PROBLEM TO BE SOLVED: To provide a trailer stable travel controlling device in a traction type snow removal vehicle, capable of certainly removing remaining snow with a sweeping brush arrange on the trailer even in work at a curve by decreasing inner ring difference. SOLUTION: The traction type snow removal vehicle is equipped with at least a traction vehicle 1 and a trailer 2. In a control processing computing device 3, a proper coupling angleθa decided by a relative relationship between a steering angleθs and a coupling angleθj is modeled, and a target rear wheel angleθn of rear wheels 22w/22w corresponding to the proper coupling angleθa is memorized in advance. A steering angle signal 12P and a coupling angle signal 13P are inputted in the control processing computing device 3. On the basis of the computed target rear wheel angleθn, a steering angle controlling signal 22Q is transmitted to a steering device 22a to steer the rear wheels 22w/22w. On the other hand, a brush angle controlling signal 21Q is transmitted to a brush angle adjusting device 21a to rotate the sweeping brush 21. COPYRIGHT: (C)2006,JPO&NCIPI
