    • The invention concerns a device and method for detecting a squeezing by a motor-driven panel of an electric window or sliding roof of a vehicle. The panel is slidable between a first and a second position, while an opening of the vehicle is closed off in the first extreme position. The current through the motor is detected for detecting the possible squeezing of an object between the panel and the opening. A squeezing is detected when the magnitude of the current or a quantity derivable therefrom exceeds a predetermined threshold value. The motor is driven with a first speed when the panel is in a first path of movement between the first and second position and the motor is driven with a second speed when the panel is in a second path of movement between the first and second position. The panel within the first path of movement is located further away from a closed position than in the second path of movement. The second speed is chosen to be less than the first speed so that a squeezing of an object of a particular stiffness in the second path of movement results per unit time in a greater increase of the current than in the first path of movement, so that in the second path of movement a squeezing is detected with a greater accuracy.
    • 本发明涉及一种由电窗口的一个马达驱动的面板检测挤压或滑动的车辆的车顶的装置和方法。 该面板是第一和第二位置之间滑动,而在车辆的开口在第一极端位置被关闭。 用于检测所述面板和所述开口之间的对象的可能的挤压中检测通过所述马达的电流。 时,检测到挤压当电流的大小或量衍生有从超过预定的阈值。 马达被驱动以第一速度当面板是在运动的第一和第二位置之间的第一路径和所述马达被驱动以第二速度当面板是在运动的第一和第二位置之间的第二路径。 第一运动路径内的面板位于furtheraway从除了在运动的所述第二路径的关闭位置。 第二速度被选择为小于第一速度所以没有在每单位时间的移动导致的电流的比在第一运动路径更大的增加的第二路径的特定刚度的物体的挤压,所以没有 在运动的所述第二路径的挤压用更高的精度来检测。
