Description

The present invention relates to a circuit arrangement in a towing vehicle, to which a trailer is mechanically and electrically coupled, wherein the towing vehicle and the trailer each have a signal and lighting system between the towing vehicle and the trailer from a socket and plug existing connector for electrical connection the trailer is provided to the towing vehicle, in the towing vehicle, a signal generating system is provided which converts inputs of a driver into control signals for lamps of the signaling and lighting systems and passes via a data bus to the corresponding lamps, and wherein state signals for visual and / or acoustic displays are generated, which provide the driver with information about the condition of individual lamps of the signaling and lighting systems.

The invention further relates to a circuit arrangement in a to a towing vehicle mechanically and electrically coupled trailer, the towing vehicle and the trailer each have a signal and lighting system, between the towing vehicle and the trailer from a socket and plug existing connector for electrical connection of the trailer the towing vehicle is provided, in the towing vehicle a signal generation system is provided, which converts inputs of a vehicle driver into control signals for lamps of the signaling and lighting systems and directs them via a data bus to the corresponding lamps, and wherein status signals for visual and / or acoustic displays are generated; which provide the driver with information about the status of individual lamps of the signaling and lighting systems.

Such circuit arrangements for a towing vehicle or a trailer are from the DE 102 55 301 A1 known.

In general, such circuit arrangements are used to equip a tractor to be able to operate in addition to the own signal and lighting system and the signal and lighting system of a coupled trailer.

In this context, it is not only important that the corresponding signals are routed to the trailer, where there are possibly the direction indicators left and right, the tail lights left and right, the clearance lights left and right, marker lights left and right, license plate light left and right To operate brake lights left and right and rear fog light and / or return light, rather, the driver must also feedback made available, by which he detects whether the signal and lighting system of the trailer is working properly or if certain lamps have failed.

For this purpose, tractors are either already ex-factory, usually after the band assembly in a separate retrofit station, equipped with such circuitry. On the other hand, it is also possible to obstruct the circuit arrangements at a later time to the towing vehicle, which is why the circuit arrangements are also provided as a kit.

The same applies to a greater extent for trailers, where appropriate circuitry either installed from the factory or retrofitted.

The subsequent installation in towing vehicles and trailers is particularly necessary if already delivered tow trucks and trailers to be equipped or retrofitted later for operation with a particular trailer or towing vehicle.

Against this background, the present invention also relates to corresponding kits for retrofitting of towing vehicles or trailers.

Classically, the transfer of the signals between the towing vehicle and the trailer via a plug-in connection from a socket and a plug, where usually the socket to the towing vehicle and the plug are installed on the trailer. There are several DIN / ISO standards, which is known DIN ISO 11446 for 13-pin connectors as well as the DIN 172 for 7-pin sockets.

The present invention can be realized with two types of sockets, where it is preferably used for 13-pin sockets with a corresponding plug.

About these connectors control signals that are provided for lamps of the signaling and lighting system of the towing vehicle, passed in parallel to the lamps of the signal and lighting system of the trailer, which are then energized accordingly with appropriate operation of a switch on towing vehicle.

Circuit arrangements for retrofitting in towing vehicles are widely known from the prior art, for example, be mentioned here are the EP 0 501 014 B1 , the EP 0 539 705 B1 as well as the EP 0 546 244 B1 ,

These circuits not only provide the initially mentioned transmission of control signals to the corresponding lamps of the trailer, they also carry a so-called. Trailer detection, which is needed for different functions in the towing vehicle.

If the towing vehicle is equipped, for example, with a rear fog lamp, it is necessary to switch the rear fog lamp on the towing vehicle without function when a trailer is turned on to avoid corresponding glare. The same applies to return lights.

Furthermore, the known circuit arrangements recognize on the basis of the current flow in the trailer, whether a controlled lamp in the trailer is actually operational, or if, for example, the filament is broken.

The known circuit arrangements have proved to be reliable and functional especially for trailers, in which the lamps of the signal and lighting system are equipped with filament-based bulbs.

