Jaguar Land Rover is developing autonomous cars capable of all-terrain, off-road driving in any weather condition. The world-first CORTEX project will take self-driving cars off-road, ensuring they are fully capable in any weather condition: dirt, rain, ice, snow or fog. As part of the project, a ‘5D’ technique combining acoustic, video, radar, light detection and distance sensing (LiDAR) data live in real-time is being engineered. Access to this combined data improves the awareness of the environment the car is in. Machine-learning enables the self-driving car to behave in an increasingly sophisticated way, allowing it to handle any weather condition on any terrain.
