Embodiments of the present invention provide a rail vehicle braking control method and system, and a rail vehicle. The rail vehicle braking control method includes: obtaining the current braking force demand value of the rail vehicle; based on the obtained current braking force demand value, controlling the internal combustion power pack to operate in the auxiliary power generation device braking mode, diesel engine friction braking mode or hydraulic transmission Select among box braking modes to drive the rail vehicle for braking. The rail vehicle braking control method and system provided by the embodiments of the present invention, as well as the rail vehicle, are used to solve the defect that the rail vehicle braking force range is small in the prior art, and realize that the braking force of the internal combustion power pack is provided by the traditional transmission fluid Power braking is changed to anti-drag auxiliary power generation device, diesel engine friction and gearbox hydraulic braking to jointly provide the effect of mixed braking force.
Description
technical field [0001] The invention relates to the field of rail vehicles, in particular to a rail vehicle brake control method and system, and a rail vehicle. Background technique [0002] In the current field of rail vehicles, the main feature of the hydraulic transmission power pack is that it can help the vehicle provide braking force, and it can reduce the wear of the brake pads when used on a long slope. The braking force of the traditional hydraulic transmission power pack is mainly provided by the hydraulic gearbox, and the braking force range is small. In order to make full use of power pack braking and reduce the use of vehicle brake pads, it is necessary to increase the braking force range of the power pack as much as possible. And this has become one of the problems to be solved urgently in the rail vehicle field at present. Contents of the invention [0003] Embodiments of the present invention provide a rail vehicle braking control method and system, as we...
