Abstract: A processing unit for an audio system of a vehicle comprises a first processing node, a second processing node and a program memory. The program memory may be overwritten by the first processing node and by the second processing node. After the processing unit has started up the first processing node may compute and write to the program memory an audio output. The processing unit may also perform a handover of the computing of the audio output from the first processing node to the second processing node when the first processing node has overwritten the program memory up to a predefined point and when the second processing node is operational. The second processing node is designed to compute the audio output after the handover, and to write this audio output to the program memory.

Abstract: Data compression is continuously optimized using frequency-based dictionary lookup tables for communication between a transmitter in a vehicle and a receiver. In a transmitter, first and second frequency-based dictionary lookup tables are provided. The transmitter receives a data block and compresses it using the first table. Using the data block, the second table is updated and a difference between a compression efficiency of the first table and a compression efficiency of the second table for the data block is calculated. The compressed data block is transmitted to the receiver. When the difference is more than a pre-defined threshold, the content of the first table is replaced with the content of the updated second table in the transmitter. The content of the updated second table is then also transmitted to the receiver.

Abstract: Subjects of the present disclosure are methods for training deep learning models, methods for predicting a map matching parameter, methods for updating a digital road map, and a computer program making it possible to implement the methods and devices for updating a digital road map. The general principle is based on the use of machine learning. Accordingly, a statistical deep learning model is trained according to a “supervised” machine learning scheme. Thereafter, the pretrained statistical deep learning model is used to predict a map matching parameter on the basis of a measurement of geographic coordinates and of an identifier of the position sensor that has performed the measurement of geographic coordinates. Finally, the map matching parameter can be used to update a digital road map.
