Publication number: 20050033499Abstract: The invention relates to a method for estimating road-to-tire friction between tires of a wheeled vehicle and a road surface, which vehicle is provided with a collision avoidance system. The method includes the steps of applying a positive torque to both wheels on a first axle and an equal and opposite negative torque to at least one wheel on a second axle. The method further includes measuring current values for vehicle speed, angular acceleration of the wheel on the second axle and the negative torque applied to said wheel. The method also includes determining a current friction coefficient using a friction coefficient determining device. The invention further relates to an apparatus for using the method.Type: ApplicationFiled: May 27, 2004Publication date: February 10, 2005Inventors: Jonas Ekmark, Jonas Jansson

Patent number: 6816764Abstract: A vehicle control system (10) including a vehicle motion control subsystem (12) that has an input receiving an intended driving demand (14) and a plurality of coordinator subsystems (16) for coordinating actuators of the vehicle. The vehicle motion control subsystem (12) communicates with the coordinator subsystems (16) to determine whether a single coordinator subsystem (16) can carry out the intended driving demand (14). The vehicle motion control subsystem (12) will distribute demand signals among one or more of the coordinator subsystems (16) to allow the vehicle to implement the intended driving demand (14).Type: GrantFiled: May 2, 2002Date of Patent: November 9, 2004Assignee: Ford Global Technologies, LLCInventors: Erik Coelingh, Jonas Ekmark

Publication number: 20040148080Abstract: A steering system and control system for controlling an assist force imposed to the steering assembly of a vehicle, so as to deliver a steering wheel resist torque that can be felt by the vehicle driver and a method for the same, wherein the actual steering wheel resist torque is compared with a desired steering wheel resist torque, whereupon the actual steering wheel resist torque is adapted to be substantially the same as the desired steering wheel resist torque through adapting the amount of said assist force.Type: ApplicationFiled: December 19, 2003Publication date: July 29, 2004Inventors: Jonas Ekmark, Erik Coelingh, Jochen Pohl

Patent number: 6659572Abstract: An emergency brake assist apparatus amplifies driver braking force upon imminent contact detection. A brake pedal, operated by the driver, exerts a pedal force upon a variable brake booster. A braking system is coupled to the variable brake booster that produces a variable brake booster force causing the braking system to exert a braking force proportional to the pedal force during normal operation. When a forward detection apparatus detects an imminent contact, a controller signals the variable brake booster to increase the variable brake booster force such that the braking system exerts an amplified braking force proportional to the pedal force.Type: GrantFiled: November 8, 2001Date of Patent: December 9, 2003Assignee: Ford Global Technologies, LLCInventors: John Vincent Bond, III, Gerald H. Engelman, M. Nabeel Tarabishy, Levasseur Tellis, Jonas Ekmark, Jonas Lars Zakarias Jansson

Patent number: 6655749Abstract: An enhanced emergency brake assist system includes an accelerator pedal operated by the driver coupled to a braking system and used to control the overall vehicle speed. When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle after the driver fully releases the accelerator pedal. The braking force may be reduced when the driver or passenger are unbuckled.Type: GrantFiled: November 8, 2001Date of Patent: December 2, 2003Assignee: Ford Global Technologies, LLCInventors: John Vincent Bond, III, Gerald H Engelman, Jonas Ekmark, Jonas L.

Patent number: 6607255Abstract: A brake control system (10) for an automotive vehicle (12) is provided. The system (10) includes a vehicle sensor complex (16) that generates a vehicle sensor complex signal and an object detection system (14) that generates an object detection signal. A brake controller (22) is electrically coupled to the vehicle sensor complex and the object detection system. The controller (22) in response to the vehicle sensor complex signal and the object detection signal generates a brake ramping control signal. Controller (22) adjusts brake pressure in response to the brake ramping control signal. A method for performing the same is also provided.Type: GrantFiled: January 17, 2002Date of Patent: August 19, 2003Assignee: Ford Global Technologies, LLCInventors: John Vincent Bond, III, Gerald H Engelman, Jonas Ekmark, Jonas L.

Patent number: 6523912Abstract: An autonomous emergency braking system includes an accelerator pedal operated by the driver coupled to a braking system and used to control the overall vehicle speed. When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle while the vehicle engine speed is reduced. The amount of brake force applied is a continuous function of relative speed, relative distance, collision probability and target classification. The braking force may be reduced when the driver or passenger are unbuckled or may be disabled if the driver applies full throttle.Type: GrantFiled: November 8, 2001Date of Patent: February 25, 2003Assignee: Ford Global Technologies, Inc.Inventors: John Vincent Bond, III, Gerald H Engelman, Jonas Ekmark, Jonas L.

When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle while the vehicle engine speed is reduced. The amount of brake force applied is a continuous function of relative speed, relative distance, collision probability and target classification. The braking force may be reduced when the driver or passenger are unbuckled or may be disabled if the driver depresses the accelerator pedal by a predetermined amount. In addition, the amount of brake force applied by the driver is amplified to further enhance braking performance.Type: GrantFiled: November 8, 2001Date of Patent: February 11, 2003Assignee: Ford Global Technologies, Inc.Inventors: John Vincent Bond, III, Gerald H Engelman, Jonas Ekmark, Jonas L.
