Abstract

A display and control for use with an engine-equipped machine apparatus comprising a computer adapted to receive operating information from the apparatus, a memory connected to the computer and operable to store reference values of the operating information, a display connected to the computer for displaying in human readable form a selected operating information and the reference value associated therewith, a control connected to the computer for changing the operating information and the reference value associated therewith to be shown by the display, and an adjustment connected to the computer and the memory for varying the reference values.

Claims

1. A control and display device for apparatus including a machine and an engine for driving the machine, said engine and said machine having a plurality of sensors connected thereto for sensing information, said device comprising a control adapted to be connected to said sensors for converting various information concerning the engine and the machine into numerical values based on the detection signals from said sensors, said control including a memory for storing a reference value for each type of said information, said device further comprising a display connected to said control for displaying alphanumeric characters or other symbols, first means for changing the display mode from one type of information to a different type, second means for adjusting the reference values in said memory, said display simultaneously displaying one type of information concerning said engine and machine, the type of that information, and the reference value for that information, the output of said control and the type of information displayed in said display being selected by the operation of said first means for changing the display mode, and both the reference values displayed in said display and stored in said memory being changed by the operation of said second means for adjusting the reference values.

2. Apparatus for use with a machine and an engine connected to drive the machine, said engine and said machine each having at least one operational mode, and a plurality of sensors connected to said engine and to said machine for sensing actual values of each of said operational modes, said apparatus comprising a control adapted to be connected to and receive information from said sensors, said control including a memory for storing reference values for each of said operational modes, and computing means for converting said information from said sensors into human readable symbols, said apparatus further comprising display means including first, second and third displays connected to said control, said first display showing an actual value of a selected operational mode in readable symbols, said second display showing a reference value of said selected operational mode in said readable symbols, and said third display identifying said operational mode, said apparatus further comprising first adjustment means for changing said first, second and third displays from one operational mode to another operational mode, and second adjustment means for changing said reference values.

3. Apparatus as set forth in claim 2, wherein said second adjustment means is operable to change said reference value of the operational mode being shown by said displays.

4. Apparatus as set forth in claim 2, and further including at least one adjustment means connected to said computing means and adapted to be attached to one of said engine and said machine for adjusting an operational mode, said computing means causing said adjustment means to adjust the actual value to said reference value of said operational mode.

5. A display and control for use with an engine-equipped machine apparatus comprising:

(a) computing means adapted to receive operating information from said apparatus,

(b) memory means connected to said computing means and operable to store reference values of said operating information,

(c) display means connected to said computing means for displaying in human readable form a selected operating information and the reference value associated therewith,

(d) control means connected to said computing means for changing the operating information and the reference value associated therewith to be shown by said display means, and

(e) adjustment means connected to said computing means and said memory means for varying said reference values.

6. A display and control as set forth in claim 5, wherein said adjustment means varies the reference value being currently shown by said display means.

7. A display and control as set forth in claim 5, and further including means connected to said computing means and adapted to be connected to said apparatus for making an operating information correspond to the reference value associated therewith.
