Problems solved by technology

[0002] During the braking process, the vehicle is usually disturbed by the uncertain parameters of the slope condition of the line, and it is difficult to reduce its influence by traditional control methods
For example, the conventional braking control method usually uses the ideal braking force on a straight road as the control feedback amount, but this often fails to obtain the ideal braking effect

Abstract

The invention provides a method and a system for controlling self-adaption gradient braking of a railway vehicle. The method comprises the following steps: estimating the ramp information at the next moment according to a current driving condition of the vehicle; calculating a target braking force according to the estimated ramp information; taking the target braking force as a control feedback volume and controlling the pressure of a braking cylinder. According to the method for controlling self-adaption gradient braking of the railway vehicle provided by theinvention, the braking force of the vehicle can be real-time adjusted according to the condition of line gradient, so that the adaptation of the vehicle to uncertain parameters under the ramp condition in the practical braking process can be increased.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of vehicle control, in particular to a method and system for adaptive slope control of rail vehicles. Background technique [0002] During the braking process, the vehicle is usually disturbed by the uncertain parameters of the slope condition of the line, and it is difficult to reduce its influence by traditional control methods. For example, the conventional braking control method usually uses the ideal braking force on a straight road as the control feedback amount, but this often fails to obtain the ideal braking effect. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a rail vehicle adaptive slope control method and system. The rail vehicle adaptive slope control method provided by the present invention can adjust the braking force of the vehicle in real time according to the slope of the line, thereby improving the ve...
