AI Technical Summary
⚠Technical Problem
Existing technologies struggle to generate a pseudo-engine sound that effectively emphasizes rapid changes in engine speed, leading to discomfort for drivers and reduced awareness among traffic participants.
⚗Method used
A control device that generates a pseudo-engine sound by increasing the sound volume or intensity when the engine speed changes rapidly, utilizing a combination of NE-based, AP-based, and ΔNE/sec controls to simulate engine sounds in hybrid electric vehicles, enhancing the driving experience and visibility.
🎯Benefits of technology
The solution provides a realistic simulation of engine sound changes, improving driver comfort and traffic awareness by emphasizing engine speed variations, particularly in hybrid driving modes.

Abstract
A control device (20) for controlling a vehicle (10) provided with a first motor generator (MG1) that is mechanically connected to drive wheels (DWs) which are output units for outputting a drive force, and an engine (ENG) which is a prime mover, the control device executing first sound generation control for generating a pseudo engine sound from the vehicle (10) when the engine rotation speed changes by a prescribed rotation speed or more per unit time, or making the pseudo engine sound to be generated louder compared to when the engine rotation speed does not change by the prescribed rotation speed or more per unit time.
