Active-passive dual mode switchable vehicle suspension system and switching method therefor

An active-passive dual mode switchable vehicle suspension system. The system comprises a filter (1), a hydraulic pump (2), a check valve (3), a power takeoff (4), a servo valve (6), a suspension cylinder (7), a overflow valve (9), an energy accumulator (10), a reversing valve (11), a first pressure sensor (12), a second pressure sensor (13), a controller (14), a fuel tank (15) and a displacement sensor (16). Further related is a switching method for the active-passive dual mode switchable vehicle suspension system. When switching the mode, the fuel hydraulic pressure in the rodless cavity of the suspension cylinder is adjusted in advance to be equal to the fuel hydraulic pressure in the energy accumulator, a stable switching between active and passive suspension modes is thus achieved so as to eliminate oscillation of the vehicle body during the existing switching between active and passive suspension systems. Moreover, the energy accumulator and the overflow valve can be shared in active and passive suspension modes, thereby effectively decreasing the usage amount of energy accumulators and overflow valves, greatly saving the space of the vehicle body, effectively reducing the gross mass of the vehicle body and facilitating the light weight of the vehicle chassis.

Active-passive dual mode switchable vehicle suspension system and switching method therefor

An active-passive dual mode switchable vehicle suspension system is provided. The suspension system includes a filter, a hydraulic pump, a one-way valve, a power takeoff, a servo valve, a suspension cylinder, an overflow valve, an energy accumulator, a reversing valve, a first pressure sensor, a second pressure sensor, a controller, an oil tank and a displacement sensor. Further related is a switching method for the active-passive dual mode switchable vehicle suspension system. When the active and passive dual-mode switchable vehicle suspension system is switched between modes, an oil pressure in the rodless cavity of the suspension cylinder and an oil pressure in the energy accumulator are adjusted to be equal in advance, so that the stable switching of the active-passive suspension system can be realized, and the vibration of the vehicle body is eliminated when the existing active-passive suspension system is switched. Moreover, the accumulator and overflow valve can be shared in the active and passive suspension mode, thereby effectively reducing the use number of accumulators and overflow valves, greatly saving the layout space of the vehicle body, effectively reducing the total weight of the vehicle body, which is favorable to the lightweight of the vehicle chassis.

Active suspension inertia regulation method based on vehicle-front terrain, and control system

Disclosed in the present invention are an inertial regulation method of active suspensions based on terrain ahead of a vehicle (1) and a control system thereof. According to the scanned terrain ahead of the vehicle (1), a center of mass trajectory and attitude history are calculated when the vehicle passes through the terrain ahead of the vehicle (1) 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.
