", and / or from the diesel generator "G".
    The pantograph 4 is here related to a carrier 6, which is vertically arranged up and down via a first electric auxiliary motor 7 and laterally is arranged movably back and forth via a second electric auxiliary motor 8.
    The means and the control of the auxiliary motors 7, 8 required for this movement by means of sensors are not shown in detail but are in principle previously known and obvious to a person skilled in the art.
    The auxiliary motor 7 and the auxiliary motor 8 can both be actuated in a reciprocating motion, where a first motion is activated via a first signal on a first conductor 7a and 7, respectively. a first signal on a first conductor 8a, while a second (opposite) movement is activated via a second signal on the conductor 7a resp. 8a, while the instantaneous setting positions of the motors 7, 8 and the carrier 6 are evaluated by one or more of the sensors (not shown) and indicated via an generated signal on a second line or conductor 7b resp. 8b.
    These signals on the first conductors 7a, 8a are generated in a central unit or control circuit 100 with a control equipment 10 and signals on the second conductors 7b and 8b are generated within the same central unit 100, using position sensors (not shown).
    The central unit 100 with the control equipment 10 is a complex unit, which i.a. via a sensor 16 should be able to sense the presence and orientation of conductors 4a, 4b and then lower the pantograph 4, via the auxiliary motor 7, to an electrical contact with these conductors 4a, 4b, which is illustrated here as live or vice versa. 10 15 20 25 30 533 982 Via a connection 10a to the central unit 100 and its control circuit "R2" the power to be supplied via the control circuit "R1" to the engine 5 is regulated. For this purpose it is required that the control circuit "R1" is directly controlled by an accelerator pedal 100a (figure 1C) in order to supply the required power to the motor 5 via the control circuit "R2".
    In the position shown, the current collectors 4 conduct current and voltage from the energy source "| II" to a power and energy-distributing control circuit "R1". This or another control circuit "R2" senses via the central unit 100 the power requirement for the motor 5 and the loudspeaker primarily supplies the motor 5 with the power it needs according to the input signal on the connection or line 10a and generated output signal on the connection or line 10b and thus the stationary system "s1", "lll" are loaded and supplement the power and energy requirements via the battery set "ll", A parallel connection of the vehicle externally removed power "lll", "s1" and the vehicle internally generated power "G" and / or "| l", "B" can here be realized via the control circuits "R1" and "R2".
    Via line 10a information to the central unit 100 is input about a desired speed and associated power for the vehicle 1 and via internal circuits (not shown) and the function "R2"; "10" is influenced via line 10b the control circuit "R1".
    Figure 3 shows, in an end view, a vehicle 1 (1b) with its downwardly directed pantographs 4 in a mechanical and electrical interaction with the two live conductors or rails 4a, 4b assigned to the road section 2a1 'and a ground connection 4c.
    Figure 4 shows an electrical connection arrangement "K1" where road sections on road sections 2a1, 2a2 and 2a3 respectively 2a1 *, 2a2 'and 2a3' with their station after station "s1", "S2". "s3" resp. "S1" s2 '"and" s3' ", can be activated and energized from one and the same superior charging source" | l | ", 42, via switches or coupling means 43a, 44a, and 45a for one road section 2a and 43a ' , 44a 'and 45a' for the opposite road section 2b, as a vehicle 1 will pass along the electrically separated, but longitudinally coordinated tracks, road sections 2a, 2b. 10 15 20 25 30 533 982 19 This requires a number of switches or switching means (switches) for a connection and disconnection of the stations "s1", "s2", where this connection and disconnection can take place via stationary related to the road section. sensors (not shown).
    The present invention and its detection arrangement will now be described in more detail with reference to Figures 5 to 11.
    Thus shown in Fig. 5 of an arrangement, where side-by-side said grooves 51, 52 in the carriageway 2a1 or in the duct 30 are arranged one or more electrical conductors L1, L2, through which are arranged to pass a direct current, to generate a magnetic field and / or permanently magnetized magnets are inserted in place of these conductors L1, L2, to generate said magnetic fields.
