A system and method for replacing an original linear object with an updated linear object. In a flash memory or other memory device storing groups of data objects, in replacing a linear object with an updated linear object of the same size, the present invention overwrites the original linear object in the same memory space as the original version. As a result, updating the data requires erasing and writing of the block of flash memory cells where the data object is stored. A copy of the original linear object is stored so that the original version of the linear object is available for undoing the update and/or facilitating recovery if the updated linear object becomes corrupted.

In a control device for an internal combustion engine (E) of a vehicle comprising a particulate filter (42) installed in an exhaust passage of the engine and a loading device (63) that applies a load to the engine, the control device (9) is configured to execute a regeneration process for regenerating the particulate filter under a prescribed condition. When a vehicle is in a congested state, the temperature of the particulate filter typically drops below a threshold level for enabling a regenerating process. However, according to the present invention, the particulate filter may be regenerated even when the vehicle is in a congested state if a loading device such as an air conditioner is activated, and the temperature of the particulate filter is therefore high enough. Thereby, the particulate filter may be actively regenerated whenever possible.

A method for regenerating a soot-laden particle filter in the exhaust gas train of a diesel engine in a vehicle, wherein the engine is equipped with a fuel injection system having an injection valve for each cylinder and an exhaust braking device including a butterfly valve in the exhaust gas train upstream of the particle filter. An exhaust braking phase is initiated by closing the butterfly valve, thereby causing hot exhaust gas to be compressed upstream of the butterfly valve. Regeneration of the particle filter is then initiated by injecting diesel fuel into the cylinders substantially after the respective pistons pass top dead center, and allowing the hot exhaust gas mixture containing unburned fuel and air to flow past the butterfly valve so that the mixture ignites the soot and then supports combustion of the soot, thereby regenerating the particle filter.
