Patent number: 11772664Abstract: A system includes a processor and a memory. The memory stores instructions executable by the processor to determine an action for a vehicle based on an identified risk condition, to determine a minimum time for performing the action, and based on data including a vehicle battery state of charge, an outdoor temperature, and a vehicle mode of operation, to determine an available electrical power for performing the action. The instructions further include instructions to determine maximum permissible electrical energy discharge rate based on the minimum time for performing the action and the determined available electrical power, to determine a load control plan for a plurality of electrical devices in the vehicle based on the maximum permissible electrical energy discharge rate, an electrical load status of the vehicle, and load priority data; and to execute the determined load control plan.Type: GrantFiled: June 26, 2020Date of Patent: October 3, 2023Assignee: Ford Global Technologies, LLCInventors: David A. Symanow, Ray C. Siciak, Dhanunjay Vejalla

Patent number: 11715338Abstract: A plurality of fault conditions are detected on a communication network onboard a vehicle. The detected fault conditions, a fault condition importance, environment conditions, and a vehicle operation mode are input to a neural network that outputs rankings for respective detected fault conditions. The neural network is trained by determining a loss function based on a maximum likelihood principle that determines a probability distribution that ranks the detected fault conditions. The vehicle is operated based on the rankings of the fault conditions.Type: GrantFiled: January 12, 2021Date of Patent: August 1, 2023Assignee: Ford Global Technologies, LLCInventors: Dhanunjay Vejalla, David A. Symanow, Ray Siciak

Patent number: 9362854Abstract: A motor system and a method of operating an electric motor that includes monitoring a voltage of power supplied to the motor by a mircrocontroller located in the motor; storing energy within the motor; detecting if the voltage drops below a nonzero threshold; and if the voltage drops below the threshold, immediately operating the microcontroller with the stored energy to store a state of the motor in non-volatile memory located within the motor, and ceasing operation of the motor. This motor operation may be employed with multiple motors in vehicles where voltage drop may occur during an engine start of a vehicle stop/start event.Type: GrantFiled: December 12, 2013Date of Patent: June 7, 2016Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: David A.
