Document Type and Number:
WIPO Patent Application WO/2024/067488
Kind Code:
A1
Abstract:
A method and apparatus for determining a stable state of a rail transit vehicle. The method comprises: respectively determining a front straight line, a rear straight line, a left straight line and a right straight line in a reference coordinate system on the basis of reference coordinates of a left front sensor, a right front sensor, a left rear sensor and a right rear sensor in the reference coordinate system; respectively determining a front roll angle, a rear roll angle, a left roll angle and a right roll angle of a carriage on the basis of the slope of the front straight line, the slope of the rear straight line, the slope of the left straight line and the slope of the right straight line; and determining a stable state of the carriage on the basis of the front roll angle, the rear roll angle, the left roll angle and the right roll angle. Errors in determining a non-stable state of a vehicle can be reduced, such that subsequent analysis and evaluation are more accurate.
