  • Patent number: 10317421
    Abstract: A positioning apparatus includes: a reference device configured to provide a measured current motion angle of a vehicle; an inertial sensor configured to provide a current input angular rate of the vehicle and associated with at least one inertial sensor behavior parameter dependent on inertial sensor temperature; a temperature sensor configured to provide an input temperature variation of the inertial sensor on a time interval; and a digital estimator configured to recursively computing an estimated current motion angle of the vehicle and at least one previously estimated inertial sensor behavior parameter as function of: the measured current motion angle, a previously estimated motion angle, the current input angular rate, and the input temperature variation.

  • Patent number: 10234292
    Abstract: A positioning apparatus of a vehicle includes a measuring module and a triaxial orientation sensor to provide measured axial accelerations in a Cartesian reference system during a certain time interval. The apparatus also includes a triaxial movement sensor to supply at least one angular variation signal proportional to the axial angular speed of the vehicle during the time interval. A processing unit receives a distance signal proportional to the distance traveled by the vehicle in the time interval, receives the at least one angular variation signal, and supplies at least one reference acceleration of the vehicle. An estimator-calibrator block recursively estimates at least one calibrated acceleration as a function of the measured axial accelerations and of the at least one reference acceleration.

  • Publication number: 20190033466
    Abstract: In an embodiment, a system for land vehicle navigation includes: a GNSS receiver providing GNSS data, a set of sensors positioned on a wheel of a vehicle and on board the vehicle; and a processing unit. An on-wheel unit is located on the wheel of the vehicle, the on-wheel unit including a first subset of sensors. An on-board unit includes a second subset of sensors configured to generate a second sensor data. The processing unit is configured to process the first and second sensor data to obtain the distance and the attitude of vehicle and to perform a fusion with the GNSS data.
