An integrated message system for a vehicle provides an extendable, prioritized message scheme. Using this scheme, the message system acts as a centralized message provider for variety of alerts and operating data originating throughout the vehicle. The message system defines a hierarchy of message levels, each having a unique output protocol. The protocol defines attributes associated with messages at a particular level such as textual or graphical message, an auditory alert, as well as the scheme for playing these messages and alerts. The system integrates a variety of subsystems that conventionally have separate driver interfaces such as a collision warning system and an adaptive cruise control system.

A fuel efficiency monitoring and display system for a vehicle dynamically evaluates vehicle performance parameters to detect conditions that cause excessive fuel consumption. The conditions include increased aerodynamic drag due to excessive speed, high RPM, braking and accelerating, excessive idling, and rapid throttle movements. The system dynamically estimates gross vehicle weight, roadway grade and drag factor from monitored parameters and uses these estimates to detect inefficient fuel use. The system indicates to the driver when inefficient fuel use is detected. For example, it displays a measure of excess fuel consumed and messages indicating actions that can be taken to improve fuel economy in response to detecting inefficient fuel use.
