锁止块6与电机输出轴2上的限位挡块3处于脱离状态，不影响其旋转动作，电动踏板可以正常展开或收回。
锁止状态：
当电动踏板展开后，电机输出轴2上的限位挡块3处于图示位置，通过车内控制开关驱动伺服电机7工作，电机螺杆传动锁止块6向内运动，正好卡入限位挡块3处，限止了电机输出轴2的旋转，从而达到锁止功能。
如需解除，通过车内对应控制开关驱动伺服电机7反向运动。电机螺杆传动锁止块6向外运动，脱离限位挡块，恢复未锁止状态。

实施例2
带锁止功能的电动踏板的锁止机构的控制方法，包括以下步骤：
CAN控制系统向电动踏板控制器发送控制信号。所述电动踏板控制器收到控制信号，通过车内控制开关驱动伺服电机7工作，具体为：车内控制开关打开并延时3秒后，伺服电机7在汽车减速电机展开到位后正转，前端螺杆插入四连杆安装座1的限位销内。车内控制开关关闭，车内控制开关驱动伺服电机7反转，伺服电机7前端螺杆退出四连杆安装座1的限位销。若车门开关状态正 常，且车速≥15km/h或车门落锁信号，车内控制开关驱动伺服电机7反转。若车门开关状态正常，展开/回收力≦100N，则车内控制开关驱动电动踏板电机停止运转，电动踏板停止工作；或者，车内控制开关驱动伺服电机7正转或反转，使伺服电机7前端螺杆插入或退出四连杆安装座1的限位销，电动踏板展开或收回。
本发明通过电控及机械机构实现电动踏板机构自锁的方法，能够实现通过按钮触发手工实现机构的自锁及解锁。
注意，上述仅为本发明的较佳实施例及所运用技术原理。本领域技术人员会理解，本发明不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整和替代而不会脱离本发明的保护范围。因此，虽然通过以上实施例对本发明进行了较为详细的说明，但是本发明不仅仅限于以上实施例，在不脱离本发明构思的情况下，还可以包括更多其他等效实施例，而本发明的范围由所附的权利要求范围决定。
