PROBLEM TO BE SOLVED: To provide an inclination angle calculation device that can correct a characteristic value of acceleration sensors with high accuracy, using the acceleration sensors low in processing performance.SOLUTION: An acceleration sensor 2 comprises a first characteristic value correction unit 22 that corrects a characteristic value in a detection temperature T of a temperature sensor 1, using a primary correction expression including a characteristic value of an acceleration detection unit 21 in any two temperatures of a first temperature TC, a second temperature TL lower than the first temperature TC, and a third temperature TH higher than the first temperature TC. A microcomputer 3 comprises a second characteristic value correction unit 31 that corrects the characteristic value in the detection temperature T, using a secondary correction expression inclusive of the characteristic value in the temperature different from the primary correction expression of the first temperature TC, second temperature TL, and third temperature TH.SELECTED DRAWING: Figure 2

    【課題】処理能力の低い加速度センサを用いて、加速度センサの特性値を高い精度で補正することができる傾斜角算出装置を提供する。【解決手段】加速度センサ2は、第1温度TC、第1温度TCよりも低い第2温度TL及び第1温度TCよりも高い第3温度THのうちのいずれか2つの温度における加速度検知部21の特性値を含む1次補正式を用いて温度センサ1の検知温度Tにおける特性値を補正する第1特性値補正部22を備える。マイコン3は、第1温度TC、第2温度TL及び第3温度THのうちの1次補正式と異なる温度における特性値を含む2次補正式を用いて検知温度Tにおける特性値を補正する第2特性値補正部31を備える。【選択図】図2
