An apparatus and a method for bundling two data channels via a point-to-point connection, is described herein. Sequences of data from a first data channel are transmitted via a first line and sequences of data from a second data channel are transmitted via a second line to a multiplexing apparatus. A data gap having a predefined size is arranged between two sequences of first data in each case. The data from the second data channel are transmitted to a buffer and, if the buffer has been filled with second data having a predefined size, are inserted into the data from the first data channel. A third data channel is formed at the output of the multiplexing apparatus using these first data and second data and is transmitted to a third line. The third data channel therefore has a bundling of sequences of first data and sequences of second data.

Abrégé
The invention relates to an ADAS sensor data processing unit (40, 28, 58, 70), to an ADAS sensor system (30; 200, 24; 500, 54; 60) and to an ADAS sensor data evaluation method for use in driver assistance systems or systems for the automated driving of a vehicle. An ADAS sensor data processing unit (40, 28, 58, 70) according to the invention comprises an input interface (401, 281, 581, 701), a decompression module (7), a processing unit (44, 22, 55) and an output unit (400, 280, 57). The input interface (401, 281, 581, 701) is designed to receive data of an ADAS sensor (1, 14) that have been subjected to lossy compression by a compression module (6). The decompression module (7) is designed to decompress the compressed data (lcSD) of the ADAS sensor (1, 14). The processing unit (44, 22, 55) is designed to process the decompressed data (ldSD) of the ADAS sensor (1, 14), information (RI) relevant to an ADAS/AD function being ascertained from the decompressed sensor data (ldSD). The output unit (400, 280, 57) is designed to output the ascertained information (RI) relevant to the ADAS function. Advantages of using a lossy compression are a lower required amount of memory during development for the persistent storage of recorded sensor data, a lower required bandwidth for transmitting the sensor data to the computer unit and a lower bandwidth for transmitting the data within an "intelligent" ADAS sensor.

A method for determining the rotational speed and the angle of rotation of a motor shaft of a mechanically commutated DC motor from the measured progression of time of the ripple in the motor current and in the motor terminal voltage occurring during the commutation. A motor state model of the DC motor, to which the measured motor terminal voltage and the measured motor current, an estimated load torque, an estimated rotational speed and an estimated angle of rotation of the DC motor are supplied to a Kalman filter as input variables. By running the motor state model, the Kalman filter provides an estimated current, an adjusted rotational speed and an adjusted angle of rotation of the DC motor as output variables. From the ripple in the measured motor current and the rotational speed, adjusted by the Kalman filter, a ripple detection unit determines the commutation times and, from the latter, derives an estimated rotational speed and an estimated angle of rotation of the DC motor and provides same to the Kalman filter as the input variables.
