Patent number: 11041430Abstract: Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on echo times of an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. Engine power is limited differently based on distinct coolant level states determined based on a change in level of coolant in the reservoir over a duration.Type: GrantFiled: March 20, 2020Date of Patent: June 22, 2021Assignee: Ford Global Technologies, LLCInventors: John Eric Rollinger, Karen Willard, Michael Joseph Giunta, Robert Andrew Wade, Samer Ibrahim, Casey Dietrich, Matt Gerow

Patent number: 10513967Abstract: Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on echo times of an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. Sensor output is compensated with a term based on vehicle motion parameters to compensate for fluid level distortion due to motion-induced slosh.Type: GrantFiled: December 26, 2014Date of Patent: December 24, 2019Assignee: Ford Global Technologies, LLCInventors: John Eric Rollinger, Chad Everette Griffin, Casey Dietrich, Robert Roy Jentz, Alan Huang, Matt Gerow

Patent number: 10365146Abstract: Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on output from an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. The sensor uses a combination of raw echo times and processed fluid level data to estimate the fluid level accurately and reliably.Type: GrantFiled: December 26, 2014Date of Patent: July 30, 2019Assignee: Ford Global Technologies, LLCInventors: John Eric Rollinger, Robert Roy Jentz, William Russell Goodwin, Chad Everette Griffin, Casey Dietrich, Matt Gerow, Scott Steadmon Thompson
