Vehicle backward sliding protection method and related device

Abstract

The invention discloses a vehicle backward sliding protection method. The method comprises the steps that the average value of the speeds of multiple motors is calculated; whether the vehicle slides backwards or not according to the mean value is judged; if the vehicle slides backwards, the backward sliding stage of the vehicle is determined according to the mean value; and according to the backward sliding stage of the vehicle, a protection measure corresponding to the backward sliding stage is executed. By applying the method, the vehicle can be prevented from shaking, and the availability of the vehicle can be guaranteed while the safety of the vehicle is considered. The invention further discloses a vehicle backward sliding protection apparatus and device and a computer readable storage medium which all have the technical effects.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a method for preventing a vehicle from slipping behind; it also relates to a device, equipment and a computer-readable storage medium for preventing a vehicle from slipping behind. Background technique [0002] In the field of rail transit, when the train starts on a ramp, if the traction force is small, the vehicle may slip backwards. The main reason is that the upward traction force of the vehicle is less than the downward force of the vehicle's gravity component, such as figure 1 As shown, M in the figure represents the weight of the vehicle, g represents the acceleration of gravity, and β represents the slope angle. The reason for the small traction force is generally that the traction level given by the driver or the signal system is too small, or the vehicle has a single or multi-section power abnormality. [0003] Vehicle slipping backwards is an unsafe sta...

Problems solved by technology

[0004] For the vehicle slipping backwards, the current technical solution is to apply emergency braking when the vehicle is recognized as slipping backwards, which will not only bring a large impact, cause discomfort to passengers, but also prolong the departure time of the vehicle, and even cause the vehicle to be delayed

Or take a negative feedback control method based on the speed of a single motor. However, in actual applications, there are multiple different motors working at the same time. This control method is likely to cause the traction force and braking force between multiple motors to be out of sync, and the vehicle shakes.
