Description

technical field [0001] The invention relates to an adaptive calculation method for a full-speed close-fitting operation control curve of a rail transit train, in particular to an adaptive calculation method for a full-speed close-fitting operation control curve of a train used in a rail transit train operation control system. Background technique [0002] The full-speed train operation control curve of the rail transit train operation control system is the train operation curve with the highest operating efficiency. The basis of design, etc., is one of the key factors affecting the comprehensive service level of rail transit operations. [0003] The full-speed tight running control curve of rail transit trains is composed of train traction running curve, cruising running curve and braking running curve. According to the reference curve of train running at full speed (no train traction operation reference curve) obtained in advance budget, referring to the actual conditions ...
