Pseudo Driving Sound Playback for Multi-Model Vehicle Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pseudo driving sound systems primarily focus on outputting driving sounds to the outside and require high accuracy in detecting the driving state of electric vehicles, making them costly and limiting user experience to a single vehicle model.
Innovation Solution
A pseudo driving sound playback system comprising a server and an in-vehicle device that stores and outputs pseudo sound data sets for multiple passenger gasoline vehicle models, allowing users to select and experience different models based on detected driving states, with optional virtual environmental sounds and customizable settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high accuracy detection configuration is used to ensure driving sound accuracy, then driving sound accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses audio recording and playback technology to copy actual driving sounds from multiple vehicle models and store them in a database. Instead of using complex detection systems to generate sounds in real-time, the system records actual engine sounds, exhaust sounds, and environmental sounds from different vehicle models and plays back the appropriate pre-recorded sounds based on simple parameter matching (vehicle model, speed, acceleration). This copying approach maintains high driving sound accuracy while avoiding complex detection and generation systems.
2Adaptability or versatility
If multiple vehicle models are supported, then user experience versatility is improved, but system complexity increases
Solution Approach 1:
The patent segments the driving sound system into distinct modular components: a database storing pre-recorded sounds for multiple vehicle models, a detection unit that simply identifies current vehicle parameters (model, speed, acceleration), and a playback control unit that selects and plays the appropriate sound segment. Each vehicle model's sounds are stored as separate segments in the database, allowing easy addition of new models without increasing system complexity. The segmentation enables the system to support multiple vehicle models while maintaining simple architecture.
Solution Approach 2:
The playback control unit serves multiple functions: it detects vehicle parameters, queries the database for matching sounds, selects the appropriate sound segment, and controls playback. This multi-functional design allows the system to support multiple vehicle models using a single unified control mechanism, avoiding the need for separate systems for each model and thereby reducing overall system complexity while maintaining versatility.
3Productivity
If real-time sound playback is implemented, then driving experience immersion is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic sound playback rather than continuous generation. The playback control unit monitors vehicle parameters and triggers sound playback only when parameter changes occur (e.g., acceleration changes, speed changes, gear shifts). Between parameter changes, the system remains in a low-power state. This periodic action maintains immersive driving experience by providing sounds at appropriate moments while significantly reducing energy consumption compared to continuous real-time sound generation.
Data Source
AI summary
A pseudo driving sound playback system includes a server and an in-vehicle device. The server includes a database of pseudo sound data sets in which sound elements of engine sound are associated with each of a plurality of predefined driving states for each of a plurality of passenger gasoline vehicle models. The in-vehicle device determines one of a plurality of vehicle models based on received input of a user, downloads a pseudo sound data set of the vehicle model from the server, selects a sound element according to the detected driving state from the pseudo sound data set, and sequentially outputs the sound element as sound from a speaker.