    A coil Sp1 related to the vehicle 1 is adapted to, by its relative movement over the tracks 51, 52, cause the magnetic field "B" to be detected by variation and via a control equipment 10 to influence the pantograph 4 via associated auxiliary motors 7, (8), for a interaction with the groove and the electrically energizable conductors 4a, 4b inserted in the bottoms of the grooves 51, 52.
    The distance "h" between the conductors L1, L2 and / or the magnets related to the carriageway 2a1 and the vehicle-related coil Sp1 is adapted to less than 15 cm, such as between 10 and 1 cm.
    The reference numeral "d" indicates a selected distance between the conductors L1, L2 and the reference numerals "-x" and "+ x" are intended to indicate the distance that the coil Sp1 occupies from an oentral plane "0" of the grooves 51 and 52 or the conductors L1, L2 and to be able to determine the orientation of the grooves 51 and 52 and to be able to lower the contact means 4 to a cooperation with the rails 4a, 4b, alternatively 4c.
    Figure 6 then illustrates the distance dependence of the magnetic field ("-x"; "+ x") variation "B" for three different heights where it appears that the coil Sp1 indicates a minimum at the central plane. The conductors L1 and L2 are supplied with equal currents and with opposite directions, which gives the curve shapes according to Figure 6. Figure 7 illustrates that said coil consists of two coils Sp1, Sp2, oriented one after the other across the direction of travel of the vehicle 1.
    The reference numeral and "+ x" is intended to indicate the distance that the coils Sp1, Sp2 occupy from a central plane "0" of the grooves 51 and 52 or the conductors L1, L2 and to be able to determine the orientation of the grooves 51 and 52 and to be able to lower the contact means 4 for a cooperation with the rails 4a, 4b, alternatively 4c.
    Figure 8 then illustrates the distance dependence of the magnetic field ("-x"; "+ x") variation "B" for three different heights "h", where it appears that the coils Sp1, Sp2 indicate a maximum at the central plane Leaders L1 and L2 is fed with equal currents and with opposite directions, which gives the curve shapes according to Figure 8 when the coils Sp1 and Sp2 are connected.
    The control equipment 10 is adapted, when the magnetic field has increased and begins to decrease, according to Figure 6, to cause the auxiliary motors 7, (8) to lower the pantograph 4 into contact with live conductors 4a, 4b.
    The control equipment 10 is further adapted, when the magnetic field "B" for the coils Sp1 and Sp2 has increased and begins to decrease towards "0", according to fi gur 8, to calculate or wait for a maximized magnetic field "B" and influence the auxiliary motors 7, (8) to lower the pantograph 4 to contact with live conductors 4a, 4b.
    The control equipment 10 is also adapted to be able to distinguish via a circuit a minimum value or a maximum value, valid for a false identification of a track from false values.
    The two coils Sp1, Sp2 are oriented at the same vertical distance “h” from parallel electrical conductors or magnets, related to the tracks 51, 52 and / or the road section 2a1.
    The principle of the invention is to relate to the insight that by laying cables L1, L2 in the road section 2a1, a detector 16 next to the pantograph 4 can detect magnetic fields from the coil Sp1 in Figure 5 or from the coils Sp1; Sp2 in figure 2 and thereby locate where the tracks 51, 52 are located. 10 15 20 25 30 533 982 21 To avoid mistakes, use a frequency that does not normally occur. It is important to avoid mains frequency and harmonics to the mains frequency. In this way, the detectors can be made very selective by filtering narrow-band with a high gain.
    Figure 6 thus intends to illustrate the variations of the magnetic fields at three different distances and height "h" from the live conductors L1, L2, with "h" selected to 10 cm, 3 cm and 1 cm, with increasing B-value.
    There may be difficulties in determining from this data when the contact 4 is to be lowered into the grooves 51, 52. It is particularly troublesome that the field "B" increases and then decreases from to "0" and therefore increases by "+ x". at a minimized field strength the contacts 4 must be lowered.
