Title:
VEHICLE MOVEMENT AMOUNT CALCULATION DEVICE, PROGRAM AND METHOD
Document Type and Number:
Japanese Patent JP2016032960
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance an estimation accuracy of a movement amount of a vehicle with respect to a vehicle movement amount calculation device, a vehicle movement amount calculation program and a vehicle movement amount calculation method.SOLUTION: An acquisition part 21, which acquires a curvature of a revolution locus calculated from a steering angle of a vehicle 1, a vehicle speed calculated from a pulse signal of a wheel speed sensor 5, and an angular speed calculated from an output signal of a yaw rate sensor 6, is provided. Further, an estimation part 26, which estimates a calibration value k corresponding to an aberration between a tire circumference length calculated based on a pulse signal and an actual tire rolling length and a drift amount m corresponding to an aberration between a yaw rate corresponding to an output signal and an actual yaw rate, on the basis of revolution geometric characteristic such that the product of a curvature by a vehicle speed is coincident with an angular speed, is provided.SELECTED DRAWING: Figure 3
