A Active Noise Cancellation Cabin ANC systems provide a significantly quieter and more enjoyable driving experience by capturing and actively canceling noise in the vehicle cabin. In addition, ANC systems can enable increased fuel economy by reducing the weight of the existing metal, glass and other materials needed to reduce cabin noise. Associated hardware: • • • • MEMS Microphones A/D Converters DSPs Amplifiers D Emergency Call Emergency call systems are designed to save lives by enabling fast response to automobile accidents. In the event of an accident, the system initiates a call to emergency services, immediately shares GPS details of vehicle location, and establishes a voice connection between the occupants and emergency service personnel. Associated hardware: • • • A B Voice Recognition B C Ethernet AVB Accurate voice recognition enhances vehicle safety and convenience. It enables drivers to remain focused on the road ahead while making adjustments to in-vehicle systems while providing high-fidelity hands free communication via mobile phone. Next generation systems require higher sample rates to provide optimized handset compatibility and communication with cloud-based services.
