The invention relates to the technical field of rail transit, in particular to a method and system for calculating the effective braking distance and braking energy height of a vehicle, and the method comprises the steps: collecting the opening size of a speed reducer in real time through a hump control system, and recording the moment when the opening size of the speed reducer reaches a specified state and a radar speed value; calculating the running distance of the train set when the speed reducer brakes the train set; constructing a train set wheel set coordinate sequence, and constructing a coordinate relation of the ith train set wheel set at a full braking moment and a non-full braking moment based on the running distance of the train set when the speed reducer brakes the train set; according to the coordinate relation of the ith vehicle set wheel set at the full braking moment and the non-full braking moment, the effective braking distance of the speed reducer to the ith vehicle set wheel set is calculated; and according to the effective braking distance of the speed reducer to the ith vehicle group wheel pair, the effective braking distance of the speed reducer to the vehicle group is calculated. The method can effectively calculate the effective braking distance and braking energy of the train set, and can also be applied to train sets with different numbers and weight grades.
