The invention discloses a traction force control method, device and equipment and a medium, and relates to the field of rail transit. The method comprises the following steps: acquiring a traction target value and a running speed of the heavy-load locomotive, and acquiring a traction characteristic curve of the heavy-load locomotive; acquiring a current speed interval of the heavy-load locomotive according to the running speed and the traction characteristic curve; wherein the current speed interval comprises a constant force area, a moment limiting area and a constant power area; and according to the traction target value and the current speed interval, the traction of each axle of the heavy-load locomotive is adjusted to compensate the axle load. According to the scheme, the current speed interval of the heavy-load locomotive is determined according to the running speed of the heavy-load locomotive and the traction characteristic curve, so that the traction force of each shaft of the heavy-load locomotive is adjusted according to different intervals; the scheme creatively starts from whole vehicle control, and traction compensation of all shafts of the locomotive is carried out in advance; the defect that the target traction force is averagely distributed to all the shafts in the prior art is overcome, and the traction performance and the adhesion utilization rate of all the shafts of the heavy-load locomotive are effectively improved.

    本申请公开了一种牵引力控制方法、装置、设备及介质,涉及轨道交通领域。通过获取重载机车的牵引力目标值和运行速度,并获取重载机车的牵引特性曲线;根据运行速度和牵引特性曲线获取重载机车的当前速度区间;其中,当前速度区间包括恒力区、力矩限制区和恒功区;根据牵引力目标值和当前速度区间分别调节重载机车各轴牵引力,以进行轴重补偿。上述方案根据重载机车的运行速度与牵引特性曲线确定重载机车所在的当前速度区间,从而根据不同区间分别调节重载机车各轴牵引力;方案创造性的从整车控制出发,提前进行机车各轴的牵引力补偿;弥补了以往项目将目标牵引力平均分配到各个轴的缺陷,有效的提升了重载机车各轴的牵引性能及黏着利用率。
