Abstract
An automatic train control device which has a detector for detecting whether a newly received train speed signal instruction is for instructing the train to run at a lower speed than that according to an earlier signal while the train is running at a speed within the range according to the instruction received by an earlier signal, and thus finds itself running at a speed exceeding the speed according to the newly received instruction. A differential speed detector, which is connected to the signal detector, detects the excess of the train speed over the speed according to the newly received instruction. A memory outputs one braking instruction from among a plurality of stored optimum braking patterns to a device which controls the application of the brake according to the output from the memory, the memory output being in response to an excess train speed.
