Measurement of parameters of the eCall system transmission channel for passenger car
Original language description
Emergency call system, which in the case of traffic accidents ensure rapid assistance to motorists, will be mandatory for all new passenger cars approved since 2017-2018. The speech intelligibility as one of the parameters of eCall developed for cars depends on parameters of the transmission channel. Due to the internal design and arrangement of the car interior, there are not many suitable variations of speaker location in terms of quality of speech transmission. Therefore, ITU standards provide the recommended values and measurement procedure of important parameters (eg. RLR, THD, SNR). The paper deals with methods of measurement RLR, THD and SNR parameters inside the car. Measuring methods were verified by measurements in a car available on the University of West Bohemia. Measurements were performed by using the artificial head in different positions in the driver seat. The speaker of eCall was placed in several positions. Parameters were measured for different operating conditions (driving at different speeds, different settings for internal air circulation). From the measurement results, it is possible to determine the influence of speaker location and the position of the artificial head.
