Abstract
Abstract It is an object of the present invention to provide a method of controlling the automatic transmission of a vehicle, in which the vehicle can be smoothly started on a low frictional coefficient road by requiring the concurrent operation of the brake pedal and the acceleration pedal. An up-shift operation will occur when both the brake and acceleration pedals are operated when the vehicle speed is less than a predetermined value.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
53 words
A method of controlling an automatic transmission for a vehicle comprising the steps of: changing an automatic speed change according to a travelling condition of the vehicle; and up-shifting the automatic transmission when a brake device and an acceleration pedal have been operated when a vehicle speed is less than a predetermined value.
Claim 2
Independent Claim
53 words
A method of controlling an automatic transmission for a vehicle comprising the steps of: changing an automatic speed change according to a travelling condition of the vehicle; and up-shifting the automatic transmission when a brake device and an acceleration pedal have been operated when a vehicle speed is less than a predetermined value.
Claim 3
Dependent Claim
86 words
A method for controlling an automatic transmission for a vehicle according to claim 1, wherein whether the acceleration pedal has been depressed or not is based on a throttle opening degree of an engine, and said up-shifting occurs when the brake device has been operated when a vehicle speed is less than the predetermined value and the throttle opening degree is within a range between a predetermined lower opening degree near a fully closed position and a predetermined higher opening degree near a fully opened position.
