Definitions
- the invention relates to a central locking system for motor vehicles, with a number of actuators, each of which has a signal unit which, depending on current state parameters, of an opening and / or an operating element of the motor vehicle monitored by it or as a function of external input ⁇ the specified command signals forwards data signals to a control unit, which generates control signals from these data signals, with which control elements of the central locking system are actuated, which effect the locking and unlocking of the openings of the motor vehicle.
- Such a central locking system is known from DE-OS 36 28 706.
- Each actuator of the central locking system is connected via a bus system to a central processor which evaluates the status parameters of the doors of the motor vehicle registered by the signal transmitter units of the individual actuators.
- the data signals supplied by the signal transmitters are then converted into control signals for the control elements of the central locking in accordance with a program stored in the central processor. This will then be fed to the control elements in turn via the bus system.
- a disadvantage of the known central locking system is the extremely complex signal flow: the signals must first be routed from each actuator to the central processor and the control signals calculated therein must then be routed to the actuating elements of the central locking system. This bidirectional signal flow between actuators or adjusting elements and the central processor disadvantageously requires complex bus management.
- the task of the invention is to develop a central locking system of the type mentioned at the outset in such a way that the signal flow required for operating the central locking system is simplified.
- FIG. 1 shows a functional diagram of a first exemplary embodiment
- Each actuator 1-4 has a signal transmitter unit 12a-12d consisting of at least one signal transmitter.
- a first signal transmitter 13a of the signal transmitter unit sends a data signal which indicates whether the door to be monitored is opened or pre-latched or closed.
- a second signal transmitter 13b indicates that the door is completely closed.
- the third to fifth signal transmitters 13c-13e serve to control the central locking system by the user of the motor vehicle: the third signal transmitter 13c registers via an external input signal, for example a specific position of the car key in the door lock, that the user has one with the central locking device would like to activate interlocking theft protection.
- the fourth and fifth signal transmitters 13d and 13e register that the user is opening or closing the motor vehicle.
- a bus system 30 which is transmitted in time-division multiplex to the messages sent by the actuators 1-4.
- This bus system 30 is advantageously designed as a multi-master bus system, so that each actuator 1-4 can request the bus system 30 via an interface logic integrated in the control unit 20a-20d.
- the bus system 30 can be managed by a known bus arbitration method.
- a first message bit indicates the position of the door assigned to the respective actuator: the value "1" of the first message bit means that this door is completely closed.
- the first message bit is followed by a second message bit, which is used to switch on an interior light 5 of the motor vehicle: the value "1" or "0" of the second message bit indicates that this door is closed or preparatory is steady or open.
- the decentralized control of the central locking system described here has the advantage over the conventional systems with a central control that it enables a drastic reduction in the signal information to be transmitted: with conventional central locking systems, all information of each signal generator of each actuator must be available Central electronics are transferred and the control signals calculated therefrom by the central electronics are brought back to the control elements of the central locking and the anti-theft device arranged on the doors of the motor vehicle and interacting with the respective actuator.
- a transmission of control signals for the movement of the actuating elements of each actuator is not relevant for the other actuators, since each actuator 1-4 independently determines these for the actuating elements assigned to it :
- Such a signal transmission between the individual actuators can therefore be completely omitted in a particularly advantageous manner.
- the signal flow required for the function of the central locking system is therefore drastically reduced.
- the decentralized control of the central locking system makes it particularly easy to integrate the so-called comfort functions of a central locking system - such as an individual locking and unlocking of a specific door of the motor vehicle.
- the decentralized control used in the described central locking system requires that - since a central processor is not provided - the control units 20a-20d of each actuator 1-4 themselves generate the system cycle required for their data processing.
- the signals on the bus system 30 are then sampled with the system clock specific to the respective control unit 20a-20d.
- the system clocks of the individual actuators 1-4 For correct data transmission via the bus system 30, it is therefore necessary for there to be a correlation between the system clocks of the individual actuators 1-4.
- this can be done in a known manner in that each actuator 1-4 has a highly precise oscillating quartz, so that the individual system clocks are sufficiently precise in period.
- the synchronization of the individual actuator cycles can also take place in that an actuator is designed as a clock master.
- the distribution then takes place on the bus in message format. It is also particularly advantageous to proceed as follows:
- the receiving actuator thus knows the length of a bit of the sending actuator in units of its own system clock and can therefore temporally resolve the incoming signal data accordingly.
- This particularly simple solution to the synchronization problem which occurs in a central locking system with decentralized control allows a less precise and therefore cheaper oscillator - such as an RC oscillator - to be used to generate the system clock, thereby reducing the manufacturing costs of the control unit of everyone Actuator be reduced. It is also advantageous that such a correlation determination has a high error tolerance with respect to deviations in the different system clocks of the actuators, which can then be in a range of 30-200%.
- FIG. 2 corresponds essentially to that of FIG. 1, so that the same parts are provided with the same reference numerals.
- the main difference between these two embodiments is that, instead of the bus system 30, four parallel lines 30a-30d are used for data transmission, on which the state of each bit is statically or dynamically transmitted in parallel between the actuators.
- the number of lines required is determined by the number of bits of a status message to be transmitted. This has the advantage that the multiplex format signals required in the time-division multiplex method can be omitted in the case of such a signal transmission, which further simplifies the control electronics.
