The invention discloses a method for controlling an oil pump motor of a pure electric mining dump truck, which comprises the following steps of: when the truck is in a starting state, setting a motor control mode as a rotating speed control mode; when the parking brake switch is released, the gear of the gear shifter is a forward gear or a reverse gear, the target rotating speed of the oil pump motor is controlled to be the rotating speed required by a hydraulic system for ensuring safe driving of the vehicle; and when the vehicle is parked and braked, the gear of the gear shifter is a neutral gear, and the gear of the lifting handle is a lifting gear or a descending gear, the target rotating speed of the oil pump motor is controlled to linearly change along with the opening degree of the accelerator pedal. The vehicle operation state is identified by analyzing the vehicle key information, and the oil pump motor is flexibly and efficiently controlled to drive the hydraulic oil pump to operate according to the vehicle state.
本发明公开了一种纯电动矿用自卸车油泵电机控制方法,包括:车辆处于启动状态,设置电机控制模式为转速控制模式;当驻车制动开关松开、换档器档位是前进档或者换档器档位是倒档,控制油泵电机目标转速为确保车辆安全行驶的液压系统需求转速;当车辆已实施驻车制动并且换档器档位为空档,举升手柄档位是举升档或下降档,控制油泵电机目标转速随油门踏板开度线性变化。本发明通过分析车辆关键信息来识别车辆运行状态,根据车辆状态灵活、高效地控制油泵电机驱动液压油泵运转。
