ELECTRIC VEHICLE, CONTROL METHOD, AND RECORDING MEDIA

Smart overview of the Invention

The application presents an electric vehicle equipped with an electric motor as its drive source, featuring advanced processing circuitry. This system is designed to generate and output artificial sounds from a speaker in relation to the required torque for the vehicle's drive system. In a specific mode, the artificial sound generation is aligned with a torque requirement that operates independently from the accelerator's input. This innovation aims to enhance the driving experience by providing sound feedback that reflects the vehicle's operational state, even when traditional accelerator input is not the primary torque determinant.

Technical Context

The field of this invention is electric vehicles, specifically those using electric motors instead of traditional combustion engines. Prior art includes a vehicle control device that simulates engine sounds within a vehicle cabin, correlating with virtual engine load. This invention builds on such concepts by addressing scenarios where torque requirements may not directly correlate with accelerator input, thus improving user experience by reducing potential dissonance between vehicle operation and sound feedback.

Problem Addressed

Electric vehicles typically produce minimal driving noise, which can diminish the driving experience. Existing solutions generate artificial sounds based on accelerator input, but these do not account for situations where torque requirements differ from accelerator actions. This discrepancy can cause discomfort for the driver, as the sound feedback does not accurately represent the vehicle's driving state. The invention addresses this gap by ensuring sound output reflects actual driving conditions, even when torque is determined by factors other than the accelerator.

Solution Proposed

The proposed solution involves a system where the electric vehicle's processing circuitry can generate artificial sounds in sync with the required torque for the drive system. In a particular operational mode, the system can produce sounds that correspond to torque requirements independent of accelerator input. This ensures that the sound feedback remains consistent with the vehicle's driving state, thereby enhancing the driver's experience and minimizing discomfort from mismatched sound cues.

Benefits and Implementation

The innovation allows for the generation of artificial sounds that accurately reflect the driving state of the electric vehicle, regardless of how the required torque is derived. This is particularly beneficial in scenarios where the vehicle's control systems dictate torque independently of the accelerator. By outputting sounds that align with these conditions, the invention reduces driver discomfort and enhances the overall driving experience. The system's implementation involves integrating processing circuitry and speakers within the vehicle, ensuring seamless operation and sound output.
