Abstract
In a control system for a carriage, a pair of driven wheels are raised or lowered by an elevator section so as to suppress inclination of the carriage which would be otherwise caused due to acceleration/deceleration of the carriage. Specifically, during starting acceleration of the carriage, the driven wheels are raised so as to cancel extended amounts of springs of the driven wheels. On the other hand, during steady running of the carriage, the driven wheels are lowered by a constant amount to reduce loads applied to caster sections so that vibration applied to the carriage are reduced as a whole. During braking acceleration (deceleration) of the carriage, the driven wheels are lowered so as to cancel contracted amounts of the springs of the driven wheels.
