    摘要: The apparatus and method of the present invention improves precision of measuring a yaw rate by mutually making up for a drawback of a yaw rate sensor for directly measuring the yaw rate and a drawback of a structure for estimating the yaw rate. An estimated yaw rate operation element (51) gives an estimated yaw rate γe based on a steering angle θf of front wheels, a vehicle speed V, a left front wheel speed vFL, and a right front wheel speed vFR measured by respective sensors (41-47). A low-pass filter (53) eliminates a high frequency component included in the signal of estimated yaw rate γe, while a high-pass filter (55) eliminates a low frequency component included in a signal of measured yaw rate gs measured by a yaw rate sensor (49). An adder (57) compounds an output signal of the low-pass filter (53) with an output signal of the high-pass filter (55). A resulting yaw rate output from the adder (57) includes a component of the estimated yaw rate γe in a low frequency domain where the yaw rate sensor has large or serious measurement errors due to a zero-point drift or the like, and a component of the measured yaw rate gs in a high frequency domain where the estimated yaw rate has large or serious estimation errors.

    摘要: 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 (x̂ 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 (12 1 , ..., 12 n ), 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 (12 i ) from said plurality of complementary filters (12 1 , ..., 12 n ).

    摘要: A turning-characteristic estimating unit 11 of an ECU 1 estimates a stability factor Kh and a steering-response time constant coefficient Tp that are parameter values related to turning characteristics of a vehicle 10. A standard yaw rate YrStd of the vehicle 10 is calculated using the estimation values of the stability factor Kh and the steering-response time constant coefficient Tp estimated by the turning-characteristic estimating unit 11. A validity determining unit 12 of the ECU 1 determines the validity of the estimation values based on the standard yaw rate YrStd and an actual yaw rate Yr of the vehicle 10. This allows improving the estimation accuracy of the stability factor Kh and the steering-response time constant coefficient Tp.
