DRIVING-LINKED SOUND GENERATION DEVICE

摘要

A driving-linked sound generation unit includes an order sound data generation unit, a random sound data generation unit, and a synthesis unit. The order sound data generation unit generates order sound data by adjusting the pitch of the basic order sound data according to the revolving speed of the vehicle motor. The random sound data generation unit generates random sound data by adjusting the volume of basic random sound data, according to the revolving speed of the vehicle motor and an acceleration command value, without changing the pitch of the basic random sound data. The synthesis unit generates synthesized sound data by synthesizing the generated order sound data and random sound data.
