JAGUAR LAND ROVER ANNOUNCES TECHNOLOGY RESEARCH PROJECT TO DETECT, PREDICT AND SHARE DATA ON POTHOLES

• Jaguar Land Rover’s pioneering ‘Pothole Alert’ research could help save motorists billions of pounds in punctures, vehicle damage and road accidents every year
• Range Rover Evoque research vehicle can identify the location and severity of potholes and broken manhole covers – and adjust suspension in milliseconds
• Jaguar Land Rover researchers developing technology to share this data with other cars via the cloud so all drivers get a warning about dangerous potholes
• Research with Coventry City Council to understand how sharing data with road authorities could enhance the speed and efficiency of road repairs

Whitley, UK: Jaguar Land Rover is researching a new connected car technology that will allow a vehicle to identify the location and severity of potholes, broken drains and manhole covers, and then share this data in real-time via the cloud with other vehicles and with road authorities to help them prioritise repairs.

If a car can receive a warning from another vehicle about severe potholes or broken manholes ahead, then drivers would be able to slow down and avoid the danger – or the car could adjust suspension settings to reduce the impact and smooth the ride. This could help reduce the potential for punctures, wheel and vehicle damage as well as road accidents.

Dr Mike Bell, Global Connected Car Director, Jaguar Land Rover, said: “Our MagneRide equipped Range Rover Evoque and Discovery Sport vehicles feature sophisticated sensors that allow the vehicle to profile the road surface under the wheels and identify potholes, raised manholes and broken drain covers. By monitoring the motion of the vehicle and changes in the height of the suspension, the car is able to continuously adjust the vehicle’s suspension characteristics, giving passengers a more comfortable ride over uneven and damaged road surfaces.
PREDICTING POTHOLES ON THE ROAD TO AUTONOMOUS DRIVING

The next stage of the project at Jaguar Land Rover’s Advanced Research Centre in the UK is to install new road surface sensing technology in the Range Rover Evoque research vehicle, including an advanced forward-facing stereo digital camera.

“At the moment the most accurate data comes from when the car has driven over the pothole or manhole”, added Mike Bell. “So we are also researching how we could improve the measurement and accuracy of pothole detection by scanning the road ahead, so the car could predict how severe they are before the vehicle gets near them.

“Ultimately, sensing the road ahead and assessing hazards is a key building block on our journey to the autonomous car. In the future, we are looking to develop systems that could automatically guide a car around potholes without the car leaving its lane and causing a danger to other drivers. If the pothole hazard was significant enough, safety systems could slow or even stop the car to minimize the impact. This could all help make future autonomous driving a safe and enjoyable reality.”
• The cost of vehicle damage caused by potholes in the UK is estimated at £2.8bn every year
• MagneRide is a high-performance, semi-active suspension control system that responds in real time to road and driving conditions based on input from sensors that monitor body and wheel motion.
• Thanks to a special damping fluid containing magnetic particles the system can respond instantly. When the particles are subjected to a magnetic field, the viscosity of the damper fluid is either increased or decreased, making the suspension stiffer or softer.
