- the invention is based on a method for transmitting data via a line from a first sensor to a control device nach.der type of independent claim.
- the inventive method with the features of the independent claim has the advantage e. It is known that now several sensors can be connected in parallel to a line. To give each sensor a chance to send its data, this data is sent in consecutive time slots. The triggering event for transmission is an upshift to a first energy level by the controller on the line. This upshifting of the energy detect the sensors, so that this timing leads to the triggering of the timing control in the individual sensors. Each timing control in each sensor tells the particular sensor when to send. The timing controls are on each other
- the controller will return the energy level to a quiescent level, then re-energize and then initiate transmission of the sensors data.
- sensors impact sensors, pre-crash sensors, but also occupant position sensors, such as weight sensors or video sensors come into question here. These may be connected together on a line, or else on different lines, so that in each case one type of sensor is connected to a line.
- the sensor is very simply configured to allow unidirectional data transfer from the sensor to a controller to a controller and without resorting to bus technology.
- the transmission is purely event-driven and runs without any complex bus protocol communication. This results in a high reliability and a low-cost and simple product.
- the sensors can be designed very simply with respect to their electronics.
- All sensors are thus connected in parallel to an interface line.
- Each sensor is assigned a specific time interval, for example by programming a parameter in the sensor.
- the line is usually designed as a two-wire line. However, it is possible to make them as a single-wire line.
- the timing control in the sensors ensures that each sensor transmits its data only in the time interval assigned to it.
- the time intervals and the times of data transmission are designed such that overlaps are avoided.
- the sensors have means for detecting the voltage or the voltage change in order to detect the first or second energy level.
- This second energy level which is characterized by a second voltage, ensures that the sensor is always operated, ie that when the first energy level is switched on, the sensor is not reset.
- impact sensors and also sensors for detecting the occupant position are connected via lines to a control unit which controls restraint means. It has become established that this communication often takes place unidirectionally, ie from the sensors to the control unit, but not vice versa.
- a sensor has a single line to the controller and a second sensor another line. This limits the number of sensors that can be connected to a control unit.
- the term line here refers to a line of two wires, but always a single-wire line is possible.
- the triggering event for the timing control is an increase in the energy on the line to which the sensors are connected in parallel.
- the first sensor recognizes accordingly, as well as all others
- each sensor is given a time slot assigned by its timing control to send its data to the controller.
- These timeslots are already programmed by the manufacturer so that they do not overlap. So there is a vote manufacturer side of the send slots.
- FIG. 1 Illustrates in a block diagram the invention.
- a control unit SG To a control unit SG are connected via a line L, which is designed as a two-wire line, sensors S1, S2 to Sn parallel to each other.
- the voltage level US On the line L, the voltage level US is applied.
- This voltage level US is impressed on the line L by the control unit SG.
- the control unit SG thus serves as an energy source for the sensors S1, S2 to Sn connected to the line L.
- the energy consumption is used by the control unit to verify the number of connected sensors to the line L.
- the sensors S1, S2 to Sn transmit unidirectional data to the control unit SG, which has a receiver module for receiving this data.
- the control unit SG controls, for example, retaining means such as airbags or belt tensioners.
- a mechanism is to be provided which controls the transmission of the individual sensors S1, S2 to Sn.
- the transmission process be initiated via the variation of the voltage US on the line L, while the individual sensors S1, S2 to Sn each have a timing control which is designed such that it transmits a respective one to each sensor S1, S2 to Sn Allocates time slot for transmission, ie overlaps of these time slots are avoided. Therefore, the timing control in the individual sensors S1, S2 to Sn manufacturer must already be set to match these time slots to each other. This means that the sensor S1 first sends its data in a time interval and that in a subsequent time interval the sensor S2 then sends its data. This is done until the last sensor Sn has sent its data.
- the sensor S1 again sends its data in a predetermined time interval, so that there is a cyclic loop for transmitting the sensor data.
- the controller SG shuts down the voltage on the line L to stop the transmission.
- the event that triggers transmission is increasing the voltage US.
