Abstract
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.
