Using driving behavior to determine gear changes of an automatic transmission
First Claim
Patent Images
1. A method for establishing a gear shift schedule, comprising:
- (a) developing shift schedules and a current value representing driving behavior;
(b) using gear selector movement to determine a driving mode having a base;
(c) updating, using a controller, the current value by adding a first value determined from a difference between the current value and the base, and values determined from evaluations of current driving behavior;
(d) establishing a current shift schedule based on the updated current value and the shift schedules.

Abstract
A method for changing the timing of gear changes of an automatic transmission for a motor vehicle including repetitively updating a current value of a count whose value is a measure of driving behavior, performing an evaluation of driving behavior and updating the current value by a value determined from the evaluation, determining shift schedules that define the occurrence of a gear change to be produced by the transmission, and using the updated current value to establish from among the shift schedules a shift schedule that defines a gear change to be produced by the transmission.

13. A method for adjusting a schedule that defines conditions at which gear changes of a transmission occur, comprising:
-
(a) repetitively updating, using a controller, a current value of a count using a first value determined from a difference between the current value of the count and a base value of a driving mode determined from movement of a gear selector; (b) performing evaluations of driving behavior and updating the current value of the count by a value determined from the evaluations; (c) developing shift schedules that define gear changes able to be produced by the transmission; and (d) establishing a current shift schedule based on the updated current value of the count and the shift schedules. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
