METHOD FOR IDENTIFYING SENSORS ON A BUS BY A CONTROL UNIT, AS WELL AS A CONTROL UNIT AND A SENSOR FOR DOING THIS
First Claim
Patent Images
1. A method for identifying sensors on a bus by using a control unit, the method comprising:
- sending, using at least one first sensor and one second sensor, physical useful data to the control unit via the bus, the physical useful data being evaluated by the control unit for the control of a function;
comparing the physical useful data of the first sensor and of the second sensor to at least one of (i) one another and (ii) specified expected values; and
identifying the first sensor and the second sensor by using the control unit with the aid of the comparison and based on characteristic differences in the physical useful data of the first sensor and the second sensor.

Abstract
A method for identifying sensors on a bus by a control unit, as well as a control unit and a sensor for doing this. The sensors, in this instance, send physical useful data to the control unit as the basis for the control of a function. Furthermore, the physical useful data are compared to one another and/or to specified expected values, and the identification of the sensors by the control unit takes place with the aid of the comparison and based on characteristic differences in the physical useful data for the sensors.

9. A control unit, comprising:
-
a receiving arrangement to receive physical useful data via a bus from at least one first sensor and one second sensor; an evaluating arrangement to evaluate the physical useful data for the control of a function; and an identifying arrangement to identify the first sensor and the second sensor with the aid of a comparison of the physical useful data of the first sensor and of the second sensor to at least one of one another and specified expected values and based on characteristic differences in the physical useful data for the first sensor and the second sensor. - View Dependent Claims (10)

11. A sensor to send physical useful data to a control unit via a bus, the physical useful data being evaluated by the control unit for the control of a function, comprising:
-
a comparing arrangement to compare the physical useful data to specified expected values, so as to provide a comparison; and a control arrangement to allow the sending of the physical useful data to the control unit to take place at a point in time that is determined by the comparison.
