The invention discloses a driving mode switching control method for an oil-electricity dual-drive ship. The driving mode switching control method comprises the steps that a signal of a control system is obtained; the signals comprise a main engine clutch engagement/disengagement state signal, a main engine clutch engagement/disengagement execution signal, an axle motor rotating speed signal and a command rotating speed signal of a remote control system; judging a mode required by the axle motor according to the clutch on/off signal of the main engine; judging whether rotating speed control or torque control should be adopted currently according to the mode required by the axle motor; when the PTH mode needs to be switched to the PTI mode, the power management system controls the axle motor to be switched to the torque mode control in advance; when the PTI mode needs to be switched to the PTH mode, if the power management system collects that the state of a main engine clutch is switched from the on-off state, the shaft-driven motor is controlled to enter a rotating speed control mode; and when the axle motor is in the PTI mode, the power management system converts the axle motor into the PTO mode according to an external system command.
本发明公开了一种油电双驱动船舶的驱动模式切换控制方法,包括:获取控制系统的信号;信号包括主机离合器合/脱排状态信号、主机离合器合/脱排执行信号、轴带电机转速信号和遥控系统的命令转速信号;根据主机离合器合/脱排信号判断轴带电机所需模式;根据轴带电机所需模式判断当前应采用转速控制或转矩控制;当需要将PTH模式切换为PTI模式时,通过功率管理系统控制轴带电机提前转为转矩模式控制;当需要将PTI模式切换为PTH模式时,若功率管理系统采集到主机离合器状态从合排转为脱排,则控制轴带电机进入转速控制模式;当轴带电机处于PTI模式时,功率管理系统根据外部系统命令将轴带电机转为PTO模式。
