13.7.2016Jaguar Land Rover working on advanced safety systems
Jaguar Land Rover is set to start testing connected and autonomous vehicle (CAV) technologies, with a fleet of more than 100 cars planned to be involved over the next four years.
The group will begin trials later this year on a new 41 mile test route set up on a mixture of urban roads and motorways around Coventry and Solihull, announced in February 2016. This living laboratory will see vehicles test systems on along the test corridor such as vehicle-to-vehicle and vehicle-to-grid communication.
Systems confirmed as being developed currently include Roadwork Assist, Safe Pullaway, Over the Horizon Warning, and Emergency Vehicle Warning. These are a combination of autonomous and connected systems that aim to make driving safer and less stressful. JLR's head of research Tony Harper says: "Our connected and automated technology could help improve traffic flow, cut congestion and reduce the potential for accidents.
"We will also improve the driving experience, with drivers able to choose how much support and assistance they need. In traffic, for example, the driver could choose autonomy assist during tedious or stressful parts of the journey.
"But even when an enthusiastic driver is fully focussed on enjoying the thrill of the open road, the new technology we are creating will still be working in the background to help keep them safe. Because the intelligent car will always be alert and is never distracted, it could guide you through road works and prevent accidents. If you are a keen driver, imagine being able to receive a warning that there's a hazard out of sight or around a blind bend. Whether it's a badly parked car or an ambulance heading your way, you could slow down, pass the hazard without fuss and continue on your journey."
Roadwork Assist uses a forward-facing stereo camera to generate a 3D view of the road ahead and can recognise road furniture such as cones and barriers. The system will sense when the vehicle is approaching the start of the roadworks, identify an ideal path through complicated construction sites and contraflows, and inform the driver that the road is narrowing ahead. It will then apply a small amount of steering assistance to the wheel to help the driver remain centred in lane.
Safe Pullaway aims to prevent low speed collisions by using the same camera as used in Roadwork Assist. Driving in traffic jams or pulling out of junctions are common causes of accidents, while sometimes drivers crash into walls by putting the car into the wrong gear - heading forward when they intended to go backwards out of a garage for example.
Safe Pullaway monitors the area immediately in front of the vehicle and, if objects such as vehicles or walls are detected and the system receives signals from throttle pedal activation or from gear selection that could lead to a collision, the vehicle's brakes are automatically applied and the driver receives an audible warning.
Over the Horizon Warning is a project that is testing using radio signals for vehicle-to-vehicle communication. This would allow cars further down the road to warn drivers of upcoming hazards out of sight. If a vehicle has slowed or stopped, and poses a risk to other motorists, it would send a "Hazard Ahead" warning to nearby vehicles. Approaching vehicles will then receive a visual and audible warning, informing the driver of the hazard.
The system would not only make journeys safer but also has the potential to reduce the number of traffic jams, improving both road capacity and vehicle emissions in the area.
Emergency Vehicle Warning allows connected ambulances, police cars or fire engines to communicate with other vehicles on the road by sending out a message to them. This will warn the driver that an emergency vehicle is approaching, enabling the driver to get out of the way safely and quickly. The system will be able to inform the driver from which direction the emergency vehicle is coming and how far away it is.