Problems arise, however, when the lamps of the trailer are equipped with semiconductor-based bulbs, especially on LED base. Known here are the so-called. LED arrays, which can be used both in the direction indicator, so the turn signals, as well as the other lighting lamps.

The required supply voltage and the current flow in the semiconductor-based bulbs are significantly different from the filament-based bulbs, so it always comes back to problems when a towing vehicle, which is equipped to operate with a trailer that contains filament-based bulbs to draw a trailer , in which semiconductor-based bulbs are used. The same applies to the opposite case, when the towing vehicle is set up to tow a trailer, in which the bulbs operate on a semiconductor basis, and then a trailer is coupled with incandescent-based bulbs.

So far, no circuit arrangement is known which operates reliably and offers the possibility of structurally acceptable effort to couple to a towing vehicle optionally a trailer with incandescent or semiconductor-based bulbs, without affecting the function of the signal and lighting system of the trailer or even jeopardizes the feedback of error detection signals becomes.

In addition, it is known that modern towing vehicles are no longer equipped with a conventional wiring harness, in which each cable in the cockpit a cable is led directly to the lamp to be switched, but in which so-called. Data bus systems are used, such as the CAN -Bus.

The circuitry for such towing vehicles must co-operate with the data bus to pass control signals and to return state signals.

In this context, the above-mentioned DE 102 55 103 A1 a circuit arrangement in which the signals between the towing vehicle and the trailer are exchanged via a data transmission cable, which is transmitted via a special plug connection between towing vehicle and trailer.

In the known circuit arrangement no control signals are transmitted between the towing vehicle and the trailer, which are directly suitable for driving the light source in the trailer, but only signals are transmitted, which are implemented in the trailer in corresponding drive signals for the light source in the lamps.

The document mentions the possibility to pass the data transmission via a 7-pin or 13-pin connector, but does not consider this to be particularly functional and therefore proposes to dissolve the data transmission from the previous motor vehicle coupling and its own data box or a to choose wireless data transmission.

In the known circuit arrangement, it is therefore necessary to provide both the towing vehicle and the trailer special assemblies and fasteners, on the one hand allow the exchange of data between the towing vehicle and the trailer, but on the other hand ensure the control of the light source in the trailer.

This means, however, that towing vehicle and trailer must be specially matched to each other, so that equipped with the known circuit arrangement towing vehicle can not be used to tow a trailer and reliably operate its signaling and lighting system when the trailer is not specifically on the Traction vehicle is tuned.

This is particularly disadvantageous because many drivers only occasionally need a trailer, which is then lent on a case-by-case basis. On the other hand, drivers have been driving for For many years a trailer that they want to move with each newly purchased towing vehicles.

If a new towing vehicle is then equipped with the new circuitry, the trailer must be retrofitted accordingly, in which case still other trailers could not be operated.

Against this background, the object of the present invention is to refine the known circuit arrangement in such a way that the abovementioned disadvantages are avoided in a constructively simple effort in a reliable manner. In particular, it should be possible to be able to move different trailers with a traction vehicle equipped with the new circuit arrangement without safety problems occurring.

In the above-mentioned circuit arrangement in a towing vehicle, this object is achieved in that it comprises a bus module and a driver module, wherein the bus model is connected to the data bus and the driver module to the bus module and / or the data bus and contacts of the connector, the driver module in response to information received from the bus module or the data bus to associated contacts of the connector provides control signals that are suitable for direct control of glow-based bulbs of the signal and lighting system of the trailer, and the bus module is connected via at least one bus line to a contact of the connector ,

In the above-mentioned circuit arrangement in a trailer, this object is achieved in that in the trailer a trailer bus module is provided, which is connected to lamps of the signal and lighting system of the trailer and at least one bus line with a contact of the connector and set up to transmit via the at least one bus line state signals preferably via lamps of the signal and lighting system of the trailer to a provided in the towing vehicle bus module which is connected via at least one bus line with a contact of the connector.

The problem underlying the invention is completely solved in this way.

