Title:
ACTIVE SUSPENSION CONTROL DEVICE, SYSTEM, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/109642
Kind Code:
A1
Abstract:
An active suspension control device, system, and method. The device comprises: a microcontroller (2), an ultrasonic sensor (1), a vehicle wheel longitudinal acceleration sensor (3), and a vehicle body longitudinal acceleration sensor (4). The vehicle wheel longitudinal acceleration sensor (3) acquires a vehicle wheel longitudinal acceleration signal, and transmits the same to the microcontroller (2). The vehicle body longitudinal acceleration sensor (4) acquires a vehicle body longitudinal acceleration signal, and transmits the same to the microcontroller (2). The ultrasonic sensor (1) emits ultrasonic waves according to a set angle, and transmits a received echo signal to the microcontroller (2). The microcontroller (2) calculates, according to the echo signal, a reference current I of a damper (6), and calculates, according to the vehicle wheel longitudinal acceleration signal and the vehicle body longitudinal acceleration signal, a target current I' of the damper (6), and adjusts, according to the reference current I and the target current I', an input current of the damper (6).
