Automatically guided motor vehicle with enhanced ride comfort - employs supplementary controller to adjust damping of steering oscillations according to antenna point distance from centroid

摘要

An antenna point at a controlled distance ahead of the centre of mass of the vehicle is caused to follow a predetermined track automatically by means of a supplementary controller (3), to which provisional signals (1 star, h star), denoting steering angle adjustment and traction or braking respectively are supplied from the main position controller (1). Outputs to respective power amplifiers (5,7) and motors (9,13) are modified suitably. USE/ADVANTAGE - Vehicle guidance system. Oscillatory changes of direction on a curved course can be damped or rendered aperiodic in fully automated steering, giving greater ride comfort than is achievable with the position control alone.
