Abstract
A control system for automatically stopping and starting the vehicle's engine is disclosed, which performs the automatic engine-stop and start control while the negative pressure of the fuel tank is maintained at a suitable level. The system comprises a canister for absorbing evaporating fuel generated in the fuel tank and purging the absorbed evaporating fuel into an air intake system of the engine; a pressure control section for controlling the inner pressure of the fuel tank in a manner such that the internal pressure is maintained at a predetermined level lower than the atmospheric pressure at least while the engine is operated; and an engine stop/start determining section for stopping or starting the vehicle according to the driving state of the vehicle, wherein the engine stop/start determining section determines to prohibit an engine stopping operation when the internal pressure of the fuel tank is higher than the predetermined level.
