The present invention relates to a method of estimating a vehicle roll angle for an active suspension control system. The method includes: a step in which a roll angle estimation model receives at least one among a lateral acceleration measurement value, an active roll system (ARS) roll moment, and an electronic control suspension (ECS) damping force from a vehicle including a lateral acceleration sensor measuring lateral acceleration, an ARS reducing a roll angle, and an ECS controlling a damping force of a suspension; and a step in which the roll angle estimation model estimates a vehicle roll angle by using at least one among the lateral acceleration measurement value, the ARS roll moment and the ECS damping force, inputted from the vehicle. Therefore, the present invention is capable of accurately estimating a roll angle of a vehicle by using control information.
