Abstract
An active control system for vehicle suspensions includes a detection module which detects a vehicle running state and a front road condition by means of an advanced mode or a standard mode; a calculation module which comprehensively calculates, in combination with running data and dimensions of a vehicle and the front road condition data collected by the detection module and according to passenger comfort requirements, target data of adjustment; and an implementation module which adjusts a height of each suspension of the vehicle according to the target data obtained by the calculation module.
Claims6
An active control system for vehicle suspensions, comprising a detection module, a calculation module and an implementation module,
- wherein the detection module detects a front road condition by means of an advanced mode or detects a vehicle running state by means of a standard mode;
- in combination with running data and dimensions of a vehicle and the front road condition data collected by the detection module and according to passenger comfort requirements, the calculation module comprehensively calculates a target height to which inner and outer suspensions need to be adjusted when a vehicle turns, or target heights to which front and back suspensions need to be adjusted when the vehicle accelerates or decelerates, or a target height of each suspension when the vehicle accelerates or decelerates on a bend;
- and
- according to target data obtained by the calculation module, the implementation module adjusts a height of each suspension of the vehicle by means of a hydraulic suspension system, an air suspension system, or an electromagnetic suspension system, such that a vehicle chassis has an inner side lower than an outer side to properly and actively incline inwards when the vehicle turns, the vehicle chassis has a front side lower than a rear side to properly and actively incline forwards when the vehicle rapidly accelerates, and the vehicle chassis has a front side higher than a rear side to properly and actively incline backwards when the vehicle rapidly decelerates.
