- a second can be used in addition to the usual signal line
- Wire connection can be designed as a reference line.
- This reference line can be a Establish a connection to activate an immobilizer and / or alarm system or be connected to a redundant connection of the control unit. A Cutting the reference line, possibly together with the signal line, then leads to Alarm signal, possibly to a blocking of the control element or prevents moving away of the vehicle.
- a wire connection is used signal inverse to the output signal of a signal generator on the other wire connection transfer.
- the inversion is here by an active component, preferably in the area of the signal generator, with which preferably also generates a periodic signal becomes.
- the control unit is set to process such signals. For a potential A burglar is the generation and application of such signals to severed lines usually not possible.
- a coded Signal is transmitted as the output signal of a signal generator, the coding vehicle and / or door-specific.
- Voltage coding is simple and practical feasible using a resistance ratio of resistors in the wire connections and / or can take place via diodes assigned to a signal transmitter.
- For a high Security is different on the two or multi-wire connections transmit coded signals.
- Such coding is from a potential burglar difficult to see through and usually not comprehensible, especially not if there are different codes in every vehicle and on every door are used.
- a self-learning control device is preferred used, which learns the coding used in normal operation and with others, supplied code signals blocked and / or an alarm system and / or an immobilizer controls.
- the multi-wire, in particular two-wire connection according to the invention is also one Central locking device can be used in which each actuator has a decentralized control unit is assigned and the decentralized control units are connected to a central control unit are.

In Fig. 1, these input resistances are only understandable Representation drawn outwards.
- the output signals I1 and I9 the signal generator 5a and 7a corresponding to the resistance ratios R11, R31; R12, R32 as well as R21, R41; R22, R42 coded and as coded output signals I1a1, I1a2 and I9a1, I9a2 transmitted.
- the voltage level transmitted by the signal generators 5a, 7a is therefore dependent on the above-mentioned Resistances and resistance relationships. It becomes a potential burglar difficult when cutting through the plurality of different output signals carrying lines 51, 52 and 71, 72, an effective level for opening the doors of the To find motor vehicle. This is particularly difficult because of the two-wire connections at two inputs of the control unit 9 for opening a door at the same time two him unknown, different signal levels would have to apply. At best, this would also be for a knowledgeable burglar with a lot of time, who during breakouts and Theft is usually not available.
- the coding of the output signals can be Use I1 and I9 of signal generators 5a and 7a.
- a central locking device shown in Fig. 2 is each of the doors VL, VR, HL and HR with an actuator 1 to designed as a door lock 4 equipped, the actuators 1 and 2 in turn the signal generator 5a, 7a, which is an output signal Deliver I1, I9 to open the central locking device and the signal transmitter 5b, 7b, which is an output signal for closing the central locking device deliver, exhibit.
