Under extreme climatic conditions, the vehicle fuel consumption can be far from the certified value. Given the growing concern for polluting emissions, it is necessary to investigate a way to improve the vehicle global efficiency and thus close the emissions and fuel consumption gap. A solution is to pre-warm the gearbox in order to make it work at optimal temperature to get the best efficiency possible. Indeed, low lubricant temperature is a source of low vehicle performance due to the viscosity exponentially rising at very low temperature. Using the Powertrain Dynamics library, a vehicle model with a detailed equation based gearbox model taking into account the temperature-dependent losses is developed.
