Abstract
An operation assistance system for a work machine includes an operation assistance function and a work assistance function. Both of the operation assistance function and the work assistance function are switchable between enabled and disabled states. When the work assistance function is in an enabled state and when the work area is set outside of the stop area to surround the stop area, the operation assistance system sets the work area as the stop area such that the stop area is extended and overlaid on the work area, and automatically enables the operation assistance function when the operation assistance function is in a disabled state.
