<p>PROBLEM TO BE SOLVED: To provide a column travel device by which travel is realized without damaging the followup ability of a subsequent vehicle. SOLUTION: A column travel device causing a leading vehicle S which is manually driven by a driver and plural subsequent vehicles K which automatically follow up the leading vehicle S and travel in a column is provided with a manipulated variable detection means 5 detecting the driving manipulated variable of the leading vehicle S, a comparison means 6 comparing the driving manipulated variable of the leading vehicle S, which is detected by the manipulated variable detection means 5 with a threshold corresponding to a limit manipulated variable which the subsequent vehicle K can follow. When the driving manipulated variable of the leading vehicle S exceeds the threshold as the result of comparison by the comparison means 6, warning is given to the leading vehicle S.</p> |
