Simulated sound generator for electric vehicles |
摘要 |
Based on detected information from a start sensor, a rotational speed sensor (or a vehicle speed sensor), and an accelerator opening sensor, a simulated sound selector device controls a simulated sound source device to generate a simulated sound signal corresponding to an operating condition of an electric vehicle when it starts, runs and is accelerated or decelerated, and also controls a sound level switcher device to adjust the level of the simulated sound signal. The simulated sound signal which is generated by the simulated sound source device and adjusted in level by the sound level switcher device is amplified by amplifiers, which drive respective loudspeakers to produce simulated sounds. The sound level switcher device is also controlled based on an ambient noise level detected by a noise sensor.
