DEVICE FOR ESTIMATING TURNING CHARACTERISTIC OF VEHICLE |
摘要 |
A device for estimating turning characteristic of a vehicle estimates a stability factor indicating the turning characteristic of a vehicle. The device for estimating the turning characteristic calculates the transient yaw rate of a vehicle involved in the relationship of a primary delay relative to the steady-state normative yaw rate of a vehicle, and calculates the deviation between the transient yaw rate of the vehicle and the actual yaw rate of the vehicle. The device for estimating the turning characteristic corrects the estimated value of the stability factor so as to approach the true stability factor by correcting the initial value of the stability factor supplied to the calculation of the normative yaw rate of the vehicle on the basis of the relationship between the deviation of the yaw rate and the lateral acceleration of the vehicle so that the transient yaw rate of the vehicle approaches the true yaw rate. |
