Abstract: An electric motor control system for a vehicle includes a vehicle speed module that determines a vehicle speed. A closed loop (CL) module determines a CL torque based on a difference between a target vehicle speed and the vehicle speed. A motor torque module determines a motor torque based on the CL torque and a motor torque request determined based on a position of an accelerator pedal. A switching control module controls switching of an inverter based on the motor torque to control application of power to an electric motor of the vehicle.

Abstract: A road load module is configured to determine a road load torque to maintain zero vehicle acceleration. A closed loop (CL) module is configured to determine a CL torque based on a difference between a target vehicle speed and a vehicle speed. A motor torque module is configured to: produce a limited CL torque by limiting the CL torque to a predetermined torque limit when a magnitude of the CL torque is greater than a magnitude of the predetermined torque limit; when the vehicle speed is within a predetermined low speed range and a magnitude of the road load torque is greater than or less than a magnitude of a predetermined maximum torque, adjust the predetermined torque limit; and determine a motor torque command based on the limited CL torque and a motor torque request determined based on a position of an accelerator pedal.

Abstract: An electric motor control system for a vehicle includes a vehicle speed module that determines a vehicle speed. A target speed module selectively transitions a target vehicle speed to zero over a period in response a driver actuating an input device. The input device is not an accelerator pedal or a brake pedal. A switching control module, based on a difference between a target vehicle speed and the vehicle speed, controls switching of an inverter to control application of power to an electric motor of the vehicle.
