Embodiment Construction
[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0033] During the braking process of the rail vehicle, according to the existing electric brake parking principle, the electric brake of the rail vehicle is required to be braked to zero first, and then the holding brake is applied. If the rail vehicle stops on a slope, the braking force (including the braking force of the electric brake or the br...

Embodiments of the present invention provide a rail vehicle brake control method, device, electronic equipment, and storage medium, including: according to the air brake response time of the rail vehicle, the signal transmission delay time of the rail vehicle, and the maximum braking allowed by the rail vehicle The impact rate, the minimum speed point for the electric brake to completely exit and the slope of the running line determine the minimum speed point for applying the holding brake; when the rail vehicle reaches the minimum speed point for applying the holding brake or reaches the minimum speed point for applying the holding brake A holding brake control command is applied before the vehicle speed point. The rail vehicle braking control method, device, electronic equipment, and storage medium provided by the embodiments of the present invention calculate the minimum vehicle speed point for applying the holding brake by integrating various factors, which not only avoids the vehicle slipping caused by the wrong timing of applying the holding brake , and the calculation process is simple, does not need to consume a lot of resources, and has no site requirements.
Description
technical field [0001] The invention relates to the technical field of rail vehicle control, in particular to a rail vehicle braking control method, device, electronic equipment and storage medium. Background technique [0002] Rail vehicle braking refers to artificially stopping the motion of a rail vehicle, including slowing it down, not accelerating it, or stopping it. [0003] EB0 mode is a mode of rail vehicle braking, and its meaning refers to electric braking to zero. In principle, the electric braking stop requires that the holding brake be applied when the electric braking of the vehicle reaches zero. However, when the rail vehicle is on a slope, if the holding brake is applied when the electric brake of the vehicle reaches zero, the problem of rolling is likely to occur during the parking process. In addition, this method also has the problem that the EB0 electric braking capacity is not fully utilized and the braking characteristics of the vehicle are inconsiste...
