    10 15 20 25 30 its road sections and "b" one or more, via their respective electric motor or a number of motors, drivable vehicles and where resp. vehicles shall 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 intends to be able to be applied to road sections in the form of public and private roads and along its road sections. , but can also be used in industrial plants, with different requirements for power needs and energy needs.
    The invention intends that i.a. 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 a non-tracked vehicle, such as a truck, during its driving along selected road sections with its vehicle-assigned battery set 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" vehicle-separated and external energy source, such as two or more conductive electrical 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 more conductors being built into a track or in their respective tracks in their road section and where the track (not the conductors) extends continuously from road section to road section. 10 15 20 25 30 b) 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 earth potential or 0 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 an earth potential or O-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 "track-bound vehicles" or as "non-track-bound vehicles".
    "Rail-bound vehicles" are driven along their road section and road sections of parallel rails embedded in the road section or via slippers, which guide the vehicle's fixed wheel pairs. the vehicle's control equipment.
    The present invention is based on and is intended to be utilized in the latter category and technology, 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 a mechanical and electrical interaction with or out of an 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), where this cover plate (20) is adjusted to a plane adjoining the upper surface (22) of the road section.
    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 principled 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 to a selected length (identical equal lengths) for used road sections or sections.
    The electrically conductive conductors within the road sections (300a - 300f) are arranged one after the other with a medium-oriented free space (302a - 302e), in order to prevent a short circuit via trailing contact springs (312, 312 ', 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 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 polarity road sections and that neither of the two contacts can be short-circuited the free space (302a - 302e) between two adjacent 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 should be able to apply voltage to a preceding road section (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 (p. 9, rows 1-4).
    An absence (or presence) of an activation signal must be able to affect a control unit (38) (page 8, 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 Furthermore, it is 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 road section by means of an inductive energy transfer, acting between a vehicle and an underlying road section.
    As an example of this prior art, reference is made to the contents of patent publications US-3 914 562-A and US-4 007 817-A.

    It should then be emphasized at the outset that in the following description of presently proposed embodiments, which exhibit the significant features associated with the invention and which is clarified by the figures shown in the following drawings, we have selected terms and a particular terminology for that purpose. to thereby in the first instance make clear the very idea of the invention.
    In this context, however, it should be borne in mind that the terms chosen here are not to be construed as limiting only the terms used and chosen here, but it should be understood that each term thus chosen should be interpreted so that it may also cover all technical equivalents, which functions in the same or substantially the same way, in order to be able to achieve the same or substantially the same intention and / or technical effect.
    With reference to the appended figures, the basic preconditions for the present invention and where the significant peculiarities associated with the invention have been concretized are thus shown schematically and in detail, through the embodiments now proposed and described in more detail below.
    Thus, Figure 1A shows a vehicle 1 driving, electrically and by one or more batteries or a set of batteries, propelled along a road section 2 and its road sections 2a1 and 2a1 "adapted system. The vehicle 1 here is externally constituted by a" T-Ford ", but this is here converted to a battery-powered vehicle, with a continuous access to an external, a third, energy source, here designated "s1", "lll".
    The vehicle 1 according to the invention shall then comprise a steering arrangement 3 or a steering 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 figure 1A, an electrically propulsive truck 1b, with coupled trailers 1c along the road section 2, 2a and its associated road section 2a1.
    Figure 1C 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's external energy source, here formed as, via coupling means or switches, voltage-setting parallel conductors or rails, recessed in grooves and a cavity along the roadway or the entire road section 2.
    These are in Figure 1C coordinated to a vehicle-related control circuit 100, which, depending on a supplied power to an electric drive motor 5, allows to select all or a combination of the power-supplying energy sources "II" resp. "lll". The power control is illustrated here as an accelerator pedal 100a, whose movement up and down is connected to a maneuvering circuit "R2" within the control circuit 100, which in turn comprises a circulating "power and energy between the energy sources" R1 ".
    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 ti - t; illustrates in principle how a full power take-off from the three energy sources “ll” and “lll” can be realized, with the power take-off from the energy source “l” illustrated at the top, the power take-off from the energy source “ll” illustrated below (dashed lines) and the power take-off for the energy source "lll" illustrated below.
