METHOD AND DEVICE FOR CONTROLLING AN AUTOMATIC FREEWHEELING FUNCTION IN A VEHICLE |
摘要 |
A method and device for controlling an automatic freewheeling function in a vehicle where a freewheeling function is active due to a prevailing freewheeling condition and where a control unit is programmed to: predict that the vehicle soon will travel in a steep downhill slope that is steeper compared to a prevailing downhill slope; simulate if less fuel will be consumed if the freewheeling function is inactivated in a a further position before the vehicle enters the steeper downhill slope, compared to if the vehicle enters the steeper downhill slope with the freewheeling function active; and inactivate the freewheeling function in the further position, that is, before the vehicle enters the steeper downhill slope if the simulation shows that less fuel will be consumed.
