The invention relates to the technical field of parking control, in particular to a deceleration control method and system, a deceleration interval is set, and a distance inflection point and a pre-stop speed are set in the deceleration interval; the deceleration interval is divided into a first deceleration interval and a second deceleration interval by the distance inflection point; through the maximum speed value of the second deceleration interval, the speed running state of the first deceleration interval is limited; the mobile platform linearly decelerates in the second deceleration interval to reach a pre-stop speed and runs at the pre-stop speed to reach a target position after the rest distance, parameter adjustment factors P1 and P2 are introduced, a function relation between the real-time speed of the driving motor and the real-time position of the mobile platform is constructed, and the real-time position of the mobile platform is determined. The parameter adjusting factors P1 and P2 can adjust the length of the speed reduction interval, the corresponding completion time and the slope of linear speed reduction, a user can set the speed reduction state in a user-defined mode, the influence of a control algorithm of the frequency converter is not limited any more, expandability is higher, and any frequency converter of the same specification can be replaced and is not influenced by the factors such as the speed and the distance.

    本发明涉及停车控制技术领域,具体涉及减速控制方法及系统,设定减速区间,在减速区间内设置路程拐点和预停速度;路程拐点将减速区间分为第一减速区间和第二减速区间;通过第二减速区间的最大速度值,限定第一减速区间速度运行状态;移动平台在第二减速区间内线性减速达到预停速度,并以预停速度运行完剩余路程到达目标位置,引入调参因子P1和P2,构建驱动电机的实时速度和移动平台的实时位置之间的函数关系,调参因子P1和P2能够调节减速区间的长度和对应的完成时间,以及线性减速的斜率,用户能够自定义设置减速状态,不再受限于变频器自带的控制算法的影响,可扩展性更高,任何同规格的变频器均可以替换,不受速度,距离等因素影响。
