Method for controlling automatic gearbox in motor vehicle, involves passing control toward transmission to switch to gear ratio in association with verification of conditions such as absence of air/fuel ratio control and brake control

摘要

The method involves monitoring conditions such as absence of air/fuel ratio control, absence of brake control, speed (V) of a vehicle higher than a threshold speed (SV), and acceleration (A) of the vehicle higher than a threshold acceleration (SA). A control is passed toward a transmission to switch to a gear ratio in temporal association with the verification of the conditions, where the passage of control is initiated simultaneously upon verification of the conditions.
