Abstract
A vehicle engine control having an automatic start and stop feature for idling the engine to maintain the battery charge includes adjustment for the battery voltage threshold at which the engine is started to recharge the battery. Preferably, the adjustment results from use of an ambient air temperature sensor and a look up table in the control that varies the threshold based on a predetermined relationship between battery voltage and ambient air temperature.
