Definitions

  • the invention relates to a control device according to the preamble of patent claim 1.
  • Such a control device is known from DE 29 11 630 C2.
  • This known control device is used for central locking in motor vehicles. It contains an actuator with two end positions, the locking position and the unlocking position, and a control switch with two switch positions, "locking" and “unlocking", which are assigned to these end positions.
  • a control device or equivalent locking and unlocking circuits query the switch position of the control switch and set the actuator in the "lock” switch position to the locked position and in the "unlock” switch position to the unlocked position.
  • the arbitrary setting of the control switch is possible in the known control device, for example, via two rotary positions of a door lock.
  • the invention has for its object to provide a control device according to the preamble of claim 1, with which leaving a prioritized end position of the actuator can be triggered only via the control switch and the control unit.
  • the control unit sends test signals in addition to the signals for setting the actuator via the control line connected to the control switch.
  • the test signals can be repeated any number of times.
  • the response of the control switch to these test signals is in turn detected by the control device over another line.
  • the control unit queries whether the switch position assigned to the non-prioritized end position is clearly set on the control switch. If the setting of this switch position is not recognized, the assigned final position of the actuator, but always the prioritized one, is never set or maintained.
  • This control device carries out the functions assigned to it with additional consideration of safety-related criteria and thus protects against safety-relevant malfunctions through manipulation or errors.
  • the multifunctional use of the control line saves on wiring.
  • control device is designed in such a way that, when operating correctly in both switch positions, at least one first test signal for one and the same test signal, different responses from the control switch can be measured by the control device.
  • the two switchable contacts of the control switch for generating the two possible switch positions are interconnected according to the invention in such a way that, in the event of error-free operation in each switch position, in addition to the different responses to at least one first test signal, a response can be measured for at least one second test signal which differs from that the first test signal measured response differs.
  • the control unit can measure the same responses for all test signals.
  • the possible errors e.g. Interruption, short circuit to plus and short circuit to ground, these answers are the same for all test signals.
  • This individualization of the switch positions according to the invention not only enables the set positions to be clearly identified Switch position, but also the distinction between faultless and faulty operation. In the event of faulty operation, it is also possible to specify the fault in terms of type and duration. Due to the possibility of any repetition frequency of the test signals, even short-term errors or manipulation can be recognized.
  • a further advantageous embodiment of the invention is the subject of claim 4.
  • the control line branches on the one hand directly to a first switchable contact, on the other hand via a one-way valve to the second switchable contact within the control switch.
  • This one-way valve is formed, for example, for a hydraulic control device by a valve which passes the hydraulic fluid in one direction and blocks in the other, or for an electrical control device by a diode which passes the current in one direction and blocks in the other direction.
  • the one-way valve opens in the direction of the second switchable contact.
  • the individualization of the switch positions using a one-way valve is the simplest way to reliably detect an error or the set switch position using the test signals.
  • a further advantageous embodiment of the invention is the subject of claim 5.
  • the control line of the actuator connected to the control switch is used by the control device on the one hand to send the signals for setting the actuator, and on the other hand to send the test signals.
  • the signals for Setting of the actuator and the test signals distinguishable and output at different times on this control line.
  • test signals such as a sequence of positive and negative voltage pulses can be output to the control line during an end position of the actuator.
  • the time is used in which the control lines are not required to adjust the actuator.
  • a further embodiment of the invention is the subject of claim 6.
  • test signals and the signals for setting the actuator can be differentiated - the test signals are also during the actuator drive with a suitable choice of signal forms, e.g. for pulse-width modulated signals, can be output by the control unit.
  • control line is used in a multifunctional manner, a change in the switch position can already be recognized during the actuator drive, and the actuator setting can be changed accordingly quickly.
  • a control unit 1 has two output lines, the control lines SL1 and SL2.
  • An actuator 3 is arranged as an actuator between the control lines SL1 and SL2.
  • the Control line SL1 is additionally connected to input E of control switch 2.
  • the output A of the control switch 2 is connected to the control unit 1 via an input line EL.
  • transistor output stages are attached to the outputs to the control lines SL1 and SL2, as a result of which the control lines SL1 and SL2 can optionally be switched to 12 volts or 0 volts.
  • the input of the control device 1, to which the input line EL is connected, is connected to a voltage divider — consisting here, for example, of two identical resistors R.
  • the input line EL is connected in the control switch 2 to the fixed pole FP of the changeover switch WS.
  • the changeover switch WS has two possible positions, VR ("lock") and ER ("unlock").
  • the VR position the control line SL1 is connected directly to the input of the control unit 1 via the switchable contact SK1.
  • the ER position there is a decoupling diode ED between the control line SL1 and the input of the control device 1, the cathode of which is connected to the switchable contact SK2 and the anode of which is connected to the control line SL1.
  • Such a control device can be used, for example, for locking and unlocking doors in an electrical central locking device.
  • the changeover switch WS of the control switch 2 is actuated, for example, by the position of the safety button or the key in the door lock.
  • the doors of the electrical locking device should be locked in the VR position of the changeover switch WS and unlocked in the ER position of the changeover switch WS.
  • the control unit 1 queries the position of this changeover switch WS via the input line EL and, depending on this, sets the servo motor 3 into one of the respective positions via the control lines SL1 and SL2 Changeover switch WS assigned end position, unlocked position or locked position.
  • the control line SL1 is switched to positive voltage, for example 12V, and the control line SL2 to 0 V, and to set the other end position, the control lines SL1 and SL2 are inverted. If the respective end position of the servomotor 3 is reached, the servomotor 3 is switched off by switching the transistor output stages of the control line SL2 to be non-conductive. If the servomotor 3 is inactive, the control line SL1 is used by the control unit 1 to query the control switch 2 or the changeover switch WS. For this purpose, the control line SL1 is alternately applied with the two test signals 12 volts and 0 volts.
  • test signals can also be output to the control line SL1 while the servomotor 3 is being set. If, for example, the servomotor 3 is clocked to set one of the two end positions, that is to say driven with a signal that changes, for example, between 12 V and 0 V, the signal for setting the servomotor 3 already contains the two test signals, 12 V and 0 V.
  • the control unit 1 measures the voltage U across the resistance R connected to 0 V of the voltage divider simultaneously with the output of the test signals.
  • control line SL1 The alternating loading of the control line SL1 with the two different test signals takes place at a speed which makes it possible to detect manipulation or short-term faults on the control line SL1, the control switch 2 and the input line EL in any case. If an error is detected, various reactions of control unit 1 are possible. For example, the position of the control switch 2 last recognized before the error was recognized can be maintained. According to the invention, however, the locking position is preferably selected as the prioritized end position. If the control unit does not recognize the position ER, the unlocking position is never set at least for a tamper-proof time.
  • the setting of the unlocking position can be activated in order to allow the vehicle owner or the workshop non-destructive access to the motor vehicle interior.
  • control device The various functions of the control device according to the invention are illustrated with this special exemplary embodiment.
  • the control device is used for controlled actuation of an actuator depending on an arbitrarily changeable specification.
  • errors are recognizable to which security-related responses can be reacted, for example to prevent manipulation.
  • lines are saved between the control switch and the actuator by the multiple use of a line. Accordingly, on the one hand, weight and effort can be saved in the cabling, and on the other hand the probability of failure of such a control device can be reduced.
