Embodiment Construction

[0033] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0034] At present, for the distribution of braking force in the train braking system, electric braking is used first, and air braking is applied only when electric braking is insufficient. When the air braking force is distributed, the strategy of equal adhesion or equal wear is generally adopted. No matter whether the air braking force is distributed by equal adhesion or equal wear,...

Abstract

The invention is suitable for the technical field of automatic control, and provides a vehicle braking force distribution method, terminal equipment and a storage medium. The method comprises the steps: calculating a target braking force according to a braking instruction, and obtaining an electric braking force which can be applied by a vehicle; when the target braking force is larger than the electric braking force, calculating the air braking force needing to be supplemented according to the target braking force and the electric braking force; distributing the air braking force to each brake disc with an available air braking function in the vehicle until each brake disc of the vehicle has the same air braking force or air braking power; calculating the current temperature of the brakediscs; and when the current temperature is smaller than the preset temperature threshold value, keeping the air braking force distributed to all the brake discs of the vehicle till braking is finished. The temperature of the brake discs is indirectly monitored by monitoring the air brake force or the air brake power of the brake discs, so that the temperature of the brake discs is prevented from being too high, and the brake reliability of the brake discs is enhanced.

Description

technical field [0001] The present application belongs to the technical field of automation control, and in particular relates to a vehicle braking force distribution method, a terminal device and a storage medium. Background technique [0002] At present, for the distribution of braking force in the train braking system, electric braking is used first, and air braking is applied only when electric braking is insufficient. The purpose of this is to feed the braking energy back to the power grid, and other trains can be used as power to meet the requirements of energy saving and environmental protection. temperature and increase the service life of the brake disc. Existing train braking systems generally adopt equal-adhesion or equal-wear strategies when distributing air braking force. Under the adhesion distribution scheme such as air brake, the train brake system will first distribute the air braking force to each trailer evenly according to the adhesion coefficient of th...
