Adaptive Pseudo Engine Sound Control for Driver Biometric Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Some drivers of battery electric vehicles are not satisfied with the pseudo engine sound, which affects their driving experience, especially when simulating a manual transmission vehicle.
Innovation Solution
A control device that includes processors to generate and adjust a pseudo engine sound based on driver preference information and biometric data, such as heart rate, to enhance the driving experience by simulating a manual transmission vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed pseudo engine sound is used in battery electric vehicles with manual transmission mode, then the system complexity is low, but the driver excitement and satisfaction are insufficient
Solution Approach 1:
The pseudo engine sound is made dynamically adjustable based on driver state. The system transitions from a fixed sound to a variable sound that adapts to the driver's biometric information (heart rate, skin conductance) and preference settings, thereby increasing driver satisfaction without requiring a complete redesign of the audio system
Solution Approach 2:
The tone parameters of the pseudo engine sound are changed based on driver state. The system modifies sound characteristics (tone, frequency, intensity) according to biometric data and driver preferences stored in the preference information storage unit, enabling adaptability while using the existing sound generation hardware
2Adaptability or versatility
If biometric sensors and preference storage are added to adjust pseudo engine sound, then driver excitement increases, but the device complexity increases
Solution Approach 1:
The control device performs multiple functions: it generates the pseudo engine sound, stores driver preference information, processes biometric data from sensors, and adjusts sound parameters accordingly. By consolidating these functions in a single control device, the system achieves high adaptability while managing complexity through functional integration
Solution Approach 2:
The system uses the vehicle's existing sensors (already present for other monitoring purposes) to collect biometric data, and stores driver preferences in dedicated memory. The control device automatically processes this data and adjusts the sound without requiring additional external systems, thereby increasing driver excitement while limiting complexity growth
Data Source
AI summary
The control device acquires biometric information of the driver by using a sensor mounted on the driver or a sensor mounted on battery electric vehicle. Further, the control device performs tone control for changing the tone of the pseudo engine sound based on the information of the preference of the driver or the biometric information.
