Publication number: 20140046468Abstract: A tool is provided to allow a user to customize the components of a vehicle instrument panel from an Internet-enabled Web site. A user can navigate to a Web site and select a vehicle for configuration. From the Web site, input may be obtained regarding the components and appearance of an instrument panel such as selecting particular types of components (e.g., display panels, gauges, etc.) and arranging where the selected components are to be located. The input generated by a user is translated into a build specification for assembling the instrument panel at the manufacturer. Accordingly, the system and method serve as an interface between the Web site that obtains user configuration data and a manufacturer's system that manages assembly of the vehicle.Type: ApplicationFiled: October 15, 2013Publication date: February 13, 2014Applicant: PACCAR INCInventors: Christopher Tarte, Paul Stephen Crowe

Patent number: 8049605Abstract: Aspects of the present invention are directed at allowing a vehicle to idle for a predetermined amount of time before shutdown. In accordance with one embodiment, a method is provided that accepts input from the vehicle operator to initiate a countdown to vehicle shutdown. When the input is received, a countdown is initiated that is regularly updated to reflect the passage of time. During the countdown, a vehicle ignition bus is maintained in an active state and a countdown value that reflects the time remaining before shutdown is presented on a graphical display. Then, in response to expiration of the countdown, the method allows the vehicle ignition bus to transition into an inactive state.Type: GrantFiled: January 21, 2011Date of Patent: November 1, 2011Assignee: PACCAR IncInventors: Martin Jay Caspe-Detzer, Andrew Joseph Ressa, Phu Vi Tran, Ian David O'Connor, John William Espinosa, Paul Stephen Crowe
