Abstract

L'invention concerne un procédé permettant d'avertir le conducteur d'un véhicule automobile en cas de perte d'attention, de même qu'un système d'avertissement correspondant. L'invention vise à ce que ces systèmes soient mieux acceptés par les conducteurs. A cet effet, le conducteur est surveillé quant à une perte d'attention en même temps que sont déterminées les conditions de conduite instantanées du véhicule et, si une perte d'attention du conducteur est constatée, un signal d'avertissement ne sera émis que dans certaines conditions de conduite, et ne le sera pas dans d'autres.
