JLR explained that initial tests will involve vehicle-to-vehicle and vehicle-to-infrastructure communications technologies that will allow cars to talk to each other and roadside signs, overhead gantries, and traffic lights. Ultimately, data sharing between vehicles would allow future connected cars to co-operate and work together to assist the driver and make lane changing and crossing junctions easier and safer.
JLR will induct over 100 vehicles for its autonomous technology research
Tony Harper, Head of Research, Jaguar Land Rover, said, "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."
Harper adds that the new technology will continue to operate in the background even if the driver is fully engaged in driving the car. And since the intelligent car will always be alert and is never distracted, it could guide you through road works and prevent accidents. He says, "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."
The research will comprise the following technologies:
Roadwork Assist: This technology uses a forward-facing stereo camera to generate a 3D view of the road ahead and together with advanced image processing software, it can recognise cones and barriers. Upon sensing roadwork, the system will identify an ideal path, inform the driver that the road is narrowing ahead, and apply a small amount of steering assistance to the wheel to help the driver remain centred in lane.
Safe Pullaway: It uses the stereo camera to monitor the area immediately in front of the vehicle. 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 brakes are automatically applied and the driver receives an audible warning.
Over the Horizon Warning: This is part of a research project testing devices that use radio signals to transmit relevant data from vehicle to vehicle. If vehicles were able to communicate independently, drivers and autonomous cars could be warned of hazards and obstacles over the horizon or around blind bends.
Emergency Vehicle Warning: It allows connected ambulances, police cars or fire engines to communicate with other vehicles on the road: a device in the emergency vehicle would broadcast that it is approaching before the driver could see or hear flashing lights and sirens. Drivers would receive an audible warning along with a visual alert telling them the direction the emergency vehicle is coming from and how far away it is: they can then safely pull over and allow the emergency vehicle to pass, which will minimise delays for the emergency services and prevent accidents.
