Patent number: 10315630Abstract: A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.Type: GrantFiled: May 2, 2017Date of Patent: June 11, 2019Assignee: Ford Global Technologies, LLCInventor: Thomas Svensson

Publication number: 20190124382Abstract: A MoCA network management device is configured to enable data communication between client devices that are connected to different MoCA end devices in a MoCA Access network, by providing a redirection function for the MoCA end devices that are configured to be included in a VLAN within the MoCA Access network. The VLAN may include MoCA end devices in different rooms of a building. The MoCA network management device, which is installed intermediate the MoCA end devices and an external data channel, is configured to receive outgoing data generated by client devices that are connected to the MoCA end devices, access a database containing identifiers that are associated with the MoCA end devices in the VLAN, and selectively, based on the database, redirect the outgoing data to a selected MoCA end device among the MoCA end devices in the VLAN.Type: ApplicationFiled: November 27, 2017Publication date: April 25, 2019Inventor: Thomas Svensson

Patent number: 10259439Abstract: A method for controlling an electric parking brake for a motor vehicle including a brake actuator having an electric motor disposed directly on the brake caliper. When the parking brake is utilized as an additional service brake, depending on a brake pedal brake command, the electric motor is initially energized on detection of an imminent or commencing brake-pedal actuation however the electric motor generates no braking force until a predetermined or specific brake command is received. As a result, an overload of the vehicle voltage source is avoided if simultaneous utilization of multiple parking-brake actuators occurs.Type: GrantFiled: July 31, 2016Date of Patent: April 16, 2019Assignee: Ford Global Technologies, LLCInventors: Marc Suermann, Jill Trappe, Rudolf Daniels, Thomas Svensson

Patent number: 10239510Abstract: A method of controlling a brake system of a motor vehicle having a braking assistance function. The brake system including a master brake cylinder, activated with a brake pedal. A distance s between a valve piston connected to the brake pedal, and a transmission element, connected to a pressure piston of the master brake cylinder is sensed and the brake system is controlled as a function of the sensed distance s. Within the scope of this monitoring process, brake pedal release is detected even when the pressure-generating unit is activated. In addition, despite an active braking assistance function, consistent interplay occurs between activation by the driver and assistance-side activation of the brakes given satisfactory pedal feedback.Type: GrantFiled: January 7, 2016Date of Patent: March 26, 2019Assignee: Ford Global Technologies, LLCInventor: Thomas Svensson

Patent number: 10196062Abstract: A method for stopping of a motor vehicle including providing a creep torque via a drive train of the motor vehicle and then increasing, independently of the driver, engine speed of a drive engine of the drive train to increase a drive torque of the drive engine and simultaneously increasing, independently of the driver, a braking torque of a brake system of the motor vehicle to balance the drive torque and the braking torque of the motor wherein the maximum braking torque is as great as the creep torque during a standstill of the motor vehicle. The method then maintains the braking torque and simultaneously reduces the engine speed of the drive engine to point at which the motor vehicle comes to a standstill.Type: GrantFiled: April 14, 2017Date of Patent: February 5, 2019Assignee: Ford Global Technologies, LLCInventors: Ashrit Das, Thomas Svensson

Patent number: 10124775Abstract: The disclosure relates to a method for operating a motor vehicle which is capable of driving either under the control of a human driver who is located on board the motor vehicle or autonomously, at least over certain sections of a route, and which is able to avoid collisions, detect adverse effects on the driver and bring about emergency stops. Accordingly, the motor vehicle has an emergency braking assistant, and if an adverse effect on the driver is detected in the autonomous driving mode, a characteristic curve which is preset for emergency braking operations is changed in such a way that an emergency braking operation is initiated at an earlier point and the braking force is built up more slowly than in the non-autonomous driving mode.Type: GrantFiled: May 20, 2016Date of Patent: November 13, 2018Assignee: Ford Global Technologies, LLCInventors: Thomas Svensson, Timothy Jurkiw

Patent number: 9944265Abstract: A method for controlling a brake pressure booster with hydraulic brake boosting wherein the activation of an additional pressure source takes place upon exceeding a specified brake cylinder pressure threshold value. The threshold value lying between 50% and 100%, preferably between 70% and 80%, of a pressure limit value, from which the operating travel/brake pressure curve without additional brake pressure assistance has a knee point. Further upon exceeding a specified piston rod activation travel limit value, which lies at 20% to 100% of the available travel, preferably at 40% to 60% of the available travel. Furthermore, the speed of the vehicle, its lateral deceleration and its longitudinal deceleration can be used as criteria. Deactivation takes place on falling below a specified piston rod deactivation travel limit value. Based on selection of activation/deactivation criteria additional brake pressure boosting can be operational during braking maneuvers.Type: GrantFiled: July 15, 2014Date of Patent: April 17, 2018Assignee: Ford Global Technologies, LLCInventors: Thomas Svensson, Thomas Eichhorn
