Abstract: A control method for hybrid electromagnetic suspension. The method provides four modes for hybrid electromagnetic suspension: a comfort mode, a sport mode, a combined mode, and an energy feedback mode. A driver can switch between the four modes as desired. For the comfort, sport, and combined modes, hybrid control is adopted, and two sub-modes are provided: an active control mode and a semi-active control mode. A switching condition between the two sub-modes is determined by using a novel parameter Cact and comparing the same against a maximum equivalent electromagnetic damping coefficient Ceqmax of a linear motor. The present invention solves the problem of achieving a balance between suspension comfort and tire traction, and meets the demands of different operating conditions and users by enabling manual mode switching. In addition, the hybrid control is employed to solve the problems of high energy consumption of active suspension and limited control performance of semi-active suspension, thus ensuring good kinematic performance of automobile suspension while reducing energy consumption. Furthermore, the energy feedback mode is designed to enable the suspension to perform energy recovery, meeting demands of energy conservation and emission reduction.

Abstract: A cooperative control module, an adaptive cruise system and a control method thereof, and a vehicle are provided. The adaptive cruise system comprises a vehicle sensor module, a driving environment intelligent sensing module, a vehicle state response estimation module, an adaptive cruise and controllable suspension cooperative control module, and a power control module. The control method of adaptive cruise is optional, one is according to the cruise speed set by the driver, and the other one is according to the cruise comfort set by the driver. In the case of adaptive cruising according to cruise comfort, the optimal cruise speed is intelligently calculated by the adaptive cruise and controllable suspension system based on driving conditions and driver's demands. The controllable suspension is controlled cooperatively during cruising, and the suspension control parameters are adaptively switched according to the performance requirements of the vehicle under different driving conditions.
