The invention discloses a traction control method and system which is used for rail transportation equipment. The rail transportation equipment is internally provided with a switching switch used forswitching traction modes. The method comprises the steps that a traction mode trigged by the switching switch is received; when the traction mode is a torque mode, torque level information of a motorman controller is identified, the target torque of a train is set according to the torque level information, and traction force or electric braking force is applied by cooperating with a traction system to achieve the target torque of the train; and when the traction mode is a speed mode, speed level information of the motorman controller is identified, the target speed of the train is set, and traction force or electric braking force is applied by cooperating with the traction system to achieve the target speed of the train. According to the traction control method, the traction system can becontrolled correspondingly according to the traction mode trigged by the switching switch, fusion switching of the double traction modes is achieved, a driver can switch the switching switch manuallyand freely by combining with the current operation demand, adaptability to the specific operation demand of a line can be improved, and operation is safe and convenient.
Description
technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a traction control method for rail transit equipment. In addition, the invention also relates to a traction control system for rail transit equipment. Background technique [0002] In rail transit equipment, there are mainly two traction modes: torque mode and speed mode. At present, the traction mode of each rail transit equipment is single, and some mainly adopt the torque control mode, that is, a traction mode in which the on-board network control system cooperates with the traction system to control the train to achieve the target torque; others mainly adopt the speed control mode, That is, a traction mode in which the on-board network control system cooperates with the traction system to control the train to reach the target speed. [0003] However, for EMU trains in rail transit equipment, only a single traction mode can not meet its precise speed control and ...
