Described herein is a device for detecting the attitude of motor vehicles, which comprises using at least one filter of a complementary type for computing an estimate ({circumflex over (x)}) of angles of attitude (&#x3b8;, &#x3c6;, &#x3c8;) of the motor vehicle as a function of input signals comprising an acceleration signal (A) and an angular-velocity signal (&#x3c9;). According to the invention, the device () comprises a plurality of complementary filters () each tuned for operating in a specific dynamic range, and a supervisor unit (), that acts to recognize the dynamic range of the input signals (A, &#x3c9;) and select a corresponding filter () from said plurality of complementary filters (, . . . , 12).