- the voltage US can be increased in one jump, or gradually. If the voltage US exceeds a threshold value, as tested by the individual sensors S1, S2 to Sn, then the time is fixed at which the timing starts.
- the voltage US represents an energy level assigned to the sensors S1, S2 to Sn.
- there is a quiescent phase voltage U1 which allows the operation of the sensors without having to reset them when they should resend. It will be as I said, kept for the whole transmission phase and at the elevated voltage level.
- FIG. 1 under the block diagram also a time diagram is given. It is a voltage-time diagram showing the voltage US on the one hand and the transmission phase of the individual sensors on the other hand. First, the voltage level US is at the voltage Uoff.
- the voltage can be switched on and off by the control unit. Thereby, e.g. a reset of the sensor can be performed. Normally, once the vehicle is started, the sensor is turned on once by the controller (voltage to US) and then remains on until the ignition is turned off again.
- the voltage is raised to the value U1, which does not yet trigger the transmission of the sensors S1, S2 to Sn, but supplies them with sufficient energy without having to reset them when they are to transmit.
- the voltage US is raised to the value U2 for a predetermined period of time. In this period, the individual sensors S1 to Sn in the time sections Ts1, Ts2 to Tsn send their data S1, S2 to Sn. After this period, the control unit SG lowers the voltage US to the value U1 again, and then raise it again to the value U2, so that then the transmission cycle starts again.
- the voltage US remains at the voltage U2 and cyclically send the sensors their data.
- FIG. 2 explains in a flow chart the invention.
- the voltage U.sub.s is raised from the value U.sub.1 to the value U.sub.2 in order to trigger the transmission of the sensors S1, S2 to Sn.
- the sensors S1, S2 to Sn detect that the voltage has been raised. In this case, an absolute value detection comes into question, or a voltage change. With this raising, the timing control is started in step 202.
- the sending of the data is then carried out by the individual sensors S1, S2 to Sn in their assigned time slots.
- the controller SG lowers the voltage from U2 to U1 after the last sensor has sent its data. Then, in step 205, the method ends. As indicated above, there are several ways to perform this procedure cyclically or controlled by raising and lowering the voltage US on line L.
Description
Die Erfindung geht aus von einem Verfahren zur Übertragung von Daten über eine Leitung von einem ersten Sensor zu einem Steuergerät nach.der Gattung des unabhängigen Patentanspruchs.The invention is based on a method for transmitting data via a line from a first sensor to a control device nach.der type of independent claim.
Aus
Ein weiteres Übertragungsverfahren nach dem Stand der Technik ist aus DE 3 330 904 A bekannt.Another prior art transfer method is known from DE 3 330 904 A.
Das erfindungsgemäße Verfahren mit den Merkmalen des unabhängigen Patentanspruchs hat Vorteile. Es ist bekannt, dass nunmehr an eine Leitung mehrere Sensoren parallel angeschlossen werden können. Um jedem Sensor eine Möglichkeit zu geben, seine Daten zu senden, werden diese Daten in aufeinanderfolgenden Zeitschlitzen gesendet. Das auslösende Ereignis für das Senden ist ein Hochschalten auf ein erstes Energieniveau durch das Steuergerät auf der Leitung. Dieses Hochschalten der Energie detektieren die Sensoren, so dass dieser Zeitpunkt zur Triggerung der Zeitablaufsteuerung in den einzelnen Sensoren führt. Jede Zeitablaufsteuerung in jedem Sensor sagt dem jeweiligen Sensor, wann er dann senden kann. Die Zeitablaufsteuerungen sind dabei aufeinander The inventive method with the features of the independent claim has the advantage e. It is known that now several sensors can be connected in parallel to a line. To give each sensor a chance to send its data, this data is sent in consecutive time slots. The triggering event for transmission is an upshift to a first energy level by the controller on the line. This upshifting of the energy detect the sensors, so that this timing leads to the triggering of the timing control in the individual sensors. Each timing control in each sensor tells the particular sensor when to send. The timing controls are on each other
abgestimmt, so dass es zu keinen Überschneidungen beim Senden der Sensordaten kommt. Das Verfahren endet, wenn der letzte Sensor seine Daten gesendet hat. Es ist möglich, dass dann wieder der erste Sensor seine Daten sendet, so dass zyklisch alle Sensoren ihre Daten senden können. Es ist vorsesehen, dass nach dem Senden der Daten des letzten Sensors das Steuergerät das Energieniveau wieder auf einen Ruhepegel zurückfährt, um dann erneut Energie hochzufahren und dann das Senden der Daten der Sensoren zu veranlassen.matched, so that there is no overlap when sending the sensor data. The process ends when the last sensor has sent its data. It is possible that then again the first sensor sends its data, so that cyclically all sensors can send their data. It is to be understood that after transmitting the data from the last sensor, the controller will return the energy level to a quiescent level, then re-energize and then initiate transmission of the sensors data.
