All current automobile suspensions are reactive, which means when when a vehicle's wheel rolls over a bump or dip in the pavement, the change in wheel position causes the suspension to compress or extend in response. Bose's Active Suspension technology basically has a computer that tells a powerful actuator at each wheel exactly when, which way, how far, and how fast to move.

According to Car and Driver, "the computer making these decisions uses a network of sensors to measure, for example, the car's speed, longitudinal and lateral accelerations, and forces and accelerations acting at each wheel. The computer then commands the wheel to move in the ideal way for the existing circumstances. No more compromise between ride and handling, rough roads and smooth roads, high speeds and low speeds."
