  • On the prediction of driving performance, an acceleration performance is normally simulated in stall starting condition which is the engine status of full-throttle and high-speed. The lack of transient engine torque data makes the difficulty of predicting an acceleration performance on engine-idle start condition. A experimental equation of transient engine torque is derived from vehicle performance test data. It is applied to simulation the accleration performance prediction on idle starting condition.

  • In this study, an automatic idle stop control system was developed, which automatically stops the idle state engine as it detects the stop state of the car for several seconds and restarts the stopped engine with the driver's electrical signal. It is composed of microprocessor and the related electronic circuits and communicates with ECU and TCU. With accurate and confirmed operating performance, the control system was equipped in the test car which was proceeded the ECE15+EUDC mode test. It is confirmed that the control system, ASG has much favourable effects on reducing the fuel consumption and harmful exhaust emissions.
