In order to process sensor data for a driver assistance system oriented towards the driver's comfort, sensor data that is sensed by a sensor device and describes objects is preprocessed such that a distinction is made between a driving zone and a non-driving zone, where the driving zone is designated as an object driving zone. The object driving zone is delimited by a boundary line. Since the sensor data is processed for a comfort-oriented driver assistance system, it does not have to describe the entire theoretical driving zone. Rather, the boundary line is used to delimit the driving zone within which the vehicle can normally be expected to drive. Based thereon, it is easy to determine an appropriate boundary line and significantly reduce the volume of data to be transmitted from the sensor device to a central control device of the comfort-oriented driver assistance system in order to describe the sensed objects.

Processing of sensor data for a driver assistance system

A driver assistance system for a motor vehicle has a controller within a speed and/or distance regulator, which controller is used for the regulation of the acceleration of the motor vehicle according to a setpoint acceleration. The driver assistance system also includes an input coupling unit for coupling an additional acceleration that can be predefined by the driver of the motor vehicle into the system.

Driver assistance system for a motor vehicle

A communication device for a motor vehicle includes a first control unit (BDC), a second control unit (SAS), a control unit arrangement (SGA), a first data bus (SB), to which the first control unit (BDC) and the control unit arrangement (SGA) are connected for the exchange of data, as well as a second data bus (AB), to which the second control unit (SAS) and the control unit arrangement (SGA) are connected for the exchange of data. The control unit arrangement includes at least a first sensor control unit (SSG) for controlling a first sensor and a second sensor control unit (SSG) for controlling a second sensor. The first and the second sensor have mutually overlapping sensor acquisition ranges. The first and the second sensor control unit can exchange at least preprocessed sensor data by way of a third data bus (PB). The first and the second sensor control unit are constructed to be operated in a master-slave operation with respect to at least one functionality. By way of the first sensor control unit as the master of a first functionality (F), first data (DFC), which are provided by the first control unit at the first data bus, are processed for the control unit arrangement. By way of the second sensor control unit as the master of a second functionality (F), first application data (AD) for the second control unit are provided at the second data bus.
