TRANSMISSION CONTROLLER OF VEHICLE AUTOMATIC TRANSMISSION

摘要

A transmission level appropriate to the intention of the driver of a vehicle, for example, whether or not the driver wants power source brake is set as the initial transmission level when the driver selects the manual transmission mode. When a shift lever (72) is moved to the "S" position to select the S mode, it is judged whether the transmission mode is changed or the manual transmission mode is directly selected according to whether or not the shift lever (72) stays in the "D" position for a predetermined time or more (step S2). The initial transmission levels of the S mode are determined separately when the transmission mode is changed (the decision at step S2 is YES) and when the manual transmission mode is directly selected (the decision at step S2 is NO). With this, it is judged that the driver wants power source brake when the transmission mode is changed, or it is judged that the driver doesn't want power source brake when the manual transmission mode is directly selected. Hence, an initial transmission level appropriate to the intention of the driver can be determined individually.
