In addition to the wide range of series applications, the CAN multi-sound module also offers numerous advantages in the development of new systems. It is used in test vehicles from Knorr- Bremse Systeme für Nutzfahrzeuge GmbH, which are unable to provide qualified feedback due to the lack of dashboards. In the test phase, the multi-sound module acoustically reproduces warning messages, such as the signal from an emergency brake assistant, in the cockpit. The possibility of assigning parameters yourself according to the requirements enables the rapid implementation of different application scenarios.
