Solution Overview
Problem
Existing electric vehicles (EVs) lack the ability to emulate the performance metrics, sounds, and feels of combustion engine vehicles, such as torque curves, vibrations, and engine sounds, which are significant aspects appreciated by consumers.
Innovation Solution
A vehicle emulation profile system that allows users to purchase and load emulation profiles onto their EVs, replicating the operational characteristics of petrol-based vehicles, including torque curves, vibrations, and sounds, through a vehicle infotainment system or mobile app, using processing circuitry to align the EV's operational capabilities with those of petrol-based vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If EVs are designed with electric powertrains, then energy efficiency and environmental performance are improved, but the characteristic performance metrics, sounds, and feels of combustion engine vehicles are lost
Solution Approach 1:
The patent creates virtual copies of combustion engine vehicles through detailed 3D models that replicate exterior dimensions, interior layouts, and operational characteristics. These digital twins allow EVs to emulate the performance metrics, sounds, and feels of petrol-based vehicles without physical modifications, resolving the contradiction between energy efficiency and emulation capability.
Solution Approach 2:
The system dynamically adjusts operational parameters such as acceleration rates, top speeds, and audio outputs to match those of combustion engine vehicles. By changing these parameters in real-time, the EV can emulate different vehicle characteristics while maintaining its electric powertrain's energy efficiency.
2Ease of operation
If EVs emulate combustion engine vehicles through software profiles, then user experience is enhanced, but system complexity increases
Solution Approach 1:
The patent implements a universal emulation platform that can replicate multiple combustion engine vehicle types through a single system architecture. The platform uses standardized 3D modeling techniques and parameter adjustment mechanisms that work across different vehicle models, reducing the complexity that would otherwise arise from implementing separate emulation systems for each vehicle type.
Solution Approach 2:
The patent replaces physical mechanical systems with software-based solutions. Instead of modifying actual engine components to change performance characteristics, the system uses virtual profiles and digital twins to emulate combustion engine behavior, significantly reducing mechanical complexity while enhancing user experience.
3Measurement precision
If detailed 3D models and operational parameters are created for emulation, then emulation accuracy is improved, but data processing requirements increase
Solution Approach 1:
The patent divides the emulation system into modular components: external 3D models for visual representation, internal 3D models for spatial relationships, and separate operational parameter sets for different vehicle characteristics. This segmentation allows the system to process only the necessary data for each emulation scenario, reducing overall energy consumption while maintaining high accuracy.
Solution Approach 2:
The system pre-processes and stores 3D model data and operational parameters in optimized formats before emulation begins. By preparing this data in advance, the system reduces real-time processing requirements during actual emulation, thereby lowering energy consumption while preserving emulation accuracy.
