Automobile body pitching angle detection system, control system and corresponding automobile

The invention provides a detection system and a control system for an automobile body pitching angle and an automobile with the detection system or the control system. The detection system comprises a front torsion bar mechanism, a rear torsion bar mechanism, a hydraulic coupling system, a displacement measurement device and a pitching angle calculation unit. When the automobile inclines longitudinally, the translation motion of a front suspension and a rear suspension of the automobile in the vertical direction relative to an automobile body is converted into movement of a piston in the hydraulic coupling system, so that the pitching angle of the automobile body can be calculated according to the displacement of the piston. The detection system provided by the invention is simple in structure, convenient to mount, high in precision and low in cost and can accurately measure the pitching angle of the automobile body of the automobile in real time. The control system provided by the invention ...
