US20090276114: Vehicle Motion Measurement Apparatus, a Vehicle Abnormal Motion Prevention Apparatus and a Drive Recorder
6 Claims, 12 Drawings
The apparatus comprises a measured signal detector 11, a vehicle parameter obtainer 12, a sideslip angle temporary estimator 13, a sideslip angle differential corresponding value computer 14 and a sideslip angle real estimator 15. A sideslip angle temporary estimate value is computed from one or plural vehicle parameters including at least the mass. A sideslip angle differential corresponding value is computed from a measured signal and the vehicle parameters including no mass. A sideslip angle is derived from the sideslip angle temporary estimate value and the sideslip angle differential corresponding value. A sideslip can be detected without a steering angle detection mechanism.
- 1. A vehicle motion measurement apparatus comprising
a driving state variable estimator for detecting plural measured signals other than a steering angle which change depending on the equipped condition of a vehicle;
a vehicle parameter obtainer for obtaining at least one vehicle parameter that does not change by the driving condition of the vehicle;
a sideslip angle temporary estimator for computing a sideslip angle temporary estimated value from a fist set of parameters selected from the plural measured signals and at least one vehicle parameters including the mass;
a sideslip angle differential corresponding value computer for computing a sideslip angle differential corresponding value from a second set of signals selected from the plural measured signals and at least one vehicle parameter including no mass; and
a sideslip angle combined estimator for performing a precise estimation of a sideslip angle from the sideslip angle temporary estimate value and the sideslip angle differential corresponding value.
