摘要
The invention relates to a method for determining service intervals for a motor vehicle fitted with an exhaust gas treatment system, the treatment consisting in selective catalytic reduction, in a catalytic converter, of the exhaust gases, using a reducing agent injected into the exhaust line, the method comprising the following steps, performed upon vehicle start-up: the step of determining an initial value for the distance still to be covered before the next service, the step of determining an actual distance covered since the last start, the step of determining a quantity of reducing agent consumed since the last start, the step of determining, as a function of this consumed quantity of reducing agent, a vehicle driving harshness factor, the step of correcting the actual distance covered on the basis of the harshness factor, in order to obtain a weighted distance covered, and the step of updating, on the basis of this weighted distance covered, an updated value of the distance still to be covered before the next service.
