Abstract :
An optimization method to tune the PID based idle speed controller gains using an nonlinear engine model is presented. The introduced optimization method is especially valuable for tuning the idle speed controller gains for heavy load scenarios which can occur in the take-off situation, when the driver releases the clutch rapidly. The model-based tuning methodology is evaluated on a PID based idle speed controller embedded in a production type ECU. The experiment has been carried out on a prototype car with a 1.61, direct injection engine to optimize the take-off procedure. In order to get reproducible results a clutch robot has been used
