Abstract: A battery electric system includes a battery, sensor suite, and controller. The sensor suite includes a current sensor, voltage sensor, and temperature sensor. The controller is operable for determining an estimated open circuit voltage of the battery at different time points using a current signal and a voltage signal from the current and voltage sensors, and an equivalent circuit model (ECM). The controller determines an ECM-based state of charge (SOC) of the battery at the different time points, via a calibrated SOC map, using the open circuit voltage and temperature, and calculates a sensor gain value using the ECM-based SOC and a coulomb counting-based SOC, both at the different time points. A control action is executed with respect to the battery when the sensor gain value exceeds a predetermined gain fault threshold, including generating a fault notification signal indicative of a fault of the current sensor.

Abstract: Presented are control systems for governing analog and digital radio services in motor vehicles, methods for making/using such systems, and vehicles equipped with such systems. A method of controlling a vehicle includes an in-vehicle radio tuner receiving selections of broadcast radio stations output by analog signals and/or streaming radio stations output by digital signals. A vehicle controller retrieves a memory-stored broadcast station service (BSS) map with a service contour containing available broadcast radio stations having sufficient signal strength within a designated area. The controller receives geopositional data indicative of the host vehicle's location, and accesses a remote database to retrieve an updated BSS map that corresponds to the vehicle's location. The controller then determines if the stored BSS map corresponds to the updated BSS map; if not, the radio tuner responsively displays an updated list of available stations revised to reflect available stations contained in the updated BSS map.
