Abstract: A simulation device and method for a surroundings sensor system configured to detect at least one particular object based on a respective signal echo. A receiving device configured to receive a first signal that is sent from the surroundings sensor system and to convert it into a first operating signal. A signal path that is connected to the receiving device for accepting the first operating signal, the signal path being configured to generate, via a first signal processing, a second operating signal that is a function of the first operating signal and the respective signal echo. The respective signal echo being characterized by at least one signal parameter. A second signal processing being provided to provide the at least one signal parameter with a variation. A transmitting device configured to convert the second operating signal into a second signal and to send the second signal to the surroundings sensor system.

Abstract: A testing system of a radar sensor for an active environment sensing system includes: a first target simulator, comprising: a first electronic control unit; a first receive antenna, connected to the first electronic control unit, for receiving a radar sensor signal; and a first transmit antenna, connected to the first electronic control unit, for emitting a first radar echo generated by the first electronic control unit; and a second target simulator, comprising: a second electronic control unit; a second receive antenna, connected to the second electronic control unit, for receiving a radar sensor signal; and a second transmit antenna, connected to the second electronic control unit, for emitting a second radar echo generated by the second electronic control unit.

Abstract: A method for modular manufacturing of a car body shell of a rail vehicle includes manufacturing at least two directly adjoining large assemblies of the car body shell in parallel. The large assemblies are selected from among the group including an underframe, a side wall, a roof, an end wall, and a head of the body. The at least two large assemblies manufactured in parallel as described above are joined by structural adhesive bonding. A car body shell of a rail vehicle manufactured by the method is also provided.
