Latent heat storage unit A storage system that absorbs collected solar energy, transferred using steam at 200 to 300 degrees Celsius, and stores it as thermal energy with low losses and, ideally, for long periods and through many repeated cycles. Latent heat storage makes use of the ‘hidden’ energy absorbed or released when a material undergoes a phase change. This can be latent heat of fusion (melting) or latent heat of vaporisation. Latent heat storage is also referred to as phase-change storage.

Transport

 

Climate-controlled all-wheel drive roller test stand The DLR operates an all-wheel-drive roller test stand with exhaust analysis and climate control for passenger vehicles and vans. The test stand simulates driving conditions for single axle and all-wheel-drive concepts in a variable temperature range from minus 25 degrees Celsius to 50 degrees Celsius. The explosion-protected version can be used to test hydrogen and natural gas powered vehicles. The exhaust analysis allows measurements to be made with an accuracy that is suitable for checking compliance with the Euro 5 emissions standard.
Dynamic driving simulator DLR's dynamic driving simulator is being deployed to test driver assistance functions in an advanced stage of product development. The realistic design of the simulation enables a valid evaluation of the functions even in critical situations and thus a safe transition into the test vehicle and into real-life traffic. The driving simulator conveys a realistic experience by means of three components: a high-performance movement system, a high-quality projection system with corresponding visualisation and the integration of a complete vehicle.
FASCar Test vehicle for developing driver assistance systems. Active intervention can make driving on roads safer - but can become dangerous when wrongly implemented. Assistance systems must be designed according to the requirements and wants of the driver. To find out whether the driver reacts correctly to the intervention of a new assistance system, a ride in the FASCar is the final consistent step in development.
FCD Floating Car Data. Term from traffic technology: Position data from vehicles are collected with the aid of a vehicle fleet and are managed via an availability system, for example taxi fleets (Taxi FCD).
HMI Lab Human Machine Interface Laboratory. The HMI Lab is used to evaluate new driver assistance systems and functions quickly and flexibly with respect to usability and acceptance. A seat with a steering wheel and pedals is used to control the virtual vehicle, and a centre console with a touchscreen can be added to the simulation if required; however the rest of the interior of the vehicle is only simulated.
