Abstract: Mappings of keys to actions can automate various vehicle systems. Some automations can provide lane departure warnings or emergency light reminders. Mapping keys can be matched based on vehicle condition data gathered from vehicle sensors. When a mapping key matches vehicle condition data, the vehicle action automation system can cause the vehicle to perform the one or more actions from that mapping. Mapping keys can be rules-based and/or model-based. Keys for lane departure mappings can specify vibration patterns expected when a vehicle drives over lane delineators. These vibration-based mappings can include keys with vibration patterns, e.g., defining vibration frequencies or vibration locations. Keys for emergency light mappings can be based on conditions such as (1) the vehicle being on the road, stopped, not in traffic, and not at a stop signal; (2) components of the vehicle having failed; or (3) weather conditions.
