Autonomous all-terrain capability for Land Rover
JAGUAR Land Rover has demonstrated autonomous driving technologies that works both on and off road.
Head of research at Jaguar Land Rover Tony Harper said the group’s all-terrain autonomy research isn’t just about the car driving itself on a motorway or in extreme off-road situations, but about safely traversing any terrain or driving situation.
“We don’t want to limit future highly automated and fully autonomous technologies to tarmac.
“When the driver turns off the road, we want this support and assistance to continue. In the future, if you enjoy the benefits of autonomous lane keeping on a motorway at the start of your journey, we want to ensure you can use this all the way to your destination, even if this is via a rough track or gravel road.”
To enable this level of autonomous all-terrain capability, Jaguar Land Rover’s researchers are developing next-generation sensing technologies that will be the eyes of the future autonomous car.
Because the sensors are always active and can see better than the driver, this advanced sensing will ultimately give a vehicle the high levels of artificial intelligence required for the car to think for itself and plan the route it should take, on any surface.
3D path sensing
The systems in the cars combine camera, ultrasonic, radar and light and radar (Lidar) sensors to give the car a 360-degree view of the world around it, with sensors so advanced that the car could determine surface characteristics, down to the width of a tyre, even in rain and falling snow, to plan its route.
Ultrasonic sensors can identify surface conditions by scanning up to five metres ahead of the car, so Terrain Response settings could be automatically changed before the car drives from tarmac to snow, or from grass to sand. This will optimise allterrain performance, without loss of momentum or control.
Cameras check for potholes
Terrain-based speed adaption (TBSA) uses cameras to sense bumpy terrain, including uneven and undulating surfaces and washboard roads, potholes and even standing water. It is then intelligent enough to predict the potential impact of these surfaces on the car’s ride and automatically adjust speed to keep passengers comfortable.
Sharing map updates
In a world-first off-road demonstration, Jaguar Land Rover has connected two Range Rover Sports together using innovative DSRC (Dedicated Short Range Communications) technology to create an Off-Road Connected Convoy. This wireless vehicle-to-vehicle communications system shares information including vehicle location, wheel-slip, changes to suspension height and wheel articulation, as well as All-Terrain Progress Control (ATPC) and Terrain Response settings instantly between the two vehicles. — Supplied.
Many self-driving car systems are being tested on road, Jaguar Land Rover is the first to take theirs off-road.
