The problem to be solved by the present invention is to provide an electric suspension device capable of simplifying or omitting a system structure and improving the measurement accuracy of the position of an electric actuator. In order to solve the problem, the electric suspension device is mounted on a vehicle and comprises: an electric actuator that performs a stroke operation in accordance with the behavior of the vehicle; a motor that drives the electric actuator; a rotation angle sensor that detects a rotation angle of the motor; and a control device that controls the electric actuator. The control device calculates the stroke amount of the electric actuator on the basis of the amount of change in the rotational angle of the rotational angle sensor, and controls the electric actuator on the basis of the calculated stroke amount.
本发明所要解决的问题在于,提供一种电动悬架装置,能够简化或省略系统构造,并提升电动致动器的位置的测定精度。为了解决上述问题,电动悬架装置搭载在车辆上,且包括:电动致动器,根据车辆的行为进行行程动作;马达,驱动电动致动器;旋转角传感器,检测马达的旋转角;及,控制装置,控制电动致动器;并且,控制装置基于旋转角传感器的旋转角变化量算出电动致动器的行程量,且基于算出的行程量控制电动致动器。
