Document Type and Number:
Japanese Patent JP7199133
Kind Code:
B2
Abstract:
To provide a sound signal generation device capable of artificially generating an engine sound signal indicating a realistic engine sound linked to running of an electric vehicle even when, for example, an engine is not mounted at all. A virtual engine rotation speed generation unit that acquires accelerator opening data indicating an accelerator operation amount in the electric vehicle and running speed data indicating a vehicle running speed of the electric vehicle, calculates a virtual running speed of a virtual engine vehicle, modifies the virtual running speed on the basis of the running speed data, and calculates an engine rotation speed of a virtual engine on the basis of the modified virtual running speed, and an artificial engine sound generation unit that generates a sound signal for outputting an artificial engine sound corresponding to a running state of the electric vehicle on the basis of the accelerator operation amount.