In fact, the inventor of the present application has recognized that it is possible in a structurally simple manner to drive "double-railed", so to speak. Through the driver module control signals are applied to the contacts of the connector, which are suitable to operate directly incandescent-based bulbs in the trailer. In that regard, the driver module in its function is comparable to a conventional driver module, as it is from the above-mentioned EP 0 501 014 B1 . EP 0 539 705 B1 such as EP 0 546 244 B1 as well as other publications from the prior art is known.

This driver module is supplied via the bus module or directly via the data bus with appropriate information that cause the driver module to provide the appropriate control signals, ie the analog voltage values at the corresponding contacts of the connector. The driver module can be connected only to the data bus or alternatively or additionally to the bus module, so that the driver module can exchange information with the data bus and / or the bus module.

Now, if a trailer is coupled to the towing vehicle, which is not designed to communicate with a data bus and contains filament-based bulbs, so this trailer can be operated in the classic way. Its light sources are operated directly via the control signals at the contacts, wherein the driver module is equipped to monitor the current flow through the controlled lamps and possibly give error messages, as is also already known from the cited prior art.

In contrast to the cited prior art, however, the driver module is not directly connected to the corresponding lamps of the signaling and lighting system of the towing vehicle, that is connected in parallel thereto, but receives its information via the data bus, for which it is preferably connected to the bus module.

The bus module itself is now connected via at least one bus line with a contact of the connector, so that it can communicate with a trailer bus module, if such a trailer bus module is present in the trailer coupled.

If such a trailer bus module is provided, the state signals can be transmitted via the function of the lamps of the signal and lighting system of the trailer in the towing vehicle and evaluated accordingly there, so that the status signals via visual and audible indications communicated to the driver via the two bus modules can be.

Classically, this is in a malfunction of a direction indicator, the doubled flashing frequency or a signal lamp in the cockpit, which always lights up when one of the lights of the trailer lamp serving was controlled, but has failed.

Via this data bus connection between the trailer and the towing vehicle, control signals can now also be transmitted, which are used in the trailer to drive the individual lamps of the signaling and lighting system.

In other words, the plug-in connection transmits data bus signals between the towing vehicle and the trailer to a possibly multiple contacts and supplies the usual voltage signals to the remaining contacts which are directly suitable for the operation of incandescent-based lamps.

If now in the trailer not incandescent-based but semiconductor-based bulbs are provided, then either the signals on the contacts or transmitted via the data bus signals from the trailer bus module can be used to operate the corresponding bulbs in the trailer, including the monitoring the lamps in the trailer is guaranteed.

Due to the circuit arrangement according to the invention in the towing vehicle, it is now possible to couple and operate different types of trailers, without the driver having to worry about whether the corresponding trailer can be coupled at all.

If the trailer is an older model that uses filament-based light bulbs and is not yet equipped with its own bus module, the control and monitoring of the trailer's signaling and lighting system will be carried out in the usual way via the norm Contacts of the connector.

If, in contrast, semiconductor-based illuminants are present in the trailer, this is to be taken into account by an appropriate interconnection in the trailer, the activation and control of the illuminants then takes place via the trailer bus module, which communicates with a bus module in the towing vehicle via a corresponding bus line.

In this way, the problem is solved as a fault detection in the towing vehicle works reliably when it is not known in the towing vehicle, whether the trailer is provided with incandescent or semiconductor-based bulbs. This information must now be present only in the trailer, which then causes the control of the light source and transmitted via a corresponding bus module status signals to the towing vehicle back.

In a further development, it is preferred if the socket is a multi-pole, preferably a 13-pin, more preferably a DIN ISO 11446 corresponding socket is that is mounted on the towing vehicle, and preferably when the control signals are provided at least at the contacts associated with a direction indicator left or right, brake lights and tail lights left or right of the signaling and lighting systems of the trailer.

In this measure, it is advantageous that the circuit arrangement cooperates with the usually provided automotive clutches according to DIN.

Further, it is preferred if the at least one bus line is connected to a provided in the socket contact for Dauerplusübergabe or trailer detection.

The inventor of the present application has recognized, on the one hand, that a "single-wire data bus" is sufficient for the data transfer between towing vehicle and trailer in question, with the bus line provided either via the contact for trailer recognition or via the contact can be connected for the continuous plus transfer, if the connector has no free contact that can be used for data transmission.

