A vehicular control system for automatically shifting a countershaft transmission wherein the power control means is controlled in accordance with a manually operated accelerator pedal and shift requirements. During non-shift modes of operation, the power control means is adjusted in accordance with the manually operated accelerator pedal. During a shifting mode of operation, the power control means is adjusted in accordance with the shift requirements of the transmission. Once a desired gear ratio is engaged in the transmission, the power control setting is returned to correspond with the accelerator pedal setting at a rate dependent upon their difference. Means are also provided for modifying the return rate if the accelerator pedal setting is abruptly adjusted during the return.

A method for bringing the setting of a power control means for a power source into correspondence with a manually actuated power control setting upon completion of a shifting mode of operation of a transmission that is driven by the power source wherein the power control means is regulated in accord

A method for bringing the setting of a power control means for a power source into correspondence with a manually actuated power control setting upon completion of a shifting mode of operation of a transmission that is driven by the power source wherein the power control means is regulated in accordance with (1) a manually actuated power control setting during non-shift modes of operation and (2) transmission shift requirements during shifting modes of operation, said method comprising the steps of: generating a control signal as a function of the difference between the setting of said power control means and said manually actuated power control setting upon engagement of a desired gear ratio; adjusting said power control means in a direction to bring its setting into correspondence with said manually actuated power control setting and at a rate corresponding to the value of said control signal; and resuming regulation of said power control means in accordance with said manually actuated power control setting when the setting of said power control means substantially corresponds to said manually actuated power control setting.
