Cloud-Based AM Radio Access for Electric Vehicle Infotainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles often interfere with AM radio frequencies due to components like electric motors, making it difficult for traditional AM radio tuners to receive radio content effectively.
Innovation Solution
A vehicle infotainment system utilizing a vehicle entertainment support (VES) server and a digital AM radio module, which communicates via wireless protocols like cellular, Wi-Fi, and V2X to obtain and transmit AM radio content from external sources without a physical AM tuner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional AM radio tuner is used in an electric vehicle, then AM radio content can be received, but the electric vehicle components (electric motors) interfere with AM radio frequencies causing poor reception quality
Solution Approach 1:
The patent introduces a cloud-based VES server as an intermediary between the electric vehicle and AM radio stations. The server receives AM radio content from traditional tuners, processes it, and transmits it to the vehicle via wireless protocols (cellular, Wi-Fi, V2X), eliminating the need for a physical AM tuner in the vehicle and thus avoiding interference from electric motor components
Solution Approach 2:
The patent replaces the mechanical/electromagnetic AM radio tuner system with a digital wireless communication system. Instead of using a physical tuner that directly processes AM signals and is susceptible to electromagnetic interference from electric motors, the system uses digital wireless protocols to transmit radio content, substituting the mechanical reception system with a digital communication approach
2Ease of operation
If a physical AM tuner is installed in the vehicle, then AM radio content can be received directly, but the vehicle structure and components become more complex and susceptible to interference
Solution Approach 1:
The patent extracts the AM radio reception functionality from the vehicle itself and relocates it to a cloud-based VES server. The vehicle only needs basic wireless communication capabilities and a digital AM radio module, eliminating the need for a physical AM tuner and its associated complexity within the vehicle structure
Solution Approach 2:
The VES server provides universal access to AM radio content through multiple wireless protocols (cellular, Wi-Fi, V2X), making the system adaptable to different vehicle types and communication standards. This multi-functional approach allows any vehicle with basic wireless capability to access AM radio content without requiring vehicle-specific hardware modifications

AI summary
A system, for providing radio content to a vehicle, includes a vehicle communication system, a vehicle infotainment system, and a vehicle entertainment support server remote from the vehicle. The vehicle communication system includes a tuner unresponsive to a first radio transmission medium and is configured to transmit a radio content request requesting radio content from an identified radio station (i.e., a desired radio station). The vehicle infotainment system configured to obtain an input identifying the desired radio station broadcasting in the first radio transmission medium and emit radio content from the desired radio station. The vehicle entertainment support server remote is configured to: receive radio content from a source, store the radio content in a selected staging memory; obtain the radio content request; and transmit the radio content in the selected staging memory in response to the transmitting radio station being the desired radio station in radio content request.
