Title:
センサ誤差補正装置、及びセンサ誤差補正プログラム
Document Type and Number:
Japanese Patent JP7238490
Kind Code:
B2
Abstract:
To obtain a sensor error correction device and a sensor error correction program capable of correcting inclination in a left and right direction and acceleration of a vehicle with high accuracy even in the case that a vehicle body is inclined in an inverse direction of a turning direction due to influence of a reversing bank, centrifugal force, or the like.SOLUTION: A sensor error correction device includes: an acquisition part 31 for acquiring travel information including a value detected from each of an angular velocity sensor 11, an acceleration sensor 12, and a wheel speed sensor 13 mounted on a vehicle 10; an estimation part 32 for estimating a first angle change amount showing a rotation amount in a pitch angle direction by using the value detected from the angular velocity sensor 11 of the travel information, and a second angle change amount showing the rotation amount of in the pitch angle direction by using the values detected from the acceleration sensor 12 and the wheel speed sensor 13 of the travel information; and a correction part 33 for deriving an error of the travel information from difference between the first angle change amount and the second angle change amount, and correcting the travel information acquired by the acquisition part 31 on the basis of the error.SELECTED DRAWING: Figure 3