    By inserting two coils Sp1, Sp2, according to Figure 7, a more sophisticated assessment can be made.
    Figure 8 is intended to illustrate the subtracted sum of the magnetic fields in two coils Sp1, Sp2, with the same distance from each other as the tracks 51 and 51, respectively. 52 width in road section 2a1.
    Maximum magnetic field "B" is obtained when the contact 4 and the coils Sp1, Sp2 are in the middle of the grooves 51; 52. This increases the safety of lowering the contacts 4 at the right time.
    However, in some cases it can still be difficult to find the absolute maximum value, as it cannot be ignored that there may be local maximum values at the wrong place.
    The following function is studied; f (x, h) = | B1 (x, h) + B2 (x, h) | / | B (x, h) | Where: B1 is the field in detection coil Sp1, as a function of distance from the track 51 and height above the road section 2a1; B2 is the field in detection coil Sp2, as a function of distance from the track 51 and height above the road section 2a1; and B is the sum of the two fields; For example, the curve shape according to Figure 8 can be transformed into a curve shape according to Figure 9, where the coils Sp1 and Sp2 are connected in series.
    Figure 9 then shows the function at 10 cm, 3 cm and 1 cm height "h" over the carriageway 2a1 and gives distinct values "B2" during a reference (ref).
    As can be seen, the function gives a distinctly low value in the vicinity of the value "0" and the track 51 resp. 52. This can be used to delete the local maximum values.
    Form a new function according to: f1 (x, h) = 1 if f (x, h) <uref f1 (x, h) = 0 If f (x, h)> uref.
    According to Figure 10, this gives a high value close to the track 51 resp. 52, but “0” further away on the x-scale from the “0” point.
    The value "uref" is selected so that the value becomes "0" at the local maximum values. However, the value "uref" can be selected within a fairly wide range.
    The function f1 (x, h) is multiplied by the B-fields, from the two coils Sp1, Sp2 below the “ureF value in fi gur 9 to form the graph according to figure 10.
    As can be seen, a distinct signal is obtained very close to the center of the tracks 51 resp. 52.
    The control must now make sure to look up the maximum value and there lower the contact 4. Then the track 51 resp. 52 one to lie exactly right without the risk of confusion with false values.
    Figure 11 thus intends to illustrate in more detail in a perspective view the embodiment according to Figure 7. It will be appreciated that Figure 11, in a slightly modified embodiment, may be used in the embodiment according to Figure 5.
    Paired pantographs 42a, 42b for a second track 52 years immediately oriented over the track 52.
    The bottom of the groove 51 carries the energizable or energized conductor 4a while the bottom of the groove 52 supports the conductor 4b.
    According to the instructions of the invention and with a reference to the embodiment according to Figure 7, the presence of two coils Sp1 and Sp2 is indicated, which are fixedly related to the current collectors 41a, 41b and 42a, 42b and shall follow horizontally in the horizontal movement of the pantographs to detect the presence of and the instantaneous position of the tracks 51 and 52 fixedly related to the carriageway 2a1.
    The sensed signals from the coils Sp1 and Sp2, which are dependent on the instantaneous magnetic field from the conductors L1 and L2, are fed to the control equipment 10 as input signals.
    Via a calculation circuit 10a1 and taking into account stored criteria in memories, an output signal is generated to influence the auxiliary motor 7 to lower the pantographs 41a, 41b and 42a, 42b down towards and for an electrical interaction with the conductors 4a, 4b.
    The calculation circuit 10a1 can also generate an output signal for influencing the auxiliary motor 8.
    In the memory 10a2 are stored magnetic fields depending on the horizontal distance from the track, in the memory 10a3 is stored the vertical distance "h" and in the memory 10a4 other relevant criteria.
    The invention is of course not limited to the embodiment given above as an example, but may undergo modifications within the scope of the inventive concept illustrated in the appended claims. 10 15 20 25 30 533 982 24 In particular, it should be noted that each displayed unit and / or circuit can be combined with any other displayed unit and / or circuit within the framework in order to be able to achieve the desired technical function.
