Abstract
The invention relates to a vehicle having steerable axles. A track guide icle comprises at least one pair of independent wheel axles, and at least two members (14, 15) for measuring the transverse position of the vehicle relative to the track, and it is characterized in that it includes at least one measuring member (20) for measuring the angle of the axles relative to references related to portions of the vehicle, and at least two actuator members (21) for correcting said angles by bearing against said axles, and a servo-control circuit receiving the signals from said measuring members and generating control signals for said actuator members.
