International Classification:

B62D 504

US Classification:

701 42, 701 41, 701 36, 701 48, 180170, 180 62, 280 55

Abstract:

A control system for a steering system in a vehicle comprising: a reference model responsive to an operator input that computes desired states of the vehicle; a feedforward controller in operable communication with the reference model. The feedforward controller computes a first control value based on input from said reference model and based on at least one of: a lateral velocity, a rate of lateral velocity, a lateral acceleration, and a combination, wherein the combination includes a yaw rate with at least one of a lateral velocity, a rate of lateral velocity, and a lateral acceleration of the motor vehicle. The system also includes an actuator for affecting the steering system based on the first control value, the actuator in operable communication with the feedforward controller.

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B62D005/04

US Classification:

180422, 180446

Abstract:

Disclosed herein in an exemplary embodiment is a method for providing variable assist in an active steering system of a vehicle. The method comprises: receiving an input signal that includes at least one of, a variable ratio command signal, a stability command signal, a hand wheel position signal, a vehicle speed signal indicative of a speed of the vehicle, a signal indicative of an operator selected function, and a signal indicative a vehicle operating mode. The method also comprises: generating an assist command to an assist mechanism responsive to the input signal wherein the assist mechanism is operatively coupled to the differential actuator and a road wheel of the steering system to provide an assist torque responsive to the motion of the output shaft. The active steering system includes a hand wheel operatively coupled to an input of a differential actuator and a motor operatively coupled to the differential actuator. The differential actuator is configured to translate motion of the input into motion of the output shaft, where the motion of the output shaft is further responsive to the motor and wherein the output shaft is coupled to the road wheel of the steering system.

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B62D005/04

US Classification:

180446, 701 42, 318432

Abstract:

A method and apparatus for controlling the feel back torque of a motor provides for receiving a difference between a desired motor position and an actual motor position; filtering the difference into two or more frequency bands; and applying a gain to one or more of the filtered frequency bands in correspondence with the received signal or a low-pass portion of the received signal to provide a motor command.

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B62D 7/09

US Classification:

180411, 180410, 701 41

Abstract:

A method for implementing anti-static steering for vehicle steering systems includes receiving a desired rear wheel angle input and receiving a vehicle speed input. An approved rear wheel angle output is generated using the desired rear wheel angle input and the vehicle speed input, wherein the approved rear wheel angle is based upon one of a plurality of defined operating states, the plurality of operating states including operation at a speed in a first range, operation at a speed in a second range, and transitions therebetween.

Appl. No.:

10/236208

Inventors:

John Martens - Dellwood MN, US
John Shudy - Minneapolis MN, US

International Classification:

G06F015/16

US Classification:

709/227000, 709/245000

Abstract:

A process links computers through a service. A user mechanically reads coded information, such as information from a bar code. Each bar code provides information unique to a service subscriber with fewer than or equal to 36 characters being read. The equal to or fewer than 36 characters can activate a distal address to access information relating to that specific subscriber, the service connecting the user to that address; and provide a compilation of information on the subscriber to the user upon execution of software reading the fewer than or equal to 36 characters.
