winEVA
communication with other systems
IT Program to analyse the fuel consumption, performance and fatigue life
Performance winEVA
■ Fuel consumption, performance, fatigue life
■ scaled : simple simulation without rotational vibration to complex dynamic of switching operation including ignition and drive train vibration
■ Real time simulation (driving simulator) is integrated
■ Test bench control
■ Driving performance diagrams stationary (tensile force, braking, switching operation)
■ Powerful post-processing
■ Company specific pre-processing based on SQL-server is available
■ Formula generator for channels created subsequently
■ Automatic batch processing
■ Data exchange with winADAM, winLIFE, EXCEL, Matlab
■ Integration of part-modules in customer‘s own Matlab Models
- Construction of Drive Train / block orientated and not fixed to topology
ing strategy / Simulation type pilot drive
Driving following a measured speed
- Only makes sense if measuring vehicle and simulation vehicle are similar
- From the pilot drive a (universal) required speed path can be generated
Driving strategy / Simulations type required speed path
Required speed path can be created from
- Data from measured drive
- Route data (curvature, traffic rules, traffic intensity)
- Provision of a cycle (e.g. NEFZ)
Influence of vehicle type on the driving following a required speed path

Research & Development Projects
Project example / establishing driving resistance / coasting test
- By measuring the acceleration when vehicle is coasting on a road as flat as possible(Nordlinger Ries) important factors can be determined fairly exactly, e.g.
- Rolling resistance
- Air resistance
Project example / coasting test
Project example / capacity measuring in traffic
- Only a certain number of vehicles can travel on one road per hour.
- With increasing driving speed, the capacity decreases.
- With an increasing number of vehicles per km, the speed decreases and ? when reaching the capacity limit ? traffic jams occur.
Project example / Road capacity
- 2 measuring vehicles travelled from Ulm to Merklingen spaced at a distance (within sight)
- The position of both vehicles was measured with GPS and from this the distance between the vehicles could be calculated.
- The number of vehicles between the two measuring vehicles was determined by video information.
- The traffic density (vehicles per km) and the average speed could be determined.
- In this way the fundamental diagram which is so important in traffic engineering, could be determined.
