PROBLEM TO BE SOLVED: To increase the safety and comfort of power servo steering by preventing the overheating of a power servo steering output stage, and to simultaneously execute comfortable steering support. SOLUTION: In a method for reducing a maximum loss output Pmax generated during traveling driving in the output stage of vehicle power servo steering, recognition is made as to whether one or two or more vehicle conditions and surrounding conditions affecting the temperature of the output signal exceed danger values or not and, when the conditions exceeding the danger values are determined, the maximum loss output Pmax of the output stage is reduced according to one predetermined algorithm or two or more different algorithms preset to be selected according to a parameter formed based on the vehicle and surrounding conditions. |
