Electronic Fan System Strategies and Statistical Life Test Method / Mission Profile

In order to improve the Thermal System Management and fulfill the need of car Manufacturers, VALEO is developing new engine cooling « intelligent » Components and Strategies.

The evolution of engine cooling strategies with the introduction of electronics in Fan System like FANTRONIC® is presented here. The use of such controlled actuators allows to reduce noise annoyances, pollutant emissions, fuel consumption and to improve comfort and engine cooling.

The tests achieved on a Mercedes A Class allow to compare different kind of engine cooling strategies on a statistical driving car use on a whole year.

This method uses three inputs: vehicle speed, air ambient temperature and air conditioning use. Outputs are electric / gas consumption and noise annoyances integrated with an equivalent noise level method.
