First Claim
1. A sensor transmitter device for transmitting payload data of a sensor to a bus control device and being connectable to a data bus of a vehicle, the data bus being configured for simultaneous transmission of bus data packets between a plurality of sensor transmitter devices and a bus control device, comprising:
- a sensor interface to receive payload data which represent a physical quantity, wherein each of the bus data packets include at least one signaling field and one payload data field having a plurality of payload data blocks;
a memory configured for storing position information which identifies at least one payload data block from the payload data field, which is reserved exclusively for the transmission of payload data from the sensor transmitter device to the bus control device; and
a bus interface configured for placing, after receiving predetermined signaling data in the signaling field, at least part of the payload data received via the sensor interface in the payload data block specified by the position information.

Abstract
A sensor transmitter device for transmitting the payload data of a sensor to a bus control device is described, the sensor transmitter device being connectable to a data bus of a vehicle, which is configured for simultaneous transmission of bus data packets between a plurality of sensor transmitter devices and a bus control device. The bus data packets should include at least one signaling field and one payload data field having a plurality of payload data blocks. The sensor transmitter device includes a sensor interface for receiving payload data which represent a physical variable and a memory which is configured for storing position information which identifies at least one payload data block from the payload data field, which is reserved exclusively for the transmission of payload data from the sensor transmitter device to the bus control device. The sensor transmitter device also includes a bus interface which is configured for placing, after receiving predetermined signaling data in the signaling field, at least part of the payload data received via the sensor interface in the payload data block specified by the position information.
