Definitions
- the invention relates to a variable sensor interface for a control device, comprising a printed circuit board for connecting at least one external sensor, which is equipped with components.
- automotive engineering control devices which receive signals from a plurality of sensors, which are arranged distributed in motor vehicles. These sensors are routed within the control unit to a sensor interface. From the
- DE 10 2006 046 834 A1 discloses a control unit in a steering system of a vehicle, which is connected to determine a steering angle with a magnetic field sensor which determines the rotor position of the rotor shaft of an electric motor.
- control unit is connected not only with a sensor but with different sensor types, which require different interface circuits.
- interface circuits may be, for example, a current interface, a PWM interface, an analog interface and the like.
- passive and active sensors are connected. This diversity of sensor types requires that for each sensor type a fixedly defined sensor interface must be maintained, which is installed in the control unit. Due to this large number of sensors, the interface must be prepared specifically for the sensors to be connected, which greatly increases the number of sensor interfaces to be provided.
- the invention is therefore based on the object to provide a sensor interface for a control unit, to which the different sensor types are easily connectable.
- the object is achieved in that the printed circuit board has a printed circuit board layout with a multiplicity of predetermined placement locations for components, wherein the placement sites can be equipped with components in a sensor-specific manner.
- Such flexibility allows various configurations of sensors to be connected to a controller without the need to change a fixed trace layout.
- the provision of different interfaces for the respective sensor types can thus be dispensed with, since the variable sensor interface can be varied by simply equipping selected placement locations with components. This limits the variety of interfaces and reduces manufacturing costs.
- sensor-specific, a predetermined number of resistors and / or capacitors can be connected to different placement locations. This variable sensor interface thus provides a circuit through the provision of mounting options for the resistors and capacitors, with minimal effort and without
- Circuit board layout changes of the circuit board is suitable for a wide variety of sensor types.
- a protection circuit for transient disturbances and / or ESD can be connected to at least one mounting location sensor-specific.
- an overcurrent protection circuit can be connected to at least one of the placement locations. Such an overcurrent protection circuit limits the current in the event of a short circuit and protects the control unit against damage.
- the overcurrent protection circuit is in one or more
- a development of the invention relates to a control device for a motor vehicle, which is connectable to at least one external sensor by the external sensor is connected to a sensor interface.
- the sensor interface is formed according to at least one feature of this patent application.
- Such a control unit is intended for the connection of different sensor types. It is particularly advantageous that the sensor interface can be configured depending on the sensor type, without having to make a Portererbahnlayout selectedung the circuit board of the sensor interface.
- each input or output of the sensor interface with a

- the control unit 1 shows a first embodiment of a control unit 1 is shown, as used for example in a motor vehicle.
- the control unit 1 has two outputs 2, 3 for the power supply of external sensors, which are not shown.
- the output 2 is connected to a first protection circuit 4 for transient disturbances and ESD, which is connected in series with a first overcurrent protection circuit 5.
- This overcurrent protection circuit 5 is connected via a first resistor R1 to a first voltage source 6 of the control unit 1.
- the overcurrent protection circuit 5 limits the current of the supply voltage 6 at the output 2 in the event of a short circuit and thus prevents damage to the control unit 1.
- the second output 3 of the control unit 1 is connected via a second protection circuit 7 for transient disturbances and ESD, which leads to a second overcurrent protection circuit 8.
- This second overcurrent protection circuit 8 is connected via the resistor R2 to a second voltage source 9 of the control unit 1.
- a third resistor R3 is arranged between the first overcurrent protection circuit 5 and the first resistor R1 and the second overcurrent protection circuit 8 and the second resistor R2.
- a third resistor R3 is arranged.
- About the placement options of the resistors R1, R2 and R3 can be the two supply voltages 6, 9 of the control unit 1 arbitrarily for the two outputs 2, 3 combine. This is shown in more detail in Table 1. Table 1
- not equipped should be understood to mean an interruption in the conductor layout 17. If the resistance is 0 ohms, a resistance bridge is present in the trace layout 17.
- FIG. 2 shows a second embodiment of a control unit 10, which holds two inputs 1 1, 12 for the external sensor in addition to the output 2 for an external sensor.
- the output 2 is connected to the voltage source 6 via the first protection circuit 4 for transient disturbances and ESD and via the first overcurrent protection circuit 5.
- a second and a third protection circuit 13, 14 for transient disturbances and ESD is connected to the inputs 1 1 and 12 respectively.
- the second transient noise protection circuit 13 passes through a resistor R5 and a filter resistor R Fi he t to an internal input 15 of the control unit 10 to which a not shown analog / digital converter may be connected to either or a digital PWM input is connected.
- the filter resistance R F he iit is iiter connected to ground via a capacitor C F.
- the second protection circuit 13 for transient disturbances and ESD is connected via a resistor R6 and the third protection circuit 14 for transient disturbances and ESD via a resistor R7 to an overcurrent protection circuit 16, which in turn leads

- t he and the filter capacitor C F may be omitted iiter.
- the resistors R4 to R7 represent equipment options. Depending after application, however, the value of the filter resistor R F is iit he or adapt the filter capacitor C F iiter what happens as a function of the rate of change of the sensor signal. Table 2 shows the possible interface types which are realized by the different equipping with the resistors R4 to R7.
- R4 is a reference resistor.
- the voltage supply from the external sensor is connected to output 2 and input 12.
- Input 1 1 is used as input for the sensor signal and R4 is designed as a pull-up resistor.
- the external sensor is designed as a passive speed-inductive sensor, the terminals of the external sensor to the inputs 1 1 and 12.
- the output 2 remains open, while the resistors R4 and R5 serve to provide the signal with an offset to to be able to feed it to an analog / digital converter at the inner input 15. This ensures that the sensor signal is always in the positive voltage range.
- the external sensor connected to the control unit has an analogue voltage, the voltage supply of the external sensor is provided by the output 2 and the input 12.
- the input 1 1 is the input for the sensor signal
- the voltage supply of the external sensor is connected to output 2 and input 12.
- Input 1 1 is the input of the sensor signal and resistor R6 is a current / voltage converter resistor.
- the illustrated variable interface is suitable for any type of controller where the connection of various sensors is provided.
- the particular advantage is that the circuit adapted to the respective external sensor is necessary without a printed circuit board layout change of the printed circuit board, but only fitting by resistors has to be adapted.
