摘要： A method is provided for controlling power supply of an electrically powered steering system on-board an automotive land vehicle equipped with a high voltage source and a low voltage source. A first and a second steering motor 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. A step-up circuit is connected to the low voltage source, and is adapted to deliver a back-up electrical power in case of failure of the high voltage source. In the method, in case of failure of the high voltage source, back-up electrical power absorbed by each of the two motors is limited on the basis of a priority rule.

摘要： This internal combustion engine includes a plurality of cylinders, an air intake line, and an exhaust line. The internal combustion engine also includes a turbocharging system having at least one compressor stage and intake air cooling arrangement having at least one charge air cooler located upstream from the intake manifold. The internal combustion engine further includes an exhaust gas recirculation (EGR) line rerouting a portion of the engine's exhaust gas into the air intake line at a point located upstream from the at least one charge air cooler. This engine therefore uses an heat exchanger to cool the EGR gas. Thus, EGR gas mixed with intake air flows through at least one change air cooler before entering the engine cylinders. The efficiency of this cooler—generally of the air/water type—makes it possible to significantly decrease the EGR gas temperature before it enters the cylinders. Less cooling power from the engine cooling system is required to cool down the EGR gas as fresh intake air is used as a cooling medium in the heat exchanger.
