Considered science fiction just a couple of decades ago, self-driving vehicles are an emerging reality, made possible by the development of high-performance smart sensors. Technological progress in the digital and microcontroller spheres has made it possible to create sensors for lane keeping, adaptive cruise control, blind-spot detection, and other advanced driver assistance systems. ADAS features such as parking assist are both helpful tools for drivers and important solutions for meeting higher automotive safety standards. For example, the Euro NCAP Protocol, which regulates car safety standards in Europe and defines evaluation models, has mandated a set of ADAS safety features for inclusion in new vehicles.

LiDAR: What it is, how it works

Light detection and ranging (LiDAR), which uses electromagnetic radiation in the optical band for remote detection and measurement, is among the critical sensor technologies enabling ADAS. LiDAR is used today for pedestrian detection, blind spot detection, adaptive cruise control, and other applications that require detection and mapping of all the elements surrounding the vehicle.
