VEHICULAR DRIVE FORCE CONTROL DEVICE |
摘要 |
<p>PROBLEM TO BE SOLVED: To prevent the deterioration of an operability by the big effect of a car speed detection error when the integral control of an engine and a continuously variable transmission is a low car speed. SOLUTION: In this control device, a request axle drive torque T0 * is found out from an acceleration pedal operation amount APS and car speed VSP 31 and a target speed change ratio i* for a target transmission input number of rotation Ni * for generating this T0 * by the lowest fuel consumption under the car speed VSP is found out 32 in order to contribute to a speed change control. A first target engine output torque Te1 for T0 * by dividing T0 * by a torque converter torque ratio (t) 42 and speed change ratio (i) 43 in order is found out and a second target engine output torque Te2 * corresponding to APS is searched from APS and engine number of rotation Ne 46. When VSP is a set car speed VSPs or more, Te1 * is made to the target engine output torque Te * and when it is less than VSPs, Te2 * is made to Te * 47. A target throttle opening TVO* for generating Te * is found out 49 and the engine 1 is controlled by the throttle toward TVO*.</p> |
