US Patent 11286638 Loading machine control device and control method

An avoidance position specification unit specifies an interference avoidance position that is higher than a loading object and has no loading object therebelow. A timing determination unit determines a swing start timing based on a remaining swing angle formed by a straight line that extends from a center of swing to a work equipment and a straight line that extends from the center of swing to an interference avoidance position, and a height of the interference avoidance position. An operation signal output unit outputs an operation signal of the work equipment in a case of not reaching the swing start timing and outputs an operation signal for swinging a swing body at swing speed higher than that when not reaching the swing start timing and an operation signal of the work equipment, in a case of reaching the swing start timing.
