The invention discloses a braking control method and system for a standing forward moving type forklift truck. The method comprises the steps that a monitoring signal of the forklift truck is obtained; based on the accelerator signal and the parking signal, the driving state of the forklift is determined; under the condition that the driving state is braking, if the portal bearing signal, the portal forward moving signal, the portal backward moving signal and the running speed signal meet the corresponding triggering conditions, the driving motor is controlled to start regenerative braking, and the first brake and the second brake are controlled to conduct braking according to the specified proportion; and controlling the first brake and the second brake to cancel braking until the vehicle speed indicated by the driving speed signal is reduced to the speed value indicated by the accelerator signal. According to the method, under the braking scene, the driving motor is triggered to start regenerative braking, the first brake and the second brake conduct braking according to the specified proportion, the braking performance of the driving wheel, the left front wheel and the right front wheel is improved, and the phenomenon that any one of the driving wheel, the left front wheel and the right front wheel is locked is avoided.

    本申请公开了一种站驾前移式叉车的制动控制方法及系统,该方法为:获得叉车的监控信号;基于加速器信号和驻车信号,确定叉车的驾驶状态;在驾驶状态为刹车制动的情况下,如果门架承重信号、门架前移信号、门架后移信号、行驶速度信号满足对应的触发条件,控制驱动电机启用再生制动,以及控制第一制动器和第二制动器分别按照指定比例进行制动,直至行驶速度信号所示的车速减速至加速器信号所示的速度值,控制第一制动器和第二制动器取消制动。该方法通过在刹车制动场景下,触发驱动电机启用再生制动,第一制动器和第二制动器分别按照指定比例进行制动,提高驱动轮、左前轮和右前轮的刹车性能,避免驱动轮、左前轮和右前轮中任一者发生抱死现象。
