US Patent:

6600985, Jul 29, 2003

Filed:

May 13, 2002

Appl. No.:

10/144327

Inventors:

Ralph M. Weaver - Fishers IN
Michael L. Miller - Carmel IN

Assignee:

Indiana Mills Manufacturing, Inc. - Westfield IN

International Classification:

B60R 2200

US Classification:

701 45, 180282, 280735, 340440, 340438

Abstract:

A roll sensor system for a land vehicle is provided to determine when a vehicle roll condition has occurred and to trigger a safety system in response to that determination. In certain embodiments, an angular rate sensor is used to obtain an angular rate and, from the angular rate, an angle relative to the roll axis of the land vehicle. If the angular rate and the angle correspond to a safety system activation event, the roll sensor system will provide a trigger signal to the safety system. In some embodiments, the system includes an incline sensor(s) to aid in detecting and compensating for drift in the output of the angular rate sensor. In other embodiments the output of an angular rate sensor is used to validate the output of the incline sensor to aid in determining whether a vehicle safety system trigger event has occurred.

Abstract:

A method and apparatus for generating calibration information in which a subfile type is defined for each of a plurality of categories of data including (1) engine control data, (2) engine family data, (3) vehicle interface data, (4) software sequencing data, (5) electronic configuration data, and (6) memory configuration data. A separate subfile is created in memory for each of a plurality of individual sets of data in each of the data categories. Each subfile is automatically provided with line checksums, a cyclic redundancy code, date information, a subfile type identifier, and a subfile authorization level, and data entries are automatically verified base on rules stored in memory in a rules file, each of the subfile types having an associated rules file, and each of the rules files defining criteria for individual data items and for interrelationships between data items in its associated subfile type. A compatibility file is created in memory to identify subfiles of one type which are compatible with a subfile of another type. Each subfile and the compatibility file are distributed individually via an electronic communication link to multiple service computers programmed to determine compatibility among selected subfiles based on information stored in the compatibility file and to assemble compatible subfiles into a calibration file for a particular engine control module.