Als Sensoren kommen hier Aufprallsensoren, Precrashsensoren, aber auch Insassenpositionssensoren, wie Gewichtssensoren oder Videosensoren in Frage. Diese können gemeinsam an einer Leitung angeschlossen sein, oder aber auch an verschiedenen Leitungen, so dass jeweils eine Art eines Sensors an einer Leitung angeschlossen ist. Der Sensor ist sehr einfach konfiguriert, um eine unidirektionale Datenübertragung vom Sensor zu einem Steuergerät zu einem Steuergerät zu ermöglichen und ohne auf eine Bustechnik zurückzugreifen. Hier ist das Senden rein ereignisgesteuert und läuft ohne eine aufwändige Busprotokollkommunikation ab. Dies führt zu einer hohen Zuverlässigkeit und zu einem kostengünstigen und einfachen Produkt. Insbesondere können die Sensoren dabei sehr einfach bezüglich ihrer Elektronik ausgeführt sein.As sensors, impact sensors, pre-crash sensors, but also occupant position sensors, such as weight sensors or video sensors come into question here. These may be connected together on a line, or else on different lines, so that in each case one type of sensor is connected to a line. The sensor is very simply configured to allow unidirectional data transfer from the sensor to a controller to a controller and without resorting to bus technology. Here, the transmission is purely event-driven and runs without any complex bus protocol communication. This results in a high reliability and a low-cost and simple product. In particular, the sensors can be designed very simply with respect to their electronics.
Alle Sensoren sind also parallel an eine Schnittstellenleitung angeschlossen. Jedem Sensor ist ein bestimmtes Zeitintervall zugeordnet, zum Beispiel durch Programmierung eines Parameters im Sensor. Die Leitung ist üblicherweise als eine Zweidrahtleitung ausgeführt. Es ist jedoch möglich, sie auch als eine Eindrahtleitung auszuführen. Durch das Zuführen des ersten Energieniveaus, also dem Einschalten der Spannung oder dem Wechsel eines Spannungspegels, wird der Start zur Datenübertragung der Sensoren zum Steuergerät gegeben. Die Zeitablaufsteuerung in den Sensoren sorgt dafür, dass jeder Sensor nur in dem ihm zugewiesenen Zeitintervall seine Daten sendet. Die Zeitintervalle und die Zeiten der Datenübertragung sind dabei derart ausgelegt, dass Überschneidungen vermieden werden.All sensors are thus connected in parallel to an interface line. Each sensor is assigned a specific time interval, for example by programming a parameter in the sensor. The line is usually designed as a two-wire line. However, it is possible to make them as a single-wire line. By supplying the first energy level, ie the switching on of the voltage or the change of a voltage level, the start for the data transmission of the sensors to the control unit is given. The timing control in the sensors ensures that each sensor transmits its data only in the time interval assigned to it. The time intervals and the times of data transmission are designed such that overlaps are avoided.