The contact for the trailer detection is usually not connected anyway or this function is taken over by the data bus, so that this contact is freely available. On the other hand, it is also possible to impose the corresponding data signals of the permanent plus transfer, since only small amounts of data must be exchanged, which can be transmitted very securely by suitable coding.

Further, it is preferred if the bus module is adapted to detect via signals on the at least one bus line, if a trailer bus module is provided in an electrically connected via the connector to the towing vehicle trailer, with lamps of the signal and lighting system of Trailer is connected.

If the bus module in this way recognizes that a corresponding bus module is also present in the trailer, it can query the status signals from the trailer bus module, so that the query about the driver module provided in the towing vehicle is not required.

In this case, it is then also preferred if the bus module is set up to control the control signals for driving lamps of the signal sources. and lighting system of the trailer via the at least one bus line to a trailer provided in the trailer bus module, which is connected to the lamps of the signaling and lighting system of the trailer.

In this measure, it is advantageous that it is not absolutely necessary to apply the analog control signals to the contacts of the socket via the driver module, the driver module can possibly be switched without function.

It is further preferred if the bus module is set up to receive status signals from the trailer via the at least one bus line from a trailer bus module provided in the trailer and to forward them via the data bus, whereby the bus module may be adapted from the driver module Receive status signals from the signaling and lighting system of the trailer.

Depending on the equipment of the trailer, the bus module can now receive status signals via the bus or from the driver module and further processed accordingly, so that the transmission of information to the driver is given in any case.

In the context of the present invention, a "trailer" is understood to mean not only single-axle or multi-axle vehicles, but also braked or unbraked trailers, ie those with their own chassis, but also, for example, bicycle carriers which are mounted on the rear of the towing vehicle and have their own signaling and lighting system. which must be supplied via the plug connection and queried. A "towing vehicle" is therefore in the context of the present invention, both a car and another motor vehicle, which can be interconnected with a trailer.

The status signals include a trailer detection signal that indicates whether a trailer is electrically connected to the towing vehicle, and possibly error detection signals that indicate whether a controlled lamp of the signaling and lighting system of the trailer has a malfunction. Further, the status signals may include information about the type of trailer used in the towing vehicle for vehicle dynamics control.

In a corresponding manner, the circuit arrangement is equipped in the trailer, wherein the trailer bus module provided there is preferably adapted to receive via the at least one bus line provided by the towing vehicle in the bus control signals for controlling the lamps of the signal and lighting system of the trailer ,

The advantage here is that the trailer bus module must be connected only via a bus line with a contact of the connector and other lines with the corresponding lamps of the signal and lighting system, connections to other contacts of the connector are not required.

This measure is therefore particularly advantageous when retrofitting a trailer with the new circuit arrangement, since it is relatively easy to perform. For the lamps of the signal and lighting system, it is then irrelevant whether they contain filament-based or semiconductor-based bulbs, this is taken into account in the selection of the trailer bus module.

If the lamps are filament-based, they can each be connected to an associated contact of the connector, so that they are operated directly via the control signals from the towing vehicle. Because of the connection of the lamps with the trailer bus module, however, the status signals can be generated there and reported via the bus to the towing vehicle.

Against this background, the present invention also relates to a kit for a signaling and lighting system of a towing vehicle, to which a trailer can be coupled mechanically and electrically, having a signal and lighting system, between the towing vehicle and the trailer consisting of an outlet and plug Plug connection for electrical connection of the trailer is provided to the towing vehicle. The kit has a new circuit arrangement as described above.

The same applies to a kit for a signaling and lighting system of a trailer, which contains the circuitry described above for the trailer.

The trailer bus module does not necessarily have to be installed in the trailer. It is also possible to implement the trailer bus module in an adapter plug, so that the expensive electrical system is not permanently and firmly mounted in the trailer, but if necessary can be plugged onto the connector present on the trailer and then between socket and plug in the Plug connection is seated.

