Kind Code:
A1
Abstract:
Provided are a device and method for controlling an electronically controlled suspension with which deterioration in damping performance can be minimized even if the accuracy of estimating an unsprung state of rear wheels decreases. A variable damper is provided to a vehicle having front wheels and rear wheels. A controller is provided with a trajectory correspondence detection unit that detects the correspondence between the trajectories of the front wheels and the rear wheels when the vehicle is traveling, and a command value calculation unit that calculates a control amount command value, which is a control amount of the variable damper of the rear wheels, in accordance with the correspondence relationship of the trajectories.
