    • The invention relates to a method for determining the ground clearance of an automobile, including a step that comprises deriving (260) the ground clearance of the automobile from the output voltage (Vout) of a sensor (28). The invention comprises: using, as a sensor (28), an electric generator comprising an electromechanical transducer comprising at least one layer of an electro-active polymer material (10) arranged between at least one pair (100, 110) of electrodes (12, 12', 14, 14'), wherein said layer (10) and the electrodes are integrated into a bellow (2) made of a flexible material that surrounds a link between two non-aligned shafts (4, 6) and is rotatingly driven with the latter, the layer (10) of electro-active polymer material and the electrodes (12, 12', 14, 14') extending longitudinally relative to the shafts; recording (200) the peak value of the output voltage (Veap) of each pair of electrodes (100, 110) after scaling (Vsc); selecting (210) a pair of electrodes from said pairs; and setting (220) the output voltage (Vout) of the sensor (28) on the basis of the output voltage (Vsc) of the selected pair of electrodes.
    • 本发明涉及一种用于确定汽车的离地间隙的方法,包括步骤:从传感器(28)的输出电压(Vout)导出(260)汽车的离地间隙。 本发明包括:使用作为传感器(28)的发电机,其包括机电换能器,其包括至少一层布置在至少一对电极(100,110)之间的电活性聚合物材料(10) ,12',14,14'),其中所述层(10)和电极被集成到由柔性材料制成的波纹管(2)中,所述波纹管(2)围绕两个未对准的轴(4,6)之间的连接并且旋转 由电驱动聚合物材料的层(10)和电极(12,12',14,14')相对于轴纵向延伸; 在缩放(Vsc)之后记录(200)每对电极(100,110)的输出电压(Veap)的峰值; 从所述对选择(210)一对电极; 并根据所选择的一对电极的输出电压(Vsc)设定(220)传感器(28)的输出电压(Vout)。
