The vehicle speed, engine operating speed and manifold pressure (46) of the vehicle are compared to corresponding preset threshold values. The total time (34, 38, 30) during which each of the vehicle speed, engine operating speed and manifold pressure exceed its threshold value is recorded and provided to the driver in a real-time display (18). The total time (42) during which the engine is idling are also recorded and provided to the driver in a real time display.</p> |
