Abstract
A power control system for use with an engine which is connected through a torque converter to a transmission includes a speed ratio calculating device for determining the speed ratio of the torque converter, a torque ratio calculating device for determining the torque ratio of the torque converter from the speed ratio, a capacity factor calculating device for determining the capacity factor of the torque converter on the basis of the speed ratio, an input torque calculating device for determining an input torque to the transmission by making use of the torque ratio and the capacity factor, a detection device for detecting an overtorque state by comparing the torque to be applied to the component of the transmission mechanism or a drive mechanism in accordance with the input torque with an allowable torque predetermined for the component, and an output device for outputting a signal to engine torque control device to drop the output torque of the engine in case the overtorque state is detected.
