Title:
SHIFT CONTROL DEVICE FOR AUTOMATIC TRANSMISSION
Document Type and Number:
Japanese Patent JPH08152062
Kind Code:
A
Abstract:

PURPOSE: To provide a shift control device for an automatic transmission which is constituted in such a manner that by releasing a shift hold control under a given condition, even during cornering, the feeling of physical disorder of a driver is prevented from generation and drivability of a vehicle is improved.

CONSTITUTION: A speed change control device for an automatic transmission comprises a curve running detecting means A to detect the curve running state of a vehicle; a means B to hold a speed during cornering to forcibly hold a speed at a constant value while the curve running state of a vehicle is detected by a curve running detecting means A; and a running resistance detecting means C to detect a value related to running resistance of a vehicle. A first speed holding releasing means D is provided to release holding of a speed by the means B to hold a speed during cornering when a value related to running resistance detected by the running resistance detecting means C exceeds a first given value while a speed is held by the means B to hold a speed during cornering. When running resistance exceeds a given value, speed holding control is released and by allowing kick down, vehicle running performance is improved.
