Patent number: 9824505Abstract: Methods and systems are provided for improving the frequency of attempting and successfully completing one or more on-board diagnostic routines. Engine operating conditions are predicted based on a vehicle operator's driving pattern and routines are initiated if the predicted conditions match the conditions required for performing the routine. If the conditions do not match, entry and/or execution conditions of the routine are adjusted to better match the predicted conditions, so as to enable the routine to be attempted.Type: GrantFiled: February 25, 2014Date of Patent: November 21, 2017Assignee: Ford Global Technologies, LLCInventors: Fling Tseng, Imad Hassan Makki, Robert Roy Jentz, Aed M.

Publication number: 20170330395Abstract: A controller includes a processor programmed to determine, for a vehicle, a first control input based on input data and first reference parameters. The processor is further programmed to operate the vehicle according to the first control input. Based on operating data of the vehicle for an operating condition, the processor determines a second control input for the vehicle. Operating the vehicle according to the second control input reduces a cost of operating the vehicle relative to operating the vehicle according to the first control input. The processor is further programmed to determine, based on the second control input, second reference parameters. The controller generates a third control input based on the second reference parameters and the input data. A cost of operating the vehicle according to the third control input is reduced relative to the cost of operating the vehicle based on the first control input.Type: ApplicationFiled: May 13, 2016Publication date: November 16, 2017Applicant: Ford Global Technologies, LLCInventors: Jing Wang, Yan Wang, Dimitar Petrov Filev, John Ottavio Michelini

Publication number: 20170253241Abstract: A system includes a computing device programmed to receive a set of goals for a vehicle and identify a travel area for the vehicle for a time period. The computing device receives data indicating predictability of driving conditions of the travel area and determines that the predictability is sufficient to control the vehicle according to model predictive control. Controlling the vehicle includes determining instructions to control actuators related to the steering, propulsion and braking of the vehicle to minimize a cost function. The instructions are implemented for a first time slot. The time period is updated to remove the first time slot at the beginning and include an additional time slot at the end of the predetermined time period. The computing device determines an updated control solution, and implements the updated control solution for a second time slot.Type: ApplicationFiled: March 1, 2016Publication date: September 7, 2017Applicant: Ford Global Technologies, LLCInventors: Dimitar Petrov Filev, Jianbo Lu, Davor D.

Publication number: 20170240167Abstract: A computer for, e.g., a mass market passenger vehicle operable by a virtual driver in autonomous and/or semi-autonomous mode, is programmed to determine that a current vehicle braking capacity exceeds each of a first braking target and a mitigation threshold at a current vehicle speed. The computer is further programmed to compare the current vehicle speed to an engine breaking threshold and generate a transmission control message providing data to operate a vehicle transmission. Where the current vehicle speed is above the engine braking threshold, the transmission control message provides data to operate the vehicle transmission to inhibit transfer of an input torque through the vehicle transmission. Additionally, where the current vehicle speed is below a wheel lock threshold, the transmission control message further provides data to operate the vehicle transmission to inhibit rotation of an output shaft of the vehicle transmission.Type: ApplicationFiled: February 18, 2016Publication date: August 24, 2017Applicant: Ford Global Technologies, LLCInventors: Jianbo Lu, Dimitar Petrov Filev
