Automobile intelligent control system based on effective idling stop

Automobile idling stop control system which can make vehicle get good fuel economy and reduce emission as a new energy saving device has received worldwide attention. Working mechanism of idling stop control system was introduced, determination conditions of current idling stop control system were analyzed, and fuel consumption and emissions were analyzed when engine restarted. The current idling stop control system executes idling stop regardless of parking time, fuel consumption and emissions will increase because of short time idling stop. In order to avoid idling stop in a very short time, an intelligent idling stop control system was designed, this system can decide to stop the engine based on vehicle effective stop time. The design ideology and control strategies of intelligent idling stop control system are offered. The simulation runs based on hardware-in-the-loop simulation testing platform, test cycles are CYC_MANHATTAN, CYC_NEWYORKBUS and CYC_WVUCITY. Test results show that: vehicle fuel economy with effective idling stop system improves respectively 12.31%, 20.81% and 10.47% compared with traditional idling stop system.
