Abstract
A suspension control apparatus includes: a variable damper; a communication unit provided inside a vehicle to receive a dynamic map from a cloud; and a controller configured to adjust a force generated by the variable damper. The controller includes: a state estimation unit, which is provided inside the vehicle, and is configured to detect a motion of the vehicle; an operation-stability controller configured to calculate an Acommand value for the variable damper based on internal information output from the state estimation unit; and a dynamic-map controller configured to calculate an FF command value for the variable damper based on the dynamic map received from the communication unit. The controller determines a command value for the variable damper from the Acommand value and the FF command value.
