Abstract
A method for controlling a car with a parallel hybrid system comprising at least a combustion engine and an electrical machine in P- or P-configuration, with a clutch for connecting the combustion engine's output shaft with at least one drive shaft. Steps include determining a power demand P, and decoupling the combustion engine from the drive shaft if the power demand Pis below a first threshold P. Coupling the combustion engine with the drive shaft when the power demand Pis above the first threshold Pprovides additional fuel savings when the method further comprises shutting off the combustion engine and providing power to the drive shaft by providing electrical power to the electrical machine to drive the car, when the power demand Pis between the first threshold Pand a second threshold P. The second threshold Pis greater than the first threshold P, i.e. if P<P<P.
