Patent number: 10899383Abstract: The disclosure concerns a tilting vehicle with at least one multi-wheel axle, a vehicle structure and a control unit that is arranged to detect a lateral acceleration acting on the tilting vehicle and actively adjust a tilt angle of the structure of the vehicle about the longitudinal axis thereof. In order to optimize adjustment of the tilt angle in a tilting vehicle, the control unit is arranged to adjust the tilt angle so that in a direction of a lateral axis of the structure of the vehicle, a Y component of the lateral acceleration is partially compensated by a Y component of acceleration due to gravity according to a specified compensation proportion. The compensation proportion increases as a function of the lateral acceleration to a global maximum value at a first acceleration, and decreases above the first acceleration.Type: GrantFiled: July 12, 2018Date of Patent: January 26, 2021Assignee: Ford Global Technologies, LLCInventors: Marc Simon, Lucian Lippok

Patent number: 10703376Abstract: A method is described for controlling the automatic starting of a motor vehicle comprising an electronically controllable locking differential, uphill in a split mu situation. The method comprises the following steps: determining the positive gradient of the underlying surface; defining an initial locking torque on the basis of the determined positive gradient and on the basis of a component of the torque which the vehicle requires to travel uphill with only the first driven wheel powered; calculating the slip ratio SRxx for the first driven wheel xx according to SRxx=(Vxx?VRef)/VCrit if the reference velocity VRef is between 0 and a critical velocity VCrit, and according to SRxx=(Vxx?VRef)/VRef if the reference velocity VRef is higher than the critical velocity VCrit; and defining the locking torque of the electronically controllable locking differential on the basis of the slip ratio of the first driven wheel.Type: GrantFiled: July 2, 2018Date of Patent: July 7, 2020Assignee: Ford Global Technologies, LLCInventors: Cyril Coerman, Lucian Lippok, Robert Barend Ter Waarbeek, Georg Johann Maurer

Patent number: 10532656Abstract: The invention concerns a method for operating a motor vehicle with selectable all-wheel drive. The all-wheel drive is implemented with no central differential and the rear axle is implemented with no axle differential. The motor vehicle includes first and second partial clutches for independently decoupling left and right rear wheels from the drive train of the motor vehicle motor vehicle. The method includes determining a value that is representative of a ratio of the speeds of the front wheels to each other, comparing the value with a reference value, and disengaging the partial clutch that is associated with an outer rear wheel when the motor vehicle is turning, when the value is greater than the reference value, in order to prevent negative torques on the outer rear wheel.Type: GrantFiled: December 1, 2017Date of Patent: January 14, 2020Assignee: Ford Global Technologies, LLCInventors: Cyril Coerman, Lucian Lippok

One embodiment of the invention relates to a method for estimating the negative pressure in a motor vehicle brake force booster with reference to the hydraulic pressure in a brake master cylinder. According to the embodiment, the negative pressure is estimated solely on the basis of hydraulic pressure in the brake master cylinder and of the actual engine speed. One embodiment of the invention also relates to a stop/start control device for a motor vehicles.Type: GrantFiled: June 29, 2010Date of Patent: March 24, 2015Assignee: Ford Global Technologies, LLCInventor: Lucian Lippok

Publication number: 20140324290Abstract: A method for controlling cornering of a motor vehicle having a front wheel drive and an electronically controllable locking differential. A motion model of the motor vehicle is calculated on the basis of the control inputs of a vehicle driver, a lateral movement parameter of the motor vehicle is measured. Deviations of the measured lateral movement parameter to the modeled movement, and the rotational speed of a front wheel which is on the inside during cornering from such a rotational speed of a front wheel which is on the outside are determined. The deviations are reduced if the rotational speed of the front wheel which is on the inside is not lower than the rotational speed of the front wheel which is on the outside, and if the measured lateral movement parameter deviates from the modeled lateral movement parameter. Reduction of the deviation is carried out by applying a locking torque to the locking differential and by single-sided braking of at least one wheel.Type: ApplicationFiled: April 30, 2013Publication date: October 30, 2014Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Jens Dornhege, Derek K.
