#4What’s the difference between automated driving and ADAS?

The difference between automated driving and ADAS can be boiled down to the level of human intervention. Up to what level are drivers responsible, and from what level can cars help us? It is this threshold that separates between automated driving and ADAS.

The target of ADAS is, needless to say, to increase the scene where collisions are avoidable as much as possible. For example, surveys and classification on actual collisions have been conducted at a lot of developed countries. Those surveys analyze the details of accidents occurred, such as the types of accidents and the numbers of respective cases, how fast the cars were driving, what percentage of accidents were fatal, and so on. We can quantify what percentage of accidents can be prevented if an ADAS function is introduced to vehicles on the road. By continuing that effort, we can achieve the goal of ‘Zero Collisions’. In short, evolution of ADAS can be regarded as the process to eliminate the situations where collisions could occur by introducing various technologies.

Of course, not only functional improvement but also prevalence of technology is a key factor. It is an everlasting issue for ADAS. Once, it took a very long time to raise the seat belt use rate in the past. It might be the same for drivers to change their awareness toward safe driving.

From that perspective, we can expect a lot from popularization of automated driving. As the merits of automated driving are clear for users, it can prevail more easily than ADAS. Vehicles with the automated driving technology naturally have a high-level of ADAS capability. If a vehicle has sensors and control devices that can perform automated driving, it means that a high level of ADAS functions is working while a human driver is in control. Technology for automated driving actually helps the popularization of ADAS.If automated driving becomes popular, ADAS prevails at the same time. It will reduce collisions without fail.