Weiterhin ist es vorgesehen, dass die Sensoren Mittel zur Erkennung der Spannung oder der Spannungsänderung aufweisen, um das erste bzw. zweite Energieniveau zu erkennen.Furthermore, it is provided that the sensors have means for detecting the voltage or the voltage change in order to detect the first or second energy level.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen und Weiterbildungen sind vorteilhafte Verbesserungen des im unabhängigen Patentanspruch angegebenen Sensors möglich.The measures and refinements recited in the dependent claims advantageous improvements of the independent claim sensor are possible.
Besonders vorteilhaft ist, dass immer dem Sensor ein zweites Energieniveau zugeführt wird, das kleiner als das erste Energieniveau ist, also nicht das Signal zum Senden gibt. Dieses zweite Energieniveau, das durch eine zweite Spannung gekennzeichnet ist, sorgt dafür, dass der Sensor immer betrieben wird, also dass beim Einschalten des ersten Energieniveaus nicht ein Reset des Sensors stattfindet.It is particularly advantageous that always a second energy level is supplied to the sensor, which is smaller than the first energy level, so does not give the signal for transmission. This second energy level, which is characterized by a second voltage, ensures that the sensor is always operated, ie that when the first energy level is switched on, the sensor is not reset.

In der Fahrzeugtechnik werden Aufprallsensoren und auch Sensoren zur Erkennung der Insassenposition über Leitungen mit einem Steuergerät verbunden, das Rückhaltemittel ansteuert. Es hat sich durchgesetzt, dass diese Kommunikation häufig unidirektional abläuft, also von den Sensoren zum Steuergerät, aber nicht umgekehrt. Ein Sensor weist dabei jedoch eine einzige Leitung zum Steuergerät auf und ein zweiter Sensor eine weitere Leitung. Dies begrenzt die Anzahl der Sensoren, die an ein Steuergerät anschließbar sind. Der Begriff Leitung bezeichnet hier eine Leitung aus zwei Drähten, wobei jedoch immer auch eine Eindrahtleitung möglich ist.In vehicle technology, impact sensors and also sensors for detecting the occupant position are connected via lines to a control unit which controls restraint means. It has become established that this communication often takes place unidirectionally, ie from the sensors to the control unit, but not vice versa. However, a sensor has a single line to the controller and a second sensor another line. This limits the number of sensors that can be connected to a control unit. The term line here refers to a line of two wires, but always a single-wire line is possible.
Es wird vorgeschlagen, eine Art Quasibus zu realisieren, bei dem das Senden der Sensoren zeitgesteuert ist. Das auslösende Ereignis für die Zeitablaufsteuerung ist ein Anstieg der Energie auf der Leitung, an die die Sensoren parallel angeschlossen sind. Der erste Sensor erkennt demnach, wie auch alle anderenIt is proposed to realize a kind of quasibus in which the transmission of the sensors is time-controlled. The triggering event for the timing control is an increase in the energy on the line to which the sensors are connected in parallel. The first sensor recognizes accordingly, as well as all others
Sensoren, den Anstieg auf ein erstes Energieniveau und damit ist der Zeitpunkt gegeben, der für die Zeitablaufsteuerung maßgebend ist. Dann wird jedem Sensor ein durch seine Zeitablaufsteuerung zugeordneter Zeitschlitz gegeben, um seine Daten zum Steuergerät zu senden. Diese Zeitschlitze sind bereits herstellerseitig derart programmiert, dass sie sich nicht überschneiden. Es liegt also eine Abstimmung herstellerseitig der Sendeschlitze vor.Sensors, the rise to a first energy level and thus the time is given, which is decisive for the timing control. Then, each sensor is given a time slot assigned by its timing control to send its data to the controller. These timeslots are already programmed by the manufacturer so that they do not overlap. So there is a vote manufacturer side of the send slots.
Dann ist es möglich, dass wieder der Sensor S1 seine Daten in einem vorgegebenen Zeitintervall sendet, so dass eine zyklische Schleife zum Senden der Sensordaten vorliegt.Then it is possible that the sensor S1 again sends its data in a predetermined time interval, so that there is a cyclic loop for transmitting the sensor data.
