Abstract: A method for predicting the duration of a future charging process for a vehicle battery. The method comprises estimating a future charge amount of the battery corresponding to the start of the future charging process. The method further comprises estimating a future temperature of the battery. The method still further comprises determining a future charging power or a characteristic thereof to be applied to the battery during the future charging process, wherein the future charging power or characteristic thereof is based on the estimated future charge amount and the estimated future temperature and is representative of a charging amount or characteristic thereof that will maintain the temperature of the battery at or below a threshold temperature during the future charging process. The method still further comprises predicting a duration of the future charging process based on the estimated future charge amount and the determined future charging power or characteristic thereof.

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.
