The Society of Motor Manufacturers and Traders predicts the technology being developed for connected and autonomous vehicles will have prevented 25,000 accidents by 2030.
Warranty Direct looks at some of the key self-driving technologies making today’s vehicles safer and more efficient.
Most drivers will be familiar with ultrasonic sensors, with many vehicles already adopting the technology to help with reversing into tight parking spaces and more.
Ultrasonic sensors send out sound waves to detect surrounding objects. When the waves hit an object, it gives the car an accurate measurement of how close they are, to avoid collisions.
Blind-spot information system
Blind spot monitoring technology uses radar systems or rear-facing digital cameras, to sense vehicles which appear in a car’s blind spot. If this happens, a warning light shows in either the door mirror or within the A-pillar to alert the driver and make them aware of a potential hazard.
It’s become particularly useful when a motorist wishes to change lanes, as the technology offers an audible or haptic message if there is another vehicle in a car’s blind spot.
While it should reduce the number of collisions caused from changing lanes, drivers still need to check their blind spots and mirrors regularly and not become dependent on this technology alone.
Utilising IoT connectivity gives vehicles the ability to access wider data, like real-time traffic and weather updates, to ensure the safest and smoothest drive possible.
Connecting to a world of internet devices poses its problems, though. Privacy and safety are the biggest issue, with automated cars open to hacking, and the threat of information theft from connected devices like mobile phones.
Lane-keeping alert and automatic steering assist
By using a forward-looking camera, this technology has been developed to recognise when drivers are drifting out of a lane. Most vehicles will give either a visual or audible warning, but some higher-end motors now have automatic systems to divert a car safely back into the correct lane.
At the moment the technology is most effective on dry motorways and in a smooth flow of traffic, but there are developments being made to make it more precise and better suited to other situations such as driving on rural roads.
Traffic sign recognition
This uses a camera to scan road signs, then communicates this information back to either the dashboard or infotainment section of a vehicle.
All drivers should be well-versed on the Highway Code, which provides information on all the relevant road signs. However, this technology has been designed more as “extra driving assistance”, to help people when on unfamiliar roads or if they may have missed a change in the speed limit.
Automation is measured in five stages; with the final, most advanced stage being a fully autonomous system. This is when a vehicle’s performance is equal to that of a human driver.
The majority of vehicles are currently at stage two, which is what the systems listed earlier like park assist and lane-keeping alert are currently rated.
But what are some of the technologies the motoring industry has in the pipeline to take us to stage five?
Mercedes-Benz is currently working on a new technology – car-to-x – which will allow drivers to see ‘into the future’ – past multiple bends and maybe even further.
The sophisticated technology establishes networked links among and between vehicles and traffic infrastructure, so you can adjust your driving behaviour and defuse potentially dangerous situations.
The new GPS
Fully self-driving cars will rely on GPS devices to locate their position, helping to establish a route, know when to turn and more.
The worry is GPS devices can sometimes be off by a few metres, which would be extremely dangerous for a travelling vehicle. However, by connecting to other built-in sensors and cameras, vehicles can pinpoint an exact location.
