    • A signal horn activation device for a motor vehicle comprises a pad (13) coupled to the steering wheel (11) to be pressed by the occupant for activating the signal horn (20), a pressure-sensitive means (15) coupled to said pad (13) to generate an electrical signal in response to pressure applied to said pad (13), and a signal processing means (18) arranged to activate the signal horn (20) in response to receiving said electrical signal from said pressure-sensitive means (15). The pressure-sensitive means (15) comprises at least one piezoelectric element (15) and said signal processing means (18) is arranged to evaluate changes of said electrical signal over time and to activate said signal horn (20) depending on the result of said evaluation.
    • 用于机动车辆的信号喇叭致动装置包括耦合到方向盘(11)以由乘员按压以激活信号喇叭(20)的衬垫(13),压敏元件 响应于施加在所述衬垫(13)上的压力而耦合到所述衬垫(13)以产生电信号的装置(15);以及响应于接收所述衬垫(13)而响应于所述信号处理装置(18) 来自所述压敏装置(15)的电信号。 压敏装置(15)包括至少一个压电元件(15),并且所述信号处理装置(18)被设置为评估所述电信号随时间的变化并且根据 说评价。
