Title:
VEHICLE SPEED CONTROL MECHANISM OF WORK VEHICLE
Document Type and Number:
Japanese Patent JP2002340182
Kind Code:
A
Abstract:
To provide a work vehicle for safely traveling in a place such as a slope on which an attitude of a work vehicle body happens to become unstable during traveling.
Ground angles in the longitudinal and lateral direction are detected by inclination sensors 105a and 106a. Risk is arithmetically determined from an attitude and the speed of the work vehicle. Thereby, a traveling speed is reduced according to the risk by using a continuously variable transmission mechanism 23 automatically controlled by a control controller 110. When the risk is remarkably high, a target speed is set to zero, and travel of the work vehicle is stopped.
