Problems solved by technology

[0005] However, the existing magneto-rheological suspension system control methods either only consider the vibration control of the vehicle body, such as the ceiling damping control method, or do not consider the vibration control of the vehicle body in the process of controlling the vehicle body attitude, that is: The algorithm of body attitude control (such as during sharp turns) does not consider the signal of vibration control (such as ceiling damping control)
This has led to poor overall performance of the suspension control system, which does not take into account the ride comfort and handling stability of the vehicle.

Embodiment Construction

[0025] see figure 1 As shown, a vehicle magneto-rheological suspension system control device with summing mode provided by an embodiment of the present invention includes a sensor, a signal processing unit, a suspension system controller, a damping force control module, a magneto-rheological damper and a suspension frame spring. The sensors include a variety of body sensors: relative displacement of the shock absorber, body acceleration, vehicle corner, body inclination, accelerator opening, vehicle speed, brake pressure sensor, etc., which are used to obtain the motion status of the body and shock absorber online in real time. These sensors are connected to the signal processing unit through a direct connection, or a vehicle bus, such as a CAN bus. The signal processing unit can also receive manual input instructions from the driver, such as the setting of the driving mode: "sports mode", "cruise mode" and so on. The signal processing unit can process the received raw sensi...

Abstract

The invention discloses a control device and a control method of a summing-mode vehicle magnetorheological suspension system. The control device comprises a signal processing unit, a suspension system controller, a damping force control module and a plurality of magnetorheological dampers. The control device and the control method have the advantages that a vehicle body posture control algorithm and a vehicle body vibration control algorithm are operated in real time, results of the two control algorithms are taken into consideration comprehensively, and accordingly, better comprehensive performance is achieved; vehicle handling stability is focused, and vehicle driving is safe.

Description

technical field [0001] The invention relates to a vehicle suspension system, more specifically, it relates to a control device and method for a vehicle magneto-rheological suspension system with a summing mode. Background technique [0002] Suspension system is an important subsystem of the car, which is closely related to the handling of the car, and it plays an important role in isolating the vehicle vibration caused by the uneven road excitation. The semi-active suspension system of a car is generally composed of a spring and a controllable damping shock absorber. The controllable damping shock absorber can adjust the damping coefficient in real time according to the vehicle operating conditions to achieve the optimal match with the elastic components to improve the vehicle performance. Ride comfort and handling stability. [0003] Magneto-rheological shock absorbers have attracted widespread attention in vehicle suspension systems and have been successfully applied. Th...
