Access control system for a work vehicle
First Claim
1. A method for controlling access to a work vehicle having an operating control system including an engine system, a transmission system and an auxiliary fluid actuator system, the work vehicle being accessible with a control key and a transponder, the method comprising:
- transmitting data indicative of an authorized degree of access to the operating control system on the vehicle from the transponder;
comparing the transmitted data with data stored in the vehicle operating control system to determine the authorized degree of access to the work vehicle;
limiting access to the work vehicle if a proper level of access is not authorized by the transmitted data by disabling at least two systems of the work vehicle; and
activating the work vehicle using the control key.

Abstract
A system and method for controlling access to a work vehicle includes limiting an unauthorized operator'"'"'s access to the work vehicle by disabling an engine subsystem and additionally limiting access to another vehicle system such as an auxiliary fluid actuator, by disabling at least one of the auxiliary fluid actuators. In this manner, even if a thief hot wires the engine of the work vehicle, he will not be able to use the work vehicle since the engine and the fluid actuators and the fluid controller that controls the actuators are independently disabled.

6. A control system for controlling access to a work vehicle having an engine with engine subsystems, a transmission, and an auxiliary fluid controller coupled to and configured to control a plurality of fluid actuators, the control system comprising:
-
a control switch on the work vehicle;
a control key configured to operate the control switch;
a transponder coupled to the control key and containing data indicative of an authorized level of access to the work vehicle;
a vehicle control system coupled to the control switch and in electronic communication with the engine, the transmission and the auxiliary fluid controller;
wherein the transponder is configured to transmit data indicative of an authorized level of access to the work vehicle control system, and the vehicle control system is configured to responsively compare the transmitted data with data stored in the vehicle control system to determine the authorized level of access and to responsively limit access to the work vehicle by disabling at least one subsystem of the engine and to responsively and additionally limit access to one of the transmission and at least one of the auxiliary fluid actuators by disabling at least one of the transmission and auxiliary fluid actuators. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
