The invention provides an automatic control method and device of an excavator and a wheel excavator. The excavator comprises an energy accumulator, a brake valve and a switch electromagnetic valve. The energy accumulator is respectively connected with the brake valve and the switch electromagnetic valve; the method comprises the steps of obtaining instant rotating speed parameters of an engine of the excavator; and determining that the excavator is in a stopped state according to the instant rotating speed parameter, and sending a starting signal of a first strategy which is used for adjusting the liquid filling amount of the energy accumulator to the brake valve through the switch electromagnetic valve to prevent the excavator from sliding and breaking. Whether the machine is stopped or not is judged through an engine rotating speed sensor, when the rotating speed sensor is zero, the machine is in a stopped state, and when the rotating speed sensor is larger than zero, the machine is in a running state; a starting signal of a first strategy is sent during parking, the controller controls an accelerator voltage signal, a certain accelerator signal is compensated, the traction force of the machine is increased, and the problem that the machine slides at the starting moment is avoided.
本发明提供一种挖掘机的自动控制方法、自动控制装置及轮式挖掘机，挖掘机包括：蓄能器、刹车阀和开关电磁阀；蓄能器分别与刹车阀和开关电磁阀连接；方法包括：获取挖掘机的发动机的即时转速参数；据即时转速参数确定挖掘机处于停车状态，发出第一策略的启动信号，第一策略用于通过开关电磁阀调节蓄能器向刹车阀的充液量，防止挖掘机溜破。本发明通过发动机转速传感器，判断机器是否停车，当转速传感器为零时，机器处于停车状态，转速传感器大于零时，机器处于行驶状态；停车时发出第一策略的启动信号，控制器控制油门电压信号，补偿一定的油门信号，增加机器的牵引力，避免机器起步瞬间出现溜破问题。
