Remote Engine Revving Control for User-Triggered Sound Emission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems require manual input to rev the engine, limiting the ability to control engine sound remotely and decreasing the appeal of electric vehicles to performance enthusiasts, as they lack the engine sound associated with traditional vehicles.
Innovation Solution
A method to remotely rev a vehicle engine to a peak speed using a user-controlled input device, without manual depression of the accelerator pedal, by adjusting engine speed and exhaust tuning valve to produce a desired sound, utilizing existing engine and audio architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input is required to rev the engine, then the engine can be controlled directly by the user, but the process requires time and effort for the user to enter the vehicle and operate the accelerator pedal
Solution Approach 1:
The patent replaces the mechanical operation of pressing the accelerator pedal with an electronic remote control system. The remote control device transmits signals wirelessly to the vehicle's control unit, which then actuates the throttle body electronically to rev the engine, eliminating the need for manual physical interaction with the vehicle.
Solution Approach 2:
The patent introduces a remote control device as an intermediary between the user and the engine control system. This intermediary communicates with the vehicle's control unit through wireless signals, enabling the user to control engine revving from a distance without direct physical contact with the vehicle.
2Adaptability or versatility
If electric vehicles are used to reduce fossil fuel reliance, then environmental benefits are achieved, but the engine sound and revving experience is lost
Solution Approach 1:
The patent creates a copy of the engine revving experience by using the existing audio architecture to generate and amplify artificial engine sounds. The system plays back recorded or synthesized engine revving sounds through the vehicle's audio system, providing the characteristic engine noise experience without actual combustion engine operation.
Solution Approach 2:
The patent makes the audio architecture serve multiple functions: it acts as both the vehicle's normal audio/entertainment system and as an engine sound generation system. By programming the existing speakers and audio processing components to generate engine revving sounds, the system eliminates the need for separate dedicated hardware while providing the desired effect.
3Ease of operation
If remote engine revving is implemented, then the ability to control engine sound from a distance is achieved, but the system complexity may increase
Solution Approach 1:
The patent leverages existing multi-functional components in the vehicle, particularly the audio architecture and control unit, to implement remote engine revving. By programming the existing control unit to handle remote revving commands and using the audio system for sound generation, the patent avoids adding dedicated new hardware while achieving the desired functionality.
Solution Approach 2:
The patent enables the existing control unit and audio system to serve the additional function of remote engine revving without requiring separate dedicated systems. The control unit processes remote commands and the audio system generates sounds, allowing these components to self-extend their functionality through software programming rather than hardware addition.

AI summary
Methods and systems are provided for user controlled engine revving. In one example, the engine may be revved to a peak speed according to a target revving sequence in response to a user-initiated command. A revving sound may be provided in response to an input device, without demanding manual depression of an accelerator pedal.
