Title
(EN) Device for active control of sound insulation in autonomous vehicle passenger compartment
(ZH) 在自动驾驶车辆的驾驶舱中主动控制隔音的设备
Abstract
(EN)
A control device (DC) is fitted to a vehicle (VA) which can be driven by a driver during a manual driving phase and which comprises a passenger compartment (H) fitted with a loudspeaker (HP) capable of diffusing sound signals and an assistance device (DA) for driving the vehicle in a totally autonomous manner during an autonomous driving phase. The device (DC) comprises acquisition means (MA) forrecording first sound signals present in the external environment of the vehicle (VA), and control means (MC) for generating, during an autonomous driving phase, second sound signals in phase opposition to the first recorded sound signals, in order to supply same to the loudspeaker (HP) so that the transmission of the signals induces cancellation of the first sound signals in the passenger compartment (H).

(ZH)
一种可配备至车辆(VA)的控制设备(DC),该车辆在手动驾驶阶段可由驾驶员驾驶并包括驾驶舱(H)和辅助设备(DA),该驾驶舱配备有能够传播声音信号的扬声器(HP),该辅助设备在自动驾驶阶段能够以完全自动的方式驾驶车辆。该设备(DC)包括采集装置(MA)和控制装置(MC),该采集装置可记录存在于车辆(VA)外部环境中的第一声音信号,该控制装置可在自动驾驶阶段期间产生与已记录的第一声音信号相位相反的第二声音信号,以便向扬声器(HP)提供第二声音信号,从而使得第二声音信号的传播促使在驾驶舱(H)中消除第一声音信号。