Es ist jedoch auch möglich, dass nachdem der Sensor Sn seine Daten gesendet hat, das Steuergerät SG die Spannung auf der Leitung L wieder herunterfährt, um das Senden zu beenden. Das Ereignis, das das Senden auslöst, ist nämlich das Erhöhen der Spannung US. Dabei kann die Spannung US in einem Sprung erhöht werden, oder graduell. Überschreitet die Spannung US einen Schwellwert, wie er von den einzelnen Sensoren S1, S2 bis Sn getestet wird, dann liegt der Zeitpunkt fest, zu dem die Zeitablaufsteuerung beginnt. Die Spannung US repräsentiert ein Energieniveau, das den Sensoren S1, S2 bis Sn zugewiesen wird. In der Phase, wo auf der Leitung US nicht das Spannungsniveau gehalten wird, das das Senden der Daten veranlasst, liegt eine Ruhephasespannung U1 an, die den Betrieb der Sensoren ermöglicht, ohne dass diese ein Reset ausführen müssen, wenn sie wieder senden sollen. Sie wird, wie gesagt, für die ganze Sendephase auch auf dem erhöhten Spannungsniveau gehalten werden.However, it is also possible that after the sensor Sn has sent its data, the controller SG shuts down the voltage on the line L to stop the transmission. Namely, the event that triggers transmission is increasing the voltage US. In this case, the voltage US can be increased in one jump, or gradually. If the voltage US exceeds a threshold value, as tested by the individual sensors S1, S2 to Sn, then the time is fixed at which the timing starts. The voltage US represents an energy level assigned to the sensors S1, S2 to Sn. In the phase where the voltage level which causes the transmission of the data is not kept on the line US, there is a quiescent phase voltage U1 which allows the operation of the sensors without having to reset them when they should resend. It will be as I said, kept for the whole transmission phase and at the elevated voltage level.
In
Die Spannung kann vom Steuergerät an- und abgeschaltet werden. Dadurch kann z.B. ein Reset des Sensors ausgeführt werden. Normalerweise wird der Sensor nach dem Start des Fahrzeugs einmal durch das Steuergerät eingeschaltet (Spannung auf US) und bleibt dann an, bis die Zündung wieder ausgeschaltet wird.The voltage can be switched on and off by the control unit. Thereby, e.g. a reset of the sensor can be performed. Normally, once the vehicle is started, the sensor is turned on once by the controller (voltage to US) and then remains on until the ignition is turned off again.
Dann wird die Spannung auf den Wert U1 angehoben, der noch nicht das Senden der Sensoren S1, S2 bis Sn auslöst, aber sie mit genügend Energie versorgt, ohne dass sie, wenn sie senden sollen, ein Reset ausführen müssen. Schließlich wird die Spannung US auf den Wert U2 angehoben, und zwar für einen vorgegebenen Zeitabschnitt. In diesem Zeitabschnitt senden die einzelnen Sensoren S1 bis Sn in den Zeitabschnitten Ts1, Ts2 bis Tsn ihre Daten S1, S2 bis Sn. Nach diesem Zeitabschnitt senkt das Steuergerät SG die Spannung US auf den Wert U1 wieder ab, um ihn dann wieder auf den Wert U2 anzuheben, so dass dann der Sendezyklus erneut beginnt.Then, the voltage is raised to the value U1, which does not yet trigger the transmission of the sensors S1, S2 to Sn, but supplies them with sufficient energy without having to reset them when they are to transmit. Finally, the voltage US is raised to the value U2 for a predetermined period of time. In this period, the individual sensors S1 to Sn in the time sections Ts1, Ts2 to Tsn send their data S1, S2 to Sn. After this period, the control unit SG lowers the voltage US to the value U1 again, and then raise it again to the value U2, so that then the transmission cycle starts again.
Es ist vorgesehen, dass die Spannung US auf der Spannung U2 verharrt und zyklisch die Sensoren ihre Daten versenden. It is provided that the voltage US remains at the voltage U2 and cyclically send the sensors their data.
