signaling arrangement for a driven by an internal combustion engine and with a gearbox with stepped turns of a motor vehicle provided for the production of display signals, the to achieve the lowest possible fuel consumption gear to be engaged identify

摘要

The electronic control for a vehicle automatic transmission has sensors to monitor the dynamic parameters of the vehicle and fuel system in order to select the gear ratio to provide the most economic fuel use. A first sensor monitors the engine intake vacuum level, a second the engine speed. Storage circuits provide reference levels for the max. and min. values of each parameter while comparator circuits provide the gear change signals. The whole electronic circuit is simple to assemble and operates for pea fuel efficiency without the driver having to drive a 'feel'. It is of most use in city driving.
