How do Self Driving Cars Work?

Monday November 26, 2018

Autonomous cars are big news globally, due to the safer rider they will offer us in the future. According to statistics, >90% of road accidents are caused by human error, which it is the ambition of autonomous vehicles to eliminate. This will mean less demand for emergency services, fewer insurance premiums, and savings in accident-related health care for everyone (IoT For All).

Autonomous cars have a number of systems that work together to guide the vehicle along the road and keep passengers, pedestrians, and other road users safe. Radar sensors on the car monitor the position of the car and other road users, while video cameras detect traffic lights, road signs, and look out for other vehicles, pedestrians, and other obstacles. Lidar sensors help to detect the edges of roads and identify lane markings by bouncing pulses of light off the car’s surroundings. There are also ultrasonic sensors on the wheels to detect kerbs and parked cars. All this data is analysed by a central computer (The Telegraph).

There is one key component for self-driving cars still needs to be developed: 5G cellular networks. 5G networks allow for wireless transfer of data much more rapidly than the 4G LTE connections that we currently have, with 5G being close to 1,000% faster than 4G LTE, which will help to solve high latency and make long waiting times a thing of the past. 5G networks will allow for seamless communication between autonomous cars, and allow for further integration of of IoT devices (Landmark Dividend).

High purity quartz and silica will be instrumental to the rollout of 5G networks across North America, Asia, Europe, and elsewhere. The fibre optic market is forecast to growth at a CAGR of 7.2% to 2026, and the Quartz Corp is a supplier of high purity quartz sand to the fibre optic value chain (Business Wire).
