Embodiment Construction

[0020] figure 1 It is a flowchart of a method for controlling a vehicle slipping provided by an embodiment of the present invention. Such as figure 1 As shown, the method of controlling the rolling of the vehicle includes:

[0021] Step 11, the traction converter obtains the running direction information of the vehicle from the speed sensor, and obtains the direction command information sent by the controller.

[0022] Wherein, the vehicles can be rail vehicles such as light rail, subway and railway vehicles.

[0023] Acquiring the running direction information of the vehicle may specifically obtain the running direction of the vehicle through a speed sensor, such as forward, backward or stopped.

[0024] Obtain the direction instruction information issued by the controller, such as obtaining the forward, backward or stop instruction issued by the controller, it can be known that the driver's operation is running forward, running backward or stopping.

[0025] Step 12, the...

Abstract

The invention provides a method for controlling vehicle sliding, and a traction converter, as well as a rail car. The method includes: the traction converter acquires the running direction information of a vehicle from a speed sensor, and acquires directional instruction information from a driver controller; the traction converter compares the obtained running direction information with the directional instruction information to judge whether the vehicle slides; and if the vehicle slides, the traction converter adopts corresponding measures to make the vehicle stop sliding. By adopting corresponding measures to prevent sliding after knowing that the vehicle slides, the vehicle safety is ensured, and the safety of vehicle operating is improved.

Description

technical field [0001] The invention relates to vehicle control technology, in particular to a method for controlling vehicle rollback, a traction converter and a rail car. Background technique [0002] Rail cars such as light rail, subway and railway vehicles often need to be parked at sites with a certain slope. Therefore, the rail car is equipped with an anti-rolling system to take necessary effective braking measures at the slope site to prevent the rail car from rolling. At the same time, prevent the vehicle from rolling due to insufficient power when the vehicle starts on these slopes, especially prevent the rail car from sliding backward, so as to avoid the risk of life and property safety of passengers in the rail car caused by the derailment of the rail car. [0003] At present, the anti-rolling system of a rail car mainly includes a traction rheometer, and a mechanical braking method is used to prevent the rail car from rolling at a station with a slope. Specifica...
