Inclinometer methods and systems for generating and calibrating an in-vehicle inclination angle

摘要

Provided herein are inclinometer methods and systems for generating an in-vehicle inclination angle (θ_r). An inclinometer method can include measuring an acceleration ({dot over (ν)}) of a vehicle or a vehicle member, measuring a pitch angular velocity (q) of a computer, measuring a longitudinal accelerometer signal (a_x,S) of the computer, generating an in-vehicle pitch angle (θ) of the vehicle or the vehicle member, calibrating an inclinometer-vehicle relative misalignment pitch offset angle (θ_p) of the vehicle or the vehicle member comprising a stationary-mode or a dynamic-mode, and generating an in-vehicle inclination angle (θ_r) of the vehicle or the vehicle member.
