Patent number: 11017300Abstract: A system that suggests and refines priority, severity, historical resolution, resolution time and assignment group to resolve auto-generated incidents is provided. The system leverages an incident characterization list tracking essence key phrases associated with historical incidents generated by an application performance management (APM) system and a machine data (MD) analysis system. The system automatically obtains a first auto-generated incident, from the APM system or the MD analysis system, based on any specified search criteria being met, or detection of a deviation in the value of key metrics from a specified threshold value.Type: GrantFiled: November 7, 2017Date of Patent: May 25, 2021Assignee: Digital.ai Software, Inc.Inventors: Rahul Kapoor, Srikanth Gopalaswami, Michael Fodor

Patent number: 8694223Abstract: A method of controlling a traction control system (30) includes continuously adapting a steady state driven wheel speed to reference wheel speed ratio, so that said traction control system can avoid unnecessary actuations (e.g., demanding torque reduction). The continuous adaptation methodology provides traction control robustness to vehicles equipped with a spare tire, or a different final drive such as in the use of aftermarket parts. The method includes a dual rate adaptation that allows both fast adaptation and fine tuning capabilities of the ratio. The method includes comparing the instant driven wheel speed to reference wheel speed ratio to the filtered driven wheel speed to reference wheel speed ratio, to obtain a ratio difference. When the difference is above a threshold, the first filter constant is selected and the first constant is applied to an adaptation filter, resulting in a first filtered and adapted ratio. The traction control system is controlled with the adapted ratio.Type: GrantFiled: February 19, 2009Date of Patent: April 8, 2014Assignee: Ford Global Technologies, LLCInventors: Hongtei Eric Tseng, Michael Fodor, Davor Hrovat

Patent number: 8108104Abstract: A rollover stability control system for a vehicle may include an object information device. An active suspension or an active steering system may be coupled to a wheel of the vehicle. The rollover system may include a lateral support system. A controller determines that an obstacle is an imminent tripping obstacle and raises or steers the wheel, to prevent the wheel from colliding with the obstacle, or deploys the lateral support system in response to a rollover notification signal and the determination. A rollover stability control system for a vehicle may include a chassis and a driving surface wheel. A wheel assembly is coupled to the chassis inward from the driving surface wheel relative to a longitudinal centerline of the vehicle. The wheel assembly contacts the driving surface when a roll angle of the vehicle is greater than a predetermined level.Type: GrantFiled: November 16, 2006Date of Patent: January 31, 2012Assignee: Ford Global Technologies, LLCInventors: Davor Hrovat, Eric Tseng, Michael Fodor

Patent number: 7873459Abstract: A method of controlling a vehicle that includes determining a dynamic normal load for the vehicle wheel, modifying the requested torque signal from a traction control system in response to the dynamic normal load to form a modified requested torque and controlling the engine in response to the modified requested torque. The controlling may be performed using the ratio of the dynamic normal load and the steady state normal load to form the modified requested torque.Type: GrantFiled: July 29, 2005Date of Patent: January 18, 2011Assignee: Ford Global Technologies, LLCInventors: Michael Fodor, Davor Hrovat

Patent number: 7499787Abstract: In one example, A method for controlling a powertrain of a vehicle with wheels, the vehicle having a pedal actuated by a driver, is described. The method may include generating powertrain torque transmitted to the wheels in a first relation to actuation of the pedal by the driver during a first condition where said transmitted torque causes said wheels to slip relative to a surface; overriding said driver actuated powertrain torque to control said slip; and during a second condition after said first condition where said vehicle is moving less than a threshold, generating powertrain torque transmitted to the wheels in a second relation to actuation of the pedal by the driver, where for a given pedal position, less powertrain torque is transmitted with said second relation compared to said first relation.Type: GrantFiled: October 7, 2004Date of Patent: March 3, 2009Assignee: Ford Global Technologies, LLCInventors: Davor Hrovat, Michael Fodor, Mitch McConnell
