Patent ID: 7536854

Claim:
A method of regeneration of a motor vehicle particle filter, in which a device configured for regeneration of the filter is used as soon as a load value of the filter exceeds a predetermined threshold, comprising: calculating a parameter representing operating conditions of the device configured for regeneration; and controlling operation of the device configured for regeneration in accordance with a value of the parameter wherein the parameter representing the operating conditions of the device configured for regeneration includes a ratio of a flow of exhaust gases emanating from an engine of the vehicle and a measurement of a mass of soot burned during use of the device for regeneration over a predetermined period of time, wherein said mass of soot is determined from the equation: M ( i+ 1)= M ( i )− V ( i ), in which: M(i) designates the mass of soot at instant i, and V(i) designates the rate of regeneration at instant i.
