Abstract

For the purpose of responding the request engine torque and inhibiting the overshoots of intake air pressure (air density), target intake air pressure algorithm in the nonlinear character of engine intake system is firstly promoted based on Newton Raphson iteration method, and real-time recursive equation of target intake air pressure is obtained. Target intake pressure of transient operation condition is computed. And according to Tustin Derivative method, optimizing throttle efficient area change rate is taken into account. At last, throttle position control strategy is verified on the bench and vehicle. The result shows that the throttle position control strategy can meet engine request torque precisely.
