To improve safety, automotive original equipment manufacturers (OEMs) are increasingly adding advanced driver assistance systems (ADAS) to their automotive products. Unfortunately, instead of making cars safer, some of these ADAS systems inadvertently expose passengers to higher levels of danger. For example, some drivers take their hands off the steering wheel when using automatic cruise control, which does not meet the requirements for lane keeping assist system (LKAS). While some drivers may simply want to test the system's limits, others may have a misunderstanding of the system's mimicry capabilities and mistakenly believe that "hands-off" operation is permitted under certain circumstances. If this behavior is not addressed, it can have disastrous consequences. Therefore, UN R79 adds the following new provisions for LKAS: requiring cars to monitor driver behavior and sound an alarm if the driver removes his hands from the steering wheel after LKAS is enabled. This feature is often called Hands Off Detection (HoD). .
