Advanced driver-assistance systems (ADAS) are a clever collection of systems that help drivers stay safe. ADAS have been developed to automate many of a car’s safety systems, with the aim of reducing the chances of human error, which account for over 90% of all collisions on the road.

A lane departure warning (LDW) system is a form of electronic driver assistance that warns the driver when their car begins to stray outside of its lane, unless the indicator has been switched on to show that a lane switch is intentional. 

The car uses cameras and sensors to see the lane markings and, if they tell the system that the car is not between the lines, an alert (a beeping sound, light or vibrating steering wheel) is triggered to warn the driver.

The point of the system is to minimise accidents caused by driver error, distraction and drowsiness, keeping you in check.

A pedestrian detection system is one of the current generation of driver assistance systems that use radar and cameras to spot potential collisions. In this case, the technology can identify the more subtle movements of pedestrians, but is more effective at slower speeds. 

Pedestrian detection can’t always avoid a collision – especially if a car is driving at 30mph or faster – but the ability of the system to automatically apply the brakes can help reduce the speed enough to lessen the impact.

LiDAR stands for ‘light detection and ranging’. 

It is a type of sensor that works in a similar way to radar, but instead of using radio waves it sends out pulses of infrared light millions of times a second, and measures how long they take to come back after bouncing off objects close to it. This allows it to build a form of constantly changing 3-D map of what is around it.

LiDAR is becoming more commonplace on modern cars, as they adopt driver assistance systems that will be the basis of autonomous driving.
