| 摘要 |
The system of the invention comprises a gyroscope having two degrees of freedom fixed to a carriage of the vehicle and having a first axis of sensitivity disposed in the longitudinal direction of the carriage and a second axis of sensitivity disposed in the vertical direction; the gyroscope is operable to generate a first signal indicative of the angular velocity omega x about a first axis disposed in the said longitudinal direction and a second signal indicative of the angular velocity omega z of the carriage about a second, vertical axis; the system further includes a tachometric detector operable to generate a signal indicating the speed v of the vehicle and at least one integrator operable to integrate the first said signal to generate a signal indicating the angle of rotation phi x of the carriage about the longitudinal axis; a microprocessor forms the product of the signal indicating the angle of rotation and the acceleration due to gravity g and the product of the signal indicating the speed v and the signal indicating the angular velocity omega z and finally takes the difference between the second product and the first in such a way as to obtain a signal indicating the non-compensated transverse acceleration.
