Title: Control system for vehicle automatic gear transmission - has program to retain drive setting conditions if selector is moved from drive to neutral and back
Inventor: AMEMIYA SATOSHI
IPC: F16H61/00
Filed: 1993-02-18
Abstract: The transmission control has a memory to retain the drive settings after the selector control has been moved to neutral. The optimum drive settings are re-calculated while the setting is in neutral and if the selector is returned to drive, the control selects either the original settings or the newly computed settings, to reduce transmission shock. If the selector is returned to drive after only a short time in neutral, the original drive settings are reset. If the time interval is more than a set amount, a new set of conditions are selected. ADVANTAGE - Reduced transmission shock, improved drive comfort, less transmission wear.