    Between the times t3 - t., A reduced power output from the energy sources “l” and “ll” is illustrated in principle, while the energy source “lll” is illustrated here disconnected.10 15 20 25 30 Between the times t5 - t6 is illustrated in principle a reduced power consumption from the energy sources "ll" and "lll" _ During this time duration tf, - ts full power can be obtained from the energy source "ll" and a small excess can be allowed to charge the battery set "ll". The invention is based on the battery set " B ”and the second energy source“ ll ”shall primarily, via the distribution circuit“ R1 ”, supply the motor 5 and for this purpose it is required that the battery set“ B ”has stored an energy which can drive the motor 5 at full power.
    Battery set "ll"; "B" shall primarily be charged via the energy source "lll"; "Si" and alternatively maintained or charged via the energy source 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 +400 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 more, via separate electric motors 5 or motors, electrically drivable vehicles 1, 1b and where resp. vehicles have a power distribution and / or regulating control circuit "R1" 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 ”. lO 15 20 25 30 16 The vehicle external third energy source "lll"; "s1" and / or the vehicle-associated first energy source "l"; "G" can be used one or both, to thereby additionally charge the vehicle's battery set "ll"; during a custom time sequence of power outputs from this battery pack. Within the scope of the invention also falls the possibility that in addition to driving the vehicle 1 via the battery sets “ll”; "B" and during an additional 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 driving over the road section 2a1, a required additional power and energy is supplied via the vehicle-associated energy source "l"; Figure 2 shows in principle a electrical / mechanical coupling arrangement "K" related to a vehicle 1, (1b) 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 "ll"; "B" and / or from the stationary station "| ll"; "s1", and / or from the diesel generator The pantograph 4 is here related to a carrier 6, which in height is movably arranged up and down via a first electric auxiliary motor 7 and laterally is movably arranged 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 sensors (not shown) and indicated via an generated signal on a second line 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.
    Via a connection 10a to the central unit 100 and its control circuit "R2", the power which is supplied to the motor 5 via the circuit distributing the energy source "R1" 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 engine 5 via the control circuit "R2".
    In the position shown, the current collectors 4 allow current and voltage to be conducted from the energy source "lll" 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 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" shall be 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 “ll”, “B” can be realized here 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 pantograph 4 in a mechanical and electrical interaction with the two live conductors or rails 4a, 4b associated with the road section 2a1 'and a ground connection 4c. 10 15 20 25 30 18 Figure 4 shows an electrical connection arrangement "K1" where road sections on road sections 2a1, 2a2 and 2a3 resp. 2a1 ', 2a2' and 2a3 'with their station after station "s1", "s2", "s3" respectively. "S1" s2 and "s3 '", can be activated and energized from one and the same superior charging cable "lll", 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 road sections 2a, 2b.
    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 sensors (not shown) related to the road section.
    The present invention and its detection arrangement will now be described in more detail with reference to Figures 5 to 8.
    Thus shown in Figure 5 on an arrangement in which one, two or more, a magnetically disturbed field sensing coils Sp1, Sp2 are vehicle-related, and in which said grooves 51, 52 are formed in a channel consisting of a metal or rail 30 ', the upper portions 30a 'are intended to connect to the road section 2a1 of the road section.
    A third coil Sp3 is adapted to enclose the coils Sp1 and Sp2 and allow a magnetic field to be generated.
    The coils Sp1, Sp2 related to the vehicle 1 are adapted to sense the magnetic field changed by the passage over the rail 30 "and at a" 0 "value via a control equipment 10 actuate the current collector 4, via associated auxiliary motors 7, (8), for a interaction with the groove or grooves and the electrically energizable conductors 4a, 4b inserted in the grooves 51, 52.
    The distance “h” between the metal parts of the ducting related to the carriageway 2a1 and the vehicle-related coils Sp1 can be adapted to less than 15 cm, such as between 10 and 1 cm. The sensing coils Sp1, Sp2, are oriented one after the other across the direction of travel of the vehicle and a third coil Sp3, through which a current (an alternating current) is to pass to generate a magnetic field, which is to be successively disturbed by the rail 30 ". .
    The control equipment 10 is adapted, when the magnetic field from the two opposite coils Sp1 and Sp2 has decreased and begins to increase, to cause the auxiliary motors 7, (8) to lower the current collector 4 to contact with live conductors 4a. , 4b.
    The control equipment 10 is also adapted to separate a min value or a max value and / or an "O" value, valid for an identification of a false trace from false values.
