Abstract:
1. A computer-implemented method of controlling a vehicle powertrain, comprising: detecting a condition when a brake input and an accelerator input occur simultaneously; determining a magnitude of the brake input; and commanding the powertrain to decrease engine torque output directly proportional to the magnitude of the brake input when the condition is detected, wherein the step of commanding includes determining a baseline output, which is a function of a magnitude of the accelerator input, and subtracting a decrease in output, which is a function of the magnitude of the brake input; wherein the magnitude of the brake input can be characterized according to a lower range and a higher range; wherein when the magnitude of the brake input is in the lower range commanding the powertrain to decrease output according to a first relationship; and wherein when the magnitude of the brake input is in the higher range commanding the powertrain to decrease output according to a second relationship.
