The invention discloses an acceleration and deceleration control method for a driving motor of an electric window wiper of a rail transit vehicle, which relates to the technical field of driving motor control and comprises the following steps: when the window wiper works normally, judging the position information of a wiping arm of the window wiper through a position sensor; when the wiper arm of the window wiper reaches the stop position of the point A, the control system of the window wiper controls the driving motor to start accelerating, and when the wiper arm of the window wiper reaches the point B, the driving motor accelerates to a normal speed and stops accelerating; keeping normal speed at the point C, starting to decelerate at the point D, decelerating to the lowest speed and starting to accelerate at the extreme position of the point E, and accelerating to the normal speed and stopping accelerating at the point F; the normal speed is kept at the G point, the speed is reduced at the H point, and the speed is reduced to the lowest speed and accelerated at the limit position of the A point; the cycle is repeated to form acceleration and deceleration control of the driving motor; when the wiper arm of the window wiper runs to two endpoint positions, the wiping frequency is reduced, the acceleration during reversing is reduced, and the overall stability and reliability of the window wiper are further improved.
本发明公开了一种轨道交通车辆电动刮雨器驱动电机加减速控制方法,涉及驱动电机控制技术领域,包括:在刮雨器正常工作下,通过位置传感器判断刮雨器刮臂的位置信息;当刮雨器刮臂到达A点停止位置,则刮雨器控制系统控制驱动电机开始加速,当到达B点时,加速到正常速度并停止加速;在C点持续正常速度,到D点开始减速,到E点极限位置时减速到最低速度并开始加速,到F点加速到正常速度并停止加速;到G点持续正常速度,到H点开始减速,到A点极限位置时减速到最低速度并开始加速;如此循环,构成驱动电机的加减速控制;使得刮雨器刮臂在运行到两端点位置时降低刮刷频率,降低换向时的加速度,进而提高刮雨器整体的稳定性和可靠性。
