Monitor display method in electric vehicle

Claim 1

A method of displaying monitor information in a monitor system incorporating a control means and a display unit for effecting monitor-display, concentrating pieces of the monitor information on a plurality of inspecting/monitoring spots at a single place in an electric vehicle, the method comprising the steps of: dividing a variety of monitoring spots into groups according to every functional component of said electric vehicle; displaying said groups of said monitoring spots in the form of pictorial symbols on said display unit; indicating monitor results in said pictorial symbols; and displaying a management information message in character during a normal operation of said electric vehicle and a detailed abnormal information message in character for every pictorial symbol representation associated with said respective monitoring spots during an abnormal operation thereof.

Claim 2

A method of displaying monitor information in a monitor system incorporating a control means and a display unit for effecting monitor-display, concentrating pieces of the monitor information on a plurality of inspecting/monitoring spots at a single place in an electric vehicle, the method comprising the steps of: dividing a variety of monitoring spots into groups according to every functional component of said electric vehicle; displaying said groups of said monitoring spots in the form of pictorial symbols on said display unit; indicating monitor results in said pictorial symbols; and displaying a management information message in character during a normal operation of said electric vehicle and a detailed abnormal information message in character for every pictorial symbol representation associated with said respective monitoring spots during an abnormal operation thereof.

Claim 3

A method of displaying monitor information in a control system having a self-diagnostic function with respect to parts and equipments and incorporating a display unit for displaying self-diagnostic results in an electric vehicle, the method comprising the steps of: sequentially storing in an internal memory the names of parts or equipments as abnormal part history data which are judges to be abnormal from the self-diagnostic results in the order of the abnormalities being caused; setting a mode of displaying said abnormal part history data; and displaying said abnormal part history data on said display unit in the order of the abnormalities being caused or in the reversed order in the form of character messages or codes when setting said mode.

Claim 4

A method of displaying monitor information in a control system having a self-diagnostic function with respect to parts and equipments and incorporating a display unit for displaying self-diagnostic results in an electric vehicle, the method comprising the steps of: sequentially storing in an internal memory the names of parts or equipments as abnormal part history data which are judges to be abnormal from the self-diagnostic results in the order of the abnormalities being caused; setting a mode of displaying said abnormal part history data; and displaying said abnormal part history data on said display unit in the order of the abnormalities being caused or in the reversed order in the form of character messages or codes when setting said mode.

Claim 6

A method of displaying monitor information in an electric vehicle incorporating both a microcomputer-based control system and a display system for displaying pieces of management information and of monitor information on respective components of said electric vehicle according to outputs of said control system, the method comprising the steps: permitting said microcomputer to effect an arithmetic operation on the basis of input data upon inputting signals from operation switches and sensors of respective components of said electric vehicle or feedback signals of said respective components; outputting one of control output signals and display signals; exhibiting a normal display mode when a selective state of a mode change-over select switch attached to said microcomputer is in a predetermined position; displaying general information on the control or arithmetic results on a display unit; exhibiting an I/O condition display mode when the selective state of said select switch is in positions other than said predetermined position; and displaying on said display unit the data contents, in the form of numerals such as 1 or 0, characters or symbols, of a register of an I/O port of said microcomputer, these contents correspond to the selecting positions.

Claim 7

A method of displaying monitor information in an electric vehicle incorporating both a microcomputer-based control system and a display system for displaying pieces of management information and of monitor information on respective components of said electric vehicle according to outputs of said control system, the method comprising the steps: permitting said microcomputer to effect an arithmetic operation on the basis of input data upon inputting signals from operation switches and sensors of respective components of said electric vehicle or feedback signals of said respective components; outputting one of control output signals and display signals; exhibiting a normal display mode when a selective state of a mode change-over select switch attached to said microcomputer is in a predetermined position; displaying general information on the control or arithmetic results on a display unit; exhibiting an I/O condition display mode when the selective state of said select switch is in positions other than said predetermined position; and displaying on said display unit the data contents, in the form of numerals such as 1 or 0, characters or symbols, of a register of an I/O port of said microcomputer, these contents correspond to the selecting positions.
