Abstract
A work machine may include a steering system, a user interface, a detection device, and a control device. The user interface may generate an input signal corresponding to operator input. The detection device may generate a detection signal corresponding to a presence of an operator relative to the user interface. The control device may determine that the operator is unavailable based on the detection signal and the input signal, and enable a lockout mode based on determining that the operator is unavailable. The control device may determine, while the lockout mode is enabled, a readiness indicator. The readiness indicator may confirm a readiness of the operator based on determining that the detection signal satisfies a readiness criterion. The control device may disable the lockout mode based on determining that the readiness criterion is satisfied.
