Patent number: 9928027Abstract: Methods and systems are provided for dynamic sound enhancement for a mobile platform. The system comprises a memory for storing a plurality of unique sound profiles, and a processor communicatively coupled to the memory. The processor receives an identification (ID) for the mobile platform, a driving mode, and references the memory using the ID and driving mode to select a sound profile. The processor also receives sail status data and engine status data for the engine, which indicates whether the engine is in sail mode or not, and the progression of the mobile platform within sail mode. Responsive to the sail status and engine status data, and in accordance with the selected sound profile, the processor generates commands for an audio system coupled to the mobile platform.Type: GrantFiled: February 8, 2017Date of Patent: March 27, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Frank C.
