9. A system for testing a control unit of a vehicle, comprising:
a computer device, which is connectible to the control unit via a vehicle data bus; and
a sensor testing unit, which is connected to the computer device and is connectible to the control unit via a sensor terminal;
wherein upon connection with a control unit for a vehicle, the system is configured to test a control unit of a vehicle, the control unit obtaining calculated surrounding-area data of at least one simulated surround sensor, using a surround-sensor simulation, and obtaining calculated motion data of a simulated vehicle, using a simulation of the vehicle and of a surrounding area, the simulation of the vehicle and surrounding area being implemented by a computer program, which is executed on the computer device, the calculated motion data being transmitted to the control unit via a simulated vehicle data bus, and using the sensor testing unit, the calculated surrounding-area data being transmitted to the control unit via a sensor-data transmission circuit different from the vehicle data bus, wherein the following steps are performed for execution of a simulated acquisition of surrounding-area data by the control unit:
a) transmitting by the control unit of a command for executing a measurement, using at least one surround sensor simulated by the surround-sensor simulation, to the sensor testing unit;
b) transmitting by the sensor testing unit data for identifying a position of the at least one simulated surround sensor, to the computer device;
c) calculating by the computer device positions of points of reflection by simulated objects in the surroundings of the vehicle, and transmitting data regarding the calculated positions of the points of reflection to the sensor testing unit;
d) determining by the sensor testing unit calculated surrounding-area data based on the data regarding the calculated positions of the points of reflection; and
e) transmitting by the sensor testing unit calculated surrounding-area data regarding the obtained positions of the points of reflection, to the control unit; and
wherein the simulation of the vehicle and surrounding area is executed continually by the computer device, and motion data of the simulated vehicle calculated regularly are transmitted to the control unit; the determination of the position of reflection points according to step c) being synchronized temporally with the simulation of the vehicle and surrounding area.
