Lane Departure vs. Lane Keeping vs. Lane Centering Tech
Advanced driver assistance systems (ADAS) are innovative technology features that use sensors, cameras, radar, and lidar to keep you safe on the road by reducing the impact force of an accident or avoiding a collision altogether. But with so many different ADAS systems available these days, it can be confusing for consumers to differentiate between them.

A good example of this confusion is the safety tech that helps prevent drivers from drifting around on the road. There are three primary types of systems in this category: lane-departure warning (LDW), lane-keeping assistance (LKA), and lane-centering assistance (LCA).
Though the overall goal of each system is the same, they operate differently to keep vehicles within the driver’s intended lane of travel. But the distinctions between them can become blurry, especially when each automaker has its own naming convention for each system (i.e., Honda’s nomenclature for lane keeping assistance is “Road Departure Mitigation” while its lane-centering technology is called “Lane Keeping Assist”).
The best way to understand how each of these systems works is to first define them in a standardized way without the proprietary names assigned by manufacturers.
