Vehicle motion measurement apparatus, a vehicle abnormal motion prevention apparatus and a drive recorder
First Claim
1. A vehicle motion measurement apparatus comprisinga 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 by a processor at least one vehicle parameter that does not change by the driving condition of the vehicle;
a sideslip angle temporary estimator for computing by the processor a sideslip angle temporary estimated value from a first 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 by the processor 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.

Abstract
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.
