Definitions
- the present invention is based on an electrical circuit arrangement designed in accordance with the preamble of the main claim.
- Such circuit arrangements are provided in order to permanently maintain a certain functional state of an electrical system having two different functional states.
- This is e.g. B. possible in that the system for initiating the two functional states is directly associated with a power switching device which, in order to implement each of the two functional states, in each case has a switching position to be reached from a starting position, with a latching configuration.
- switching devices that transmit the full power and thus also interrupt the switching devices have been replaced by switching devices, such as so-called silicone switching mats, which can be actuated by touch and only control currents, to which bistable power switching relays are then assigned, for example.
- switching devices such as so-called silicone switching mats, which can be actuated by touch and only control currents, to which bistable power switching relays are then assigned, for example.
- Such embodiments require a considerable amount of effort both in terms of material and in terms of space requirements.
- This also includes a circuit arrangement provided with a conventional flip / flop, which can be influenced by pulse-shaped signals, wherein the pulse-shaped signals can of course also be caused by key switches.
- the present invention has for its object to provide an electrical circuit suitable for existing electrical systems in electronic systems with electronic function storage, in which even in the event of an external or internal malfunction - such as power failure or line interruption - the previously existing functional state over an almost unlimited length Period remains.
- Circuit arrangement is that the same can be implemented with relatively simple means, which only require a very small amount of space.
- FIG. 2 one of the control stages of the circuit arrangement according to FIG. 1 with an associated switching device;
- Fig. 3 the switching module of a control stage.
- an electrical system S present in a motor vehicle for example in the form of a window or sliding roof adjustment device, and connected to the supply voltage U of the motor vehicle electrical system, there are four identically designed control stages ST via a connecting line AL, each with its output A connected, which are also connected to the power supply.
- Each control stage is in turn assigned a switching device SV which has two separate switching elements SV1, SV2 and can be actuated by touch, via which a functionally associated system, which forms part of the system, can be switched between two functional states, for example switched on and off.
- a switching element can be used instead of the two switching elements, in which case the switching between the two functional states can then be implemented by repeated actuations thereof.
- the control stage is provided with a switching module SB which consists of a flip / flop F / F formed in particular by three EEPROM cells which has become a non-volatile structure by using EEPROM technology .
- this bistable electronic switching module is provided with an SO-8 housing, of which the input Vdd is connected to the supply voltage U via a limiting resistor BW in such a way that the power loss converted can be limited in the event of an overvoltage.
- This working voltage is fed via internal switching means SM to the internal supply input Vc, to which a backup capacitor C1 provided for short-term stabilization of the working voltage is connected on the one hand, which on the other hand is connected both to the ground connection GND and also directly to ground.
- the output OUT of the switching module is then routed to connection A of the control stage ST.
- the two connections L1, L0 which are generally referred to as SET, RESET inputs, are connected to the positive pole (+) of the voltage supply via series resistors VW1, VW2 and their associated light-emitting diodes LD1, LD2, which are located in their connecting lines VL1, VL2 the light-emitting diodes working in the visible wave spectrum, preferably one light-emitting diode LD1 emits light beams in the red wavelength range and the other light-emitting diode LD2 light beams in the green wavelength range.
- the switching device SV with the two switching elements SV1, SV2 to be actuated by touch is then connected to the two inputs L1, L0 of the switching module SB or to the connecting lines VL1, VL2 assigned to the same. It is thereby achieved that the state "1" is caused by the actuation of the switching element SV1 at the output A of the switching module SB, while the state "0" is generated when the switching element SV2 is actuated at the output A.
- the respective state assumed is then indicated by the associated LED.
- the electronic switching component SB which is designed in particular as an ASIC, is also included, as can be seen from FIG. 3 the non-volatile flip / flop F / F advantageously formed from three EEPROM cells.
- EEPROM cells are each set to one of their two possible states via a control element AO by a control logic SL connected to the switching elements SV1, SV2.
- An evaluation stage AS downstream of the three EEPROM cells detects via a test component PK whether all the cells are in the same state. If this is the case, the control output SL brings the signal output A to the signal potential defined for this purpose by correspondingly influencing an assigned electronic switching element SG.
- a probability component WK is assigned to the EEPROM cells, by means of which a majority decision is made. This is relevant in the event that a fault has occurred during the change in the state of the EEPROM cells, in which case that of the majority of the cells, i.e. state assumed by two cells.
- the probability component WK directly influences the switching element SG assigned to the signal output A.