Further advantages will become apparent from the description of the accompanying drawings.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

An embodiment of the invention is illustrated in the drawing and will be explained in more detail in the following description. Show it:

1 a schematic representation of the interconnection of the signaling and lighting systems of a towing vehicle and a trailer, with schematically illustrated circuit arrangements;

2 the signaling and lighting system of a trailer, as with the towing vehicle 1 is also usable; and

3 a schematic representation of a driver module, as in the circuit arrangement in the towing vehicle according to 1 is used.

In 1 is schematically a towing vehicle 10 pictured with a pendant 11 being connected, being towing vehicle 10 and followers 11 one signal and lighting system each 12 respectively. 14 exhibit.

Between the towing vehicle 10 and the trailer 11 is a plug connection 15 from a socket mounted on the towing vehicle 16 and one with the trailer 11 connected plug 17 intended.

In the towing vehicle 10 is a signal generation system 18 provided in response to signals that a driver over at 19 schematically indicated direction switch and various light switches, one of which at 21 is indicated.

From these inputs of the driver produces the signal generation system 18 Control signals over a data bus 22 to lamp 23 the signal and lighting system 12 of the towing vehicle 10 be directed.

In the simplest case, these control signals are control voltages U _S , directly on the lamps 23 operate. The lamps 23 can contain both filament-based bulbs and semiconductor-based bulbs such as LEDs.

The signal generation system 18 also monitors the function of the lamps 23 and generates status signals which are routed to displays, of which 1 indicator lights 24 are shown. The status signals are in the simplest case voltages U _Z , over which the indicator lamps 24 operate.

In the towing vehicle 10 is the new circuit arrangement 25 arranged over which the signal and lighting system 12 of the towing vehicle with the signaling and lighting system 14 of the trailer 11 can communicate.

The circuit arrangement 25 includes a bus module 26 and a driver module 27 ,

The bus module 26 is over a line 28 with the data bus 22 and over a bus line 29 with a contact 31 in the socket 16 connected.

In this way, the bus module 26 Data from the data bus 22 to the contact 31 direct or received from there data in the data bus 22 feed.

About a line 32 is the bus module 26 with the driver module 27 connected in turn via corresponding lines with contacts 33 in the socket 16 connected is. At these contacts 33 puts the driver module 27 Control signals U _S ready, which are suitable to drive filament-based bulbs.

Which contacts 33 each have to be acted upon with a control signal U _S , the driver module 27 from the bus module 26 communicated this information in turn from the data bus 22 receives. Alternatively, the driver module 27 also directly with the data bus 22 be connected, the line 32 can be additionally provided.

The power outlet 16 is still with a contact 34 equipped for the permanent plus transfer (V _CC ). Furthermore, in the socket 16 a contact 35 provided, the zugfahrzeugseitig is connected to ground.

Trailer side are in the plug 17 accordingly a contact 36 for permanent plus delivery as well as a contact 37 provided for the ground connection.

Furthermore, there are various contacts 38 provided the contacts 33 are assigned, to which the control signals from the driver module 27 be created.

Finally, in the plug 17 another contact 39 provided, to which a bus line 40 connected to a trailer bus module 41 leads, one in the trailer 11 assembled circuit arrangement represented.

The trailer bus module 41 is via lines 42 with the contacts 38 connected.

On the output side, the trailer bus module is via a line 43 with a brake light 44 , via a wire 45 with a right turn signal 46 , via a wire 47 with a left direction indicator 48 , via a wire 49 with a right tail light 50 and over a line 51 with a left tail light 52 connected.

The lamps 44 . 46 . 48 . 50 . 52 are LED displays in the embodiment shown.

In operation of the tractor 10 and followers 11 existing vehicle train gives the driver via a light switch 21 or the direction switch 19 in front of which lamps in the towing vehicle 10 and in the trailer 11 should be pressed. This information is provided by the signal generation system 18 processed and as control signals on the data bus 22 output. At the same time, control signals are sent via the line 28 to the bus module 26 That this information is on the line 32 to the driver module 27 forwards. The driver module 27 makes sure that at appropriate contacts 33 the socket 16 Control signals pending, now through the contacts 38 in the plug 17 to the trailer bus module 41 be routed and evaluated there so that the corresponding of the lamps 44 - 52 be controlled.

