Publication number: 20240051523Abstract: A computer includes a processor and a memory, the memory storing instructions executable by the processor to receive sensor data indicating an obstacle, formulate a control barrier function for a vehicle based on the sensor data, determine a control input based on the control barrier function, and actuate a component of the vehicle according to the control input. The control barrier function is defined with respect to a reference point that is spaced from a centroid of the vehicle.Type: ApplicationFiled: August 10, 2022Publication date: February 15, 2024Applicant: Ford Global Technologies, LLCInventors: Mohit Srinivasan, Hongtei Eric Tseng, Michael Hafner, Mrdjan J. Jankovic, Abhishek Sharma, Erol Dogan Sumer, Alexander Jaeckel, Aakar Mehra

Publication number: 20230399002Abstract: A system includes a processor and a memory. The memory stores instructions executable by the processor to determine a virtual barrier around a vehicle based on receiving a first user input and data indicating a vehicle sprung mass, upon receiving a second user input selecting the virtual barrier, to determine an updated virtual barrier based on the received second user input, upon determining the virtual barrier, to verify that the virtual barrier satisfies one or more vehicle parameters; and to provide output based on the virtual barrier.Type: ApplicationFiled: June 14, 2022Publication date: December 14, 2023Applicant: Ford Global Technologies, LLCInventors: Erol Dogan Sumer, Abhishek Sharma, Mohit Srinivasan, Alexander Jaeckel, Michael Hafner, Mrdjan J.

Publication number: 20230373471Abstract: A computer includes a processor and a memory, and the memory stores instructions executable by the processor to receive sensor data indicating an obstacle, formulate a control barrier function for a vehicle and the obstacle based on the sensor data, determine a control input based on the control barrier function and a combination function, and actuate a component of the vehicle according to the control input. The combination function is a sum of a first function weighted by a first weight and a second function weighted by a second weight, and the first weight and the second weight are based on a kinematic state of the obstacle.Type: ApplicationFiled: May 17, 2022Publication date: November 23, 2023Applicant: Ford Global Technologies, LLCInventors: Abhishek Sharma, Michael Hafner, Mohit Srinivasan, Mrdjan J.

Patent number: 10495522Abstract: Methods and systems are provided for estimating engine oil temperature during conditions when sensors used for engine oil temperature measurement are not functional or not reliable. A null duty cycle of a solenoid spool valve of a variable cam timing mechanism is estimated. Then, a calibrated relationship between the duty cycle, an angular velocity of the associated cam, and the engine oil temperature is used to estimate an engine oil temperature when existing sensors used in the calculation of engine oil temperature calculation become unreliable.Type: GrantFiled: September 29, 2017Date of Patent: December 3, 2019Assignee: Ford Global Technologies, LLCInventors: Erol Dogan Sumer, Yan Wang
