Device and method for determining the sensor position of sensor units of a driver assistance system
First Claim
1. A device for determining sensor positions of sensor units of a driver assistance system of a motor vehicle, the device comprising:
- a plurality of sensor units disposed for monitoring purposes on the motor vehicle;
a central control and evaluation unit; and
a data bus connecting said sensor units to said central control and evaluation unit for an exchange of data;
each of said sensor units having a plurality of terminals of different identification positions, at least one of said terminals connected to said data bus, with a connection scheme of said data bus with said at least one terminal providing an identity code for a sensor position of a respective sensor unit.

Abstract
A device and a method determine sensor positions of sensor units of a driver assistance system, especially a parking aid system of a vehicle. The sensor units each have a plurality of terminals of different identification positions. A data bus is connected for an exchange of data with a central control and evaluation unit in this case with one or more terminals of the sensor unit according to a specific connection scheme, which is different for each of the sensor units, in order to provide an identity code for the sensor position of a sensor unit in this way.

3. A device for determining a sensor position of a sensor unit of a driver assistance system of a motor vehicle, the device comprising:
-
a plurality of sensor units disposed for monitoring purposes on the motor vehicle and each having a data input and a data output, with said data input being activated and said data output deactivated in an initial state; a data bus connecting said sensor units to each other in series so that said data output of one of said sensor units is connected to said data input of a following one of said sensor units; and a central control and evaluation unit connected for an exchange of data over said data bus to individual ones of said sensor units, said central control and evaluation unit allocating a respective sensor unit a new individual identity code and said respective sensor unit activating said data output for a data connection to a next one of said sensor units being a next sensor unit. - View Dependent Claims (4, 5, 6, 7, 8, 9)

13. A method for determining a sensor position of sensor units of a driver assistance system of a vehicle, which comprises the steps of:
-
connecting the sensor units in series with each other and with a central control and evaluation unit for an exchange of data, with a passage of the data through a sensor unit being blocked in an initial state; identifying a respective sensor unit by allocation of a new individual identity code to the respective sensor unit by the central control and evaluation unit; and canceling a blocking of the passage of the data of an identified sensor unit to create a data connection to a next sensor unit. - View Dependent Claims (14, 15, 16)
