Claim 0:
1. 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
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,
wherein the appropriateness determination portion performs the appropriateness determination based on successive behavior of the slip amount, the successive behavior being based on a statistical calculation result of average calculation or intermediate value calculation, in a predetermined period, of successively calculating a plurality of the slip amount.
