Abstract:
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)}i) of angles of attitude (θ, φ, Ψ) of the motor vehicle as a function of input signals comprising an acceleration signal (A) and an angular-velocity signal (ω). According to the invention, the device (10) comprises a plurality of complementary filters (121, . . . , 12n), each tuned for operating in a specific dynamic range, and a supervisor unit (11), configured for recognising the dynamic range of the input signals (A, ω) and selecting a corresponding filter (12i) from said plurality of complementary filters (121, . . . , 12n).
