The invention discloses a control method for achieving steep slope slow descending and slope slipping prevention in a speed ring mode. The invention belongs to the technical field of electric tricyclecontrol. A controller judges the running state of an electric tricycle, if the electric tricycle is in the slope sliding state, the sector where the current vector is located is monitored in real time, and when the actual rotating speed of the motor is larger than the preset slope sliding preventing rotating speed, opposite driving force is provided for the sector where the is is located, so thatthe slope sliding rotating speed is stabilized at the preset slope sliding preventing rotating speed; and if the electric tricycle is in a steep slope quick-drop state, when the actual running speedof the motor is greater than the rotating speed value corresponding to the rotating handle, the vector sector where the is is located is determined, and opposite driving force is provided for the sector, so that the motor stably runs in a steep slope stage.
本发明公开一种使用速度环方式实现陡坡缓降和防溜坡的控制方法,属于电动三轮车控制技术领域,控制器判断车辆的运行态,如果电动三轮车处于溜坡状态,实时监测电流矢量i所在的扇区,当电机实际转速大于预设防溜坡转速时给i所在扇区一个相反的驱动力,使溜坡的转速稳定在预设防溜坡转速;如果电动三轮车处于陡坡速降状态,当电机实际运行速度大于转把对应的转速值时,判断i所在的矢量扇区,给i所在扇区相反的驱动力,使电机速度平稳的运行在陡坡阶段。
