Publication number: 20240013589Abstract: A controller for a vehicle includes at least one processor and at least one memory storing instructions that, when executed by the processor, cause the controller to perform various operations. The operations include determining that a power loss to the controller has occurred. In response to the determination that the power loss has occurred, the operations are structured to determine whether a key switch associated with an engine of the vehicle is on; and, when the key switch is on, save operating data to a ferroelectric random access memory (TRAM) coupled to the controller.Type: ApplicationFiled: July 7, 2021Publication date: January 11, 2024Applicant: Cummins Inc.Inventors: Vratika Malavia, Amar Deshmukh, Abhik Giri

Patent number: 11668260Abstract: Methods and apparatuses for connecting multiple loads with a common return pin in engine control module application are disclosed. Only one of the multiple loads can be connected to a power source at a time. At the high side, each load is coupled to the power source through a respective pin at a connector. At the low side, the multiple loads share a common return pin at the connector that connects the loads to the ground. When a first load is connected to the power source at the high side, a first low side driver circuit is used to connect the first load to the ground at the low side. When a second load is connected to the power source at the high side, the second low side driver circuit is used to connect the second load to the ground at the low side.Type: GrantFiled: November 8, 2021Date of Patent: June 6, 2023Assignee: Cummins Inc.Inventors: Abhik Giri, Ashish Raj Jain, Ming Feng, Mark Swain

Publication number: 20220320892Abstract: A controller includes a microcontroller and a control circuit. The control circuit includes circuitry structured to sense an alternating current (AC) from a current transformer coupled to the controller, convert the AC to direct current (rectified output DC), charge a capacitor to a first predetermined voltage level using the rectified output DC of the current transformer, and switch from a primary power supply for the microcontroller to a secondary power supply that includes the capacitor. The control circuit includes circuitry structured to cause the capacitor of the secondary power supply to provide power, at a second voltage level, to a clock coupled to the microcontroller.Type: ApplicationFiled: July 30, 2019Publication date: October 6, 2022Inventors: Shekhar Ganesh Sahasrabudhe, Dhairyashil Hemantkumar Patil, Abhik Giri

Patent number: 11175690Abstract: Systems and apparatuses include a control circuit and a switching circuit. The control circuit is structured to communicate with a real-time-clock battery and to selectively communicate with a vehicle battery. The control circuit is structured in an OFF arrangement when a wake supply voltage is received from the vehicle battery and in an ON arrangement when no wake supply voltage is received. The switching circuit is structured to provide communication between the real-time-clock battery and a real-time-clock power pin of a controller with a voltage drop of about 0.1 volts or less when the control circuit is in the ON arrangement and to inhibit communication between the real-time-clock battery and the real-time-clock power pin when the control circuit is in the OFF arrangement.Type: GrantFiled: April 9, 2020Date of Patent: November 16, 2021Assignee: Cummins Inc.Inventors: Abhik Giri, Mark Swain, Ashish Raj Jain, Ming Feng, Astha Ganjoo, Shreya Ghatge
