Mobileye is a collision alert system that in some cases can be considered a lower classification of automated driving. The system itself does not actually control the car but instead, reads and monitors the roads and areas around the vehicle for potential threats.

The Mobileye system has many features that help keep the driver informed. Many of these same features are shared in self-driving cars – the future of driving.

The “Eye” in Mobileye

The most obvious feature is the dash cam, which continually scans the environment in front of the car. The system looks for bicycles, pedestrians, car speeds, sudden stops, lanes, and other features likely to occur during, and interfere with, driving. The system knows how fast you are going and it can calculate the relative speed of those around you. When it recognises a potentially dangerous situation, an alarm sounds almost three seconds before impact allowing the driver sufficient reaction time.

Changing Lanes

The Mobileye system is connected to the computer of the car, which it is installed in. If the car begins to change lanes without signalling, the system assumes that the driver is drifting into another lane unintentionally. When this happens, a warning alarm sounds giving the driver enough time to respond.

Additional to the alarm, the device itself has an indication as to which lane boundary has been crossed. This added visual cue allows the driver that extra information to make a quick decision in that short time.

Following Speed

Another great feature of the Mobileye system is the following distance meter. The device determines the speed of the car that it is installed in, the speed of the car in front of it, and figures out the theoretical stopping distance in time.

As you drive, the system will inform you when you have gotten within dangerous following distances, prompting you to slow down. The system also considers a lot when judging what a safe following distance is. If it is raining, for example, the distance automatically increases.


While the Mobileye system does not actually control the car, the ability to read the area around the car and inform the driver of any potential problems goes a long way in accident avoidance. Most accidents, after all, are the result of drivers not paying attention to the road. By using a system like this, drivers get fair warning before getting into any kind of collision.
