摘要： A throttle control system for a vehicle includes a driver input that generates a control signal and a control module that generates a throttle control signal based on the control signal. The control module determines whether the throttle control signal is within one of a first and a second region, determines a compensation factor from a first look-up table when the throttle control signal is within the first region and determines the compensation factor from a second look-up table when the throttle control signal is within the second region. The control module calculates a compensated throttle control signal based on the compensation factor.

摘要： A method and a device for controlling an internal combustion engine. An actuator serves to influence the quantity of exhaust gas recirculated. A loop controller preselects the quantity of exhaust gas to be recirculated on the basis of a setpoint and an actual value which characterizes the quantity of exhaust gas recirculated. A first measured value is determined in a first position (open) of the actuator, and a second measured value is determined in a second position (closed) of the actuator, with the actual value or a correction value being preselectable on the basis of the difference between the two measured values.

摘要： A system and method for learning and controlling an air/fuel mixture ratio for an internal combustion engine are disclosed which can achieve the compatibility of both learning convergence characteristic and accuracy of learning and which can prevent a stepwise change in correction coefficients to a basic fuel supply quantity when the present engine driving condition makes the present one of the driving conditions to the other one of the driving conditions. In a preferred embodiment of the air/fuel mixture ratio learning and controlling system, a plurality of learning maps in which the whole driving region is divided into 16 regions and is divided into 258 regions. The learnings of the air/fuel mixture ratio learning correction coefficients KBLRC1 for the 16 driving regions on the first learning map are followed by those of the other air/fuel mixture ratio learning correction coefficients KBLRC2 for the 256 driving regions on the second learning map. After loads of corrections on the learning correction coefficients KBLRC1 are transferred to those of the learning correction coefficients KBLRC2 for the 256 driving regions, the system reads a modified learning correction coefficient KBLRC2 derived through an interpolation between the 256 region learning map. A final learning correction coefficient KBLRC is set using the read correction coefficient KBLRC2 and the learning correction coefficient KBLRC0 applied to the whole driving region so as to correct the basic fuel supply quantity.

摘要： An air/fuel mixture ratio learning control system for an internal combustion engine using a mixed fuel employs a learnt correction coefficient which is used both in a FEEDBACK mode air/fuel ratio control and in an OPEN LOOP mode air/fuel ratio control. The learnt correction coefficient is derived based on a FEEDBACK air/fuel ratio dependent correction coefficient per one of preselected engine driving ranges and per one of preselected concentration ranges of one fuel component contained in the mixed fuel. The learnt correction coefficient is cyclically derived in a preselected stable engine driving condition during the FEEDBACK mode air/fuel ratio control for updating a previously derived and stored one to minimize a deviation of the FEEDBACK correction coefficient from a reference value. The control system performs the FEEDBACK mode air/fuel ratio control with the FEEDBACK correction coefficient and the learnt correction coefficient, while the control system performs the OPEN LOOP mode air/fuel ratio control with the learnt correction coefficient.
