Abstract

The invention discloses a magneto-rheological damping suspension and a measurement and control method thereof, and relates to the technical field of electric vehicles. The magneto-rheological dampingsuspension comprises a frame for connection, wherein hub motor tires are arranged on two sides of the frame and connected with the frame through magneto-rheological damping shock absorbers. The magneto-rheological damping shock absorbers are arranged, damping provided by the magneto-rheological damping shock absorbers is adjusted in real time through an electronic control unit, the damping changerequirements under various vehicle driving conditions can be met, a vehicle is prevented from bearing strong vibration impact in the driving process, and the comfort of passengers is improved; the magneto-rheological damping shock absorbers are connected with a stator bracket, large transverse force can be borne while vertical vibration of a vehicle body is reduced, and the structure is more compact. The hub motors are adopted to drive the vehicle, electric energy required for controlling the magneto-rheological damping shock absorbers and electric energy for driving the hub motors can be provided by the same vehicle-mounted power supply, an energy supply structure does not need to be additionally arranged, the weight of the vehicle body is reduced, and then energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a magneto-rheological damping suspension for electric vehicles and a measurement and control method thereof. Background technique [0002] New energy vehicles are one of the important directions for the development of the automobile market. Hub motor drive technology is the top priority in the development of new energy vehicles represented by electric vehicles. At the same time, hub motor drive technology has been used more and more in actual production. ground application. However, in actual use at present, the in-wheel motor generally cooperates with the traditional automobile suspension unit to drive the vehicle. The traditional automobile suspension unit cannot fully match the actual situation of the in-wheel motor, resulting in the overall structure of the vehicle is not compact enough; in addition, the closely connected with the in-wheel motor The suspension syst...
