The invention belongs to the technical field of motor train unit traction control, and relates to a traction control method suitable for a motor train unit train, which comprises two traction characteristic curves for controlling a target speed in a train control system in a speed mode. The traction characteristic curve a suitable for the condition that normal wheel rail adhesion is good comprises a low-speed section and a constant-power section, and the traction characteristic curve b suitable for the condition that the wheel rail adhesion coefficient is low comprises a low-speed section, a constant traction force section and a constant-power section and is set according to the traction characteristic curve a; when the train runs, the wheel rail adhesion coefficient is preliminarily judged according to the current train running environment, and if the train running environment belongs to the situation that the wheel rail adhesion coefficient is low, the train is controlled according to the traction characteristic curve b; if the train operation environment is normal, the train is controlled according to the traction characteristic curve a; by means of the control method, time division of train operation can be guaranteed, and meanwhile the acceleration performance of the train can be fully exerted under the condition that the wheel rail adhesion is good.
本发明属于动车组牵引控制技术领域,涉及一种适用于动车组列车的牵引控制方法,该方法在速度模式下列车控制系统内有两种用于对目标速度进行控制的牵引特性曲线,适用于正常轮轨粘着较好情况的牵引特性曲线a包括低速区段和恒功率区段,适用于轮轨粘着系数较低情况的牵引特性曲线b包括低速区段、恒牵引力区段和恒功率区段,其是根据牵引特性曲线a进行设定的;列车运行时,根据当前列车运行环境初步判定轮轨粘着系数,若列车运行环境属于轮轨粘着系数较低的情况,则按照牵引特性曲线b控制列车;若列车运行环境正常,则按照牵引特性曲线a控制列车;此种控制方法既能确保列车运行时分,同时还能充分发挥轮轨粘着较好的情况下列车的加速性能。
