The invention provides a technology capable of providing an operation feeling and riding comfort suitable for a driver of an automobile. An ECU (1) controls a suspension device of a vehicle by estimating an operation induction state quantity caused by an operation of the vehicle by using an operation induction state quantity estimation unit (100), and estimating a road surface induction state quantity caused by a road surface by using a road surface induction state quantity estimation unit (200). An operation induction state quantity is converted into a damping force required for operation induction by an operation induction state quantity conversion unit (300), a road surface induction state quantity is converted into a damping force required for road surface induction by a road surface induction state quantity conversion unit (400), and a current value to be applied to a suspension device is determined from the above value by a current value calculation unit (500).
本发明提供了一种能够提供适于汽车驾驶员的操作感觉和乘坐舒适性的技术。ECU(1)通过如下方式控制车辆的悬架装置:通过利用操作诱导状态量估计部(100)估计由车辆的操作引起的操作诱导状态量,通过利用路面诱导状态量估计部(200)估计由路面引起的路面诱导状态量,通过利用操作诱导状态量转换部(300)将操作诱导状态量转换成操作诱导所需阻尼力,通过利用路面诱导状态量转换部(400)将路面诱导状态量转换成路面诱导所需阻尼力,并且通过利用电流值计算部(500)根据上述值确定施加到悬架装置的电流值。