If in one of the controlled lamps 44 - 52 an error condition occurs, this is from the trailer bus module 41 detected and via the bus line 40 and the contacts 39 / 31 as well as the bus line 29 to the bus module 26 passed this information over the line 28 and the data bus 22 to the signal generation system 18 leads, which then generates corresponding status signals.

Because both the towing vehicle 10 as well as the trailer 11 one bus module each 26 respectively. 41 it is with appropriate design of the trailer bus module 41 technically not absolutely necessary, this over lines 42 with the contacts 38 rather, can connect the control signals for the lamps 44 - 52 the signal and lighting system 14 of the trailer 11 also over the bus lines 29 and 40 be transmitted. To ensure compatibility with older towing vehicles, the connections can 42 nevertheless be provided in addition.

It should be noted that the lamps 44 - 52 may also be filament-based lamps driven directly by the trailer bus module.

In 2 is an alternative trailer 11 hinted at which the lamps 44 - 52 are filament-based. In this case, the lamps are 44 - 52 directly with the contacts 38 of the plug 17 They are also connected simultaneously via the lines 33 - 51 with the trailer bus module 41 can be connected.

The control of the filament-based lamps 44 - 52 This is done directly via the contacts 33 / 38 ,

However, the error detection takes place via the trailer bus module 41 , the corresponding error conditions via the bus line 40 reports. Alternatively, error detection can also be done conventionally via the driver module 27 take place, as is known in principle in the prior art.

To the towing vehicle 10 with the circuit arrangement 25 can now both followers 11 be connected, where no trailer bus module 41 is provided, that is filament-based bulbs 44 - 52 have, directly through control signals from the contacts 38 operated as well as followers 11 without trailer bus module.

If a trailer bus module 41 is provided, this recognizes the bus module 26 in the towing vehicle 10 , so that then optionally the control signals U _S via the contacts 33 or over the bus line 29 and the contact 31 to the trailer bus module 41 can be directed.

The trailer bus module 41 then can the lamps 44 - 52 either via separate lines 43 - 51 it is also possible that the lines 43 - 51 to those with the contacts 38 directly connected bulbs 44 - 52 be guided.

Thus it is possible to use different types of trailers 11 with the new circuit 25 equipped towing vehicle 10 to operate. Alternatively, you can also use the trailer bus module 41 equipped trailer 11 be connected to towing vehicles that are not a bus module 26 exhibit.

The driver module 27 is for a part then necessary if in the trailer 11 no trailer bus module 41 is provided, wherein the driver module 27 is also provided if a trailer bus module 41 is present, but the control signals still through the contacts 38 be transmitted.

In 3 is the driver module 27 shown schematically. It contains an input module 54 that directly over the line 32 with the bus module 26 connected is.

Furthermore, the driver module contains 27 a driver circuit 55 , in the individual circuits 56 . 57 . 58 . 59 . 60 and 61 are provided, of which the circuits 56 - 60 each with both the circuit 61 as well as with contacts 33 in the socket 16 are connected.

The circuits 56 - 60 serve to provide control signals for filament-based lamps of the trailer and at the same time to check these filament-based lamps for malfunction, as in principle from the above-mentioned EP 0 501 014 B1 . EP 0 539 705 B1 such as EP 0 546 244 B1 is known.

The circuits 56 - 60 are also each indicated by arrows signal paths with the circuit 61 connected, which serves the trailer detection, as is also known from the cited prior art.

Each of the circuits 56 - 60 is also connected to the input module 54 connected to that from the bus module 26 originating information is generated control signals, each via lines 62 - 66 directly to the circuits 56 - 60 be forwarded. The control signals on the lines 62 - 66 correspond to the usual control signals for filament-based illuminants.

If in one to a towing vehicle 10 hitched trailer 11 a trailer bus module 41 is provided, the driver module 27 over the line 32 also be switched off.

The trailer bus module 41 can also be used to the towing vehicle 10 to communicate about status signals, what a trailer 11 it is about. This information can be in the towing vehicle 10 used to regulate the driving dynamics.
