Driveline Simulation

Measurement while vehicle testing

With our winADAM measurement system, we determine collectives through vehicle measurements in road tests. With our MB CLA 180 d Shooting Brake measurement vehicle, we perform driving tests according to customer orders and determine the route data (topography, curvature), traffic parameters (traffic environment, density, type of journey (unimpeded, following, convoy)), driving parameters (speed, position, distance, accelerations, etc.) and drive parameters ( rpm, torque, gear, injection quantity, etc.). If required, we can procure any desired vehicle and equip it for driving tests. This also applies to commercial vehicles or construction machinery.

Simulation of vehicles

Collectives can also be determined by means of powertrain simulation of any vehicle. With our modular powertrain simulation tool winEVA, any powertrain can be set up. The range extends from e-bikes to cars to rail vehicles and from combustion engines to e-motors. With our flexible driver model in winEVA, any driver type can also be parameterised.

Any synthetic routes or measured routes can be used as routes.
