Abstract
A working machine has a body and a load handling apparatus coupled to the body. The load handling apparatus is moveable with respect to the body by an electrically driven actuator assembly. A controller is configured to receive a tilt signal representative of a moment of tilt of the working machine and issue a control signal configured to control an electrical drive element of the electrically driven actuator assembly based on the value of the tilt signal relative to a tilt threshold.
Claims20
A working machine comprising:
- a body and a load handling apparatus coupled to the body, wherein the load handling apparatus is moveable with respect to the body by an electrically driven actuator assembly, the electrically driven actuator assembly including a hydraulic actuator, a hydraulic pump configured to provide hydraulic fluid to the hydraulic actuator, and an electrical load handling motor operatively coupled to the hydraulic pump to drive the hydraulic pump;
- a control system, the control system operatively coupled to the electrical load handling motor, and wherein the control system comprises a controller configured to:
- receive a tilt signal representative of a moment of tilt of the working machine, and
- issue a control signal configured to control at least one of the hydraulic pump or the electrical load handling motor to control a supply of hydraulic fluid to the hydraulic actuator based on the value of the tilt signal relative to a tilt threshold;
- wherein the control signal is configured to reduce the speed of at least one of the hydraulic pump and/or the electrical load handling motor as the value of the tilt signal approaches the tilt threshold.
