摘要： PROBLEM TO BE SOLVED: To provide a cart in which each wheel is driven independently in which reduction in acceleration/deceleration efficiency is suppressed in minimum level and generation of yawing torque is suppressed.SOLUTION: A rotational angular velocity detector 40 detects rotational angular velocity ω1 to ω4 of each of wheels and a racing/slipping detection part 50 determines whether each of the wheels is in a racing/slipping state or not. In addition, a load torque estimating observers OBS1 to OBS4 calculate load torque estimation values T1, T2. Furthermore, if it is determined that at least one wheel among the a pair of right and left wheels is in racing/slipping state, an adhesion-recover controlling part 60 defines the minimum value among absolute values of load torque estimation values T1, T2 for the right and left wheels as a holding torque minimum value and outputs values calculated by multiplying the holding torque minimum value by a correction constant as torque instructions T1, T2 for both wheels.

摘要： PROBLEM TO BE SOLVED: To provide an on-vehicle branching system capable of eliminating the confirmation time for point switching and time-lag of switching.
SOLUTION: When a vehicle position is positioned at this side more than a branched part, a stepping surface 3b of a wheel 3 is placed on a rail as shown in Fig.(a). Further, when the wheel 3 travels to the point part, flange parts 3a of the left and right wheels 3 ride up on flange way parts 4 and the stepping surface 3b is separated from the rail 1 as shown in Fig.(b). By riding up on the flange way parts 4, restriction in the traveling direction of the vehicle by the rail is eliminated. A driver or a computer determines whether the vehicle linearly advances along a roadway A or turns along a roadway B and steers the wheel by a mechanism mentioned later.
