Optical Technologies Are the Key For Automated Driving

Automated Driving is one of the major topics for our mobility of the next decades. Simple Levels of automated driving (e.g. Automatic Cruise Control or Lane Keeping) are available today, the next level where the driver is allowed to do other tasks is to be introduced by 2020.

The final stage of automated driving is full automation, which means that there is no task for the driver anymore. This is the most critical level, as the vehicle will have to monitor all safety-critical driving functions on its own. Each function will need redundancy for fully automated driving. Different technologies should be used, to reduce the failure case to as close to zero as possible. So for example for the 360° surround view and positioning, cars will have to use in parallel Radar, LIDAR, cameras and GPS.

These developments in automated driving are one reason why LIDAR adoption is predicted to drastically increase in the next decade. As well as this, the steering angle sensor needs to have two redundant measurements, for example in magnetic and optical technology. In the higher levels of automated driving, the takeover time of the driver after a phase with other activities is crucial. Therefore good driver observation is necessary inside the car, which can for example be done with a 3D TOF camera sensor. Finally, but one of the most important points, automated cars will be connected with each other and the surrounding infrastructure. Besides broadband and WIFI data transfer, optical infrared communication can be used for data transmission, to build smart streets and smart cities to optimize traffic routing in the future.
