1. An electric motor control system for a vehicle, comprising:
a vehicle speed module that determines a vehicle speed;
a closed loop (CL) module that determines a CL torque based on a difference between a target vehicle speed and the vehicle speed;
a motor torque module that determines a motor torque based on the CL torque and a motor torque request determined based on a position of an accelerator pedal;
a target speed module that selectively sets the target vehicle speed based on adjusting the vehicle speed to a predetermined speed of zero in response to receipt of an input by a driver to an input device that is different than the accelerator pedal and a brake pedal; and
a switching control module that controls switching of an inverter based on the motor torque to control application of power to an electric motor of the vehicle.
