Abstract: A method for operating radar sensors in a vehicle. At the outset, the acquired targets are divided into stationary targets and moving targets. The moving targets are then divided into primary targets, whereof the distances from the vehicle are less than a pre-definable threshold value, and secondary targets, whereof the distances from the vehicle are greater than a threshold value. The primary targets are fed to a first tracking device, which ascertains the states of the primary targets. The secondary targets are fed to a second tracking device, which ascertains the states of the secondary targets. The second tracking device carries out a computationally less powerful ascertainment of the states than the first tracking device.

Abstract: The present invention relates to a control of a DC converter (10) comprising a plurality of DC converter modules (4-1, 4-2). For this purpose, a central control variable is generated for all DC converter modules for a voltage-controlled control of the DC converter. Moreover, a current-based control variable can additionally be generated for each DC converter module. The output power, in particular the output current of each DC converter module can be individually adjusted by combining the voltage-based control variable and the current-based control variable. An overload of the DC converter modules can thus be prevented.
