Abstract:
1. A method of estimating quantities that represent the state of a vehicle, comprising the steps of: setting initial values to characteristic values related to vehicle characteristics; calculating required quantities that represent the state of a vehicle or values related to said required quantities that represent the state of the vehicle by applying said initial values to a prescribed movement equation; detecting measurable quantities that represent the state of the vehicle by sensors; verifying said required quantities that represent the vehicle state or values related to said required quantities that represent the vehicle state, calculated by said movement equation, using detected values of said measurable quantities that represent the vehicle state for obtaining deviations between calculated values and detected values; and correcting said initial values according to the results of said verification for obtaining adjusted values of said initial values with which the deviations between the calculated quantities and the measured quantities become zero.
