Problems solved by technology

The inventors found that in the manual driving mode, because the speed selection value of the handle may exceed the ATP speed limit value or the maximum allowable speed value of the vehicle, it is difficult to ensure the stable operation of the vehicle at a constant speed; on the other hand, because the vehicle is difficult to run at a stable speed, When the station interval is long, the driver needs to keep fine-tuning the main control handle, which increases the difficulty for the driver to operate the vehicle

Abstract

The invention belongs to the field of vehicle control, and provides a control method and system for constant-speed operation of a rail transit vehicle and the vehicle. The control method for constant-speed operation of the rail transit vehicle comprises the steps that an ATP speed limit value, a handle speed selection value and a vehicle maximum allowable speed value are obtained and compared, andthe minimum value of the three values is determined as the vehicle target speed; and the operation state of a traction inverter is controlled according to the comparison result of the target speed ofthe vehicle and the current speed of the vehicle so as to ensure that the vehicle operates at the target speed at a constant speed. The constant-speed operation speed can be automatically adjusted according to the ATP speed limit, and the safety of a vehicle is guaranteed.

Description

technical field [0001] The invention belongs to the field of vehicle control, and in particular relates to a control method, a control system and a vehicle for rail transit vehicles running at a constant speed. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The automatic driving mode is to output the traction or braking status and level information through the ATC system, and the vehicle applies the corresponding traction or braking force to realize the acceleration or deceleration of the vehicle. The inventors found that in the manual driving mode, because the speed selection value of the handle may exceed the ATP speed limit value or the maximum allowable speed value of the vehicle, it is difficult to ensure the stable operation of the vehicle at a constant speed; on the other hand, because the vehicle is difficult to run at a stable sp...
