Abstract
An input torque limiting device for an infinitely variable transmission connected to an engine, wherein the transmission can vary a speed ratio up to infinity. In the input torque limiting device, the maximum torque which can be input is computed according to the output/input speed ratio which is an inverse of the speed ratio, without adversely affecting the durability and performance of the infinitely variable transmission, and the engine torque is controlled not to exceed the maximum torque. In this way, in the infinitely variable transmission, input of an excessive torque when the speed ratio is in the vicinity of infinity is prevented.
