A road load module is configured to determine a road load torque to maintain zero vehicle acceleration. An initialization module is configured to determine an initial torque based on the road load torque. A closed loop (CL) module is configured to: when a CL state transitions from an inactive state to an active state, set a CL torque to the initial torque; and when the CL state is in the active state after transitioning to the active state, adjust the CL torque based on a difference between a target vehicle speed and a vehicle speed. A motor torque module is configured to determine a motor torque command based on the CL torque and a motor torque request determined based on an accelerator pedal position. A switching control module is configured to, based on the motor torque command, control switching of an inverter and apply power to an electric motor.
