  • CHARGE OPTIMIZATION FOR CARBON EMISSIONS REDUCTION
    Publication number: 20240140238
    Abstract: An example operation includes one or more of determining, by a vehicle at a charging location, an electric grid intensity at a time period; responsive to the intensity being below a threshold, charging a battery of the vehicle; and responsive to the intensity being above the threshold, ceasing the charging of the battery; wherein the charging and the ceasing of the charging achieve a set state of charge of the battery by a set time.

  • Vehicle speed estimation system
    Patent number: 11230294
    Abstract: Disclosed is a system for estimating the speed of a vehicle. The system includes a plurality of wheel rotation sensors, a grade sensor, an acceleration sensor, an accelerator pedal deflection sensor, a brake pedal deflection sensor, and a processor. The processor is configured to compute a linear wheel speed, an upper limit of vehicle speed, and a lower limit of vehicle speed, based on the grade information, the pedal deflection information, and the acceleration, and then compute an estimated speed of the vehicle based on the linear wheel speed, the upper limit of vehicle speed, and the lower limit of vehicle speed.
