  • Publication number: 20230286347
    Abstract: Disclosed in the present invention are an inertial regulation method of active suspensions based on terrain ahead of a vehicle and a control system thereof. According to the scanned terrain ahead of the vehicle, a center of mass trajectory and attitude history are calculated when the vehicle passes through the terrain ahead of the vehicle with passive suspensions. After smoothing the trajectory, the active suspension is controlled to make the vehicle drives according to the smoothed trajectory. During this period, a smoothness coefficient is adjusted to make each suspension stroke be limited within a limit stroke, and according to the supporting force and stroke of each active suspension calculated from a dynamics model, the impedance control based on force-displacement is carried out on an actuator of the suspension. The present invention can significantly improve the driving comfort and handling stability of the vehicle driving on an uneven road surface.

  • Publication number: 20230286345
    Abstract: An inertial regulation method and control system of vehicle active suspension based on a supporting force of each wheel comprises an inner loop control and an outer loop control. The inner loop control is to calculate, according to the dynamics, a theoretical supporting force of each wheel when the vehicle is driving on a virtual slope plane with a 6-dimensional acceleration and a pitch angle measured by an inertial measurement unit; compare the theoretical supporting force with the measured supporting force of each wheel; and control the expansion of each suspension cylinder according to the difference value, so that the supporting force of each wheel changes according to the theoretical supporting force. The outer loop control is to control each suspension cylinder for the same expansion of displacement, so that the average value of all the suspension cylinder strokes tends to a median value.
