摘要： Methods and systems are provided for filtering an oil dilution amount based on a current value of the oil dilution amount. In one example, filtering the oil dilution amount may include decreasing a sensitivity of filtering at lower oil dilution below a threshold; otherwise, increasing the sensitivity of filtering. The sensitivity of the filtering may be decreased by implementing a larger time constant, while the sensitivity of the filtering may be increased by implementing a smaller time constant.

摘要： A motor vehicle is disclosed having an engine driving a multi-speed gearbox via a friction clutch. The engine is arranged to drive a number of electrically controllable loads the level of load applied by each of which to the engine is controlled by an electronic controller in response to a number of inputs. When the inputs indicate that an upshift of the gearbox is to take place the electronic controller is arranged to increase the loads applied by the electrically controllable loads to the engine and when the inputs indicate that a downshift of the gearbox is to take place the electronic controller is arranged to decrease the loads applied by the electrically controllable loads to the engine thereby improving the quality of the gear change irrespective of whether it is an upshift or a downshift.
