ABSTRACT:
A change gear control device for an automatic transmission in a motor vehicle comprising, an acceleration sensor which detects an acceleration on the motor vehicle into its traveling direction; a vehicle traveling speed detector; a controller for processing change gear ratio for the automatic transmission which reads a detected acceleration from the acceleration sensor, a detected vehicle traveling speed and further the instant transmission gear ratio from the automatic transmission, calculates an engine torque based upon the acceleration and the instant transmission gear ratio, determines a new transmission gear ratio based upon the calculated engine torque and the vehicle traveling speed, and outputs a signal representing the new transmission gear ratio to the automatic transmission; a further acceleration sensor which detects an acceleration acting on the motor vehicle in its lateral direction; and an arrangement for inhibiting the signal representing the new transmission gear ratio from the change gear ratio processing controller to the automatic transmission when a lateral acceleration acting on the motor vehicle detected by the further acceleration sensor exceeds a predetermined reference value.
