Abstract
A vehicle-position monitoring system includes liquid-capacitive inclinometer sensor, configured to provide a measurement of grade (θ) of a surface over which a vehicle travels, and an accelerometer to measure acceleration of the vehicle along a principal axis (a) of the vehicle along the surface. Direct measurement of the grade (θ) provides a position-tracking system with accurate information to extract acceleration due to motoring and braking (a) from acceleration experienced along the principal axis and track vehicle position without regard to wheel diameter calibration.
