The invention discloses a sound simulation method, a corresponding sound simulation system and a motor vehicle with the sound simulation system. The method comprises the following steps: S1, collecting vibration signals of an engine and/or a vehicle body; s2, processing the collected vibration signal to obtain at least one digital signal containing sound information; s3, generating a driving signal for driving at least one vehicle-mounted loudspeaker based on the digital signal; and S4, sending the driving signal to at least one vehicle-mounted loudspeaker so as to drive the at least one vehicle-mounted loudspeaker to generate expected sound in the compartment. Through the method and the system, engine roar can be simulated in a targeted manner according to selection, so that the driving experience of a driver is improved; and/or according to the noise condition of the motor vehicle in the current running state, giving out a sound which counteracts or at least partially attenuates the noise in a targeted manner so as to realize the active noise reduction of the compartment.
本发明公开了一种声音模拟方法、一种相应的声音模拟系统及具有该声音模拟系统的机动车,该方法包括以下步骤:S1:采集发动机和/或车身的振动信号;S2:对所采集的振动信号进行处理以获得至少一个包含声音信息的数字信号;S3:基于所述数字信号产生用于驱动至少一个车载扬声器的驱动信号;S4:将所述驱动信号发送到至少一个车载扬声器以驱动该至少一个车载扬声器在车厢内部产生期望的声音。通过该方法和系统能根据选择针对性地模拟发动机轰鸣,以提升驾驶员的驾驶体验;和/或根据机动车当前运行状态下的噪声情况针对性发出抵消或至少部分衰减噪音的声音,以实现对车厢的主动降噪。
