Land Rover has developed a sonar-based system for assessing water depth that allows the driver to make informed decisions as to whether to proceed into flooded areas.
The system utilises sensors mounted in the bumpers and wing mirrors. These are able to measure depth and by working in conjunction with inclinometers recognise whether the level is increasing or decreasing. All this information is displayed in an intuitive graphic on the central touchscreen.
On-Demand Spiked Tyres
Further allowing the concepts to adjust to changing conditions is a driver-deployable spiked tyre system. This is operated by an electro-mechanical system mounted within the tyre on the inside of the wheel; activation of the technology causes air to inflate a secondary air chamber, filling pods moulded into the tread of the tyre which contain the spikes.
Land Rover has adopted Radio Frequency Identification (RFID) technology to increase the accessibility, usability and security of the concepts.
These allow the main key fob to be left in a slot in the glovebox, which deactivates it and transfers its lock and unlock functions to the rugged RFID chip. Once the system is armed and the car secured, only that specific RFID smart tag will allow it to be unlocked and reactivate the key fob.
Future developments of the system will allow each family member to have their own smart tag, which would save their personal audio, climate, communication, safety and seating settings. Third-generation smart tags could also include biometric data that would use facial systems to increase security.
"Loved the world over for its simple, honest and distinctive design, we are determined that the new Defender will be true to its heritage while meeting the requirements of a changing global market."
