Claim 8:
9. A slip determination system comprising:
a traveling vehicle body;
a vehicle position detection module for detecting a vehicle position;
an automatic travel control portion for enabling automatic travel based on the vehicle position and a set travel path;
a slip amount calculation portion for calculating a slip amount of the traveling vehicle body, using an estimated movement distance of the traveling vehicle body calculated based on the number of revolutions of a driving axle of the traveling vehicle body, and an actual movement distance of the traveling vehicle body calculated based on the vehicle position;
an appropriateness determination portion for performing appropriateness determination to determine, based on the slip amount, whether or not a state of a traveling ground surface is appropriate for automatic travel and for determining, if the slip amount exceeds an allowable slip amount, that the state of the traveling ground surface is not appropriate for automatic travel;
an automatic travel stop portion for stopping automatic travel enabled by the automatic travel control portion, based on a determination result from the appropriateness determination portion; and
a turning performance adjustment portion for adjusting turning performance of the traveling vehicle body,
wherein if the slip amount exceeds a predetermined value, the turning performance adjustment portion adjusts the turning performance without the automatic travel stop portion stopping automatic travel.
