Patent number: 9085287Abstract: A method for reducing the braking distance for a vehicle having an anti-lock braking mechanism (ABS) and a hydraulic braking system detects a brake pressure requested by the vehicle's driver (Prequested), and calculates the brakes pressure values at which the wheels of the vehicle lock. A maximum brake pressure value of these different brake pressure values is then compared with the driver's requested brake pressure value (Prequested). If the requested brake pressure value is much higher than the maximum brake pressure value, then the actual brake pressure applied at different wheels (Pactual) is set to a level below the requested brake pressure (Prequested), but still higher than the maximum brake pressure value. This reduces the amount of work required to be done by the ABS in pumping the excessive brake fluid out of the braking system of the vehicle, and allows for precise control of ABS mechanism during wheel slip conditions.Type: GrantFiled: August 11, 2012Date of Patent: July 21, 2015Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Ian Moore, Thomas Svensson, Rudolf Daniels

Publication number: 20150197226Abstract: A brake system for a motor vehicle having front and rear axles, the brake system having front and rear axle braking mechanisms operated under pressure control devices for producing a respective brake pressure on the front and rear axles of the motor vehicle. A controller receives signal information from sensors and systems on the motor vehicle to detect initiation of a braking process and detect a current speed of travel of the motor vehicle. An initial brake pressure for the rear axle braking mechanism is determined by the controller. A target brake pressure for the rear axle braking mechanism is determined by the controller and is representative of an increase in pressure relative to the initial brake pressure and the current speed of travel. Instructions from the controller operate the pressure control devices to produce the target brake pressure at the rear axle braking mechanism.Type: ApplicationFiled: January 9, 2015Publication date: July 16, 2015Inventor: Thomas Svensson

Patent number: 9020691Abstract: The present disclosure provides a hydraulic brake system for a motor vehicle and a method for the detection of a fault condition of the hydraulic brake system. An electronic control device determines at least one pressure value of the brake fluid of the brake system and at least one volume value of the brake master cylinder associated with the pressure value during an operation of a brake master cylinder. The electronic control device compares the determined pressure value and volume value with at least one pair of pressure-volume reference values for the detection of a fault condition of the brake system, wherein at least two different fault conditions of the brake system can be differentiated based on the comparison.Type: GrantFiled: April 17, 2014Date of Patent: April 28, 2015Assignee: Ford Global Technologies, LLCInventors: Thomas Svensson, Rudolf Daniels

Patent number: 9004615Abstract: A method for operating a hydraulic brake system of a motor vehicle, comprising a pressure generating device used to build up additional brake pressure in a master brake cylinder or in addition to a master brake cylinder and in opposition to further pedal actuation wherein the additional pressure is a function of the pedal actuation travel distance. A method that reduces the limitations of a braking system's physical parameters on the build-up of additional braking pressure.Type: GrantFiled: January 2, 2013Date of Patent: April 14, 2015Assignee: Ford Global Technologies, LLCInventors: Thomas Svensson, Ian Moore, Rudolf Daniels

Patent number: 8942907Abstract: A method for avoiding reducing scoring of the brake disc or the brake drum of a vehicle driven under rainy conditions calculates a product of three parameters, and activates an automatic braking operation for the vehicle, regularly, whenever the product exceeds the pre-determined threshold level. The first parameter is a rain intensity based parameter, a measure of the current raining intensity. The second parameter is a brake-activation-free driving time parameter, representing the time elapsed since the braking system of the vehicle was activated last. The third parameter is a speed parameter, which represents a current speed of the vehicle. As the automatic braking operation is carried out, the particles of dust, water, snow and de-icing substances, adhered to the brake disc of the vehicle, and causing scoring of the brake disc, are quickly removed, thus, reducing disc scoring.Type: GrantFiled: September 19, 2012Date of Patent: January 27, 2015Assignee: Ford Global Technologies, LLCInventors: Ian Moore, Thomas Svensson

Publication number: 20140277981Abstract: A method of operating a hydraulic brake system is described. A method of operating a hydraulic brake system of a motor vehicle having a mechatronic brake booster to boost a hydraulic pressure generated in a brake master cylinder of the brake system by a brake pedal of the motor vehicle determines whether a propulsion request is present during operation of the motor vehicle and actuates the mechatronic brake booster when a propulsion request has ended or been substantially reduced. During a predetermined time interval after the propulsion request has ended or been reduced, the mechatronic brake booster is operated at a minimum intensity such that no braking effect occurs during the predetermined time interval, unless a braking request occurs.Type: ApplicationFiled: March 18, 2014Publication date: September 18, 2014Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventor: Thomas SVENSSON

Patent number: 8788143Abstract: A method for testing a hydraulic braking system. The method includes activating a brake master cylinder of the braking system mechatronically, and measuring a set of measured decision ratios pertaining to the distance travelled by the piston of the brake master cylinder to the corresponding pressure developed in the brake fluid. The measured decision ratios are then compared with a set of reference decision ratios. In a case where the measured decision ratios lie within a predetermined range, it is detected that the braking system is correctly filled with the brake fluid. However, in a case where the measured decision ratios lie outside the predetermined range, it is determined that the braking system has not been correctly filled with the brake fluid and some air is present in the brake fluid flow circuit of the braking system.Type: GrantFiled: May 13, 2013Date of Patent: July 22, 2014Assignee: Ford Global Technologies, LLCInventors: Thomas Svensson, Rudolf Daniels, Ian Moore

Publication number: 20130297168Abstract: A method of operating a brake assistance system in a vehicle is disclosed. The method includes determining a braking operation as an emergency braking situation, which in turn includes sensing a braking pressure applied to a brake pedal, determining a braking pressure gradient of the braking pressure, and evaluating at least one factor of the driving situation, checking whether that factor indicates an emergency braking situation. If that factor indicates an emergency braking situation, adjustments to a braking pressure threshold value and a braking pressure gradient threshold value are carried out, reducing those threshold values by a predetermined amount. Thereafter, if both the braking pressure and the braking pressure gradient exceed the adjusted braking pressure threshold value and the adjusted braking pressure gradient threshold value, respectively, the braking operation is identified to be an emergency braking situation, accompanying activation of an emergency braking cycle.Type: ApplicationFiled: May 1, 2013Publication date: November 7, 2013Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventor: THOMAS SVENSSON

Publication number: 20130124060Abstract: A hydraulic braking system for a vehicle incorporating a vehicle dynamics control system (VDCS) includes an electromechanically actuated brake master cylinder that hydraulic braking system detects a reduction in the brake pressure of the wheel brake device, caused due to intervention of the VDCS in the braking operation, and moves a piston of the brake master cylinder in a direction opposite to an actuating direction. This causes an additional flow of the brake fluid from a reservoir to one or more pressure chambers of the brake master cylinder, thus, avoiding the piston from reaching a stop condition, and hence, avoiding an inadequacy in the volume of the brake fluid available in the pressure chambers of the brake master cylinder.Type: ApplicationFiled: October 19, 2012Publication date: May 16, 2013Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Thomas SVENSSON, Ian MOORE
