A device, system and method for controlling an active suspension are provided. The device includes: a Micro Control Unit (MCU), an ultrasonic sensor, a vehicle wheel longitudinal acceleration sensor, and a vehicle body longitudinal acceleration sensor. The vehicle wheel longitudinal acceleration sensor acquires a vehicle wheel longitudinal acceleration signal and transmits it to the MCU. The vehicle body longitudinal acceleration sensor acquires a vehicle body longitudinal acceleration signal and transmits it to the MCU. The ultrasonic sensor excites an ultrasonic wave according to a set angle, and transmits a received echo signal to the MCU. The MCU calculates a reference current I of a shock absorber according to the echo signal, calculates a target current I′ of the shock absorber according to the vehicle wheel longitudinal acceleration signal and the vehicle body longitudinal acceleration signal, and regulates an input current of the shock absorber according to the reference current I and the target current I′.
