Lisäohjaus

Lisäohjaus (Finnish: "additional control" or "auxiliary guidance") is a general term for any supplementary control or guidance mechanism that augments a primary control system. The concept appears in multiple domains, including engineering, transportation, industrial automation and education, where an extra control channel, assistive input or advisory function supports the main control loop or operator.

In technical systems, lisäohjaus can mean an auxiliary actuator, remote override, fine-tuning input or software module that improves precision, provides redundancy, or enables special operating modes. Examples range from auxiliary steering systems in vehicles and aircraft to backup controllers in process plants and user-assistive interfaces in consumer electronics. Implementations typically combine hardware and software elements and may work in closed-loop or supervisory configurations.

In human-centered contexts, the term also describes added guidance for users or learners — for instance, targeted instructional support, adaptive prompts or assistive technology that supplements primary teaching or operational procedures. Such lisäohjaus aims to improve usability, safety and performance without replacing the principal method.

Benefits of lisäohjaus include increased reliability, enhanced control precision and greater adaptability. Challenges include system integration complexity, potential for conflicting commands, increased cost and the need for rigorous safety validation and clear human–machine interaction design. Regulatory, ergonomic and cybersecurity considerations can influence design and deployment.
