Application: Virtual engine sound generating system and method using engine vibration simulated signal (Patent ID: US20240212664A1)
The patent filed by Hyundai Mobis Co Ltd. describes a system and method for generating a virtual engine sound using an engine vibration simulated signal based on driving-related information without the need for mounting an acceleration sensor on the engine. The system includes components such as an information input unit, signal generation unit, and output control unit to provide a natural engine sound output according to the vehicle's engine output torque. The method involves steps such as information input, signal generation, and output control to generate and control the virtual engine sound output through an active sound design (ASD) function and engine sound by engine vibration (ESEV) function.
The virtual engine sound generating system and method utilize driving-related information such as vehicle speed, engine RPM, and accelerator pedal sensor sensing information to control the output size of the virtual engine sound. Additionally, a model generation unit applies a conditional GAN (cGAN) algorithm to generate a generation model that outputs the vibration simulated signal based on the driving-related information and a random number. The learning processing unit controls the generation unit and classification unit to perform adversarial iterative learning, ensuring the generation of accurate vibration simulated signals for a realistic virtual engine sound output. Overall, the system and method provide a sophisticated approach to generating engine vibration simulated signals for controlling virtual engine sounds in vehicles without the need for physical acceleration sensors on the engine.
