Patent number: 11945456Abstract: Upon detecting a mobile object approaching a target region, a target speed profile for a vehicle, a position and a speed for the vehicle, and a position and a speed for the mobile object are input to a first neural network that outputs an entry probability distribution of predicted entry times at which the mobile object will enter the target region. The target speed profile, the position and the speed for the vehicle, the position and the speed for the mobile object, and a predicted entry time at which the mobile object entered the target region are input to a second neural network that outputs an exit probability distribution of predicted exit times at which the mobile object will exit the target region. An optimized speed profile is determined based on the entry and exit probability distributions by executing a model predictive control algorithm in a rolling horizon. A vehicle is operated based on the optimized speed profile.Type: GrantFiled: January 31, 2022Date of Patent: April 2, 2024Assignee: Ford Global Technologies, LLCInventors: Branimir Skugor, Jakov Topic, Josko Deur, Vladimir Ivanovic, Hongtei Eric Tseng

Patent number: 11414081Abstract: A powertrain includes a transmission having an input shaft, an output shaft, and a plurality of clutches engageable in various combinations to establish varying power flow paths between the input and output shafts. A controller is programmed to, responsive to a shift of the transmission: reduce torque capacity of an off-going one of the clutches and increase torque capacity of an oncoming one of the clutches during a torque transfer phase of the shift, and, in response to an inertia phase of the shift, continue to command non-zero torque capacity to the off-going clutch such that the off-going clutch brakes the output shaft throughout an entire duration of the inertia phase.Type: GrantFiled: February 4, 2021Date of Patent: August 16, 2022Assignee: Ford Global Technologies, LLCInventors: Ivan Cvok, Josko Deur, Vladimir Ivanovic, Yijing Zhang, Yuji Fujii

Patent number: 7451034Abstract: A method for controlling slip of a driven wheel on low friction surfaces includes determining the current magnitude of static tire friction potential, current magnitude of maximum dynamic tire friction potential, and magnitude of tire torque demanded by an operator of the vehicle. A lower magnitude of commanded tire force is set less than the estimated current magnitude of static tire friction potential. The magnitude of demanded wheel torque and the estimated current magnitude of maximum dynamic tire friction potential are used to set an upper magnitude of commanded tire force. The magnitude of commanded tire force is changed in a sequence of saw-tooth pulses, each pulse including an increasing ramp of tire force from the lower commanded tire force to the upper commanded tire force, the ramp having a predetermined slope, and a step that reduces the magnitude of commanded tire force between each pulse to the lower commanded tire force.Type: GrantFiled: March 10, 2006Date of Patent: November 11, 2008Assignee: Ford Global Technologies, LLCInventors: Josko Deur, Jahan Asgari, Davor Hrovat

Patent number: 6651761Abstract: A system and method to control the coolant temperature of two independent cooling loops of a fuel cell vehicle by adjusting system pump speed, fan speed and radiator bypass valve position. Multiple feedback controllers coordinated by robust flip-flop logic are used, to minimize energy consumption and provide optimal control system performance even in the case of substantially different plant responses with respect to fan speed and valve position plant inputs. The system also includes a feed forward disturbance compensator, which reacts immediately to change in net power and vehicle speed disturbance variables, thereby reducing the variance of the temperature control error. Additionally, a feedback controller preset strategy is used to compensate for distinctive plant nonlinear effects such as bypass valve dead-zone and air-conditioning system's request for abrupt change of fan speed.Type: GrantFiled: April 18, 2002Date of Patent: November 25, 2003Assignee: Ford Global Technologies, LLCInventors: Davorin David Hrovat, Jahanbakhsh Asgari, Josko Deur, William Samuel Schwartz
