Abstract

A process is provided for regenerating an exhaust gas after-treatment device in an exhaust line of an internal combustion engine arrangement, the exhaust line including a particle filter. The process includes identifying when soot loading of the particle filter exceeds a predetermined level. After that, temperature of exhaust gases at the particle filter is maintained within a first temperature range until at least one of a predetermined period of time has lapsed or a determination is made that soot loading of the particle filter is below the predetermined level. After that, the temperature of the exhaust gases at the particle filter is increased to within a second temperature range above the first temperature range. An internal combustion engine arrangement is also disclosed.

This method is for controlling power supply of an electrically powered steering System on-board an automotive land vehicle (T) equipped with a high voltage source (44) and a low voltage source (48), wherein a first and a second steering motor (10) operate at a nominal operating voltage which is higher than the voltage of the low voltage source, are fed by the high voltage source and may absorb respectively a first and a second nominal operating power, and wherein a step-up circuit (50) is connected to said low voltage source (48), and is adapted to deliver a back-up electrical power in case of failure of said high voltage source (44). In the method, in case of failure of the high voltage source (44), back-up electrical power absorbed by each of the two motors (10, 20) is limited on the basis of a priority rule.
