Filed:

Aug 29, 2008

Appl. No.:

12/202162

Inventors:

Assignee:

PACCAR INC - Bellevue WA

International Classification:

B60Q 1/00

US Classification:

340461

Abstract:

Information display systems capable of iconically representing the components of a hybrid powertrain and method thereof. In operation, the information display systems indicate the specific powertrain components in the hybrid system that are active in various hybrid operational modes (e.g., electric launch, blended torque, etc.). In particular, active components are highlighted (i.e., increased intensity) by the display and non-active components are faded (i.e., decreased intensity). In one embodiment, the vehicle wheels are depicted with a static intensity in-between that of the active components and the non-active components. This allows the vehicle operator to clearly see which components are active during each hybrid system mode, and to gain a simplified picture of hybrid system behavior during normal operation at a glance.

International Classification:

G06F 19/00

US Classification:

701 22, 701 29, 903903

Abstract:

An information display system is provided that presents the configuration of a vehicle's axles along with one or more other powertrain components in iconic format to the vehicle operator. The information display system may also present information that allows the driver to increase fuel efficiency.

US Classification:

701 22, 701123, 903903

Abstract:

Information display systems present information that allows the driver to increase fuel efficiency of a vehicle, such as a hybrid vehicle. In one example, the systems present information in a manner that allows the driver to maximize the time that the hybrid vehicle is able to operate in electric launch mode. One manner is employing a graphical display that generates visual indicators and easily understood graphical representations that display the actual fuel efficiency currently being achieved in comparison to the driver's application of the throttle. As a result, the driver may be able to modify driving habits in order to keep the hybrid vehicle in electric launch mode for as long as possible.The information display system may also display additional information to the vehicle operator, allowing the vehicle operator to clearly see both textually and iconically which mode of operation the hybrid vehicle is currently operating so that operator behavior can be modified for increasing fuel efficiency of the vehicle.
