<p>Vehicle control systems are provided for improving the fuel economy of vehicles by operating their systems in a more efficient manner. Configurations comprise arrangements for controlling compressed air supply, an alternator, a throttle, a pneumatic compressor duty cycle and a cooling fan. The air supply system comprises an air compressor 2, an air dryer 4, an air tank 6, a pressure governor 12, and a controller 16 which is coupled to an economizer valve 8 and to other electrical systems. Controllers of the various systems include an engine ECU (20 fig 4 & 42 fig 8), transmission ECU (22 see fig 4), brake system ECU (24 see fig 4), fuel save ECU (16 see fig 4), gearbox ECU (see fig 8), throttle control ECU (48 see figs 8,9), and fan control ECU (88 see fig 11). The air supply system for example is aimed at improving fuel economy by air storage in response to vehicle braking and/or during an efficient range of engine operation.</p> |
