Abstract
A method is provided for controlling a low speed operation of a vehicle. A speed activation switch is activated. A target vehicle speed is calculated in response to an accelerator pedal demand as determined by an accelerator pedal position where each respective accelerator pedal position is associated with a respective predetermined target vehicle speed. A vehicle turning geometry is determined in response to a steering wheel angle input. A target wheel speed of each of a plurality of vehicle wheels is calculated as a function of the target vehicle speed and turning geometry. An actual wheel speed of each wheel is measured. A net torque is determined in response to the target wheel speeds and actual wheel speeds. An engine output torque and a braking torque are determined in response to the net torque. The engine output torque and the total vehicle braking torque are controlled for cooperatively maintaining the target vehicle speed.
