When the vehicle (100) is in motion and is approaching a downgrade, determining whether the engine (101) can be disconnected from the driveshaft (104, 105) for at least a first period of time (T1), and disconnecting the driveshaft (104, 105) for at least the first period of time (T1); and the engine (101) also is switched off for the first period (T1). A system that performs the method and a vehicle that performs it are disclosed. |
