Abstract

The present invention relates to an apparatus for setting a function of switches of a construction vehicle, enabling a construction vehicle driver to freely set or arrange the switches as desired, so that the driver feels more convenient to use the switches and thus, the work efficiency can be improved. Preferably, the apparatus includes a plurality of switches for generating an on/off signal; a controller for receiving a signal from the switches and outputting a driving signal to drive the work equipments; a plurality of driving units for driving the work equipments; a memory for storing relations between the switches and the driving units driven by the switches; and a pattern editing unit which includes a display screen and a plurality of input buttons, whereby a construction vehicle driver can change the relations between the switches and the driving units, the relations being stored in the memory.

Claims

1. In a construction vehicle having work equipments, the improvements comprising apparatus for setting functions of switches of the construction vehicle, the apparatus comprising:

the switches for providing respective on/off signals;

a controller for receiving the on/off signals and outputting driving signals;

a plurality of driving units for respectively driving the work equipments of the construction vehicle, the driving units being driven by the driving signals;

a memory in the controller for setting relations between the switches and the driving units; and

a pattern editing unit including a display screen and a plurality of input buttons for changing the relations between the switches and the driving units set in the memory.

2. The apparatus according to claim 1, wherein the controller comprises:

a plurality of input ports to which on/off signals of the switches are inputted;

a plurality of output ports connected to the respective driving units; and

a CPU for outputting a signal from the input port to corresponding output port thereof according to the relations stored in the memory.

3. The apparatus according to claim 2, wherein each of the driving units comprises:

an amplifier connected to the output port for amplifying a driving signal from the controller; and

a driving valve being driven by the amplified signal, and driving the work equipment.
