Display system for automatic transmissions
First Claim
1. A display system for an automatic transmission which has a first range switching mechanism for switching a shift range by mechanical means and a second range switching mechanism activated by electric enabling means for switching the shift range by electric means, comprising:
- first display means for displaying the shift range which is selected by said first range switching mechanism;
second display means for displaying the acting state of said enabling means; and
third display means, which is different from said first display means, for displaying the shift range which is selected by the second range switching mechanism activated by said enabling means,wherein said first display means and said third display means simultaneously respectively display the shift range which is selected by said first range switching mechanism and the shift range which is selected by the second range switching mechanism, which shift ranges displayed by said first and third display means may be different from one another.

Abstract
A display system for an automatic transmission including: a first range switching mechanism for switching a shift range by a mechanical operation; and a second range switching mechanism activated by electric enabling mechanism for switching the shift range by an electric operation. The display system comprises: a first display device for displaying the shift range which is selected by the first range switching mechanism; a second display device for displaying the active state of the enabling mechanism; and a third display device for displaying the shift range which is selected by the second range switching mechanism activated by the enabling mechanism.

4. A display system for an automatic transmission enabled to switch a shift range by electric means, comprising:
-
fail display means for displaying that the switching of the shift range by said electric means is disabled by a failure; and switching interrupt display means for displaying that the switching of the shift range by said electric means is temporarily unable to be switched on the basis of a running state and for displays an operation to cope with the temporary inability to switch the shift range. - View Dependent Claims (5)

6. A display system for an automatic transmission which has a first range switching mechanism for switching a shift range by mechanical means and a second range switching mechanism for switching the shift range by electric means, comprising:
-
electric switching inhibition detecting means for detecting that the switching to an engine braking range by said second range switching mechanism is unable; and manual switching display means for making a display to urge the switching to the engine braking range by said first range switching mechanism, when it is detected by said electric switching inhibition detecting means that the switching to the engine braking range by said second range switching mechanism is unable. - View Dependent Claims (7, 8, 9)
