VEHICLE CONTROL SYSTEM

摘要

A control system for a tractor, wherein said control system controls an operating condition of an implement attached to attachment means on the tractor. The control system comprises a sensing means providing a force signal which is indicative of the current pull force necessary to pull the implement in a desired position. The system further comprises a control means which receives the force signal and measurement means for measuring at least one parameter associated with a tractor mode and/or an implement mode and the position of the implement is adjusted to a new position when said force signal varies. The control system comprises pre-determined parameter values associated with a tractor and/or implement mode. A measured parameter is compared with the pre-determined parameter values and if the measured parameter would result in an undesired movement of the implement attachment means, the force signal is deactivated, or the response to the force signal is deactivated to prevent undesired movement of the attachment means.
