Autonomous vehicle braking and steering system

摘要

A steering system for a vehicle (10) includes a front wheel (12, 14) supported for rotation about a first axis (34) and a pivot axis (36) transverse to the first axis (34) and spaced inboard of a centerline (40) of the front wheel (12, 14). The front wheel (12, 14) is movable about the pivot axis (36) to change direction of the vehicle (10). A brake (26) coupled to the front wheel (12, 14) provides braking rotation of the front wheel (12, 14) and a controller (28) controls operation of the brake (26) to generate a desired braking force in a direction determined to adjust a vehicle direction.
