Abstract:
1. A method for controlling an input torque provided to a transmission, said method comprising: executing a first iterative search within a first range of permissible torque values to determine a first torque value based on a first cost value, the first cost value being based on a first set of powertrain measurements measured at a first time; calculating a second cost value based on a second torque value and the first set of powertrain measurements measured at the first time, the second for torque value being determined using a second set of powertrain measurements measured at a second time, the second time being prior to the first time; and selecting one of the first torque value and the second torque value based on the first cost value and the second cost value; wherein the first search function executes less than ten iteration steps; and wherein at a ninth iteration step a torque value candidate tolerance level is less than +/−6 Newton-meters.