    The two coils Sp1, Sp2 (but also coil Sp3) are oriented and are intended to be displaced "v" relative to the grooves 51, 52 and / or the road section 2a1.
    The principle of the invention is to relate to the insight that by placing rail 30 'in the road section 2a1, a detector 16 next to the current collector 4 can detect a changed magnetic field via the coils Sp1; Sp2 and thereby at a "0" pass for generated voltage locate where tracks 51, 52 are located.
    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. according to Figure 5.
    It will be appreciated that Figure 6 in a slightly modified embodiment may be used in other embodiments with one or more coils Sp1, Sp2 and / or Sp3. One, two or more, magnetic field generated by an electric current "1" takes place via the coil Sp3, via coils Sp1, Sp2, a variation of the magnetic field is sensed when it is disturbed by the ducting 30 'and all coils are vehicle related.
    The said grooves 51, 52 are formed in a rail 30 'consisting of a metal, the upper portions 30a' of which are intended to connect to the carriageway of the road section 2a1.
    The rail 30 'is formed from a steel material or the like and with internal insulation and conductors 4a, 4b.
    Figure 6 is intended to illustrate a position where paired pantographs 41a, 41b for a first track 51 are oriented over the track 51.
    Paired pantographs 42a, 42b for a second track 52 are oriented immediately across 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 reference to the embodiment according to Figure 5, the presence of two magnetic field change sensing 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 magnetic field is generated by a third coil Sp3.
    The sensed signals from the coils Sp1 and Sp2, which are dependent on the instantaneous magnetic field, 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 resp. 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 (-x; + x) from the grooves 51, 52, in the memory 10a3 are stored the vertical distance "h" and in the memory 10a4 other relevant criteria.
    With a reference to Figure 7, an effect / time diagram, valid between times t7 and ta, is illustrated, when the vehicle 1 is to pass the road sections 2a1, 2a2 and 2a3 with different power requirements.
    Thus, the curve “P1” illustrates the temporal distribution of the required variable power to the vehicle 1's motor 5 in kW, the customer “P2” intends to illustrate the power level (here chosen constant t) from the third energy source III; "S1", the curve "P3" is intended to illustrate the varying effect that the battery set ll; “B” stands for and the curve “P4” is intended to illustrate the temperable effect as the first energy source l; "G" can generate.
    Figure 8 illustrates the negative sum voltage from the coils Sp1 - Sp2 in a voltage / distance graph as these coils are shifted from "-x" past "O" - value and along "+ x".
    At the "0" value for the voltage "V", the pantograph 4 must be activated.
    The invention thus directs to be connected to a generator the coil Sp3, which provides a high-frequency current through the coil. A high frequency magnetic field is generated and this passes through the two coils Sp1 and Sp2. In the coils Sp1 and Sp2, their respective voltages are induced. By connecting the coils Sp1 and Sp2 so that the voltages cancel each other out, the sum voltage becomes "0" if the coils are the same size and are equally far from the rail.
    When the coils Sp1, Sp2 and Sp3 come close to a rail 30 'of metal, the magnetic field will be affected so that the symmetry is disturbed. This means that the detection coil 10 Sp2 which is closest to the rail 30, has a higher magnetic field and thus a higher voltage is induced in this coil.
    However, when the coils Sp1, Sp2 and Sp3 are located in the middle of the rail 30 ', a symmetry will again occur.
    This can be used to detect with great precision that the pantograph 4 is over the groove 51, 52.
    If the coil Sp1, Sp2 is moved further away, the (+ x) imbalance increases again, but now the coil Sp1 receives a higher signal, which is expressed in the phase position shifting.
    This entails an opportunity to indicate in which direction the pantograph 4 should move to get in the middle of the track.
    This is made possible by the coil Sp3 being used as a phase reference in a phase-correct rectifier.
    Figure 8 shows what a phase-rectified voltage "V" looks like when the coil arrangement Sp1, Sp2 and Sp3 is passed over the rail 30 'and its grooves 51, 52. within the control equipment 10 the following rules are used for controlling the contact or the pantograph 4. 1. If the voltage "V" is negative, according to figure 8, the contact 4 is moved to the right. 2. If the voltage is positive, move contact 4 to the left. 3. When the voltage is zero, the contact 4 is lowered into the groove 51, 52 provided that the absolute value of the voltage shortly before is permanently high.
    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. 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.
