A control method for an automatic transmission (1) in which a first and a second control system (22, 24) are provided and regulate the transmission ratio respectively in automatic and in manual mode. The method comprises the stages of activating (100) the first control system (22) and automatically setting a transmission ratio, detecting the presence (110) of a manual command from an operator to modify the transmission ratio in use, performing (130) the manual command from the operator by modifying the transmission ratio set automatically, silencing (130) the first control system (22) for a predetermined time interval (Tsleep) such that the transmission ratio set following the manual command is not modified following any automatic gear change request from the first control system (22), and attributing (100) the control of the automatic transmission to the first control system (22). <IMAGE> |
