Title: The Innovations of Osamu Maeda

Introduction

Osamu Maeda is a notable inventor based in Iwata, Japan. He has made significant contributions to the field of sound signal generation, particularly in relation to electric vehicles. With a total of 10 patents, his work focuses on creating realistic engine sounds for electric vehicles, enhancing the driving experience.

Latest Patents

Maeda's latest patents include a sound signal generation device, sound signal generation method, and sound signal generation program. These inventions aim to provide a sound signal generation device capable of artificially generating an engine sound signal that mimics a realistic engine sound linked to the running of an electric vehicle, even when an engine is not mounted. The device features a virtual engine rotation speed generation unit that acquires accelerator opening data and running speed data, calculates a virtual running speed, and modifies it based on the running speed data. Additionally, an artificial engine sound generation unit generates a sound signal for outputting an artificial engine sound corresponding to the running state of the electric vehicle based on the accelerator operation amount.

Another of his recent patents is a sound pressure signal output apparatus, sound pressure signal output method, and program for sound pressure signal output. This invention synthesizes and outputs a sound pressure signal that simulates the sound of a real engine with reduced processing load in real time. The apparatus includes an interface that acquires sound data corresponding to the sound generated by one cylinder of a vehicle-mounted internal combustion engine during one combustion cycle, as well as order sound data and random sound data. A synthesis unit then combines these data to produce the engine sound.
